Nonlinear Dynamics of a Resonant-Impact Dielectric Elastomer Actuator

Applied System Innovation, 2022
In recent years, with the rapid development of soft robots, dielectric elastomer actuators (DEAs) as a novel type of soft actuators have been widely studied. However, DEAs often suffer from low instantaneous output force/power, especially in high payload

Environmental DNA Biosurveillance of Chelonid Herpesvirus 5 (ChHV5) in Endangered Sea Turtles Around Singapore

Environmental DNA, Volume 8, Issue 3, May–June 2026.
This study explores the application of environmental DNA sampling for chelonid herpesvirus 5 (ChHV5) surveillance in endangered sea turtles around Singapore. We demonstrate the direct detection of ChHV5 from seawater, and the feasibility of sediment‐based ChHV5 detection using a spike‐and‐recovery experiment.

Reduction, Softening, and Melting Characteristics of Mill Scale‐Based Briquettes for Blast Furnace Ironmaking

steel research international, Volume 97, Issue 5, Page 2585-2599, May 2026.
The study evaluates mill scale‐based briquettes, which meet industrial standards for shatter strength and exhibit a low decrepitation index. Despite their limited reducibility in nonisothermal reduction experiments, softening and melting results indicate potential application as a substitute for conventional acidic iron‐bearing materials for use in ...

Olivine Microstructure Constraints on Ureilite Parent Body Deformation

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Ureilites are ultramafic achondrites for which the parent body is unknown. Monomict ureilites, consisting primarily of olivine and pyroxene, are thought to represent mantle residues, carrying essential information for their parent body deformation history.
