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 …

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 …

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, …

The catalytic conversion of oleic acid to aromatics (benzene, toluene, and xylenes, BTX) over a granular H-ZSM-5/Al2O3 catalyst (ϕ 1.2–1.8 mm, 10 g loading) was investigated in a continuous bench-scale fixed-bed reactor (10 g oleic acid h–1). A peak carbon yield of aromatics of 27.4% was obtained at …

WHY? (ADAPT) The city of Liège is suffocating because of extreme car hospitality. Public space has been stripped down to traffic space, serving the singular purpose of moving and parking polluting, dangerous and space inefficient cars. Global challenges concerning pandemics, climate change and sub-urbanization …

A topic of great social relevance in the current century is implementing innovative sustainable production processes. Globally waste management is one of the biggest sustainability challenges. With urbanization and a growing global population, the use of various products and discarding their waste has …

The European Union is implementing policies to achieve its priorities of the European Green Deal; A Europe fit for the digital age; An economy that works for people; and A stronger Europe in the world. To achieve these goals, there is a need for a paradigm shift in the way public and private sector organisations, …

Purpose This paper explores the potential andpitfalls of Lesson Study (LS) in Dutch initial teacher education (ITE). This context is examined through data drawn from student-teachers and teacher educators participating in LS. Design/methodology/approach Three case studies of three teacher education …
