Physical study of nano ribbon, tetragonal bundled and isolated nano tube SiC (7,0) are part of our project in knowing new nano material such a silicon carbide. These studies have been performed by density function theory. Effect of ribboning, tubulating and tetragonal bundling on the physical properties such as stability, structural constants, optical physics, chemical parameters and mag...

In college level chemistry courses, reasoning using molecular and particulate descriptions of matter becomes central to understanding physical and chemical properties. In this study, we used a qualitative approach to analyzing classroom discourse derived from Toulmin’s model of argumentation in order to describe the ways in which students develop particulate-level justifications for claims abou...

Patterns are often formed when particles cluster: Since patterns reflect the connectivity of different types of material, the emergence of patterns affects the physical and chemical properties of systems and shares a close relationship to their macroscopic functions. A radial dendritic pattern (RDP) is observed in many systems such as snow crystals, polymer crystals and biological systems. Alth...

National governments are becoming increasingly aware of the importance of their soil resources and are shaping strategies accordingly. Implicit in any such strategy is that degradation threats and their potential effect on important soil properties and functions are defined and understood. In this paper, we aimed to review the principal degradation threats on important soil properties in the UK...

From the point of view of intermolecular interactions, the cytoplasmic space is more like a crowded party in a house full of furniture than a game of tag in an empty field. Understanding the physical chemical properties of cytoplasm is thus of key importance for understanding cellular function. This article attempts to provide an entrée into the current literature on this subject and offers som...

In the past few decades there has been a hiatus in the momentum of research and discovery of ‘novel’ medicinal compounds. This particular trend in drug development perhaps is augmented due to two vital factors, namely : first, strict empirical and rational approach to drug design ; and secondly, high standards of safety and therapeutic efficacy together with tremendous increased costs of resear...

Meghalaya is a state of the north eastern region which is recognized as a treasure of many valuable minerals. Mining operations were left to the local miners to take up coal mining as cottage industries since most of the coal deposits are small and isolated and were not amenable for scientific mining to be conducted in the organized sector. The study of soil physical properties has been done be...
