De-‘SCRIBE’-ing improvements—researchers refine procedure for printing gradient refractive index optics

Significant progress in creating optics with nonuniform (gradient) refractive indices has been made over the past two decades. In 2020, researchers at the University of Illinois Urbana-Champaign proposed a unique way to use direct laser writing to achieve even greater control over the refractive index. A new open-access paper details refinements to their so-called SCRIBE method.

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

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

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.
