We present scanning gate microscopy (SGM) studies of graphene Hall-cross devices where bi-layer graphene (2LG) regions show unexpected signal inversion relative to single-layer graphene (1LG), an observation reproduced via finite element modelling of the current densities. This is attributed to gate-induced charge carrier redistribution between the...
Topology optimization of natural convection problems is computationally expensive, due to the large number of degrees of freedom (DOFs) in the model and its two-way coupled nature. Herein, a method is presented to reduce the computational effort by use of a reduced-order model governed by simplified physics. The proposed method models the fluid flo...
The presence of SO2 in diesel exhaust gases causes severe deactivation of the Cu–CHA catalysts for the reduction of NOx by selective catalytic reduction with ammonia (NH3-SCR). The deactivation of Cu–CHA catalysts after exposure to SO2 at 550 °C for 0.5, 4, 8, 16 and 32 h, and subsequent regeneration in SO2-free gas at 550 °C was related to the sit...
Purpose - In recent decades there has been a focus on reducing the overall emissions from the built environment, which increases the complexity of the building design process. More specialized knowledge, a greater common understanding and more cooperation between the stakeholders are required. Interdisciplinary design teams need simple and intuitiv...
Multi-walled carbon nanotubes (MWCNT) are widely used nanomaterials that cause pulmonary toxicity upon inhalation. The physicochemical properties of MWCNT vary greatly, which makes general safety evaluation challenging to conduct. Identification of the toxicity-inducing physicochemical properties of MWCNT is therefore of great importance. We have e...
The Danish Fisher-Researcher-Network is organized by the trade organizations: The Danish Fisheries Association Producer Organization and the Danish Pelagic Producers Organization as well as the research institute, DTU Aqua. The European Maritime and Fisheries Fund and the Fisheries Agency finance the project.
The purpose of the project is to support...
Mechanistic models are simplifications of bio-physical systems, for which the true values of the model parameters are sometimes unknown. Therefore, before using model-based predictions to study or improve a process, it is essential to ensure that the outputs of the model are reliable. This paper covers the development and application of a framework...
