Selectivity control between reverse water-gas shift and fischer-tropsch synthesis in carbon-supported iron-based catalysts for CO₂ hydrogenation

Meng, Weixin (author), de Jong, B. (author), van de Bovenkamp, Henk V. (author), Boer, Gert Jan (author), Leendert Bezemer, G. (author), Dugulan, A.I. (author), Xie, Jingxiu (author)

CO₂ hydrogenation to chemicals and fuels has the potential to alleviate CO₂ emissions and displace fossil resources simultaneously via consecutive RWGS and FTS reactions, also known as CO₂-FTS. As Fe-based catalysts are active and selective for both reactions, their bifunctionality requires a delicate balance...

Oceanic carbon capture through electrochemically induced in situ carbonate mineralization using bipolar membrane

sharifian, rezvan (author), Boer, L. (author), Wagterveld, R. M. (author), Vermaas, D.A. (author)

Bipolar membrane electrodialysis (BPMED) can provide a sustainable route to capture the oceanic-dissolved inorganic carbon (DIC) using an electrochemical pH-swing concept. Previous works demonstrated how gaseous CO₂ (through acidification) can be obtained from ocean water, and how carbonate minerals can be provided via ex situ...

Simultaneous Quantification of the Concentration and Carbon Isotopologue Distribution of Polar Metabolites in a Single Analysis by Gas Chromatography and Mass Spectrometry

Evers, Bernard (author), Gerding, Albert (author), Boer, Theo (author), Heiner-Fokkema, M. Rebecca (author), Jalving, Mathilde (author), Wahl, S.A. (author), Reijngoud, Dirk Jan (author), Bakker, Barbara M. (author)

13C-isotope tracing is a frequently employed approach to study metabolic pathway activity. When combined with the subsequent quantification of absolute metabolite concentrations, this enables detailed characterization of the metabolome in biological specimens and facilitates computational time-resolved flux quantification. Classically, a 13C...

A risk field-based metric correlates with driver's perceived risk in manual and automated driving: A test-track study

Kolekar, S.B. (author), Petermeijer, S.M. (author), Boer, E.R. (author), de Winter, J.C.F. (author), Abbink, D.A. (author)

Quantifying drivers’ perceived risk is important in the design and evaluation of the behaviour of automated vehicles (AVs) and in predicting takeovers by the driver. A ‘Driver's Risk Field’ (DRF) function has been previously shown to be able to predict manual driving behaviour in several simulated scenarios. In this paper, we tested if the...

Analysis of attenuation coefficient estimation in Fourier-domain OCT of semi-infinite media

Ghafaryasl, B. (author), Vermeer, Koenraad A. (author), Kalkman, J. (author), Dore-Callewaert, T.W.J. (author), Boer, Johannes F.D.E. (author), van Vliet, L.J. (author)

The attenuation coefficient (AC) is an optical property of tissue that can be estimated from optical coherence tomography (OCT) data. In this paper, we aim to estimate the AC accurately by compensating for the shape of the focused beam. For this, we propose a method to estimate the axial PSF model parameters and AC by fitting a model for an...

What determines drivers’ speed?: A replication of three behavioural adaptation experiments in a single driving simulator study

Melman, T. (author), Abbink, D.A. (author), van Paassen, M.M. (author), Boer, E.R. (author), de Winter, J.C.F. (author)

We conceptually replicated three highly cited experiments on speed adaptation, by measuring drivers’ experienced risk (galvanic skin response; GSR), experienced task difficulty (self-reported task effort; SRTE), and safety margins (time-to-line-crossing; TLC) in a single experiment. The three measures were compared using a nonparametric index...

In this experimental study the segregation behavior for fluidized mixtures of spherical and cylindrical particles is investigated. In industry, fluidization of particles featuring a wide range of shapes is common in various applications such as biomass gasification, drying applications, food processing and production of pharmaceuticals....

A topology of shared control systems: Finding common ground in diversity

Abbink, D.A. (author), Carlson, Tom (author), Mulder, M. (author), de Winter, J.C.F. (author), Aminravan, Farzad (author), Gibo, T.L. (author), Boer, E.R. (author)

Shared control is an increasingly popular approach to facilitate control and communication between humans and intelligent machines. However, there is little consensus in guidelines for design and evaluation of shared control, or even in a definition of what constitutes shared control. This lack of consensus complicates cross fertilization of...

Does the Projected-Hand-Illusion Help in Teleoperation?

Wajon, Lloyd (author), van Paassen, M.M. (author), Abbink, D.A. (author), Boer, E.R. (author), Mulder, Max (author)

A body illusion, commonly known in the form of the “Rubber Hand Illusion”, is an illusion wherein visual inputs on an inanimate object and simultaneous tactile inputs on a part of the body lead to a situation where the inanimate object is identified as the body part. This study investigated the possibility of inducing a body illusion during a...

Proof load testing of reinforced concrete slab bridges in the Netherlands

Lantsoght, E.O.L. (author), van der Veen, C. (author), Boer, A. de (author), Hordijk, D.A. (author)

The bridges built during the development of the Dutch road network after the Second World War are reaching their originally devised service life. A large subset of the Dutch bridge stock consists of reinforced concrete slab bridges. This bridge type often rates insufficient according to the recently introduced Eurocodes. Therefore, more suitable...

Manual control cybernetics aims to understand and describe how humans control vehicles and devices using mathematical models of human control dynamics. This “cybernetic approach” enables objective and quantitative comparisons of human behavior, and allows a systematic optimization of human control interfaces and training...

Shear capacity of the Ruytenschildt bridge

Lantsoght, E.O.L. (author), van der Veen, C. (author), Boer, A. de (author)

In August 2014, the Ruytenschildt Bridge, a reinforced concrete solid slab bridge (reinforced with plain bars) in the Friesland province in the Netherlands was tested until failure. One of the goals of proof loading and testing this bridge to failure, was to study the failure mode of existing slab bridges. The combination of smaller shear...

Defining loading criteria for proof loading of existing reinforced concrete bridges

Koekkoek, R.T. (author), Lantsoght, E.O.L. (author), Yang, Y. (author), Boer, A. de (author), Hordijk, D.A. (author)

As the bridge stock in The Netherlands and Europe is ageing, various methods to analyse existing bridges are bemg studied. Proof loading of bridges is an option to study the capacity when crucial information about the structure is lacking. This information could be related to the material (for example, the effect of alkali-silica reaction on the...

Fundamental issues in manual control cybernetics

Mulder, Max (author), Pool, D.M. (author), Abbink, D.A. (author), Boer, E.R. (author), van Paassen, M.M. (author)

Manual control cybernetics aims to understand and describe how humans control vehicles and devices, such that more effective human-machine interfaces can be designed. Current cybernetics theory is primarily based on technology and analysis methods developed in the 1960s and has shown to be limited in its capability to capture the full breadth of...

Pyruvate and acetyl-coenzyme A, located at the interface between glycolysis and TCA cycle, are important intermediates in yeast metabolism and key precursors for industrially relevant products. Rational engineering of their supply requires knowledge of compensatory reactions that replace predominant pathways when these are inactivated. This...

Cancer develops through a multistep process in which normal cells progress to malignant tumors via the evolution of their genomes as a result of the acquisition of mutations in cancer driver genes. The number, identity and mode of action of cancer driver genes, and how they contribute to tumor evolution is largely unknown. This study deployed...
