Triphilic block copolymers made of a hydrophilic block and two mutually immiscible hydrophobic blocks, namely of a lipophilic and a fluorophilic one, self-assemble into multicompartment micelles. The separate nanodomains are visualized by cryo-TEM. They can selectively solubilize lipophilic and fluorophilic molecules, respectively, while hydrophilic molecules stay in the aqueous phase. © 2010 WILEY-VCH Verlag GmbH and Co. KGaA. Source

The ANTARES telescope is well-suited for detecting astrophysical transient neutrino sources as it can observe a full hemisphere of the sky at all times with a high duty cycle. The background due to atmospheric particles can be drastically reduced, and the point-source sensitivity improved, by selecting a narrow time window around possible neutrino production periods. Blazars, being radio-loud active galactic nuclei with their jets pointing almost directly towards the observer, are particularly attractive potential neutrino point sources, since they are among the most likely sources of the very high-energy cosmic rays. Neutrinos and gamma rays may be produced in hadronic interactions with the surrounding medium. Moreover, blazars generally show high time variability in their light curves at different wavelengths and on various time scales. This paper presents a time-dependent analysis applied to a selection of flaring gamma-ray blazars observed by the FERMI/LAT experiment and by TeV Cherenkov telescopes using five years of ANTARES data taken from 2008 to 2012. The results are compatible with fluctuations of the background. Upper limits on the neutrino fluence have been produced and compared to the measured gamma-ray spectral energy distribution. © 2015 IOP Publishing Ltd and Sissa Medialab srl . Source

A new soluble In+ source containing the very weakly coordinating anion [Al{OC(CF3)3}4]- was developed. In reaction with a P2 ligand complex an unprecedented tetracationic aggregate is formed featuring a short In···In distance (see picture). Polymeric strands arising from a reaction with a cyclo-P3 ligand complex exhibit a novel coordination mode for P 3 units. © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Source
