Au/TiO2 nanocomposite particles were synthesized by a method based on intense X-ray irradiation without adding any reducing agent or stabilizer. The nanocomposite exhibits promising photocatalytic and biological properties at physiologically relevant conce ...
It is shown that an elementary semi-quantitative approach explains essential features of the X-ray free-electron laser mechanism, in particular those of the gain and saturation lengths. Using mathematical methods and derivations simpler than complete theor ...
Reaction of [Ru(η6-p-cymene)Cl2]2 with two equivalents of [Ph4P][Cl] in CH2Cl2 yields [Ph4P][Ru(η6-p-cymene)Cl3], containing a trichlororuthenate(II) anion. ...

Morphology is an important factor in locomotion. It may guide the control strategies that an animal or a robot uses for efficient locomotion. In this paper we try to understand the locomotion strategies of a lizard with a distinctive feature, the long-tail ...

The sporolide quinone acid is a key fragment in the biosynthesis of the complex heptacyclic marine metabolite sporolide. We report a concise enantioselective route to this fragment, which is obtained in seven steps with 65% overall yield from trimethoxyben ...

Phase-contrast imaging at laboratory-based x-ray sources using grating interferometers has been developed over the last few years for x-ray energies of up to 28 keV. Here, we show first phase-contrast projection and tomographic images recorded at significa ...

We describe a setup for the x-ray detection of ferromagnetic resonance in the longitudinal geometry using element-specific transmission measurements. Thin magnetic film samples are placed in a static magnetic field collinear with the propagation direction ...
A new analogue high-precision peak detector is presented. Owing to its very low power consumption the circuit is particularly well suited for photon energy detection in multichannel receiver integrated circuits used in nuclear medicine. ...
A bundled electron beam (BEB) (14) is controlled regarding its excursion in its direction by two pairs of plate electrodes (17.1,17.2;18.1,18.2) that operate vertically to each other. The BEB can use appropriate control of these plate electrodes to scan an ...
