Solvent quality and solvent polarity in polypeptides

open access: yesPhysical Chemistry Chemical Physics, 2023
Synthetic polymers assume a compact/extended conformation in a poor/good solvent. Proteins, formed by both hydrophobic and polar moieties fold in water but not in apolar solvents. This difference can be rationalized and quantified by calculating the solvation free energy.

Dispersion and Stabilization of Alkylated 2D MXene in Nonpolar Solvents and Their Pseudocapacitive Behavior

open access: yesCell Reports Physical Science, 2020
Summary: To date, MXene dispersions have been mostly limited to polar solvents. Here, we show that when the lithium cations present between MXene multilayers after etching are exchanged with di(hydrogenated tallow)benzyl methyl ammonium chloride (DHT ...
