Unexpected properties for phosphate glass with fly ash
Glass is transparent and strong, but the melting temperature is high and the material is brittle. PhD research by Clarissa Justino de Lima shows that it is possible to improve its properties. She developed a type of glass from phosphate and fly ash with a low melting temperature and an unusual strength.
Acoustic control of your environment
Imagine this: you can control the acoustics of your environment, no matter the size and shape of the space around you, your access to electricity, and the type of sound you’d like to control. That is what the ADAM prototype offers. The parametric design and additive manufacturing process of ADAM allows the creation of tailormade tuned PDI absorbers.
My façade is your façade!?
Recognise this? You need the aircon on in the summer and the heating is on full during the winter, but it never feels really comfortable. It’s definitely not sustainable. By today’s standards, buildings dating from before 1980 tend to guzzle energy, feel uncomfortable and are expensive to maintain. A modern, advanced façade gets rid of some problems, but under what circumstances is this kind of renovation a realistic option?
Information technology does not (yet) provide many proximity benefits
At a time when half the world is working at home because of a pandemic, it hardly seems imaginable. Nevertheless, teleworking as a strategy to take advantage of the proximity of a large city turns out to be less successful than expected. "If employees can work at home for one or more days, they are prepared to accept greater commuting distances," says De Vos. It is one of the most important effects he discovered in his PhD research.
A mine of information in waste data
It is not uncommon for tools to be developed for research projects, but the tool to emerge from REPAiR (REsource Management in Peri-urban Areas) is one to be particularly proud of. And this is not only in the eyes of TU Delft researchers Alexander Wandl and Arjan van Timmeren. “Local and regional authorities in both Europe and the United States can't wait to start using it.”
