systematic studies on the vapor-liquid equilibria (vle) and conductometric properties of aqueous solutions of model surface-active ionic liquid 1-dodecyl-3-methylimidazolium bromide ([c12mim]br) are performed in the absence and presence of a large series of electrolytes in order to achieve a deeper understanding about the molecular mechanism behind the specific salt effect on the aggregation be...

The removal of indium ions from aqueous solution was carried out by electrocoagulation in batch mode using an iron electrode. Various operating parameters that could potentially affect the removal efficiency were investigated, including the current density, pH variation, supporting electrolyte, initial concentration, and temperature. The optimum current density, supporting electrolyte concentra...

Various two-dimensional (2D) materials have recently attracted great attention owing to their unique properties and wide application potential in electronics, catalysis, energy storage, and conversion. However, large-scale production of ultrathin sheets and functional nanosheets remains a scientific and engineering challenge. Here we demonstrate an efficient approach for large-scale production ...

Models that accurately predict solid–solute phase equilibria in aqueous electrolyte solutions are of mounting importance for numerous industrial processes, especially those operating at high temperatures, pressures, and concentrations. The incorporation of such electrolyte models into process simulators is in great demand. This communication will focus on thermodynamically consistent models tha...

In the pursuit of environmentally friendly energy storage, aqueous organic redox flow batteries (AORFBs) that use naphthalene diimide hold promise for successful application. present article, two different diimides (NDI) are studied as negative electrolyte materials pH-neutral organic/organometallic batteries. The molecules, one core-unsubstituted NDI (2H-NDI) and core-dimethylamino substituted...

Abstract Aqueous Zn-ion battery (AZIB) has become an attractive technology because of its unique features low cost, high safety and the eco-friendliness. MnO2 is model cathode material for AZIB since first report on reversible Zn-MnO2 battery, but recent studies have unveiled different charge storage mechanisms. Due to revamping electrochemistry redesigning electrolyte interface, there tremendo...

Small neutral organic compounds have traditionally the role of markers in electrophoresis, as they are expected to have zero electrophoretic mobility in external electric fields. The background electrolyte contains, however, ions which have unequal affinities to the neutral molecules, which in turn results in their mobilization. In this study we focused on two electrophoretic markers thiourea a...

Nanoporous carbons with high surface area are achieved through direct carbonization of a commercially available zeolitic imidazolate framework (ZIF-8) without any additional carbon sources. The resultant nanoporous carbons exhibit high electrochemical capacitances in an acidic aqueous electrolyte.

The phase inversion technique was used to produce polyaniline (PAn) actuators with different geometries that cannot be obtained by PAn cast from N-methyl-2-pyrrolidinone (NMP) solution in a conventional way. PAn was cast and coagulated in a water bath forming films and tubes with or without a platinum (Pt) wire helix as an interconnect. PAn was doped with hydrochloric solution (HCl, 1 M) (PAn/H...

1. Propylene oxide reacts with DNA in aqueous buffer solution at about neutral pH to yield two principal products, identified as 7-(2-hydroxypropyl)guanine and 3-(2-hydroxypropyl)adenine, which hydrolyse out of the alkylated DNA at neutral pH values at 37 degrees C. 2. These products were obtained in quantity by reactions between propylene oxide and guanosine or adenine respectively. 3. The rea...
