Cleaning coal after it has been mined is done with water. The bulk of the coal mined is relatively coarse in size and, therefore, can be readily washed of…
The goal of the 3 years R&D project funded by the European Commission is to reduce the manufacturing costs of tools and to overcome the problem of missing…
The breakthrough technology will provide engineers with much more freedom and creativity by enabling far greater functionality to be incorporated into medical…
Using a cutting edge nanotechnology, researchers at MIT have created a robotic prototype that could autonomously navigate the surface of the ocean to collect…
Ultrafast time-resolved laser spectroscopy is a technique that uses the interaction of light with matter to study the properties of physical systems….
A collaborative team of applied scientists from Harvard University and the University of Leeds have demonstrated a new terahertz (THz) semiconductor laser that…
Now, a team led by physicist Charles Clark at the National Institute of Standards and Technology (NIST) puts some numbers to the problem. In one case, the…
Heat-treatable steels are often used for highly stressed construction elements, since they show a high tensile and endurance strength resulting from the heat…
In collaboration with seven partners, the Laser Zentrum Hannover e.V. (LZH) is developing a hybrid welding process which combines the advantages of laser and…
In conventional GMAW, the electric arc naturally follows the path of least resistance between the electrode and the base material. The arc is difficult to…
At this year’s plastics trade show in Düsseldorf (October 27 to November 3, 2010) the Fraunhofer ILT is presenting the TransTWIST laser-based plastics welding…
Precise knowledge of water losses is essential for operating and planning the maintenance of drinking water networks efficiently. The condition of the pipes…
Five Siemens ultraviolet (UV) disinfection plants came into operation in May in the Echthausen Water Works belonging to Wasserwerke Westfalen GmbH, Germany.They have considerably reduced the amount of chemicals used by the drinking water supplier. This process also eliminates microorganisms which cannot always be adequately controlled by other disinfection processes. These new UV plants are part of Wasserwerke Westfalen's extensive investment project to further improve the quality of its drinking water….
Researchers at Rensselaer Polytechnic Institute have developed a new, ultra-simple method for making layers of gold that measure only billionths of a meter…
Nowadays, plastic materials are the most used raw material in the toy sector, because of its good adaptation to any designs, physic-chemical characteristics,…
The regenerative ability of bones is limited. If they are too badly damaged, e.g. by a tumor or an accident, they have to be replaced by implants. At present…
