Advanced Optical Materials, EarlyView.The epsilon‐near‐zero (ENZ) effect in metals emerges only in nanometer‐scale films with exceptional optical quality. Titanium nitride (TiN) films grown by molecular beam epitaxy retain high crystallinity down to 2 nm and exhibit dramatically enhanced nonlinear optical responses near the ENZ region.

NIR I‐to‐NIR I Time‐Gated Luminescence Detection From Tm3+‐Doped Gd3TaO7 for Deep Tissue Imaging
Advanced Optical Materials, EarlyView.A new generation of optical imaging (OI) using temporal resolution, exploring a NIR I‐to‐NIR I biological window emission by a Phonon Assisted Conversion (PAC) system singly doped with Tm3+ ions. Although still in early development, this approach opens new directions for designing optimized fluorophores to enhance bioimaging performance.

Advanced Science, EarlyView.We elucidate the key roles of metal p‐d orbital hybridization, excited‐state metal–ligand π‐interactions, and structural rotation in TADF of d10 CMA complexes. Introducing electron‐withdrawing or π‐extended ligand substituents weakens excited‐state metal‐ligand π‐interactions and improves kTADF, but may compromise emitter stability in device operation.

The Beneficial Effects of Krypton Inhalation Following Traumatic Brain Injury in Rats
Общая реаниматологияTraumatic brain injury (TBI) remains one of the leading causes of disability, and current approaches to neuroprotection have limited efficacy. The inert gas krypton is considered a promising neuroprotective agent; however, data on its effects in TBI and ...

Advanced laboratory for testing plasma thrusters and Hall thruster measurement campaign
Nukleonika, 2016 Plasma engines are used for space propulsion as an alternative to chemical thrusters. Due to the high exhaust velocity of the propellant, they are more efficient for long-distance interplanetary space missions than their conventional counterparts.

A Ceramic Network for Hybrid Solid Electrolyte Lithium Metal Batteries
Advanced Science, EarlyView.An in‐plane aligned Ta‐LLZO ceramic network exhibits superior performance compared to conventional fillers, including single ceramic fibers and particles. The tortuosity within the polymeric phase of hybrid solid electrolytes is identified as a key parameter governing lithium‐ion transport pathways and dendrite suppression.

AIP Conference Proceedings, 2013 Phase transitions of pure substances provide the key reference temperatures, otherwise known as "defining fixed points", of the International Temperature Scale. At temperatures below the triple point of mercury (234.3156 K), the substances involved are gases at room temperature and include the triple points of hydrogen (13.8033 K), neon (24.5561 K ...
