Study of Silicon Cantilevers by the Photoacoustic Elastic Bending Method
(Springer/Plenum Publishers, New York, 2017)
Rectangular silicon cantilevers are studied by the photoacoustic (PA) elastic bending method. Experimental signals versus modulation frequency of the excitation optical beam are measured and analyzed in a frequency range ...
Investigation of Micromechanical Structures by Photoacoustic Elastic Bending Method
(Springer/Plenum Publishers, New York, 2012)
Photoacoustic (PA) and photothermal (PT) science and technology extensively developed new methods for the investigation of micro (nano)-mechanical structures. PA and PT effects can be important also as driven mechanisms ...
Further guaianolides from Amphoricarpos neumayeri ssp murbeckii from Montenegro
(Verlag Z Naturforsch, Tubingen, 2006)
The aerial parts of Amphoricarpos neumayeri ssp. murbeckii afforded eleven guaianolides with the same relative (1 alpha H,4 beta H,5 alpha H, 7 alpha H) configuration of the basic skeleton. All of them contained a CH2OX ...
The effects of centrally applied ghrelin on appetite and metabolic parameters during aging
(Inst Materials Physics, 2014)
The main purpose of this study was to evaluate specifically, ingestive behavior and bloodborne indicators of metabolic status, after daily intracerebroventricular (ICV) ghrelin injections, in rats of different ages. Four ...
Gas Separation Properties of the Dense Polymer-Zeolite Powder Composite Membranes
(Japan Inst Metals, Sendai, 2016)
The natural balance in the Earth's atmosphere is significantly influenced by the human emission of the combustion products, mainly carbon dioxide. Therefore, strong efforts are directed in the direction of the reduction ...
Synthesis and performance of polymer based magnetic composite sensing element
(Inst Materials Physics, 2015)
The commercial multi-mode optical fiber was coated with magnetic composite material prepared using Nd-Fe-B permanent magnet powder dispersed in poly (ethylene-co-vinyl acetate)-EVA. Characterization of microstructure, ...
The possibility of application of zeolyte powders for the construction of membranes for carbon dioxide separation / Mogućnost primene zeolitnih prahova za konstrukciju membrana za izdvajanje ugljen-dioksida
(Association of the Chemical Engineers of Serbia, 2015)
The aim of this study was to construct a polymer-based mixed matrix membrane that could be used for waste gases treatment. Therefore, high permeability for the carbon dioxide and low permeability for other gases commonly ...
GC-MS-based metabolomics for the detection of adulteration in oregano samples / Метаболомика заснована на гасној хроматографији–масеној спектрометрији за детекцију кривотворења узорака оригана.
(Serbian Chemical Society, 2021)
Oregano is one of the most used culinary herb and it is often adulterated with cheaper plants. In this study, GC–MS was used for identification and quantification of metabolites from 104 samples of oregano (Origanum ...
Thermal solid-state Z/E isomerization of 2-alkylidene-4-oxothiazolidines: Effects of non-covalent interactions / Termalna Z/E izomerizacija 2-alkiliden-4-oksotiazolidina u čvrstom stanju - uticaj nekovalentnih interakcija
(Serbian Chemical Soc, Belgrade, 2011)
Configurational isomerization of stereo-defined 5-substituted and unsubstituted 2-alkylidene-4-oxothiazolidines (1) in the solid state, giving the Z/E mixtures in various ratios, was investigated by 1H-NMR spectroscopy, ...
Thermal diffusivity of NTC lasers obtained by photoacoustic technique
(Emerald, 2004)
The thermal diffusivity of thick film NTC layers based on a metal oxide powder mixture was measured at room temperature by the photoacoustic (PA) technique. The powder mixture was composed of MnO (60 percent), CoO (32 ...
