Sample preparation

In this work, SrFe12O19 samples were synthesized by hydrothermal method. We systematically studied the influence of an alkaline environment (NaOH) with the molar ratio (R) of 2 , 3 and 4 on the structure, magnetic properties of SrFe12O19 particles prepared by hydrothermal method. The relation between morphology, magnetic properties and microwave absorption properties of materials have been investigated.

This study is to determine impacts of the dynamics of digital transformation as a strategic choice of banks on their performance under constant changes of technology, notably financial technologies and relatively stable market conditions such as macroeconomic policies, legal framework and industry structure. A sample of 23 Listed Commercial Banks in Vietnam was used that is based on the availability of ICT readiness index as a measure for the banks’ initial stages to prepare for digital transformation journey.

The 3D printing PMMA/ZrO2 filaments with a diameter of 1.75±0.05 mm were fabricated by using a single-screw extruder at temperatures of four heating zones of 190, 200, 210, and 210°C. Testing samples were prepared from the extruded filaments by using a fusion deposition modeling 3D printer and a Haake MiniJet piston injection molding machine. Fourier transform infrared spectroscopy, mechanical properties, field emission scanning electron microscopy (FESEM), differential scanning calorimetry, and thermogravimetric analysis of the filaments were investigated.

Ebook "Analytical chemistry applied to emerging pollutants" addresses the highly relevant subject of emerging pollutants, which are especially alarming since most of the available treatment technologies are unable to degrade them. It discusses the sources of these pollutants and their fate in the environment, and the main tools available for their analysis. It also describes the representative environmental matrices (air, soil and water) and appropriate analytical methods for each matrix.

To reduce consumed chemicals and time, we developed a simple and rapid sample preparation procedure for PAH analysis in settled dust samples. The dust samples were extracted by using two ultrasonication techniques such as direct extraction (ultrasonic processor) and indirect extraction (ultrasonic water bath). Some extract clean-up techniques were also investigated. The proposed method was applied to analyze a representative settled road dust sample with and without native standard spiking.
