The electric vehicle market's biggest hurdles today are improving and cost reducing battery technology. A new fabrication technique at Georgia Tech could allow solid-state automotive lithium-ion batteries to adopt nonflammable ceramic electrolytes using the same production processes as in batteries made with conventional liquid electrolytes. These conventional Li-ion manufacturing tools are driving better fabrication options to enable battery makers to produce lighter, safer, and more energy-dense batteries.
Munich is home to the world's first fully automated sensor network for measuring urban greenhouse gas emissions based on ground-based remote sensing of the atmosphere. It has been developed by scientists in the group of Jia Chen, Professor of Environmental Sensing and Modeling at the Technical University of Munich (TUM). Now, anyone can view the measurement data via an Internet platform.
It's no secret that the United States' $13 billion cannabis industry is big business. Less obvious to many is the environmental toll this booming business is taking, in the form of greenhouse gas emissions from commercial, mostly indoor production. A new study by Colorado State University researchers provides the most detailed accounting to date of the industry's carbon footprint, a sum around which there is only limited understanding.
The process retains properties of fibres at a higher rate than previous methods, demonstrating a retention strength of up to 90 percent. Recycling of composite materials could be up to 70 percent cheaper and lead to a 90-95 percent reduction in CO2 emissions compared to standard manufacturing.
Tokyo, Japan - Researchers from Tokyo Metropolitan University have studied the properties of mixtures of silicone-coated "magic sand", a popular kid's toy, and normal sand. Silicone-coated sand particles were found to interact with each other only, and not with other sand particles. The team discovered that adding silicone-coated sand beyond a certain threshold leads to an abrupt change in clustering and rigidity, a simple, useful way to potentially tune the flow of granular materials for industry.
University of Tsukuba and Institute of High Pressure Physics scientists mapped the spin-density distribution of electrons travelling through a molybdenum disulfide transistor cooled to almost absolute zero. This work may help advance the field of spin-based electronics that would be faster and more efficient compared with current devices.
Professor Byoungwoo Kang develops a high-density cathode material through controlling local structures of the Li-rich layered materials.
Texas A&M University researchers have recently shown superior performance of a new oxide dispersion strengthened (ODS) alloy they developed for use in both fission and fusion reactors.
Using thin films -- no more than a few pieces of notebook paper thick -- of a common explosive chemical, researchers from Sandia National Laboratories studied how small-scale explosions start and grow.
Metal organic framework helps silver catalyst to turn greenhouse gas into useful chemical feedstock.
