Thermal degradation of aliphatic hyperbranched polyesters and their derivatives
(Elsevier, 2006)
In this study results of thermal degradation of aliphatic hyperbranched polyesters, AHBP, and their derivatives, determined by non-isothermal thermogravimetric analysis in inert atmosphere (N2) are presented. The thermal ...
Sinteza alifatskih hiperrazgranatih poliestara: "pseudo one-step" procedura“
(Belgrade : Serbian Chemical Society, 2008)
Hiperrazgranati polimeri (HBP) i dendrimeri pripadaju klasi dendritskih makromolekula. Za razliku od složene i dugotrajne sinteze dendrimera, HBP se mogu sintetisati korišćenjem jednostavne "one-step" procedure, pri čemu ...
Rheological and thermogravimetric analysis of unmodified and modified aliphatic hyperbranched polyester
(The Society of Physical Chemists of Serbia, 2008)
The influence of the type of end groups on the rheological and thermal properties of aliphatic hyperbranched polyesters (AHBP) was investigated in this work. Unmodified, hydroxy-functional AHBP sample of third pseudo ...
Thermal behaviour of Ag/PMMA nanocomposites synthesized by in situ method
(Institute of Technical Sciences of the Serbian Academy of Sciences and Arts, 2008)
The influence of the surface modified silver nanoparticles (Np), used as a filler, on the thermal properties poly(methylmethacrylate) (PMMA) matrix, synthesized by “in situ” radical polymerization process, was studied. The ...
Termičke karakteristike nanokompozita Ag/PS
(Društvo inženjera plastičara i gumara IPG, Beograd, Srbija, 2008)
U radu je ispitivan uticaj nanočestica srebra (Ag) na termičke karakteristike polimerne matrice polistirena (PS). Ispitivanja su vršena metodom termogravimetrijske analize (TGA) u azotu u zavisnosti od koncentracije ...

containing proteins. Structures of porphyrin containing proteins from the Protein Data Bank (PDB)
Select January 2007, the list ...
Sinteza i karakterizacija nanokompozita Ag/PS
(Belgrade : Serbian Chemical Society, 2008)
Ispitivan je uticaj površinski modifikovanih nanočestica srebra (Ag) na optičke i termičke osobine matrice polistirena (PS). Obojeni transparentni nanokompozitni filmovi, dobijeni direktnim mešanjem nanočestica Ag i ...
Thermal studies of silver- poly(methylmethacrylate) nanocomposites
(The Society of Physical Chemists of Serbia, 2008)
The novel nanocomposite material based on surface-modified silver nanoparticles (Np) with average diameter of 6 nm and poly(methylmethacrylate) (PMMA) matrix was synthesized. The effect of silver loading on the thermal ...
The influence of heat treatment and finishing on the mechanical properties of laminar composites
(Savez inženjera metalurgije Jugoslavije- Yugoslav Association of Metallurgical Engineers, 2002)
