Structural effects in electrocatalysis: oxygen reduction on platinum low index single-crystal surfaces in perchloric acid solutions
(Elsevier, 1994)
Oxygen reduction has been studied in 0.1 M HClO4 on the platinum low index surfaces, employing a hanging meniscus rotating-disk technique. A special cleaning procedure has been developed to remove impurities from the surface ...
XPS and AES study of mixed layers of RuO2 and IrO2
(Elsevier, 1990)
The surface composition of RuO2+IrO2 mixed oxide layers (1-2 μm thick) deposited on titanium by thermal degradation of the corresponding chlorides in aqueous or isopropanol solutions has been investigated. A surface ...
Electrochemical passivation of iron in NO3-, SO42-, and ClO4- solutions
(American Chemical Society (ACS), 1998)
Electrochemical passivation of iron was studied in NO3-, SO42-, and ClO4- solutions of different pH values. Passivation potential of iron in NO3- and ClO4- was similar for any pH examined, while in SO42- it was more anodic. ...
Conformations in unsymmetrically N-n-propyl-N-substituted 2-phenylacetamides
(Elsevier Science Publishers B.V, 1992)
As a part of a study on the structural characteristics of some new various N-alkyl-N-substituted 2-phenylacetamides the infrared and 1 H N.M.R. spectra were obtained and interpreted. The synthesis of a various N-n-propyl-N-alkyl ...
Steroidal geminal dihydroperoxides and 1,2,4,5-tetraoxanes: Structure determination and their antimalarial activity
(Elsevier, 1996)
Cholestane-derived gem-dihydroperoxides and tetraoxanes were synthesized starting from 5e~- and 5~3-cholestan3-ones by acid-catalyzed addition of hydrogen peroxide to the ketone. They were characterized by IR, NMR, and
mass ...
Coated-wire and composite ion-selective electrodes based on doped poly(pyrrole)
(Royal Society of Chemistry, 1992)
Chemically and electrochemically prepared doped poly(pyrrole) has been evaluated as a membrane component for ion-selective electrodes (ISEs). Two types of ISE were prepared: coated-wire electrodes (CWEs) and classical ISEs ...
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 ...
Surface characterization of oxidized activated carbon cloth
(Elsevier, 1997)
Cellulose based activated carbon cloth has been oxidized by air, nitric acid, hydrogen peroxide and iron nitrate cristallohydrate melt treatments. Thermogravimetric analysis, selective neutralization, X-ray photoelectron ...
Synthesis, crystal structure, magnetic properties and cyclic voltammetry of the unsymmetric (μ-oxalato)-[N,N′,N″,N‴-tetrakis-(2-pyridylmethyl)-1,4,8, 11-tetraazacyclotetra-decane]dicobalt(II) perchlorate trihydrate
(Taylor and Francis, 1999)
A new dinuclear cobalt(II) complex, [Co2(ox)tpmc](ClO4)2 3H2O, (tpmc = N, N′, N″, N″′-tetrakis(2-pyridylmethyl)-1, 4, 8, 11-tetraazacyclotetradecane, ox2 -oxalate ion), has been synthesized and its crystal structure solved ...
Electrochemical indication of surface reconstruction of (NO), (311) and (111) gold faces in alkaline solutions
(Elsevier, 1993)
The specific adsorption of OH- anion and the changes in the surface atomic structures of (100), (311) and (111) gold faces with charge density are discussed on the basis of cyclic voltammograms and differential capacity-potential ...
