Crystal engineering π-ways for enhanced charge transport

Charge density analysis for crystal engineering

This review reports on the application of charge density analysis in the field of crystal engineering, which is one of the most growing and productive areas of the entire field of crystallography. While methods to calculate or measure electron density are not discussed in detail, the derived quantities and tools, useful for crystal engineering analyses, are presented and their applications in t...

Towards design strategies for anion–π interactions in crystal engineering

Enhanced Charge Transport in Amorphous Li2O2

The properties of the Li2O2 discharge phase are expected to impact strongly the performance of Li−air batteries. Although both crystalline Li2O2 (c-Li2O2) and amorphous Li2O2 (a-Li2O2) have been reported to form in Li−air cells, little is known regarding possible differences in charge and mass transport within these phases. To reveal these differences, here we predict the properties of a-Li2O2 ...

Search for direct CP violating charge asymmetries in K ± → π ± π + π − and K ± → π ± π 0 π 0 decays

A measurement of the direct CP violating charge asymmetries of the Dalitz plot linear slopes Ag = (g + − g)/(g + g) in K → πππ and K → πππ decays by the NA48/2 experiment at CERN SPS is presented. A new technique of asymmetry measurement involving simultaneous K and K beams and a large data sample collected allowed a result of an unprecedented precision. The charge asymmetries were measured to ...

The synthesis, crystal structure and charge-transport properties of hexacene.

Acenes can be thought of as one-dimensional strips of graphene and they have the potential to be used in the next generation of electronic devices. However, because acenes larger than pentacene have been found to be unstable, it was generally accepted that they would not be particularly useful materials under normal conditions. Here, we show that, by using a physical vapour-transport method, pl...
