Laser‐Assisted Phase Engineering of 2D MoS2 for Efficient Solution‐Processed Electronics

Advanced Materials, EarlyView.
Here, local laser‐assisted phase transition from solution‐processed phase‐pure 1T′ to 2H MoS2 is shown to critically depend on the irradiation atmosphere. While processing in air leads to damaged insulating regions, inert conditions yield semiconducting 2H domains, enabling direct field‐effect transistor patterning with optimized lateral 1T′‐2H MoS2 ...

Unveiling Exsolution‐Induced Giant Electronic and Magnetic Property Changes in Non‐Stoichiometric Titanate Perovskite Thin Films

Advanced Materials, EarlyView.
A giant insulator to metal transition and emergent superparamagnetism are revealed by nanoparticle exsolution in non‐stoichiometric titanate perovskite thin films. By combining transport, synchrotron spectroscopy, and first‐principles calculations, this work reveals how defect reconfiguration and lattice reconstruction fundamentally reshape electronic ...

Hydrogen Atom Time-Element Volume–Orbit Paradigm Manifesto

We propose a time-element volume–orbit paradigm for the hydrogen atom, replacing the conventional Coulomb–wavefunction narrative with an ontological description built on a proton “time element” and a time-potential landscape. Electron motion is defined as a stable closure layer in this landscape rather than a force-balanced trajectory, a de Broglie ...

Recent Progress in the Phase‐Controlled Synthesis of Ruthenium Nanocrystals for Catalytic Applications

Advanced Materials, EarlyView.
Template effect and kinetic control enable crystal‐phase engineering of Ru nanocrystals, granting access to either metastable fcc‐Ru or stable hcp‐Ru with distinct surface structures, thermal stabilities, and catalytic behaviors. Moreover, the hcp‐Ru can further serve as an epitaxial template to direct Pd and Rh nanocrystals into the metastable hcp ...

A new European energy policy paradigm revealed by changes in hydrogen strategies

Energy Policy
As energy policy paradigms change, profound shifts in policy goals and instrument logics follow. Therefore, understanding when the energy policy paradigm might be changing is very important for researchers assessing energy policies. Although changes in policy paradigms are infrequent, they are more likely to occur during crises such as the 2022 energy ...
