The Schröeder-van Laar equation to predict the theoretical eutectic melting temperature values was applied to a set of fourteen binary mixtures (UR1 to UR14). The fourteen binary mixtures belong to a structurally diverse group of organic molecules. They are represented by the 5-membered heterocycles containing N-S and N-O rings, flexible methylene chains (RH), semi-rigid semi-fluorinated chains (RF), and hydrogen bonds (HB). A virtual screening totalizing ninety-one possible theoretical combinations was planned. The UR1 to UR14 were prepared by mixing individual components using the calculated mole fractions. The experimental (Te) and theoretical (Tt) temperatures for the eutectic melting points were determined using polarized optical microscopy (POM) and differential scanning calorimetry (DSC) techniques. Heterogeneous mixtures were formed for components with large structural diversity as seen by POM. During the melting of the mixtures, irregular behavior through the segregation of the components was recorded. The study showed that the similarities in structural diversities favor the formation of homogeneous mixtures, with Te values approaching Tt, as predicted by the Schröeder-van Laar equation and by the theory of eutectic mixtures. Liquid crystal properties were affected in homogeneous binary mixtures containing one of the individual liquid crystal components. Schröedervan Schröeder van UR (UR UR14. .

The study of atomic spectroscopy has a profound relationship with quantum mechanics and its comprehension. Since Bohr’s success with a theory for the atom, it has been established that spectrum lines originate from transitions between different states. Moreover, the analysis of complex spectra reveals that there are groups of spectral lines that compose what is called a multiplet. To rationalize the multiplet structure, we need models to characterize and label the quantum states. The characterization of the atomic states is a common subject in classes of physical chemistry and inorganic chemistry, and there are basically two approaches to infer and label the energy states: (i) the LS coupling scheme and (ii) the jj coupling scheme. Usually, only the LS coupling is presented, and this ends up omitting its underlying assumptions. Here, we present a survey of both approaches, highlighting their premises and their adequacy towards different groups of the periodic table, ions, and excited states configurations. We show that by using benchmark data together with the Landé interval rule, the appropriate use of the jj coupling to understand the atomic spectra of heavier atoms is easily conveyed. comprehension Bohrs Bohr s atom Moreover structure i (i ii (ii Usually presented assumptions Here table ions configurations rule conveyed

In order to extract hesperidin from Citrus aurantium L. through green and efficient ways, a novel method based on deep eutectic solvent (DES) assisted extraction has been developed. Compared to known alkali extraction and acid precipitation or organic solvent (ethanol, methanol) extraction, this new DES system of choline chloride/diethanolamine (DES-14) method exhibited excellent extraction efficiency for hesperidin. Under optimal conditions, the extraction yield of hesperidin reached 6.26 ± 0.05%. Further studies with infrared spectroscopy, 1H nuclear magnetic resonance, and density functional theory showed the DES-14 was formed mainly through the interaction of H-bond and van der Waals forces. In addition, scanning electron microscopy and density functional theory revealed the strong dissolving capacity, and the H-bond formation between DES-14 and hesperidin, as well as van der Waals forces all contributed to efficient extraction of hesperidin. The results provide a new strategy for efficient extraction and utilization of hesperidin in Citrus.

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. .

A new alkaloid, named brazoide Ε (6), three known steroids (campesterol, β-sitosterol, stigmasterol), two glucosides (3-O-β-D-glucopyranosylsitosterol and 3-O-β-D-glucopyranosyl stigmasterol) and sucrose were isolated from the leaves and stems of Justicia wasshauseniana. Their structures were characterized using high-resolution electrospray ionization mass spectrometry (HRESIMS), nuclear magnetic resonance (1D and 2D NMR), and infrared (IR) spectroscopy. To reinforce the structural proposal, an acetylated derivative (6a) was obtained and its data compared to 6. Moreover, circular dichroism spectroscopy (CD) analysis was performed to determine the absolute stereochemistry, time-dependent density functional theory (TD-DFT) at the wB97X-D/def2-TZVP level, adopting functionals M06-2X and wB97X-D and base aug-cc-pVDZ, was employed to confirm the CD analysis. alkaloid 6, 6 , (6) campesterol, campesterol (campesterol βsitosterol, βsitosterol β sitosterol, sitosterol β-sitosterol stigmasterol, stigmasterol 3OβDglucopyranosylsitosterol OβDglucopyranosylsitosterol 3 O D glucopyranosylsitosterol 3OβDglucopyranosyl OβDglucopyranosyl glucopyranosyl wasshauseniana highresolution high resolution HRESIMS, HRESIMS (HRESIMS) 1D NMR, NMR NMR) IR (IR proposal 6a a (6a Moreover (CD stereochemistry timedependent time dependent TDDFT TD DFT (TD-DFT wB97XD/def2TZVP wB97XDdef2TZVP wBXDdefTZVP wB97X D/def2 TZVP def2 wB X def level M062X MX M06 2X M wB97XD wBXD augccpVDZ, augccpVDZ aug cc pVDZ, pVDZ aug-cc-pVDZ (6 (HRESIMS def2TZVP XD XDdef wBX Ddef2 Ddef D/def M0 ( defTZVP

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.

This paper elucidates the inseparable connection between the pursuit of a more ecologically sustainable society and the quest for socioeconomic justice. It also demonstrates why Unconditional Basic Income (UBI) is an effective policy to act on both fronts. First, the corresponding theory on environmental and socioeconomic oppression sheds light on the argument that both types of domination stem from the same historical process and are inherently interconnected. Addressing one without considering the other is essentially flawed; they are both features and consequences of present society. Acknowledging the historical debt owed to vulnerable economic classes and developing countries is imperative. Green republicanism could potentially establish a theoretical foundation for social-ecological thinking. Defining freedom as non-domination and applying this concept to nature are essential prerequisites for overcoming socioeconomic and environmental oppression. UBI is presented and discussed theoretically as a strong solution to address these two challenges. It serves not only as a means to facilitate the transition to a post-productivist society, transforming labor relations, but also as a catalyst for the development of circular economies and more sustainable occupations. Additionally, the basic income policy implemented in the city of Maricá, Brazil, is cited as empirical evidence showcasing the environmental and socioeconomic values of UBI. justice (UBI fronts First interconnected flawed imperative socialecological social ecological thinking nondomination non challenges postproductivist post productivist relations occupations Additionally Maricá Brazil

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

Alzheimer’s disease (AD) is a most common form of dementia and results in memory loss, disorientation, impaired thinking and changes in personality as well as mood. The dementia cases mostly turn into the Alzheimer’s disease (AD). Another disease, the Parkinson’s disease (PD), mainly affects dopaminergic neurons in substantia nigra. A series of previously synthesized quinolone-triazole hybrids were investigated and evaluated for their anti-acetyl cholinesterase and against monoamine oxidase reactive properties through in silico characterization. The ground state electronic properties were determined by electron density of the compounds through DFTs (density functional theory) calculation. The geometries of all compounds were optimized using Becke-3-parameter-Lee-Yang-Parr (B3LYP) method and 6-311g basis set. Docking studies were conducted using the AutoDock and Molecular Operating Environment (MOE) software and the results of the potent derivatives found to be encouraging. The data confirmed that all the compounds have drug-like properties and was further confirmed by ADMET (absorption, distribution, metabolism, excretion and toxicity) properties.

Two novel alkyl thiophene-modified pyrene derivatives (1)-(2) were created and synthesized using palladium-catalyzed Stille coupling processes and Friedel-Crafts reaction of pyrene. The polycyclic aromatic groups of the thiophene-modified pyrene were oxidized with Ag[Al(OC(CF3)3)4] to provide the insensitive radical cations 1•+-2•+ based on the alkyl thiophene-modified pyrene derivatives. Nuclear magnetic resonance (NMR), electron paramagnetic resonance (EPR), UV-Vis spectroscopy, and density functional theory (DFT) calculations, were used to investigate their structures and properties. The pyrene moieties were the primary location of the electron spin distribution, with a little overflow onto the outer thiophene moieties. Due to the different substituent groups, free radicals 1•+ 2•+ exhibit some different properties. Compound 1•+ is the most extensive thiophene-modified pyrene radical cation that has been reported. These species are anticipated to have wide-ranging potential in the areas of optoelectronic materials and semiconductors. thiophenemodified modified 12 1 2 (1)-(2 palladiumcatalyzed palladium catalyzed FriedelCrafts Friedel Crafts AgAlOCCF334 AgAlOCCF Ag Al OC CF3 3 4 CF Ag[Al(OC(CF3)3)4 1•+2•+ 1•+-2• NMR, NMR , (NMR) EPR, EPR (EPR) UVVis UV Vis spectroscopy DFT (DFT calculations properties distribution 1• 2• reported wideranging wide ranging semiconductors (1)-( AgAlOCCF33 Ag[Al(OC(CF3)3) 1•+2• 1•+-2 (NMR (EPR (1)- AgAlOCCF3 Ag[Al(OC(CF3)3 1•+2 1•+- (1) Ag[Al(OC(CF3) (1 Ag[Al(OC(CF3 ( Ag[Al(OC(CF

RESUMO A Teoria da Dependência dos Recursos procura entender como fatores externos influenciam o comportamento da organização, sua dependência e diversificação de recursos. Este estudo analisa a influência dos desempenhos econômico-financeiro e esportivo na diversificação das receitas de 24 clubes de futebol brasileiros. A composição das receitas foi analisada por meio da classificação da APFUT, adicionada da categoria “Receitas Financeiras”, enquanto o indicador Hirschman-Herfindahl adaptado foi utilizado para medir o nível de diversificação. Os resultados indicam que as principais receitas dos clubes são Direitos de Transmissão, Repasse de Direitos Federativos e Patrocínio. Os modelos apontaram efeitos positivos da rentabilidade e Ranking da CBF, e negativo do acesso à primeira divisão no nível de diversificação, indicando a relevância de elementos econômicos e esportivos. Este estudo contribui para a análise dos desempenhos esportivo e econômico-financeiro, os quais afetam a gestão de receitas, bem como endossa a discussão sobre a necessidade de diversificação das receitas como uma das medidas para evitar dificuldades financeiras. organização recursos econômicofinanceiro econômico financeiro 2 brasileiros APFUT Receitas Financeiras, Financeiras , Financeiras” HirschmanHerfindahl Hirschman Herfindahl Transmissão Patrocínio CBF esportivos econômicofinanceiro, financeiro, financeiras

ABSTRACT The Resource Dependence Theory seeks to understand how external factors influence an organization's behavior, dependency, and diversification of resources. This study analyzes the influence of economic-financial and sports performance on the revenue diversification of 24 Brazilian football clubs. The composition of the revenues was analyzed through the APFUT classification, with the addition of the "Financial Revenues" category, while the adapted Hirschman-Herfindahl Index was used to measure the level of diversification. The results indicate that the clubs' main revenues are Broadcasting Rights, Transfer of Federative Rights, and Sponsorship. The models pointed to the positive effects of profitability and Brazilian Football Confederation (CBF) Ranking and the negative effect of promotion to the first division on the diversification level, indicating the relevance of economic and sports elements. This study contributes to the analysis of sports and economic-financial performance, which affect revenue management, and endorses the discussion on the need for revenue diversification as one of the measures to avoid financial difficulties. organizations organization s behavior dependency resources economicfinancial 2 clubs classification Financial Revenues category HirschmanHerfindahl Hirschman Herfindahl Rights Sponsorship CBF (CBF elements management difficulties

Asphaltene aggregation mechanism is still a nebulous and controversial issue. Many authors argue that the aggregation of its components is due to π-stacking interactions, nonetheless, alkyl chains, heteroatoms, and even acidic groups are also constituents of asphaltenes and can play an important role in the chemistry of asphaltene. Excimers from pyrene are easily detected by fluorescence and were used in the current study to probe the effect of the side chain on the π-stacking capacity of pyrene. Pyrene was acylated with acyl chains varying from two to twelve carbon atoms, and the effect of the variation of the acyl chain length on excimer formation was followed by fluorescence emission spectroscopy. The results revealed that as the side chain grows from two to twelve carbon atoms the excimer/monomer ratio decreases and the excimer heat of formation drops from ΔH = -6.00 to -1.29 kcal mol-1. Further, the crystal structure of octanoyl pyrene (PC8) indicates that in the crystal structure, the aromatic moiety faces the acyl chain. This result was corroborated by density functional theory (DFT) calculations. Finally, the results were compared with two different asphaltenes and indicate that π-stacking cannot be assumed as the main driving force for asphaltene aggregation. issue πstacking π stacking interactions nonetheless heteroatoms spectroscopy excimermonomer monomer 6.00 600 6 00 -6.0 1.29 129 1 29 -1.2 mol1. mol1 mol 1. mol-1 Further PC8 PC (PC8 DFT (DFT calculations Finally 6.0 60 0 -6. 1.2 12 2 -1. mol- (PC 6. -6 -1 -

Abstract The objective of this paper is to problematize Ramón Grosfoguel’s statements, specifically regarding Aníbal Quijano. I claim that the accusation of “epistemic racism” that Grosfoguel made, according to which Quijano would not have recognized one of his intellectual debts, lacks foundation in authentic sources. Contextualizing the “coloniality of power” more broadly, I argue that Grosfoguel does not consider key aspects of the Peruvian author’s biography, both his political and intellectual background and the style of his work. In addition, examining the relationship between Quijano and the Peruvian and Latin American intellectual tradition will illuminate crucial paths in the trajectory of the “coloniality of power” theory. Thus, the grave accusation of “epistemic racism” that the Puerto Rican author made must be questioned since Quijano’s academic trajectory reveals that the elaboration of “coloniality” is endowed with a historicity according to which the ideas of race and racism are part of the overall theory-building process.
