New structure-activity relationship models have been established for predicting dielectric strengths and boiling points of gaseous molecules using the ab initio calculated descriptors, which are combinations of the density-dependent statistical properties of the electrostatic potential surface with molecular polarizability, electronegativity, and hardness. The novel theoretical model is capable of screening and designing new environment-friendly dielectrics as alternatives to sulfur hexafluoride.

The conformational space of a tansmembrane molecule in a DPPC membrane by means of large scale molecular dynamics simulations has been investigated. This molecule consists of different parts with fundamentally different interactions with their environment. The core consists of aromatic rings; the two outer groups in contact with the surrounding water are hydrophilic glycerol groups, while at the center one alkane as well as one perfluoroalkane chain are attached.

Nitric oxide shows a relevant role in many biological processes and ruthenium amine complexes can be used to control its availability. Thus, the influence of two different treatments for relativistic effects (ECP or DKH2) is analyzed with respect to geometric parameters and energies of typical chemical reactions involving this class of complexes. Additionally, several electronic structure methods are evaluated comparatively to the reactions energies from CCSD(T).
- A multipolar approach to the interatomic covalent interaction energy

Interatomic or interfragment covalent energies in real space, as measured by the interacting quantum atoms exchange-correlation energies ( ) are shown to be well-approximated by a multipolar approximation if terms up to the charge–quadrupole interaction are retained (cdq). The cdq approximation improves considerably the performance of the zeroth-order approximation, in which Vxc is equal to the bond order (delocalization index, δAB) over the interatomic distance.
- Gating energetics of a voltage-dependent K+ channel pore domain
Greg Starek, J. Alfredo Freites, Simon Bernèche and Douglas J. Tobias
Version of Record online: 16 FEB 2017 | DOI: 10.1002/jcc.24742
Free energy calculations suggest multiple energetically favorable conformations of the pore domain of KvAP, a voltage gated potassium ion channel. The energetic landscape is influenced by the hydration of the ion conducting pore. The solvation effects revealed here could bridge seemingly contradictory theoretical and experimental results concerning the mechanism and energetics of gating in voltage-gated potassium ion channels.
