High‐Performance Self‐Powered Sensing System for Power Grid Applications

Advanced Sensor Research, Volume 5, Issue 3, March 2026.
This study presents a lateral swing electromagnetic generator (LS‐EMG) for harvesting overhead transmission line vibration energy. With a compact 24.32 cm3 volume, it achieves 2.28 mW output power and 93.75 µW/cm3 power density. A self‐powered wireless sensor system was developed using this generator, enabling real‐time temperature and humidity ...

Study of Superlubricity

Hyomen Kagaku, 2003
Superlubricity, a phenomena of vanishing friction, has been studied theoretically and experimentally. It is theoretically shown that certain unique cases exist where friction force exactly vanishes when the atomic arrangements on the contacting surfaces satisfies the condition for the appearance of superlubricity.

Ions as Architects of DNA Nanostructures: Mechanisms, Simulations, and Technological Frontiers

Small Structures, Volume 7, Issue 3, March 2026.
Ions are not merely passive electrolytes but active regulators of DNA nanostructures. This review shows how ion valence, hydration, and specificity govern electrostatic screening, correlation, and confinement, enabling DNA origami, metallized DNA, nanopores, hydrogels, DNAzymes, molecular machines, and energy devices through integrated experimental and

The Promise of Solid Lubricants for a Sustainable Future

Advanced Materials, Volume 38, Issue 8, 6 February 2026.
Lubricants are vital for technology, saving energy and resources. The industry seeks sustainable solutions beyond fossil fuels. Solid lubricants offer extremely low friction and reduce environmental impact, especially in harsh conditions. Can these solids truly replace liquid lubricants, or are they limited to extreme applications?

Adhesive Tape‐Inspired Polymer Coatings Enable Record‐Stable Zinc Anodes for High‐Rate Aqueous Batteries

Advanced Science, Volume 13, Issue 10, 18 February 2026.
An adhesive tape–inspired anode stabilization strategy is proposed by grafting poly(methyl methacrylate) onto natural rubber. The resulting copolymer coating exhibits elasticity, adhesion, and ion‐selective nanodomains, which lower Zn2+ desolvation barriers, guide deposition to the stable (002) facet, and ensure intimate interfacial contact, delivering
