The technological centre Robotiker from Zamudio (Basque Country) has developed a system of artificial sight to separate metals that come with copper, in order to obtain high purity copper.
Its in this machine where they recover copper from old cables
To recover copper from old cables it is not something new. However, the recycled copper is not pure, because it is mixed with other metals, such as lead, aluminium and tin. It is quite complicated to separate copper from those components by using mechanical, physical and other methods. Nevertheless it is easy to distinguish impurities through the eyesight.
The recycling of cables has been promoted by the need to change conventional telephone lines. The price of the material obtained from the recycling of electrical and telephone cables depends on the level of purity of the copper. Therefore, the fact of having lead, aluminium and tin along with copper determines the use and, hence, the price of copper.

Spectrally narrow x-ray pulses may be “sharpened” by purely mechanical means. This sounds surprisingly, but a team of theoretical and experimental physicists developed and realized such a method. It is based on fast motions, precisely synchronized with the pulses, of a target interacting with the x-ray light. Thereby, photons are redistributed within the x-ray pulse to the desired spectral region.
A team of theoretical physicists from the MPI for Nuclear Physics (MPIK) in Heidelberg has developed a novel method to intensify the spectrally broad x-ray...
Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
