Niklaß, Malte (author), Grewe, V. (author), Gollnick, V (author)Approximately two third of aviation’s climate impact is caused by non-CO2 effects, like the production of ozone and the formation of contrail-cirrus clouds, which can be effectively prevented by re-routing flights around highly climate-sensitive areas. Although climate-optimized re-routing results in slightly longer flight times, increased fuel...abstract 2020

Comparison of various aircraft routing strategies using the air traffic simulation model airtraf 2.0Yamashita, H. (author), Yin, F. (author), Grewe, V. (author), Jockel, P. (author), Matthes, Sigrun (author), Kern, Bastian (author), Dahlmann, K. (author), Frömming, C. (author)A climate-optimized routing is expected as an operational measure to reduce the climate impact of aviation, whereas this routing causes extra aircraft operating costs. This study performs some air traffic simulations of nine aircraft routing strategies which include the climate-optimized routing, and examines characteristics of those routings. A...abstract 2020

Dahlmann, K. (author), Matthes, Sigrun (author), Yamashita, H. (author), Unterstrasser, S. (author), Grewe, V. (author), Marks, Tobias (author)An operational measure to aim for mitigation of aviation climate impact that is inspired by migrant birds is to fly in aerodynamic formation. This operational measure adapted to human aircraft would eventually save fuel and is, therefore, expected to reduce the climate impact of aviation. As this method changes beside the total emission also the...abstract 2020

Yin, F. (author), Grewe, V. (author), Gierens, K. (author)iation is responsible for approximately 5% of global warming and is expected to increase substantially in the future. In the face of the continuing expansion of air traffic, mitigation of the aviation’s climate impact becomes challenging, but imperative. Among various mitigation options, hybrid electric aircraft (HEA) has drawn intensive...abstract 2020

Emmerig, J. (author), Jockel, P. (author), Grewe, V. (author)Supersonic transport was the subject of intense debate in the 1970s and commercial operation was eventually abandoned until recently due to economic and environmental concerns. Flight emissions at stratospheric altitude differ from tropospheric emissions mainly in terms of longevity. Long lifetimes of chemically reactive emissions, especially in...abstract 2020

Chappin, E.J.L. (author), De Vries, Laurens (author)We simulate climate and energy policy for the EU using a flexible and modular agent-based modelling approach, we named Energy Modelling Laboratory (EMLab). The agent-based model focuses on investment in power generation and studies long run effects of various interacting European energy policies, and incorporates differences between countries....abstract 2020

Cheng, L. (author), Xin, H. (author), Groves, R.M. (author), Veljkovic, M. (author)S460 steel is increasingly used in civil engineering, especially in a harsh environment such as offshore structures [1]. Material damage is inevitable for structures subjected to static and dynamic loads during their technical life time. Thus, monitoring material damage is important for providing information regarding critical damage of in...abstract 2020

Ruan, J. (author), Ghose, R. (author), Mulder, W.A. (author)Modelling dynamic rupture is essential to correctly describe the process of induced seismicity. Defmod, an open-source finite-element code featuring quasi-static loading, co-seismic volumetric strain, and dynamic rupture, is used to simulate the entire chain of induced seismicity, from pressure evolution due to fluid injection and extraction,...abstract 2020

Giagka, Vasiliki (author)In a world where medicine is becoming more personalised the promise of Bioelectronic Medicine is that tiny implants will deliver energy in the form of electrical impulses, replacing pharmaceuticals, their conventional chemical counterparts. But how can we develop such tiny smart and autonomous implants that (need to) seamlessly interact with the...abstract 2020

Oosterlo, P. (author), Hofland, Bas (author), van der Meer, J.W. (author), Overduin, Maarten (author), Steendam, Gosse Jan (author)Oosterlo et al. (2019) developed a system using two terrestrial laser scanners, which can measure run-up heights, depths and velocities of waves on a dike in field situations. The system has now been placed next to two overtopping tanks on a dike in the Eems-Dollard estuary in the Netherlands to measure during actual severe winter storms. The...abstract 2020

Li, K. (author), Wolf, K.H.A.A. (author), Rossen, W.R. (author)Gas-injection EOR processes have poor sweep efficiency due to conformance problems including channelling, gravity override and fingering. In naturally fractured reservoirs, sweep efficiency is further jeopardized, because gas breaks through fractures first, leaving most oil behind in the matrix. Strong foam can be created in fractures[1][2],...abstract 2020

Li, K. (author), Wolf, K.H.A.A. (author), Rossen, W.R. (author)Gas injection often suffers from the poor sweep efficiency because of conformance problems, including gravity override, viscous fingering and channelling, as gas has a lighter density and a lower viscosity compared to in-situ fluids. Foam, by encapsulating the gas into separate bubbles in surfactant-contained liquid thin films (lamella), can...abstract 2020

While CO2 has a long atmospheric residence time and is uniformly distributed in the atmosphere, non-CO2 gases, particles and their products have short atmospheric residence times and are heterogeneously distributed. Their climate effects depend on chemical and meteorological background...abstract 2020
