Wei Hu、Jianzhang Li、Ying Wang 等 5 位作者2011-12-20Journal of Dispersion Science and Technology

Metallomicelles made from two Schiff base manganese(III) complexes (MnL1 and MnL2) and surfactants (CTAB and Brij35) were used as mimetic peroxidase in the catalytic oxidation of phenol by H2O2. The catalytic activity of the complexes (MnL1 and MnL2) were investigated. The mechanism and a kinetic mathematic model of t…

Utilization of Magnetic Nanoparticles for Cancer Therapy

Deryl L. Troyer、Stefan H. Bossmann2011-12-20OpenAlex

The working principle behind MHT is that of exposing MNP to AMF after they have somehow reached a tumor (Jordan et al. 1993; Jordan et al. 2001). Three major factors involved in MHT are the fi eld generator, which generates the AMF, the induction coil, which defi nes the area of high fi eld strength, and the MNPs, whi…
