Stretching metals at the atomic level, fastest industry standard optical fiber, and other materials stories that may be of interest for May 31, 2023.
Read MoreVerifying the purity of ultrahigh-purity materials can be a challenge. Researchers in Italy and Norway developed a new analytical protocol based on laser ablation paired with inductively coupled plasma mass spectrometry to determine the purity of silicon carbide.
Read MoreGroup-III-nitride semiconductors have considerable potential for electronic and optoelectronic applications, but unintended defects tend to form in their structure during fabrication, which may affect the electrical properties. Two researchers at the University of British Columbia detailed the striking contrast between the effects of threading dislocation lines in gallium nitride versus indium nitride.
Read MoreAfter a series of delays, the United Kingdom finally announced its strategy, as well as a new Japanese partnership, for supporting the semiconductor industry. Details of these plans—as well as industry response so far—are given in today’s CTT.

Read MoreInnovation in medicine can be slower than in other fields to prevent putting patient safety at risk. Emergencies, however, can necessitate the adoption of new technologies. In an open-access paper, medical professionals in England described the use of a novel technique to extract a ceramic liner during hip revision surgery when established strategies proved ineffective.
Read MoreStarting materials can often be derived from different sources, but the impact that material source has on a product’s properties is generally less studied than other factors, such as synthesis technique. Researchers from Wuhan University of Technology explored the effect of different magnesium sources on the production of magnesium aluminate spinel.
Read MoreThere are many challenges to realizing a hydrogen economy that occur all along the supply chain. One challenge—converting the carrier molecule ammonia back into hydrogen—could be solved using solid acid fuel cells. ACerS Fellow Sossina Haile first developed this type of fuel cell in the late 1990s. Today’s CTT looks at Haile’s 20-year journey with her first Ph.D. student, Calum R. I. Chisholm, to realize the potential of this technology.
