Three diprotic ionic liquids (PILs) containing bis(2-hydroxyethyl) ammonium cations and citrate (DCi), lactate (DL), or salycilate (DSa) hydroxy/carboxylate anions were studied as lubricants for Ti6Al4V–sapphire contact. At room temperature, the neat PILs are non-Newtonian fluids, which show up to a 70% friction coefficient reduction with respect water. New aqueous developed using 1 wt.% additi...

A series of heterocycles was synthesized by the reaction of α,β -unsaturated ketones of benzopyrans or coumarins with various nucleophiles in aqueous medium bearing two points of diversity. Compared to an identical library generated by conventional parallel synthesis, a microwaveassisted procedure dramatically decreased reaction times from hours to minutes, and yields of products and intermedia...

Glucosides are non-ionic surfactants formed by the condensation of fatty acids with glucose (1). They have cleansing and emulsifying properties, and are used in shampoos and soaps, as well as in leave-on products such as lotions, and sunscreen agents. They are completely biodegradable, making them ecofriendly. Although contact allergies to glucosides have been reported, they are uncommon (2–6)....

The biosorption of hexavalent chromium from aqueous solutions by Opuntia cladodes and ectodermis from cactus fruits was investigated. Both types of biomass are considered low-cost, natural, and ecofriendly biosorbents. Batch experiments were carried out to determine Cr(VI) biosorption capacity and the efficiency of the biosorption process under different pH, initial Cr(VI) concentration, and so...
