Nano-Structuration of WO Nanoleaves by Localized Hydrolysis of an Organometallic Zn Precursor: Application to Photocatalytic NO Abatement.

WO is a known photocatalytic metal oxide frequently studied for its depollution properties. However, it suffers from a high recombination rate of the photogenerated electron/holes pair that is detrimental to its performance. In this paper, we present a new chemical method to decorate WO nanoleaves (NLs) with a complementary metal oxide (ZnWO) in order to improve the photocatalytic performance of the composite material for the abatement of 400 ppb NO under mild UV exposure.

Photocatalytic degradation of NO/NO gas injected into a 10-m experimental chamber.

This paper investigates a new test method to assess the photocatalytic activity of plasterboards coated with a TiO dispersion under real-world conditions. The degradation of nitrogen oxides NO (NO and NO) is studied and the photocatalytic efficiency under UV illumination is evaluated in a 10-m room after a constant gas injection. Two ultrafine TiO dispersions are used: 0.

Visceral fat mass determination in rodent: validation of dual-energy X-ray absorptiometry and anthropometric techniques in fat and lean rats.

Background: Because abdominal obesity is predisposed to various metabolic disorders, it is of major importance to assess and track the changes with time of this specific fat mass. The main issue for clinicians or researchers is to use techniques for assessing abdominal fat deposition and its accumulation or changes over time, without sacrificing of experimental subjects. In the rat, techniques to investigate in-vivo visceral fat mass are lacking.
