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 ...
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 ...
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 ...
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 ...
The influence of milling conditions on the properties of powder of intermetallic compound SmCo5 / Uticaj uslova mlevenja na svojstva intermetalnog jedinjenja SmCo5
(Kiev, Ukraine : Nauka dumka, 1996)
The dependence of magnetic properties of sintered magnetic materials, demands the quantification of the milling conditions. In this paper the part of the results of the investigation of the phase of milling of SmCo5 powder ...
Characteristics of an avalanche photodiode with a spherical contact surface
(IOP Publishing, 1997)
The work presents an analysis of an avalanche photodiode (APD) with a spherical contact surface. We calculated the dependence of the avalanche multiplication and noise parameters on the incident light wavelength. Multiplication ...
Boron and phosphorus doped glassy carbon: I. Surface properties
(Elsevier, 1997)
The effects of boron and phosphorus incorporation in phenolic resin precursor on the surface properties of glassy carbon (GC) have been studied. Characterization of the surface properties using X-ray photoelectron spectroscopy ...
Electrochemical and Surface Characterization of pH Sensor Based on Bisulfate-Doped Poly(pyrrole)
(Wiley, 1997)
Pyrrole was electrochemically polymerized on glassy carbon support in NaHSO4 solutions under different conditions (method applied, concentration of monomer, concentration of the main solution, thickness of the film). These ...
13C N.M.R. spectra of some 5-substituted-3-isopropyl-6-methyl uracils
(Elsevier Science Publishers B.V., Amsterdam, 1990)
13C n.m.r. spectra of some 5-substituted-3-isopropyl-6-methyl uracils were determined in deuterated dimethyl sulfoxide (d6 - DMSO). The substituents are : H, Cl, Br, J, NO2, NH2, N(CH3)2, C6H5, C6H4-NO2-p and C6H4-NH2-p. ...
Oxidation of d-glucose on single-crystal platinum electrodes: A mechanistic study
(Elsevier, 1992)
Reaction kinetics of glucose oxidation on single-crystal platinum electrodes has a pronounced structure sensitivity. Quasi-steady-state measurements show Tafel slopes of 120 mV per decade for Pt(111), but 60 mV per decade ...
