Nucleation and growth of sodium colloids in NaCl under irradiation: theory and experiment [PDF]

, 2005
A mechanism of radiation-induced emission of Schottky defects from extended defects proposed originally for metals has recently been applied to ionic crystals, where it is based on interactions of excitons with extended defects such as dislocations and ...

The Solar Neutrino Problem - An Update [PDF]

, 1998
The $^8$B solar neutrino flux as measured by Super-Kamiokande is consistent with the $^{37}$Ar production rate in $^{37}$Cl at Homestake. GALLEX and SAGE, continue to observe $^{71}$Ge production rates in $^{71}$Ga that are consistent with the minimal ...

Comparison of chlorine decay models under varying temperature and UV254 for water supply

Results in Engineering
Bulk chlorine decay in water distribution systems is strongly influenced by temperature and organic matter. Higher temperatures accelerate chlorine decay reactions, while organic matter acts as a primary reactive substance.

Self-adaptive amorphous CoOxCly electrocatalyst for sustainable chlorine evolution in acidic brine

Nature Communications, 2023
Electrochemical chlorine evolution reaction is of central importance in the chlor-alkali industry, but the chlorine evolution anode is largely limited by water oxidation side reaction and corrosion-induced performance decay in strong acids.

Application of black-box models based on artificial intelligence for the prediction of chlorine and TTHMs in the trunk network of Bogotá, Colombia

Journal of Hydroinformatics, 2023
The chlorine and total trihalomethane (TTHM) concentrations are sparsely measured in the trunk network of Bogotá, Colombia, which leads to a high uncertainty level at an operational level.

Relationship between chlorine decay and nanobubble application in secondary treated wastewater

Water Science and Technology
There has been numerous research on the uses of treated wastewater that needs chlorine disinfection, but none have looked at the impacts of injecting nanobubbles (NBs) on the decomposition of residual chlorine.

New emission line at ~3.5 keV - observational status, connection with radiatively decaying dark matter and directions for future studies [PDF]

, 2014
Recent works of [1402.2301,1402.4119], claiming the detection of extra emission line with energy ~3.5 keV in X-ray spectra of certain clusters of galaxies and nearby Andromeda galaxy, have raised considerable interest in astrophysics and particle physics

Optimal Site Location for Booster Stations of Chlorine Injection with non-linear Decay Rate in Water Distribution System [PDF]

آب و فاضلاب, 2015
Conventional methods for solving the problem of site location for booster chlorination stations have assumed the use of linear superposition principle for first-order kinetics of chlorine decay in water distribution systems in order to speed up the ...

Decay process of free residual chlorine concentration affected by travel time in water distribution systems

Revista Ambiente & Água, 2022
Chlorination is the most widely used method for disinfecting water for human consumption. While the chlorinated water travels through a distribution system, the concentration of free residual chlorine (FRC) declines depending on the natural water ...

Experimental appraisal and numerical modelling of chlorine demand and decay in a typical drinking water distribution network in South Africa

Ecotoxicology and Environmental Safety
Safe drinking water requires sound monitoring and maintenance of residual chlorine within drinking water distribution networks (DWDNs) to suppress possible microbial regrowth.
