Chitin represents an abundant source of nitrogenous polysaccharides, making it a suitable feedstock for organonitrogen platform chemicals. In particular, furanic compounds, such as 3-acetamido-5-acetylfuran (3A5AF), can be readily obtained. Furans can be further functionalized using a Diels–Alder (DA) …

Concrete is arguably the most widely used building material in the world today. Current estimates of world cement manufacture are of the order of 1.7*109 tons per year, enough to produce well over 6 km3 of concrete per year or at least 1 m3 per person (Gartner, 2004). It is a composite material made …

Lignocellulose biorefining is a promising technologyfor the sustainable production of chemicals and biopolymers.Usually, when one component is focused on, the chemical natureand yield of the others are compromised. Thus, one of thebottlenecks in biomass biorefining is harnessing the maximumvalue from …

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 …

An important step towards improving performance while reducing weight and maintenance needs is the integration of composite materials into mechanical and aerospace engineering. This subject explores the many aspects of composite application, from basic material characterization to state-of-the-art advances …

Wynand Alkema vertelt over het gebruik van ChatGPT in het ontwikkelen van nieuwe medicijnen. Een samenvatting van het praatje is hieronder weergegeven:The FAIR use of Large Language Models in the drug development pipeline.With the emergence of applications that are based on large language models (LLMs), …

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 …

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 …

Large floating projects have the potential to overcome the challenge of land scarcity in urban areas and offer opportunities for energy and food production, or even for creating sustainable living environments. However, they influence the physical, chemical, biological and ecological characteristics …
