Advances in Triboelectric Nanogenerators With Rotating Structure

Carbon Energy, Volume 8, Issue 2, February 2026.
The rotating TENG has been widely studied for its superiorities of simple structure, high efficiency, and stable output. This review introduced the four different principles of rotating TENG and offered a thorough summary for performance and application research through three‐level classification. Importantly, the current existing problems, challenges,

Reliability assessment of cyber physical distribution systems including sequential scenario simulation correction and recovery resource decisions

Energy Conversion and Economics, Volume 7, Issue 1, Page 37-49, February 2026.
Abstract With the deepening of research on smart grids, the distribution system has gradually evolved into a cyber‐physical distribution system (CPDS). The refined reliability modelling and assessment methods for CPDS are of great significance. This paper proposes an integrated reliability assessment framework combining distribution information system (

Bistable Photochromic Guest–Host Liquid Crystals for Rewritable and Switchable Photonic Devices

Advanced Functional Materials, Volume 36, Issue 8, 26 January 2026.
A photochromic DTCP‐based liquid crystal dye is incorporated into cholesteric liquid crystals (CLCs) to achieve optically and electrically tunable multistable states. In the open‐ring form, the system exhibits three electrically stable textures—planar, focal conic, and uniformly lying helix (ULH)—corresponding to reflective, scattering, and transparent

Design of a Low Profile, Unpowered Ankle Exoskeleton That Fits Under Clothes: Overcoming Practical Barriers to Widespread Societal Adoption

IEEE transactions on neural systems and rehabilitation engineering, 2019
Here, we present the design of a novel unpowered ankle exoskeleton that is low profile, lightweight, quiet, and low cost to manufacture, intrinsically adapts to different walking speeds, and does not restrict non-sagittal joint motion; while still ...

Targeted Airborne eDNA of an Invasive Wallaby: Effects of Sampler Type, Distance, and Environmental Conditions

Environmental DNA, Volume 8, Issue 1, January–February 2026.
Airborne eDNA detection of terrestrial vertebrates is influenced by sampler design, distance, and environmental conditions. Using a targeted qPCR assay, we show that active sampling and coarse‐particle filters significantly improve airborne detection of wallabies, with airborne eDNA detectable at 1 km distances and strongly modulated by sampler ...
