Molecular simulation is becoming an important tool for both understanding polymeric structures and predicting their physical and mechanical properties. In this study, temperature ramped molecular dynamics simulations are used to predict two physical properties (i.e., glass transition temperature and thermal degradation temperature) of a previously synthesised and published telechelic benzoxazin...

Results of laboratory tests on specimens produced from subsoil studies were evaluated tocharacterize geotechnical properties of Tabriz Marl. It was concluded that, Tabriz Marl may be considered as a high liquid limit silt or clay (MH & CH). Range of changes of index, physical and mechanical properties of the Tabriz Marl are comparatively vast. Correlation between these properties has been intro...

rice bran is a major by-product of the rice milling process that contains high amounts of fiber, proteins, fats, vitamins, minerals as well as antioxidants and hence can be utilized in enriching food products. the main aim followed in this study was to determine the effects of rice bran of variable particle sizes (53, 125 and 210 µm) and its quantity (0, 5, 10, 15 and 20%) on the quality of bat...

this paper presents a survey on soil pb concentration around sepahanshahr town located in vicinity of isfahan. due to the lack of regulation and environmental education and awareness, sepahanshahr is now a rapid growing residential area suffering from the considerable consequences of poorly regulated mining activities operating in its vicinity. the aim of this study is to explore the spatial st...

the aim of this study was to explore the minimum amount of urea formaldehyde (uf) resin content and optimum particleboard density while maintaining boards’ quality to reduce production costs. board density at three levels (520, 620 and 720 kg m-3) and resin content (6, 7 and 8%) were variable parameters. stepwise multivariate linear regression models were used to evaluate the influence of board...

Effects were studied of 200 ppm silver and copper nano-suspensions, with size range from 20 to 80 nm, on the hardness of particleboards produced at an industrial scale at the Iran-Choob Factory, Iran. Metal nano-suspensions were added to the mat at two levels of 100 and 150 milli-liters/kg dry weight wood particles, and the results were compared with those of the control panels. Results showed ...

The majority of studies on high-entropy alloys are focused on their phase, microstructure, and mechanical properties. However, the physical properties of these materials are also encouraging. This paper provides a brief overview of the physical properties of high-entropy alloys. Emphasis is laid on magnetic, electrical, and thermal properties.
