Skinnerite Cu3SbS3, which consists of non-toxic and low-cost elements, is a potential thermoelectric material, however, studies on its properties are limited. In this study, the optimal conditions mechanical alloying (MA) hot pressing (HP) for synthesis Cu3SbS3 phase were investigated, evaluated. The MA powder had theoretically predicted cubic skinnerite phase, remained even after HP. Thermal a...

Crystal engineering has recently emerged as a method of choice for the design and the construction of both organic and metal-organic functional materials. Solid-state synthesis, of the most commonly studied aspects of crystal engineering, has been shown to provide access to molecular targets that are hardly obtainable using principles of conventional (i.e. solution-based) organic synthesis. Rea...

objectives: scaling and root planing (srp) is one of the most commonly used procedures during periodontal treatment. the aim of this study was to evaluate the root surface roughness after srp with erbium: yttrium aluminum garnet (er:yag) laser compared to ultrasonic and hand instruments.   materials and methods: in this experimental study, 56 extracted sound single-rooted teeth with moderate le...

background and objectives: bacillus species are attractive industrial organisms due to their rapid growth rates leading to a short fermentation cycle and for their capacity to secrete important enzymes and proteins such as xylanase into the extracellular medium. considering the industrial importance of xylanase, in this current study, bacillus spp. were isolated from different soils and were sc...
