Most materials expand when heated. A few, such as water just above freezing, contract. Now, for the first time, physicists have found a material that switches from expanding to contracting in the ...
Scientists have upended long-held assumptions about thermal conductivity, revealing that boron arsenide crystals can conduct heat even better than diamond. Researchers at the University of Houston ...
Mechanical Engineering Professor Alan McGaughey of Carnegie Mellon University recently coordinated the Phonon Olympics, ...
A high-resolution TEM image of the nanoparticles studied in this work. Courtesy: J Belo Most materials expand when they are heated up and contract when cooled down – a phenomenon known as positive ...
Stacking dies introduces layers of complexity driven by multi-physics interactions, which must be addressed at the start of ...
A research team from Penn State has broken a 165-year-old law of thermal radiation with unprecedented strength, setting the stage for more efficient energy harvesting, heat transfer and infrared ...
The polyamorphsim in amorphous materials is one of the most fascinating topics in condensed matter physics. In amorphous metals, the nature of polyamorphic transformation is poorly understood. Here we ...
Report by BC Professor of Physics David Broido and international colleagues confirm high thermal conductivity predicted for isotopically enriched cubic boron nitride Research by Professor of Physics ...
