Giant Topological Hall Effect Across a Broad Temperature Window in Co‐Doped Mn3Sn Noncoplanar Antiferromagnets

open access: yesAdvanced Science, Volume 13, Issue 44, 7 August 2026.
Co doping in Mn3Sn transforms the spin texture magnetic state from a coplanar noncollinear magnetic state into a noncoplanar one, resulting in a large topological Hall effect (THE) over a wide temperature range (2–300 K). The THE arises from a noncoplanar spin texture, driven by lattice distortion and enhanced out‐of‐plane Dzyaloshinskii ...

Rare‐Earth Yttrium Doping Advances High‐Performance AgSbTe2 Thermoelectrics

open access: yesAdvanced Energy Materials, Volume 16, Issue 30, 12 August 2026.
Y‐doped AgSbTe2 achieves band and microstructure co‐optimization, with coherent Y‐Ag2Te interfaces enhancing phonon scattering and reducing lattice thermal conductivity to 0.26 W m−1 K−1. Combined with valence‐band broadening and increased carrier concentration, this yields ZT ≈ 2 at 623 K, average ZT = 1.5, and 7.3 % conversion efficiency of a single ...

Hunting Active Sites for CO Oxidation on CO‐covered Pd(100) With Bat Vision Ambient Pressure X‐ray Photoelectron Spectroscopy

open access: yesChemCatChem, Volume 18, Issue 15, 14 August 2026.
To selectively detect minority sites and measure their catalytic properties is challenging. As the bat uses the echo of insects to locate them in darkness, we here demonstrate that the echo‐signal of small temperature modulations applied to a catalyst can be used to reveal minority sites.

Abnormal Phase Transition Mechanism in the CoCrAlY Bond Coat Revealed by In Situ and Ex Situ Experiments

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT In Co‐based alloys, the γ phase is normally stable at high temperatures and the ε phase at low temperatures, and there is a martensitic transition on cooling to ∼417°C. In the γ/β dual‐phase CoCrAlY bond coat of turbine blade thermal barrier coating systems, we observed the opposite: γ remained stable at room temperature, yet it underwent a γ →

Carbonate‐ Versus Hydroxide‐Based Precursor for the Synthesis of Li/Mn Rich Cathodes: Exploring Differences in Discharge Capacities and Cycle Life

open access: yesSmall Science, Volume 6, Issue 8, August 2026.
The synthesis of Li/Mn‐rich cathodes via hydroxide‐based precursor can be beneficial in terms of, for example, lower surface area. The apparently disadvantageous lower lithiation amount (discharge capacity) is shown to be beneficial for cycle life, as the higher redox oxidation number in the discharged state suggests a lower amount of detrimental Mn3+.

Dislocation Bands and Subboundaries in Experimentally Deformed Olivine

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Transmission electron microscopy imaging of dislocations in olivine indicates heterogeneous structures and diversity of dislocation types. However, the volumes imaged at high resolution are smaller than individual grains even of fine‐grained samples.

A Physics‐Based Frequency‐Temperature Seismic Anelastic Attenuation Model for Planetary Ice Shells

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Intrinsic attenuation in planetary ices remains poorly constrained at seismic frequencies and low temperatures, limiting quantitative predictions of wave propagation in icy moons. Existing models typically rely on constant‐Q, or power‐law formulations that lack microphysical grounding and fail to capture the strong temperature sensitivity of ...

Prevalence of Peri‐Implantitis Around Zirconia Implants: A Systematic Review and Meta‐Analysis of Current Evidence

open access: yesClinical Implant Dentistry and Related Research, Volume 28, Issue 4, August 2026.
ABSTRACT Background Zirconia implants (ZIs) have emerged as a metal‐free alternative to titanium implants (TIs) because of their favorable esthetic and biological properties. However, the prevalence of peri‐implantitis associated with ZIs and the potential influence of implant material on peri‐implant disease remain unclear.
