We report on a high convergence ratio liquid layer capsule implosion performed the National Ignition Facility and contrast it to two previously reported layered implosions, in order better understand how design impacts hydrodynamic stability properties of implosions. Three implosions were with similar ratios, fuel entropy, in-flight aspect unablated shell mass; these qualities are important for determining stability. Nevertheless, while exhibited robustness asymmetries, including our recent...

The Pd/Ga ratio influences the phases formed during catalysis. best catalyst necessitates formation of Pd–Ga intermetallic compounds and also a low content Ga<sub>2</sub>O<sub>3</sub>, whose excess tend to block surface sites.

Recent studies have focused on the promotion of methanol synthesis by CeO2 and inhibition reverse water gas shift reaction (r-WGSR) TiO2 support from perspective nature active sites morphology. Nevertheless, rational design catalysts needs to account additionally for mechanism, a topic that has not yet been addressed CuCeOx/TiO2. Herein, CO formation pathways over this catalytic system were unraveled. Kinetic, isotopic, spectroscopic techniques combined obtain mechanistic insights both...

Perovskite-type compounds (La1–xAgx)Mn0.9Co0.1O3 (x = 0.0, 0.1, 0.2, 0.3), prepared by the amorphous citrate method, have been investigated as catalysts for soot combustion. The were characterized nitrogen adsorption, XRD, SEM, TPR, O2-TPD, and XPS techniques. silver addition to perovskites produces a slight modification of specific surface area crystalline structure, while new source oxygen that comes from interaction between O– low-coordinated metal site was detected. results suggest that,...
