Synthesis of 1,4-dihydropyrimidines with immobilized urease: Effect of method immobilization on magnetic supports
(De Gruyter, 2017-08)
The effect of the urease immobilization method was studied on magnetic supports for the Biginelli/Hantzsch reaction. For this purpose, Fe3O4/SiO2 was modified with 3-Aminopropyl-Triethoxysilane and then activated with ...
Immobilized microbial nanoparticles for biosorption
(2020-07-03)
Biosorption processes emerge as an economical and eco-friendly alternative technology for the removal of pollutants present in the environment. One biosorption process application is found in the immobilization of microbial ...
Implementation of immobilization accessories for positioning of small animals for radiation therapy
(Arquivo Brasileiro Medicina Veterinaria Zootecnia, 2017-11-01)
Radiation therapy is a modality that is presenting great advances in veterinary medicine worldwide. In Brazil, this therapeutic option is underachieved. The success of this method depends on several factors, including the ...
Influence of activation on the multipoint immobilization of penicillin G acylase on macroporous silica
(Brazilian Society of Chemical Engineering, 1999-06-01)
Penicillin G acylase is the second most important enzyme used by industry in an immobilized form. Penicillin hydrolysis is its main application. This reaction is used to produce 6-aminopenicillanic acid (6-APA), an ...
