Point defects in NiAl and other structural intermetallics have been studied using perturbed angular correlation of gamma rays (PAC), by which signals are detected from antisite atoms and/or lattice vacancies in the first few atomic shells of probe atoms. For samples of quenched NiAl having 50 to 54 at.% Ni, site-fractions of Ni-vacancies (proportional to the vacancy concentration) were found to...

پودر ترکیب بین فلزی nial با استفاده از فرآیند آلیاژسازی مکانیکی مخلوط پودرهای نیکل و آلومینیوم خالص تولید شد. با رویکردهای متفاوت افزودن نانولوله های کربنی (cnt) حین آلیاژسازی مکانیکی، پودرهای کامپوزیت nial-cnt تولید شدند. فرآیند تف جوشی پلاسمایی جرقه ای برای تف جوشی پودرهای کامپوزیتی حاصل از آلیاژسازی مکانیکی مورد استفاده قرار گرفت. نتایج نشان داد که حضور نانولوله های کربنی و زمان افزودن آنها ...
The kinetics of mixed Ni-Al layered double hydroxide (LDH) precipitate formation on a soil clay fraction was monitored using X-ray absorption fine structure (XAFS) spectroscopy. The kinetic behavior was monitored at pH 6.0, 6.8, and 7.5 in order to determine the effect of reaction pH on precipitate formation. XAFS analyses were performed on a Ni-reacted whole soil at pH 7.5 to determine the eff...
Highly ordered transparent self-supporting films of layered double hydroxides (LDHs) with a size of the order of cm2 have been obtained by a simple method; the chemical composition of both the layers and interlayers can be readily tuned, as demonstrated by the preparation of [ZnAl-NO3] LDH, [NiAl-NO3] LDH and [Tb(EDTA)]- intercalated-ZnAl LDH films.
A smart supercapacitor was fabricated by loading a thermosensitive polymer P(NIPAM-co-SPMA) onto the surface of NiAl-layered double hydroxide (LDH) nanowalls grown on a flexible Ni foil substrate, which displays temperature-triggered on-off ion channels for controlling the electrochemical behavior.
Hydrazine decomposition over Irn/Al2O3 model catalysts prepared by size-selected cluster deposition.
Hydrazine decomposition chemistry was probed over a temperature range from 100 to 800 K for a series of model catalysts prepared by mass-selected Ir(n)(+) deposition on planar Al(2)O(3)/NiAl(110). Two sets of experiments are reported. Temperature-programmed desorption (TPD) was used to study hydrazine desorption and decomposition on Al(2)O(3)/NiAl(110) and on a model catalyst prepared by deposi...
