Molybdenum disulfide nanoporous membranes for water desalination
We demonstrate molybdenum disulfide (MoS2) as a nano porous membrane for water desalination. By performing extensive molecular dynamics simulations, we find that a nanopore in a single-layer MoS2 can effectively reject salt ions and allow transport of water at a high rate. More than 88% of ions are …

Characterizing Factors That Influence Intracellular Thiol-Disulfide Equilibrium
<p>Thiol-disulfide balance is critical for the proper functioning of many proteins. Reduced thiol residues can aid in cofactor binding and catalysis, while disulfide bonds are often required for protein folding and stability. Therefore, oxidation of critical cysteine residues can either activate or …

Patterns in the sequence context of protein disulfide bonds
Disulfide bonds play an important role in the structural stability of the proteins that contain them. Yet, little is known about the specificity with which they are formed. To address this, a representative set of disulfide bonds from nonhomologous eukaryotic polypeptides was created. The amino …
