Generalized van der Waals theory for phase behavior of two-dimensional nematic liquid crystals: II. Phase coexistence and adsorption
(American Physical Society, 2020-12)
Adsorption of asymmetric particles or molecules into monolayers is important for many biological and technologically relevant physical systems. In-plane ordering can drastically affect adsorption and phase behavior. In ...
Adsorptive properties of mesoporous silica modified with Lewis base molecule and its application in the preconcentration of Cu(II), Co(II), and Cd(II) from aqueous media
(2018-01-01)
Cocondensation and postfunctionalization methods were employed to synthesize a mesoporous silica with large surface area (795.1 ± 1.1 m2 g− 1) modified with 4-amino-5-hydrazino-1,2,4-triazole-3-thiol, which was successfully ...
Carboxymethylated bacterial cellulose: An environmentally friendly adsorbent for lead removal from water
(Elsevier, 2018-12)
Carboxymethylated bacterial cellulose (CMBC) was synthesized under controlled reaction condition to provide a material with a degree of substitution (DS) that guarantees that the characteristic water insolubility of cellulose ...
Fenton-like degradation of methylene blue using Mg/Fe and MnMg/Fe layered double hydroxides as reusable catalysts
(2020-03-15)
In this work, the Layered Double Hydroxide (LDH) containing magnesium (Mg) and iron (Fe) was modified with Mn to investigate the effect of the addition from the structural and catalytic point of view. These materials were ...
Adsorção de herbicidas utilizando biochar obtido a partir de resíduos de madeira
(Universidade Federal de Santa MariaBrasilEngenharia QuímicaUFSMPrograma de Pós-Graduação em Engenharia QuímicaCentro de Tecnologia, 2022-02-26)
Residues of sawdust of the forest species Cedrela fissilis were modified, with a part of the
sample being only physically modified (BCC), while the other was also chemically activated
with zinc chloride (ZnCl2) as an ...
Renewable and Electroactive Biomass-Derived Tubes for CO2Capture in Agroindustrial Processes
(American Chemical Society, 2021-06)
Tube-shaped renewable carbon materials were developed to work as separation agents for CO2 capture in agroindustrial and intensive farming facilities. The tubes have electrical properties and moderate CO2 adsorption ...
Adsorption of organic pollutants by amine functionalized mesoporous silica in aqueous solution. Effects of pH, ionic strength and some consequences of APTES stability
(Elsevier, 2019-10)
A mesoporous silica with MCM-41 type pore array was synthesized by hydrothermal method and then was functionalized with known amounts of 3-aminopropyltriethoxysilane (APTES) in order to study the selective adsorption towards ...
Synthesis of mesoporous silica-coated magnetic nanoparticles modified with 4-amino-3-hydrazino-5-mercapto-1,2,4-triazole and its application as Cu(II) adsorbent from aqueous samples
(2016-03-30)
This study presents an alternative, rapid, and environment-friendly synthesis procedure of a magnetic core-shell mesoporous SBA-15 silica composite, its functionalization with 4-amino-3-hydrazino-5-mercapto-1,2,4-triazole ...
Estudo da purificação do àcido clavulânico utilizando processo contínuo de adsorsão.
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2003-10-02)
Clavulanic acid (CA), a beta-lactam antibiotic, has been known for its commercial and therapeutic importance. This antibiotic is produced by an actinomicete, Streptomyces clavuligerus, and has a combined use with penicillins, ...
