Spotless surfaces are of prime importance in the plastics and metal processing industries, as dust and dirt can impair the function and adhesive properties of parts. A portable measuring device, the KombiSens, can detect both types of contamination.
Greasy fingerprints on wineglasses, ketchup on the table, crumbs on the floor – anyone with a clean disposition would be disgusted. But spotless surfaces are not the prerogative of housework maniacs; they are essential in numerous sectors of industry such as car manufacturing or metal processing, where dirt can have an adverse affect on gluing and painting processes or impair a component’s function.
When manufacturers are planning to coat a surface, they carry out regular spot checks to determine how clean their parts are. Many of these analysis methods fail to reveal defective cleaning until some time has elapsed – and meanwhile production has continued with the faulty workpieces. Researchers at the Fraunhofer Institute for Manufacturing Engineering and Automation IPA in Stuttgart have developed an easy-to-use test device for checking cleanness during the production process. KombiSens detects both dust and grease on surfaces.

Porous crystalline materials: TU Graz researcher shows method for controlled growth

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
