Researchers have developed a method to control the direction of heat flow in crystals. This miniature device could eventually be used to create advanced thermal-management systems in electronic ...

Left: A beam of electrons generates vibrational waves in a crystal lattice that are then reflected by quantum dots. Right: Generated vibrations are more easily reflected by abrupt, sharp interfaces of ...

Light exposure switches heat flow in barium titanate by altering its structure, offering a reversible method for dynamic thermal control in ferroelectric materials. (Nanowerk Spotlight) We can switch ...

Its core working principle can be summarized in two processes: “energy conversion” and “phase change of the medium.” ...

A rare mineral from a 1724 meteorite defies the rules of heat flow, acting like both a crystal and a glass. Thanks to AI and quantum physics, researchers uncovered its bizarre ability to maintain ...

The figure shows the evolution of the microstructure of the melt pool under the influence of the simulated transient temperature field. Nucleated grains are represented in pink-purple plots, while ...
