Thermal diffusivity values of molten germanium and silicon were measured by a laser flash method. Simple but useful sample cell systems were developed to keep the molten germanium and silicon shape uniform for a given thickness. In the present experimental condition, it is necessary to consider the effect of not only the radiative heat loss but also the conductive heat loss at the interface bet...

for beneficiation of converter slag, the role of surface phenomena on slag composition was studied. this work includes some experimental data, which were measured for basic oxygen steel (bos) slag in isfahan steel plant. all data were collected on site in the plant. the results support the idea that surface activity plays a major role in converter slag formation. it was also a new finding that ...

Recently, the role of force in cellular processes has become more evident, and now with advances in force spectroscopy, the response of proteins to force can be directly studied. Such studies have found that native proteins are brittle, and thus not very deformable. Here, we examine the mechanical properties of a class of intermediates referred to as the molten globule state. Using optical trap...

alpha-Lactalbumin (alpha-LA) is a two-domain, calcium-binding protein that forms one of the best studied molten globules. We present here amide hydrogen exchange studies of the molten globule formed by human alpha-LA at pH 2 and compare these results with a similar study of the native state at pH 6.3. The most persistent structure in the molten globule is localized in the helical domain, consis...

On the basis of lithium electrolyte mechanism, modified glassy polymers were developed by adding salts to poly(methyl methacrylate) (PMMA). This review summarizes how rheological and mechanical properties PMMA changed introducing various salts: perchlorate (LiClO4), trifluoroacetate (LiCOOCF3), trifluoromethanesulfonate (LiCF3SO3), nonafluorobutanesulfonate (LiC4F9SO3), bromide (LiBr). It was f...

The electrical conductivity of solid and molten Li2S04 —Ag,S0 4 has been measured for different concentration values. Density measurements of molten Li2S04 , Ag2S04 and equimolar (Li, Ag) 2S0 4 show that the system can be considered ideal. The equivalent conductivity of molten (Li, Ag) 2S0 4 can be calculated from the conductivities of the pure salts by assuming that the cations are moving in g...

the hybrid molten/solid in2o3 - 30-48 wt.% bi2o3 oxide materials were studied with respect to their transport properties. the conductivities, oxygen ion transport numbers and oxygen permeation fluxes have been measured by using the four-probe dc, volumetric measurements of the faradaic efficiency and gas flow techniques, respectively. we show that the oxygen permeability of the hybrid molten/so...

The wettability of amorphous and annealing-induced nanocrystalline Fe78B13Si9 ribbons by molten Sn and Bi at 600 K was measured using an improved sessile drop method. The results demonstrate that the structural relaxation and crystallization in the amorphous substrates do not substantially change the wettability with molten Bi because of their invariable physical interaction, but remarkably det...
