Applying electron beams to 3-D objects

23.09.2016

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP now has the technological means of applying electron beams very flexible to 3-D objects through use of its new electron wand of the Swiss company ebeam by COMET.

Electron beams are useful in many different applications. They reliably sterilize seed, can weld small structures precisely and reliable, and cure decorative paint. Usually this involves either planar, flexible, or slightly curved surfaces. However, applying electron beams homogeneously to 3-D objects of any size or shape has not been so simple up to now.

Scientists at Fraunhofer FEP have now elegantly combined an electron wand with a six-axis robotic manipulator in order to be able to treat substrates with complex shapes as well as spherical objects, for example.

“The electron wand remains stationary in this process”, explains Javier Portillo, a scientist at Fraunhofer FEP. “The manipulator rotates the objects within the irradiation zone in a way, that the surface will be treated homogeneously. This creates the maximum degree of freedom when applying an electron beam to a 3-D-object.”

Normally you need several electron-beam sources to treat 3-D objects. Homogeneous application does not take place reliably everywhere in this process. The process of multiaxial moving the object within the electron treatment zone can hereby generate advantages. The application of electron beams to optical components is also conceivable.

These primarily involve hydrophilic surfaces found in a wide variety of applications, such as safety glasses with antifogging coatings, diffusing screens and lenses, and anti-condensation coatings for air conditioners and sensors in medical engineering.

Scientists can apply the new technology to develop customized processes for its industrial clients that meet specific demands – including being able to treat 3-D objects with various geometries – to suit even the most diverse existing production lines.

The symbiosis of an electron beam and robotic handling can make production processes more effective and economical.

Among other places, the new technology will be presented by Javier Portillo at the 12th Ionizing Radiation and Polymeric (IRAP) symposium taking place on the Giens Peninsula in France from September 25 – 30, 2016.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
