Although the action of the metals in the two forms appeared non-specific, zinc and nickel were found to be more active oxidation catalysts in the heterogeneous form. Furthermore, the metals were found to cause significant reductions in sludge deposit formation in the oils by interfering with the...
Atoms from the metal back electrode such as composed of Au or other metals could diffuse across the HTL into the perovskite layer in PSCs at elevated temperatures under working conditions (Fig. 3d)43. The diffused metal atoms caused irreversible loss of VOC, FF, and JSC of the aged devices...
When a comparison of the analysis to a conventional one-band effective-mass model is made, significant deviations between the two approaches are found to result.关键词:Animals Rabbits Fibroblasts Ethanol Alkanes Water Metals Resins, Plant Chromatography, Gas Biocompatible Materials ...
for many of the metals involved, the basic metabolic pathways are not currently well defined, even without the complication of the endogeneous source represented by the implant. I have found it most curious and interesting that the vast majority of studies ofmetal metabolism, while paying considerab...
16 Acoustic activity was found in the voltage ranges of 1.0–2.5 V (2nd and 3rd cycles) and 1.3–2.5 V (4th and 5th cycles). The shift to higher voltages with increasing cycle number is also evident from the contour plot in Fig. 1c. It depicts the hit density as a function of ...
While most reduced heavy metals in grains, none of the technologies alone were found to be sufficient in field practice to meet national food standards. The current best practice is recognized as the combination of several agronomic measures, including pollution-safe cultivars, optimal water ...
In vivo, composites may either be exposed intermittently or continuously to chemical agents found in saliva, food, and beverages. Intermittent exposure occurs during eating or drinking until teeth are cleaned. Continuous exposure may, however, occur as chemical agents can be absorbed by adherent ...
Currently, element doping and recombination with metals in semiconductors producing nanocomposites (NCs) are commonly used to improve the photoresponse range of ZnO NPs as a photocatalyst. Kareem et al. [23] demonstrated the synthesis of silver-doped ZnO nanoparticles and their enhanced photocatalytic ...
