Cation Diffusion‐Mediated Displaced Reaction‐Transformation in Green Steelmaking

Advanced Science, EarlyView.
The removal of O lattice atoms by environmental H2 at the surface of Fe3O4 results in Fe enrichment, driving the inward diffusion of Fe cations into the bulk. Through hopping between unoccupied and initially occupied sites, cation diffusion triggers a spatially displaced reaction‐transformation and drives subsequent dynamic phase transformations and ...

The western submerged sector of the Ischia volcanic island (Tyrrhenian Sea, Italy): new insights into its volcano-tectonic evolution [PDF]

, 2010
The Island of Ischia is a volcanic complex located in the northern boundary of the Gulf of Naples (south-eastern Tyrrhenian Sea, Italy). The island represents only the 30% of a larger, E-W trending, volcanic ridge and likely controlled by a regional ...

Renal Clearable Luminogenic Reporter for Ultrasensitive Influenza Virus Imaging and Efficient Antiviral Therapies Monitoring in Living Mice

Advanced Science, EarlyView.
A viral luminogenic reporter with chemiluminescence/fluorescence dual‐response and efficient renal clearance was developed for non‐invasive imaging and urinalysis of H1N1 virus protease, allowing for remote detection of H1N1 virus infections and monitoring of antiviral therapeutic efficacy in living mice.

Bifurcation Phenomena of a Magnetic Island at a Rational Surface in a Magnetic-Shear Control Experiment [PDF]

Three states of a magnetic island are observed when the magnetic shear at the rational surface is modified using inductive current associated with the neutral beam current drive in the Large Helical Device.

Magnetic island effects, interactions in tokamaks [PDF]

, 1993
This paper explores a number of aspects of isolated and interacting magnetic islands, and their effects, in tokamak plasmas. The temperature fluctuations induced by an isolated magnetic island in a rotating tokamak plasma are shown to be surprisingly ...

Synchronized Imaging of Hydrogen Peroxide and Hydroxyl Radical in Pyroptosis and Epilepsy

Advanced Science, EarlyView.
A dual‐responsive fluorescent probe, HH, enables synchronized visualization of H2O2 and •OH through spectrally resolved green and red channels. By tracking redox dynamics in pyroptosis and epilepsy models, HH reveals ROS elevation during seizure‐like pathology and supports evaluation of antioxidant and antiepileptic therapeutic interventions.

Effects of edge-localized electron cyclotron current drive on edge-localized mode suppression by resonant magnetic perturbations in DIII-D

Nuclear Fusion
According to recent DIII-D experiments (Logan et al 2024 Nucl. Fusion 64 014003), injecting edge localized electron cyclotron current drive (ECCD) in the counter-plasma-current (counter- I _p ) direction reduces the n = 3 resonant magnetic perturbation ...

Terahertz‐Nanoscale Visualization of the Microscopic Spin‐Charge Architecture of Colossal Magnetoresistive Switching

Advanced Science, EarlyView.
This study employs cryogenic magneto‐terahertz nanoscopy to reveal the real‐space electrodynamics of the colossal magnetoresistance transition. By capturing the terahertz electrodynamic evolution of field‐driven spin switching, the work unveils the dissipative dynamics of emergent metallic states, providing a high‐frequency view of coupled spin‐charge ...

Observation of hysteretic magnetic island response to Resonant Magnetic Perturbation in LHD [PDF]

The hysteretic magnetic island response to an externally applied resonant magnetic perturbation (RMP) field is observed in the LHD. Thresholds of the amplitude of the RMP for the growth/healing transition of the magnetic island differ.
