Harnessing Cloud Architecture for Crystal Structure Prediction Calculations

Cryst. Growth Des. 2018, 18, 11, 6891-6900

Accurate and rapid crystal structure predictions have the potential to transform the development of new materials, particularly in fields with highly complex molecular structures (such as in drug development). In this work we present a novel cloud-computing crystal structure prediction (CSP) platform with the capability of scheduling hundreds of thousands CPU cores and integrating cutting-edge computational chemistry algorithms.…

Tuning Peptide Self-Assembly by An In-Tether Chiral Center

Sci. Adv. 2018;4: eaar5907

The self-assembly of peptides into ordered nanostructures is important for understanding both peptide molecular interactions and nanotechnological applications. However, because of the complexity and various self-assembling pathways of peptide molecules, design of self-assembling helical pepti…

CHARMM Drude Polarizable Force Field for Glycosidic Linkages Involving Pyranoses and Furanoses

J. Chem. Theory Comput. 2018, 14, 6, 3132-3143

We present an extension of the CHARMM Drude polarizable force field to enable modeling of polysaccharides containing pyranose and furanose monosaccharides. The new force field parameters encompass 1↔2, 1→3, 1→4, and 1→6 pyranose–furanose linkages, 2→1 and 2→…

Proper Balance of Solvent-Solute and Solute-Solute Interactions in the Treatment of the Diffusion of Glucose Using the Drude Polarizable Force Field

Carbohydrate Research, Volume 457, 2018, pp. 41-50

Motivated by underestimation of the diffusion constant of glucose in aqueous solution at high glucose concentrations we performed additional optimization of the Drude polarizable hexopyranose monosaccharide force field. This indicated aggregation of the glucose at higher concentrations, which …
