Anisotropy in Thermal and Electronic Properties of Single Crystal GeSe2 Obtained by the Photoacoustic Method
(The Japan Society of Applied Physics, 1998)
Anisotropy in the thermal and electronic properties for two directions of a thermal wave propagation in GeSe2 single crystal was investigated using the photoacoustic frequency transmission technique. First, the electric ...
A photoacoustic investigation of transport properties and thermal diffusivity of InSb single crystals
(Elsevier, 1996)
Thermal and electronic transport properties of low-doped single crystal InSb were determined for the first time and analyzed using a photoacoustic frequency heat transmission technique. The thermal diffusivity, excess ...
Effect of sulfur oxides on surface state and carbon monoxide oxidation activity of CuxZnl-xCr204 mixed oxides
(Elsevier B.V., 1994)
The effect of mixed sulfur oxides pretreatment on the surface state and carbon monoxide oxidation activity of CuxZn1−xCr2O4 mixed oxides, has been investigated using X-ray photoelectron spectroscopy (XPS) and kinetic ...
Multiwavelength fiber-optic temperature sensor for cryogenic to high temperatures
(IEEE, Piscataway, NJ, United States, 1995)
The results of an investigation of an autoreferencing fiber-optic temperature sensor based on a CdTe single crystal are presented. A method for extending the working temperature range is proposed. A special sensor design ...

Synthesis, structure, and reactivity of secosteroids containing a medium‐sized ring. Part 32. Conformations and photochemical reactivity of some unsaturated 5,10‐secosteroidal ketones
(Wiley - VCH Verlag GmbH & Co, 1991)
UV irradiation of the unsaturated (E)‐5,10‐secosteroidal ketones 1 and 6 results, in addition to (E/Z)‐isomerization, in an intramolecular Pateino‐Büchi reaction and, in the case of 1, in transannular cyclization (along ...
13,14-Seco-steroids: A New Type of Modified Steroids Containing a Nine-Membered Ring
(Wiley, 1999)
Oxidations of 14α‐hydroxy‐5α‐cholestan‐3β‐yl acetate (5) with lead tetraacetate under thermal or photolytic conditions or in the presence of iodine proceed mainly by fragmentation of the C(13)−C(14) bond to give as the ...
Сидеритични прослојци у понту околине Неготина
(Geoinstitut, 1993)
Prilikom izdvajanja formacija u neogenu Srbije, duž Save i Dunava (Krstić i dr., 1992) postavilo se pitanje proslojaka sa karbonatom. U vezi sa tim konsultovani su A. Antonović, D.B. Milovanović i druge kolege. Prihvaćena ...
Opening of the Macrocyclic Ring in 5,10:8,9‐Disecosteroids ( = Steroklastanes)
(Weinheim : Wiley-VCH Verlag GmbH & Co., 1992)
Catalytic hydrogenation of the Δ3‐unsaturated (9R,10 R)‐ and (9S,10 S)‐epoxyenol lactones 3a, b., and 4a, b., respectively, affords, in addition to the expected saturated epoxylactones 5a, b and 7a, b, also open‐chain ...
