The presence of defects in cold mercerizing of cotton goods led to the creation of a new method, called hot mercerizing in which caustic soda solution is used at a high temperature. Hot mercerizing is successfully used in cotton blended with some other fibers. In cotton/polyester blend fabrics, this treatment serves a dual purpose: subjectively, it imparts a silklike soft handle to the po...

The use of group 1 metal alkoxides as additives to activate s-block organometallics is an established phenomenon in polar organometallic chemistry. Typified by the Lochmann–Schlosser superbase, these reagents have proved be exceptionally powerful bases for deprotonative metallation organic substrates. However, despite their long-standing importance synthesis, nature this activating effect remai...

At the past, damaged tissue was removed from the body of patients. But now tissue regeneration using scaffolds and implants are used to repair the damaged tissue and organs. Besides of the mechanical properties of metallic biomaterials, they suffer from bioinertness. Using some surface treatment techniques, the bioactivity and also corrosion resistance of titanium implants could be improved. In...

The adiabatic description of molecular electronic states is based on potential energy surfaces, defined by the motion of the electrons, on which the slower nuclear motions (vibrations and rotations) occur. However, this model breaks down when relativistic effects such as the coupling between the electron spin and its orbital angular momentum (spin-orbit coupling) are taken into account. The res...

This paper presents a multi-stimuli responsive cocrystal system with luminescent properties that can be dynamically controlled and demonstrates the mechanism of cocrystals under multiple stimuli (acid/alkali vapor, force, heat). Detailed spectroscopic, computational, structural studies exhibit obvious charge transfer interactions occur in loosely mixed-stacking cocrystals. Such weakened by acid...

the kinetics of catalyst deactivation and coke formation during dehydrogenation of propane over supported pt–based catalysts and, in particular, the effect of alkali metal promoters on catalyst activity and stability were studied. the analysis of propane conversion data showed that there is an optimum level of alkali metal promoter loading for both catalyst activity and stability.a model based ...
