Reactive molecular dynamics simulations investigating ROS-mediated HIV damage from outer gp120 protein to internal capsid protein.

Molecular dynamics (MD) with the ReaxFF force field is used to study the structural damage to HIV capsid protein and gp120 protein mediated by reactive oxygen species (ROS). Our results show that with an increase in ROS concentration, the structures of the HIV capsid protein and gp120 protein are more severely damaged, including dehydrogenation, increase in oxygen-containing groups, helix shortening or destruction, and peptide bond breaking. In particular, we noticed that extraction of H atoms from N atoms by ROS was significantly higher than that from C atoms.

Determination of Key Groups of Coal Spontaneous Combustion and Risk Prediction Based on Ultrasonic Extraction.

In order to accurately investigate the key microstructures in the spontaneous combustion exothermic process of coal, an ultrasonic extraction method was employed to extract the coal, and the complex microscopic groups within it were stripped and studied. On this basis, Fourier transform infrared spectroscopy and differential scanning calorimetry were employed to assess the content of microscopic groups and the exothermic characteristics of the raw and extracted coal samples. The findings indicated that toluene and methanol demonstrated a notable capacity for extracting aromatic and aliphatic hydrocarbon compounds from coal, whereas -methyl pyrrolidone (NMP) and ethylenediamine (EDA) exhibited a pronounced effect on oxygen-containing functional groups and hydroxyl groups.

Shape-responsive host-guest chemistry: metal-free tetracationic porphyrin nonplanarity promoted by clay mineral interactions assessed by theoretical simulations.

Distortions in the porphyrin core from planarity can trigger a unique structure-property relationship, imparting its basicity, chemical stability, redox potential, and excited-state energetics, among other properties. The colour change promoted by such distortion is signed by red shifts in its electronic absorption spectra. The adsorption of guest -substituted free-base porphyrin species onto inorganic hosts, such as clay minerals (layered aluminium or magnesium silicates), is known to further promote colour changes.
