RUAG Space Produces Thermal Insulation for Launchers

RUAG Space has kicked off a new product line, thermal insulation for launch vehicles. “We have more than 25 years of experience in high-quality thermal insulation for satellites. Building upon this knowledge we enter a new market segment and produce thermal insulation

Researchers Introduce Novel Heat Transport Theory

NCCR MARVEL researchers have developed a novel microscopic theory that is able to describe heat transport in very general ways, and applies equally well to ordered or disordered materials such as crystals or glasses and to anything in between. This is not

Two Types of Cooling Require Different Designs

Thermoelectric devices can be used to remove heat from hot objects, like computer components or batteries. However, these so-called Peltier coolers are typically optimized for keeping a cold object cold, which is a different thermodynamics problem. Researchers have now developed a new

Modulating the Thermal Conductivity in Hexagonal Boron Nitride

Hexagonal boron nitride (h-BN) is a technologically important layered material used as a dielectric spacer, encapsulant, ultraviolet laser emitter, and hyperbolic material in electronic and photonic applications1,2,3. More recently, h-BN has attracted attention for thermal management of electronics as theoretical calculations4predicted an

New Polymer Films Conduct Heat Instead of Trapping It

Polymers are usually the go-to material for thermal insulation. Think of a silicone oven mitt, or a Styrofoam coffee cup, both manufactured from polymer materials that are excellent at trapping heat. Now MIT engineers have flipped the picture of the standard polymer

Researchers Find Ways to Image, Characterize Unique New Material

Graphene can come from graphite, but borophene? There’s no such thing as borite. Unlike its carbon cousin, two-dimensional borophene can’t be reduced from a larger natural form. Bulk boron is usually only found in combination with other elements, and is certainly not layered,

Design and Validation of Multilayered Thermal Emitter Using Machine Learning

Scientists designed a multilayered metamaterial that realizes ultra-narrowband wavelength-selective thermal emission by combining the machine learning (Bayesian optimization) and thermal emission properties calculations (electromagnetic calculation). The joint team then experimentally fabricated the designed metamaterial and verified the performance. These results may facilitate
