one of the best and the most active ways for surveying thermal behaviour of materials is using differential scanning calorimetry. in this paper, the authors have studied thermal behaviour for schiff base ligand and their synthesized cobalt, nickel complexes. in this method, the sample is opposed to a controlled temperature change and its physical properties. here we studied melting point and tg...

a nanofluid is a dilute liquid suspension of particles with at least one critical dimension smaller than ~100 nm. research works so far suggest that nanofluids offer excellent heat transfer enhancement over conventional base fluids. the enhancement depends on several factors such as particle shape, particle size distribution, volume fraction of nanoparticles, temperature, ph, and thermal conduc...

objective: studies have demonstrates that physical properties of denture base affect patient satisfaction and acceptance. thermal conductivity is among the most important properties of denture base influencing the sense of taste and gingival health. the conventionally used acrylic resin has a low coefficient of thermal conductivity. this study aimed to improve the thermal conductivity of acryli...

bituminous emulsion insulators are types of bituminous emulsions groups composed of different grades of bitumen emulsified in water by bentonite and emulsifiers at 80-90oc. these emulsions are water resistant after drying andtheir physical and mechanical properties are superior in comparison to bitumen properties. iranian climate, because of variety and extreme variations in temperature imposes...

the effects of physical, thermal and mechanical parameters on curing microthermal residual stresses are studied, based on the energy method, to present a theoretical solution for prediction of residual stress felds. a fnite element analysis is developed to compare the theoretical and numerical results together. there is found to be a good agreement between the results of the two methods. howeve...
