Richieri, Beatrice (author), Bittner, Daniel (author), Hartmann, Andreas (author), Benettin, Paolo (author), van Breukelen, B.M. (author), Labat, David (author), Chiogna, Gabriele (author)Hydrochemical data of karst springs provide valuable insights into the internal hydrodynamical functioning of karst systems and support model structure identification. However, the collection of high-frequency time series of major solute species is limited by analysis costs. In this study, we develop a method to retrieve the individual solute...journal article 2023

Tuluk, A. (author), Brouwer, J.C. (author), van der Zwaag, S. (author)BiFeO <sub>3</sub> is a multiferroic material with a perovskite structure that has a lot of potential for use in sensors and transducers. However, obtaining pure single-phase BiFeO <sub>3</sub> ceramic with a low electrical conductivity via solid-state reactions remains a problem that limits its application. In this work, the suppression of...journal article 2022

(author), van der Stam, W. (author)Metal-halide perovskite nanocrystals show promise as the future active material in photovoltaics, lighting, and other optoelectronic applications. The appeal of these materials is largely due to the robustness of the optoelectronic properties to structural defects. The photoluminescence quantum yield (PLQY) of most types of perovskite...journal article 2020

Rems, L. (author), Viano, Marilyne (author), Kasimova, Marina A. (author), Miklavčič, Damijan (author), Tarek, Mounir (author)Electroporation or electropermeabilization is a technique that enables transient increase in the cell membrane permeability by exposing cells to pulsed electric field. However, the molecular mechanisms of the long-lived cell membrane permeability, which persists on the minutes time scale after the pulse treatment, remain elusive. Experimental...journal article 2019

Wang, H. (author), Yang, Jun (author), Liao, Hui (author), Chen, Xianhua (author)Electrically conductive asphalt concrete has the potential to satisfy multifunctional applications. Designing such asphalt concrete needs to balance the electrical and mechanical performance of asphalt concrete. The objective of this study is to design electrically conductive asphalt concrete without compromising on the mechanical properties...journal article 2016

Tsekmes, I.A. (author)The addition of microsized fillers to polymers, in order to tailor their properties, has been extensively used in many industrial applications since the 1960s. The same approach applies to the field of electrical insulation. Epoxy resin is a widely used polymer in the electrical power sector, but it is usually loaded with microsized fillers,...doctoral thesis 2016

(author)Poly(2-nonyl-2-oxazoline)80-stat-poly(2-dec-9?-enyl-2-oxazoline)20 and poly(2-dec-9?-enyl-2-oxazoline)100 can be synthesized from the cationic ring-opening polymerization of monomers that can be derived from fatty acids from renewable resources. These (co)poly(2-oxazoline)s can be crosslinked with di- and trifunctional mercapto compounds using...journal article 2015

Calado, V.E. (author), Schneider, G.F. (author), Theulings, A.M.M.G. (author), Dekker, C. (author), Vandersypen, L.M.K. (author)We study the formation of wrinkles in graphene upon wet transfer onto a hydrophilic target substrate, whereby draining of water appears to play an important role. We are able to control the orientation of the wrinkles by tuning the surface morphology. Wrinkles are absent in flakes transferred to strongly hydrophobic substrates, a further...journal article 2012

(author)Electrical conductance through InAs nanowires is relevant for electronic applications as well as for fundamental quantum experiments. Here, we employ nominally undoped, slightly tapered InAs nanowires to study the diameter dependence of their conductance.

(author)We present a method to make Pt nanometer-spaced electrodes that are free of metallic particles and stable at ambient conditions. The nanogaps are fabricated using feedback-controlled electromigration to form few-atom contacts. When performing this procedure at elevated temperatures (>420?K), the Pt contacts undergo self-breaking so that...journal article 2009

Vroubel, M. (author), Rejaei, B. (author)The spin-wave spectrum of a ferromagnetic stripe placed above a metallic layer with finite conductivity is studied by using the magnetostatic Green’s function formalism. It is shown that the frequency and linewidth of the resonances are uniquely determined by complex, mode-dependent demagnetization factors. The formalism developed is used to...journal article 2008

Khalili Amiri, P.K. (author), Rejaei, B. (author), Vroubel, M. (author), Zhuang, Y. (author)The authors report on the observation of nonreciprocal spin wave propagation in a thin ( ? 200?nm) patterned Ni–Fe stripe. The spin wave transmission spectrum is measured using a pair of microstrip lines as antennas. The nonreciprocity of surface wave dispersion brought about by an adjacent aluminum ground leads to a nonreciprocal coupling of...journal article 2007
