Shani-Kadmiel, Shahar (author), Assink, Jelle D. (author), Smets, P.S.M. (author), Evers, L.G. (author)In this study we analyze infrasound signals from three earthquakes in central Italy. The M<sub>w</sub> 6.0 Amatrice, M<sub>w</sub> 5.9 Visso, and M<sub>w</sub> 6.5 Norcia earthquakes generated significant epicentral ground motions that couple to the atmosphere and produce infrasonic waves. Epicentral seismic and infrasonic signals are...journal article 2018

Evers, J.M. (author), Tavasszy, Lorant (author), van Duin, Ron (author), Schott, D.L. (author), Gorte, Frank (author)Food waste and incomplete orders at online supermarkets mainly occur due to inaccurate demand forecasting which leads to incorrect ordering of products. The objective of this study is to develop an accurate demand forecast model at product-level based on historical customer order data, give recommendations on implementation and describe impact...conference paper 2018

(author), Siebbeles, L.D.A. (author)Carrier multiplication is a process in which one absorbed photon excites two or more electrons. This is of great promise to increase the efficiency of photovoltaic devices. Until now, the factors that determine the onset energy of carrier multiplication have not been convincingly explained. We show experimentally that the onset of carrier...journal article 2018

Kulkarni, A. (author), Evers, W.H. (author), Tomić, Stanko (author), Beard, Matthew C. (author), Vanmaekelbergh, Daniel (author), Siebbeles, L.D.A. (author)Carrier multiplication (CM) is a process in which a single photon excites two or more electrons. CM is of interest to enhance the efficiency of a solar cell. Until now, CM in thin films and solar cells of semiconductor nanocrystals (NCs) has been found at photon energies well above the minimum required energy of twice the band gap. The high...journal article 2018

(author)Control over the charge density is very important for implementation of colloidal semiconductor nanocrystals into various optoelectronic applications. A promising approach to dope nanocrystal assemblies is charge injection by electrochemistry, in which the charge compensating electrolyte ions can be regarded as external dopant ions. To gain...journal article 2018

(author)We use the electrodeless time-resolved microwave conductivity (TRMC) technique to characterize spin-crossover (SCO) nanoparticles. We show that TRMC is a simple and accurate means for simultaneously assessing the magnetic state of SCO compounds and charge transport information on the nanometer length scale. In the low-spin state from liquid...journal article 2018

(author), Longo, Alessandro (author), Houtepen, A.J. (author)The processes that govern radiative recombination in ternary CuInS<sub>2</sub> (CIS) nanocrystals (NCs) have been heavily debated, but recently, several research groups have come to the same conclusion that a photoexcited electron recombines with a localized hole on a Cu-related trap state. Furthermore, it has been observed that single CIS...journal article 2018

Evers, L.G. (author), Wapenaar, C.P.A. (author), Heaney, KD (author), Snellen, M. (author)The propagation of acoustic waves in the ocean strongly depends on the temperature. Lowfrequency acoustic waves can penetrate the ocean down to depths where few in situ measurements are available. It is therefore attractive to obtain a measure of the deep ocean temperature from acoustic waves. The latter is especially true if the ambient...journal article 2017

(author), Lv, Cheng (author)We investigate the spatial coherence of underwater ambient noise using a yearlong time-series measured off Ascension Island. Qualitative agreement with observed cross-correlations is achieved using a simple range-dependent model, constrained by earlier, active tomographic studies in the area. In particular, the model correctly predicts the...journal article 2016

(author)Charge transfer in semiconductor heterojunctions is largely governed by the offset in the energy levels of the constituent materials. Unfortunately, literature values for such energy level offsets vary widely and are usually based on energy levels of the individual materials rather than of actual heterojunctions. Here we present a new method...journal article 2016
