The bar was undoubtedly set high: In the research project Functional Oxides Printed on Polymers and Paper – FOXIP for short – the goal was to succeed in printing thin-film transistors on paper substrates or PET films. Electronic circuits with such elements play an important role in the growing Internet of Things (IoT), for example as sensors on documents, bottles, packaging … – a global market worth billions.

Researchers from the University of Rostock and Technion Haifa have created the first three-dimensional topological insulator for light. A judiciously placed screw dislocation allows optical signals to wind around the surface of a synthetic lattice while keeping it protected from scattering.
Their discovery has recently been published in the journal Nature (« Photonic topological insulator induced by a dislocation in three dimensions »).

In a newly-published study (Small, « A Universal Pick-and-Place Assembly for Nanowires »), a team of researchers in Oxford University’s Department of Materials led by Harish Bhaskaran, Professor of Applied Nanomaterials, describe a breakthrough approach to pick up single nanowires from the growth substrate and place them on virtually any platform with sub-micron accuracy.

While efficiency is a primary concern for solar cells, researchers have also focused on developing solar cells that are lightweight, low-cost, and flexible. However, the fabrication process itself has posed a serious environmental concern: the use of toxic materials and generation of industrial waste.

The rapid development of ultra-thin electronic skins (e-skins) – also called epidermal electronics or electronic tattoos – is opening new realms of possibility for flexible and stretchable monitoring gadgets that are wearable directly on the skin. These e-skin devices can be used for, among other things, prosthetics and rehabilitation, optogenetics, human-machine interfaces, human-computer interaction in gaming, and as diagnostic tools in the medical field (read more on this topic in « Lab-on-skin: Nanotechnology electronics for wearable health monitoring »).

If you don’t see an icon, check Control Center by swiping down from the top-right corner. As of now, there are no built-in customization options for the appearance of the White Arrow on iPhone. This feature ensures that when you open an app, the latest information is readily available. How to Pair Meta Quest 3 […]

There’s nothing like the smell of freshly brewed coffee in the morning. But how does one measure that smell? There’s no energy in a smell to help estimate how potent the coffee might be …

Supplements should never be taken as a replacement for a prescribed blood-thinning medication. Your doctor will test you with an international normalized ratio (INR) test. If you take an anticoagulant like warfarin, you’ll need regular blood tests so your doctor can adjust your levels if needed. Ask them about other steps you should take to stay […]
