Deterministic Fiber‐Optic Spectral Engineering Enables Three‐Color Multiplexed Two‐Photon Microscopy

Laser &Photonics Reviews, EarlyView.
A simulation‐guided spectral‐engineering framework maps the nonlinear parameter space of a fiber laser platform to identify balanced three‐band excitation states. The resulting 960, 1080, and 1175 nm femtosecond pulses deliver nJ‐level energies for low‐cross‐talk chromatically multiplexed two‐photon microscopy.

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.

Failure Investigation of Alloy 625 Sockolets After Prolonged Service in an Ammonia Cracker Unit

Materials and Corrosion, EarlyView.
The failure of the sockolets was caused by intergranular cracking and fracture. The thick and highly brittle nitrided layer formed intergranular surface cracks, which propagated along grain boundaries into the base alloy substrate due to the presence of brittle Cr‐rich carbides. ABSTRACT Several sockolets of Alloy 625 operating at 540°C in contact with

Effect of Re or W Addition on the Oxidation Behaviour of a Compositionally Complex Ta–Mo–Cr–Ti–Al Alloy in Air at 1000°C

Materials and Corrosion, EarlyView.
The effect of addition of 3 at.% of either Re or W on the oxidation performance of equimolar Ta–Mo–Cr–Ti–Al is investigated and found to be beneficial, at least temporarily. Additionally, the oxide (Ti,Ta)O2 has been identified and characterised as a main part of the oxide scale. ABSTRACT Presuming that doping of protective (Cr,Ta,Ti)O2 with cations of

Existence Analysis of a Three‐Species Memristor Drift‐Diffusion System Coupled to Electric Networks

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT The existence of global weak solutions to a partial‐differential‐algebraic system is proved. The system consists of the drift‐diffusion equations for the electron, hole, and oxide vacancy densities in a memristor device, the Poisson equation for the electric potential, and the differential‐algebraic equations for an electric network.
