Advanced Science, EarlyView.This study investigates how the internal structure of fiber‐reinforced ceramic composites affects their resistance to damage. By combining 3D X‐ray imaging with acoustic emission monitoring during mechanical testing, it reveals how silicon distribution influences crack formation.

Advanced Science, EarlyView.Trace water transforms from an impurity to a design handle for ternary organic solar cells. During solvent evaporation, minimal amounts organize transient hydrogen‐bonding networks that steer component migration and set the morphology. The mechanism enables reproducible morphology locking and identifies a practical co‐solvent threshold near H2O:CF = 0 ...

Evaluation of European regional reanalyses and downscalings for precipitation in the Alpine region
Meteorologische Zeitschrift, 2015 Datasets of the observed weather and climate on a regular grid are an important requisite for environmental and climate change research. In this paper we evaluate several European-scale regional reanalyses, developed in the EU project EURO4M, and compare

Current dependence of grain boundary magnetoresistance in La_0.67Ca_0.33MnO_3 films
, 1999 We prepared epitaxial ferromagnetic manganite films on bicrystal substrates by pulsed laser ablation. Their low- and high-field magnetoresistance (MR) was measured as a function of magnetic field, temperature and current.

Stress‐Induced Melting Controlled Failure Mechanisms of Methane Hydrate
Advanced Science, EarlyView.We study methane hydrate via nanoindentation and nuclear magnetic resonance (NMR), finding its regional melting and mechanical properties, challenging existing views on hydrogen‐bonded crystals. Abstract Methane hydrate, a kind of nonstoichiometric crystalline, attracted worldwide attentions as a promising substitute energy. Its Dissociation is thought

Advanced Science, EarlyView.A novel strategy is developed by doping reduced graphene oxide (rGO) into a (HfZrTi)C medium‐entropy ceramic. This induces a hierarchical strain modification mechanism, synergistically inhibiting crack propagation at the microscale and dissipating stress at the mesoscale.

Dilute but Dense – Reversible Crosslinking Enables Water‐Rich (Bio)polymer Condensates
Advanced Science, EarlyView.Reversible crosslinking between two types of (bio)polymers drives liquid–liquid phase separation even in good solvent. The arrangement of binding motifs controls condensate formation and density, and internal network structure. Simulations and theory reveal a closed‐loop coexistence phase diagram at very low monomer concentrations and re‐entrant ...

Advanced Science, EarlyView.Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...
