“This is an exciting early step in developing a sustainable system for producing electricity from hydrogen” said Professor Chris Pickett (Associate Head of the Biological Chemistry Department at JIC). ”In Nature iron–sulphur enzymes catalyse a range of important chemical reactions that industry can only do by using precious metal catalysts and/or high temperatures and pressures. Based on Nature’s blueprint we are a step closer to building an iron-sulfur catalyst for reactions fundamental to a sustainable hydrogen economy”.
As a blueprint for their syntheses the JIC team used the known molecular structures of the catalytic centre - ‘the H-cluster’- found in the iron–only hydrogenase enzyme from two bacteria (Desulfovibrio desulfuricans and Clostridium pasteurianum). Hydrogenases catalyse interconversion of protons, electrons and hydrogen at extraordinary high rates. Their colleagues in Italy and the US  used state-of-the-art computational and spectroscopic techniques to probe the properties of the artificial H-cluster. The synthetic cluster was found to catalyse the reduction of protons to hydrogen albeit with poor energy efficiency. Nevertheless, the researchers believe their discovery should provide a lead to new materials that could eventually replace platinum.
 The John Innes Centre (JIC), Norwich, UK is an independent, world-leading research centre in plant and microbial sciences. The JIC has over 850 staff and students. JIC carries out high quality fundamental, strategic and applied research to understand how plants and microbes work at the molecular, cellular and genetic levels. The JIC also trains scientists and students, collaborates with many other research laboratories and communicates its science to end-users and the general public. The JIC is grant-aided by the Biotechnology and Biological Sciences Research Council.

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.
