In this work, a simple route for the synthesis of surfactant-free immobilized palladium nanoparticles (Pd NPs) and their use as effective nanocatalysts for metal hydride decomposition is described. A mixture of ethanol : water was used as the reducing agent. Ethanol was added in a large excess to reduce the ionic Pd and stabilize the obtained Pd NPs. Ethanol is adsorbed on the surface of Pd all...

The ethanol extract of Gynura procumbens showed virucidal and antireplicative actions against herpes simplex virus HSV-1 and HSV-2. It was further chromatographed on MCI gel CHP20P column giving the extract fractions F1 (water), F2 (water-methanol) F3 (methanol), and F4 (ethyl acetate). All but F1 had virucidal action against both viral types. We reported here the active compounds from F2 and F...

Abstract Equilibrium mole fraction solubility of salicylic acid in nine aqueous-ethanolic mixtures, as well neat water and ethanol, was determined at seven temperatures from T = (293.15 to 323.15) K. Salicylic these mixtures adequately correlated with well-known correlation/prediction methods based on Jouyban-Acree model. Apparent thermodynamic quantities, i.e. Gibbs energy, enthalpy, entropy, ...

Weisinger, R. S., J. R. Blair-West, P. Burns, and D. A. Denton. Intracerebroventricular infusion of angiotensin II increases water and ethanol intake in rats. Am. J. Physiol. 277 (Regulatory Integrative Comp. Physiol. 46): R162–R172, 1999.—The influence of prolonged ingestion of ethanol on stimulation of water or ethanol intake by intracerebroventricular infusion of ANG II was evaluated in rats...

Aquaporin (Aqp) embedded membranes have become a topic of recent research due to the superior selectivity of Aqp to water and its acceptable flux. Most researchers have utilized Aqp membranes for water purification purposes such as reverse and forward osmosis desalination of sea and brackish water and wastewater treatment. This paper investigated the permeation of aqueous ethanol across commerc...

Hypericaceae herb contains biologically active compounds, flavonoids (1.5–5%), naphthodianthrons, phloroglucins, tannins (10-13%), essential oil (0.1–0.33%) and other compounds. In accordance with the patent RU 2,067,452 C1, St. John's wort extract is obtained using a solvent system acetone-70% ethanol – 30% ethanol. extracted acetone. The raw materials remaining after extraction are dried 70% ...
