Ultralow‐Backscattering Induced Mode Splitting in Chipscale Valley Photonic Topological Cavities

Laser &Photonics Reviews, Volume 20, Issue 12, 18 June 2026.
The proposed in‐situ metrology based on mode splitting quantifies the ultralow backscattering of topological valley edge states at a single sharp corner, demonstrating near‐lossless topological transport (0.09 dB/corner) on a silicon chip. This work provides insight into the robustness of the photonic valley system and shows the great potential of ...

Prediction of the Diffusion Behavior of Interstitial Nonmetallic B and N Atoms Diffusing in FCC_CoNiV Multi‐Principal Element Alloy Based on Sublattice Preference: A Comparative Study

Materials Genome Engineering Advances, Volume 4, Issue 2, June 2026.
This work investigates the diffusion behavior of interstitial B and N atoms diffusing between the neighbor octahedrons in FCC_CoNiV MPEA based on sublattice preference model and compared with the C diffusing behaviors' data in our previous published work.

Excitonic Theory of the Ultrafast Optical Response of 2D‐Quantum‐Confined Semiconductors at Elevated Densities

Advanced Quantum Technologies, Volume 9, Issue 6, June 2026.
In this work, an excitonic many‐body theory for the ultrafast optical response at elevated excitation densities for Wannier–Mott excitons is developed and applied to two distinct materials (GaAs quantum well and MoSe2 monolayer) as proponents of two different Coulomb‐interaction regimes.

Oxygen Doping and Crystal–Amorphous Multiphase Coupling Synergistically Improve the Wear Resistance of NiTiCu Alloy

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT NiTi shape memory alloys (SMAs) show excellent performance in vibration damping and corrosion resistance. However, due to low hardness and lack of self‐lubrication, they suffer severe friction and wear during service. Although various strategies including doping and heterostructure design have been proposed, the effects are unsatisfactory.

Single Cu Atom Sites on Co3O4 Activate Interfacial Oxygen for Enhanced Reactivity and Selective Gas Sensing at Low Temperature

Small, Volume 22, Issue 32, 8 June 2026.
Atomically dispersed Cu sites on Co3O4 nanoparticles establish well‐defined Cu–O–Co interfacial linkages that promote lattice oxygen activation at markedly reduced temperatures. This structural and electronic modulation yields over twenty‐fold higher low‐temperature formaldehyde sensing responses than CuO nanoparticle analogues, enabling selective and ...

Selective Solar CO2 Conversion into Ethanol Using Atomic‐Scale Copper Clusters Anchored π‐extended Poly(heptazine imide)

Small, Volume 22, Issue 32, 8 June 2026.
Atomic‐scale copper clusters anchored on π‐extended poly(heptazine imide) enable selective, sacrificial‐agent‐free solar conversion of carbon dioxide (CO2) to ethanol. The catalyst promotes interfacial charge separation and stabilizes key carbon‐carbon coupling intermediates, providing a molecularly defined platform for direct C2 fuel synthesis under ...
