Visualizing the pH profile inside the catholyte of a CO2 electrolysis cell

Hoogland, Maxime (author)

CO2 electrolysis to form CO with the use of electricity from renewable sources is a promising technique in closing the carbon cycle. Via the electrochemical reduction CO2 can be converted into different hydrocarbon products. These value-added products are for example CO, HCOOH, CH3OH or C2H4. The direct electrochemical route of CO2 reduction is...

Back to the Commons: Introducing Regenerative Agricultural Networks in Northwestern Europe

Shekar, Kirthan (author), Nguyen, Nancy (author), van der Steen, Raven (author), Saridou, Stefania (author), Hoogland, Willemijn (author)

For the last decades, technologies, new agricultural trade policies, environmental restrictions, high pressure through economic competition in combination with a sharp competition of land lead to the development of intensive farming. As a result, patchy landscapes have been replaced by monofunctional, homogeneous agricultural landscapes that...

Direct Imaging of Local pH Reveals Bubble-Induced Mixing in a CO₂ Electrolyzer

Baumgartner, L.M. (author), Kahn, A.P. (author), Hoogland, Maxime (author), Bleeker, J.J. (author), Jager, W.F. (author), Vermaas, D.A. (author)

Electrochemical CO₂ reduction poses a promising pathway to produce hydrocarbon chemicals and fuels without relying on fossil fuels. Gas diffusion electrodes allow high selectivity for desired carbon products at high current density by ensuring a sufficient CO₂ mass transfer rate to the catalyst layer. In addition to CO...

Image-based Video Search Engine: Data Compression and Nearest Neighbour Search

Korevaar, Matthijs (author), Hoogland, Lars (author)

One of the main problems with Instance-level Image Retrieval in video data is that for longer query videos or large amount of image queries, comparing all of the query images to every extracted frame is time-inefficient. This thesis aims to solve this problem by implementing Nearest Neighbour Search (NNS) algorithms and data compression methods,...

Characterization and Mitigation of High-Confidence Errors Through the Use of Human-In-The-Loop Methods: Domain Expert Driven Approach to Model Development

Hoogland, Pavel (author)

In the use of Machine Learning systems, attaining the trust of those that are the end-users can often be difficult. Many of the current state-of-the-art systems operate as Black-Boxes. Errors produced by these Black-Box systems, without further explanation as to why these decisions were made, will deteriorate trust. This effect is especially...

NINscope, a versatile miniscope for multi-region circuit investigations

de Groot, Andres (author), van den Boom, Bastijn Jg (author), van Genderen, Romano M. (author), Coppens, Joris (author), van Veldhuijzen, John (author), Bos, Joop (author), Hoedemaker, Hugo (author), Negrello, M.J.F. (author), Willuhn, Ingo (author), De Zeeuw, Chris I. (author), Hoogland, Tycho M. (author)

Miniaturized fluorescence microscopes (miniscopes) have been instrumental to monitor neural signals during unrestrained behavior and their open-source versions have made them affordable. Often, the footprint and weight of open-source miniscopes is sacrificed for added functionality. Here, we present NINscope: a light-weight miniscope with a...

Spatial patterns in ⁸⁷Sr/⁸⁶Sr ratios in modern human dental enamel and tap water from the Netherlands: Implications for forensic provenancing

Kootker, Lisette M. (author), Plomp, E. (author), Ammer, Saskia T.M. (author), Hoogland, Vera (author), Davies, Gareth R. (author)

The analysis of strontium isotope ratios in human dental enamel has become important in the fields of archaeological and forensic science for determining provenance and hence mobility. The prerequisite for the approach relies on a correlation between dietary Sr intake and the underlying local geology. This premise is brought into question for...

A Distributed Public Key Infrastructure for the IoT

Hoogland, Mathijs (author)

The role of Internet of Things (IoT) devices is becoming larger in our day-to-day life. More and more, devices are used to help with simple tasks in our lives. Little computers are installed in a large variety of consumer products and are often connected to the internet. The large increase of these “resource-constrained” devices that are...

Earth frozen orbits: Design, injection and stability

Hoogland, J. (author)

A frozen orbit is an orbit chosen such that the effect of perturbations on (a combination of) the mean orbital elements is minimized. The concept first appeared in literature in 1978, and was applied that same year to the Seasat mission. This altimetry mission featured strict requirements on the accuracy of the altitude of the satellite above...

Microsecond-sustained lasing from colloidal quantum dot solids

Adachi, Michael M. (author), Fan, Fengjia (author), Sellan, Daniel P. (author), Hoogland, Sjoerd (author), Voznyy, Oleksandr (author), Houtepen, A.J. (author), Parrish, Kevin D. (author), Kanjanaboos, Pongsakorn (author), Malen, Jonathan A. (author), Sargent, Edward H. (author)

Colloidal quantum dots have grown in interest as materials for light amplification and lasing in view of their bright photoluminescence, convenient solution processing and size-controlled spectral tunability. To date, lasing in colloidal quantum dot solids has been limited to the nanosecond temporal regime, curtailing their application in...

Now, later, or both: A closed-form optimal decision for a risk-averse buyer

Hoogland, J. (author), de Weerdt, M.M. (author), la Poutré, J.A. (author)

Motivated by the energy domain, we examine a risk-averse buyer that has to purchase a fixed quantity of a continuous good. The buyer has two opportunities to buy: now or later. The buyer can spread the quantity over the two timeslots in any way, as long as the total quantity remains the same. The current price is known, but the future price...
