Advanced composite aileron for L-1011 transport aircraft: Ground tests and flight evaluation [PDF]

A composite aileron and a metal aileron were subjected to a series of comparative stiffness and vibration tests. These tests showed that the stiffness and vibration characteristics of the composite aileron are similar to the metal aileron.

Unravelling Electronic Structure and Molecular Vibrations of Proteins in Virus Using Novel Correlated Plasmon‐Enhanced Raman Spectroscopy With Machine Learning

Small, EarlyView.
A novel, non‐destructive, stable, direct technique, named correlated plasmon‐enhanced Raman spectroscopy (CP‐ERS), which is based on a newly‐developed highly oriented single crystalline gold quantum dots (HOSG‐QDs) chip, is developed to measure and quantify molecular vibrations and electronic structure of analytes.

Intrinsically Chiral Excimers: Water‐Compatible Trityl‐Based Nanoparticles as Tailored Dual Emitters of Circularly Polarized Luminescence in the Vis or NIR Regions

Small, EarlyView.
Dual circularly polarized luminescence (CPL) is demonstrated in pioneering metal‐free organic nanoparticles (ONPs) from a brominated trityl radical derivative. CPL activity in the Vis or NIR regions in aqueous environments is achieved by tayloring the content of radical enantiomers in ONPs, thanks to the generation of intrinsically chiral excimers ...

Effects of structural coupling on mistuned cascade flutter and response [PDF]

The effects of structural coupling on mistuned cascade flutter and response are analytically investigated using an extended typical section model. This model includes both structural and aerodynamic coupling between the blades. The model assumes that the

Conformational bifurcation drives dual transport regimes in molecular junctions: Unsupervised machine learning insights

Smart Molecules, EarlyView.
Conformational bifurcation in n‐alk‐1‐yne molecular junctions drives dual transport regimes, with unsupervised machine learning and XPS revealing distinct planar and skewed conformers influencing conductance and tunneling efficiency. This discovery highlights anchor‐group control as a key design principle for tailoring molecular electronic devices ...

Multifaceted Behavior and Functional Versatility of Ferritic Stainless Steels, Part I: Applications and Processing, a Review

steel research international, EarlyView.
This review investigates the processing‐microstructure‐property relationships in ferritic stainless steels (FSSs). It highlights advances in deformation behavior, heat treatments, surface modifications, and alloying effects. Theoretical models, including Johnson‐Mehl‐Avrami‐Kolmogorov, Arrhenius, nucleation theory, and diffusion theories, are discussed
