this review reports recent advances in the field of polymer–layered silicate nano composites. thesematerials have attracted both academic and industrial attention because they exhibit dramaticimprovement in properties at very low filler contents. herein, the structure, preparation andproperties of polymer–layered silicate nanocomposites are discussed in general, and finally the effectof clay na...

background and objectives: recently, due to the interest of healthy lifestyle demand for research on novel methods of increasing the shelf-life of food products without the necessity of using preservatives has extended rapidly in the world. ability of nanoemulsions to improve global food quality has attracted great attention in food preservation. this is as a result of a number of attributes pe...

algebraic frames are generalizations of fourier transforms on locally compact abelian groups in the sense that the family of vectors forming the frame are replaced by a family of unbounded linear functionals. the paper studies the indexing measure space of the algebraic frames; as the investigation narrows down to the class of lower semiframes, more relations are revealed between the discret...

durability as continuity of identity and dynamism as changing and adaptability to new conditions are important architectural discussions. this paper aims to define the concepts and positions of durability and dynamism in the architectural structure. it seems that it is important to discuss which relations and components of an architectural structure have more effective roles in supporting ident...

The high pressure behavior of the structural and electronic properties of KC1 is studied with use of the density functional pseudopotential method within local-density approximation. Atzero pressure, the rocksalt phase is found to be lower in energy than CsCl structure. However, we predict a phase transition into CsCI structure at a pressure of about 1.5 GPa. The calculated ground state pro...
