Concurrently Achieving 4.6 W/M² and 120,000 Cyclability Enabled by Extendable Swing Arms in Rotational Triboelectric Nanogenerator. [PDF]

Adv Sci (Weinh)
A rotational energy harvesting device that successfully reconciles high power density with mechanical durability through a hybrid sliding‐and‐bouncing kinematic mechanism is reported. The success reported in our paper includes addressing a dilemma where enhanced electrical output comes at the cost of increased friction and wear, limiting the practical ...

Efficient Harvesting of Irregular and Low-Frequency Mechanical Energy via Hybridized Electromagnetic-Triboelectric Systems. [PDF]

Small
ABSTRACT The rapid expansion of the Internet of Things (IoT) and wearable electronics necessitates sustainable power sources to replace the limited electrochemical battery. While mechanical energy harvesting offers a promising solution, traditional harvesters face challenges of irregular and low−frequency environmental sources. This review presents the

High-Speed, Maneuverable, and Terrain-Adaptive Micro-Robot with Tree Frog-Inspired Bionic Feet. [PDF]

Adv Sci (Weinh)
A 7.5 mm micro‐robot integrates tree frog‐inspired bionic feet with an electromagnetic linear motor to achieve high‐speed locomotion, slope climbing, and precise turning. It reaches 39 body lengths per second and ascends 30° slopes. The system demonstrates strong potential for inspection tasks in confined and complex environments, such as micro‐aero ...

Vibrational Exfoliation of 2D Materials

Small, EarlyView.
Vibrational energy folds, fractures and exfoliates atomically and molecularly thin materials. Combining experimentation and computational methods, this unique vibrational synthesis pathway is revealed. This process overcomes barriers of existing approaches by processing 1000 g/L dispersions without loss in yield.

Capability and Limitations of a Tuned Mass Damper for a 15‐MW Semisubmersible Floating Wind Turbine

Wind Energy, Volume 29, Issue 11, November 2026.
ABSTRACT Large floating offshore wind turbines (FOWTs) under coupled aerodynamic and hydrodynamic loading exhibit broadband low‐frequency response in addition to the platform‐pitch resonance. Tuned mass dampers (TMDs) have been studied for a range of applications, but their net benefit under fully coupled operational conditions has not been quantified.

Drought and Freezing Compromise Woody‐Plant Functioning in High Mountain Ecosystems Under Mediterranean Climate: The Case of Bencomia exstipulata

Physiologia Plantarum, Volume 178, Issue 4, July/August 2026.
ABSTRACT Bencomia exstipulata is a broad‐leaved evergreen shrub endemic to the high‐altitude harsh landscapes of the Canary Islands. Whether the extremely reduced distribution of its wild specimens (at around 2000 m a.s.l. in the National Parks of ‘El Teide’ and ‘Caldera de Taburiente’) responds to specific microclimatic needs remains undetermined ...
