Perfluoro alkyl substances (PFAS) are substances in which contain multiple fluorine atoms. The fluorine atoms are bound to, often, long carbon chains. PFAS are able to repel dirt and water, due to the large amount of fluorine atoms in the molecules. PFAS are also chemically and thermally stable. Many …

Early links in the food web are crucial to sustain higher levels in the food web. Molecules of high importance, for example unsaturated fatty acids, play a key role in aquatic ecosystems. Unsaturated fatty acids are produced by primary producers for instance phytoplankton. Almost all organisms need to …

A main challenge in single emitter microscopy is that it is difficult to efficiently collect all the emitted light from single photon sources. Due to the dipole nature of the single photon sources, is it hard to measure the brightness of these molecules in a calibrated manner, since the light is not …

Tires are an important vehicle component, as car handling, safety and fuel economy depend for a major part on the tire composition and construction. As a consequence, tires are improved continuously. The most prominent improvement in the recent past was the use of a silica-silane filler system in passenger …

UPLC-MS is a commonly used technique to first separate complex samples and subsequently quantify molecules of interest. Herein we describe the use of UPLC-MS using an amide stationary phase to quantify non-derivatized amino acids extracted from fingerprints. As detector either a triple-quadrupole MS/MS …

Potato, came from south America long time ago, the tuber is grow about everywhere in the world to become the fourth worldwide crop. Its worst enemy is an oomycete, the Phytophtora infestans. This disease is responsible for millions of deaths and forced migration in Ireland during the Great Famine from …

At the 41th IAEE International Conference Martien Visser was part of a Round Table Session. He presented his insights about the use of green molecules, why they should be used and which green molecules can be used.

Abstract from the article: "Conjugates of fatty acids and amines, including endocannabinoids, are known to play important roles as endogenous signaling molecules. Among these, the ethanolamine conjugate of the n-3 poly unsaturated long chain fatty acid (PUFA) docosahexaenoic acid (22:6n-3) (DHA) was …

Accumulating evidence dismisses the idea that bacteria are solitary bugs, living a completely independent existence. Instead, this definition is being replaced by the notion that bacteria are intimately communicating organisms holding tight relations to one another. One such process through which this …

Gas-phase diffusion is a widespread process in nature, for example diffusion of pollutants in the atmosphere. A special case of diffusion is the so-called Knudsen diffusion where a gas diffuses in the molecular flow regime. The theory for Knudsen diffusion is well-known therefore, diffusion experiments …
