Development and characterization of thermosensitive hydrogels based on poly(N-isopropylacrylamide) and calcium alginate
(Wiley, Hoboken, 2012)
This work refers to the synthesis and characterization of thermosensitive hydrogels based on interpenetrating polymer networks (IPNs) of poly(N-isopropylacrylamide) (PNIPAAm) and calcium alginate in the form of films. The ...
Impact of choice of stabilized hysteresis loop on the end result of investigation of high-strength low-alloy (hsla) steel on low cycle fatigue
(Croatian Metallurgical Soc, Zagreb, 2014)
High strength low-alloy steel under low cycle fatigue at a certain level of strain controlled achieve stabilized condition. During the fatigue loading stabilized hysteresis loop is determined, which typical cycle of ...
Effect of hydroxyapatite spheres, whiskers, and nanoparticles on mechanical properties of a model BisGMA/TEGDMA composite initially and after storage
(Wiley-Blackwell, Hoboken, 2013)
This study investigated the effect of shape, size, and surface modification of hydroxyapatite (HAP) fillers on the degree of conversion (DC) and mechanical properties of a model BisGMA/TEGDMA composite initially and after ...
High strength thermoresponsive semi-IPN hydrogels reinforced with nanoclays
(Wiley Periodicals, Inc., 2012)
Two series of nanoclay reinforced, thermoresponsive hydrogels were prepared, one based on poly(N-isopropylacrylamide) (PNIPA) and the other on semi-interpenetrating networks containing PNIPA and poly(N-vinyl pyrrolidone) ...
Ag+, Cu2+ and Zn2+ doped hydroxyapatite/tricalcium phosphate bioceramics: Influence of doping and sintering technique on mechanical properties
(University of Novi Sad, Faculty of Technology, 2018)
Green hydroxyapatite ceramics were obtained by cold uniaxial and isostatic pressing of hydrothermally synthesized powders, pure hydroxyapatite and hydroxyapatite doped with Ag+, Cu2+ and Zn2+ ions. The ceramics were ...
Structure prediction, high pressure effect and properties investigation of superhard B6O
(IOP Publishing Ltd, Bristol, 2020)
Ab initio data mining approach has been used in order to investigate B6O system and discover new possible modifications, besides experimentally known R-3m (alpha-B6O) structure and theoretically predicted Cmcm (beta-B6O) ...
Identification of low cycle fatigue parameters of high strength low-alloy (hsla) steel at room temperature
(Croatian Metallurgical Soc, Zagreb, 2014)
Low cycle fatigue test was performed in ambient atmosphere at room temperature. cycle loading of material, in case of High strength low-alloy steel, entails modifications of its properties and in this paper is therefore ...
Wash-dry cycle induced changes in low-ordered parts of regenerated cellulosic fibers
(Wiley-Blackwell, Hoboken, 2012)
Three regenerated cellulosic fiber types: lyocell, viscose, and modal were subjected to repetitive wetdry treatments. Simulated treatments showed reorganization of the internal fiber structure which could be determined by ...
Design of halloysite modification for improvement of mechanical properties of the epoxy based nanocomposites
(Polymer Composites, 2021)
In this study, halloysite nanotubes (HNT) were modified by: 3-glycidyloxypropyltrimethoxysilane (GLYMO), 3-aminopropyltrimethoxysilane (APTES), and 2,2-Bis[4-(glycidyloxy) phenyl] propane (DGEBA), and incorporated in the ...
The effect of natural modifiers for starch hydrophobization on performance of composite based on ethylene acrylic acid copolymer
(Wiley, Hoboken, 2021)
As a renewable resource, starch is considered to be fully biodegradable and nonpolluting to the environment but the hygroscopicity of starch is the main disadvantage for wider applicability in the production of a polymer-based ...
