Asymmetric molecular conversion of compounds having symmetrical structures.

Molecular and Electronic Structures of TiH3X Compounds

Electronic structure calculations, with a triple zeta plus polarization basis set and second-order perturbation theory, are used to predict the molecular and electronic structures for TiH3X compounds, with X = CH3, NH2, OH, SiH3, PHz, and SH. It is found that for the second-period substituents CH3, NHz, and OH the structures are similar to those of the corresponding silicon compounds. On the ot...

Symmetrical reconfiguration of tensegrity structures

In this article we first present a mathematical model which describes the nonlinear dynamics of tensegrity structures. For certain tensegrity structures a particular class of motions, coined symmetrical motions, is defined. The corresponding equations of motion are derived and the conditions under which symmetrical motions occur are established. Reconfiguration procedures through symmetrical mo...

Structures of KcsA in Complex with Symmetrical Quaternary Ammonium Compounds Reveal a Hydrophobic Binding Site

Potassium channels allow for the passive movement of potassium ions across the cell membrane and are instrumental in controlling the membrane potential in all cell types. Quaternary ammonium (QA) compounds block potassium channels and have long been used to study the functional and structural properties of these channels. Here we describe the interaction between three symmetrical hydrophobic QA...
