Light waves, radio waves and photons [PDF]
Physics Bulletin, 1960 In 1900 Planck solved the problem of constructing a formula to represent the distribution in energy of the radiation in a uniform temperature enclosure. The formula he obtained seemed to imply that the exchange of energy between the radiation field and the walls of the enclosure must take place in discrete amounts or quanta, the size of the quantum at ...

Network Topology Governs Photocatalytic Water Splitting in Organic Two‐Dimensional Crystals
Advanced Functional Materials, EarlyView.Network topology in organic two‐dimensional crystals (O2DCs) dictates the photocatalytic water splitting performance. Kagome‐lattice O2DCs exhibit strong electron‐hole mass asymmetry, spatially separated carriers, and longer recombination lifetimes, exceeding rhombic isomers.

Advanced Functional Materials, EarlyView.Carbon dots‐supported single‐atom catalysts provide a model platform for uncovering how coordination interactions regulate catalytic reactivity. Thiol binding at Ru‒N4 centers reshapes the reaction energy landscape of H2O2 activation, dynamically modulating ROS‐generation pathways through electronic‐structure perturbation.
