New method can remove dyes from wastewater

North Carolina State University researchers have demonstrated that a synthetic polymer can remove certain dyes from water, and that the polymer can be recovered and reused. The findings offer a new potential method for cleaning ...

Selective membrane may cycle dual-ion batteries closer to reality

Lithium-ion batteries are relatively safe, long-lasting, fast charging and better for the environment than non-rechargeable batteries—right? Not quite. The rocking-chair mechanism that allows for commercial power storage ...

Remote control for plants

Plants have microscopically small pores on the surface of their leaves called stomata. These help plants regulate the influx of carbon dioxide for photosynthesis. They also prevent the loss of too much water and withering ...

Selective concentration of cationic species

Sample pretreatment processes such as concentration or classification are essential to finding trace substances present in a fluid. In scientific communities recently, prolific research is being conducted on sample pretreatment ...

Shining a light on the weird world of dihydrogen phosphate anions

Scientists at UNSW Sydney, together with collaborators from Western Sydney University and The Netherlands, were surprised to find that dihydrogen phosphate anions—vital inorganic ions for cellular activity—bind with other ...
