Abstract Monkey mortality in Costa Rica is due, in most cases, to anthropogenic factors, such as deforestation, forest fragmentation, lack of tree connectivity, and tourism development in most coastal areas. The latter factor has caused the death of at least 450 monkeys per year due to electrocution, as a result of the increase in electrical wiring that has arisen in the different regions with urban development. Faced with this threat, proposals have been developed to avoid the danger, such as the construction of appropriate passage infrastructure for monkeys, the placement of insulated wiring, and the protection of electrical transformers. Using the morphometric measurements of the four species of monkeys native to Costa Rica (Alouatta palliata, Ateles geoffroyi, Saimiri oerstedii, and Cebus imitator), a model of safe and functional aerial passages or bridges for them was designed, the foundations of which are discussed in this article.

Resumen La mortalidad de los monos en Costa Rica se debe, en la mayoría de los casos, a factores antropogénicos, como la deforestación, la fragmentación de los bosques, la falta de conectividad arbórea y el desarrollo turístico en la mayoría de las zonas costeras. Este último factor ha provocado la muerte de al menos 450 monos por año debido a la electrocución, a raíz del aumento del cableado eléctrico que ha surgido en las diferentes regiones con desarrollo urbanístico. Ante esta amenaza se han elaborado propuestas para evitar el peligro, como la construcción de infraestructura de paso apropiada para los monos, la colocación de cableado aislado y la protección de los transformadores eléctricos. Utilizando las medidas morfométricas de las cuatro especies de monos nativas de Costa Rica (Alouatta palliata, Ateles geoffroyi, Saimiri oerstedii y Cebus imitator), se diseñó un modelo de pasos aéreos o puentes seguros y funcionales para ellos, cuyos fundamentos se discuten en el presente artículo.

Abstract (Introduction): The search for techniques and methods for managing sludge generated during wastewater treatment is necessary to ensure sustainable sanitation in the medium term in Latin America. An interesting approach involves converting sludge into a biosolid usable in agriculture through alkaline sanitization. (Objective): We evaluated this technique’s efficacy and economic and environmental viability for obtaining an agriculturally usable type A biosolid from municipal wastewater treatment plant (WWTP) sludge. (Methodology): To this end, the efficacy in reducing microbiological parameters was experimentally tested at the laboratory scale using quicklime, for anaerobic and aerobic WWTP sludge. The experimental results fed a benefit/cost analysis model and a life cycle assessment. (Results): It was confirmed that applying a 40 % lime dose allowed the obtention of a type A biosolid with non-detectable concentrations of pathogenic microorganisms, which remained in that condition for more than 30 days. Additionally, the benefit/cost and life cycle analyses concluded that this option would be more attractive than sludge disposal in a landfill, due to the corresponding savings in chemical compounds (fertilizers, agricultural lime). (Conclusions): Therefore, alkaline sanitization can be considered suitable for WWTP sludge management. Its application on a larger scale should be further investigated in the country and the Latin-American region, considering the risk associated to the presence of heavy metals too.

Resumen (Introducción): La búsqueda de técnicas y modelos de gestión del lodo generado durante el tratamiento de las aguas residuales es necesaria para garantizar un saneamiento sostenible a mediano plazo en América Latina. Una vía interesante consiste en convertir el lodo en un biosólido aprovechable en la agricultura por medio de la higienización alcalina. (Objetivo): Se evaluó la eficacia y la viabilidad económica y ambiental de esta técnica para la obtención de un biosólido tipo A aprovechable en la agricultura a partir de lodo de planta de tratamiento de aguas residuales (PTAR) ordinaria. (Metodología): Para ello se probó experimentalmente en escala de laboratorio la eficacia en el decaimiento de parámetros microbiológicos higienizados con cal viva, usando lodo anaeróbico y aeróbico de PTAR. Los resultados experimentales alimentaron un modelo de análisis de beneficio/costo y de ciclo de vida. (Resultados): Pudo corroborarse que la aplicación de dosis de cal de 40 % permitió obtener un biosólido tipo A con concentraciones de microorganismos patógenos no detectables, lo cual se mantuvo en esa condición por más de 30 días. Además, el análisis de beneficio/costo y de ciclo de vida permitieron concluir que esta opción sería más atractiva que la disposición del lodo en un relleno sanitario, debido al ahorro correspondiente en compuestos químicos (fertilizantes o cal agrícola) derivado de su aprovechamiento. (Conclusiones): Por lo tanto, la técnica de higienización alcalina puede considerarse como adecuada para la gestión del lodo de PTAR y su aplicación a mayor escala debe investigarse en mayor detalle en el país y la región latinoamericana, considerando también el riesgo de presencia de metales pesados en este subproducto.

Abstract: The homogeneity of wood growth ring width is associated with greater rigidity and mechanical strength of the material. Therefore, understanding ring width homogeneity would be useful for visually grading sawn wood for structural applications. However, the effect of homogeneity on mechanical performance of wood has not been quantified. In this study, the dispersion of the ring width was analyzed to assess its predictive value for elasticity and axial bending strength in Quercus robur (european oak) wood beams. To carry out the study, 26 adult oak trees were felled in Galicia (northwestern Spain). The stems obtained were cut and sawn to produce planks, which were air-dried and subsequently planned to produce beams with target dimensions 2000 mm × 100 mm × 50 mm. For a sample of 52 of these beams, we measured the axial bending strength, the elastic modulus in axial bending, the wood density and moisture content, as well as the percentage of sapwood and the width of each growth ring in the cross section. The descriptive variables of the ring homogeneity, calculated using data from all rings in each beam (standard deviation, variance, interquartile range), were more closely related to mechanical properties. Beams with more homogeneous rings exhibited significantly higher elastic modulus and axial bending strength, with the strongest correlation observed between ring width variance and axial bending elastic modulus (R = -0,41**). However, the correlations observed do not justify developing a predictive model for elasticity or mechanical strength based solely on ring width homogeneity, although mechanical behavior is significantly influenced by ring homogeneity. Consequently, this characteristic could be incorporated into visual strength grading standards for oak wood.

Resumen: La homogeneidad en la anchura de anillos de crecimiento de la madera se asocia a una mayor rigidez y resistencia mecánica del material. Por ello, conocer la homogeneidad de la anchura de los anillos sería útil en la clasificación visual de la madera aserrada con fines resistentes. Sin embargo, no está cuantificada la influencia de la homogeneidad en el comportamiento resistente de la madera. En este trabajo se analizó la dispersión de la variable anchura de anillos para determinar su valor predictivo sobre la resistencia y la elasticidad a flexión axial en vigas de madera de Quercus robur (roble europeo). Para realizar el estudio se talaron 26 robles adultos en Galicia (noroeste de España). Los fustes obtenidos fueron aserrados para obtener tablones, que fueron secados al aire y posteriormente fueron cepillados hasta obtener vigas de dimensiones nominales 2000 mm × 100 mm × 50 mm. En una muestra de 52 de dichas vigas se obtuvo el módulo resistente a flexión axial, el módulo elástico a flexión axial, la densidad y la humedad de la madera, así como el porcentaje de albura y la anchura de cada anillo de crecimiento en la sección transversal de cada viga. Las variables descriptivas de la homogeneidad de anillos en cuyo cálculo intervienen los datos de todos los anillos de la viga (desviación típica, varianza, rango intercuartílico) estaban más relacionadas con las propiedades mecánicas. Las piezas con anillos homogéneos presentaban un módulo elástico y una resistencia a flexión estática significativamente mayores, siendo la correlación más destacada la existente entre la varianza de la anchura de anillos y el módulo elástico a flexión (R = -0,41**). No obstante, el valor de las correlaciones obtenidas no justifica la construcción de un modelo predictivo de la elasticidad o de la resistencia mecánica usando solo la homogeneidad de la anchura de anillos como variable predictora. Sin embargo, dado que el comportamiento mecánico se ve significativamente influenciado por la homogeneidad de los anillos, esta característica podría incorporarse en las normas de clasificación visual de la madera de roble con fines resistentes.

Faced with the global challenge of water treatment, the investigation of the removal of endocrine disruptor compounds (EDCs) in aquatic environments is essential to protect human and animals health. In this study, a novel nanocomposite was prepared from biochar from agricultural waste (corn cob) and maghemite (γ-Fe2O3) nanoparticles, named PCCN, to remove four EDCs (triclosan, 17α-ethinylestradiol, methylparaben, and bisphenol A) from aqueous solutions by adsorption. For the characterization of PCCN, the advanced techniques Fourier transform infrared spectroscopy (FTIR), Brunauer-Emmett-Teller analysis (BET), pH of point of zero charge (pHpzc), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and thermogravimetry (TGA) were employed. Competitive adsorption equilibrium studies of EDCs were performed with PCCN and compared to unmodified biochar (PCC). The pH effect showed that optimal adsorption of EDCs was at pH 8.0 for PCC and pH 6.0 for PCCN. The salt concentration did not influence EDCs in the adsorption. In the adsorption isotherm, the results fitted the Freundlich isotherm model (R2 > 0.903) and the adsorption kinetics were well described by the pseudo-second-order model (R2 > 0.985). Furthermore, the desorption studies indicated that the PCCN can be reused. Thus, the investigation suggests PCCN has promising potential in the removal of EDCs from wastewater. treatment (EDCs health study corn cob γFe2O3 γFeO γ Fe2O3 Fe O (γ-Fe2O3 nanoparticles triclosan, triclosan (triclosan 17αethinylestradiol, 17αethinylestradiol αethinylestradiol 17α ethinylestradiol, ethinylestradiol α 17α-ethinylestradiol methylparaben A FTIR, FTIR , (FTIR) BrunauerEmmettTeller Brunauer Emmett Teller BET, BET (BET) pHpzc, pHpzc (pHpzc) SEM, SEM (SEM) TEM, TEM (TEM) Xray X ray XRD (XRD TGA (TGA employed PCC. .

Asphaltenes are complex molecules with a tendency to aggregate. This property can be an issue for the oil industry due to CO2 reinjection into reservoirs to mitigate these gas emissions. The present theoretical study aimed to study the CO2 interaction with no-substitute and substituted coronene as an asphaltene model compound at CAM-B3LYP-D3/6-311G(d,p) level. The electronic properties were evaluated using harmonic oscillator model of aromaticity (HOMA), quantum theory of atoms in molecules (QTAIM), and reduced density gradient (RDG) methods. The results showed that the coronene’s functionalization by a sulfur atom changes the coronene’s electronic structure. However, functionalization does not change the type of interactions between the monomers, as they remain predominantly van der Waals interactions. CO2 interaction with substituted coronene barely changed due to the presence of sulfur atoms. However, in dimers, the position of the heteroatom directly influences the interaction with CO2, although it is insufficient to change the interaction’s magnitude. For this reason, our results indicate that the sulfur heteroatom in asphaltenes should be addressed. However, new studies must be conducted by increasing the number of substituents, CO2 numbers, and the model size. aggregate CO emissions nosubstitute no substitute CAMB3LYPD3/6311Gd,p CAMB3LYPD36311Gdp CAMBLYPDGdp CAM B3LYP D3/6 311G d,p D3 6 d p B LYP D G CAM-B3LYP-D3/6-311G(d,p level HOMA, HOMA , (HOMA) QTAIM, QTAIM (QTAIM) RDG (RDG methods coronenes s structure However monomers dimers magnitude reason addressed substituents numbers size CAMB3LYPD3 6311Gd CAMB LYPD Gd Gdp BLYP D36 D3/ dp (HOMA (QTAIM CAMBLYPD CAMB3LYPD

Two poly(acrylic acid-b-acrylamide) copolymers, and a poly(acrylic acid) homopolymer were synthesized via reversible addition-fragmentation chain transfer (RAFT) polymerization and tested for nickel removal from aqueous media. RAFT was used for better interchain composition homogeneity and to facilitate the synthesis of the block copolymers. Liquid-phase polymer-based retention (LPR) was used to compare the nickel binding capacity. Uptake tests were carried out at pH 3.0, 4.0, and 5.0. Nickel adsorption isotherms in the range of 1 to 7 mmol L−1 were achieved and the Langmuir adsorption model was applied. Maximum binding capacity (Qm) of Ni2+ at 298 K depended on the composition of the copolymers and pH. The polyacid block (PAA) was the major structural feature responsible for high values of nickel binding. All materials presented better uptake at higher pH, probably due to polyacid deprotonation and the increase in the electrostatic interactions. Up to approximately 100 mg of nickel per gram of homopolymer could be retained at pH = 5.0. Even though the presence of a poly(acrylamide) block decreases the binding capacity compared to PAA, that block has a specific contribution to nickel binding and can also provide better features to the material as better solubilization, and others. polyacrylic poly acrylic acidbacrylamide acid b acrylamide acid-b-acrylamide additionfragmentation addition fragmentation (RAFT media Liquidphase Liquid phase polymerbased polymer based LPR (LPR 30 3 0 3.0 40 4 4.0 50 5 5.0 L1 L L− applied Qm (Qm Ni2 Ni 29 PAA (PAA interactions 10 polyacrylamide poly(acrylamide solubilization others 3. 4. 5. 2

Selenium-containing compounds exhibit diverse biological activities, such as antioxidative, anti-inflammatory, and cancer preventive effects. Using Caenorhabditis elegans as a model organism, we assessed the toxicity, neuroprotective, antioxidant properties, and impact on longevity of 11 selenoacetylenes. Their toxicity and bioactivities varied based on molecular structure. Selenoacetylenes with butyl substituents were toxic to Galleria mellonella larvae. The presence of but-3-in-2-ol radical increased antiprotozoal activity against Tetrahymena pyriformis. Compared to the positive control (Nimitz® EC), selenoacetylenes were less toxic to nematode worms and eggs. Selenoacetylenes significantly reduced amyloid beta (Aβ) paralysis in C. elegans CL4176 worms, increased longevity by 18 to 22%, along with improving survival after oxidative or thermal stress. Galantamine, showed inferior results. These findings enhance our understanding of selenoacetylenes on neuroprotection, antioxidant activity, and longevity in C. elegans. Future mammalian studies will further elucidate mechanisms and explore the potential therapeutic use of selenoacetylenes in treating Alzheimer’s disease and longevity.

RESUMO Objetivo: Avaliar a sazonalidade da bronquiolite aguda no Brasil durante a temporada 2020–2022 e compará-la com a das temporadas anteriores. Métodos: Os dados de incidência de internações por bronquiolite aguda em lactentes <1 ano de idade foram obtidos do Departamento de Informática da base de dados da Saúde Pública Brasileira para o período entre 2016 e 2022. Esses dados também foram analisados por macrorregiões do Brasil (Norte, Nordeste, Sudeste, Sul e Centro-Oeste). Para descrever características sazonais e de tendência ao longo do tempo, utilizamos o Modelo de Médias Móveis Integradas Autorregressivas Sazonais. Resultados: Em comparação com o período pré-COVID-19, a incidência de hospitalizações relacionadas com bronquiolite aguda diminuiu 97% durante as intervenções não farmacológicas (março de 2020 – agosto de 2021), mas aumentou 95% após a flexibilização das intervenções não farmacológicas (setembro de 2021 – dezembro de 2022), resultando no aumento geral de 16%. Durante o período pré-COVID-19, as hospitalizações por bronquiolite aguda seguiram um padrão sazonal, que foi interrompido em 2020–2021, mas recuperaram-se em 2022, com um pico ocorrido em maio, aproximadamente 4% superior ao pico pré-COVID-19. Conclusões: Este estudo ressalta a influência significativa das intervenções contra a COVID-19 nas hospitalizações por bronquiolite aguda no Brasil. A restauração de um padrão sazonal em 2022 sublinha a interação entre as medidas de saúde pública e a dinâmica das doenças respiratórias em crianças pequenas.

ABSTRACT Objective: To evaluate the seasonality of acute bronchiolitis in Brazil during the 2020–2022 season and compare it with the previous seasons. Methods: Data from the incidence of hospitalizations due to acute bronchiolitis in infants <1 year of age were obtained from the Department of Informatics of the Brazilian Public Health database for the period between 2016 and 2022. These data were also analyzed by macro-regions of Brazil (North, Northeast, Southeast, South, and Midwest). To describe seasonal and trend characteristics over time, we used the Seasonal Autoregressive Integrated Moving Averages Model. Results: Compared to the pre-COVID-19 period, the incidence of hospitalizations related to acute bronchiolitis decreased by 97% during non-pharmacological interventions (March 2020 – August 2021) but increased by 95% after non-pharmacological interventions relaxation (September 2021 – December 2022), resulting in a 16% overall increase. During the pre-COVID-19 period, hospitalizations for acute bronchiolitis followed a seasonal pattern, which was disrupted in 2020–2021 but recovered in 2022, with a peak occurring in May, approximately 4% higher than the pre-COVID-19 peak. Conclusions: This study underscores the significant influence of COVID-19 interventions on acute bronchiolitis hospitalizations in Brazil. The restoration of a seasonal pattern in 2022 highlights the interplay between public health measures and respiratory illness dynamics in young children.

The inhibition of the fatty acid amide hydrolase (FAAH), an endocannabinoid system component, emerged as a potentially new therapeutic target for a range of clinical disorders such as acute and chronic pain. Some α-ketoheterocycle derivatives demonstrated interesting analgesic and anti-inflammatory activities in vitro. Ligand-Based Drug Design techniques such as knowledge graph convolutional networks (kGCN) and hologram quantitative structure-activity relationship (HQSAR) using α-ketoheterocycle derivatives from five different datasets were generated to discover the relation between the chemical structures and the inhibition activity. Meanwhile, structure-based drug design simulations as interaction fields (MIF), molecular docking, and ligand sites studies (LSI) from FAAH were performed using Autogrid software and FTmap/FTsite servers. The results of both studies were merged to propose predictive models. The resulting kGCN model demonstrated adequate accuracy area under the curve by receiver operating characteristic (AUC-ROC 0.7922). From contribution maps of the Ligand-Based Drug Design (LBDD) models and the generated probes using MIF and LSI, it was observed that the oxazole ring, the ketone group, and the apolar chain present in the structures of the inhibitors are important, besides the evidence of the Cys269 and Val270 residues importance for the potential interaction, confirmed by carried docking studies. These fragments and structural information can be used to carry out new FAAH potential inhibitors studies and report kGCN as an accurate classification technique.

To control vehicle emissions, the new homologation process must be reported according to the California Maximum Incremental Reactivity (MIR) scale’s procedure to calculate the ozone forming potential (OFP) of each new vehicle. This work calculates an MIR scale suitable for the Brazilian reality. Meteorological and hourly pollutant data from the Bangu Automatic Air Quality Station was inventoried and processed from March to September 2020 to adjust OZIPR Lagrangean model and obtain the MIR scale by making small increments in the concentrations of each volatile organic compounds (VOC) and calculate the ozone increase/decrease. It was found that the VOC that had the greatest impact on ozone formation was 1,2,4-trimethylbenzene, with 2.06 ppb O3 ppbC-1 VOC. The OFP was calculated based on the VOC emissions of a vehicle and it was found a value of 9.421 mg O3 km-1, a much lower value when compared using the California MIR scale of 136.608 mg O3 km-1. It is concluded that meteorological conditions and VOC speciation data in the air mixture in the studied region directly affect the photochemical reactions of ozone formation.

RESUMO: A China é o maior país produtor de melão em todo o mundo. A aplicação extrema de fertilizantes durante o plantio de melão representa uma séria ameaça ao meio ambiente e à segurança alimentar, portanto, como promover os agricultores a usar fertilizante orgânico verde tornou-se um tópico importante. Este estudo introduziu criativamente a consciência verde no quadro estendido da teoria do comportamento, planejado para explorar os fatores decisivos da intenção dos agricultores de melão de aplicar fertilizante orgânico verde. O modelo de equações estruturais é usado para investigar a intenção de comportamento de 543 agricultores de melão no Condado de Leting, China. Os resultados sugerem que tanto a norma subjetiva quanto a consciência verde podem afetar positiva e significativamente o comportamento dos produtores de melão. Quando a norma subjetiva aumenta em 1, o desvio padrão, a intenção do agricultor aumenta em 1,028 desvio padrão. Para cada aumento de 1 desvio padrão na consciência verde, a intenção dos agricultores aumentou em 0,703 desvio padrão.

ABSTRACT: China is the biggest muskmelon producing country across the world. Extreme application of fertilizer during planting of muskmelon poses a serious threat to the environment and food safety, so how to promote farmers to use organic fertilizer has become an important topic. This study creatively introduced green awareness into the extended framework of theory of planned behavior to explore the decisive factors of muskmelon farmers’ behavior intention to apply green organic fertilizer. The structural equation model is used for investigating behavior intention of 543 muskmelon farmers in Leting County, China. The results suggested that both subjective norm and green awareness can affect muskmelon farmers’ behavior intention positively and significantly. When the subjective norm increases by 1 standard deviation, the farmers’ intention increases by 1.028 standard deviation; for every 1 standard deviation increase in green awareness, the farmers’ intention increased by 0.703 standard deviation.

RESUMO: O uso de métodos não destrutivos e de baixo custo para determinação de área foliar tem ganhado importantes aplicações. Os objetivos da pesquisa foram (i) propor um método não destrutivo para estimar a área foliar da cultura da mamona e (ii) construir equações que estimem com precisão e rapidez a área foliar da espécie. Foram coletadas mil folhas sadias e expandidas de cinco cultivares de mamona (New Zealand Purple, Sipeal, Carmencita, Amarelo de Irecê e IAC-80), sendo coletadas 200 folhas de cada uma. O comprimento máximo, largura máxima e área foliar foram calculados para cada folha. Foi calculado o produto entre comprimento e largura (LW). Foram realizados testes com diferentes modelos de regressão linear e não linear entre área foliar e dimensões lineares das folhas de cada cultivar. Os modelos utilizados foram linear, linear sem intercepto e potência. Os critérios para escolha dos melhores modelos para estimar a área foliar da mamona foram maior coeficiente de determinação, maior coeficiente de correlação linear de Pearson, menor critério de informação de Akaike, maior índice de concordância de Willmott e menor raiz do erro quadrático médio. As equações que apresentaram melhores critérios para estimativa da área foliar das cultivares de mamona foram aquelas que utilizaram o produto entre comprimento e largura, em comparação às equações que utilizaram apenas uma dimensão foliar. O modelo ŷ = 0,439 × LW pode ser utilizado para estimar com precisão e rapidez a área foliar da mamona por meio de medidas lineares das folhas, utilizando o produto entre comprimento e largura (LW), independente da cultivar escolhida.

ABSTRACT: Using non-destructive and low-cost methods to determine leaf area has gained important applications. The research objectives were (i) to propose a non-destructive method to estimate the leaf area of castor bean crops and (ii) to build equations that accurately and quickly estimate the leaf area of specie. One thousand healthy and expanded leaves of five castor bean cultivars (New Zealand Purple, Sipeal, Carmencita, Amarelo de Irecê, and IAC-80) were collected, and 200 leaves were collected from each. The maximum length, maximum width, and leaf area were calculated for each leaf. The product between length and width (LW) were calculated. We performed tests with different linear and non-linear regression models between leaf area and linear leaf dimensions of each cultivar. The models used were linear, linear without intercept, and power. The criteria for choosing the best models to estimate the leaf area of castor beans were a higher coefficient of determination, more elevated Pearson’s linear correlation coefficient, lower Akaike information criterion, higher Willmott agreement index, and smallest root mean square error. The equations that presented the best criteria for estimating the leaf area of castor bean cultivars were those that used the product between length and width, compared to equations that used only one leaf dimension. The model ŷ = 0.439 × LW can be used to accurately and quickly estimate the castor bean leaf area through linear measurements of the leaves, using the product between length and width (LW), regardless of the cultivar chosen.

The sixth IPCC report states that a proper conception of climate justice that can address the complexity of the phenomenon of anthropogenic climate change as a whole requires considering not only one but rather three dimensions of justice today: redistributive, procedural, and recognition dimensions. In this article, my focus is on exploring the latter dimension, drawing special attention to climate policies addressing cultural-identity issues. In the first section, I illustrate how climate policies can be connected to discriminatory practices against minority cultures and their identities. To do so, I take the struggles of Black movements against environmental racism and the struggles of Indigenous peoples against a colonialist cultural heritage as case studies. In the second section, I look into the most advanced normative model to address the dimension of recognition, its advantages, and how it addresses the so-called ‘institutionalization of cultural patterns’ in climate policies: the Nancy Fraser model. Finally, in the third section, I investigate an aspect that remains open. It concerns the matter of how to use institutional authority to ‘deinstitutionalize’ non-ecological cultural patterns, while respecting pluralism and avoiding falling into the risks of institutional paternalism. today redistributive procedural article culturalidentity identity issues section identities so studies advantages socalled called institutionalization patterns Finally open ‘deinstitutionalize deinstitutionalize nonecological non ecological paternalism

RESUMO: Materiais de base biológica provenientes de proteínas, polissacarídeos e lipídios têm sido estudados como alternativas biodegradáveis aos plásticos sintéticos, bem como matrizes para incorporação de substâncias bioativas. Neste contexto, a pectina é um polissacarídeo utilizado para produzir filmes flexíveis para embalagens de alimentos. A própolis é uma mistura complexa de substâncias resinosas com propriedades antimicrobianas e outras propriedades biológicas que podem ser usadas para produzir embalagens ativas para alimentos. Contudo, a aplicação de tais materiais ainda está limitada devido à sua natureza hidrofílica. Portanto, este trabalho teve como objetivo avaliar experimentalmente as isotermas de sorção e o calor isotérmico de sorção de filmes de pectina-própolis nas temperaturas de 15, 25, 30 e 35 °C, e determinar o modelo matemático que melhor se ajusta aos dados experimentais obtidos. A pectina foi extraída do mesocarpo do pequi, fruta amplamente consumida no bioma cerrado brasileiro que gera grande quantidade de cascas (exocarpo e mesocarpo) descartadas.

ABSTRACT: Bio-based materials from proteins, polysaccharides, and lipids have been studied as biodegradable alternatives to synthetic plastics, as well as matrices for incorporation of bioactive substances. In this context, pectin is a polysaccharide used to produce flexible food packaging films. Propolis is a complex mixture of resinous substances with antimicrobial and other biological properties that can be used to generate active food packaging. However, the application of such materials is still limited due to their hydrophilic nature. Thus, this experimentally evaluated the sorption isotherms and isothermal heat of sorption of pectin-propolis films at temperatures of 15, 25, 30, and 35 °C, and determined the mathematical model that best fits the experimental data obtained. The pectin was extracted from pequi mesocarp, a widely consumed fruit in the Brazilian cerrado biome that generates large amounts of peels (exocarp and mesocarp) which are discarded. Among the mathematical models studied, the Sigma Copace model was found to best represent the hygroscopic behavior of the pectin-propolis films. The isothermal heat of sorption decreased with increasing water content, and the films presented similar behavior to agricultural products. The understanding of such film’s behavior contributed to the application of pectin-propolis films produced using pequi mesocarp as a pectin source.

In this study, it was investigated chitosan (CHIT) films in the presence or absence of cellulose nanofibers (CNF) and silver nanoparticles (AgNP), whose chemical interactions involving metallic surfaces were characterized by surface-enhanced Raman scattering (SERS) spectroscopy. Changes in the morphology were analyzed through atomic force microscopy (AFM) and scanning electron microscopy (SEM). SEM and AFM micrographs revealed that the incorporation of CNF significantly altered CHIT films, leading to changes in the polymer topography and surface texture due to intimal interactions between CNF and the CHIT matrix. Raman spectra of CHIT and CNF/CHIT films showed similar profiles, reflecting comparable molecular structures of both modified biopolymers. However, SERS spectra of both films, after recovering with AgNP, demonstrated distinct spectral profiles. Innovatively, density functional theory (DFT) calculations of an oligomer model for CHIT were employed to assign the vibrational modes observed in the SERS spectra, which allowed identify key interactions between CHIT moieties and AgNP surfaces. SERS results revealed that chemical adsorption of CHIT on AgNP surfaces occurs through interactions of glycosidic oxygen and amino groups. Such findings provide insights into the structural and chemical behavior of this nanocomposite, highlighting its potential for advanced biological applications. study (CHIT (CNF , (AgNP) surfaceenhanced enhanced (SERS spectroscopy (AFM SEM. .
