Closing the Loop: High‐Precision 3D Photofabrication in Living Tissues
Writing 3D microstructures inside living tissue demands more than laser access; It demands information. Hierarchical sensing captures thermal and mechanical states across pulse‐train, voxel, and structure timescales, feeding a controller that steers the laser in real time.

A Fresh Look at Entropy and the Second Law of Thermodynamics
The existence of entropy and its increase can be understood without reference to either statistical mechanics or heat engines. In days long gone, the second law of thermodynamics (which predated the rst law) was regarded as perhaps the most perfect and

A rational, solvent‐free synthesis utilizing 2,6‐diaminonaphthalene produces ultrabright green‐emissive carbon dots. Regulated by a self‐limiting oxidative capping mechanism, excitons undergo ultrafast intra‐particle funneling from the nitrogen‐doped carbon core to emissive surface traps.

Multiscale phase segregation in block copolymers enables spatially deterministic structuring from molecular to macroscopic scales, decoupling solar scattering and infrared emission for augmented radiative cooling. ABSTRACT Passive radiative cooling, which reflects solar irradiation while emitting heat through the atmospheric window, provides a ...

Existing machine learning potentials remain limited in their ability to generalize across the broad chemical and structural variability of C–S–H. Here, a representative DFT‐labeled dataset is constructed through large‐scale model generation, redundancy‐controlled screening, first‐principles optimization, and targeted sampling of non‐equilibrium ...

Scalable synthesis of single‐crystal mid‐nickel cathodes demands precise kinetic control over competing densification and grain growth. Oxygen partial pressure emerges as a quantitative descriptor of effective grain‐boundary mobility, acting through changes in the apparent sintering activation barrier.
