Toward a Data‐Effective Calibration of a Fully Distributed Catchment Water Quality Model

Water Resources Research
Distributed hydrological water quality models are increasingly being used to manage natural resources at the catchment scale but there are no calibration guidelines for selecting the most effective gauging stations.

Synergetic Relay Between Atomic Hydrogen and Chlorine Radicals Enables Efficient Nitrate‐to‐Nitrogen Gas Conversion

Advanced Science, EarlyView.
Using photoelectrochemical (PEC) deep denitrification technology, a novel synergistic reduction‐oxidation process enables efficient conversion of nitrate (NO3−) to nitrogen (N2), while suppressing key intermediate ammonium (NH4+) and toxic nitrite (NO2−) accumulation.

Electrochemical Nitrate Reduction Reaction to Ammonia at Industrial‐Level Current Densities

Advanced Science, EarlyView.
This review starts from the mechanism and theoretical basis of electrochemical nitrate reduction reaction (NO3−RR), and systematically summarizes and discusses the design strategies of industrial‐level current density catalysts. In addition, the progress of industrial‐level NO3−RR‐based electrolyzers, including flow reactor and membrane electrode ...

Enhanced Photocatalytic Wastewater Purification and Bacterial Elimination via Copper Ion Irradiation‐Induced Modification of BiOCl

Advanced Science, EarlyView.
This study presents a copper ion irradiation method to achieve the modification function of BiOCl. By using high‐energy ion beams to introduce impurity ions inside the material, the intrinsic electric field of BiOCl is optimized, promoting the separation of photogenerated carriers and enhancing the photocatalytic activity.

Spatial and inter-annual variability of proto- and metazooplankton during summer around the Kneiss Islands (Tunisia, Central Mediterranean Sea)

Applied Water Science, 2018
We studied the distribution of proto- and metazooplankton coupled with environmental factors in the coast area around Kneiss Islands (Central Mediterranean Sea). Zooplanktonic communities were sampled during summer 2009 and summer 2010 at three stations.

AQUATIC ECOSYSTEM MONITORING REMOTE VEHICLE.

International Journal of Advanced Research, 2018
This paper reports the Underwater Vehicles for Surveillance and Monitoring Aquatic Ecosystem. The acceptable range of pH for aqua environment is between pH 6.0 to pH 8.0. Different problems associated with aquatic ecosystem due to water pollution are increasing pH and temperature due to global warming and decrease of dissolved oxygen.
