Kleinherenbrink, M. (author), Naeije, M.C. (author), Slobbe, D.C. (author), Egido, Alejandro (author), Smith, Walter (author)This paper applies the Fully-Focussed SAR (FF-SAR) algorithm to CryoSat-2 full-bit-rate data to measure water levels of lakes and canals in the Netherlands, and validates these measurements by comparing them to heights measured by gauges. Over Lake IJssel, a medium-sized lake, the FF-SAR height is biased about 6 cm below the gauge height, and...journal article 2020

Fromentèze, Thomas (author), Yurduseven, Okan (author), Berland, Fabien (author), Decroze, Cyril (author), Smith, David R. (author), Yarovoy, Alexander (author)In this paper, we describe the recent development of new algorithms applied to short-range radar imaging. Facing the limitations of classical backpropagation algorithms, the use of techniques based on Fast Fourier Transforms has led to substantial image computation accelerations, especially for Multiple-Input Multiple-Output systems. The...journal article 2020

Vos, Johannes G. (author), Venugopal, A. (author), Smith, W.A. (author), Koper, Marc T.M. (author)Hydrogen production from seawater electrolysis is highly promising for the capture and storage of intermittent renewable energy, but is hindered by the possibility of unwanted reactions at the anode. The oxidation reactions of chloride and (to a lesser extent) bromide, which can occur in parallel to the evolution of oxygen, lead to...journal article 2020

Smith, Kathleen Beth (author), Wehrli, Monika (author), Japaridze, A. (author), Assenza, Salvatore (author), Dekker, C. (author), Mezzenga, Raffaele (author)The fine interplay between the simultaneous stretching and confinement of amyloid fibrils is probed by combining a microcapillary setup with atomic force microscopy. Single-molecule statistics reveal how the stretching of fibrils changed from force to confinement dominated at different length scales. System order, however, is solely ruled by...journal article 2020

Bae, D. (author), Kanellos, Gerasimos (author), Wedege, Kristina (author), Dražević, Emil (author), Bentien, Anders (author), Smith, W.A. (author)MoOX is commonly considered to be a high work-function semiconductor. From x-ray photoelectron spectroscopy and photoelectrochemical analysis, it is shown that MoOX can be considered as an effective hole transfer layer for the GaP-based device. Specifically, in the absence of carbon contamination using an ion beam cleaning step, the oxygen...journal article 2020

(author)Inhomogeneities in the refractive index of a biological microscopy sample can introduce phase aberrations, severely impairing the quality of images. Adaptive optics can be employed to correct for phase aberrations and improve image quality. However, conventional adaptive optics can only correct a single phase aberration for the whole field of...journal article 2020
