Imaging on-surface hierarchical assembly of chiral supramolecular networks
Read Abstract
The bottom-up assembly of chiral structures usually relies on a cascade of molecular recognition interactions. A thorough description of these complex stereochemical mechanisms requires the capability of imaging multilevel coordination in real-time. Here we report the first direct observation of hierarchical expression of supramolecular chirality at work, for 10,10′-dibromo-9,9′-bianthryl (DBBA) on Cu(111). Molecular recognition first steers the growth of chiral organometallic chains and then leads to the formation of enantiopure islands. The structure of the networks was determined by noncontact atomic force microscopy (nc-AFM), while high-speed scanning tunnelling microscopy (STM) revealed details of the assembly mechanisms at the ms time-scale. The direct observation of the chirality transfer pathways allowed us to evaluate the enantioselectivity of the interchain coupling.

Transmission zone plates as analyzers for efficient parallel 2D RIXS-mapping
Read Abstract
We have implemented and successfully tested an off-axis transmission Fresnel zone plate as spectral analyzer for resonant inelastic X-ray scattering (RIXS). The imaging capabilities of zone plates allow for advanced two-dimensional (2D) mapping applications. By varying the photon energy along a line focus on the sample, we were able to simultaneously record the emission spectra over a range of excitation energies. Moreover, by scanning a line focus across the sample in one dimension, we efficiently recorded RIXS spectra spatially resolved in 2D, increasing the throughput by two orders of magnitude. The presented scheme opens up a variety of novel measurements and efficient, ultra-fast time resolved investigations at X-ray Free-Electron Laser sources.

Zone plates as imaging analyzers for resonant inelastic x-ray scattering
Read Abstract
We have implemented and successfully tested an off-axis transmission Fresnel zone plate as a novel type of analyzer optics for resonant inelastic x-ray scattering (RIXS). We achieved a spectral resolution of 64 meV at the nitrogen K-edge (E/dE = 6200), closely matching theoretical predictions. The fundamental advantage of transmission optics is the fact that it can provide stigmatic imaging properties. This opens up a variety of advanced RIXS configurations, such as efficient scanning RIXS, parallel detection for varying incident energy and time-resolved measurements.

D1.3 - Setup and implementation of the TA and evaluation procedures
Read Abstract
NFFA-Europe offers to European and Third Country1 scientists from both academia and industry the possibility to carry out comprehensive projects for multidisciplinary research at the nanoscale. Activities are performed in six different types of Installations: - Lithography and nano-patterning (Litho) - Growth and synthesis (Growth) - Theory and Simulation (Theory) - Structural and Morphological nano-characterisation (SM Charact.) - Electronic and Chemical nano-characterisation (EC Charact.) - Magnetic, Optical and Electric nano-characterisation (ME Charact.) Each Installation includes laboratories located in different NFFA-EU sites; furthermore, when needed, limited2 access to co-located Large-Scale Facilities for Fine Analysis is offered as part of the access to Litho, or SM, EC or ME nano-characterisation. NFFA-Europe proposals necessarily include access to more than one type of Installation (e.g. Litho and Growth, Growth and Theory, SM Charact. and EC Charact., etc.) and cannot be limited to Fine Analysis only. Whenever possible access will be granted in a single NFFA-Europe site for all research steps. Access to more than one site for a given proposal will be considered only when technically or scientifically justified.

D1.1 - Internal test of NFFA-Europe Website
Read Abstract
This deliverable describes the results achieved within task 1.5 “Communication”, and is also connected to the dissemination purposes of the project (WP11). The work done aimed at setting up the main information and functionalities of the website as a Single Entry Point (SEP) to find out about the project and access the offer of tools made available through NFFA-Europe research infrastructure.

D11.2 - Draft metadata standard for nanoscience data
Read Abstract
This document contains the NFFA Deliverable D11.2 “Draft metadata standard for nanoscience data” due in M6. It describes the approach, the relevant information management practices, standards and recommendations taken into account, as well as empirical research done by NFFA JRA3 for the purpose of metadata design, and then suggests a draft recommendation for NFFA metadata model. Having a common and well-defined metadata model is essential for human-to-human, human-to-machine and machine-to-machine interoperability in NFFA. Such a model will support the development of Information and Data management Repository Platform (IDRP) and will contribute to structured business analysis across the project. In return, the model will get further inputs from the continuing IT architecture design and business analysis. In addition to the NA activities, the deliverable has been discussed and validated through a number of conference calls and electronic communication in JRA3, as well as in the course of a dedicated face-to-face meeting in Abingdon, UK, in February 2016. The metadata model here proposed will be further validated, updated and detailed through the NFFA project activities within and beyond JRA3. It will be then finalised in D11.14 “Final metadata standard for nanoscience data” in M30. Approach
