A SO3H-functionalized ionic liquid was used as an alternative to conventional inorganic acids in hydroxylamine stabilization, leading to the formation of a novel hydroxylamine ionic liquid salt that exhibits improved thermal stability and reactivity in the one-step, solvent-free synthesis of caprolactam in comparison with hydroxylamine hydrochloride and hydroxylamine sulfate.

Effects of kaolin applicati on were evaluated on water stress in pistachio cv. ‘Ohadi’. This experiment was conducted in one of research sites at the Pistachio Research Institute in Rafsanjan (Kerman province) in . The results show that individual and interaction effects of all treatments were significant on nutrition absorption in leaves, although there was not a steady effect on all the eleme...

In this research modified Kaolin by Cetyltrimethylammonium bromide is used as an adsorbent for the removal of Reactive Blue 21 from aqueous solutions. Response Surface Methodology was used to study the effect of independent variables, such as Reactive Blue 21 dye concentration (20, 40, 60, 80 and 100 mg/L), time (10, 20, 30, 40 and 50), initial pH (2, 4, 6, 8 and 10) and modified Kaolin dosage ...

When Folin and Denis’ described their method for the estimation of non-protein nitrogen in blood, it became possible to make such determinations quickly, accurately, and with the use of only small amounts of blood. The method rapidly came into general use and has proved to be of great service. It has, however, not escaped modification in the interest of increased accuracy and convenience. The p...

BACKGROUND Protease inhibitors, particularly ritonavir, causes significant gastrointestinal disturbances such as nausea, even at low doses. This ritonavir-induced nausea could be related to its oxidative stress in the gut. Alleviation of drug-induced nausea is important in effectively increasing patients' compliance and improving their quality of life. Conventional anti-emetic drugs can only pa...

Nanoparticles can reduce the friction coefficient and present a self-restorative effect MoDTC is important as friction-reducing additive. Both are for improving lubricating performance. In this study, tribological performances of nanoparticles in presence were studied. The chemical synthetic ball-milled selected test samples, evaluated by block-ring rig. Experimental results show that serpentin...

Drought, elevated air temperature, and high evaporative demand are increasingly frequent during summer in grape growing areas like the Mediterranean basin, limiting grapevine productivity and berry quality. The foliar exogenous application of kaolin, a radiation-reflecting inert mineral, has proven effective in mitigating the negative impacts of these abiotic stresses in grapevine and other fru...

Hydrocephalus is a common neurological disease in humans, but a uniform and particularly effective hydrocephalic animal model amenable to proper appraisal and deep study has not yet been established. In this study, we attempted to construct a high-efficiency model of hydrocephalus via intraventricular kaolin injection. Adult male Sprague-Dawley rats were randomly divided into 2 groups: the cont...
