the zero-divisor graph of a commutative ring r with respect to nilpotent elements is a simple undirected graph $gamma_n^*(r)$ with vertex set z_n(r)*, and two vertices x and y are adjacent if and only if xy is nilpotent and xy is nonzero, where z_n(r)={x in r: xy is nilpotent, for some y in r^*}. in this paper, we investigate the basic properties of $gamma_n^*(r)$. we discuss when it will be eu...

CuSCN as HTL is used in inorganic planar carbon electrode-based Sb 2 S 3 solar cells resulting a higher PCE (1.95%) compared to Au (PCE = 1.75%). Also, this device architecture enables semitransparent cell 1.67%, AVT 27.6%).

Cell migration is fundamental in both animal morphogenesis and disease. The migration of individual cells is relatively well-studied; however, in vivo, cells often remain joined by cell-cell junctions and migrate in cohesive groups. How such groups of cells coordinate their migration is poorly understood. The planar polarity pathway coordinates the polarity of non-migrating cells in epithelial ...

A two-dimensional CFD model of a planar solid oxide fuel cell (SOFC) has been developed.This model can predict the performance of SOFC at various operating and design conditions.The effect of Knudsen diffusion is accounted in the porous electrode (backing) and reaction zonelayers. The mathematical model solves conservation of electrons and ions and conservation ofspecies. The model is formulate...

Abstract The generation of high-quality human pluripotent stem cells and their derivatives requires growth surfaces imitating the natural micro-environment. Stiff plastic with protein coatings are not an optimal cell niche adjustable needed to meet cell-specific requirements. Alginate hydrogels versatile biomaterials in processes since they can be integrated all fundament workflows only as plan...
