The nature of halogen bonding: insights from interacting quantum atoms and source function studies

IUCrJ
A detailed study of the X...N (X = I, Br) halogen bonds in complexes formed by an extended set of substituted pyridines with D—X molecules (D = X, CN) is reported here.

(R)-2-(2-Methoxyphenyl)-2,5-dihydrothiophene-3-carbaldehyde

Acta Crystallographica Section E, 2010
In the title compound, C12H12O2S, the asymmetric unit contains two independent molecules. The chiral C atoms of both molecules were established to be in the R configuration. In both molecules, the 2,5-dihydrothiophene rings adopt S-envelope conformations

Ultracold giant polyatomic Rydberg molecules: coherent control of molecular orientation

, 2010
We predict the existence of a class of ultracold giant molecules formed from trapped ultracold Rydberg atoms and polar molecules. The interaction which leads to the formation of such molecules is the anisotropic charge-dipole interaction ($a/R^2$).

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Di-μ-aqua-bis(μ-pyridazine-4-carboxylato-κ2N:N′)bis[triaqua(pyridazine-4-carboxylato-κ2O,O′)lead(II)] dihydrate

Acta Crystallographica Section E, 2009
The structure of the title compound, [Pb2(C5H3N2O2)4(H2O)6]·2H2O, is composed of dimeric molecules in which two symmetry-related Pb2+ ions are bridged by a pair of two pyridazine-4-carboxylate ligand molecules via both heterocyclic N atoms and ...

Ultracold spin-polarized mixtures of 2Sigma molecules with S-state atoms: Collisional stability and implications for sympathetic cooling

, 2011
The prospects of sympathetic cooling of polar molecules with magnetically co-trapped alkali-metal atoms are generally considered poor due to strongly anisotropic atom-molecule interactions leading to large spin relaxation rates.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

A Molecular Dynamics Study on the Effects of Nanostructural Clearances on Thermal Resistance at a Lennard-Jones Liquid-Solid Interface

Journal of Thermal Science and Technology, 2011
The effects of the surface structures and the surface structural clearances at the nanometer scale on the thermal resistance at a Lennard-Jones liquid-solid interface, as well as the self-diffusion behaviors of liquid molecules, were investigated ...

Optimal conversion of Bose condensed atoms into molecules via a Feshbach resonance

, 2006
In many experiments involving conversion of quantum degenerate atomic gases into molecular dimers via a Feshbach resonance, an external magnetic field is linearly swept from above the resonance to below resonance.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
