As semiconductor devices become ever smaller, researchers are exploring two-dimensional materials for potential applications in transistors and optoelectronics. Controlling the flow of electricity and heat through these materials is key to their functionality, but first we need to understand the details of those behaviors at atomic scales. Now, researchers have discovered that electrons play a surprising role in how energy is transferred between layers of 2D semiconductor materials tungsten diselenide and tungsten disulfide.

Researchers at Berkeley Lab have developed a new kind of heating and cooling method that they have named the ionocaloric refrigeration cycle. They hope the technique will someday help phase out refrigerants that contribute to global warming and provide safe, efficient cooling and heating for homes.

In the summer, sea- and bay-breeze circulations are important drivers of the weather in southeastern Texas. This research used machine learning techniques to unpack how these circulations interact with larger-scale weather systems to affect how thunderstorms form in the Houston area. These insights are helping researchers focus their study of aerosol and cloud life cycle, aerosol-cloud interactions, and air quality during the TRACER field campaign in the Houston area in 2021 and 2022.

Researchers are combining experimental, theoretical, and observational data on neutron stars to constrain the equation of state (EOS) and to glean the composition of their interiors. Different techniques probe the EOS at different densities, thereby creating a “density ladder” that aims to connect the various rungs. The findings indicate a possible phase transition in the interior of neutron stars.
