Article Synopsis
- High-entropy alloys (HEAs), particularly nickel-based ones, are advanced materials known for their exceptional strength, ductility, and corrosion resistance, making them valuable in various applications.
- The review explores the principles of alloy design and the role of nickel, analyzing how composition and structure impact mechanical properties using concepts like valence electron concentration (VEC).
- It also highlights additive manufacturing (AM) techniques, examines their challenges (such as porosity and defects), and evaluates the effects of post-processing methods on the mechanical performance and oxidation behavior of nickel-based HEAs.
Photocarrier Recombination Dynamics in Highly Scattering CuO Nanocatalyst Clusters.
J Phys Chem C Nanomater Interfaces
February 2024
Article Synopsis
- The study focuses on using inversion analysis to measure the dynamics of photoexcited charge carriers in materials like CuO nanoparticles, which are difficult to analyze due to scattering effects.
- Scattering from these nanoparticles leads to significant inaccuracies in measuring the population of excited carriers, reducing their apparent density by an order of magnitude.
- The research also demonstrates that the shape of the nanoparticles affects the photocarrier density response, and it identifies clustering of nanoparticles through scattering analysis, linking these findings back to carrier dynamics.
