Herein, Zeolitic imidazolate framework-8 (ZIF-8) is considered as an easy and cheap to prepare alternative catalyst for the isomerization of glucose and production of 5-hydroxymethyl furfural (HMF). For the synthesis of the ZIF-8 catalysts two preparation methods were evaluated, being room temperature …

Consumers who buy organic food, have expectations about its quality and rely on certifying organizations to verify this quality and to provide information about the origin of organic products. However, organic food traceability knows several issues, such as problems with organic labelling, certification …

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 …

The Andean lupin (Lupinus mutabilis) is one of the lost crops of Incas and has been grown in South America and as a food crop for thousands of years. The seeds are the main source of commercial value regarding the high content of oil (about 20%), protein (about 43%) and carbohydrates (about 33%). A European …

Om de potentie van katalysatoren ingebouwde in een redox actieve Metal–Organic framework (MOFs) volledig te benutten moet de charge transport / elektron hopping worden geoptimaliseerd. Voor het optimaal functioneren van een katalysator zal de drijfkracht achter het mechanisme van elektron hopping moeten …

The 'AgroCycle' project investigates whether a cooperation of farms can become self-sufficient in energy and fertilization by using manure and organic waste streams for the production of energy, green fuel and green fertilizers by means of anaerobic digestion (AD). In the project, the project partners …

Saybolt is a petrochemical company that invest in different types of oils and fuels. Saybolt Vlaardingen has purchased a new Perkin Elmer Optima 8300 ICP-OES (Inductively coupled plasma optical-emission spectrometry) that must be validated. The ICP-OES is used to analyze metals in petroleum products. This …

Many attempts have been made to build an artificial brain. This paper aims to contribute to the conceptualization of an artificial learning system that functionally resembles an organic brain in a number of important neuropsychological aspects. Probably the techniques (algorithms) required are already …

Past decades traditional agricultural landscapes characterized by a wide variety of grasslands, field boundaries, watercourses, and trees started to disappear. Population growth required an ever-increasing demand for food and traditional agricultural systems were converted to monocultures. With this …

Natural Deep Eutectic Solvents (NADES) represent a green chemistry alternative to utilization of common hazardous organic solvents. They were introduced by Abbott et al. [1], and were found to have a wide range of compositions and favorable properties. NADES are typically obtained by mixing hydrogen-bond …
