In vitro study of drug loading on polymer‐free oxide films of metallic implants

“…The second peak, at the lower frequency, indicates the presence of a hydroxyl group. The shifting of a phase angle to a negative value after 1 Hz and the absence of the second peak after loading of heparin on amorphous oxide film suggests an interaction between the hydroxyl group and the heparin 35, 36…”

“…The shifting of a phase angle to a negative value after 1 Hz and the absence of the second peak after loading of heparin on amorphous oxide film suggests an interaction between the hydroxyl group and the heparin. 35,36 As stated above, a small quantity of inductance from heparinized EP surface is an indication of a limited interaction between the heparin and the EP surface on the 316LVM stainless steel wire. The lack of inductance for the heparinized PO surface indicates that the formation of a bonding between heparin and a PO surface is impossible.…”

Hydrogen evolution reaction at nickel boride electrodes in aqueous and in aqueous methanolic and ethanolic solutions

“…The hydrogen evolution reaction (HER) is of prime importance in the whole range of electrocatalytic processes and has therefore been one of the most studied cathodic reactions (1)(2)(3)(4)(5). In the recent past, due to its economic and environmental impact, an increased interest in the practical industrial application of low-overvoltage cathode electrolyses has been noted.…”

“…In the recent past, due to its economic and environmental impact, an increased interest in the practical industrial application of low-overvoltage cathode electrolyses has been noted. Hydrogen has also played a major role in synthetic organic chemistry in the well-known catalytic hydrogenation process by which an unsaturated compound R, adsorbed at the surface of a catalyst M, (M(R)), is reduced by the adsorbed hydrogen M(H) (reactions [I]- [4]) (6). 1 ' Author to whom correspondence may be addressed.…”

“…In this process, the hydrogenation reaction (eqs. [2]- [4]) is in competition with hydrogen evolution (reactions [6] and (or) [7] representing the electrochemical and chemical desorption of hydrogen respectively (Scheme 1)) and the efficiency of the ECH is determined by this competition.
