Design and Synthesis of (E)-2-Hydroxy-5-Alkoxyl Salicylaldoxime Copper Extractant
A kind of novel (E)-2-hydroxy 5-alkoxyl salicylaldoximes copper extractants was designed and synthesized. The synthetic route was started from 1, 4-dihydroxybenzene and the reaction sequence employed for the preparation of the (E)-2-hydroxy-5-alkoxyl salicylaldoxime included monoetherification, formylation and oximina…
Nevada National Security Site Environmental Report 2012 Summary
This document is a summary of the full Nevada National Security Site Environmental Report 2012
Macromol. Rapid Commun. 17/2013
Back Cover: Anisotropic P(VC-co-AAEM)/PS nanoparticles with controllable morphologies are fabricated from noncrosslinked P(VC-co-AAEM) seeds. The phase separation and the number of nucleated bulges of the obtained composite are controlled by adjusting the content of AAEM in seeds and the reaction time of seeded emulsi…
Macromol. Biosci. 9/2013
Front Cover: Derivatization of polysaccharides with hydrophobic moieties can lead to amphiphilic polymers which spontaneously self-assemble in nanohydrogels. On page 1185, P. Matricardi and colleages show how hyaluronic acid derivatives can be used for the formation of such nanohydrogels, which are suitable, as nanode…
Numerical modelling of the magneto-thermal effects of a transverse AC magnetic field on the axial magnetization of a bulk superconducting cylinder
We study the decrease of the magnetization of a bulk superconducting sample when it is subjected to a perpendicular AC magnetic field (crossed field" configuration). The effect of a transverse AC magnetic field on the permanent magnetization of the supercon- ductor are twofold: (i) the superconducting currents are red…
