Introduction: Zinc is an essential rare element that plays an important role in synaptic plasticity and modulation of the activity of central nervous system and is involved in learning and memory. Increasing zinc intake may protect against conditions associated with zinc deficiency, such as diabetes. Some studies have revealed that zinc deficiency in diabetic subjects is due to hogher excret...

The formation of different complexes in aqueous solutions is an important step in understanding the behavior of zinc chloride in water. The structure of concentrated ZnCl2 solutions is governed by coordination competition of Cl(-) and H2O around Zn(2+). According to the solid-liquid phase diagram, the title compounds were crystallized below room temperature. The structure of ZnCl2·2.5H2O contai...

The composites graphite/ZnO were prepared using calcination method. Zinc chloride (ZnCl2) and sodium carbonate (Na2CO3) were used for synthesis of zinc oxide (ZnO), whereas micromilled and natural graphite were used as the matrix for ZnO nanoparticles growing. During the reaction of ZnCl2 with saturated aqueous solution of Na2CO3 new compound Na2Zn3(CO3)4•(H2O)3 originates. During the calcinati...

Malathion is an organophosphate widely used as an insecticide in agriculture and in public health programs, causing risk to human health. As was recently reported, malathion induces depressant-like behavior and oxidative damage to the brain of rodents. Given the relevance of searching for neuroprotective agents against such damage, this study was therefore undertaken to investigate the neuropro...

Growth assays were conducted with 8-dayold crossbred chicks to evaluate the available choline in 44 and 49% protein soybean meals, and also in whole heat-treated soybeans. A choline-free (experimental basal d i e t ) p r e t e s t diet was imposed from day 5 to 8 posthatching to diminish choline stores. Soybean sources were added at 5 and 10% to the basal diet, and a choline response curve was ...

Thermal decomposition of layered zinc hydroxide double salts provides an interesting alternative synthesis for particles of zinc oxide. Here, we examine the sequence of changes occurring as zinc hydroxide chloride monohydrate (Zn5(OH)8Cl2·H2O) is converted to crystalline ZnO by thermal decomposition. The specific surface area of the resultant ZnO measured by BET was 1.3 m(2) g(-1). A complicati...

The synthesis of furanic derivatives (5-hydroxymethylfurfural (HMF), furfural . . . ) from carbohydrates is of high interest for a wide range of applications. These reactions are carried out in the presence of various solvents, and among them choline chloride can be used. It is a salt that can form a low melting mixture with a carbohydrate (fructose, glucose . . . ) or a deep eutectic mixture w...

Abstract Deep eutectic solvents (DESs) have been considered as novel and economic alternatives to traditional lubricants because of their similar physicochemical performance. In this study, choline chloride (ChCl) DESs were successfully synthesized via hydrogen-bonding networks urea thiourea the hydrogen bond donors (HBDs). The as-synthesized ChCl-urea ChCl-thiourea had excellent thermal stabil...
