Influence of heat treatment on mechanical and sorptional properties of viscose-based nonwovens
(Niscair, 2005)
The influence of heat treatment on sorptional and mechanical properties of viscose: polypropylene (90:10) blend nonwoven fleeces has been studied. It is observed that the heat treatment improves mechanical properties ...
Improvement of the mechanical properties of spark plasma sintered hap bioceramics by decreasing the grain size and by adding multi-walled carbon nanotubes
(International Institute for the Science of Sintering, Beograd, 2013)
Composites based on HAP and oxidized multi-walled carbon nanotubes (o-MWCNT) and monophase HAP materials were processed by spark plasma sintering. Starting from stoichiometric nano-sized HAP powder, monophase bioceramics ...
Poly[(N-isopropylacrylamide)-co-(itaconic acid)] hydrogels with poly(ethylene glycol)
(Wiley, Hoboken, 2010)
The aim of the work reported here was to investigate temperature- and pH-sensitive hydrogels of N-isopropylacrylamide (NIPAM) and itaconic acid (IA) and their semi-interpenetrating polymer networks (semi-IPNs) with varying ...
Effect of the Degree of Conversion on Mechanical Properties and Monomer Elution from Self-, Dual- and Light-Cured Core Composites
(Materials, 2021)
The objective of this work was to measure and correlate the degree of conversion (DC), mechanical properties and monomer elution from self-, dual- and light-cured core composites. Five samples of each of the following ...
Mechanical properties of biomorphic silicon carbide ceramics
(International Institute for the Science of Sintering, Beograd, 2011)
Biomorphous β-SiC ceramics were produced from linden wood by impregnation with tetraethyl orthosilicate (TEOS), followed pyrolysis and high temperature treatment at 1580°C. Six specimen groups included charcoal and five ...
Preparation and properties of low cement castable sintered at different temperatures
(University of Novi Sad, 2009)
The low cement high alumina castable (LCC) studied in this paper was synthesised, cured and then treated at different sintering temperatures. Since any inhomogeneity introduced during the castable preparation can remain ...
Mechanical properties correlation to processing parameters for advanced alumina based refractories
(International Institute for the Science of Sintering, Beograd, 2012)
Alumina based refractories are usually used in metallurgical furnaces and their thermal shock resistance is of great importance. In order to improve thermal shock resistance and mechanical properties of alumina based ...
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 ...
Cavitation resistance of composite polyester resin/basalt powder
(Society for Structural Integrity and Life, Institute for Material Testing, 2019)
The paper presents the results of research on cavitation resistance of the composite based on unsaturated polyester resin and basalt powder, as reinforcement. Basalt powder was obtained by grinding and micronising basaltic ...
Experimental and numerical investigations of the critical values of J-integral for the steel of steam pipelines
(Elsevier Science Bv, Amsterdam, 2018)
Steel grade 14MoV6-3 is a low-carbon microalloyed steel with addition of chromium and molybdenum. This grade is designed mainly for power industry applications, withstanding operating at elevated temperatures.In this paper, ...
