"Production and consumption of poly(bisphenol-A carbonate) resins are seeing a worldwide increase. However, their usage lifetimes are short and their final disposition as landfills pose environmental and health risks, du...

Background: Microbial lipid production represents a potential alternative feedstock for the biofuel and oleochemical industries. Since Escherichia coli exhibits many genetic, technical, and biotechnological advantages ov...

"The fissility is the ability of some rocks to split along relatively smooth surfaces parallel to the bedding. This property observed mostly in fine-grained rocks is particularly expressed in outcrops, where rocks are su...

"The thermochemical decomposition of beech wood biomass results in a poor quality bio-oil, which cannot be directly used in diesel engines. In order to make this oil resemble liquid fossil fuels, an upgrading technique s...

Summary for policymakers Technical summary 1. The climate system - an overview 2. Observed climate variability and change 3. The carbon cycle and atmospheric CO2 4. Atmospheric chemistry and greenhouse gases 5. Aerosols,...

In order to increase the flexibility of renewable energies and improve their integration into existing energy grids, efficient intermediate storage is necessary. High-purity hydrogen produced in a water electrolysis cell...

"This thesis evaluates the technical, economic and environmental performance of a hydrogen fueled hybrid bus, which uses an internal combustion engine as a power unit. Results are compared to those of a conventional dies...
