A CoCrFeNiTa0.4 eutectic high‐entropy alloy achieves a near‐theoretical yield strength of 2.6 GPa with 13.6% plasticity. This breakthrough stems from a hierarchical nanostructure (FCC‐Laves lamellae with L12/D022 precipitates), which alleviates the inter‐phase modulus/hardness mismatch through synergistic strengthening and toughening, guiding the ...

A gallium vanadium oxide (GVO)‐based free‐standing electrode is fabricated via a two‐step process involving a wet ball mill followed by thermal treatment and the surface‐engineered tape casting technique. The resulting GVO‐based free‐standing composite electrode has been successfully utilized for four distinct energy storage applications without any ...

Small dose monitor based on silicon‐carbide diodes for FLASH radiotherapy
Abstract Background The FLASH biological effect in radiotherapy has been observed to appear at ultra‐high dose rates UHDR (>$>$40 Gy/s), where the accurate dosimetry at such high rates is still a challenge. Purpose A new 4 ×$\times$ 4 array of SiC‐based detectors (1 mm diameter, 2.2 mm pitch) is proposed for dosimetry in UHDR, as well as the ...

Near‐surface divacancy defects in cubic silicon carbide exhibit modified properties due to surface‐induced symmetry breaking, as revealed by first‐principles calculations. The spin Hamiltonian is modulated by the defect's depth and orientation, providing key insights for engineering robust SiC‐based quantum devices and nanoscale sensors.

Intrinsic origin of electron scattering at 4H-SiC(0001)/SiO$_2$ [PDF]
We introduce a first-principles study to clarify the carrier-scattering property at the SiC/SiO$_2$. Interestingly, the electron transport at the conduction-band edge is significantly affected by the introduction of oxygen, even though there are no ...

Deep Learning Atmospheric Models Reliably Simulate Out‐of‐Sample Land Heat and Cold Wave Frequencies
Abstract Deep learning (DL)–based general circulation models (GCMs) are emerging as fast simulators, yet their ability to replicate extreme events outside their training range remains unknown. Here, we evaluate two such models—the hybrid Neural General Circulation Model (NGCM) and purely data‐driven Deep Learning Earth System Model (DLESyM)—against a ...

Investigation of Nanocutting Characteristics of Off-Axis 4H-SiC Substrate by Molecular Dynamics
Silicon carbide (SiC), especially 4H-SiC, is an ideal semiconductor in power electronics due to its outstanding electrical and thermal properties. It has high hardness and brittleness, which makes it difficult to machine.
