چکیده
Reasonable design of a kind non-noble metal catalyst with high catalytic performance, good stability and low cost is great significance to realize the overall water splitting. Herein, bottom-up method proposed synthesize NiFe layered double hydroxides (NiFe LDHs) coated sulfide/phosphide heterostructure on nickel foam (Ni3S2-NixPy/NF@NiFe LDH) through hydrothermal combined electrodeposition. Low overpotentials only 248 298 mV are required achieve current densities 50 100 mA cm−2 for OER. Meanwhile, HER performance needs 137 at density 10 cm−2.

construction of vector fields with positive lyapunov exponents
in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...

like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولBoosting the Efficiency of Suspended Photocatalysts for Overall Water Splitting.
Water Splitting I is a significant task to cover the residential energy demand of a society (approximately 20% of the total) with solar energy, but it is a much greater challenge to cover all of it, including the demands of industry, commerce, and transportation. The 20% goal may be achievable through photovoltaic-powered households and appliances, but the 100% goal will require extensive facil...
