We report characterization of spray-based nanoporous particle synthesis for use in the cathode of lithiumion batteries. Ultrasonic Microarray Spray Tuning (uMIST) was used to create microdroplets of salt solutions and battery material precursors, and the size distributions of produced microdroplets were investigated with a MicroOrifice Uniform Deposit Impactor (MOUDI). Experimental challenges a...

The accurate estimation of deposits adhering on insulators is of great significance to prevent pollution flashovers which cause huge costs worldwide. Researchers have developed sensors using different technologies to monitor insulator contamination on a fine time scale. However, there is lack of analysis of these data to reveal spatial and temporal characteristics of insulator contamination, an...

Microcalcification is a tiny abnormal deposit of calcium salt especially in the breast cancer that in the human female is often an indicator of breast cancer. In currently the microcalcification cluster is a important primary sign of breast cancer. The breast cancer is detected the early stage and it is identify the benign or malignant. The existing approaches is tend to concentrate on to the m...

An aqueous hybrid inorganic/organic sol-gel solution composed of tetraethylorthosilicate (TEOS), methyltriethoxysilane (MTES) and (3-glycidyloxypropyl)trimethoxysilane (GPTMS) was applied on ZnFe (14 wt.% Fe) electrodeposited steel as a sacrificial layer. Two precursor contents were studied: 10 (SG10) 30 % (SG30). First, the morphology thickness films assessed by Scanning Electron Microscopy (S...

Gas turbine materials often feature precipitates containing refractory metals to enhance their mechanical strength. This can make them susceptible alloy-induced acidic fluxing whereby elements increase the acidity of salt deposits. It is not clear what degree degradation around alloy caused by hot corrosion mechanisms, or inability develop a protective scale where are located. The effect was is...
