Most world governments are concerned with waste disposal. The large accumulation of these waste items is causing environmental and monetary issues. According to (Awuchi, 2019), the predicted average daily production of plastic waste is 15.4 billion pieces. Plastic waste is the most prevalent form of …

The upscaling of biphasic photochemical reactions is challenging because of the inherent constraints of liquid-gas mixing and light penetration. Using semi-permeable coaxial flow chemistry within a modular photoreactor, the photooxidation of the platform chemical furfural was scaled up to produce routinely …

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 methodology of biomimicry design thinking is based on and builds upon the overarching patterns that all life abides by. “Cultivating cooperative relationships” within an ecosystem is one such pattern we as humans can learn from to nurture our own mutualistic and symbiotic relationships. While form …

Most FLP research focuses on intrafamily communication (1FLP) and how this is impacted by larger contexts. But what happens when different multilingual families interact intensively on a daily basis? This article analyses language use during a holiday in India in and between four deaf-hearing befriended …

Part of the project: TFF-Optimization of Mixing Elements. Polymer mixing with a single screw extruder is a common process in industry. Mixing quality depends on (amongst others) the screw geometry. The main objective of this study was to quantify distributive mixing behavior of a single screw extruder …

Small urban water bodies, like ponds or canals, are often assumed to cool their surroundings during hot periods, when water bodies remain cooler than air during daytime. However, during the night they may be warmer. Sufficient fetch is required for thermal effects to reach a height of 1–2 m, relevant …
