A Resistive Soft Robotic Exosuit for Dynamic Body Loading in Hypogravity

Advanced 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 ...

Chaotic Combustion in Spark Ignition Engines

, 2002
We analyse the combustion process in a spark ignition engine using the experimental data of an internal pressure during the combustion process and show that the system can be driven to chaotic behaviour.

Constructing Dual‐Atomic Fe─Fe Sites Nanozyme for Targeted Osteoarthritis Therapy through Mitigating Oxidative Stress and Cartilage Degeneration

Advanced Science, EarlyView.
A novel bimetallic nanozyme (Fe2–NCs) with well‐defined Fe–Fe active sites is synthesized through a host–guest coordination strategy, which exhibits an exceptional therapeutic efficacy in osteoarthritis therapy. Experimental and theoretical analyses uncover the intrinsic catalytic mechanism at the atomic level, offering fundamental insights and design ...

Local heat flux measurement technique for internal combustion engines [PDF]

, 2017
The heat transfer from the combustion gases to the cylinder wall affects the efficiency, emissions and power output of an internal combustion engine. Measuring the heat transfer requires a heat flux sensor inside the combustion chamber that has a short ...

Edible Pneumatic Battery for Sustained and Repeated Robot Actuation

Advanced Science, EarlyView.
This work presents an edible energy source and valve system to power soft, pneumatically driven edible robots. A chemical reaction between sodium bicarbonate and citric acid generates carbon dioxide gas, and a pressure‐triggered edible valve enables self‐repetitive motion of the edible actuator.
