Effect of Precipitation on Air Pollutant Concentration in Seoul, Korea
Asian Journal of Atmospheric Environment, 2014 In this study, long-term rainfall data with irregular spatial distribution in Seoul, Korea, were separated into individual precipitation events by the Inter-event time definition of 6 hours. Precipitation washout of PM10 and NO2 concentrations in the air

Ameliorating Effect of Chloride on Nitrite Toxicity to Freshwater Invertebrates with Different Physiology: a Comparative Study Between Amphipods and Planarians [PDF]
, 2008 High nitrite concentrations in freshwater ecosystems may cause toxicity to aquatic animals. These living organisms can take nitrite up from water through their chloride cells, subsequently suffering oxidation of their respiratory pigments (hemoglobin ...

Advanced Materials, EarlyView.An injectable cold atmospheric plasma‐activated decellularized tumor extracellular matrix hydrogel is introduced as a post‐surgical immunoactivation platform. The engineered gel attracts residual tumor cells and induces immunogenic cell death, reshaping the tumor microenvironment and eliciting systemic antitumor immunity. In combination with checkpoint

Polymorph‐Specific Electronic Transduction in WO3 during Molecular Sensing
Advanced Materials, EarlyView.Metal‐oxide polymorphs with similar surface chemistry can nevertheless exhibit distinct sensing properties. In γ‐ and ε‐WO3, analyte adsorption appears comparable; yet, only ε‐WO3 induces a pronounced lattice electronic perturbation that accommodates charge in sub‐conduction band minimum states.

Advanced Materials, EarlyView.Electrochemical CO2RR is a key technology for converting CO2 into chemicals, but there remains a gap between “laboratory science” and “engineering practice” in current research. This review establishes a multi‐scale research framework, encompassing atomic‐level characterization, microenvironment regulation, external field‐assisted optimization, and AI ...

Advanced Materials, EarlyView.ABSTRACT Piezocatalytic hydrogen evolution enables the conversion of mechanical energy into chemical fuels, but its efficiency is constrained by a trade‐off between piezoelectric polarization and electronic conductivity. Strong piezoelectric polarization is essential for sufficient driving force, yet highly polar materials typically suffer from poor ...
