Synthesis and characterization of magnetic cross-linked enzyme aggregate and its evaluation of the alternating magnetic field (AMF) effects in the catalytic activity
(2020-12-15)
A magnetic cross-linked enzyme aggregate (MCLEA) of cellulases and a non-magnetic analogue (CLEA) were synthesized and further investigated. The obtained MCLEA and CLEA showed a high enzyme loading efficiency of 90% and ...
A review of the methods of magnetic nanocomposites synthesis and their applications as drug delivery systems and immobilization supports for lipases
(Research Trends Ltd., 2009-11)
Iron oxide-based magnetic nanoparticles (IONP) that display high saturation and high magnetic susceptibility are of great interest for biotechnological and biomedical applications. Magnetite displays strong ferrimagnetic ...
Optimizing optimum-path forest classification for huge datasets
(2010-11-18)
Traditional pattern recognition techniques can not handle the classification of large datasets with both efficiency and effectiveness. In this context, the Optimum-Path Forest (OPF) classifier was recently introduced, ...

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 ...
Magnetic Investigation of CoFe(2)O(4) Nanoparticles Supported in Biocompatible Polymeric Microsphere
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2009)
Magnetic investigation of spinel ferrite nanoparticles dispersed in biocompatible polymeric microspheres is reported in this study. X-ray diffraction data analysis confirms the presence of nanosized CoFe(2)O(4) particles ...
DIFFUSION OF MAGNETIC FIELD AND REMOVAL OF MAGNETIC FLUX FROM CLOUDS VIA TURBULENT RECONNECTION
(IOP PUBLISHING LTD, 2010)
The diffusion of astrophysical magnetic fields in conducting fluids in the presence of turbulence depends on whether magnetic fields can change their topology via reconnection in highly conducting media. Recent progress ...
