Jansen, E. (author), Pereira Machado, J.D. (author), Blanter, Y.M. (author)We consider an electromechanical system in which a microwave cavity is coupled to a mechanical resonator, with a mechanical frequency twice the microwave frequency. In this regime, the effective photon-phonon interaction is equivalent to that of a degenerate parametric amplifier, instead of the typical radiation pressure interaction. If the...journal article 2019

Tirumalasetty, G.K. (author), Fang, C.M. (author), Jansen, J. (author), Yokosawa, T. (author), Boeije, M.J.F. (author), Sietsma, J. (author), Van Huis, M.A. (author), Zandbergen, H.W. (author)Chromium (Cr), Manganese (Mn), and Carbon (C) are well known alloying elements used in technologically important alloy steels and advanced high strength steels. It is known that binary CrCx and MnCx carbides can be formed in steels, but in this study we reveal for the first time that Cr and Mn were found combined in novel ternary cementite type ...journal article 2014

Jansen, K. (author), Van Soest, G. (author), Van der Steen, A.F.W. (author)The vulnerable atherosclerotic plaque is believed to be at the root of the majority of acute coronary events. Even though the exact origins of plaque vulnerability remain elusive, the thin-cap fibroatheroma, characterized by a lipid-rich necrotic core covered by a thin fibrous cap, is considered to be the most prominent type of vulnerable plaque...journal article 2014

Jansen, K. (author), Wu, M. (author), Van der Steen, A.F.W. (author), Van Soest, G. (author)Spectroscopic intravascular photoacoustic imaging (sIVPA) has shown promise to detect and distinguish lipids in atherosclerotic plaques. sIVPA generally utilizes one of the two high absorption bands in the lipid absorption spectrum at 1.2 ?m and 1.7 ?m. Specific absorption signatures of various lipid compounds within the bands in either...journal article 2014

(author), De Kleijn, D.P.V. (author), Van Soest, G. (author)The natural history of atherosclerosis is marked by changes in the lipid biochemistry in the diseased arterial wall. As lesions become more vulnerable, different cholesterol species accumulate in the plaque. Understanding unstable atherosclerosis as a pharmacological and interventional therapeutic target requires chemically specific imaging of...journal article 2014

Jansen, K. (author), Wu, M. (author), Van der Steen, A.F.W. (author), Van Soest, G. (author)The presence of lipids in atherosclerotic coronary lesions is an important determinant of their potential to trigger acute coronary events. Spectroscopic intravascular photoacoustic imaging (sIVPA) has the potential to automatically detect lipids in atherosclerotic lesions. For realtime in vivo imaging, limiting the number of excitation...journal article 2013

(author)A transmission electron microscopy study was conducted on nanoprecipitates formed in Ti microalloyed transformation-inducedplasticity-assisted steels, revealing the presence of Ti(N), Ti2CS and a novel type of ultra-fine Fe(C) precipitate. The matrix/precipitate orientation relationships, sizes and shapes were investigated in detail. The...journal article 2012

(author)We demonstrate the feasibility of intravascular ultrasound (IVUS) chirp imaging as well as chirp reversal ultrasound contrast imaging at intravascular ultrasound frequency. Chirp excitations were emitted with a 34?MHz single crystal intravascular transducer and compared to conventional Gaussian-shaped pulses of equal acoustic pressure. The...journal article 2012

Fang, C.M. (author), Van Huis, M.A. (author), Jansen, J. (author), Zandbergen, H.W. (author)Although Fe2C and Fe2N are technologically important materials, the exact nature of the chemical bonding of C and N atoms and the related impact on the electronic properties are at present unclear. Here, results of first-principles electronic structure calculations for Fe2X (X = C, N) phases are presented. The electronic structure calculations...journal article 2011
