1,1-Bi(endo,exo,syn-pentacyclo[3.3.3.02,4.06,8.09,11]undecyl)[1,1-bi(trishomobarrelenyl)] (4) has been prepared as a 1:1 mixture of its meso- and d,l-diastereomers in six steps from trishomobarrelene 1 via the amine 5, the N,N-bis(trishomobarrelenyl)sulfam ...
A review. The state of the art in the detn. of structures with ultrafast electrons and x-rays is highlighted. Perspectives and reflections on the principles, techniques, and methods are provided, and on applications from different disciplines, with some fo ...
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 ...
We present a review of wave packet dynamics in different systems and stress their relation to information on the ultrafast structural changes. We show how dynamical information is obtained from ultrafast optical pump-probe studies on structural changes in ...
X-ray imaging techniques at the best spatial resolution and using synchrotron facilities are put forth as powerful techniques for the search of small life forms in extraterrestrial rocks under quarantine conditions. Absorption and fluorescence X-ray microt ...
Properties of ultra-thin films are different from their single crystal counterparts due to the presence of (substrate induced) strain, different degree and type of (growth induced) disorder and different average doping (distribution of oxygen vacancies, fo ...
We show that double-resonance spectra recorded during the simultaneous absorption of x-ray and microwave (MW) photons are a fingerprint of the perturbed electronic configuration of atomic species driven to ferromagnetic resonance. X-ray absorption measurem ...
(2,6-Dichlorophenyl)- and (2,6-dibromophenyl)trialkylsilanes undergo hydrogen/metal interconversion preferentially at the 4- rather than 3-position. However, the organometallic species generated by such a "meta metalation" are thermodynamically less stab ...
Several new results and opportunities for ultrafast x-ray absorption spectroscopy (XAS) are demonstrated. It is possible to work with highly dil. solns. in transmission mode without dramatic loss of signal-to-noise ratio. This is very promising as one can ...
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 ...
