University of Rochester researchers adapt excited state lifetime thermometry to extract temperatures of nanoscale materials from light emitted by nitrogen vacancy centers in individual nanodiamonds. The approach is less complicated, more accurate, and safer for sensitive materials or biological tissues than optically detected magnetic resonance.
Researchers from KTH Royal Institute of Technology and Stanford University fabricated electrochemical random access memory components from 2D titanium carbide (MXenes) that showed outstanding potential for complementing classical transistor technology.
Researchers at CNR Nano in Pisa, TU Wien, and the University of Antwerp developed an electrochemical etching process that turns solid silicon carbide into porous graphene nanostructures. About 42% of the volume is removed in the process.
A newly created nano-architected material exhibits a property that previously was just theoretically possible: it can refract light backward, regardless of the angle at which the light strikes the material.
Graphene-Based Nanomaterial Catalysis describes methods of fabrication of both functionalized and nonfunctionalized graphene nanomaterials suitable for use in a variety of applications, including electrochemical sensors, oxygen and hydrogen production, fuel cells, and organic transformations.
Transmutex is developing a new type of nuclear reactor that burns thorium instead of uranium. In theory, these power plants would be able to produce electricity safely and without highly radioactive waste.
Scientists from Korea Maritime and Ocean University developed a novel co-doped carbon material for the anode of a type of sodium-based battery called seawater batteries.
A collaborative team of scientists at École polytechnique fédérale de Lausanne demonstrated a technique for producing perovskite photovoltaic materials on an industrial scale. They designed a co-solvent dilution strategy that can be used with spin coating.
Researchers from Waseda University and CSIR-Central Electrochemical Research Institute demonstrated a technique called “sampled current voltammetry” as a more reliable indicator of electrocatalytic performance at a constant steady-state applied voltage.
Researchers compared the effects of ash derived from both sunflower stalks and corn cobs on the compressive strength of concrete. They concluded that both materials reduced the tensile and compressive strength of concrete but improved resistance to hydrochloric acid and freeze-thaw cycles.
Researchers at Rice University and the Kuwait Institute for Scientific Research found that common Portland cement contains microscopic crystals of silicon, which emit near-infrared fluorescence when illuminated with visible light. The near-infrared emission can reveal tiny microcracks that are invisible to the naked eye.
Superconductors have four classic traits, including conducting electric current without loss and levitating magnets. Now the discovery of the fourth and final trait—the way electrons pair up and condense into a sort of electron soup—by SLAC National Accelerator Laboratory and Stanford University researchers caps 15 years of detective work.
Researchers from the Kavli Institute for the Physics and Mathematics of the Universe and the University of Minnesota developed an alumina short-wavelength absorber patterned with moth eye-like structures. These new anti-reflective structures will improve the performance of telescopes studying radiation from the Big Bang.
A Sandia National Laboratories supercomputer simulation model called SNAP has captured the melting of diamond when compressed by extreme pressures and temperatures. The work could have important implications for nuclear fusion efforts that employ capsules made of polycrystalline diamond.
The NSF Engineering Research Visioning Alliance is seeking volunteers for leadership positions on their advisory board and standing council. Deadline to apply is February 13.
Armin VahidMohammadi and Babak Anasori are hosting a 45-min webinar on the art of scientific illustrations and data visualization. The webinar takes place February 18 from 3–3:45 p.m. Eastern at the AAAS 2022 Annual Meeting. Basic registration is free.
The second Workshop for Young Researchers in Ceramics and Glasses for Medical Applications (Y-CGMEd) will be organized by SECV on May 5–6, 2022, at the Institute for Ceramics and Glasses in Madrid, Spain.
