Researchers developed a graphene nanoflake-based film for efficient cooling of electronics, achieving over 76% improvement in heat transfer efficiency. The functionalization layer constrains cross-plane scattering of low-frequency phonons, enhancing in-plane heat conduction and reducing contact resistance.
Scientists at Jülich and Aachen have developed a method to control the conducting properties of topological insulators more precisely. By stacking materials instead of mixing, they optimized conductivity and reduced energy requirements. This breakthrough could lead to faster and more efficient computers and mobile phones.
Researchers from the University of Illinois found that standard thermal models fail for nanoscale heat-transfer problems when dimensions are on the order of one micron or smaller. Heat is transported ballistically, not diffusively, and interfaces add significant thermal resistance.
Scientists used a probe to study boron atoms in glass under pressures up to 2.5 Gigapascal, revealing the transition from flat triangular configuration to a four-sided tetrahedron shape.
A team from the University of the Basque Country has repeated an experiment that previously found spider silk to be an excellent thermal conductor. Their results show a significant decrease in thermal diffusivity, with values up to 300 times smaller than those reported earlier.
Researchers at Berkeley Lab developed a process-friendly technique to cool microprocessor chips using carbon nanotubes, improving heat transport efficiency by six-fold. The method, suitable for manufacturing computer chips, reduces thermal interface resistance and enhances cooling performance.
A University of Colorado Cancer Center review found that resistant starch kills pre-cancerous cells and reduces inflammation, promoting the growth of good bugs in the bowel. Consuming resistant starch, found in legumes, green bananas, and starchy products, may also have implications for breast cancer prevention.
Many fruit fly species lack heat resistance, making them vulnerable to predicted global temperature increases. Researchers found that most tropical and mid-latitude species are at risk of extinction without adaptation.
A researcher at the University of Arizona is working on high-temperature resistant ceramic coatings to protect Air Force hypersonic aircraft. The coating can withstand temperatures up to 2800 degrees Celsius and has the potential to enable faster travel times.
The US Consumer Product Safety Commission (CPSC) has adopted a new federal standard for mattresses, setting a maximum heat release rate to reduce the risk of flashover. The standard is expected to save an estimated 270 lives and prevent 1,330 injuries annually.
Scientists at NIST have developed prototype pyroelectric detectors coated with carbon nanotubes, showing improved heat conduction and laser resistance. The coating absorbs light and converts it to heat, generating a current that measures the power of the laser.
Researchers found that carbon nanotubes exhibit lower thermal conductivity when integrated into other materials due to interfacial resistance. Despite this, they remain optimistic about using nanotubes to improve insulating materials.
Researchers at INEEL have developed a revolutionary Super Hard Steel coating with unparalleled hardness properties, surpassing existing commercial coatings in wear and corrosion resistance. The coating can withstand extreme conditions, including high velocity blasting, and is nearly impossible to remove.
