Characterization of light-cured dimethacrylate resins modified with silsesquioxanes
(Springer, 2010-11-24)
Methacrylate-functionalized silsesquioxanes (SSQO) were synthesized by the hydrolytic condensation of 3-(methacryloxypropyl) trimethoxysilane (MPTMS)
using dimethacrylate monomers as reactive solvent. Resins containing ...
Model for the electrocatalysis of hydrogen evolution
(American Physical Society, 2009-06)
We show how a theory for electrocatalysis developed in our group can be combined with density-functional theory in order to obtain free-energy surfaces for electrochemical reactions. The combined theory is applied to the ...
Desolvation effects on the dissociation energy of diatomic molecules:Ab initio study of the dissociation of Li-F in polar media
(Springer-Verlag, 1993)
The potential curve of the ground state dissociation of Li-F in water has been studied by a combination of a standard ab initio Hartree-Fock procedure and a perturbative reaction field approach. The electrostatic solute-solvent ...
Moléculas de Corynebacterium pseudotuberculosis com potenciais antigênicos
(Instituto de Ciências da SaúdeDepartamento de BiointeraçãoPrograma de Pós-Graduação em Biotecnologia da Renorbio -(Rede Nordeste de Biotecnologia)UFBAbrasil, 2018-05-04)
Corynebacterium pseudotuberculosis é o agente causador da linfadenite caseosa dos caprinos e ovinos, enfermidade associada a perdas econômicas diretas no setor pecuário. Além de ter um curso crônico, o seu tratamento com ...
Recovery of copper and gold from computer printed circuit boards by bioleaching with Aspergillus niger
(2020)
A recuperação de metais a partir de lixo eletrônico e o desenvolvimento de novos materiais em micro/nanoescala, utilizando compostos orgânicos e inorgânicos, têm recebido destaque em diversas áreas devido ao potencial de ...
Imobilização de papaína em membranas de nanocelulose bacteriana
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Ciência e Tecnologia AmbientalUTFPR, 2019-03-27)
Bacterial nanocellulose is a type of cellulose produced in the form of a hydrogel membrane by some bacteria and has unique properties such as high purity and crystallinity, high water retention capacity (> 98%), mechanical ...
Calixarene and Resorcarene Based Receptors: From Structural and Thermodynamic Studies to the Synthesis of a New Mercury(II) Selective Material
(AMER CHEMICAL SOC, 2011)
Materials used in current technological approaches for the removal of mercury lack selectivity. Given that this is one of the main features of supramolecular chemistry, receptors based on calix[4]arene and calix[4]resorcarene ...
Comparative study of thermal, mechanical and structural properties of polybutadiene rubber isomers vulcanized using peroxide
(Elsevier, 2016-07)
Three commercial polybutadiene rubber (BR) compounds (high cis, medium cis and high vinyl content) were vulcanized at 433 K, using different amounts of dicumyl peroxide (DCP) as curing agent. To analyze the structural ...
Desenvolvimento de novos materiais lignocelulósicos e quitinosos com potencial aplicação em química ambiental
(Universidade Federal de Minas GeraisUFMG, 2015-03-25)
This work describes the preparation of new chelating materials derived from cellulose and chitosan. The first part describes the chemical modification of sugarcane bagasse (B) and cellulose (C) using Meldrum's acid as ...
