Worldwide efforts to make sodium-ion batteries just as functional as lithium-ion batteries have long since controlled sodium's tendency to explode, but not yet resolved how to prevent sodium-ions from 'getting lost' during the first few times a battery charges and discharges. Now, Purdue University researchers made a sodium powder version that fixes this problem and holds a charge properly.
A research team from the NUST MISIS Department of Pressure Metal Treatment has developed a new technology which simplifies the process of hot rolling seamless pipes made of alloy and high-alloy steel. The consistent use of two simple male punches, tools that turn an unruly steel blank into a hollow "sleeve", is a distinctive feature of the technology.
Water covers most of the globe, yet many regions still suffer from a lack of clean drinking water. If scientists could efficiently and sustainably turn seawater into clean water, a looming global water crisis might be averted. Now, inspired by origami, the Japanese art of paper folding, researchers have devised a solar steam generator that approaches 100 percent efficiency for the production of clean water. They report their results in ACS Applied Materials & Interfaces.
Osaka University researchers prepared 2D layered, visible-light-absorbing bismuth sulfide semiconductors using a two-step process. The resulting film exhibited morphology that supported excellent semiconductor performance. The simplicity and versatility of the processing method, which uses non-toxic, abundant materials, makes bismuth sulfide a viable alternative to commercially available photoresponsive devices.
Researchers from Ekaterinburg, Russia, have developed and tested a new solid oxide electrolysis cell. They observed increased performance of the cell when the reducing atmosphere was enriched with carbon dioxide.
Physicists from the Institute for Solid State Physics at the University of Tokyo have generated the strongest controllable magnetic field ever produced. The field was sustained for longer than any previous field of a similar strength. This research could lead to powerful investigative tools for material scientists and may have applications in fusion power generation.
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.
