Microscale Distribution of Environmental Proxies in Snow
(2019)During a snowfall, chemical compounds from the atmosphere are deposited on the ground. If the snow does not melt completely, as is the case on polar and alpine glaciers, these impurities remain inside the snow cover. Compacted by subsequent snowfalls, the snow gradually turns into firn and later into ice. Deposits thus trapped in the glacier ice form invaluable archives of past climates and original atmospheric composition. These archives ...Doctoral Thesis -
3D Shape Fabrication from Flat Material Sheets
(2020)Digital fabrication has been a research area of huge interest in recent years, since it enables the fast creation of objects from digital models. Next to state-of-the-art technologies like 3D printing or more traditional CNC milling, techniques focused on flat materials are of interest, since modern laser cutters are fast and afford a large variety of cheap and durable materials, like plywood, acrylic glass or fabric. Previous methods for ...Doctoral Thesis -

Adsorption and Ultrafiltration as Techniques for Value Addition to Plant-Based By-Products
(2021)The growth of the global population to 8.5 – 10 billion people by 2050 entails an increased demand for food in the forthcoming decades. Our incumbent world food system is marked by tremendous inefficiencies in the utilization of agricultural commodities for food production. The accumulation of vast quantities of solid and liquid food processing by products along the food supply chain poses a serious environmental burden. The expansion of ...Doctoral Thesis -
The role of Policies for the Diffusion of Low-Carbon Technologies and their System Integration
(2020)Climate change has become one of the grand challenges for humankind. With the 2019 IPCC report demonstrating the urge to keep global warming below 1.5°C and the increasing public awareness triggered by grassroots movements such as Fridays For Future, in many nations, policymakers began to pledge to go carbon neutral by 2050. The energy sector is responsible for two-thirds of global carbon emissions, making its decarbonization pivotal ...Doctoral Thesis
