A team of University of Maryland scientists have discovered that when electric current is run through carbon nanotubes, objects nearby heat up while the nanotubes themselves stay cool. Understanding this completely unexpected new phenomenon could lead to new ways of building computer processors that can run at higher speeds without overheating. The researchers have dubbed the … [Read more...]

Magnetic Testing Ensures Reliability of Microelectronic Devices
Researchers at the Georgia Institute of Technology have developed a new technique for measuring the adhesion strength between thin films of materials used in microelectronic devices, photovoltaic cells and MEMS using magnetic repulsion. The fixtureless and noncontact technique, known as the magnetically actuated peel test (MAPT), could help ensure the long-term reliability of … [Read more...]
New R&D Performance Record with 254 Lumen-Per-Watt Power LED

Researcher Finds Cheaper Way To Cool Electronic Devices
A North Carolina State University researcher has developed a technique that uses a “heat spreader” made of a copper-graphene composite, which is attached to the electronic device using an indium-graphene interface film, both of which have higher thermal conductivity, allowing the device to cool efficiently. Dr. Jag Kasichainula, an associate professor of materials science and … [Read more...]
