TL;DR: The immobilization of Pd on the magnetite surface afforded Nanocat-Fe–Pd using inexpensive precursors and its catalytic role in the Buchwald–Hartwig reaction for arylation of amines and amides was investigated.

TL;DR: In this article, the average size of the crystalline domains of the Au nanoparticles (fcc structure) increased from about 6-nm to 13-nm after annealing at 800-°C, with a progressive crystallization of the CuO matrix in the monoclinic structure.

TL;DR: In this article, the authors show that the onset shift depends on both the coverage of adsorbed species that change the work function and the size of low work function patches, and that manipulating the extraction field intensity enables transition between the measurement regimes.

TL;DR: In this article, local structures and electronic properties of II-VI quaternary Zn0.98Fe0.02Te0.91Se0.09 mixed crystal are studied by X-ray absorption fine structure (XAFS) while the surface composition and its oxidation in air are investigated by Xray photoelectron spectroscopy (XPS).

TL;DR: In this article, an XPS containing XSAM 800 setup, produced by Kratos, was upgraded and the detection system nonlinearity and the transmission function of the upgraded system were measured.
