Toet, A.S. (author), van Kuijk, J.I. (author), Boersma, K. (author), Santema, S.C. (author)Future mobility systems will likely incorporate more multimodal journeys. These multimodal journeys integrate multiple modes of transport, and their higher future prevalence highlights the importance of paying attention to the modality transfers within journeys. To carefully facilitate these transfers, we advocate the creation of passenger...conference paper 2023

Wang, J. (author), Yan, Xin ping (author), Boersma, B.J. (author), Lu, Ming jian (author), Liu, Xiaohua (author)Printed circuit heat exchangers (PCHE) are designed to improve heat recovery and energy saving in supercritical CO<sub>2</sub> (S-CO<sub>2</sub>) power cycles. In the current study, a modified channel PCHE is proposed based on the regular straight channel and a zigzag channel. The thermal–hydraulic performance of four different types of PCHE...journal article 2023

Ozmen, Yucel (author), Boersma, B.J. (author)An experimental study was conducted to search the reduction of friction in fully developed turbulent pipe flow using different types of polyacrylamides as friction reducing polymers.

(author)Antiviral signalling, which can be activated in host cells upon virus infection, restricts virus replication and communicates infection status to neighbouring cells. The antiviral response is heterogeneous, both quantitatively (efficiency of response activation) and qualitatively (transcribed antiviral gene set). To investigate the basis of...journal article 2023

van Brakel, Rosamunde (author), Kudina, O. (author), Fonio, Chiara (author), Boersma, Kees (author)This paper focuses on two examples of the introduction and use of COVID-19 contact tracing apps in The Netherlands (CoronaMelder) and Belgium (Coronalert). It aims to offer a critical, sociotechnical perspective on tracing apps to understand how social, technical, and institutional dimensions form the ingredients for increasing surveillance....journal article 2022

(author)Production of mature oil fields emits significant amount of CO<sub>2</sub> related to circulation and handling of large volumes of gas and water. This can be reduced either by (1) using a low-carbon energy source and/or (2) reducing the volumes of the non-hydrocarbon produced/injected fluids. This paper describes how improved oil recovery...journal article 2022

(author)In response to the outbreak of SARS-CoV-2, many governments decided in 2020 to impose lockdowns on societies. Although the package of measures that constitute such lockdowns differs between countries, it is a general rule that contact between people, especially in large groups of people, is avoided or prohibited. The main reasoning behind these...journal article 2022

(author)We develop a method based on concept of exergy-return on exergy-investment (ERoEI) to determine the energy efficiency and CO<sub>2</sub> footprint of polymer and surfactant enhanced oil recovery (EOR). This integrated approach considers main surface and subsurface elements of the chemical EOR methods. The main energy investment in oil...conference paper 2022

loddo, M. (author), Boersma, Foekje (author), Kleppe, Martijn (author), Vingerhoets, Karin (author)In the late 1990s, the explosion of electronic resources resulted in large-scale digitisation projects amid the need for the preservation of digital information. The KB, National Library of the Netherlands, has been actively involved in these activities. Now, it is proposing better ways to both preserve physical library materials and improve...journal article 2021

Natural Fracture Network Characterisation: Numerical modelling, outcrop analysis and subsurface dataBoersma, Q.D. (author)Responsibly using the subsurface for geo-energy extraction or storage requires an accurate understanding of the static and dynamic behaviour of the targeted reservoirs. While mostly dependent on intrinsic rock properties (e.g. porosity and permeability), this behaviour is also believed to be significantly impacted by the presence of natural...doctoral thesis 2020
