Cut‐Enabled Mechanical Metamaterials for Multimodal and Reprogrammable Static Nonreciprocity

open access: yesAdvanced Science, EarlyView.
Cut‐enabled mechanical metamaterials are designed to overcome the challenge of obtaining multiple and reprogrammable static nonreciprocal modes in a single microstructural topology. It offers a pathway to synthesize multiple nonreciprocal modes and control the nonreciprocal responses, enhancing the functionality of metamaterials.

A Resistive Soft Robotic Exosuit for Dynamic Body Loading in Hypogravity

open access: yesAdvanced Science, EarlyView.
The resistive hypogravity exosuit is a lightweight wearable robotic exosuit that uses pneumatic artificial muscles to restore Earth‐like metabolic and muscular demands during locomotion in low gravity. Tested on healthy subjects in Earth and simulated Moon gravity, the suit restores energy expenditure and muscle activation without altering gait ...

Evidence for Nonlinear Diffusive Shock Acceleration of Cosmic Rays in the 2006 Outburst of RS Ophiuchi

open access: yes, 2007
Spectroscopic observations of the 2006 outburst of RS Oph at both infrared (IR) and X-ray wavelengths have shown that the blast wave has decelerated at a higher rate than predicted by the standard test-particle adiabatic shock-wave model.

Nanofluid‐Enhanced Laser Lithotripsy Using Conducting Polymer Nanoparticles

open access: yesAdvanced Science, EarlyView.
Incorporating polymeric nanoparticles, PEDOT:PSS, with a high near‐infrared absorption coefficient into the fluid significantly enhances the dusting efficiency of Ho:YAG laser lithotripsy for kidney stone treatment. This approach, which leverages the control of light‐matter interactions, integrates seamlessly with the current laser lithotripsy workflow.
