AIRS, the Atmospheric Infrared Sounder instrument on Aqua, provides scientists with infrared satellite imagery. That imagery measures cloud top temperatures and sea surface temperatures. If the cloud tops in low pressure areas or tropical cyclones are colder than -63 degrees Fahrenheit, it indicates strong thunderstorms and strong convection (rapidly rising air that condenses and forms the thunderstorms that power tropical cyclones).

On May 27 at 1:35 a.m. EDT (05:35 UTC) AIRS imagery showed System 90E developing the trademark tropical cyclone approximately 205 nautical miles south of Salina Cruz, Mexico near 12.8 North and 94.5 West. AIRS infrared imagery indicated there were four areas of strong thunderstorms with very high, cold cloud tops around the center of circulation. Infrared satellite imagery indicates a slowly consolidating, broad low-level circulation center.
Winds in the area are estimated to be 20 to 25 knots (23-28 mph). System 90E is trudging west at 1 mph. The Joint Typhoon Warning Center noted that System 90E "is expected to continue consolidating over the next 24-36 hours. The potential for the development of a significant tropical cyclone within the next 24 hours is good."

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.
