Researchers of Peter the Great St. Petersburg Polytechnic University (SPbPU) developed a new approach to determine the best electrode materials composition for Solid-state lithium-ion batteries. The research group of St. Petersburg Polytechnic University developed a method to determine the electrochemical capacity of each component of the "nickel-cobalt oxide" system.
In the near future dyes in electric motors might indicate when cable insulation is becoming brittle and the motor needs replacing. Scientists at Martin Luther University Halle-Wittenberg (MLU), together with ELANTAS, a division of the specialty chemicals group ALTANA, have developed a new process that enables the dyes to be directly integrated into the insulation. By changing colour, they reveal how much the insulating resin layer around the copper wires in the motor has degraded.
Scientists at the Tokyo Institute of Technology (Tokyo Tech) combine bipolar electrochemistry with a 1980s technique called electrolytic micelle disruption to produce patterned organic thin films. Their approach involves wirelessly inducing a desired potential distribution on a plate in an electrolytic cell to control the 'popping' of bubble-like micelles, which release their cargo to automatically form a film. Customized thin films produced with this inexpensive strategy could unlock applications in sophisticated biosensor systems and optoelectronics.
Researchers have developed a tool to help governments and other organizations with limited budgets spend money on building repairs more wisely.
Imagine an entire twenty storey concrete building which can store energy like a giant battery. Thanks to unique research from Chalmers University of Technology, Sweden, such a vision could someday be a reality. Researchers from the Department of Architecture and Civil Engineering recently published an article outlining a new concept for rechargeable batteries - made of cement.
Workers with blood lead levels below the legal ceiling in Brazil expressed a microRNA associated with a decrease in DNA methylation, a physiological process required for the organism to be in balance. However, known clinical manifestations occur when levels are high.
Scientists at Skoltech Center for Energy Science and Technology have developed an enriched and scalable approach for increasing the capacity of a broad range of metal-ion battery cathode materials. An important advantage of the approach is its scalability. The process requires no sophisticated conditions and is relatively safe. Additionally, the reducing agents can be recycled after they react with the cathodes because their redox chemistry is reversible. These features make the method promising for large-scale applications.
In a recent study, Dr. Park's group explored a feasible solution to the problem of using clathrate hydrates as vessels for H2 storage. However, the enclathration of pure H2 is still a slow process. To improve upon this strategy, the team set out to find the best hydrogen-natural gas blend (HNGB) for the energy-efficient formation of clathrate hydrates. They carefully analyzed the clathrate formation kinetics and structure and the distribution of trapped molecules.
A valve invented by engineer Nikola Tesla a century ago is not only more functional than previously realized, but also has other potential applications today, a team of researchers has found after conducting a series of experiments on replications of the early 20th-century design.
POSTECH research team led by Junsuk Rho presents a nanophotonics-based ultracompact LiDAR technology in a world-renowned journal.
