On 29-30th September 2021 Elantas, a German producer of materials for electronics, hosted a virtual web-seminar on the printed electronics industry. A wide range of predominantly German companies and organizations presented, outlining their current portfolio of products and services for printed electronics.

Most modern concrete usually only lasts decades whereas some of today's alternatives last longer. Concrete degradation of our infrastructure now requires high repair costs, which can be avoided if we use self-healing concrete in the first place. However there are cost and other issues with this relatively new technology.

With global warming kicking in and rising sea levels displacing millions to arid regions, there needs to be much more cooling of buildings. Two new passive options need to be welcomed that use readily available, non-toxic substances - metamaterials and unprecedentedly white paint reflecting maximum sunlight away from a building.

A research team has set a new efficiency record for a perovskite solar cell at 25.8% by forming an interlayer between electron-transporting and perovskite layers to minimize interfacial defects, contributing to the decrease in the power conversion efficiencies.

Sure, you could attach two screens with a hinge and call a cell phone "foldable," but what if you could roll it up and put it in your wallet? Or stretch it around your wrist to wear it as a watch? The next step in digital displays being developed could make that a reality.

How can doctors make sure a dressed wound is healing without taking off the bandage? This is a conundrum, because removing a bandage can disrupt the healing process. Technology presented in a new study in open-access journal Frontiers in Physics could help.

Optomec has introduced a new high performance semiconductor packaging solution for the rapidly growing mm-wave electronics market, in response to demands from its customers in the 5G, Autonomous Vehicle, Defense and Medical segments.
