The cement industry emits more than 3 gigatons of carbon dioxide worldwide from the manufacturing of about 4.5 gigatons of cement every year because of its carbon-dioxide- and energy-intensive processing. This amount of cement is necessary to produce the concrete that shapes modern infrastructure.
Researchers have produced new evidence of how graphene, when twisted to a precise angle, can become a superconductor, moving electricity with no loss of energy. In a study published today (Feb. 15, 2023) in the journal Nature, the team led by physicists at The Ohio State University reported on the key role that quantum geometry plays in allowing this twisted graphene to become a superconductor.
Today, 20/15 Visioneers, a leading strategy, technology, and marketing consultancy, announced their second annual low-carbon footprint Materials Science Mega Webinar and a call for speakers.
Society’s growing demand for high-voltage electrical technologies—including pulsed power systems, cars and electrified aircraft, and renewable energy applications—requires a new generation of capacitors that store and deliver large amounts of energy under intense thermal and electrical conditions. Researchers at Lawrence Berkeley National Laboratory and Scripps Research have now developed a new polymer-based device that efficiently handles record amounts of energy while withstanding extreme temperatures and electric fields.
A team of FAMU-FSU College of Engineering researchers at the High-Performance Materials Institute completed the first-ever study on how purified boron nitride nanotubes remain stable in extreme temperatures in inert environments.
Georgia Tech-Europe and MIT researchers are using emerging technology to demonstrate a process that will enable more immersive and realistic virtual and augmented reality displays with the world’s smallest and thinnest micro-LEDs.
A new type of solar technology has seemed promising in recent years. Halide perovskite solar cells are both high performing and low cost for producing electrical energy – two necessary ingredients for any successful solar technology of the future. But new solar cell materials should also match the stability of silicon-based solar cells, which boast more than 25 years of reliability.
Thinking beyond COVID-19, a team led by Srikanth Singamaneni at the McKelvey School of Engineering developed a new point-of-care diagnostic test that is 1,000 times more sensitive than conventional rapid tests and can quantify concentrations of proteins.
Lithium-ion batteries have remained unrivaled in terms of overall performance for several applications, as evidenced by their widespread use in everything from portable electronics to cellular base stations.
Arizona State University has officially begun a new chapter in X-ray science with a newly commissioned, first-of-its-kind instrument that will help scientists see deeper into matter and living things. The device, called the compact X-ray light source (CXLS), marked a major milestone in its operations as ASU scientists generated its first X-rays on the night of Feb. 2.
Devices currently in development that clean up dirty water using sunlight can only produce a few gallons of water each day. But now, researchers in ACS Central Science report how a sunlight-powered porous hydrogel could potentially purify enough water to meet daily needs — even when it’s cloudy.
The Korea Institute of Science and Technology (KIST, President Seok Jin Yoon) announced that Dr. Jihyun Hong's research team at the Energy Materials Research Center identified the cause of the rapid decline in life span-a chronic problem of high-capacity manganese-based spinel cathode materials.
Excitons are drawing attention as possible quantum bits (qubits) in tomorrow’s quantum computers and are central to optoelectronics and energy-harvesting processes. However, these charge-neutral quasiparticles, which exist in semiconductors and other materials, are notoriously difficult to confine and manipulate. Now, for the first time, Berkeley Lab researchers have created and directly observed highly localized excitons confined in simple stacks of atomically thin materials. The work confirms theoretical predictions and opens new avenues for controlling excitons with custom-built materials.
A new sodium battery technology shows promise for helping integrate renewable energy into the electric grid. The battery uses Earth-abundant raw materials such as aluminum and sodium.
Slips, trips and falls (STFs) remain the top causes of major injuries in the workplace. Harnessing the power of research and technology to boost workplace safety, Professor Lim Chwee Teck from the National University of Singapore’s (NUS) Department of Biomedical Engineering, which is under the College of Design and Engineering, as well as Institute for Health Innovation & Technology (iHealthtech), collaborated with NUS start-up, FlexoSense, to develop a smart insole which can track workplace STFs in real time and is the first of its kind that can detect a person’s balance.
Until now, it has been clear: you can have a metal or a plastic, but not both in one. However, things don’t have to stay that way. In the journal Angewandte Chemie, a Chinese research team has now reported a polymer with a metallic backbone that is conductive, thermally stable, and has interesting optoelectronic properties.
Scientists at the University of Portsmouth are to develop ‘plastic-eating’ enzymes that could help solve the ever-growing problem of waste polyester clothing.
Korea Research Institute of Standards and Science (KRISS, President Hyun-Min Park) developed a non-contact flow sensor capable of measuring the amount of epoxy used in the semiconductor fabrication process in real time.
Scientists have found the secret behind a property of solid materials known as ferroelectrics, showing that quasiparticles moving in wave-like patterns among vibrating atoms carry enough heat to turn the material into a thermal switch when an electrical field is applied externally.
The researchers from Lithuania and Cyprus claim that the energy payback period of using phase change materials, new technology in the construction industry, is the shortest in a colder climate.
