This paper presents a numerical study on the dispersing flammable limits with respect to the initial methane releases at TCH4,0 = -50 and -150 °C in the crosswind of ambient air according to the arrangement of (a) No Tank, (b) Tank I, (c) Tank II, and (d) Tank I and II on the ground. To provide a better physical insight on the dispersion behaviors ...

The degradation of organophosphorous nerve agents is of primary concern due to the severe toxicity of these agents. Based on the active center of organophosphorus hydrolase (OPH), a bimetallic nuclear ligand, (5-vinyl-1,3-phenylene)bis(di(1H-imidazol-2-yl) methanol) (VPIM), was designed and synthesized, which contains four imidazole groups to mimic...

A novel Pd/CNTs-Ni foam composite catalyst was developed for catalytic hydrodechlorination of chlorophenols by using CNTs-Ni foam as support. Characterizations including FESEM, TEM/HRTEM, HAADF-STEM and element mapping revel that the composite catalyst with 2 wt.% Pd loading possesses high porous micro-network structure and high dispersed active Pd...

Urea formaldehyde (UF) resin residues generate many poisonous chemicals during traditional disposal technologies for organic hazardous wastes. In this study, hydrothermal hydrolysis was developed to decompose, remove, and recycle cured UF resin. Under 140 °C and 2 h of hydrothermal process, 20 mL of either 2 M HCl or 30 w.t. % of formaldehyde solut...

Subject to synthetic conditions, covalent organic frameworks (COFs) are usually in powder form. Herein, taking an azine-linked COF as an example, detailed characterizations indicated that accessible aldehyde groups and hydrazine groups (CNNH2, 88 μmol g-1) concurrently existed on its surface. Intrigued by such feature, we have developed an approach...

Polychlorinated dibenzo-p-dioxins (PCDDs), as a group of notorious anthropogenic environmental toxicants, are arguably ubiquitous in nature. In this study, we investigated the photocatalytic reductive dechlorination of 2-chlorodibenzo-p-dioxin (2-CDD) over Pd/g-C3N4 catalysts under UV-vis irradiation. The g-C3N4 and a series of Pd/g-C3N4 catalysts ...

In this study, the chemical modification of bulk beech wood is described along with its utilization as biosorbent for the remediation of copper from water. The material was prepared by esterification using anhydrides, and reaction conditions were optimized to propose a greener process, in particular by reducing the amount of solvent. This modificat...

Road deposited pollutants (build-up) are continuously re-distributed by external factors such as traffic and wind turbulence, influencing stormwater runoff quality. However, current stormwater quality modelling approaches do not account for the re-distribution of pollutants. This undermines the accuracy of stormwater quality predictions, constraini...

Oral exposure is a major route of human bisphenol A (BPA) exposure. However, influence of gastrointestinal tract on BPA metabolism is unavailable. In this study, in vitro simulator of the human intestinal microbial ecosystem (SHIME) was applied to investigate the changes in bioaccessibility and metabolism of BPA in different parts of gastrointestin...
