Focusing Polarization‐Splitting Grating Coupler in Lithium Niobate on Insulator Photonic Platform

Advanced Photonics Research, Volume 7, Issue 10, October 2026.
Compact, focusing polarization‐selective grating coupler with low (<1 dB) polarization‐dependent loss (PDL), operating at the telecom C‐band and fabricated at a standard LNOI foundry using a process design kit (PDK). Lithium niobate‐on‐insulator (LNOI) is a rapidly emerging platform for integrated photonics, offering high‐speed modulation, efficient ...

Laser Surface Treatment of Nickel‐Alumina Coating for Enhancement of Erosion and Corrosion Resistance of High Speed Steel Vanes

Applied Research, Volume 5, Issue 5, October 2026.
Laser surface treatment was carried out to enhance the performance of Ni‐Al2O3 coatings on HSS substrates. The results revealed improved microstructural features, corrosion resistance and significant reduction in slurry erosion wear with 18 W laser treatment. ABSTRACT The sliding wear between hydraulic vane tip and the inner surface of the cam ring can

Burning Lessons: The Failure to Learn From Major Fire Incidents

Fire and Materials, Volume 50, Issue 6, Page 702-704, October 2026.
ABSTRACT Major fire disasters continue to cause substantial loss of life, economic damage, and social disruption worldwide. Although investigations occur in most countries, lessons learned are often fragmented, published in incompatible formats, or not published at all.

Tailoring Radial Dopant Homogeneity in Silica‐Based Laser Active Media Using Variable SiO2 Precursors in Atmospheric Pressure Plasma‐Based Nanoparticle Synthesis

Particle &Particle Systems Characterization, Volume 43, Issue 10, October 2026.
The study compares two silica precursors, TEOS and OMCTS, for producing Yb2O3, Al2O3‐doped nanoparticle aggregates via atmospheric microwave plasma. TEOS‐based sol–gel precursors yield 20‐40 times higher dopant homogeneity in vitrified samples than OMCTS‐based emulsions. This difference is attributed to distinct evaporation behaviors and water content,

In‐Situ Construction of Multi‐Scale Heterogeneous Structures in L‐DED IN718 Coatings via WMoTaNb Incorporation for Enhanced Strength‐Toughness Synergy

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT To improve the strength–toughness balance of IN718, and alleviate the brittleness commonly associated with refractory high‐entropy alloys, this study proposes a novel strategy to fabricate defect‐free IN718/WMoTaNb heterogeneous multiprincipal element alloy coatings via laser‐directed energy deposition.
