Disordered peptide chains in an α-C-based coarse-grained model [PDF]

open access: yesPhysical Chemistry Chemical Physics, 2018, 20, 19057-19070, 2018
We construct a one-bead-per-residue coarse-grained dynamical model to describe intrinsically disordered proteins at significantly longer timescales than in the all-atom models. In this model, inter-residue contacts form and disappear during the course of the time evolution.

Divanillin-based aromatic amines: synthesis and application as curing agents for bio-based epoxy thermosets [PDF]

open access: yesFrontiers in Chemistry, Frontiers, 2019, 7, 2019
New bio-based diamines were successfully synthesized from vanillin and fully characterized. These amines, methylated divanillylamine (MDVA) and 3,4-dimethoxydianiline (DMAN), were then used as curing agent with epoxy monomers. Epoxy thermosets obtained from these new bio-based amines exhibited promising thermomechanical properties in terms of glass ...

IMG2SMI: Translating Molecular Structure Images to Simplified Molecular-input Line-entry System [PDF]

open access: yesarXiv, 2021
Like many scientific fields, new chemistry literature has grown at a staggering pace, with thousands of papers released every month. A large portion of chemistry literature focuses on new molecules and reactions between molecules. Most vital information is conveyed through 2-D images of molecules, representing the underlying molecules or reactions ...
