Electrochemical experiments reveal what happens, whereas first principles calculations explain why. Emerging computational electrochemistry is bridging these perspectives, enabling quantitative understanding of electrode/electrolyte interfaces and enabling the rational design of next‐generation energy storage materials.

Hydrogenolysis of Aromatic Oxygenates Over Pt/WO3–ZrO2 in a Water/Decane Biphasic System
Combining a water‐tolerant Pt/WO3–ZrO2 catalyst with a water/decane biphasic system enables efficient hydrogenolysis of lignin‐derived aromatic oxygenates under mild conditions. Spatial separation of the catalyst and arene products suppresses over‐hydrogenation, providing high aromatic selectivity at only 90 °C and 0.1 atm H2.

Nb2O5 and Ti-Doped Nb2O5 Charge Trapping Nano-Layers Applied in Flash Memory
High-k material charge trapping nano-layers in flash memory applications have faster program/erase speeds and better data retention because of larger conduction band offsets and higher dielectric constants.

Establishing Atomic Coherence in Twisted Oxide Membranes Containing Volatile Elements
Twisted oxide membranes containing volatile elements often suffer from amorphous interfacial dead layers that suppress coupling. An oxygen‐annealing strategy establishes atomically coherent and chemically bonded interfaces in twisted NaNbO3 membranes, enabling coherent oxide moiré architectures in volatile‐element‐containing systems.

We discovered novel materials with giant dielectric constants by combining first‐principles phonon calculations and machine learning. Screening 525 perovskites identified six candidates. RbNbO3 was synthesized under pressure and showed ε ≈ 800–1000. This validates our framework as a powerful tool for high‐performance dielectric materials discovery.

ABSTRACT With the depletion of energy resources and the vigorous development of renewable energy technologies, the demand for efficient energy storage technologies has become increasingly urgent. Dielectric ceramics feature ultrafast charge–discharge speed, but low energy density and inferior efficiency hinder device miniaturization.
