This loofah-inspired, sun-driven gel could purify all the water you'll need in a day      (via sciencedaily.com) 

Access to clean water is being strained as the human population increases and contamination impacts freshwater sources. Devices currently in development that clean up dirty water using sunlight can only produce up to a few gallons of water each day. But now, researchers in ACS Central Science report how loofah sponges inspired a sunlight-powered porous hydrogel that could potentially purify enough water to satisfy someone's daily needs -- even when it's cloudy.

Entangled atoms cross quantum network from one lab to another      (via sciencedaily.com) 

Trapped ions have previously only been entangled in one and the same laboratory. Now, teams have entangled two ions over a distance of 230 meters. The nodes of this network were housed in two labs at the Campus Technik to the west of Innsbruck, Austria. The experiment shows that trapped ions are a promising platform for future quantum networks that span cities and eventually continents.

Plasma-Structural Coloring: A new colorful approach to an inkless future      (via sciencedaily.com)     Original source 

New developments for achieving structural coloring through plasma irradiation of graphite can reduce the reliance upon harmful color dyes. Colors achieved by plasma irradiation are completely erasable and can be manipulated using time exposed to the plasma irradiation, intensity of the irradiation and the thickness of the graphite layer applied. The application of plasma-structural coloring aims to lessen the environmental toll typical adverse dyes have and combat them with the technology surrounding structural colors.

Researchers create smaller, cheaper flow batteries for clean energy      (via sciencedaily.com) 

Flow batteries offer a solution. Electrolytes flow through electrochemical cells from storage tanks in this rechargeable battery. The existing flow battery technologies cost more than $200/kilowatt hour and are too expensive for practical application, but engineers have now developed a more compact flow battery cell configuration that reduces the size of the cell by 75%, and correspondingly reduces the size and cost of the entire flow battery. The work could revolutionize how everything from major commercial buildings to residential homes are powered.
