New Experimental Tools to Use Noble Gases as Artificial Tracers for Groundwater Flow
Frontiers in Water, 2022 Labeling groundwater by injecting an artificial tracer is a standard and widely used method to study groundwater flow systems. Noble gases dissolved in groundwater are potentially ideal artificial tracers, as they are not subject to biogeochemical ...

Field efficacy evaluation and post-treatment contamination risk assessment of an ultraviolet disinfection and safe storage system. [PDF]
, 2015 Inconsistent use of household water treatment and safe storage (HWTS) systems reduces their potential health benefits. Ultraviolet (UV) disinfection is more convenient than some existing HWTS systems, but it does not provide post-treatment residual ...

Fluorine‐Free Soft Nanocomposites for High‐Speed Liquid Impact Repellence
Advanced Functional Materials, EarlyView.Fluorine‐free soft nanocomposite coatings are developed using silicone oil‐mediated mechanical‐stiffness control, enabling ‘dry’ liquid‐repellent surfaces that resist high‐speed water jet impacts up to ∼60 m/s. By tuning nanoparticle loading and oil content, the coatings also achieve >90% optical transparency, amphiphobicity with impact resistance to ...
