In this study, corrosion behaviour of A356-10 vol.% SiC composites casted by gravity and squeeze casting is evaluated. For this purpose, prepared samples were immersed in HCl solution for 1h at open circuit potential. Tafel polarization and electrochemical impedance spectroscopy (EIS) were carried out to study the corrosion resistance of composites. The Tafel polarization and EIS studies of ...

This study focuses on the semiconductor properties of passive films formed on AISI 420 stainless steel immersed in four nitric acid solutions under open circuit potential (OCP) conditions. For this purpose, the passivation parameters and semiconductor properties of passive films were derived from potentiodynamic polarization and Mott–Schottky analysis, respectively. The OCP plots showed that th...

The aim of the study is to better understand where uranium deposits in mice kidneys. The spatial distribution of uranium was examined in the kidneys of C57BL/6 mice using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). Mice were exposed to varying levels of uranyl nitrate in their drinking water. Calibration standards were developed to allow for semi-quantitative measur...

The performance of an Imidazoline based commercial corrosion inhibitor on CO2 corrosion of mild steel was investigated in a Cl- containing solution employing linear polarization resistance (LPR), potentiodynamic polarization and monitoring corrosion potential techniques. Experimental results showed that an increase of the commercial inhibitor concentration up to 500 ppm increases the RP value a...

Vertical graphene (VG) sheets were single-step synthesized via inductively coupled plasma (ICP)-enhanced chemical vapor deposition (PECVD) using waste lard oil as a sustainable and economical carbon source. Interweaved few-layer VG sheets, H₂, and other hydrocarbon gases were obtained after the decomposition of waste lard oil. The influence of parameters such as temperature, gas proportion, ICP...

• Multi-Element Analysis Introduction Laser ablation inductively coupled plasma-mass spectrometry (LA-ICP-MS) has developed over recent years to become a sophisticated tool for the multielemental and isotope ratio analysis of solid samples. Besides a true multi-elemental capability, independent of matrix, the major requirements for most geological laser applications in ICP-MS are the highest se...

Progress in medical knowledge can be represented by an ascending spiral in which every loop stands over previous data, adds new findings that deepen our understanding of a disease, and helps to design further research and therapeutic strategies. New loops are frequently inspired by novel approaches to accepted hypotheses and usually supported by the use of more advanced technologies, as seems t...

A commercially available direct mercury analyzer (DMA) based on sample combustion, pre-concentration by amalgamation with gold, and atomic absorption spectrophotometry (AAS) was coupled to a sector field inductively coupled plasma mass spectrometer (ICP-MS). The combined system (DMA-ICP-MS) was optimized and evaluated for the determination of mercury in environmental samples using both external...

Analysis of Kemps and Land O’Lakes brand 2% milk was performed to detect aluminum, magnesium and calcium levels. ICP-AES was utilized because of its quick run time and ability to detect all three elements simultaneously. Mg and Ca levels were found to be well below expected values and Al was in too small a concentration to detect using this method. A possibility for the low results was that the...
