As the name suggests, most electronic devices today work through the movement of electrons. But materials that can efficiently conduct protons—the nucleus of the hydrogen atom—could be key to a number of important technologies for combating global climate change.

Most proton-conducting inorganic materials available now require undesirably high temperatures to achieve sufficiently high conductivity. However, lower-temperature alternatives could enable a variety of technologies, such as more efficient and durable fuel cells to produce clean electricity from hydrogen, electrolyzers to make clean fuels such as hydrogen for transportation, solid-state proton batteries, and even new kinds of computing devices based on iono-electronic effects.

In order to advance the development of proton conductors, MIT engineers have identified certain traits of materials that give rise to fast proton conduction. Using those traits quantitatively, the team identified a half-dozen new candidates that show promise as fast proton conductors. Simulations suggest these candidates will perform far better than existing materials, although they still need to be conformed experimentally. In addition to uncovering potential new materials, the research also provides a deeper understanding at the atomic level of how such materials work.

WASHINGTON (AP) — On Sunday, the Earth sizzled to the hottest day ever measured by humans, yet another heat record shattered in the past couple of years, according to the European climate service Copernicus Tuesday.

Copernicus’ preliminary data shows that the global average temperature Sunday was 17.09 degrees Celsius (62.76 degrees Fahrenheit), beating the record set just last year on July 6, 2023 by .01 degrees Celsius (.02 degrees Fahrenheit). Both Sunday’s mark and last year’s record obliterate the previous record of 16.8 degrees Celsius (62.24 degrees Fahrenheit), which itself was only a few years old, set in 2016.

Without human-caused climate change, records would be broken nowhere near as frequently, and new cold records would be set as often as hot ones.

The challenges posed by solar and wind generators are real. They are inherently variable, producing electricity only when the sun is shining and the wind is blowing. To ensure reliable energy supplies, grids dominated by renewables need “firming” capacity: back-up technology that can supply electricity on demand.

Some, including the Albanese government, argue gas-fired generators are needed to fill the gap. Others, such as the Coalition, say renewables can’t “keep the lights on” at all and Australia should pursue nuclear energy instead.

But a new way to firm up the world’s electricity grids is fast developing: sodium-ion batteries. This emerging energy storage technology could be a game-changer – enabling our grids to run on 100% renewables.

A study published in Cell Reports Physical Science showcases a novel method for the recycling of unsaturated polymers such as rubber and plastics.

Researchers develop flexible, colorful films made entirely from cellulose, combining the optical properties of nanocrystals with the strength of nanofibers for sustainable electronics.

Lucid says new updates make the Air Pure electric sedan beat Tesla and everybody else when it comes to powertrain efficiency.

This remarkable miniature rotorcraft is so lightweight and efficient that it can lift its own mass given nothing but sunlight. The entire thing weighs about as much as four paperclips, and it can fly all day if the sun’s shining.

Researchers at China’s Beihang University and the Center of Advanced Aero-Engine, have unveiled CouloumbFly, a palm-sized miniature rotorcraft that weighs just 4.21 g (0.15 oz) – yet still boasts a rotor diameter of 20 cm (7.9 in), making it around 600 times lighter than any other comparable small solar-powered drone.
