Structural and photophysical properties of rare-earth complexes encapsulated into surface modified mesoporous silica nanoparticles.

The encapsulation of [Eu(dbm)3phen] into functionalized mesoporous silica nanoparticles (MSN) has been carried out to study the effect of chemical environments on the photoluminescence properties of the rare-earth complex. Surface functionalization was achieved by the reaction of the silanol groups on the surface of mesoporous silica with different organosilylating agents such as (3-aminopropyl...

Preparation and Characterization of Rare Earth Doped Fluoride Nanoparticles

This paper reviews the synthesis, structure and applications of metal fluoride nanoparticles, with particular focus on rare earth (RE) doped fluoride nanoparticles obtained by our research group. Nanoparticles were produced by precipitation methods using the ligand ammonium di-n-octadecyldithiophosphate (ADDP) that allows the growth of shells around a core particle while simultaneously avoiding...

A Modified-One Pot Synthesis of Diaminoglyoxime

The one pot reaction of glyoxal and hydroxylamine hydrochloride in aqueous sodium hydroxide was found to be a safe and inexpensive method for the preparation of diaminoglyoxime. By increasing stoichiometric ratio of the hydroxylamine hydrochloride and decreasing the solvent volume, the product yield increased considerably (~ 70%).

Preparation of rare earth metals

The production of over 400 grams of pure gadolinium metal by reduction of the anhydrous chloride by calcium in tantalum vessels is described; yields were over 97%. The use of the same techniques in an attempt to prepare yttrium metal were partially successful.

Preparation and characterization of TiO2 nanoparticles surface-modified by octadecyltrimethoxysilane

Titanium dioxide (TiO2) nanoparticles surface-modified by octadecyltrimethoxysilane (commercial name WD-11) are prepared via in situ surface-modification in dehydrated ethanol at room temperature. As-obtained TiO2 nanoparticles are characterized by means of Fourier transform infrared spectrometry, thermogravimetric, X-ray diffraction and transmission electron microscope. The tribological proper...
