Using an alcohol mixture, researchers modified how ink droplets dry, enabling cheap industrial-scale printing of electronic devices at unprecedented scales.
UC Riverside engineering professors Mihri and Cengiz Ozkan and their students have been working for years on creating improved energy storage materials from sustainable sources, such as glass bottles, beach sand, Silly Putty, and portabella mushrooms. Now they have turned plastic soda bottles into a nanomaterial for use in batteries. Though they don't store as much energy as lithium-ion batteries, supercapacitors made with the material can charge much faster.
Materials scientists studying recharging fundamentals made an astonishing discovery that could open the door to better batteries, faster catalysts and other materials science leaps.
A multi-institution research team led by Andre ? D. Taylor, professor of chemical and biomolecular engineering at the NYU Tandon School of Engineering demonstrated a novel approach to MXene fabrication that could lead to methods for at-scale production of MXene freestanding films: drop-casting onto prepatterned hydrophobic substrates. Their method led to a 38% enhancement of EMI shielding efficiency over conventional methods.
Researchers have found electrons that behave as if they have no mass, called Dirac electrons, in a compound used in rewritable discs, such as CDs and DVDs. The discovery of "massless" electrons in this phase-change material could lead to faster electronic devices.
POSTECH professor In Su Lee's research team develops a magnetic field-induced heating 'hollow nanoreactors'.
In research published in Science Advances, a group led by scientists from the RIKEN Center for Emergent Matter Science (CEMS) have used a principle, "magneto-rotation coupling," to suppress the transmission of sound waves on the surface of a film in one direction while allowing them to travel in the other.
ORNL Story Tips: Pandemic impact, root studies, neutrons confirm, lab on a crystal and modeling fusion.
A small device, called "Smart Stirrer", performed a function of a conventional laboratory stir bar, has an integrated microprocessor and various sensors capable of wireless and autonomous report the conversion of properties of a solution. Results are sent to a computer over Bluetooth, and any changes notify the user wirelessly.
A material composed of two one-atom-thick layers of carbon has grabbed the attention of physicists worldwide for its intriguing -- and potentially exploitable -- conductive properties. University of Texas at Dallas physicists are studying how the ability of twisted bilayer graphene to conduct electrical current changes in response to mid-infrared light.
