Video: Upcoming deadline risks deep-sea mining taking place without regulations

By Lisa McDonald / May 31, 2023

The International Seabed Authority is running up against a July 9 deadline to finish developing a code for deep-sea mining. The possibility of mineral exploitation taking place without regulations has marine scientists concerned because so much is still unknown about the environmental effects of this practice.

A charged finding—effect of threading dislocation lines on conductivity in gallium nitride versus indium nitride

By Lisa McDonald / May 26, 2023

Group-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.

Innovating in emergencies: A novel technique for removing ceramic liners in hip revision surgery

By Lisa McDonald / May 23, 2023

Innovation 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.

Singling out discrepancies: The effect of magnesium source on a ceramic’s final properties

By Lisa McDonald / May 19, 2023

Starting 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.

Video: Solid acid fuel cells—a 20-year journey to advancing the hydrogen economy

By Lisa McDonald / May 17, 2023

There 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.
