In cooperation with development partner Engel Holding GmbH (Schwertberg, Austria) automation specialist Fill (Gurten, Austria) has developed a consolidation system for the production of high-quality composite components. Layers of continuous fiber-reinforced, recyclable plastic tapes are fused (consolidated) under temperature and high pressure to form a homogeneous semi-finished product. Even high-temperature plastics (up to 450°C), such as those used in aviation, Fill says, can be processed reliably, flexibly and in constant quality with this system.

In a potential boost for quantum computing and communication, a European research collaboration reported a new method of controlling and manipulating single photons without generating heat. The solution makes it possible to integrate optical switches and single-photon detectors in a single chip.

Nature Communications, the team reported to have developed an optical switch that is reconfigured with microscopic mechanical movement rather than heat, making the switch compatible with heat-sensitive single-photon detectors.
Optical switches in use today work by locally heating light guides inside a semiconductor chip. This approach does not work for quantum optics, says co-author Samuel Gyger, a PhD student at KTH Royal Institute of Technology in Stockholm.
