The Fraunhofer Institute for Laser Technology ILT established and hosted the first international conference on laser polishing. From May 6-7, 2014, over 70 local and international scientists and laser technology users from various sectors of the industry met in Aachen, Germany. During five different sessions, 14 speakers from six countries expounded topics related to the laser polishing of glass and metals.
Despite a steady increase in recent years in the number of working groups, publications and projects on the subject, laser polishing is still considered a niche technology.

This prompted Fraunhofer ILT to organize the 1st Conference on Laser Polishing LaP 2014 in Aachen, Germany. Headed by Dr. Edgar Willenborg, their event created an international platform for exchanging scientific findings in the laser polishing field. A total of 14 lectures were held in English, providing over 70 participants from 10 countries with the opportunity to gain a comprehensive picture of latest scientific developments and first industrial applications of laser polishing.
Industrial laser polishing
Dr. Thomas Kiedrowski (Robert Bosch GmbH) introduced a metal polishing application that is already in use today and with which millions of components are laser-polished annually. His presentation centered on an example taken from CVT production.
Two lectures given by Dr. Manyalibo Matthews (Lawrence Livermore National Laboratory) and Dr. Philippe Cormont (CEA CESTA) explained another way in which these new methods are being employed successfully, this being to repair optics for high-power laser systems by means of CO2 laser radiation.

In addition to the lectures, a further highlight for conference participants was a tour of the laboratories at Fraunhofer ILT that let them see the latest laser polishing machines and test set-ups. Among other things, visitors were shown a live demonstration of the adaptive laser polishing machine for the polishing of metal work pieces that was developed as part of the BMBF-funded ALPINE project.
The success of the 1st Conference on Laser Polishing – LaP 2014 reflects the great interest the scientific and industrial communities have in this new manufacturing process. There is clearly a significant demand for a cost-effective, automated finishing process that offers an alternative to conventional abrasive methods. This demand will continue to drive research in this area in the future, so we can expect more exciting developments in the field of laser polishing to be unveiled at the 2nd Conference on Laser Polishing – LaP 2016 from April 26-27, 2016 in Aachen.

Today, plants and microorganisms are heavily used for the production of medicinal products. The production of biopharmaceuticals in plants, also referred to as “Molecular Pharming”, represents a continuously growing field of plant biotechnology. Preferred host organisms include yeast and crop plants, such as maize and potato – plants with high demands. With the help of a special algal strain, the research team of Prof. Ralph Bock at the Max Planck Institute of Molecular Plant Physiology in Potsdam strives to develop a more efficient and resource-saving system for the production of medicines and vaccines. They tested its practicality by synthesizing a component of a potential AIDS vaccine.
The use of plants and microorganisms to produce pharmaceuticals is nothing new. In 1982, bacteria were genetically modified to produce human insulin, a drug...
Atomic clock experts from the Physikalisch-Technische Bundesanstalt (PTB) are the first research group in the world to have built an optical single-ion clock which attains an accuracy which had only been predicted theoretically so far. Their optical ytterbium clock achieved a relative systematic measurement uncertainty of 3 E-18. The results have been published in the current issue of the scientific journal "Physical Review Letters".

The University of Würzburg has two new space projects in the pipeline which are concerned with the observation of planets and autonomous fault correction aboard satellites. The German Federal Ministry of Economic Affairs and Energy funds the projects with around 1.6 million euros.

Physicists from Saarland University and the ESPCI in Paris have shown how liquids on solid surfaces can be made to slide over the surface a bit like a bobsleigh on ice. The key is to apply a coating at the boundary between the liquid and the surface that induces the liquid to slip. This results in an increase in the average flow velocity of the liquid and its throughput. This was demonstrated by studying the behaviour of droplets on surfaces with different coatings as they evolved into the equilibrium state. The results could prove useful in optimizing industrial processes, such as the extrusion of plastics.
The study has been published in the respected academic journal PNAS (Proceedings of the National Academy of Sciences of the United States of America).
