Per-fluoroalkyl and polyfluoroalkyl substances (PFASs) are persistent organic pollutants and do not degrade in the environment. They contain a carbon-fluorine bond, and these are called organic fluorides. A group of PFASs, which can be extracted from soil samples and be analysed, are called extractable …

SMPD4 is a neutral sphingomyelinase that plays an important role in sphingolipid metabolism. Sphingolipids are a family of lipid molecules abundantly present in the brain where they play an important role in the brain development and function due to their essential cellular role as structural components …

In this research several methods were developed and validated using the Supermini 200 wavelength dispersive X-ray fluorescence spectrometer. A multielement was calibrated containing 26 elements and corrected for interference according to the de Jongh algorithm. The limits of detection and quantification …

This research is to investigate to what extend the NIOSH-7605 and ISO-16740 methods can be used to determine insoluble hexavalent chromium in air. The methods were tested and optimized on the extraction and sample preparation steps. After optimization the methods were validation on limit of detection …

An attempt was made to develop a method for the determination of volatile organic compounds (VOCs) in air by gas chromatography mass spectrometry (GC-MS) analysis and chemical sample desorption of the 3M 3500 passive diffusion sampler. The method included a complex mixture of 205 polar and non-polar …

During this research project the influence of selenium enriched growing environment on the phenolic composition on several Allium species is studied. Besides this, the influence on morphological properties is also monitored. Folin-Ciocalteu method is used to determine the total phenolic content and High …

It can be concluded that the HBM4EU serum sample preparation method is suitable for Effect-Directed Analysis. The method allows a recovery of all bioactive compounds of interest from serum in the EDA products, with little loss of compounds: bioassay spectra and chromatograms. Nevertheless, the HBM4EU …

Wilms tumour suppressor gene (WT1) is essential for normal development of a kidney, it was also discovered as a major controller of mesenchymal-epithelial balance in general development of organs. In this project we use Wt1 and its role in the mesenchymal-epithelial balance to study the mechanism of …

A method for directly analysing the nickel content of organic samples by flame atomic absorption is validated. This method is developed to bypass the conventional preparation step for aqueous atomic absorption, which is microwave digestion. The working range of the method is 0 – 30 ppm. The limits of …

Materials with semiconducting properties are present in every microelectronic device and form the backbone of our information society. Commonly used inorganic semiconductors are poorly modular and their production is expensive and energetically demanding. Moreover, the use of metals and critical raw …
