As the researchers report in the journal
Advanced Functional Materials, the material has a variety of applications in the energy, medical, and fashion sectors.
Living materials, which are made by housing biological cells within a nonliving matrix, have gained popularity in recent years as scientists recognize that the most robust materials are often those that mimic nature.
“Three-dimensional printing has shown to be an effective technology for fabricating living materials that have many environmental and other benefits,” says Anne S. Meyer, an associate professor of biology at the University of Rochester.
“Our photosynthetic living materials are a huge step forward for the field since they are the first example of an engineered photosynthetic material that is physically robust enough to be deployed for real-world applications,” Meyer says.

Hi everyone,
This is a transcript of my presentation over at the European Microwave Week
2020, actually held in 2021. You can find the video
here and the slides
here. I’d like to thank Frank van
Vliet,
general chair of the EMW, for inviting me to do this talk.
The words have only been edited lightly - it is still presentation style, so
here and there the sentences are not written like how they’d be in a more
formal piece of work.

Welcome everyone, to this perhaps somewhat strange presentation. I’ve
As part of Fieldlab, 5000 fans attended a 27 March soccer match between the Netherlands and Latvia.

The Eurovision Song Contest, known best for its over-the-top performances and outrageous costumes, has a new feature this year: It will be the site of a massive field experiment to see whether concerts and other events can be held safely in the middle of the COVID-19 pandemic. Nine rehearsals and televised shows, staged 18–22 May in Rotterdam, Netherlands, will each be attended by 3500 visitors who will have to show a recent negative SARS-CoV-2 test to get in. Those admitted can choose to drop social distancing and go without face masks precautions currently mandatory in indoor public spaces in the Netherlands, where most people remain unvaccinated.

A wearable wristband containing a thermoelectric generator (TEG) can convert body heat into enough electricity to power an LED. In future, the technology may be able to power smartwatches and end the need for traditional charging hardware.
“Energy supply is always a big issue, and this could help alleviate the energy crisis,” says Qian Zhang of the Harbin Institute of Technology, China, one of the co-authors of the paper, who has worked on TEGs for more than 15 years.
TEGs are used in a wide range of applications, but are often rigid – something Zhang and her colleagues sought to solve. They layered a magnesium and bismuth material – the TEG materials – between polyurethane and a flexible electrode, enabling the wristband to wrap around a human arm.

The use of composite materials has become a new norm in the aerospace and mobility sectors. While the weight, strength and usability benefits are clear, there are still some big gaps to fill – namely a knowledge gap in knowing how to inspect, repair and extend the life cycle of such material. To fill this void, NLR is teaming up with material and technology experts to launch the DCMC, aimed at enhancing knowledge and technology to keep the composites world moving.
If you’ve driven a car over the last few decades, you’ve probably noticed a change in construction. While bodies remain largely steel, more and more of the structural parts come from composite materials like carbon fiber. Similarly, the aerospace sector has also adopted the use of composites, as it cuts down on weight and subsequently, fuel. And with all eyes on fighting climate change, wider use of these durable and lightweight composite materials is certain to be a big piece of the puzzle in lowering emis
