“An Echo To Revive” reintroduces the idea of sports in the heart of the city of Varna, Bulgaria by making it an approachable and interesting subject within the public domain of the urban fabric. Positioned in a key location in the City centre, this intervention aims to connect three distinct areas which …

A time- and space-resolved deactivation study on the conversion of glycerol to aromatics over H-ZSM-5 was performed. For this purpose, glycerol was vaporized/pyrolyzed in a pyrolysis section followed by a catalytic aromatization step. Benchmark performance showed an induction period of ca. 20 min, followed …

This graduation report describes a research project at the research group metabolomics of the Leiden center of Applied Biosciences (LCAB). The aim of this project was to develop a GC-MS method for the identification of red swamp crayfish pheromones (Procambarus clarkii). Once this method has been developed, …

The catalytic conversion of glycerol to aromatics (GTA, e.g., benzene, toluene, and xylenes, BTX) over a shaped H-ZSM-5/Al2O3 (60/40 wt%) catalyst was investigated in a continuous fixed-bed reactor to study the addition of the Al2O3 binder in the catalyst formulation on catalyst performance. The experiments …

Thinking about care in the organization of an ecology is central to the interdisciplinary research group Care Ecologies; found during a lockdown in the spring of 2021 and hosted by ARIAS Platform for Research Through the Arts and Sciences in Amsterdam. In Towards Becoming an Ecology of Care group members …

Music can touch people deeply, and lead to wellbeing as an all-encompassing word for everything that makes life worth living, or at least can make it liveable. Musicians can play an important role in these processes, not as pseudo-therapists, but from their own artistic identity, with an approach in …

Glycerol is an attractive bio-based platform chemical that can be converted to a variety of bio-based chemicals. We here report a catalytic co-conversion strategy where glycerol in combination with a second (bio-)feed (fatty acids, alcohols, alkanes) is used for the production of bio-based aromatics …

De populatie in onze grote steden diversifieert in hoog tempo. Stedelijk cultureel beleid geeft hieraan steeds vaker erkenning waardoor etniciteit, leeftijd, fysieke of mentale beperking, gender of armoede in theorie geen barrière meer vormen om te participeren. Kunsteducatieve professionals die in stedelijke …

The use of H-ZSM-5 with various binders (Al2O3, SiO2, and kaolinite, 10 wt% on catalyst formulation) for the catalytic conversion of glycerol to bio-based aromatics (GTA) was investigated in a continuous bench-scale unit at a pyrolysis temperature of 450 °C, catalytic upgrading temperature of 500 °C, …

Ammonia is heavily used in agriculture as a fertilizer and in industry as a raw material for the production of various organic nitrogen compounds. Its high hydrogen content and its established infrastructure for both storage and distribution makes ammonia a prominent candidate for storing fluctuating …
