Researchers from the Technical University of Hamburg and the Massachusetts Institute of Technology, in collaboration with the Helmholtz-Zentrum Geesthacht and Bremen University, achieved the assembly of iron oxide nanoparticles into strong macrostructures via 3D printing.
Researchers led by University of Oviedo in Spain discovered an effective method based on intercalation for controlling the frequency of confined light at the nanoscale in the form of phonon polaritons.
Researchers at the University of Texas at Dallas and Hanyang University found fibers created with carbon-based nanotubes create supercapacitors when coated with, or submerged in, an electrolyte such as salt water.
Scientists at Japan’s Institute for Integrated Cell-Material Sciences found a new coordination polymer glass membrane works just as well as its liquid counterparts, with added strength and flexibility, in fuel cells.
Researchers at The Hong Kong Polytechnic University developed a laser manufacturing process that deposits a few layers of graphene onto commercially-available nonwoven masks. The coating makes the masks superhydrophobic while graphene’s strong light-absorption properties makes it possible to sterilize them with exposure to sunlight.
Engineers at the National Institute of Standards and Technology produced a list of high priority research needs for the design, maintenance, and operation of plumbing systems, including questions on how water flow and plumbing design affect water quality and what factors influence chemical reactions and bacterial growth in pipes.
Researchers from National Central University in Taiwan developed a UV and heat resistant, self-healing emulsion glass. The impressive arsenal of properties makes the liquid-like solid material perfect for a supporting medium, whereby UV and heat-curable inks can be “3D written” directly into it and cured independently of the surrounding liquid-like solid.
Researchers in China modified the deflection formula for prestressed concrete hollow slab (closed section beam) based on the Timoshenko theory, a classical theory often used to calculate the deformation of beams.
Researchers at Texas A&M University and the company Essentium, Inc. integrated plasma science and carbon nanotube technology into standard 3D printing, allowing them to weld adjacent printed layers more effectively and increase the overall reliability of the final part.
Researchers reported a new resin that expands upon heating, which could allow for 3D-printed objects to be bigger than the machines that make them.
U.S. Naval Research Laboratory researchers developed a new gallium nitride-based electrical component called a resonant tunneling diode with performance beyond the anticipated speed of 5G. They developed a repeatable process to increase the diodes yield to approximately 90%; previous typical yields range around 20%.
Researchers carried out a prediction of stable molybdenum borides and their crystal structures and found the highest borides contain four to five boron atoms per each molybdenum atom. The estimated Vickers hardness of MoB5 is 37–39 GPa, which makes it a potential superhard material.
Researchers from the Jülich Aachen Research Alliance and the German technology group Heraeus described how the switching and neuromorphic behavior of memristive elements can be selectively controlled. According to their findings, the crucial factor is the purity of the switching oxide layer.
Researchers at the Skolkovo Institute of Science and Technology and the Moscow Institute of Physics and Technology figured out a link between an element’s position in the Periodic Table and its potential to form a high-temperature superconducting hydride.
Researchers at SLAC National Accelerator Laboratory showed a pulse of laser light can dramatically change the spin state of a manganese oxide-based quantum material known as NSMO while leaving its orbital state intact.
Hollow-core fiber technology developed in the Optoelectronics Research Centre at the Zepler Institute for Photonics and Nanoelectronics exhibits up to 1,000 times better polarisation purity than state-of-the-art solid core fibers.
