Metal encapsulation optimizes chemical reactions

The chemical industry consumes millions of tons of packing materials as catalytic sup- port media or adsorbents in fixed-bed reactors and heat storage systems. Fraunhofer researchers have developed a means of encapsulating ...

Can heat be controlled as waves?

A growing interest in thermoelectric materials—which convert waste heat to electricity—and pressure to improve heat transfer from increasingly powerful microelectronic devices have led to improved theoretical and experimental ...

Ultrafast heat conduction can manipulate nanoscale magnets

Researchers at the University of Illinois at Urbana-Champaign have uncovered physical mechanisms allowing the manipulation of magnetic information with heat. These new phenomena rely on the transport of thermal energy, in ...

Squeezing out new science from material interfaces

With more than five times the thermal conductivity of copper, diamond is the ultimate heat spreader. But the slow rate of heat flow into diamond from other materials limits its use in practice. In particular, the physical ...

Graphene meets heat waves

EPFL researchers have shed new light on the fundamental mechanisms of heat dissipation in graphene and other two-dimensional materials. They have shown that heat can propagate as a wave over very long distances. This is key ...

Researchers discover new material to produce clean energy

Researchers at the University of Houston have created a new thermoelectric material, intended to generate electric power from waste heat - from a vehicle tailpipe, for example, or an industrial smokestack - with greater efficiency ...

What is heat conduction?

Heat is an interesting form of energy. Not only does it sustain life, make us comfortable and help us prepare our food, but understanding its properties is key to many fields of scientific research. For example, knowing how ...

Does dark magma lurk in deep Earth?

(Phys.org) —A key to understanding Earth's evolution is to look deep into the lower mantle—a region some 400 to 1,800 miles (660 to 2,900 kilometers) below the surface, just above the core. Data have suggested that deep, ...
