Large‐Area Metallic Nanohelices for Engineering Optical Chirality

Small, EarlyView.
By exploiting the nanoscale engineering of residual stresses in metallic thin films, this method enables scalable fabrication of submicrometer metallic helices with tunable geometry and material versatility. The resulting structures exhibit pronounced chiroptical responses across the mid‐ to near‐infrared range, offering a robust platform for chiral ...

Comparison of the Prevalence of Bovine Leukemia Virus (BLV) in Holstein and Angus Cattle Breeds From Shandong Province, China

Microbiology and Immunology, EarlyView.
ABSTRACT Bovine leukemia virus (BLV) is widespread globally and causes economic losses in the cattle industry. Shandong Province plays a significant role in China's livestock industry, with an increasing importance in food of Holstein and Angus cattle. However, BLV prevalence in Holstein and Angus breeds in Shandong Province remains unclear.

Reconfigurable Metamirrors Based on Compliant Mechanisms

Advanced Functional Materials, Volume 36, Issue 10, 2 February 2026.
Providing the basis for numerous practical applications, the reconfigurability of metadevices is of great importance. Through the integration of controlled mechanical deformation with chiral meta‐atoms, a compliant mechanism based metamirror is demonstrated for active control over the polarization of electromagnetic waves.
