Organic acids are used in several industrial sectors, such as food or pharmaceutical industry and serve as building block chemicals for a vast variety of products. Up to date many of them are obtained from petrochemical resources, implementing energy intensive chemical refining and waste production with a high environmental impact [1]. The enormous annual demand requests the development of efficient and sustainable bioprocesses for organic ...

The results of studies investigating the impact of automated vehicles can vary substantially, partly due to different assumptions on key input parameters such as costs and travel behavior. We therefore present a detailed cost analysis that was performed for 17 metropolitan areas in 15 different countries. Furthermore, we show the results of a comprehensive survey that was conducted in the canton of Zurich of Switzerland, with the intent ...

Naturally occurring methane has two sources, defined as biogenic methane and thermogenic methane. Biogenic methane is the product of microbial activity, the formation of thermogenic methane is controlled by temperature, pressure and also by the composition of organic matter preserved in the sediments. Gas hydrates form the largest methane sink in the methane cycle. Methane hydrate is a mix of water molecules forming an ice structure and ...
