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...]
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...]
Viable Energy Storing Solution Combines Metal Nitrides and Graphene
A*STAR researchers have developed a viable energy storing solution for supercapacitors by combining metal nitride electrodes with thin sheets of graphene. According to Phys.org, Hui Huang from A*STAR's Singapore Institute of Manufacturing Technology and his colleagues from Nanyang Technological University and Jinan University, China, call it an “asymmetric” supercapacitor, … [Read more...]
Researchers Use Infrared Laser to Refrigerate Liquids
Recently, the University of Washington research team has successfully used an infrared laser to cool water. According to Phys.org, the process uses a microscopic crystal suspended in water and an infrared laser light, to cool the water to about 36 degrees Fahrenheit. The heat from the infrared laser excites a kind of glow from the crystal that has “slightly more energy than … [Read more...]
Graphene Can Now Be Applied to Thermal Imaging Devices
Researchers from MIT have built a chip out of graphene that could be applied to thermal imaging devices. “Graphene is one of the best-known infrared sensing materials, so the team built a microscopic sensor chip out of the material,” Engadget reported. “Further graphene was then used to carry the signals and suspend the chip over an air pocket. That eliminated the need for … [Read more...]
