Microplastics is spreading more and more, especially in the sea. The impact of microplastics on animals and humans has not been researched in the long term. In the next years, the Chair of Fluid Mechanics and Turbomachinery at the TU Bergakademie Freiberg wants to develop together with scientists of the Johannes-Gutenberg-University Mainz and the TU Munich as well as three industrial partners an innovative atomization process for the production of new bio-based and biodegradable microparticles.
In the next years, the Chair of Fluid Mechanics and Turbomachinery at the TU Bergakademie Freiberg wants to develop together with scientists of the Johannes-Gutenberg-University Mainz and the TU Munich as well as three industrial partners an innovative atomization process for bio-based, biodegradable polymer materials.
These environmentally friendly microparticles shall replace environmentally harmful microplastics in shampoos and other cosmetics.
The Bioshampoo project examines the complete process chain from conception of the process, particle development, integration into a final product (shampoo), and final biodegradability testing after initiation into the water cycle.
"Microplastics" consists of plastic particles with a size of a few nanometers to a few millimeters. Petroleum-based microplastics is currently contained in many cosmetic products. In sewage treatment plants, these very small particles are difficult to break down or filter off.
In the new atomization process, the feed material obtained from natural substances is first melted and then the melt is forced through a nozzle via a high speed gas flow.
The melt decays into individual droplets, which form predominantly spherical particles after solidification. These are supposed to perform the same function as microplastics in cosmetics, but the participating scientists expect that the nature-based microparticles can be removed much easier and faster from the wastewater.
The project is funded under the Central Innovation Program for Small and Medium-sized Enterprises (ZIM) with a total of approxemately 1.1 million Euros. In the project application and implementation, the scientists were and are supported by the innoscripta GmbH Munich.

Microelectronics as a key technology enables numerous innovations in the field of intelligent medical technology. The Fraunhofer Institute for Biomedical Engineering IBMT coordinates the BMBF cooperative project "I-call" realizing the first electronic system for ultrasound-based, safe and interference-resistant data transmission between implants in the human body.
When microelectronic systems are used for medical applications, they have to meet high requirements in terms of biocompatibility, reliability, energy...
Thomas Heine, Professor of Theoretical Chemistry at TU Dresden, together with his team, first predicted a topological 2D polymer in 2019. Only one year later, an international team led by Italian researchers was able to synthesize these materials and experimentally prove their topological properties. For the renowned journal Nature Materials, this was the occasion to invite Thomas Heine to a News and Views article, which was published this week. Under the title "Making 2D Topological Polymers a reality" Prof. Heine describes how his theory became a reality.
Ultrathin materials are extremely interesting as building blocks for next generation nano electronic devices, as it is much easier to make circuits and other...
Scientists took a leukocyte as the blueprint and developed a microrobot that has the size, shape and moving capabilities of a white blood cell. Simulating a blood vessel in a laboratory setting, they succeeded in magnetically navigating the ball-shaped microroller through this dynamic and dense environment. The drug-delivery vehicle withstood the simulated blood flow, pushing the developments in targeted drug delivery a step further: inside the body, there is no better access route to all tissues and organs than the circulatory system. A robot that could actually travel through this finely woven web would revolutionize the minimally-invasive treatment of illnesses.
A team of scientists from the Max Planck Institute for Intelligent Systems (MPI-IS) in Stuttgart invented a tiny microrobot that resembles a white blood cell...
By studying the chemical elements on Mars today -- including carbon and oxygen -- scientists can work backwards to piece together the history of a planet that once had the conditions necessary to support life.
Weaving this story, element by element, from roughly 140 million miles (225 million kilometers) away is a painstaking process. But scientists aren't the type...
Study co-led by Berkeley Lab reveals how wavelike plasmons could power up a new class of sensing and photochemical technologies at the nanoscale
Wavelike, collective oscillations of electrons known as "plasmons" are very important for determining the optical and electronic properties of metals.
