We propose a simple ink formulation and rapid preparation technique to deposit 20 mol% gadolinium-doped ceria electrolyte utilizing nanopowders polymeric dispersant. The was assessed for printability successfully printed using piezoelectric inkjet materials printer. ejected drops were investigated built-in stroboscopic imaging during ejection, the deposited thin films characterised optical micr...
Crude oil spills from tankers remain a serious threat along coastal California. Resource managers require information on the acute toxicity of treated and untreated oil, and their sublethal effects on wildlife. This investigation compared the toxic actions of the water-accommodated fraction (WAF) and the chemically-enhanced WAF (CEWAF; Corexit 9500) of Prudhoe Bay crude oil in pre-smolt Chinook...
The oil spill dispersant (OSD) play an important role to deal with the frequent oil spills in the marine environment, which can effectively reduce the interfacial tension between the oil and the seawater. However, there are many studies showing the stability of the OSD effect changes over time, and is related with the wave. In this paper, the results show the OSD will gradually move away from t...
We demonstrate a generic approach for the synthesis of single-crystal complex oxide nanostructures of various structure types, such as perovskites, spinels, monoclinic, corundum, CaF(2) structured, tetragonal, and even metal hydroxides. The method is based on a reaction between a metallic salt and a metallic oxide in a solution of composite-hydroxide eutectic at approximately 200 degrees C and ...
Cu-Ag particles with homogeneous cover-silver layer were synthesized by electroless plating of copper particles with silver sulfate using eco-friendly sodium citrate (SC) as reducing agent, dispersant and chelating agent in an aqueous system. The influences of sodium citrate/Cu and sodium citrate/Ag ratios on Ag coatings of Cu powders were investigated. Ag formed a dense coating on the surface ...
