J Nanosci Nanotechnol. 2014 Aug;14(8):6072-6. doi: 10.1166/jnn.2014.8834.

Lanthanum cerium oxide nanoparticles have been synthesized by co-precipitation method. In this method, nanoparticles in hydroxide form are obtained and then these nanoparticles are calcined at high temperature. Thermo gravimetric analysis (TGA), X-ray diffraction (XRD), electron dispersive spectroscopy (EDS),...

Chemistry. 2015 Oct 19;21(43):15108-12. doi: 10.1002/chem.201502973. Epub 2015 Sep 03.

The aldol reaction represents an important class of atom-economic carbon-carbon bond-forming reactions vital to modern organic synthesis. Despite the attention this reaction has received, issues related to chemo- and regioselectivity as well as reactivity of readily enolizable electrophiles remain....

Homoleptic mononuclear nine-coordinate lanthanum(III) and europium(III) tris-complexes [Ln(N(∧)N(∧)O)3]·nH2O with two tridentate N-benzylbenzimidazole pyridine-2-carboxylates exhibit a rare C3-symmetry of the lanthanide coordination polyhedron in the solid state, as confirmed by luminescence spectroscopy and by X-ray crystallography (the three N(∧)N(∧)O ligands...

From Minor Side Phases to Bulk Samples of Lanthanum Oxonitridosilicates: An Investigation with Microfocused Synchrotron Radiation.

Inorganic chemistry

Durach D, Schultz P, Oeckler O, Schnick W.

Inorg Chem. 2016 Apr 04;55(7):3624-9. doi: 10.1021/acs.inorgchem.6b00143. Epub 2016 Mar 15.

Microcrystals of the oxonitridosilicate oxide La(11)Si(13)N(27.636)O(1.046):Ce(3+) were obtained by exploratory high-temperature synthesis starting from La, La(NH2)3, Si(NH)2, BaH2, and CeF3. Owing to the small size of the crystals, microfocused synchrotron radiation was used for structure investigations (space group Cmc21...
