Optimizing Detection Schemes for Broadband Pump‐Probe Microscopy

Microscopy Research and Technique, EarlyView.
Small spot sizes and broadband spectral coverage create unusual noise challenges for broadband pump‐probe microscopy. Analysis of probe and detector noise characteristics can provide strategies for mitigating these challenges. ABSTRACT Although similar to more commonly implemented single wavelength approaches, broadband pump‐probe or transient ...

Temperature‐Dependent Investigation of the S‐Branch Raman Linewidth in CO2 via Time‐Resolved Rotational CARS

Journal of Raman Spectroscopy, EarlyView.
We studied the temporal evolution of the rotational coherent anti‐Stokes Raman scattering (RCARS) signal of CO2 to determine the S‐branch Raman linewidth, which is an essential parameter for accurate spectral modeling in RCARS gas‐phase diagnostics. We found a non‐monotonic J‐dependence of the S‐branch Raman linewidth not accounted for in previously ...

Effects of yttrium on microstructure and mechanical properties of Mg-6Al magnesium alloy [PDF]

China Foundry, 2010
Since Y has a great solid solubility in magnesium alloys, it helps enhancing the heat-resistant property of magnesium alloys. The effects of Y on microstructures and mechanical properties of Mg-6Al alloy have been studied in this work.

Alloy Solutions for Ammonia Cracking: A Review

Materials and Corrosion, EarlyView.
This work provides a literature overview of the nitriding and degradation of structural materials under ammonia cracking conditions and explains the known mechanisms and the gaps, where research is required. ABSTRACT Hydrogen is a key factor in energy storage and transportation, which will inevitably lead to a substantial increase in demand.

Quantification of Alkali‐Fluoride Nanoparticle Dissolution in Aqueous Media as a Function of Crystallinity and Surface Modification

Particle &Particle Systems Characterization, EarlyView.
Fluoride release kinetics from uncoated and coated β−NaYF4$\ubeta-{\rm NaYF}_4$ and LiYF4${\rm LiYF}_4$ in aqueous solutions are quantified using an ion‐selective electrode coupled to a dialysis compartment. TEM/DLS/ICP‐OES and speciation‐aware modeling complement the fluoride release results.

Thin Fluoride Insulators for Improved 2D Transistors: From Deposition Methods to Recent Applications

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
2D materials hold significant promise for next‐generation electronic and optoelectronic devices, but suitable gate dielectrics are still a challenge. Fluoride insulators, offering inert, dangling‐bond‐free surfaces, have recently emerged as strong candidates. This review covers recent publications on high‐quality fluoride thin‐film deposition and their

Parametric Excitation of a Ferrimagnetic Sphere Resonator

Advanced Quantum Technologies, EarlyView.
The hypothesis that disentanglement spontaneously occurs in quantum systems is experimentally tested using a ferromagnetic resonator. Predictions derived from the hypothesis, and from an alternative theoretical model, are compared with the measured response of the resonator to an externally applied driving.

Improved Corrosion Resistance of Yttrium-Bearing H13 Steel for Shield Machine Cutter Ring

Metals
H13 steel, which was used as the material for shield machine cutter rings, required tempering to attain superior mechanical properties. The Cr-rich carbide that precipitated during the tempering process definitely decreased the corrosion resistance of ...
