Since a research group at Kiel University (CAU) and the Hamburg University of Technology (TUHH) in Hamburg-Harburg has developed aerographite – one of the most light weight materials in the world – in the year 2012 -, they have continued researching about it. Its complex tetrapodal architecture gives the carbon-based 3D material very unique properties, such as extremely high elasticity and electrical conductivity. Now, for the first time, as part of an international research team, materials scientists from the CAU were able to fold the individual hollow tetrapods, each measuring only a few micrometers in size.After bending, the tetrapods automatically retain its original shape, without suffering any damage. This makes advanced applications conceivable, both in...Powered by WPeMatico

Species Richness – a false friend? Scientists want to improve biodiversity assessments

Abuja, african inspired, BLOGS, BUSINESS, IkaTv, Innovation, Innovation Africa, wazobia companies, Youths
Assessing the state of an ecosystem solely on the basis of short-term changes in the number of different species it contains can lead to false conclusions. This is according to a new analysis by an international team including researchers of the Helmholtz Institute for Functional Marine Biodiversity (HIFMB) at the University of Oldenburg and the German Centre for Integrative Biodiversity Research (iDiv). In order to assess ecosystems in a way that is meaningful for nature conservation, experts should instead analyse the turnover of species within a system. The research, based on a mathematical model and environmental data analysis, is published online in the "Journal of Applied Ecology".A growing number of species are under threat of extinction – in particular due to global environmental c

Visiting researcher at Kassel University solves riddle of Cambrian fossils

Three fossils from the Early Cambrian which have long posed a puzzle to scientists belong to the same primeval creature. This has been shown in studies of new finds from the so-called Chengjiang deposits dating back to more than 500 million years ago. Paleontologist Dr. Qiang Ou, a guest researcher working together with Prof. Dr. Georg Mayer at the University of Kassel, played a significant role in the new discovery. These findings provide new insights regarding the evolution of the diversity of species during the so-called Cambrian explosion.Based on the findings of Ou, Mayer, and additional co-authors of the study, the primeval creature †Xianguangia sinica, which lived approximately 520 million...Powered by WPeMatico

Airborne measurements made as part of the Green Ocean Amazon experiment (GOAmazon) show that the Amazon rainforest emits at least three times more isoprene than scientists had previously thought. The research findings were published in Nature Communications.According to Paulo Artaxo, Full Professor at the University of São Paulo's Physics Institute (IF-USP) in Brazil and a co-author of the study, isoprene is one...Powered by WPeMatico

Project FIND – Consortium Develops the Industrial Internet of Tomorrow

Abuja, african inspired, BLOGS, BUSINESS, IkaTv, Innovation, Innovation Africa, wazobia companies, Youths
The rapid digitalization of production and automation is crucial to the successful implementation of the visionary concepts of Industrie 4.0. Among other things, this entails a secure and efficient communication infrastructure that automatically adapts to the requirements of each application; an infrastructure that enables the efficient networking of the production machines, products, and innovative data services; and, one that easily and safely supports the introduction of new industrial applications. Also, the increasing use of wireless technologies and the steady progress in the convergence of IT (Information Technology) and OT (Operational Technology) present special challenges.The FIND consortium is composed of leading proponents from industry and research who have joined together to ...
