A Practical Guide to First‐Principles Calculations for Pseudocapacitive Materials: From Electrochemical Experiments to Atomistic Understanding

open access: yesChemElectroChem, Volume 13, Issue 20, 16 October 2026.
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

open access: yesChemSusChem, Volume 19, Issue 19, 14 October 2026.
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.

Establishing Atomic Coherence in Twisted Oxide Membranes Containing Volatile Elements

open access: yesAdvanced Materials, Volume 38, Issue 55, 1 October 2026.
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.

Discovery of Novel Materials with Giant Dielectric Constants via First‐Principles Phonon Calculations and Machine Learning

open access: yesAdvanced Intelligent Discovery, Volume 2, Issue 5, October 2026.
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.

Enhanced Energy Storage Performances of Ceramics Enabled by Local Lattice Disorder Based on High‐Entropy Strategy

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
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.
