Nanotechnology, as dened by the Interagency Subcommittee on Nanoscale Science, Engineering, and Technology (NSET) of the U.S. Federal Ofce of Science and Technology Policy, is “research and technology development at the atomic, molecular or macromolecular levels, in the length scale 2.1 Introduction ..................…
U ovom doktorskom radu su sintetisani i izuĉavani alifatski mulitblok poli(estar etri) sa\nciljem da se razviju novi biodegradabilni polimerni materijali koji istovremeno poseduju\nelastomerna svojstva, kao i laku preradljivost koja je odlika termoplastiĉnih polimera.\nElastiĉna svojstva potiĉu od dugaĉkih amorfnih me…
The purpose of this thesis is to analytically determine marginal error for the selected current transformer. Current transformer has 1500 ampere-turns and sections with primary winding for nominal currents of 50, 75, 100 and 150 A and its nominal secondary winding current is 1 A. Specific measurement methods were used…
To create new polymeric materials with useful properties based on nc-Si: sunscreen films and coatings, photoluminescent and electroluminescent composites (Kumar, 2008; Olkhov et al, 2010; Bagratashvili et al, 2005; Koch, 2009), light-fast dyes (Ischenko et al, 2010), an important synthetic task is to embed these nanop…
Porous silicon (P-Si), composed of silicon nanocrystals (nc-Si) with characteristic dimensions of 1-5 nm, has the property of photosensitization of singlet oxygen – an excited state of molecular oxygen, involved in many important biochemical processes. Photosensitivity of generation is observed both in the atmosphere…
In the current work nickel hydroxide powder was synthesized through the precipitation method by using 0.5 molar sodium hydroxide solution, 1 molar nickel chloride hexahydrate solution and hydrazine hydrate solution. Three different powders were prepared by varying the amount of hydrazine hydrate solution (5 ml, 10 ml…
Abstract Rb2Cu2Sb2S5 (I), Cs2Cu2Sb2S5 (II), and Rb8Cu6As8S19 (III) are prepared by solvothermal reaction of Cu, Sb (or As2S3), S, and Rb2CO3 or Cs2CO3 in molar ratios of 8:8.2:37.5:5.2 for (I), 8:8.2:50:3.1 for (II), and 6.3:6.1:32.2:5.2 for (III) in diaminopropane and 50 wt.% MeOH/H2O (autoclave, 160 °C (145 °C for (…

Abstract Nanocrystals of all four phases of the Cu—Sb—S system are prepared by a colloidal hot‐injection method.
Abstract The title cathode material is synthesized through a sol—gel route by addition of an aqueous solution of NH4VO3, oxalic acid, LiOAc, and NH4H2PO4 in the ratio of 2:3:2:3 to a solution of sodium dodecyl benzene sulfonate in H2O/EtOH.
Abstract Ga(Sbx)N1‐x (x = 0—0.08) layers are synthesized by metal organic chemical vapor deposition on different planar substrates and GaN nanowire substrates using trimethylgallium and trimethylantimonide as feedstock gases and nitrogen as the carrier gas (565—640 °C).
Abstract SrCaSiAl2O7:xEu2+ (x = 0.00—0.05) phosphors are synthesized by solid state reaction of stoichiometric mixtures of SrCO3, CaCO3, Al2O3, and Eu2O3 using an excess of 6 wt.% H3BO3 as a flux (alumina crucible, 15%H2/N2, 1573 K, 8 h).
Abstract The skutterudites CoSb3 and Co4Sb11.5Te0.5 with bcc crystal structure are prepared by high pressure/high temperature reaction of stoichiometric mixtures of the elements (cubic anvil press, 900 K).
