Building lightly in an efficient manner
Together with three companies the Institute for Aircraft Construction (IFB) at the University of Stuttgart researched the automated conversion of components for aeronautical applications with a high lightweight potential, such as for example structures of aircraft seats or reinforcements of window frames.
The efficiency of the automation process as well as the quality and functionality of the products resulting from this is to be increased through a number of further developments. The objective of the project going by the name of “3D TFP“ is the material-efficient manufacturing of the products as well as a sustainable reduction in CO2 emissions in flight operations.
In order to achieve this, the partners use a manufacturing process with which the expensive carbon fibres can be arranged almost without offcuts and with a good load-bearing capacity in the component (Tailored Fibre Placement, in brief TFP process). Since an effective and to date quick deposit of the fibres has only been possible on the flat side, a reliable method to convert these semi-finished products is to be developed into a complex 3D structure.
The focus thereby is an automated and resource-efficient production of aeronautical components that on the one hand reduces the process tolerances and on the other hand the overall process costs. With this the door to production would be opened in a high-wage country like Germany. Furthermore, the scientists wish to integrate additional functions such as, for example conductive or sensory elements in the component. These added values are to justify the higher manufacturing costs compared to the classic metal construction and increase the market opportunities of the end product.
Alongside the IFB at the University of Stuttgart as the main developer, the consortium comprises the manufacturer of aircraft seats RECARO Aircraft Seating in Schwäbisch Hall, the synthetic resin manufacturer Sika Deutschland in Bad Urach and the process automation supplier Siemens from Stuttgart. Within three years the partners jointly intend to press ahead with the automated manufacturing of low cut-off waste semi-finished products to manufacture lightweight parts from fibre plastic composites. The project is being funded with a sum of 321,000.- Euros by the State of Baden-Württemberg in the framework of the strategy for the lightweight construction.

Using an ultra fast-scanning atomic force microscope, a team of researchers from the University of Basel has filmed “living” nuclear pore complexes at work for the first time. Nuclear pores are molecular machines that control the traffic entering or exiting the cell nucleus. In their article published in Nature Nanotechnology, the researchers explain how the passage of unwanted molecules is prevented by rapidly moving molecular “tentacles” inside the pore.

If a person pushes a broken-down car alone, there is a certain effect. If another person helps, the result is the sum of their efforts. If two micro-particles are pushing another microparticle, however, the resulting effect may not necessarily be the sum their efforts. A recent study published in Nature Communications, measured this odd effect that scientists call “many body.”
