Annealing

By Daren E. Daugaard, PhD, PE, Lee Enterprise Consulting Special to The Digest Since its inception over 4,000 years ago, steel has been the foundation of global modernization in building construction, transportation, and manufacturing.  Steel and iron production ranks first in total global CO2 emissions at 8% and second in overall energy consumption.  The industry […]

Femtosecond (fs) laser direct writing (FLDW) is a laser micro/nano manufacturing technology that can focus the laser pulses on the surface or inside the material, causing local changes in material properties through nonlinear laser-material interactions, which has been widely used in many fields such as micro/nano photonics, integrated optics, microfluidics. Conventional FLDW has the problem of asymmetric lateral…

A new thermoelectric device developed by scientists at Penn State University shows great potential for future success in providing cooling solutions for next-generation electronics.

EPFL engineers have built and tested a solar reactor that generates hydrogen gas from sunlight and water. The system is not only highly efficient at producing hydrogen, it also captures the "waste" products of oxygen and heat to put them to use too.

A research team, led by the Nano Optics Group within the Department of Physics at UNIST has reported achieving all-vanadium dioxide (VO2) multifunctional metasurfaces, which perform as a transparent window in the broadband THz regime with variable DC conductivity of dynamic range over three decades and selective switchability of near-infrared (NIR) diffraction.

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have developed a new way to guide the self-assembly of a wide range of novel nanoscale structures using simple polymers as starting materials. Under the electron microscope, these nanometer-scale structures look like tiny Lego building blocks, including parapets for miniature medieval castles and Roman aqueducts. But rather than…

Some solid materials have a memory of how they have previously been stretched out, which impacts how they respond to these kinds of deformations in the future. A new Penn State study lends insight into memory formation in the foams and emulsions common in food products and pharmaceuticals and provides a new method to erase this memory, which could guide how materials are prepared for future use.

Sheet metal is extremely handy for all kinds of jobs since it's so easy to work with. You can do a lot with only a…

LOS ALAMOS, N.M., Aug. 15, 2022 — Recent research proves that under certain conditions, quantum annealing computers can run algorithms—including the well-known Shor's algorithm—more quickly than classical computers. In most cases, however, quantum annealing does not provide a speed-up compared to classical computing when time is limited, according to a study in Nature Communications.   "We […]

Over-the-counter pain relievers, physical therapy, steroid injections—some people have tried it all and are still dealing with knee pain.

Using single calcite crystals with varying surface roughness allows engineers to simplify the complex physics that describes fault movement. In a new study from the University of Illinois Urbana-Champaign, researchers show how this simplification may lead to better earthquake prediction.
