This last point is what we would call pollution and it is easy to detect now thanks to the advances by the doctoral thesis recently presented in the Department of Edaphology and Agricultural Chemistry of the University of Granada (Universidad de Granada [http://www.ugr.es]).
The study "Propuesta de criterios para determinar los valores de niveles característicos de metales pesados en suelos y sedimentos a partir de métodos entrópicos" (A criteria proposal to determine the values of characteristic levels of heavy metals in soils and sediments from entropic methods), prepared by Rafael Bellver Mancheño, under the supervision of teachers Juan Antonio Fernández García and Mariano Valderrama Bonnet, goes deeply into the knowledge of soil genesis in Eastern Andalusia, in an area of 350 square kilometres.
Most of the times, heavy metals can be naturally found in soils and sediments, but the study detects a series of points where it would be advisable to reduce or remove certain heavy metals which are gradually increasing. According to Bellver Mancheño, this topic can generate an excessive social alarm due to the association, sometimes mistaken, between the presence of heavy metals and pollution.
With the method suggested by the UGR [http://www.ugr.es], it is possible to observe the development of the concentration of the different metal elements studied. To this extent, new methods for data analysis have been designed to discuss the results of chemical analysis and compare them to other previously obtained in the same field of study.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
