Bond Memory in Dynamically Determined Stereoselectivity
Journal of the American Chemical Society, 2019 The carboborative ring contraction of cyclohexenes exhibits an abnormal selectivity pattern in which a formally concerted double migration gives rise to predominant but not exclusive inversion products. In dynamic trajectories, the inversion and retention products are formed from the same transition state, and the trajectories accurately account for ...

Social coordination dynamics: Measuring human bonding [PDF]
Social Neuroscience, 2008 Spontaneous social coordination has been extensively described in natural settings but so far no controlled methodological approaches have been employed that systematically advance investigations into the possible self-organized nature of bond formation and dissolution between humans.

Are polar liquids less simple?
, 2012 Strong correlation between equilibrium fluctuations of the potential energy, U, and the virial, W, is a characteristic of a liquid that implies the presence of certain dynamic properties, such as density scaling of the relaxation times and isochronal ...

Dynamic Covalent Synthesis of Crystalline Porous Graphitic Frameworks [PDF]
, 2020 Porous graphitic framework (PGF) is a two-dimensional (2D) material that has emerging energy applications. An archetype contains stacked 2D layers, the structure of which features a fully annulated aromatic skeleton with embedded heteroatoms and periodic

Dynamic strength of molecular adhesion bonds
Biophysical Journal, 1997 In biology, molecular linkages at, within, and beneath cell interfaces arise mainly from weak noncovalent interactions. These bonds will fail under any level of pulling force if held for sufficient time. Thus, when tested with ultrasensitive force probes, we expect cohesive material strength and strength of adhesion at interfaces to be time- and ...

Photocapture of dynamic hydrogen‐bonded assemblies [PDF]
International Journal of Photoenergy, 2004 Recent advances in the continuing study of [2+2] photodimerization reactions in supramolecular, non‐covalent systems are presented. The covalent photocapture of small dynamic assemblies which are formed using weak hydrogen‐bonding interactions between two different complementary units, barbiturates and melamines, is discussed.
