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 …

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 …

In this research, acrylate crosslinked PEG-b-PS polymersomes were synthesized and extensively tested. Polymersomes are nanovesicles that are self-assembled from amphiphilic block copolymers. Like liposomes, they can contain aqueous solutions in the core, which makes them interesting in the field of nanomedicine. …

Smart glasses were perceived to be potentially revolutionary for healthcare, however, there is only limited research on the acceptance and social implications of smart glasses in healthcare. This study aims to get a better insight into the theoretical foundations and the purpose was to identify themes …

The synthesis of aromatic compounds from biomass-derived furans is a key strategy in the pursuit of a sustainable economy. Within this field, a Diels–Alder/aromatization cascade reaction with chitin-based furans is emerging as a powerful tool for the synthesis of nitrogen-containing aromatics. In this …

Psychologist and computerscientist Geoffrey Hinton, called the godfather of AI, argued that we should stop with A(G)I. In this column it is argued that Artificial General Intelligence like ChatGPT works very differently than organic intelligence. An organic complexity works like a chain reaction. Unlike …

Injuries are a huge setback for tennis players. Injury prevention needs a detailed understanding of tennis injury epidemiology. Lower extremity injuries occur about equal to or more often than upper extremity injuries in tennis. Although studies have described the incidence rate of injuries across the …

Adding microalgae into food could strongly influence the flavor of the final product which is the key factor for consumer acceptation. To assist food processors in the development of tasteful food products containing microalgae, it is necessary to understand the impact of processing and storage on the …

The objective of this study is to evaluate the energetic, exergetic, sustainability, economic and environmental performances of a 4-cylinder turbodiesel aviation engine (TdAE) used on unmanned aerial vehicles for the take-off operation mode to assess the system with large aspects. Energy efficiency of …

Background In adolescents with non-pathological and pathological joint hypermobility, gait deviations have been associated with pain and fatigue. It remains unclear what distinguishes the non-pathological form of joint hypermobility (JH) from pathological forms (i.e. hypermobile Ehlers-Danlos syndrome …
