Anisotropy in Thermal Properties of Single Crystal α Quartz Obtained by the Photoacoustic Method
(The Japan Society for Analytical Chemistry, 2001)
Anisotropy in the thermal properties in α SiO2 single crystals SC cut mode 1 and mode 2 was investigated using the photoacosutic (PA) frequency transmission technique. The PA amplitude and phase diagrams were measured and ...
Thermoelastic and Electronic Deformation Components of Photoacoustic Signal in Two-layer System
(The Japan Society for Analytical Chemistry, 2001)
A model was derived in order to study the dependence of the photoacoustic signal on the thermal, elastic and carrier
transport properties of two-layer samples. The various systems were considered: the conductor-semiconductor, ...
Some Thermal and Electronic Transport Properties of YBa2Cu3O7-x Obtained by the Photoacoustic Method
(The Japan Society for Analytical Chemistry, 2001)
The possibility of simultaneous determination of some thermal and transport properties of polycrystalline YBa2Cu3O7-x, using a photoacoustic (PA) method was investigated. Both the amplitude and phase PA signals were measured ...
Investigation of Ion-Modificated Silicon by Photoacoustic Frequency Transmission Technique
(The Japan Society for Analytical Chemistry, 2001)
Thermal, elastic and electronic transport properties of ion-modified silicon samples were investigated by a photoacoustic frequency transmission technique. The experimental photoacoustic data vs. the modulation frequency ...
Evidence of stability of sedimentary organic matter during bacterial desilicification of an oil shale / Dokaz o postojanosti sedimentne organske supstance pri bakterijskoj desilicifikaciji jednog uzorka bituminoznog škriljca
(Serbian Chemical Society, 2001)
Aleksinac oil shale organic matter appeared to remain unchanged, according to elemental, IR, P-GC and P-GC-MS analytical characterization, after exposure to Bacillus circulans-Jordan desilicification for 30 days. These ...
Surface roughness minimum: Ag thin layer deposited on a glass / Minimum površinske hrapavosti: tanki sloj Ag deponovan na staklu
(Belgrade : Serbian Chemical Society, 2001)
In this paper the results of an examination of the surface roughness and morphology dependence of silver thin films up to 100 nm thick deposited on a microscope glass on the deposition rate and on the deposition time are ...
Characterization and corrosion properties of electrodeposited Ni-W alloys / Karakterizacija i korozione karakteristike elektrohemijski taložene legure Ni-W
(Serbian Chemical Society, 2001)
Ni-W alloys electrodeposited from citrate solution consist of three different phases, which are all present in high W-content alloys: a solid solution of W in a Ni matrix; an intermetallic compound Ni4W, as well as another ...
Carbon monoxide oxidation on bimetallic Ru/Au(111) surfaces / Оксидација CO на биметалним Ru/Au(111) површинама
(Belgrade : Serbian Chemical Society, 2001)
The electrochemical deposition of Ru on Au(111) was performed in 0.5 M H2SO4 + 10-4 M RuCl3. The obtained bimetallic Ru/Au(111) surfaces were characterised by cyclic voltammetry and in situ STM in 0.5 M H2SO4. The Ru deposit ...
The effect of the composition of the dispersing medium of oxide sols on the electrocatalytic activity of sol-gel obtained RuO2-TiO2/Ti anodes / Uticaj sastava disperzne sredine oksidnih solova na elektrokatalitičku aktivnost RuO2-TiO2/Ti anoda dobijenih sol-gel postupkom
(Serbian Chemical Society, 2001)
The influence of the addition of methanol, ethanol, 1-propanol and 2-propanol to the dispersing medium of a mixture of RuO2 and TiO2 sols on the electrochemically active surface area for proton exchange, as well as on the ...
A time effect in the early stages of a surface oxidation of a Pt(111) plane in alkaline solution / Vremenski efekat u oksidaciji Pt(111) površine u alkalnoj sredini
(Serbian Chemical Society, 2001)
A time effect in the early stages of surface oxidation of a Pt(111) plane in 0.1 M NaOH solution was studied by examining the reduction parts of the j/E profile recorded after holding the potential for various times at ...
