Faster thin film devices for energy storage and electronics      (via sciencedaily.com) 

An international research team reported the first realization of single-crystalline T-Nb2O5 thin films having two-dimensional (2D) vertical ionic transport channels, which results in a fast and colossal insulator-metal transition via Li ion intercalation through the 2D channels.

Cracking in lithium-ion batteries speeds up electric vehicle charging      (via sciencedaily.com) 

Rather than being solely detrimental, cracks in the positive electrode of lithium-ion batteries reduce battery charge time, research shows. This runs counter to the view of many electric vehicle manufacturers, who try to minimize cracking because it decreases battery longevity.

Energy-storing supercapacitor from cement, water, black carbon      (via sciencedaily.com) 

Engineers have created a 'supercapacitor' made of ancient, abundant materials, that can store large amounts of energy. Made of just cement, water, and carbon black (which resembles powdered charcoal), the device could form the basis for inexpensive systems that store intermittently renewable energy, such as solar or wind energy.

Aluminum materials show promising performance for safer, cheaper, more powerful batteries      (via sciencedaily.com) 

Researchers are using aluminum foil to create batteries with higher energy density and greater stability. The team's new battery system could enable electric vehicles to run longer on a single charge and would be cheaper to manufacture -- all while having a positive impact on the environment.

Understanding the many different ways animals are evolving in response to fire could help conservation efforts      (via sciencedaily.com)     Original source 

In our modern era of larger, more destructive, and longer-lasting fires -- called the Pyrocene -- plants and animals are evolving quickly to survive. By synthesizing the wide body of research about rapid animal evolution in response to fire, a multidisciplinary team of ecology experts hopes to leverage what we already know to help foster evolution-informed conservation plans. In this way, they suggest, we can try to harness the ways in which fire impacts animals to protect vulnerable species -- working with evolution instead of against it.

Dry manufacturing process offers path to cleaner, more affordable high-energy EV batteries      (via sciencedaily.com) 

Early experiments have revealed significant benefits to a dry battery manufacturing process. This eliminates the use of toxic solvents while showing promise for delivering a battery that is durable, less weighed down by inactive elements and able to maintain high energy storage capacity after use. Such improvements could boost wider EV adoption, helping to reduce carbon emissions and achieve U.S. climate goals.

Hidden cameras spot wildlife returning home after 2018 megafire      (via sciencedaily.com)     Original source 

Researchers analyzed more than 500,000 motion-sensor camera trap images taken at a Northern California reserve in the years before and after the Mendocino Complex Fire to understand how the blaze impacted small- and medium-sized mammals. The study is one of the first to compare wildlife observations made before and after a megafire, and is also one of a limited number of studies to focus on the impacts of megafires on California's oak woodlands.

What causes mudslides and floods after wildfires? Hint: It's not what scientists thought      (via sciencedaily.com)     Original source 

Scientists once assumed that flooding and mudslides after wildfires were linked to the waxy coating that builds up on charred soil, preventing water absorption. Researchers found that water flow came from absorbed water in both burnt and unburnt areas, suggesting that water was, in fact, being absorbed into burnt ground. The discovery provides valuable insights into where and when potential flooding and mudslides may occur and how landscapes recover after a wildfire.
