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 …

The anthocyanin composition of five purple leaves cultivars of Ocimum basilicum L. was investigated by reversed-phase HPLC with mass-spectrometric detection by ESI mode with ion partial fragmentation as well as preparation of dried differently colored forms of anthocyanins encapsulated into maltodextrin …

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 …

Karapet’yants comparative analysis is applied to anthocyanin retention using the example of an extract of Adonis aestivalis petals. The attribution of anthocyanin peaks according to the comparative analysis is confirmed by the parameters of the mass spectra. A set of purple maize anthocyanins is used …

Voor het meten van elektrochemische processen van micro- tot nanoschaal wordt een techniek ontwikkeld die elektrochemische impedantiemetingen met een AFM naald mogelijk maken. Hierbij bevindt zich actief materiaal op een AFM naald en worden er metingen verricht in elektrolyt. Tijdens dit onderzoek …

Using the reversed phase high performance liquid chromatography with diode-array and massspectrometric (in ESI mode) detection, a composition of Catharanthus roseum petals was established. After the acid hydrolysis, all five anthocyanidins were found to be different comparing to the ordinary anthocyanidins …

Een grote overeenkomst in symptomatologie tussen de bipolaire- (BS) en borderline persoonlijkheidsstoornis (BPS) vormt een probleem in zowel de diagnostiek als de behandeling van deze stoornissen. Een betere differentiaaldiagnostiek is dus gewenst. Dit onderzoek richt zich op de emotieregulatie, wat …

With sufficient electrical energy CO2 from the atmosphere, combined with water, can be converted to hydrocarbons. The first step in converting CO2 into a carbon based fuel is the dissociation of CO2 into CO and O. DIFFER explores the possibilities of this process by using a microwave plasma. This project …

Patients suffering from bacterial bloodstream infections have an increased risk of developing systematic inflammatory response syndrome (SIRS), which can result in rapid deterioration of the patients’ health. Diagnostic methods for bacterial identification and antimicrobial susceptibility tests are time-consuming. …

Cyanobacteriochromen (CBCR) zijn fytochroom-gerelateerde fotoreceptor eiwitten, die van eiwitstructuur veranderen wanneer deze belicht worden met bepaalde kleuren licht. Tijdens deze foto-conversie transformeren de CBCRs van de ene stabiele staat naar de andere, via het doorlopen van verschillende tussenproducten. …
