Direct Observation of Vortex Liquid Droplets in the Iron Pnictide Superconductor CaKFe4As4 at 0.5Tc

Advanced Science, EarlyView.
Vortex matter in the iron‐based superconductor CaKFe4As4${\rm CaKFe}_4{\rm As}_4$ is visualized at the nanoscale, revealing the unexpected emergence of vortex‐liquid droplets far below the critical temperature. These localized fluctuating regions coexist with a vortex solid, demonstrating that dissipation‐related dynamics arise well before macroscopic ...

Chemically Gradient Ordered Nanodomains Enable Large Tensile Ductility in Gigapascal Lightweight Refractory High‐Entropy Alloys

Advanced Science, EarlyView.
A high‐strength lightweight refractory high‐entropy alloy achieves extraordinary ductility owing to the introduction of coherent chemically gradient ordered nanodomains (CGONs). The CGONs not only serve as effective barriers to dislocation motion (strengthening) but also significantly promote dislocation nucleation and multiplication (ductilizing) upon

Charge‐Transfer‐Mediated Boron Magneto‐Ionics: Towards Voltage‐Driven Multi‐Ion Transport

Advanced Science, EarlyView.
This study demonstrates voltage‐driven multi‐ion transport in FeBO systems, revealing simultaneous motion of B, Fe, and O ions enabled by charge‐transfer effects. By tuning oxidation states through oxygen incorporation, we achieve a transition from electrostatic‐like to electrochemical magneto‐ionic behavior. The findings establish boron magneto‐ionics,

Conversion of fast neutrons for neutron radiography with TPX2 detector

Nukleonika
The Timepix2-based hybrid-pixel detector with a 500 μm thick silicon sensor was employed for fast-neutrons registration to be applied in neutron radiography of metallic printed circuit heat exchanger (PCHE).

Metal Battery Anode: Rich in Electrons, Rich in Problems: A Critical Review from Industrial Perspectives

Advanced Science, EarlyView.
Metal‐anode batteries using Li, Na, Mg, and Ca offer exceptionally high energy density, but dendrites, unstable interphases, cracking, and pore formation hinder durability and safety. This review shows how careful electrolyte and interphase design can stabilize these reactive metals.

Monte-Carlo Simulation of -ray and Fast Neutron Radiolysis of Liquid Water and 0.4 M H2SO4 Solutions at Temperatures up to 325oC

Atom Indonesia, 2011
Monte-Carlo simulations were used to study the radiolysis of liquid water at 25-325C when subjected to low linear energy transfer (LET) of 60Co -ray radiation and fast neutrons of 2 and 0.8 MeV.

Unveiling the Ultralow Thermal Conductivity of Hybrid Perovskites

Advanced Science, EarlyView.
In hybrid perovskites, thermal energy flows through lattice vibrations of the framework (48%–65%) and organic molecules (35%–52%). When the disorder introduced by organic molecules is excluded, the temperature dependence of the vibrational thermal conductivity results from the lattice framework transits from ∼T0 to ∼T−1, and the value doubles at room ...
