In the title hydrated salt, C15H16NO2 (+)·C6H4BrO3S(-)·H2O, the cation exists in an E conformation with respect to the ethenyl bond and is almost planar, with a dihedral angle of 2.62 (12)° between the planes of the pyridinium and benzene rings. The meth-oxy substituent deviates slightly from the plane of its attached benzene ring [Cmeth-yl-O-C-C torsion angle = -11.6 (6)°]. In the crystal, the cations, anion and water mol-ecules are linked together into chains along [010] by O-H⋯O hydrogen bonds and weak C-H⋯O inter-actions. There is a short Br⋯O contact [3.029 (2) Å]. The crystal structure also features C-H⋯π inter-actions involving the benzene ring of the anion.

Organophosphate pesticides (OPs) are widely used in agricultural fields and can inhibit the activity of human acetylcholinesterase (hAChE) by covalently binding to serine at the enzyme's active site. However, the molecular recognition mechanisms beyond their covalent binding remain unclear. This study employed molecular docking along with molecular dynamics simulations (MD) to investigate four representative OPs, Phosphamidon, Monocrotophos, Dichlorvos, and Trichlorfon, as well as two potential alternatives Magnolol (MAG) and Honokiol (HON), to understand the conformational change of hAChE and its molecular recognition mechanism.

Polycyclic aromatic hydrocarbons (PAHs) are a carcinogenic compound comprised of benzene ring(s). They occur naturally. However, the occurrence of anthropogenic PAHs (originates from human activities and man-made structures) may contribute to water pollution, risking the public health and aquatic life.

Adsorbed natural gas (ANG) storage is emerging as a promising alternative to traditional compressed and liquefied storage methods. However, its onboard application is restricted by low volumetric methane storage capacity. Flexible porous adsorbents offer a potential solution, as their dense structures and unique gate-opening effects are well-suited to enhance volumetric capacity under high pressures.

Accurate prediction of polymer properties using molecular dynamics (MD) simulations requires a properly relaxed starting structure. Polymer models built from scratch by specialized algorithms (self-avoiding random walk, Monte Carlo, etc.) are far from relaxed and, moreover, often possess a large number of structural defects: close contacts between atoms, wrong bond distances, voids, unfavorable molecular conformations or packing, etc.
