Silicone sponge captures unknown bacteria


Microorganisms populate nearly any habitat, no matter how hostile it is. Their great variety of survival strategies is of huge potential in biotechnology. Most of these organisms, however, are unknown, because they cannot be cultivated. To make better use of this "microbial dark matter", the KIT) has now developed a "sponge" made of porous, formable silicone.

ProQuIV optimizes the production of nonwoven masks


Producing infection control clothing requires a lot of energy and uses lots of material resources. Fraunhofer researchers have now developed a technology which helps to save materials and energy when producing nonwovens. A digital twin controls key manufacturing process parameters on the basis of mathematical modeling.

The VR glove from the 3D printer


In a project called "Manufhaptics", researchers at Empa, together with EPFL and ETH Zurich, want to develop a VR glove that will make virtual worlds tangible. The VR glove is to be created using a 3D printing process and will have three different actuators.

Powered-up plastics


A research team from the Fraunhofer Institute for Manufacturing Engineering and Automation IPA has succeeded inadditively manufacture sensors and other electronic devices in a single operation. As part of this research, the conductivity of thermoplastic elastomers (TPE) was tested to find out, for example, how best to incorporate electronic components.

Plastics of the future will live many past lives, thanks to chemical recycling


A research team at the University of Colorado Boulder has discovered how durable plastics used in the aerospace and microelectronics industries broken down into their most basic building blocks and then formed again into the same material. In the process, they do not lose their physical properties.

Researchers develop plastic film that can kill viruses using room lights


Researchers at Queen's University Belfast have developed a plastic film that uses room light to kill viruses that land on its surface. The technology used to manufacture the film also ensures that it is degradable. This self-sterilizing film is inexpensive to produce, easy to scale and could be used for disposable aprons, tablecloths and curtains in hospitals.

Recycled PET bottles are turned into adhesive tapes


The company tesa® supports the field of sustainability. The new tesa® 60412 packaging tape has a backing made of 70% recycled PET and a water-based acrylate adhesive system. The production process is completely solvent-free. Used PET products are recycled and used as raw material for the backing material.

Shining light on why plastics turn yellow


A research team has investigated whether intended nanostructures formed by UV light could be the cause of yellowing of polyethylene. The result was that chiral chemical structures form on the surfaces of polyethylene films during exposure to UV light and are a possible cause of the yellow color of old plastics. These findings could help researchers develop plastic products that last longer.
