Going Deep into the Surface Chemistry of Carbon Dots: Influence of Functional Groups on the Redox Abilities

open access: yesSmall, EarlyView.
The chemical structure of Carbon Dots (CDs) is still a mystery despite years of study. Herein, we show how CDs with a higher density of surface‐accessible amines display enhanced (photo)redox performance. Electrochemical and thermodynamic analyses confirmed the feasibility of electron transfer, while mechanistic investigations revealed that the ...

Precision Stress Engineering in Tensegrity‐Inspired Nanoarchitectures Enabled by Size‐Affected Shrinkage

open access: yesSmall, EarlyView.
This work identifies a size‐dependent shrinkage effect that arises during polymer pyrolysis and uses it to embed residual stress into tensegrity‐inspired nanoarchitectures. By adjusting the dimensions of the structural elements, controlled prestress can be introduced in a simple and repeatable manner, enabling mechanically tunable nanostructures with ...

Rapid Mechanochemical Synthesis of Oxyhalide Superionic Conductor: Time‐Resolved Structural Evolution

open access: yesSmall Methods, EarlyView.
Time‐resolved synchrotron X‐ray scattering coupled with mechanochemical synthesis reveals the structural evolution of oxyhalide superionic conductors. Oxygen incorporation governs reaction kinetics, amorphization, and microstructural transformations, while enabling efficient Li‐ion diffusion. This study highlights critical correlations between reaction

Advances in cholesterol and lipoproteins detection for healthcare: A review

open access: yesVIEW, EarlyView.
Cholesterol is one of the main biomarkers related to the development of cardiovascular diseases. Its detection still relies on traditional methods of analysis, such as gas and liquid chromatographies. Detection of free cholesterol in saliva with redox or enzymatic sensors or detection of lipoproteins in blood with aptamer sensors are currently the most

AI‐enabled bumpless transfer control strategy for legged robot with hybrid energy storage system

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
Abstract Designing Hybrid energy storage system (HESS) for a legged robot is significant to improve the motion performance and energy efficiency of the robot. However, switching between the driving mode and regenerative braking mode in the HESS may generate a torque bump, which has brought significant challenges to the stability of the robot locomotion.
