Os relacionamentos afetivos passaram por transformações significativas ao longo do último século, marcados mudanças sociais, culturais e subjetivas que reconfiguram os vínculos amorosos. O casamento tornou-se mais tardio e, em muitos casos, transitório; a virgindade perdeu centralidade nos rituais o sexo adquiriu maior desprendimento, sendo vivenciado sem compromisso. A decisão de ter filhos deixou ser uma obrigatoriedade, tornando-se escolha individual. Na contemporaneidade, há valorização...
Abstract Magnetic particles (MNPs) offer attractive possibilities in biotechnology. MNPs can get close to a target biological entity, as their controllable sizes range from few nanometres up tens of nanometres, and surface be modified add affinity specificity towards desired molecules. Additionally, they manipulated by an external magnetic field gradient. In this work, the study ferric oxide (Fe 3 O 4 ) with different coating agents was conducted, particularly terms strategies for antibody...
We present molecular simulations of gases in mesoporous MOF MIL-100(Fe) impregnated with ionic liquids [Bmim+][PF6–] and [Bmim+][Tf2N–]. Adsorption pure carbon dioxide, methane, nitrogen, typical mixtures found flue natural gas are studied. Increases CO2 adsorption, sitting, selectivity were investigated to provide an impregnation alternative a stable material that could be experimentally successful. The presence liquids, particular [Bmim+][SCN–], increases uptake within the pressure range...
Despite the great industrial importance of zeolite LTA, there is still a gap in characterization methods, based on adsorption related to hindered diffusion standard probe gases, such as N2 and Ar. LTA has three-dimensional porous structure with high degree symmetry; however, variations location cations, notably S2 S3 sites, lead different energy levels supercages. Herein, we propose extend pore type distribution (PTD) methodology, recently applied for metal–organic frameworks, materials. As...
We propose a pore size analysis methodology for carbonaceous materials that reduces complexity while maintaining the significant elements of structure-property relationship. This method chooses limited number representative pores, which will constitute simplified kernel to describe distribution (PSD) an activated carbon. In this study we use sizes 7.0, 8.9, 18.5, and 27.9 Å N 2 isotherms at 77.4 K determine PSD is later applied predict adsorption equilibrium other gases. demonstrate ability...
The pore-size distribution (PSD) of an activated carbon (AC) sample, which is obtained by molecular simulation using a specific probe gas, does not always reproduce the adsorptive behaviour that sample with other gases. Moreover, different gases generate distinct distributions for same AC. These facts go against concept PSD, must be unique given irrespective gas used. We analyzed adsorption isotherms WV-1050 AC nitrogen at 77 K, dioxide 298 K and methane 303 yielding their respective PSDs,...
Hydrotalcite-like compounds are anionic clays of scientific and technological interest for their use as ion exchange materials, catalysts modified electrodes. Surface phenomenon important all these applications. Although conventional analytical methods have enabled progress in understanding the behavior solution, an evaluation at atomic scale dynamics ionic interactions has never been performed. Molecular simulation become extremely useful tool to provide this perspective. Our purpose is...
A simulação molecular tem sido bastante utilizada como ferramenta de caracterização estruturas metalorgânicas (MOFs) para aplicações que envolvem a adsorção. Nos estudos da adsorção através molecular, os campos forças convencionais têm criticados por falhar na representação das isotermas adsorção, especialmente, nas MOFs com sítios metálicos abertos. Por outro lado, Teoria do Funcional Densidade (DFT) pode ser determinar parâmetros campo força mais precisos. Em geral, cálculos quânticos...
