In this paper, we review some recent work on amorphous materials using current “first principles” electronic structure/molecular dynamics techniques. The main theme of the paper is to emphasize new directions in the use of such ab initio methods. Some of these, being quite new, need development, but we believe have promise for solving new and important kinds of problems in the physics of glassy...
متن کاملMetal-organic framework materials as nano photocatalyst
Photocatalytic degradation of toxic organic compound in water, soil and air by semiconductor catalysts such as TiO2 and ZnO have received much attention over the last two decades. However, the low quantum yield, easy agglomeration and difficult post-separation of these inorganic catalysts limit their application for large-scale applications. Metal-organic frameworks (MOFs) are the latest class ...

متن کاملTriplet Excitons in Organic Materials
The theory of delayed fluorescence produced in an organic material by singlet excitation through an absorbing layer is given. It is shown, that it will be reduced by a factor la.2/ ( la .+ ls) 2 due to the singlet energy transfer to such a layer, where /a the penetration depth of the exciting irradiation and Zs the diffusion lenght of the singlets. Further reduction of delayed fluorescence shou...
متن کاملOrganic photomechanical materials.
Organic molecules can transform photons into Angstrom-scale motions by undergoing photochemical reactions. Ordered media, for example, liquid crystals or molecular crystals, can align these molecular-scale motions to produce motion on much larger (micron to millimeter) length scales. In this Review, we describe the basic principles that underlie organic photomechanical materials, starting with ...
