Modular Electronic Microrobots With Onboard Sensor‐Program‐Steered Locomotion

Advanced Intelligent Systems, EarlyView.
Modular electronic smartlet microrobots integrate ambient‐light energy harvesting, photodetection, programmable CMOS control, and bubble‐based actuation within a sub‐millimeter fold‐up architecture. A 58‐bit on‐board CMOS chiplet enables sensor–program steered switching between independently addressable actuators, achieving closed‐loop 2D navigation in

Metal‐free Hydrogen Generation from Seawater and Silicon Waste: A Circular Approach

Angewandte Chemie, EarlyView.
Hydrogen was rapidly generated directly from untreated seawater and polymeric Si waste without any transition metal catalyst. The in situ generated polymeric cross‐linked Si resin was completely depolymerized under mild conditions into chloro‐silane monomers.

Liquid Jetting‐Based Miniature Robotic Navigation in Confined Fluidic Spaces

Advanced Intelligent Systems, EarlyView.
We introduce a new class of liquid‐jetting‐based miniature robots (JetBots) ranging in size from mm‐to‐cm, featuring a unified approach in design, fabrication, and actuation. They demonstrate fast locomotion (30.3 cm/s), rapid steering (648.8°/s), and diverse functions, such as puncturing soft materials and unlimited cargo sampling and delivery, paving

Biomimetic Nanoparticle Delivering Colchicine to Target Endothelial Inflammation for Atherosclerosis Treatment

Advanced NanoBiomed Research, EarlyView.
Platelet membrane‐coated layered double hydroxide nanoparticles were engineered to target inflamed endothelium at early‐stage atherosclerosis and enhance therapeutic efficacy. The biomimetic platform improves stability, immune escape, and inflamed vascular cell targeting, resulting in reduced oxidative stress and downregulated adhesion molecules.

Exoplanetary Atmospheric Escape: Solving the Hot Jupiter Over-Evaporation Mystery

Recent discoveries suggest that a universal energy-suppression law may solve one of exoplanet science's persistent puzzles - why hot Jupiters like HD 209458b show significantly lower atmospheric mass loss than conventional models predict.

Electroenzymatic CO2 Fixation

Angewandte Chemie International Edition, EarlyView.
Electroenzymatic CO2 fixation enables energy‐efficient, highly selective synthesis of complex molecules. Unlocking its full potential requires fundamental understanding of electrode‐coupled reductases and carboxylases. This review critically discusses available enzymes, product scope, and key thermodynamic and kinetic considerations, highlighting ...
