A new analysis looks at what it would take for oil companies to start pumping millions of tons of carbon dioxide into their wells to boost crude production -- and what it would mean for the climate.
Variations in power generation using renewable sources lead to control problems in the electricity grid. The technology of lithium batteries is a candidate offering great potential in solving these problems. An industrial engineer at the Public University of Navarre (NUP/UPNA) has developed a new management system that allows good performance of these batteries to be achieved and their lifetime to be preserved when connected to a renewable facility to store the electrical energy produced.
Study explains how radioactive radium transfers to wastewater in the widely-used method to extract oil and gas.
A new discovery of a light-induced super photobase at Michigan State University is revealing some of photosynthesis' desirable traits. The interdisciplinary team of scientists was able to document the ultrafast dynamics of the super photobase that is 10 million times stronger than anything previously discovered.
Scientists at the University of Tokyo have recorded the largest magnetic field ever generated indoors -- a whopping 1,200 tesla, as measured in the standard units of magnetic field strength. The high magnetic field also has implications for nuclear fusion reactors, a tantalizing if unrealized potential future source of abundant clean energy. The experiments that set the new world record are described in this week's Review of Scientific Instruments.
Researchers have developed a new mechanism to protect enzymes from oxygen as biocatalysts in fuel cells. The enzymes, known as hydrogenases, are just as efficient as precious metal catalysts, but unstable when they come into contact with oxygen. They are therefore not yet suitable for technological applications. The new protective mechanism is based on oxygen-consuming enzymes that draw their energy from sugar.
A novel technology could provide a solution for cooling processes: refrigeration using magnetic materials in magnetic fields. Researchers at the Technische Universität (TU) Darmstadt and the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have developed the idea of a cooling cycle based on the 'magnetic memory' of special alloys. Relevant initial experimental results have been published in the journal Nature Materials.
A team of researchers affiliated with South Korea's Ulsan National Institute of Science and Technology has introduced a novel technology that promises to significantly boost the performance of lithium metal batteries.
EPFL chemists have developed a method that can significantly increase the yield of sugars from plants, improving the production of renewable fuels, chemicals, and materials.
The University of Tokyo Institute of Industrial Science researchers have created a model to explore the transition behavior of crystal lattices. Their system, based on spheroid particles with a permanent dipole, showed that the combination of anisotropic steric and dipole effects causes frustration that induces the coupling between polarization and strain, resulting in the self-organization. These findings are expected to contribute to the rational design of materials for applications including electro-mechanical actuators and electro-caloric refrigerators.
