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.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
