 NanoThermoMechanical AND and OR Logic Gates
- Based on the coupling between near-field thermal radiation and MEMS thermal actuation, we presented the design and modeling of NanoThermoMechanical AND, OR, and NOT logic gates as an alternative, and showed their ability to be combined into a full thermal adder to perform complex operations. In this work, we introduce the fabrication and ...

 Early deformation mechanisms in the shear affected region underneath a copper sliding contact
- By depositing two layers of platinum (SEM followed by FIB), the surface of the copper sample was protected from ion beam damage during FIB micromachining. The TEM foil was cut in the middle of the wear track, perpendicular to the sliding surface and parallel to the sliding direction. TEM foil preparation followed the procedure described by ...

 New air-pressure sensor could improve everyday devices
- After finding a new type of MEMS (microelectromechanical system) that allows better control, the researchers have used that knowledge to build an air-pressure sensor that could improve many everyday devices. "This is the same mechanism as devices we've designed in the past, but it's a different application," said principal investigator Shahrzad ...

 PW2020: DARPA seeking close cooperation with photonics sector
- Some devices cited by John Burke, of DARPA’s Microsystems Technology Office, would help PC-toting warfighters of the future, like technology from AMBIIENT (Atomic Magnetometer for Biological Imaging in Earth’s Native Terrain). As an example, Burke cited the intrinsic magnetic gradiometer. He was a keynote speaker at Photonics West’s ...

 New Technion micromachine to introduce DNA, drugs into specific cells
- Currently, this technique can only be applied to numerous cells at once, rather than targeting a single specific cell. However, Yossifon's micromachine is able to do exactly that. Micromachines, also known as "active particles" and "micro-motors," are becoming more viable as a micro and nanoscale tool for single-cell analysis. These machines ...

 Nano 2020: Scaling up nanotechnology in virtual reality
- Sometimes the smallest of things lead to the biggest ideas. Case in point: Nano 2020, a University of Arizona-led initiative to develop curriculum and technology focused on educating students in the rapidly expanding field of nanotechnology. The five-year, multi-university project recently met its goal of creating globally relevant and ...

 A novel formulation to explain heat propagation
- This can explain why and under which conditions heat propagation becomes fluid-like rather than diffusive. Their equations will make it easier to design next-generation electronic devices at the nanoscale, in which these phenomena can become prevalent. Fourier's well-known heat equation describes how temperatures change over space and time when ...

 Discovery brings nanoscale thermal switches needed for next-gen computing
- The journal Nature Nanotechnology published an Army-funded study from University of Michigan researchers that showed for the first time how a nanoscale thermal switch can be built by employing nanoscale effects that arise when heat is transferred between a hot and cold nanoscale-thick membrane via thermal radiation. In comparison to the vast ...
