Poster presented at the 4th Serbian Congress for Microscopy, Belgrade, Serbia, 2010, October 11-12, 201

Optical far infrared properties of FeS2

In this paper are presented the far-infrared reflectivity spectra for a cleaved FeS 2 sample measured at roam temperature and at 77 K

Optical far infrared properties of PtSb2

Far infrared reflection spectra measured at room temperature were used to investigate vibrational properties of PtSb2 single crystals. The experimental results were analyzed using a dielectric function taking into account the existence of plasmonionised impurity-phonon interactions. Together with strong coupling three infrared active lattice modes at about 143, 187 and 202 cm-1 were observed. These results were discussed with respect to calculated literature vibrational frequencies. Electrical properties of single crystal PtSb2 were also measured at room temperature

Far infrared properties of iron doped single crystal PbTe

Far infrared reflectivity spectra of single crystal PbTe samples doped with 0.2 at% Fe were measured in the temperature range between 10 K and 300 K. These spectra show very sharp and narrow dips below 120 cm-1. The experimental data were numerically analyzed using a fitting procedure based on the plasmon-phonon interaction model. Two local modes were observed. The first one was noted between 130 cm-1 and 170 cm-1 depending on the temperature and the second more frequency stable one was noted at about 230 cm-1

Analysis of early-stage sintering mechanisms of mechanically activated BaTiO3

Prah barijum-titanata je mehanički aktiviran u planetarnom mlinu sa kuglicama 60 i 120 minuta. Neizotermsko sinterovanje neaktiviranog i aktiviranih uzoraka proučeno je u dilatometru u temperaturskom intervalu od sobne do 1380oS sa tri različite brzine zagrevanja (10, 20 i 30oS/min). Mehanizmi ranih stadijuma sinterovanja su analizirani za sva tri tipa uzoraka i uočene su značajne razlike između neaktiviranih i mehanički aktiviranih uzoraka.Barium-titanate powder was mechanically activated in a planetary-ball mill for 60 and 120 minutes. Non-isothermal sintering of non-activated and activated powder samples was investigated using a dilatometer in the temperature interval from room to 1380oC with three different heating rates (10, 20 and 30oC/min). Early-stage sintering mechanisms for all three types of samples were analyzed, showing significant differences between the non-activated and mechanically activated samples

Structural and electrical properties of ferroelectric poly(vinylidene fluoride) and mechanically activated ZnO nanoparticle composite films

The influence of the mechanical activation of ZnO nanoparticle fillers on the structural and electrical properties of the matrix of poly(vinylidenefluoride)-ZnO (PVDF-ZnO) films was investigated. Transmission electron microscopy and scanning electron microscopy analyses showed that mechanical activation in a high energy planetary ball mill reduces the size of ZnO particles. X-ray diffraction and Raman spectroscopy revealed that PVDF crystallized predominantly as the gamma-phase. Non-activated ZnO filler reduces the degree of the crystallinity of the matrix and promotes crystallization of alpha-phase of PVDF in the film, while the fillers activated for 5 and 10 min induce crystallization of beta-phase, indicating that mechanical activation of the filler can be used as a general method for fabrication of PVDF composites with increased content of piezoelectric beta-phase crystals. Dielectric spectroscopy measurements show that polymer composite with the high content of beta-phase (with ZnO filler activated for 5 min) exhibits the highest value of dielectric permittivity in 150-400 K range of temperatures. Kinetic analysis shows combined effects of increased surface area and increased concentration of surface defects on the interactions between polymer chains and activated nanoparticles

Istraživanje organizacionih nauka u periodu postmoderne

Emergence of industrial society raises a number of important questions for researchers and organizational sciences. Existing theories of organizations (related to industrial engineering and business systems) are characterized by fragmentation and an absolute relativism. This position is a result of the continuous displacement of gravity between the organization processes and institutions and on the other hand, the interaction of man and organizations. Therefore, proper guidance can be difficult for other organizational science. The setting of this question and the search for answers has a stake in the philosophy of science. By accepting the facts in the life situations (dualism of determinism and phenomenology) is the basis of the philosophy of facticity in the science on business organization. Problems of the organization are present in all areas of human activity. This fact determines the issue of demarcation of organizational and other sciences. Determine the structure and abstraction some of organizational science, and special areas of research organizations in the social systems is a step that allows the intensification of research in the future.Nastajanje postindustrijskog društva postavlja brojna i značajna pitanja istraživačima organizacionih nauka. Postojeće teorije organizacija (koje se odnose na organizaciju preduzeća, odnosno poslovnih sistema) karakteriše fragmentarnost i apsolutni relativizam. Ovakav pristup ima rezultat u neprekidnom izmeštanju težišta između organizacije procesa i institucija i sa druge strane, interakcije čoveka i organizacija. Zato odgovarajući putokaz teško može biti za ostale organizacione nauke. Postavka ovog pitanja i traganje za odgovorom ima oslonac u filozofiji nauka. Prihvatanjem činjenica u okviru životnih situacija (dualizma determinizma i fenomenologije) je osnov filozofije fakticiteta u Nauci o organizaciji poslovanja. Problemi organizacije prisutni su u svim područjima ljudskog delovanja. Ova činjenica određuje pitanje razgraničenja organizacionih sa drugim naukama. Određivanje strukture i apstrahovanja pojedinih organizacionih nauka, odnosno posebnih područja istraživanja organizacije u društvenim sistemima predstavlja iskorak koji omogućava intenziviranje istraživanja u narednom periodu

Far infrared properties of PbTe doped with Hg

Single crystal samples of PbTe doped with Hg were grown using the Bridgman method. Far infrared reflectivity spectra were measured at room temperature for samples with 0.5 at. % Hg; 0.9 at. % Hg and 1.4 at. % Hg. The plasma frequency decreased when PbTe was doped with Hg and it was lowest for the PbTe sample doped with 0.5 at. % Hg. The values of the determined optical free carrier mobility increased and was the highest for PbTe doped with 0.5 at. % Hg
