Recently, researchers at the University of Glasgow in Scotland have discovered how to produce large sheets of high-quality graphene in a way that is 100 times less expensive than previous methods. “The University of Glasgow team decided to see if they could make graphene with copper foils, which are already being cheaply made in bulk to create common household lithium-ion … [Read more...]
New Platform for Nanoscale Thermal Measurements
A CCNY team led by physics professors Carlos Meriles and Elisa Riedo recently reported on a platform for nanoscale thermal measurements based on magnetic resonance, and optical and atomic force microscopy. “Their paper, ‘Imaging thermal conductivity with nanoscale resolution using a scanning spin probe,’ is based on a simple notion: that a hot probe in contact with a thermally … [Read more...]
A Figure of Merit for Smart Phone Thermal Management
By Victor Chiriac1, Steve Molloy1, Jon Anderson1, Ken Goodson2 1 Qualcomm Technologies, Inc., 2 Stanford Mechanical Engineering Introduction With smart phones and other mobile devices available in a variety of sizes and shapes, it is challenging to think in a consistent and comparative manner about the effectiveness of the thermal management solutions that they employ. This … [Read more...]
Extreme-Temperature Probing Solutions Offered
Keysight Technologies recently introduced the N7007A extreme-temperature 400-MHz passive probe and the N7013A extreme-temperature extension kit for medium- and high-voltage differential active probes. According to the company, the extreme-temperature probing solutions offer bandwidths up to 400 MHz, and can withstand temperatures ranging from -40 degrees to +85 degrees … [Read more...]
New Synthetic ‘Water Adhesive’ Stronger than Natural Adhesives
MIT engineers have developed a synthetic, sticky hydrogel – or “tough, bonding water,” as lead paper author Hyunwoo Yuk calls it – that could be used as an adhesive for boats, submarines and other underwater surfaces. Hydrogel is tough, transparent, adheres to glass, silicon, aluminum, ceramics and titanium, and is made up mostly of water. According to Phys.org, to create the … [Read more...]
