Electrocatalytic hydrodechlorination (ECH) has been proposed as a potential technology for the effective degradation of organochlorine contaminants. In this study, nanoscale Pd/TiC catalyst with low resistance was dip-coated onto Ti, aiming to fabricate stable Pd/TiC/Ti electrode with enhanced ECH reactivity for efficient dechlorination. Electrochemical techniques indicated that Pd/TiC/Ti electrode

Manufacturing, processing, use, and disposal of nanoclay-enabled composites potentially lead to the release of nanoclay particles from the polymer matrix in which they are embedded; however, exposures to airborne particles are poorly understood. The present study was conducted to characterize airborne particles released during sanding of nanoclay-enabled thermoplastic composites. Two types of nanoclay

Metal-organic frameworks (MOFs) are well known for their versatile applications in diverse fields (e.g., gas adsorption, water purification, sensing, drug delivery, and catalysis). The basic properties of most MOFs (e.g., morphology and structure) are, however, known to be affected sensitively if exposed to moisture/water. In light of this instability, it is necessary to conduct a comprehensive assessment

Filtration products containing silver nanoparticles (Ag-NPs) have been used for water purification to provide drinking water for humans. However, it is unclear if differences in water chemistry influence their effectiveness or whether the presence of Ag in the filtrate (drinking water) impacts the gut microbiome. Using water samples differing markedly in chemical properties, we have found that ≥ 99

Adsorption-photocatalysis is a critical technique to meet the global challenges of environmental pollution and energy source shortages. However, scientific knowledge on how the adsorption process influences the subsequent photocatalytic performance is lacking. Here, we first propose a mechanism for understanding the intrinsic structure-performance relationship between phenolic pollutants and nanocage-like

Oxidative stress is accepted as a key mechanism of silver nanoparticles (AgNPs) toxicity in living organisms. Therefore, mechanistic studies related to the impact of AgNPs on the structure and function of antioxidant enzymes at the molecular level are essential for a comprehensive evaluation of their toxicity. By using a combination of spectroscopic, imaging and fractionation techniques we explored

Nitrate and phosphorous were the leading cause of eutrophication and deterioration of water quality worldwide, owing to increasing fossil fuel consumption and use of modern fertilizers. Herein, we introduced an N-doped ordered mesoporous carbon based skeleton with Cu-Pd nanocrystals (Cu-Pd@N-OMC) for electrocatalytic reduction of NO3− to dinitrogen (N2). Laboratory experiments demonstrated high NO3−
