Abstract (Introduction): Vinasse is generated as a residue in the production of ethanol by fermentation-distillation of molasses/sugar cane juice, at a rate of 13 L/L of ethanol. It is an acid liquid, brown in color, characterized by high mineralization and Chemical Oxygen Demand (COD) values of up to 150 000 mg/L, being highly polluting. (Objective): The objective of this research was to evaluate a vinasse treatment process with hydrogen peroxide as a source of hydroxyl radicals at laboratory scale. (Methodology): The vinasse samples, from different distilleries in the province of Tucumán, were characterized following standardized techniques of Standard Methods. The oxidation tests were carried out with different peroxide/vinasses ratios, in a semi-batch reactor, under ambient conditions, measuring COD as an indicator parameter of the treatment. (Results): After 5 days, an 85 % decrease in COD and an increase in the Biodegradability Index were achieved. The kinetics of the oxidative reaction was first order with respect to COD, with an apparent rate constant of 0.3694 1/day. (Conclusions): Although the COD values allowed by local regulations (250 mg/L) were not reached, the proposed treatment is encouraging due to its simplicity, representing a potential option to the environmental challenge represented by vinaze in Latin America.

Resumen (Introducción): La vinaza se genera como residuo en la producción de etanol por fermentación-destilación de melazas/jugos de caña de azúcar, a razón de 13 L/L de etanol. Es un efluente líquido, ácido caracterizado por una elevada mineralización y valores de demanda química de oxígeno (DQO) de hasta 150 000 mg/L, siendo altamente contaminante. (Objetivo): Ealuar un proceso de tratamiento de vinazas con peróxido de hidrógeno, como fuente de radicales hidroxilos, en escala laboratorio. (Metodología): Las muestras de vinazas, de destilerías de la provincia de Tucumán, se caracterizaron según técnicas normalizadas de Standard Methods. Los ensayos de oxidación se realizaron con distintas relaciones de peróxido/vinaza, en un reactor semibatch, en condiciones ambientales, midiendo DQO como parámetro indicador del tratamiento. (Resultados): Al cabo de cinco días se logró una disminución de DQO del 85 % y un aumento del Índice de Biodegradabilidad. La cinética de la reacción oxidativa fue de primer orden respecto de DQO, con una constante aparente de velocidad de 0.3694 1/día. (Conclusiones): Si bien no se lograron los valores de DQO permitidos por la normativa local (250 mg/L), el tratamiento propuesto es alentador por su simpleza, representando una opción potencial al desafío ambiental que representan las vinazas en América Latina.

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 This article intends to propose a methodology to characterize the Financial (In)Sustainability of Brazilian municipalities − materialized through the Municipal Financial Sustainability Index (ISFM) − as opposed to the methodology suggested by the Proposed Amendment to the Constitution (PEC) No. 188, whose agenda is to incorporate small municipalities considered unsustainable. Regarding the methods, we used quantitative, applied, descriptive and explanatory research, of the bibliographical and documentary type, in addition to descriptive statistics and correlation/linear regression. The results demonstrate that the ISFM is more robust compared to the methodology proposed by the PEC. The Index was applied to 5,570 Brazilian municipalities and the national average resulted in 56%. Most Brazilian municipalities classified themselves as “Sustainable” and the statistical analysis significantly demonstrated the existence of a positive correlation between the variables ISFM and Local Development. The contributions of the work turn to the production of research on the subject, still incipient nationally.

This study aimed to isolate, purify and characterize secondary metabolites present in Amburana acreana leaves, native to the state of Rondônia, using classical chromatographic methods and 1D, 2D nuclear magnetic resonance spectroscopy. From the hydroethanolic leaves extract of A. acreana, p-hydroxybenzoic acid, vanillic acid, coumarin, campesterol 3-β-D-glucoside and amburoside B, all known compounds, were identified. To the best of our knowledge, this is the first report of isolation and chemical characterization of secondary metabolites in A. acreana. In addition, in vitro assays indicated that amburoside B does not have inhibitory potential on the growth of gram-negative bacteria. The presence of these compounds suggests that, thus far, amburosides (A and B) could be chemotaxonomic markers of the genus Amburana. isolate Rondônia 1D D spectroscopy A phydroxybenzoic p hydroxybenzoic acid coumarin 3βDglucoside βDglucoside 3 β glucoside identified knowledge addition gramnegative gram negative bacteria far

RESUMO Objetivo: Identificar e caracterizar a população de casos pediátricos encaminhados para o nosso centro de oxigenoterapia hiperbárica. Métodos: Estudo retrospetivo e observacional, que incluiu doentes pediátricos tratados com oxigenoterapia hiperbárica, de 2006 a 2021, no centro de referência de medicina hiperbárica do norte de Portugal. As variáveis de interesse foram extraídas dos processos clínicos eletrônicos. Resultados: O nosso estudo incluiu 134 casos. Os motivos de encaminhamento mais frequentes foram intoxicação por monóxido de carbono (n=59) e surdez súbita neurossensorial (n=41). Em 75 casos (56%) o tratamento foi iniciado em contexto de urgência. Os sintomas de apresentação à admissão variaram entre os diferentes casos, sendo os mais frequentes cefaleias e náuseas/vômitos. No que diz respeito à intoxicação por monóxido de carbono, as fontes mais comuns foram o aquecedor, lareira/braseiro e caldeira. Com relação aos efeitos adversos, foram identificados um caso de intoxicação por oxigênio e quatro casos de barotrauma do ouvido médio. Conclusões: A causa mais frequente de encaminhamento foi a intoxicação por monóxido de carbono. Todos os pacientes evoluíram favoravelmente e foram registrados poucos efeitos adversos, o que enfatiza a segurança desta terapia. Uma vez que a maioria dos pediatras pode não estar informada sobre os potenciais benefícios da oxigenoterapia hiperbárica, é de extrema importância promovê-los para que esta técnica seja cada vez mais implementada.

ABSTRACT Objective: To identify and characterize the population of Pediatric patients referred to our hyperbaric oxygen therapy center. Methods: Retrospective and observational study, including pediatric patients treated with hyperbaric oxygen therapy, from 2006 to 2021, at the hyperbaric medicine reference center in the north of Portugal. Variables of interest were extracted from electronic medical records. Results: Our study included 134 patients. The most frequent reasons for referral were carbon monoxide poisoning (n=59) and sudden sensorineural hearing loss (n=41). In 75 cases (56%), treatment was initiated in an urgent context. Symptom presentation at Emergency Department varied among patients, the most frequent being headache and nausea/vomiting. Concerning carbon monoxide poisoning, the most common sources were water heater, fireplace/brazier, and boiler. Regarding adverse effects, it was identified one case of intoxication by oxygen and four cases of middle ear barotrauma. Conclusions: The most frequent cause for referral was carbon monoxide poisoning. All patients evolved favorably, with few side effects being reported, emphasizing the safety of this therapy. While most pediatricians may not be aware of the potential benefits arising with hyperbaric oxygen therapy, it is of upmost importance to promote them, so that this technique is increasingly implemented.

Alfred Schaeffer (1879-1957) was a German chemist who arrived in Minas Gerais in 1911 hired by the state government to organize the state health service in its newly established capital. He directed the Laboratory of Chemical Analysis of the State, and his analytical methods in dairy and mineral waters became a reference in Brazil. He also became professor of Chemistry at the new Faculty of Medicine of Belo Horizonte and founded the Chemistry Institute of the Engineering School in that city, influencing several students who became important names in Brazilian science. In addition, he was responsible for the assembly and technical coordination of pioneering industries in the dairy and wood distillation sector in the city of Santos Dumont. Later he assumed the post of technical director of Merck, also in Minas Gerais. Moving to Rio de Janeiro, he assumed a chair at the Technical School, working in teaching and research, and remained active even after retiring, publishing in important scientific journals. 18791957 1879 1957 (1879-1957 191 capital State Brazil science addition Dumont Merck Janeiro research retiring journals 1879195 187 195 (1879-195 19 187919 18 (1879-19 1 18791 (1879-1 (1879- (1879 (187 (18 (1 (

The exploration of carbon steel corrosion inhibition in 0.5 mol L-1 H2SO4 using extracts from Hymenaea courbaril (HC) has resulted in significant findings. Extracts from the bark, leaves, fruit pulp, and fruit shell have all proven to be effective corrosion inhibitors, as demonstrated through surface studies and electrochemical methods. Infrared spectroscopy and high-performance liquid chromatography have identified the presence of phenolic compounds, which are known to have corrosion-inhibiting potential. UV-Vis spectroscopy has further revealed the adsorption of extract species on the steel surface. Electrochemical studies have confirmed the inhibition of corrosion, allowing to propose mechanisms of both chemisorption and physisorption. X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS) have provided evidence of the formation of an inhibitory layer, further supporting the inhibition of corrosion. Langmuir isotherms have indicated favorable adsorption of the extracts, while reduced surface roughness suggests improved protection of the steel surface. Activation energy calculations have demonstrated an increase in energy barriers, resulting in slower corrosion rates. These findings suggest that extracts from Hymenaea courbaril show promise as eco-friendly corrosion inhibitors, with potential industrial applications. Further research is needed to optimize the extraction process and fully understand the inhibition mechanisms. 05 0 5 0.

ABSTRACT: This study adopted a more macroscopic perspective to focus on the issue of rural poverty in China. By selecting indicators reflecting various levels of poverty recurrence, considering risk factors across multiple dimensions, and employing advanced methods, we constructed a novel China Rural Poverty Recurrence Risk Index. We utilized a Markov switching model to delve into the mechanisms of poverty recurrence. Building upon this foundation, we developed an advanced poverty recurrence risk early warning system using a convolutional neural network-long short-term memory (CNN-LSTM) model. The system is optimized through mechanism-based predictions to better capture the dynamic changes in poverty recurrence. Empirical results demonstrated that the integrated dynamic monitoring and early warning system have significantly effective outcomes in addressing the recurrence of rural poverty.

Chitosan (CS) blends with collagen (CL) and Aloe vera (AV) have gained significant attention in the biomedical field due to their biocompatibility, biodegradability, and potential for wound healing applications. In this study, we investigated the preparation and characterization of CS/CL and CS/AV blends using selective precipitation and co-precipitation techniques. The synthesis processes were analyzed for yield and 4-hydroxyproline content (in CS/CL blends). The materials were characterized using bromatological analyses, viscosity measurements, Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and scanning electron microscopy (SEM). These eco-friendly methods effectively promoted interactions between the biopolymers, resulting in homogeneous blends with tunable properties. Besides, they are simple, fast, safe, and require minimal infrastructure. This study demonstrated that selective precipitation and co-precipitation are effective methods for producing chitosan/collagen and chitosan/Aloe vera blends. These methods foster interactions and miscibility between the biopolymers, as confirmed by FTIR, XRD, viscosity, and 4-Hy content analyses. They also align with green chemistry principles by avoiding organic solvents, reducing environmental risks, and minimizing waste. The high yields achieved, especially for CS/AV blends (exceeding 96%), make these materials compatible with lyophilization procedures. The absence of segregated phases after appropriate washing underscores their suitability for pharmaceutical formulations and other applications.

ABSTRACT There is great interest in varieties with greater competitive ability against weeds. This can be facilitated by path analysis, which involves the statistical evaluation and interpretation of the relationship between yield and its components. In this analysis, the occurrence of multicollinearity results in inconsistent estimates of the coefficients, and overestimates of the direct effects of the explanatory variables on the response variable. The aim of this study was to identify the characteristics with the greatest direct effect on pod yield and green and dry bean yields in traditional cowpea varieties, evaluated in competition with weeds in two experiments. In addition, the presence of multicollinearity was investigated in the analyses. In Experiment-1, twelve varieties with the highest bean yields in a preliminary evaluation were assessed in a randomized block design with five replications. In Experiment-2, six varieties, selected in the preliminary evaluation, were assessed using two methods of weed management: three of the most productive and three of the least productive. Randomized blocks and split plots were used, with five replications. Multicollinearity, indicated by the number of conditions and the variance inflation values, was greater in Experiment-2. In the six cases under study (three yields x two experiments), the number of pods per plant had the greatest direct effect on yield. analysis components coefficients variable experiments addition analyses Experiment1, Experiment1 Experiment 1, 1 Experiment-1 replications Experiment2, Experiment2 2, 2 Experiment-2 management used Multicollinearity values Experiment2. 2. experiments, , experiments) Experiment-

RESUMO Objetivo: Descrever as características epidemiológicas de pacientes pediátricos com doença falciforme (DF) e avaliar o uso de plantas medicinais concomitantemente ao tratamento medicamentoso. Métodos: Realizou-se revisão de prontuários de pacientes pediátricos de uma instituição pública com nível de atendimento terciário; o critério de seleção foi ser criança ou adolescente com DF em acompanhamento pediátrico neste ambulatório. Nos prontuários dos pacientes selecionados foi procurado o registro do uso de plantas com finalidades medicinais. Resultados: Foram revisados 154 prontuários (100% dos pacientes ativos desse ambulatório): 99 crianças e 55 adolescentes. O genótipo predominante foi SS (58,4%), seguido do SC (29,2%). O uso de ao menos uma medicação para a DF foi relatada em 95,5% dos prontuários. Em 70,1% dos prontuários havia o relato do uso de plantas medicinais, em 276 citações, sendo 64 plantas citadas ao todo; destas, seis espécies foram citadas para o tratamento da doença de base (DF), sendo “ora-pro-nobis” (Pereskia aculeata) a principal. Das 276 citações de plantas medicinais nos prontuários, 60,5% incluíram o uso de plantas medicinais em sintomas gripais e/ou COVID-19 (tanto prevenção quanto tratamento), sendo relatadas 35 para este uso, exclusivamente ou não. Essa foi a principal finalidade de uso encontrada nos prontuários dos pacientes, seguida do uso para sintomas de dor (14,2% das citações). Conclusões: Notou-se que a maioria dos pacientes avaliados faz uso da medicina convencional, aliada à tradicional/ complementar/ alternativa, o que leva à necessidade de mais estudos nessas áreas, especialmente na pediatria, visando principalmente à segurança do paciente.

ABSTRACT Objective: The aim of this study was to describe the epidemiological characteristics of pediatric patients with sickle cell disease (SCD) and evaluate the use of medicinal plants in these patients concomitantly with their drug treatment. Methods: This is a review of the medical records of pediatric patients at a public institution with tertiary care. The selection criterion was to be a child or adolescent with SCD undergoing pediatric follow-up at this outpatient clinic. In the medical records of the patients selected, records of the use of plants for medicinal purposes were sought. Results: In total, 154 records (100% of total active patients followed in this clinic) were reviewed: 99 children and 55 adolescents. The predominant genotype was SS (58.4%), followed by SC (29.2%). The use of at least one medication for SCD was reported in 95.5% of the medical records. The use of medicinal plants was reported by 70.1% of patients, with 276 citations in the medical records referring to 64 different types of plants. Six plants were used for the treatment of SCD, the main one being Lemonvine/Ora-pro-nóbis (Pereskia aculeata). The use of medicinal plants was reported for flu-like symptoms and/or COVID-19 (both for prevention and treatment) by 60.5% of the citations, with 35 different plants reported for this use, exclusively or not. This use was followed by pain symptoms (14.2% of citations). Conclusions: The majority of patients in this study use both conventional and traditional/complementary/alternative medicine, highlighting the need for more studies in the area, with a special focus on patient safety.

RESUMO Objetivo: Avaliar a correlação entre a religiosidade e o uso de álcool em adolescentes com fissura orofacial. Métodos: Estudo transversal, desenvolvido em um hospital público e terciário brasileiro entre dezembro de 2021 e março de 2022. A coleta de dados foi híbrida, e foram utilizados três instrumentos: Questionário Sociodemográfico, Escala de Religiosidade de Durel e o Alcohol Use Disorders Identification Test. Para a análise estatística foram empregados os testes: qui-quadrado, exato de Fisher, Mann-Whitney e o coeficiente de correlação de Spearman, além das análises de forças de correlação linear e de regressão logística bivariada. O nível de significância adotado para todos os testes foi de 5% (p≤0,05). Resultados: Participaram 370 adolescentes, com média de idade de 15,2 anos (±1,8). Entre eles, 23 (5,4%) usavam o álcool de forma arriscada ou prejudicial. A religiosidade organizacional, não organizacional e a intrínseca foram significativamente menos frequentes entre adolescentes que utilizavam o álcool de forma arriscada ou prejudicial (p=0,005; p<0,001 e p=0,002, respectivamente). Evidenciou-se correlação moderada entre o uso arriscado ou prejudicial do álcool e a religiosidade não organizacional (r=0,31; p=0,002) e a intrínseca (r=0,36; p<0,001). Apresentaram maiores chances de usar o álcool adolescentes do sexo masculino (p<0,001; odds ratio — OR=6,58), com idade mais próxima aos 18 anos (p<0,001; OR=1,37) e que não praticavam a religião (p<0,001; OR=6,48).

ABSTRACT Objective: To evaluate the correlation between religiosity and alcohol use among adolescents with orofacial clefts. Methods: Cross-sectional study, developed in a Brazilian public and tertiary hospital, between December 2021 and March 2022. Data collection was hybrid, and three instruments were used: Sociodemographic Questionnaire, Durel Religiosity Scale, and the Alcohol Use Disorders Identification Test. For statistical analysis, the following tests were used: χ2, Fisher’s Exact, Mann-Whitney and Spearman’s Correlation Coefficient, in addition to analyses of linear correlation strength and bivariate logistic regression. The significance level adopted for all tests was 5% (p≤0.05). Results: 370 adolescents participated, with a mean age of 15.2 years (±1.8). Among them, 23 (5.4%) used alcohol riskly or harmfully, being more frequent among male adolescents (p=0.001), those of mixed race (p=0.046), attending high school (p=0.011), with no religion (p<0.001), or who did not attend religious services (p<0.001). Levels of organizational, non-organizational and intrinsic religiosity were significantly lower among adolescents with risky or harmful alcohol use (p=0.005; p<0.001 and p=0.002, respectively). There was a moderate correlation between risky or harmful alcohol use and non-organizational (r=0.31; p=0.002) and intrinsic (r=0.36; p<0.001) religiosity. Male adolescents (p<0.001; OR=6.58), closest in age to 18 years (p<0.001; OR=1.37), and non-practitioners of religion (p<0.001; OR=6. 48) presented higher odds of risky or harmful alcohol use. Conclusions: Adolescents with higher levels of organizational and intrinsic religiosity used less alcohol, while males, closest in age to 18 years, and non-practitioners of religion presented higher odds of using alcohol riskly or harmfully.

ABSTRACT Objective: The aim of this study was to describe the phases of a decannulation protocol and the results from its application in hospitalized children. Methods: This is a retrospective, observational study. Data were collected from medical records of decannulated patients followed up in a pediatric hospital in Belo Horizonte, Minas Gerais between 2011 and 2021. Results: Among the children followed up in the service (n=526), 23% (n=120) were successfully decannulated. Children aged between 2 months and 16 years, with a mean age of 4 years, 69% of whom were male, were evaluated. About 75% of the patients have tracheostomy due to upper airway obstruction and 60% of these due to acquired subglottic stenosis. At the beginning of the decannulation protocol, 5.5% of the patients had moderate oropharyngeal dysphagia, while 80.4% had normal swallowing. Correction in the upper airway pre-decannulation was performed in 39.5% of the patients, dilation in 63.8%, and endoscopic correction was performed in 55.3%. After performing the decannulation, none of the patients had complications. Conclusions: The described decannulation protocol is safe, since no complications such as death and need for recannulation happened.

ABSTRACT Objective: The aim of this study was to investigate the contextual factors associated with the quality of life (QOL) of Brazilian children aged 0–12 years during the strict period of social isolation. Methods: This observational cross-sectional study was conducted between July and September 2020 using an online questionnaire on QOL-related family factors and the Pediatric Quality of Life Inventory (PedsQL™). Results were analyzed by multinomial logistic regression analysis. Results: The sample had 849 children, mostly from the South Region of Brazil (75%), white (83%), with typical development (79%), sedentary (68%), using screen (85%) for >3 h/day (44%). Their mothers were their main caregivers (90%). The following variables were significantly associated with high scores of QOL: typical health status (OR 2.38; 95%CI 1.60–3.55; screen time ≤2 h/day (OR 1.62; 95%CI 1.17–2.24); social distancing considered as “easy” (OR 1.67; 95%CI 1.20–2.32), and stimulation of the child by the family (OR 1.93; 95%CI 1.08–3.45). Conclusions: This study indicates that the family context can influence children’s QOL, especially during the COVID-19 pandemic and home environment reorganization.

RESUMO Objetivo: Investigar os fatores contextuais associados à qualidade de vida (QV) de crianças brasileiras de zero a 12 anos, em momento de ápice de distanciamento social. Métodos: Estudo observacional, transversal, online, de julho a setembro de 2020, com questionário sobre fatores do contexto familiar associados à QV e Inventário Pediátrico sobre QV — PedsQL™. A análise dos dados foi feita por de regressão logística multinomial. Resultados: A amostra foi de 849 crianças, na maioria da Região Sul (75%), brancas (83%), com desenvolvimento típico (79%), sedentárias (68%), com uso de telas (85%) em tempo >3h/dia (44%). As mães eram as cuidadoras principais (90%). Foram significativamente associadas a escores mais elevados de QV: a condição de saúde típica (odds ratio — OR 2,38; intervalo de confiança de 95% — IC95% 1,60–3,55), o tempo de tela ≤2h/dia (OR 1,62; IC95% 1,17–2,24), o distanciamento social considerado “fácil” (OR 1,67; IC95% 1,20–2,32) e a família afirmar estimular a criança (OR 1,93; IC95% 1,08–3,45). Conclusões: Este estudo mostra que o contexto familiar pode influenciar a QV de crianças, especialmente no período de pandemia e de reorganização do ambiente domiciliar.

Novel nanocomposites synthesized with pollen grain, as a precursor, were tested for CO2 adsorption performance. The pollen-derived carbons were obtained by direct calcination (PC), calcination followed by KOH-chemical activation (PCKOH), and MgO incorporation using high-energy ball-milling (PC-MgO and PCKOH-MgO). All the as-prepared materials were texturally, morphologically and structurally characterized by N2 physisorption, scanning electron microscopy (SEM-EDS) and X-ray diffraction (XRD); CO2 adsorption/desorption was measured by thermogravimetry. The four materials were able to adsorb CO2 at 30 ºC and 1 bar, but PCKOH-MgO, with the high surface area (12.4 m2 g-1), total pore volume of (0.13 cm3 g-1) and microporosity, was the best (2.06 mmol g-1 and percentage of adsorption (Qad) = 9.06%, at 1 bar). This result is due to the synergic effect of both synthesis methods. Neither temperature (from 30 to 100 ºC), nor pressure (from 1 to 15 bar), improved the adsorption process of PCKOH-MgO. CO2 desorption times at 300 ºC were 47 min for PCKOH-MgO and 30 min for the other adsorbents, showing the possibility of cycling. Based on the obtained results, the PCKOH-MgO activated carbon nanocomposite stands as a promising adsorbent to be potentially used for industrial CO2 capture applications and to contribute to long-term solutions to avoid dangerous climate-change and reduce CO2 emissions. grain precursor CO performance pollenderived derived PC, PC , (PC) KOHchemical KOH chemical PCKOH, PCKOH (PCKOH) highenergy energy ballmilling ball milling PCMgO PCKOHMgO.
