Rational design of Ni‐based catalysts for methane dry reforming: Recent advances and future perspectives

FlexMat, EarlyView.
Addressing the challenges inherent in dry reforming of methane (DRM), this paper focuses on the structural design and performance optimization of Ni‐based catalysts. The modulation strategies for DRM are systematically reviewed across four dimensions: the micromorphology of active metals, metal‐support interactions, electronic modifications by ...

Optimizing Na and Rb Incorporation Along With Bandgap Grading for High Efficiency Ultra‐Thin CIGSe Solar Cells

Progress in Photovoltaics: Research and Applications, EarlyView.
In this work, Na and Rb are incorporated into ultra‐thin Cu(In,Ga)Se2 (< 500 nm). By systematically varying the Rb content and combining predeposited Na with postdeposited Rb, we identify the optimal configuration, achieving solar cell efficiencies of 11.72% on Mo and 10.48% on ITO. Through electrical and compositional measurements, a mechanistic model

Near‐Atomic Investigation on the Elemental Redistribution During Coprecipitation of Nano‐Sized Kappa‐Type and B2 Precipitates in an Al‐Alloyed Lightweight Steel

steel research international, EarlyView.
Elemental redistribution during coprecipitation of kappa (κ)‐type and B2 precipitates in an Al‐alloyed lightweight steel is revealed by atom probe tomography (APT) and density functional theory (DFT). Fe and Ni redistribution promotes the evolution of B2 phase from NiAl‐type toward FeAl‐type and improves the stability of κ and B2 phases during ...

KINETICS OF COMBUSTION IN THE LAYERED Ni-Al SYSTEM

Combustion Science and Technology, 2001
Theoretical analysis and experimental results on the combustion in the Ni-Al layered system are presented. Combustion wave temperature and velocity were measured and microstructural and compositional determinations were made. The latter were made on products of complete combustion and on quenched samples using metallographic and electron microprobe ...
