The Role of Torsional Dynamics on Hole and Exciton Stabilization in π‐Stacked Assemblies: Design of Rigid Torsionomers of a Cofacial Bifluorene [PDF]

open access: yes, 2018
Exciton and charge delocalization across π‐stacked assemblies is of importance in biological systems and functional polymeric materials. To examine the requirements for exciton and hole stabilization, cofacial bifluorene (F2) torsionomers were designed ...

Structure-guided protein design of fluoroacetate dehalogenase for kinetic resolution of rac-2-bromobutyric acid

open access: yesGreen Synthesis and Catalysis, 2020
R-2-Bromobutyric acid is a very important intermediate for the synthesis of agrochemicals and pharmaceuticals. Bioresolution of rac-2-bromobutyric acid (rac-2-BBA) provides a promising process for R-2-bromobutyric acid (R-2-BBA) production.

Thermochemistry of Alane Complexes for Hydrogen Storage: A Theoretical and Experimental Comparison [PDF]

open access: yes, 2011
Knowledge of the relative stabilities of alane (AlH3) complexes with electron donors is essential for identifying hydrogen storage materials for vehicular applications that can be regenerated by off-board methods; however, almost no thermodynamic data ...

Full three-dimensional morphology evolution of amorphous thin films for atomic layer deposition

open access: yesAIP Advances, 2018
We introduce a Monte Carlo model based on random deposition and diffusion limited aggregation in order to study the morphological evolution of deposition of nanofilm, which is difficult to carry out by the experimental methods.

Evidence for the weak steric hindrance scenario in the supercooled-state reorientational dynamics

open access: yes, 2005
We use molecular-dynamics computer simulations to study the translational and reorientational dynamics of a glass-forming liquid of dumbbells. For sufficiently elongated molecules the standard strong steric hindrance scenario for the rotational dynamics ...

"Breakthrough" osmosis and unusually high power densities in Pressure-Retarded Osmosis in non-ideally semi-permeable supported membranes [PDF]

open access: yes, 2017
Osmosis is the movement of solvent across a membrane induced by a solute-concentration gradient. It is very important for cell biology. Recently, it has started finding technological applications in the emerging processes of Forward Osmosis and Pressure ...
