In the title co-crystal, C2H8NO2·C 4H6O6, the gylcine molecule is present in the zwitterion form. In the tartaric acid molecule there is a short intramolecular O - H⋯O contact. In the crystal, the tartaric acid molecules are linked via pairs of O - H⋯O hydrogen bonds, forming inversion dimers. These dimers are linked via a number of O - H⋯O and N - H⋯O hydrogen bonds involving the two components, forming a three-dimensional network. Source

Nano-crystalline Gadolinium Titanate (Gd2Ti2O 7) powder was successfully synthesized by "Single Step Molten Salt Technique". LiCl-KCl eutectic mixture was used as a molten medium for the reaction. The duration of the synthesis was 10 h. Stoichiometric proportion of the reactants were mixed in an (LiCl-KCl) eutectic medium and treated at 750 C in an electrical resistance furnace. Single phase Gadolinium Titanate compound was obtained by the thermal process. The synthesized powders were characterized using XRD, FT-IR, UV, EDAX and XPS analyses. The morphology of the powder was examined using SEM and TEM techniques. From the above studies, it has been concluded that pure crystalline Gadolinium Titanate powders can be synthesized via low temperature molten salt process. © 2013 Elsevier Ltd and Techna Group S.r.l.

The removal of cadmium from aqueous solution was carried out by electrocoagulation using magnesium as anode and stainless steel as cathode. Various operating parameters on the removal efficiency of cadmium were investigated, such as initial cadmium ion concentration, initial pH, current density and temperature. The optimum removal efficiency of 98.6% was achieved at a current density of 0.2 A dm-2 at a pH of 7.0. The experimental data were tested against different adsorption isotherm models for describing the electrocoagulation process. The adsorption of cadmium preferably fitting the Langmuir adsorption isotherm suggests monolayer coverage of adsorbed molecules. First and second-order rate equations were applied to study adsorption kinetics. The adsorption process follows second order kinetics model with good correlation. Temperature studies showed that adsorption was endothermic and spontaneous in nature. © 2010 Springer Science+Business Media B.V. Source

A straightforward synthesis of -keto amides by coupling primary amines with aryl dibromoethanones under oxidative amidation conditions has been developed. The -keto amides were then subjected to heterocyclodehydration reaction under Bischler-Napieralski conditions followed by aromatization with DBU provided 1-benzoyl isoquinolines in a two-stage process. Utilizing this methodology, isoquinoline alkaloids such as thalmicrinone, papavaraldine, and pulcheotine A were synthesized in excellent yields. © Georg Thieme Verlag Stuttgart · New York. Source
