Buried Unstrained Germanium Channels: A Lattice‐Matched Platform for Quantum Technology

Advanced Science, Volume 13, Issue 40, 17 July 2026.
ABSTRACT Strained germanium (ε$\varepsilon$‐Ge) and strained silicon (ε$\varepsilon$‐Si) buried quantum wells have enabled advanced spin‐qubit quantum processors. However, in the absence of suitable lattice‐matched substrates, ε$\varepsilon$‐Ge and ε$\varepsilon$‐Si are deposited on defective, metamorphic SiGe buffers, which may impact device ...

Parental Social Environment Has no Effect on Offspring Development in the Dung Beetle: A Test of Adult Sex Ratio Effects

Ecology and Evolution, Volume 16, Issue 7, July 2026.
We investigated whether adult sex ratio (ASR) induces transgenerational plasticity in the dung beetle Onthophagus taurus via germline transmission or behavioral parental investment. Although varying ASR treatments significantly altered parental contest and courtship behaviors, utilizing a novel egg‐transplantation protocol revealed no ASR‐induced ...

Microstructure and Wear Resistance of Fe3Al Coating on GCI Prepared by Direct Energy Deposition (DED)

, 2023
In this study, the potential of Fe3Al coating material as an environmentally friendly alternative to coatings containing critical elements for brake discs was investigated. A buffer layer of Cr-Mo steel (Ferro 55) was applied to enhance coating quality and prevent the formation of hot cracks during solidification.
