Polyvinylpolypyrrolidoniume tribromide (PVP-Br3) as efficient and metal-free agent for the selective oxidation of alcohols, trimethylsilyl ethers and oximes under mild conditions

open access: yesJournal of Saudi Chemical Society, 2017
Polyvinylpolypyrrolidoniume tribromide (PVP-Br3) was found to be a metal-free and highly efficient oxidizing polymer for the selective oxidation of a variety of benzylic alcohols, deprotection and selective oxidation of trimethylsilyl ethers and oximes ...

Minimally oxidized LDL inhibits macrophage selective cholesteryl ester uptake and native LDL-induced foam cell formation[S]

open access: yesJournal of Lipid Research, 2014
Scavenger receptor-mediated uptake of oxidized LDL (oxLDL) is thought to be the major mechanism of foam cell generation in atherosclerotic lesions. Recent data has indicated that native LDL is also capable of contributing to foam cell formation via low ...

A Practical Synthesis of Betulonic Acid Using Selective Oxidation of Betulin on Aluminium Solid Support

open access: yesMolecules, 2012
The room temperature oxidation of betulin by Cr(VI) compounds in aqueous acetone on solid supports such as alumina, zeolites and silica gel has been studied. The oxidation on alumina support leaded to a single product—betulonic acid—in quantitative yield.

Selective Passivation of GeO2/Ge Interface Defects in Atomic Layer Deposited High-k MOS Structures. [PDF]

open access: yes, 2015
Effective passivation of interface defects in high-k metal oxide/Ge gate stacks is a longstanding goal of research on germanium metal-oxide-semiconductor devices. In this paper, we use photoelectron spectroscopy to probe the formation of a GeO2 interface
