Advanced Science, EarlyView.The rare‐earth intermetallics YAuGe is identified as a Kramers nodal‐line semimetal, a topological state inherent to non‐centrosymmetric achiral lattices. Magnetic rare‐earth substitution induces an anomalous Hall effect, highlighting the impact of time‐reversal symmetry breaking on topological electronic states and offering insights into designing the

Advanced Science, EarlyView.The universality of the landscape‐flux theory with the mode expansion method for analyzing spatial patterns is illustrated by applying it to vegetation patterns in semi‐arid ecosystems. The framework quantifies global dynamics and most probable transition pathways between ecosystem states under random forcing.

Advanced Science, EarlyView.By integrating Cu/Cu2O and CoNi LDH, tandem kinetic descriptors, including a volcano curve, are employed to predict rate constants, facilitating ideal kinetic matching for efficient ammonia synthesis. The highest ammonia yield (1.12 mmol cm−2 h−1) and Faraday efficiency (99.78%) are achieved by rate matching between Cu/Cu2O and MoO4‐CoNi LDH.

Advanced Science, EarlyView.An extremely rare type of organic biluminescent emission is reported that consists of delayed emission resulting from both the fluorescence (multi‐resonance thermally activated delayed fluorescence) and phosphorescence spectra at room temperature, and the lifetimes of the two processes exhibit opposing dependence with temperature.
