The nucleus of an atom contains protons and neutrons. However, some atoms of the same chemical element can have varying numbers of neutrons, giving so-called isotopes of that element. Most elements have both stable and radioactive isotopes. Radioactive isotopes of an element are commonly used as tracers in medical, biological, and industrial studies to gain information about physical and mechanical processes. In geology and archaeology, radioactive isotopes are used to determine the age of a sample while hydrologists can use isotope signatures to distinguish between different groundwater types.
In the health sector, isotopes are used for the diagnosis of heart disease, locomotive disorders and cancer, for therapy and palliative applications. Every year more than 30 million medical treatments and over 100 million laboratory tests are carried out using isotopes. In the environmental field, isotopes are used for the measurement of air and water pollution, and to understand effects and risks to public health and environment from certain management scenarios for radioactive waste. In the field of industrial safety, radioisotopes are used to detect flaws in steel sections used for bridge and jet airliner construction, and to check the welds on pipes, tanks and other structures. In consumer protection and safety, isotopes are used to study the quality of foodstuffs and their metabolisation by humans.

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...
