Journal ArticleDOI
UV-induced functionalization of poly(divinylbenzene) nanoparticles via efficient [2 + 2]-photocycloadditions
Anitha Ethirajan,Linny Baeten,Matthias Conradi,Kayte Ranieri,Bert Conings,Hans-Gerd Boyen,Thomas Junkers +6 more
TL;DR: In this article, the efficient functionalization of poly(divinylbenzene) (polyDVB) nanoparticles via Paterno-Buchi type [2 + 2]-photocycloadditions is described.
Journal ArticleDOI
Characterization of ultrathin insulating Al2O3 films grown on Nb(110)/sapphire(0001) by tunneling spectroscopy and microscopy
TL;DR: In this article, the structural and chemical properties of ultrathin Al2O3 films on Nb(110)/sapphire (0001) were analyzed. And the results showed that the niobium film underneath is completely protected from oxidation.
Journal ArticleDOI
Growth mechanism for epitaxial cubic boron nitride films on diamond substrates by ion beam assisted deposition
TL;DR: In this article, the plasmon energies of the diamond substrates that were held at various temperatures and bombarded by a mixture of argon and nitrogen ions were determined from in situ low-energy electron energy loss spectra.
Journal ArticleDOI
Low-temperature interface reactions in layered Au/Sb films: In situ investigation of the formation of an amorphous phase.
Hans-Gerd Boyen,A. Cossy-Favre,Peter Oelhafen,A. Siber,Paul J. Ziemann,C. Lauinger,T. Moser,Peter Häussler,F. Baumann +8 more
TL;DR: Photoelectron-spectroscopy methods combined with electrical-resistance measurements were employed to study the effects of intermixing at Au/Sb interfaces at low temperatures, finding evidence that for multilayers with large modulation lengths containing unreacted polycrystalline Au and Sb layers, long-range interdiffusion is found to set in at temperatures above 230 K.
Journal ArticleDOI
Electron energy loss spectroscopy—An additional tool to characterize thin films of cubic boron nitride
TL;DR: In this paper, the authors used Reflection Electron Energy Loss Spectroscopy (REELS) to characterize boron nitride (BN) films with various contents of the cubic phase (0, 95%) as determined by infra-red (IR)-spectroscopy.
