The effect of the pause-to-pulse ratio on the morphology of metal powder particles electrodeposited by square-wave pulsating overpotential
(Switzerland : Springer Nature, 1991)
It is well known that the deposition conditions such as
bath composition, hydrodynamic regime, temperature,
current density, exhibit a strong effect on the grain size
and the morphology of electrodeposited metal ...
Oxidative hydrolysis and acid-catalyzed rearrangement of steroidal isoxazolidines
(Elsevier, 1991)
Treatment of steroidal isoxazolidines 3a, 3b and 5b with N-methylhydroxylamine hydrochloride in boiling ethanol-pyridine (1:1) solution results in elimination of the CH3NH2fragment, affording products of oxidative hydrolysis ...
Oxygen reduction on iron-IV. The reduction of hydrogen peroxide as the intermediate in oxygen reduction reaction in alkaline solutions
(Elsevier, 1991)
The kinetics of hydrogen peroxide reduction were studied on iron in borate buffered and unbuffered solutions of pH ranging from 8.6 to 13.8, with and without the presence of chloride ions. A rotating disk electrode was ...
Depolarization end point can glassy carbon electrodes: Microscale coulometry of thioglycollic acid
(Wiley, 1991)
An externally unpolarized twin couple of glassy carbon electrodes, undergoing different pretreatments, and connected to nothing but a recorder, was engaged for simple and fast end‐point detection of electrometric titrations ...
Isothermal vapor phase epitaxy of (Hg,Cd) Te from Te-rich Hg1-yTey source(Article)
(Elsevier, 1991)
The method of isothermal vapor phase epitaxy (ISOVPE) of Hg1-xCdxTe layers with fixed surface composition is presented. The epitaxial growth was performed from a Te-rich Hg1-yTey (y > 0.5) liquid source, in an open tube, ...
The electro-oxidation of glycerol on the gold(100)-oriented single-crystal surface and poly crystalline surface in 0.1 M NaOH
(Elsevier, 1991)
Studies of chemical and electrochemical reactions at well-defined surfaces provide additional data on surface reactivity and guidelines for the understanding and design of catalytic materials. In this work, the oxidation ...
Electrodeposition of silver powder by pulsating and reversing currents
(Springer Nature Switzerland AG 2020, 1991)
The effect of the shape of the current wave and frequency in silver deposition by pulsating and reversing currents on the morphology of powder particles were investigated. The possibility of obtaining particles with different ...
ALSV investigation of the phase composition of electrolytic Cu + Sn alloys
(Elsevier, 1991)
Anodic linear sweep voltammograms (ALSVs) have been recorded for thin layers of Cu + Sn alloys electrochemically deposited on graphite from a pyrophosphate bath. Three characteristic peaks were found. The first peak, ...
Hexaene H-85, a hexaene macrolide complex
(Switzerland : Springer Nature, 1991)
The hexaene macrolide antibiotics constitute the smallest group of the polyenes (12 ~ 15). Mediocidin, endomycin, hexaene H-85 and hexafungin each have a significant tetraene spectrum in addition to a hexaene spectrum ...
Single-particle settling velocity through liquid fluidized beds
(Elsevier, 1991)
Single-particle settling velocities through waterfluidized
beds have been studied experimentally using
a standard fluidtzation column 40 mm in diameter.
All the particles used were spherical. The combinations
of ...
