Both consumer and industrial electronics have become increasingly complex and advanced in recent years. High performance semiconductor devices are essential to the function of these electronics, which is why rapid growth of the microelectronics industry and major technological advancements in this field …

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 …

Amphibians, and in particular anurans, are amongst the most endangered species on earth. Comparing the physiology between urban and rural anurans provides key information on the effect of urbanization on anurans. In turn, this information can help with preservation and conservation of the species as …

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 …

In de afgelopen jaren is er steeds vaker gezocht naar nieuwe methodes om het klimaat van het verleden te kunnen reconstrueren. Voor temperatuur bepalen wordt er onderzocht of Mg isotoop ratio’s hier een indicator voor kunnen zijn. Het verschil tussen twee isotoop ratio’s wordt uitgedrukt in de delta …

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 …

Alzheimer’s disease is the leading cause of dementia affecting over 46 million worldwide, yet contemporary medication is unable to prevent or slow its neurodegeneration. Recently, fucosterol and saringosterol, two phytosterols from brown macroalgae, have emerged as possible mediators of the disease. …

Aminozuren vormen de bouwstenen voor eiwitten en het is algemeen bekend dat deze een belangrijke functie hebben in vele biologische functies. Er is daarom veel belang bij de mogelijkheid om aminozuren snel en efficiënt te kunnen analyseren. De meeste amino zuren hebben een chiraal centrum en daardoor …

The customers of Inspectorate ship gasoline to Asia. Due to the limitations of the ships and costs of the journey it is preferred to concentrate the gasoline. The concentrated gasoline can be blended with other “cheaper” forms of gasoline to make the required gasoline. Because of the concentrated form …

Result of the study on the exposure of imidacloprid on Lymnaea stagnails, have led to this study. The results indicate that imidacloprid might be metabolized to other components. Therefore the aim of the study was two folded: 1. To develop a method for the quantification of imidacloprid and its metabolites. …
