Validation of Droplet Digital Polymerase Chain Reaction for Salmonella spp. Quantification
Frontiers in Microbiology, 2020 Salmonellosis is a foodborne disease caused by Salmonella spp. Although cell culture is the gold standard for its identification, validated molecular methods are becoming an alternative, because of their rapidity, selectivity, and specificity.

Advanced Functional Materials, Volume 36, Issue 25, 26 March 2026.The study explores structural and magnetic properties of one of the most recent topological quantum materials (MnBi2Te4). The Mn‐poor structure leads to stacking faults (quintuple layer ‐ QL of Bi2Te3 formation instead of a septuple layer ‐ SL of MnBi2Te4), resulting in a coexistence between weak antiferromagnetism and ferromagnetism.

Plasmonic Bi‐Cavity Nanostructure for Efficient Light Collection and Localization
Analysis &Sensing, Volume 6, Issue 2, March 2026.Co‐tuning the plateau and pyramid lengths of a pyramid‐on‐plateau nanostructure creates a hybrid antenna‐cavity that efficiently couples low‐NA excitation and funnels energy to the apex, increasing nano‐Raman signal and enabling TERS in geometries previously inaccessible to high‐NA objectives.Tip‐enhanced Raman spectroscopy (TERS) typically relies on ...

Establishment of 350–450 kV wide spectrum and high air‐kerma rate X‐ray radiation mass
The Journal of Engineering, Volume 2019, Issue 23, Page 8824-8828, December 2019., 2019 In recent years, the measurement of X‐rays has attracted much attention. Especially in the aspects of environmental monitoring, radiation protection, and radiation therapy, to obtain more accurate measurement values, it is necessary to set up a corresponding reference device to trace the magnitude.
