Abstract Interfacial modular assemblies of eco‐friendly metal–phenolic networks (MPNs) are interest for surface and materials engineering. To date, most MPNs assembled on water‐stable substrates; however, the self‐assembly highly water‐soluble substrates remains unexplored. Herein, a versatile approach is reported to engineer thickness‐tunable coatings (2–25 µm) substrate (i.e., urea) via in no...
Van Slyke and Folch (1) used as a combustion mixture a solution of H&04, HsP04, and CrOa, to which pulverized KI03 was added in the combustion tube. It has been found advantageous instead to use as a fluid a mixture of H&S04 and HsPOa without CrOs, both KI03 and KzCrzOr being added in solid form in the combustion tube. This modification has the advantage that both the liquid and the solid reage...
there are two major theories of measurement in psychometrics: classical test theory (ctt) and item-response theory (irt). despite its widespread and long use, ctt has a number of shortcomings, which make it problematic to be used for practical and theoretical purposes. irt tries to solve these shortcomings, and provide better and more dependable answers. one of the applications of irt is the as...
abstract lexical knowledge of complex english words is an important part of language skills and crucial for fluent language use (nation, 2001). the present study, thus, was an attempt to assess the role of morphological decomposition awareness as a vocabulary learning strategy on learners’ productive and receptive recall and recognition of complex english words. so 90 sophomores (female and ma...
Limitations of achieving highly sensitive and stable surface-enhanced Raman scattering (SERS) substrate greatly concern the suitable method for fabrication of large-area plasmonic nanostructures. Herein we report a simple approach using template-based synthesis to create a highly ordered two-dimensional array of gold-silver alloy nanowires, followed by the controlled dealloying process. This pa...
A new strategy to reduce the operating temperature of solid oxide fuel cell (SOFC) is needed foster progress developing high-performance and stable SOFC as a solution thermal stress degradation components induced by high-temperature SOFC. The use lithium (Li) cathode can increase cell’s efficiency, it allows for faster ion transport higher reaction rate. This study presents an attractive approa...
Glycerol dry reforming (GDR) was studied on Ru/La2O3, Ru/ZrO2, and Ru/La2O3–ZrO2 catalysts. Impacts of the support morphological, electronic surface chemical properties catalysts were comprehensively characterized by TEM, in–situ DRIFTS, XPS, ATR–IR XRD. Initial (5 h) CO2 conversion at 750 °C CO2–to–glycerol ratio 1–4 ordered as Ru/La2O3 < Ru/ZrO2 Ru/La2O3–ZrO2. During 72 h stability tests, dea...
