Toward lead-free piezoelectrics: KNN-based ceramic demonstrates enhanced electrical properties thanks to two-step sintering process
Awareness of lead’s toxicity drives research on alternative lead-free piezoelectric materials. But traditional high-temperature sintering processes can inadvertently deteriorate a lead-free ceramic’s piezoelectric response. A two-step sintering process can minimize this deterioration, and researchers in China identified the optimum temperature and dwell time for the first step.

The Animal Locomotion series by Eadweard Muybridge is a set of glass photographic plates that are widely regarded as the immediate predecessor to the development of motion pictures. Researchers from the Smithsonian Museum Conservation Institute investigated how formation of an amorphous surface layer on the glass plates due to water exposure can impact delamination of the image-containing gelatin layer.
