Mayer, F. (author), Tiruvadi Krishnan, S. (author), Schuhle, DT (author), Eliseeva, Svetlana V. (author), Petoud, Stephane (author), Toth, Eva (author), Djanashvili, K. (author)Self-aggregating calix[4]arenes carrying four DOTA ligands on the upper rim for stable complexation of paramagnetic GdIII-ions have already been proposed as MRI probes. In this work, we investigate the luminescence properties of TbIII-DOTA-calix[4]arene-4OPr containing four propyl-groups and compare them with those of the analog substituted with...journal article 2018

(author)Submicron- and micron-scale structures of composite hydrogels based on bacterial cellulose (BC) and polyacrylamide (PAAm) were studied by spin-echo small-angle neutron scattering (SESANS) and cryo-scanning electron microscopy (cryo-SEM). These hydrogels possessing the structure of interpenetrating polymer network were synthesized via free...journal article 2017

Jia, Y. (author), Or, S.W. (author), Chan, H.L.W. (author), Jiao, J. (author), Luo, H. (author), Van der Zwaag, S. (author)We report a power supply-free, bidirectional electric current-voltage converter based on a coil-wound laminated composite of magnetostrictive alloy and piezoelectric crystal. An electric current applied to the coil induces a magnetic field, resulting in an electric voltage from the composite due to the direct magnetoelectric effect. Conversely,...journal article 2009

(author)Photo- and thermoluminescence (TL) spectra of NaLaF4:Ln3+ (Ln = Ce,Pr,Nd,Sm,Eu,Gd,Tb,Dy,Ho,Er,Tm) and NaLaF4:Ce3+, Ln3+ (Ln = Nd,Sm,Ho,Er,Tm) are presented and used together with the empirical Dorenbos model in order to establish the 4f energy level positions of all tri- and divalent lanthanide ions doped in NaLaF4. The information will be...journal article 2008

Dorenbos, P. (author), Van der Kolk, E. (author)Knowledge from lanthanide spectroscopy on wide band gap (6–10?eV) inorganic compounds is used to understand and predict optical and electronic properties of the lanthanides in the III-V semiconductor GaN. For the first time the location of the 4fn ground state energy of each divalent and trivalent lanthanide ion relative to the valence and...journal article 2006
