A discovery six years ago took the condensed-matter physics world by storm: Ultra-thin carbon stacked in two slightly askew layers became a superconductor, and changing the twist angle between layers could toggle their electrical properties. The landmark 2018 paper describing “magic-angle graphene superlattices” launched a new field called “twistronics,” and the first author was then-MIT graduate student and recent Harvard Junior Fellow Yuan Cao.

Together with Harvard physicists Amir Yacoby, Eric Mazur, and others, Cao and colleagues have built on that foundational work, smoothing a path for more twistronics science by inventing an easier way to twist and study many types of materials.

A new paper in Nature describes the team’s fingernail-sized machine that can twist thin materials at will, replacing the need to fabricate twisted devices one by one. Thin, 2D materials with properties that can be studied and manipulated easily have immense implications for higher-performance transistors, optical devices such as solar cells, and quantum computers, among other things.

“We have demonstrated that high-performance and environmentally sustainable lithium-ion batteries are not only possible, but also within reach.” Scientists convert waste from solar panels into advanced battery technology — and it could solve major issues with clean energy first appeared on The Cool Down.

An energy-rich future is within reach.

Experts have created a ‘miracle material’ that will be the end of conventional solar panels: 60 times more energy and unexpected performance.

Researchers at SLAC have made groundbreaking strides in understanding the photoelectric effect, initially described by Einstein.

They’ve developed a technique using attosecond X-ray pulses to measure electron-emission delays, revealing discrepancies in existing theories by showing larger-than-expected delays. Their method provides a new tool to study electron-electron interactions, which are fundamental to many technologies, including semiconductors and solar cells.

New Photoelectric Effect Insights

Chinese solar PV giant Trina Solar has successfully begun commercial operations at a new agri-voltaic solar project in Japan that combines solar modules with a yam crop that thrives in the shade.

The agrivoltaic project is only small – just 2.4 MW – and is located in the city of Fukuchiyama in Japan’s northern Kyoto Prefecture, but is a demonstration of the new way of thinking about the use of solar projects and existing farmland.

The Fukuchiyama project is paired with the cultivation of the Japanese yam, also known as ebi-imo, a crop native to the region which thrives in shade.

Since 2014, solar capacity at K-12 schools has more than quadrupled across the US, according to a new report from clean energy nonprofit Generation180.

The “Brighter Future: A Study of Solar on K-12 Schools” report highlights that over 6.2 million students – more than 1 in 9 – now attend schools powered by solar. In 2023 alone, more than 800 schools added solar panels, meaning that at least one school went solar every single day during the 2022–23 school year.

“The benefits of solar energy are now reaching a broad range of schools across the country, including those in under-resourced communities that stand to gain the most from the cost savings and educational opportunities that solar technology provides. We want all schools and communities, regardless of their size, geography, or wealth, to have access to affordable, clean energy,” says Tish Tablan, the report’s lead author and senior director of Generation180’s Electrify Our Schools Program.

Summary: Researchers developed a brain-inspired AI technique using neural networks to model the challenging quantum states of molecules, crucial for technologies like solar panels and photocatalyst.

This new approach significantly improves accuracy, enabling better prediction of molecular behaviors during energy transitions. By enhancing our understanding of molecular excited states, this research could revolutionize material prototyping and chemical synthesis.
