Skyrmion Bubbles by Design in a Centrosymmetric Kagome Magnet

open access: yesAdvanced Science, EarlyView.
Chemical tuning of magnetocrystalline anisotropy in the centrosymmetric kagome magnet TmMn6Sn6 is shown to drive a spin reorientation transition via an intermediate magnetic fan state and to stabilize an emergent skyrmion bubble lattice. Four‐dimensional cryogenic Lorentz scanning transmission electron microscopy confirms the nanoscale texture ...

X-Ray Astronomy Satellite Ginga [PDF]

open access: yesInternational Astronomical Union Colloquium, 1988
AbstractThe X-ray astronomy satellite Ginga carries three scientific instruments, the Large Area proportional Counters (LAC), All Sky X-ray Monitor (ASM) and Gamma-ray Burst Detector (GBD). The LAC is the main instrument with an effective area of 4000 cm2 giving it the highest sensitivity to hard X-rays so far achieved. Ginga observed about 250 targets

A Single Volatile VO2 Memristor Enabling Neuromorphic Perception, Learning, and Computing

open access: yesAdvanced Electronic Materials, EarlyView.
A single volatile VO2 memristor fabricated via atomic layer deposition is demonstrated as a multifunctional neuromorphic device enabled by intrinsic threshold‐switching dynamics. The device reproduces neuron‐like integration and firing, short‐timescale associative learning, temporal ECG pattern classification, and nociceptive responses to electrical ...

Expectation for the Hard X-Ray and Gamma-Ray Emission from Pair-instability Supernovae

open access: yesThe Astrophysical Journal
Pair-instability supernovae (PISNe) are predicted thermonuclear explosions of massive stars with helium core masses exceeding ∼65 M _⊙ , and they synthesize substantial amounts of radioactive ^56 Ni ( M ( ^56 Ni) ∼ 60 M _⊙ in extreme cases).

Effects of 1 Gray radiation on the biophysical properties of the tibia and femur from hindlimb-suspended rats. [PDF]

open access: yesExp Physiol
Abstract Long‐term space travel (e.g. travel to Mars) will greatly exceed the recommended lifetime radiation dose of 600 millisieverts (mSv) and have a detrimental effect on skeletal fragility. Our objective was to determine if 1 Gray (GY) radiation impacts the biomechanical properties of the tibia and femur from rats under microgravity.

Covalently Locked Donor–Acceptor Block Copolymer Nanoparticles Enable Efficient, Stable and Reproducible Photocatalytic Hydrogen Evolution

open access: yesAdvanced Energy Materials, EarlyView.
To overcome the efficiency–stability trade‐off of traditional donor:acceptor blends, covalently locked all‐conjugated block copolymer nanoparticles are developed for solar hydrogen production. This strategy achieves an outstanding HER rate exceeding 120 mmol cm−2 g−1 h−1, alongside exceptional operational stability (95% retention after 96 h) and high ...
