fabrication of ultrafine grained materials by imposing severe plastic deformation for improvement of mechanical and physical properties of metals has been the focus of many researches over the past few years. in this process, a sheet is subjected to repetitive shear deformation conditions by utilizing asymmetrically grooved and flat dies through alternate pressing. in this study, a 2mm thick co...
this article provides an overview on preparation, design, crystal structure and properties of some metal-organic frameworks of carboxylate coordination polymers mixed with pyridine-functionality linkers prepared in our laboratory. the article covers coordination polymers in two- and three-dimensional supramolecular architectures. the reported coordination polymers ex...
