A new method improves the extraction and separation of rare earth elements—a group of 17 elements critical for technologies such as smart phones and electric car batteries—from unconventional sources.
Gold is one of the world's most popular metals. Malleable, conductive and non-corrosive, it's used in jewelry, electronics, and even space exploration.
A multidisciplinary team of scientists has used the National Synchrotron Light Source II, a U.S. Department of Energy Office of Science User facility located at the DOE's Brookhaven National Laboratory, to investigate how high-temperature molten salts corrode metal alloys.
Left- or right-handedness is a symmetry property that many macroscopic objects also exhibit and which is of immense importance, particularly for the bioactivity of organic molecules.
Chinese scientists have made direct observations in face-centered cubic VCoNi (medium)-entropy alloys (MEA) and for the first time proposed a convincing identification of subnanoscale chemical short-range order (CSRO).
A thermos bottle has the task of preserving the temperature - but sometimes you want to achieve the opposite: Computer chips generate heat that must be dissipated as quickly as possible so that the chip is not destroyed. This requires special materials with particularly good heat conduction properties.
Superalloys that withstand extremely high temperatures could soon be tuned even more finely for specific properties such as mechanical strength, as a result of new findings published today.
Alchemy, which attempted to turn cheap metals such as lead and copper into gold, has not yet succeeded. However, with the development of alloys in which two or three auxiliary elements are mixed with the best elements of the times, modern alchemy can produce high-tech metal materials with high strength, such as high entropy alloys.
Nitrous oxide (N2O), similar to its chemical relative carbon dioxide (CO2), is a major greenhouse gas and is also the leading ozone-depleting substance produced in the 21st Century.
The periodic table—an arrangement of the elements that helps identify and estimate the trends in their properties—is taught to all chemistry students.
