Giant supramolecules as molecular containers European Crystallographic Meeting 2019, ECM 2019, ViennaVienna, Austria, 18 Aug 2019 - 23 Aug 2019   One of the most outstanding areas in the modern coordination chemistry is the rational design of giantsupramolecules built up from metal ions connected to each other via polytopic ligands resulting in large hollowcages. The systematic approach to the synthesis of hollow supramolecules developed in our group is thecoordination of Cu+ and Ag+ cations to phosphorus atoms of the pentaphosphaferrocenes, [CpRFe(hapta5-P5)] (CpR=hapta5-C5R5, R=Me (Cp*), CH2Ph (CpBn), etc.) [1-3].

Phosphorus can do more: $\pi–\pi$ stacking of planar aromatic P5-rings European Crystallographic Meeting 2019, ECM 2019, ViennaVienna, Austria, 18 Aug 2019 - 23 Aug 2019   The directed non-bonding interactions play an important role in modern supramolecular chemistry. Concerningphosphorus, so-called pnictogen bonding is usually mentioned in this context [1] [...] External link: Fulltext 2020-08-0417:30 [PUBDB-2020-02933] Abstract Altomare, M. ; Spanu, D. ; Recchia, S. ; et al Dewetting-Alloying of Nicu Bilayers on $TiO_{2}$ Surfaces for Noble Metal-Free Photocatalytic $H_{2}$ Evolution 237th Electrochemical Society (ECS) Meeting, MontrealMontreal, Canada, 10 May 2020 - 14 May 2020   We present an approach to fabricate an efficient noble metal-free photocatalytic platform for H2 evolution and provide evidences that the photocatalyst active state forms via a photo-induced redox process in organic-water mixtures.To fabricate the photocatalytic platform, NiCu bilayers (thickness in the range of a few nm) are deposited by Ar-plasma sputtering on anodic TiO2 nanocavity arrays.[1] A subsequent thermal treatment triggers solid-state dewetting[2,3] of the metal bilayer, i.e. owing to surface diffusion, the Ni and Cu films agglomerate and inter-mix forming NiCu bimetallic nanoparticles at the TiO2 surface.[4] This approach allows for a full control over key features of the NiCu nanoparticles, e.g. [...] External link: Fulltext 2019-12-1214:29 [PUBDB-2019-05105] Abstract Peruzzi, N. ; Bech, M. ; Dahlin, L. ; et al Evaluation of the enteric nervous system by three-dimensional holographic imaging in x-ray phase contrast nanotomography UEG Week, BarcelonaBarcelona, Spain, 21 Oct 2019 - 23 Oct 2019   IntroductionThe enteric nervous system (ENS) in dysmotility has been studied by classical light microscopy including immunohistochemistry. However, the procedure is rather time-consuming and only small components of the ENS in two dimensions can be analyzed.

It displays a high specific surface area, high electrical conductivity and good mechanical properties, making it very interesting for sensing and actuating applications [1].

Due to their high geological relevance, numerous X-ray diffraction studies at non-ambient conditions (high temperature (HT) and / or pressure (HP)) have been performed with detailed studies focused on orthoclase, sanidine, microcline, albite, and anorthite.

Influence of anchoring ligands on electronic and magnetic properties of heterobimetallic complexes 17th International Conference on X-ray Absorption Fine Structure, XAFS 2018, KrakowKrakow, Poland, 22 Jul 2018 - 27 Jul 2018   Magnetic molecules are envisaged as functional units in the molecular and supramolecular spintronic devices for future information technology. An essential first step in the implementation of the molecular systems in devices is the study and control of the molecule-electrode interfaces.

E. ; et al Structural investigations of spider attachment hairs Verhandlungen der Deutschen Physikalischen Gesellschaft e.V., BerlinBerlin, Germany, 11 Mar 2018 - 16 Mar 2018   The hairy attachment system of spiders enables these animals to walkupside-down on rough and smooth surfaces without the use of glue.These outstanding biological structures comprise of pads includinghundreds to thousands of specially designed hairs that are made ofcomposite materials consisting of proteins and reinforcing chitin fibres.The goal of our study is to gain an in-depth understanding of thestructure-function mechanism of the attachment and detachment processesof single hairs to a surface. X-ray Tomographic Microscopy andScanning X-ray nanobeam diffraction are ideal tools to reveal the innerstructure of the spider hairs and allow to determine the gradient of themechanical properties which is essential for the attachment process.With both techniques we found that the shaft of the attachment hairis hollow.
