Desalination system could produce freshwater that is cheaper than tap water      (via sciencedaily.com)     Original source 

Researchers have designed a new solar desalination system that takes in saltwater and heats it with natural sunlight. The system flushes out accumulated salt, so replacement parts aren't needed often, meaning the system could potentially produce drinking water at a rate and price that is cheaper than tap water.

Sustainable energy for aviation: What are our options?      (via sciencedaily.com) 

Scientists and industry leaders worldwide are looking for answers on how to make aviation sustainable by 2050 and choosing a viable sustainable fuel is a major sticking point. Aerospace engineers took a full inventory of the options to make a data-driven assessment about how they stack up in comparison. He reviewed over 300 research projects from across different sectors, not just aerospace, to synthesize the ideas and draw conclusions to help direct the dialogue about sustainable aviation toward a permanent solution.

Chameleon-inspired coating could cool and warm buildings through the seasons      (via sciencedaily.com) 

As summer turns to fall, many people will be turning off the air conditioning and firing up heaters instead. But traditional heating and cooling systems are energy intensive, and because they typically run on fossil fuels, they aren't sustainable. Now, by mimicking a desert-dwelling chameleon, a team has developed an energy-efficient, cost-effective coating. The material could keep buildings cool in the summers -- or warm in the winters -- without additional energy.

Researchers offer insights into solid-electrolyte interphases in next-gen aqueous potassium-ion batteries      (via sciencedaily.com) 

Aqueous potassium-ion batteries are a promising alternative to lithium-ion batteries owing to their safety and low cost. However, not much is known about the properties of the solid-electrolyte interphases (SEI) that form between the electrode and the aqueous electrolyte. To address this knowledge gap, researchers from Japan have now conducted a study using advanced scanning electrochemical microscopy and operando electrochemical mass spectrometry. Their findings provide a deeper understanding of SEI in next-generation batteries.
