By means of in situ IR spectroscopy we investigate the effect of dissolved alkali cations on the electro-oxidation of ethylene glycol on platinum in alkaline media. The results revealed that the increase in the oxidation currents (Li(+) < Na(+) < K(+)) is reflected in the increase in the ratio between carbonate and oxalate produced.

A facile route to prepare catalytically active materials from a galinstan liquid metal alloy is introduced. Sonicating liquid galinstan in alkaline solution or treating it in reducing media results in the creation of solid In/Sn rich microspheres that show catalytic activity toward both potassium ferricyanide and 4-nitrophenol reduction.

Nanoscale metal ring and dot catalyst arrays are printed over large substrate areas using vertically aligned carbon-based stamps with the ring- and dot-shaped tips. The fundamental nature of these ring and dot catalysts is successfully compared by applying them in diverse electrocatalytic reactions in acidic and alkaline media.

In this paper, two novel alkali clearable disperse dyes were synthesized. 4-flourosulfonyl aniline and 2-nitro-4-flourosulfonyl aniline were utilized as the diazo components and 2- naphthol as the coupling component. The DSC, FTIR, 1HNMR and UV-Vis analyses were used to characterize the synthesized intermediates and dyes. The synthesized dyes were used to dye polyester fibers and their dyeing p...
