Mechanical Properties and Testing Strategies for Two‐Photon Lithography: A Review of Current Practices and Emerging Challenges

Laser &Photonics Reviews, Volume 20, Issue 17, 3 September 2026.
Two‐photon lithography enables the fabrication of complex 3D microstructures with tunable mechanical properties spanning from soft hydrogels to rigid hybrid networks. This review summarizes how material composition, printing parameters, and post‐processing govern stiffness and viscoelasticity, highlighting advanced characterization methods and emerging

Lightweight Metal–Polymer Interpenetrating Phase Composites for Mechanical Reinforcement and Absorption‐Dominant Electromagnetic Interference Shielding

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT The pursuit of multifunctional lightweight materials with electromagnetic interference (EMI) shielding of low reflection, programmable architecture, and robust mechanical performance presents both significant opportunities and challenges. In this work, aluminum (Al)‐alloy lattice with 90% porosity was designed and fabricated using additive ...

Non‐Physical Barrier Design and Environmental Conditions Alter Routing and Survival of Juvenile Chinook Salmon (Oncorhynchus tshawytscha) in the Sacramento‐San Joaquin River Delta

River Research and Applications, Volume 42, Issue 7, Page 1551-1561, September 2026.
ABSTRACT Pacific salmon face substantial challenges when migrating through anthropogenically modified river systems, such as the Sacramento‐San Joaquin River Delta (the Delta). Non‐physical behavioral barriers, such as the bioacoustic fish fence (BAFF), are one potential solution for guiding fish away from hazards without obstructing water flow ...

Portable Radar for Noncontact Heart Rate Monitoring and Estrus Detection in Dairy Cows

IEEJ Transactions on Electrical and Electronic Engineering, Volume 21, Issue 9, Page 1390-1403, September 2026.
This study introduces a portable radar system for real‐time monitoring of respiratory and heart rates in dairy cows. It uses millimeter‐wave Frequency Modulated Continuous Wave (FMCW) radar to perform noncontact physiological sensing, reducing behavioral disturbance. The radar system's design prioritizes portability, cost‐effectiveness, and robustness,
