Metal feels colder than wood because it rapidly transfers heat away from your body due to its dense atomic structure and free electrons. This efficient heat conduction triggers a stronger sensation of ...

Metals are known as good conductors of both heat and electricity. Regardless of temperature or other factors, typical conductivity does not change. This property is known as the Wiedemann-Franz Law.

Toray has developed a high thermal conductivity technology that lifts the heat-dissipating properties of carbon fiber-reinforced plastic (CFRP) to that of metals. Applying this technology to CFRP ...

A method for the accurate measurement of thermal conductivity in the temperature region below 1°K has been developed. This method has been used to determine the heat conductivity of very pure samples ...

Cellulose is by far the most common biopolymer on the planet, and it is well known for its renewable, biocompatible, and biodegradable nature. Cellulose is a type of linear polysaccharide (β (1−4) ...

In recent years, the use of Phase Change Materials (PCMs) in thermal management systems (TMS) has garnered increased interest due to their high latent heat storage capacity, which enables effective ...

Engineers have flipped the picture of the standard polymer insulator, by fabricating thin polymer films that conduct heat -- an ability normally associated with metals. In experiments, they found the ...

Cool Polymers Warwick, R.I. It's no secret that designers don't hesitate putting plastics in products that serve almost every industry and market sector. But as the demand for smaller, ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Polymers are generally put to work as insulators, but a team of ...

To their surprise, they found that the thermal conductivity attributed to the electrons is ten times smaller than what would be expected from the Wiedemann-Franz Law. "The electrons were moving in ...
