Synthesis of nanosized LaFeAl11O19 hexaaluminate by mixed metal glycerolate method

A novel method for the synthesis of perspective hexaaluminate LaFeAl₁₁O₁₉ was developed and the product was identified as cubical nanoparticles with a diameter of 45 nm and thoughtfully characterized by SEM-EDS, XRD, BET and HRTEM measurements. As a precursor, amorphous synthetized mixed metal glycerolate was used. Synthesis of the LaFeAl₁₁O₁₉ was made by thermal decomposition of the glycerolate, which was studied by STA measurements. The method is easy to scale up as both glycerolate precursor and subsequent thermal decomposition are simple and relatively affordable methods and the resulting product can be used both in industry and research, especially for catalysis.     

Influence of the hydroquinone ether moieties and Bisphenol A glycerolate diacrylate on the UV stability behavior of new polyurethane materials

A series of the polyurethane materials with different ratios of hydroquinone ether derivatives and bisphenol A glycerolate diacrylate were synthesized using a two-step polymerization procedure. The structures of the obtained polyurethanes were characterized by Fourier transform infrared spectroscopy (FTIR). The influence of the hard segments structure on the thermo-mechanical properties were studied by TGA and stress-strain testing. It was found that with the increase in bisphenol A glycerolate diacrylate content, the new polyurethane materials had improved thermo-mechanical properties, due to the fact that the material develops a crosslinked structure. The durability of the polyurethane films when exposed to ultraviolet radiation was tracked by mechanical behavior and changes in chemical structure. Bisphenol A glycerolate diacrylate-based polyurethane elastomers exhibit improved behavior under UV radiation exposure compared with conventional polyurethanes that are chain-extended with butanediol.

Synthèse à haute température d'un glycérolate de fer au départ d'oxalate ferreux et ferrique

Attempts at synthesizing high temperature crystalline organic complexes starting from glycerol and various iron salts have been achieved, particularly with ferrous and ferric oxalate. For these latter, the powdered reaction products at various stages of the synthesis were studied by X-ray diffraction, i.r. spectroscopy, electron microscopy and chemical analysis. At least two steps are involved in the formation of the glycerolate: (1) a rearrangement of the structure of the starting salt with formation of a sheet structure suitable for the glycerolate, and (2) a reduction or oxidation of metallic ions. Relative rates of these two steps depend on the structural stability of starting materials. Rapid decomposition of ferric oxalate produces the formation of a ferric-rich intermediate product: in this case, the limiting step of the reaction is the progressive reduction of the Fe³⁺ ion. On the other hand, ferrous oxalate breaks up at a rather slow rate and the relative oxidation rate of Fe²⁺ may become fast enough to favour the direct formation of the stable organic complex.     

VCD Studies on Chiral Characters of Metal Complex Oligomers

The present article reviews the results on the application of vibrational circular dichroism (VCD) spectroscopy to the study of stereochemical properties of chiral metal complexes in solution. The chiral characters reflecting on the vibrational properties of metal complexes are revealed by measurements of a series of β-diketonato complexes with the help of theoretical calculation. Attention is paid to the effects of electronic properties of a central metal ion on vibrational energy levels or low-lying electronic states. The investigation is further extended to the oligomers of β-diketonato complex units. The induction of chiral structures is confirmed by the VCD spectra when chiral inert moieties are connected with labile metal ions. These results have demonstrated how VCD spectroscopy is efficient in revealing the static and dynamic properties of mononuclear and multinuclear chiral metal complexes, which are difficult to clarify by means of other spectroscopes.
