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 ...
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 ...
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)
The aim of this investigation was to define the optimum conditions of obtaining glass fabric - epoxy resin laminar composites with appropriate mechanical properties that satisfy the quality needed for production of printed ...
Synthesis and characterization of crosslinked polyurethanes
(The Society of Physical Chemists of Serbia, 2008)
Two polyurethane samples, crosslinked with aliphatic hyperbranched polyester, were synthesized and examined in this work. The sample PUPDMS-EO was prepared using ethylene oxide-poly(dimethylsiloxane)-ethylene oxide as ...
Revitalization of rotational biological contactors / Revitalizacija rada 'Bio-disk' uređaja
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
Treatment of waste water in rotating biological contactors (RBC) requires knowing technical and technological conditions and understanding of microbiological processes. Deficient knowledge of these processes and operating ...
Dinamičko-mehanička svojstva hibridnih magnetnih kompozitnih materijala sa polimernom matricom / Dynamic mechanical properties of hybrid magnetic composite materials with polymer matrix
(Универзитет у Београду, Технолошко-металуршки факултет, 2009)
Savremena istraživanja u oblasti razvoja magnetnih kompozitnih materijala na bazi Nd-Fe-B legura usmerena su u tri osnovna pravca: povećanje magnetne energije, odnosno optimizacija magnetnih svojstava, poboljšanje otpornosti ...
