Advances in electrochromic coatings may bring us closer to environmentally friendly ways to keep inside spaces cool. Like eyeglasses that darken to provide sun protection, the optical properties of these transparent films can be tuned with electricity to block out solar heat and light. Now, researchers in ACS Energy Letters report demonstrating a new electrochromic film design based on metal-organic frameworks (MOFs) that quickly and reliably switch from transparent to glare-diminishing green to thermal-insulating red.

Hongbo Xu and colleagues used MOFs in their electrochromic film because of the crystalline substances’ abilities to form thin films with pore sizes that can be customize...

A new study by Brown University researchers may help redefine how scientists map the surface of the Moon, making the process more streamlined and precise than ever before.

Published in the Planetary Science Journal, the research by Brown scholars Benjamin Boatwright and James Head describes enhancements to a mapping technique called shape-from-shading. The technique is used to create detailed models of lunar terrain, outlining craters, ridges, slopes and other surface hazards...

A research team at Stanford’s Wu Tsai Neurosciences Institute has made a major stride in using AI to replicate how the brain organizes sensory information to make sense of the world, opening up new frontiers for virtual neuroscience.

Watch the seconds tick by on a clock and, in visual regions of your brain, neighboring groups of angle-selective neurons will fire in sequence as the second hand sweeps around the clock face. These cells form beautiful “pinwheel” maps, with each segment representing a visual perception of a different angle. Other visual areas of the brain contain maps of more complex and abstract visual features, such as the distinction between images of familiar faces vs. places, which activate distinct neural “neighborhoods.”

The global shift to electric vehicles is gaining momentum, yet the extraction of battery materials has a significant environmental footprint that comes with high costs.

Now, two studies led by McGill University researchers offer hope in the search to manufacture cheaper and greener lithium-ion batteries used in electric vehicles (EVs).

Their findings unlock the potential to produce batteries using more sustainable and less costly metals, known as disordered rock-salt-type (DRX) cathode materials.

In the first study, engineering researchers including lead author Richie Fong, a Ph.D. student in Materials Engineering, focused on cathodes...
