Molecular assembly of the aerolysin pore reveals a swirling membrane-insertion mechanism

Henning Paul-Julius Stahlberg, Françoise Gisou van der Goot Grunberg, Matteo Dal Peraro, Matteo Thomas Degiacomi

Aerolysin is the founding member of a superfamily of (beta-pore-forming toxins whose pore structure is unknown. We have combined X-ray crystallography, cryo-EM, molecular dynamics and computational modeling to determine the structures of aerolysin mutants ...

Synthesis, Molecular Structure and Cytotoxicity of Molecular Materials Based on Water Soluble Half-Sandwich Rh(III) and Ir(III) Tetranuclear Metalla-Cycles

Paul Joseph Dyson, Benjamin Samuel Murray

The neutral dinuclear complexes [(eta(5)-C5Me5)(2)Rh-2(mu-dhnq)Cl-2] (1) and [(eta(5)-C5Me5)(2)Ir-2(mu-dhnq)Cl-2] (2) (dhnqH(2) = 5,8-dihydroxy-1,4-naphthoquinone) were obtained from the reaction of (eta(5)-C5Me5)M(mu-Cl)Cl (M = Rh, Ir) with dhnqH(2) ...

Synthesis, characterization and X-ray crystal structures of two polymorphs of a cobalt(III) complex with a N3O2 pentadentate Schiff base ligand, and benzylamine: spectral and electrochemical studies

Kurt Schenk

The title complex [Co-III{(naph)(2)dpt}(bzlan)]BPh4, where (naph)(2)dpt stands for bis-(2-hydroxy-1-naphthaldimine)-N-dipropylenetriamine dianion and bzlan for benzylamine, has been synthesized and characterized by elemental analyses, IR, UV-Vis and H-1 NM ...

Fast iterative reconstruction of differential phase contrast X-ray tomograms

Michaël Unser, Cédric René Jean Vonesch, Peter Modregger, Masih Nilchian, Marco Stampanoni

Differential phase-contrast is a recent technique in the context of X-ray imaging. In order to reduce the specimen's exposure time, we propose a new iterative algorithm that can achieve the same quality as FBP-type methods, while using substantially fewer ...

Design of T-GEM detectors for X-ray diagnostics on JET

Patrick Blanchard

Upgraded high-resolution X-ray diagnostics on JET is expected to monitor the plasma radiation emitted by W46+ and Ni26+ ions at 2.4 keV and 7.8 keV photon energies, respectively. Both X-ray lines will be monitored by new generation energy-resolved micropat ...

Phase Retrieval for Sparse Signals: Uniqueness Conditions

Martin Vetterli, Yue Lu, Juri Ranieri, Amina Chebira

In a variety of fields, in particular those involving imaging and optics, we often measure signals whose phase is missing or has been irremediably distorted. Phase retrieval attempts the recovery of the phase information of a signal from the magnitude of i ...

Soft tissue artifact assessment during treadmill walking in subjects with total knee arthroplasty

Jean-Philippe Thiran, Kamiar Aminian, Arnaud Barré

Accurate measurement of knee kinematics during functional activities suffers mainly from soft tissue artifact (STA): the combination of local surface deformations and rigid movement of markers relative to the underlying bone (also called rigid STA movement ...

Studies on the Effect of Strain on the Electronic Properties of Ultra Thin Films of Superconducting Cuprates

Nathaniel Wooding

High Tc superconductivity in cuprates is still an unresolved topic, and one particular challenge is why in-plane compressive strain enhances Tc in ultra thin LSCO-214 films (< 40nm), whilst tensile strain diminishes it. Especially intriguing is whether alt ...

A sensitive x-ray phase contrast technique for rapid imaging using a single phase grid analyzer

Peter Modregger, Simon Rutishauser, Christian David, Marco Stampanoni

Phase contrast x-ray imaging (PCXI) is a promising imaging modality, capable of sensitively differentiating soft tissue structures at high spatial resolution. However, high sensitivity often comes at the cost of a long exposure time or multiple exposures p ...

Lanthanide Complexes Based on beta-Diketonates and a Tetradentate Chromophore Highly Luminescent as Powders and in Polymers

Marinella Mazzanti

A new type of octacoordinated ternary β-diketonates complexes of terbium and europium has been prepared using the anionic tetradentate terpyridine-carboxylate ligand (L) as a sensitizer of lanthanide luminescence in combination with two β-diketonates ligan ...
