Industrial accidents provoked by the lack of oxygen could be prevented thanks to a device designed by the UGR

06.10.2006
Oxygen, an essential element for life, accounts for 21% of the air we breathe.

However, certain works are carried out in conditions where levels can be lower with fatal consequences for persons. There fore it is, according to the scientists, a safety system, fruit of a collaboration agreement between the University of Granada and the Spanish Command for Training and Army Doctrine (MADOC), whose headquarter is in this city.

In order to improve the features and solve some of the disadvantages of the existing equipments, the scientists have carried out an instrument for oxygen measurement, as big as a mobile phone, easy to use and with a minimum maintenance costs. This way, it is possible to get to know the local concentration of such gas in every moment. This device is essential in those places where manufacturing, cleaning and maintenance works, such as ships, septic tanks, sewer systems, can be harmful for human health.

The definite prototype, patented by the UGR [http://www.ugr.es], is made up of a screen, where you can visualize data, and three buttons: screen lighting, another one to access the menu bar and the third one for measurement.

The system works automatically, and can be programmed to carry out measurements every minute or in ten-minute intervals. At the same time, the user can carry out measurements at any moment, without interfering in the previous proceeding. Anyway, the user will notice that the measurement has been done through a sound alarm. Equally, such signal will activate automatically if oxygen concentration in the environment is lower than 18%.

One of the advantages of this device against conventional ones is the auto-calibration option. According to the researchers, you just have to place the device outdoors in the ‘auto-calibration’ mode of the menu, to recalibrate the system in thirty seconds. On the other hand, according to scientists, as it is an optical instrument it does not receive electromagnetic interferences, and it is apt to be placed in industrial environments.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
