Static characteristics of metal-insulator-semiconductor-insulator-metal (MISIM) structures-I. Electric field and potential distributions
(Elsevier, 1975)
The static characteristics (potential and electric field distributions) of sandwich structures of a metal 1-insulator 1-nondegenerated semiconductor-insulator 2-metal 2 (M1I1S I2M2)-type are analyzed. A theory is given ...
Far infrared characterization of samarium doped single crystal PbTe
(Bucharest, Romania : National Institute of Research and Development for Optoelectronic, 2004)
Single crystal samples of lead telluride doped with samarium were produced using the
Bridgman method. Far infrared reflectivity spectra in the temperature range 10 K - 300 K are
presented and numerically analyzed using ...

(USA : American Chemical Society, 2022)
The Marchantiophyta (liverworts) are rich sources of phenolic substances, especially cyclic and acyclic bis-bibenzyls, which are rare natural products in the plant kingdom, together with bibenzyls and characteristic ...
Lasersko čišćenje nepoželjne patine nakita / Laser cleaning of unwanted jewelry patina
(Савез Инжењера и техничара Србије, Београд, 2022)
Женска огрлица, филигран са непожељном патином, чишћена је Nd:YAG ласером. Током експеримента варирани су параметри ласера: таласна дужина, флуенца и број импулса, односно време озрачавања. Испитиван је утицај наведених ...
Ecological cleaning of corrosion products on mettalic embroidery textile artefacts by Nd:YAG laser
(Scientific professional society for environmental protection of Serbia-ECOLOGICA, 2015)
A great number of textile objects with metallic embroidery are kept in Ethnographic Museums all over the world. Corrosion is a process that occurs under the external chemical, mechanical and biological influences. The ...
Linear free energy relationships of half-wave reduction potentials of (E)-4-aryl-4-oxo-2-butenoic acids
(Elsevier, 2010)
Half-wave reduction potentials of a set of twelve (E)-4-aryl-4-oxo-2-butenoic acids obtained by direct current polarography in methanol are reported. E1/2 is correlated with Hammett sigma values as well as with values of ...

(2022)
Energy systems of the future should enable transition to clean energy and reduction of CO2 emission. Various options are under consideration and research. One direction of development are photovoltaic, and rechargeable ...
A possible mechanism of formation of flower-like MgO/Mg(OH)2 structures by galvanostatic molten salt electrolysis: The concept of local diffusion fields
(Elsevier, 2019)
The processes of electrodeposition from magnesium nitrate hexahydrate melt by galvanostatic regime of electrolysis
have been analyzed. The structure of the formed particles was examined by X-ray diffraction (XRD),
which ...
Quantifying oxygen vacancies in neodymium and samarium doped ceria from heat capacity measurements
(Elsevier, 2020)
It has been previously reported in the literature that the vacancy concentration in a solid can be estimated using the linear term derived from low temperature heat capacity measurements. This paper investigates how such ...
