Science Alert September 7, 2022 Current and potential energetically passive procedures for improving atmospheric water harvesting (AWH) capabilities involve different strategies and dedicated materials. In this paper researchers in France have reviewed the advantages and limitations of different AWH strategies from the perspective of morphology and wettability optimization, substrate cooling, and sorbent assistance. They have demonstrated various applications based on advanced AWH technologies. They proposed a prospective concept of multifunctional water vapor harvesting panel based on promising cooling material, inspired by silicon-based solar energy panels providing a brief outlook of its advantages and challenges…read more.

Jiggly Jell-O to make powerful new hydrogen fuel catalyst
Science Daily December 15, 2018 An international team of researchers (USA – MIT, Lawrence Berkeley National Laboratory, UC Berkeley, US Army, China) used gelatin hydrogel as a scaffold to coordinate metal ions (Mo5+, W6+, Co2+), resulting in ultrathin‐film morphologies of diverse TMC sheets. Among these materials, the Mo2C–Co hybrid provides excellent hydrogen evolution reaction (HER) efficiency. Such performance makes Mo2C–Co a viable noble‐metal‐free catalyst for the HER and is competitive with the standard platinum on carbon support. This template‐assisted, self‐assembling, scalable, and low‐cost manufacturing process presents a new tactic to construct low‐dimensional TMCs with applications in various clean‐energy‐related fields…read more.

Liquid battery could lead to flexible energy storage
Phys.org August 14, 2018 Researchers in the UK have developed a ‘hybrid-electric-hydrogen’ flow battery, based upon the design of a nanoscale battery that can store energy, releasing the power on demand as electric power or hydrogen gas that can be used as fuel. When a concentrated liquid containing the nano-molecules is made, the amount of energy it can store increases by almost 10 times. Electric cars could be charged in seconds, as the material is a pumpable liquid. This could mean that the battery of an electric car could be “recharged” in roughly the same length of time as petrol […]
