Reversible mechanical control of molecular conformation. [PDF]
Controlling molecular conformation through macroscopic mechanical stimulus may have applications in chiroptical devices, but achieving this in a 3D material is challenging. Now, a quantitative relationship between stretching of an elastomer and reversible conformational changes of a crosslinked molecule has been established.

CONFORMATIONAL TRANSITIONS IN MOLECULAR SYSTEMS [PDF]
Proteins are the "work horses" in biological systems. In almost all functions specific proteins are involved. They control molecular transport processes, stabilize the cell structure, enzymatically catalyze chemical reactions; others act as molecular motors in the complex machinery of molecular synthetization processes.

Tetrabutylammonium tris(methylsulfanylmethyl)phenylborate [PDF]
In the title molecular salt, C16H36N+·C12H20BS3-, three of the four n-butyl chains show a trans conformation, whereas the fourth has the C—C—C—C torsion angle in a gauche conformation [-77.8 (5)°]. In the crystal, molecules are packed in layers parallel

Theoretical Study of Some Nitrososulfamide Compounds with Antitumor Activity
The lowest-energy conformations of four 2-chloroethylnitrososulfamides were determined using the MM+ molecular mechanics method as implemented in Hyperchem 6.0. Some of the calculated structural parameters, angles and bonds lengths were compared with the

Molecular Actuators in Action: Electron-Transfer-Induced Conformation Transformation in Cofacially Arrayed Polyfluorenes [PDF]
There is much current interest in the design of molecular actuators, which undergo reversible, controlled motion in response to an external stimulus (light, heat, oxidation, etc.).

Conformational Plasticity of HLA-B27 Molecules Correlates Inversely With Efficiency of Negative T Cell Selection [PDF]
The development of autoimmune disorders is incompletely understood. Inefficient thymic T cell selection against self-peptides presented by major histocompatibility antigens (HLA in humans) may contribute to the emergence of auto-reactive effector cells ...

Identifying the protein folding nucleus using molecular dynamics [PDF]
Molecular dynamics simulations of folding in an off-lattice protein model reveal a nucleation scenario, in which a few well-defined contacts are formed with high probability in the transition state ensemble of conformations.

The Rotational Barrier in Ethane: A Molecular Orbital Study
The energy change on each Occupied Molecular Orbital as a function of rotation about the C-C bond in ethane was studied using the B3LYP, mPWB95 functional and MP2 methods with different basis sets.
