The amount of surface oxygen in graphene materials is a key factor in how effective they could be in killing bacteria – a discovery which may help to design safer and more effective products to combat antimicrobial resistance.
Researchers at Universidad Carlos III de Madrid (UC3M) have created software and hardware for a 4D printer with applications in the biomedical field. In addition to 3D printing, this machine allows for controlling extra functions: programming the material’s response so that shape-changing occurs under external magnetic field, or changes in its electric properties develops under mechanical deformation.
Researchers have developed a new "camera" that sees the local disorder in materials. Its key feature is a variable shutter speed: because the disordered atomic clusters are moving, when the team used a slow shutter, the dynamic disorder blurred out, but when they used a fast shutter, they could see it. The method uses neutrons to measure atomic positions with a shutter speed of around one picosecond, a trillion times faster than normal camera shutters.
As the evolution of standard microchips is coming to an end, scientists are looking for a revolution. The big challenges are to design chips that are more energy efficient and to design devices that combine memory and logic (memristors).
Scientists at Berkeley Lab have developed a polymer coating that could enable longer lasting, more powerful lithium-ion batteries for electric vehicles. The advance opens up a new approach to developing EV batteries that are more affordable and yet easy to manufacture.
Scientists develop method for chemically modifying nanoscale tubes of carbon atoms, so they can host spinning electrons to serve as stable quantum bits in quantum technologies.
Electrons in magnetic solids feel each other as an effective magnetic field that forces the electrons’ spins to align. If the arrangement of atoms is not fully symmetric, an additional magnetic force known as Dzyaloshinskii-Moriya Interaction (DMI) can emerge, forcing the spins to reorient and form whirling patterns called skyrmions. Researchers joined two different materials to enable skyrmion generation.
Researchers from Tokyo Metropolitan University have successfully threaded atoms of indium metal in between individual fibers in bundles of transition metal chalcogenide nanofibers.
With the push for renewable energy, researchers from Clemson University and the Indian Institute of Science have designed a smart supercapacitor using a novel stack of metal oxides — vanadium pentoxide and zinc oxide — that can efficiently harvest energy from sunlight and simultaneously store it.
The Korea Institute of Science and Technology (KIST, President Seok Jin Yoon) has announced that Dr. Ji-Soo Jang's team from the Electronic Materials Research Center and Prof. Tae-Gwang Yoon's team from the Department of Materials Science and Engineering, Myongji University (President Byeong-Jin Yoo) have jointly developed an advanced membrane that can simultaneously provide drinking water and generate continuous electricity from various water resources, such as sewage/wastewater, seawater, and groundwater.
Dr. Sang Kyung Kim (Director) and Dr. Seungwon Jung’s research team at the Center for Augmented Safety System with Intelligence, Sensing of the Korea Institute of Science and Technology (KIST, President: Seok Jin Yoon) announced that they had developed an ultrafast PCR technology.
A research team led by Dr. Yong-hun Kim and Dr. Jeong-Dae Kwon has successfully developed the world’s first neuromorphic semiconductor device with high-density and high-reliability by developing a thin film of lithium-ion battery materials.
Electronics and Telecommunications Research Institute(ETRI) announced that it has developed a fluorosulfate-based flame retardant additive with significantly improved flame retardant properties, electrochemical stability, and cell performance compared to triphenyl phosphate(TPP), a phosphorous flame retardant widely known as a conventional flame retardant (not yet commercialized).
A research team led by Dr. Bon-Cheol Ku of the Korea Institute of Science and Technology (KIST, President Seok Jin Yoon) Jeonbuk Institute of Advanced Composite Materials collaborated with a research team led by Professor Han Gi Chae from the Ulsan National Institute of Science and Technology (UNIST, President Yong Hoon Lee) to develop a low-cost fabrication technology for carbon-nanotube-based composite carbon fibers with extremely high tensile strength and high modulus.
Scientists at the University of Sussex have successfully trialed new biodegradable health sensors that could change the way we experience personal healthcare and fitness monitoring technology.
A study by an international and interdisciplinary team headed by Freiburg archaeologist Dr. Ralph Araque Gonzalez from the Faculty of Humanities has proven that steel tools were already in use in Europe around 2900 years ago.
A liquid nitrogen spray developed by Washington State University researchers can remove almost all of the simulated moon dust from a space suit, potentially solving what is a significant challenge for future moon-landing astronauts.
A new form of heterostructure of layered two-dimensional (2D) materials may enable quantum computing to overcome key barriers to its widespread application, according to an international team of researchers.
Argonne researchers have developed an artificial intelligence-based model to greatly speed up the process for engineering a low-cost catalyst that converts biomass into fuels and useful chemicals with many possible applications.
