carbon-boron clathrates as a new class of sp3-bonded

Nanomaterials for Hydrogen Storage Applications: A Review

2008/12/17Another class of materials for hydrogen storage may be clathrates [], which are primarily hydrogen-bonded H 2 O frameworks. Initial studies have indicated that significant amounts of hydrogen molecules can be incorporated into the sII clathrate.

RECENT DEVELOPMENTS IN THE CHEMISTRY OF POLYHEDRAL

carbon atoms present in the icosahedral carboranes bear partial positive charges in the ground state12 and thereby activate the two equivalent boron atoms which are nearest neighbours for nucleophilic attack. The rather general rearrangement of 1,2- to 1,7

CHEMISTRY MASTER: UNIT 4 ( PAGE 3)

For example, when one 2s and three 2p-orbitals of carbon hybridise, there is the formation of four new sp3 hybrid orbitals. Salient features of Hybridisation Hybridisation is a theoretical concept which has been introduced to explain some structural properties such as shapes of molecules or equivalence of bonds, etc. which cannot be explained by simple theories of valency.

In CH 4 carbon is the neutral atom. The electronic configuration of carbon (z = 6) is 1s 2,2s 2,2p 2. It consists of four valence electrons which forms four bond pairs with four hydrogen atoms. Now, the central carbon atom is surrounded by four electron pairs

Engineering covalently bonded 2D layered materials by

Engineering covalently bonded 2D layered materials by self-intercalation Professor Loh Kian Ping's group and researchers at NUS Materials Science and Engineering have fabricated a whole new library of atomically thin two-dimensional (2D) materials, christened "ic-2D", to denote a class of materials based on self-intercalation of native atoms into the gap between the layers of crystals.

1 Introduction

This new book examines the state of the technology arising from these discoveries in relation to other allied materials, such as high-pressure diamond and cubic boron nitride. Most of the potential defense, space, and commercial applications are related to diamond's hardness, but some utilize its other qualities, such as optical and electronic properties.

Classification of structural modifications of carbon,

2013/8/1New schemes have been proposed for the structural classification of carbon phases and nanostructures. These schemes are based on the types of chemical bonds formed in materials and on the number of nearest neighbors with which each atom forms covalent bonds. The classification schemes allow one to describe the already known phases and form the methodological basis for the prediction of new
