The present study is dedicated to the development of aluminum borate luminescent powders which appear as promising and more environmental-friendly than conventional phosphors. different steps powder synthesis, in particular precursors (inorganic organic) ratios calcination conditions, are adjusted by studying resulting optical features get a broader warmer white emission. As shown previous work...

At the occasion of the fiftieth birthday of the introduction of the term ‘metal atom cluster’ by F. A. Cotton in inorganic chemistry, it is the good time to make a review on the advances in the engineering of molecular assemblies and nanomaterials based on octahedral Re6 metal atom clusters. The latter exhibit unique intrinsic structural and physicochemical properties (orthogonal disposition of...

Hybrid organic-inorganic catalysts have been extensively investigated by several research groups in the last decades, as they allow combining structural robust-ness of inorganic solids with versatility organic chemistry. Within field hybrid catalysts, synthetic strategies based on silica are among most exploitable, due to convenience sol-gel chemistry, array silyl-derivative precursors that can...

Surface functionalized nanoparticles have found their applications in several fields including biophotonics, nanobiomedicine, biosensing, drug delivery, and catalysis. Quite often, the nanoparticle surfaces must be post-coated with organic or inorganic layers during the synthesis before use. This work reports a generally one-pot synthesis method for the preparation of various inorganic-organic ...

Type 4 adenovirus infection of HeLa cells effected a marked increase in synthesis of the saline-soluble DNA fraction, but not the host-cell DNA (the water-soluble fraction). This was demonstrated by the marked increase in specific activity of saline-soluble DNA but not water-soluble DNA when P(32)-inorganic phosphate or sodium formate-C(14) was employed. When these isotopes were used to label c...

A conventional and general route has been exploited to the high yield synthesis of many kinds of highly crystalline metal oxide and mixed oxide nanocrystals with different morphologies including belt, rod, truncated-octahedron, cubic, sphere, sheet via the hydrothermal reaction of inorganic precursors in aqueous solution in the presence of bifunctional 6-aminohexanoic acid (AHA) molecules as a ...

dehydrogenase (Rose et al., 1969). The ,H labelling of ['HI lactate in 2H,0 and the 'H labelling of [2H]lactate in 'H,O has been studied. A comparison of the exchange in whole cells and lysates has also been undertaken. The detailed measurement of exchange kinetics permitted by the n.m.r. technique has revealed the dependence of the exchange on the different enzyme activities and on the triose ...

a two-week tunnel study was conducted in monterrey, mexico during june 2009 to characterizevolatile organic compound (voc) emissions from the local vehicle fleet and estimate the correspondingemission factors (efs). the loma larga tunnel (llt), a 532 meter-long structure that is mainly used by lightduty gasoline-powered vehicles was used as the experimental set-up. ambient air samples (2-hour a...
