The first annotated set of scanning electron microscopy images for nanoscience
Read Abstract
In this paper, we present the first publicly available human-annotated dataset of images obtained by the Scanning Electron Microscopy (SEM). A total of roughly 26,000 SEM images at the nanoscale are classified into 10 categories to form 4 labeled training sets, suited for image recognition tasks. The selected categories span the range of 0D objects such as particles, 1D nanowires and fibres, 2D films and coated surfaces as well as patterned surfaces, and 3D structures such as microelectromechanical system (MEMS) devices and pillars. Additional categories such as tips and biological are also included to expand the spectrum of possible images. A preliminary degree of hierarchy is introduced, by creating a subtree structure for the categories and populating them with the available images, wherever possible.

Laser ablation and injection moulding as techniques for producing micro channels compatible with Small Angle X-Ray Scattering
Read Abstract
Microfluidic mixing is an important means for in-situ sample preparation and handling while Small Angle X-Ray Scattering (SAXS) is a proven tool for characterising (macro-)molecular structures. In combination those two techniques enable investigations of fast reactions with high time resolution (<1 ms). The goal of combining a micro mixer with SAXS, however, puts constraints on the materials and production methods used in the device fabrication. The measurement channel of the mixer needs good X-ray transparency and a low scattering background. While both depend on the material used, the requirement for low scattering especially limits the techniques suitable for producing the mixer, as the fabrication process can induce molecular orientations and stresses that can adversely influence the scattering signal.

Nano-confinement of block copolymers in high accuracy topographical guiding patterns: modelling the emergence of defectivity due to incommensurability
Read Abstract
Extreme ultraviolet interference lithography (EUV-IL) is used to manufacture topographical guiding patterns to direct the self-assembly of block copolymers. High-accuracy silicon oxide-like patterns with trenches ranging from 68 nm to 117 nm width are fabricated by exposing a hydrogen silsesquioxane (HSQ) resist layer using EUV-IL. We investigate how the accuracy, the low line width roughness and the low line edge roughness of the resulting patterns allow achieving DSA line/space patterns of a PS-b-PMMA (polystyrene-block-poly methyl methacrylate) block copolymer of 11 nm half-pitch with low defectivity. We conduct an in-depth study of the dependence of the DSA pattern morphology on the trench width and on how the neutral brush covers the guiding pattern. We identify the relation between trench width and the emergence of defects with nanometer precision. Based on these studies, we develop a model that extends available free energy models, which allows us to predict the patterning process window.

WP11 - NA – Innovation and networking activities
D11.8 - Operational marketing plan towards industry
Read Abstract
Industrial innovation and knowledge transfer by exploiting the NFFA-Europe facilities are common objectives that the Technical and the Industrial Liaison Networks (TLNet/ILNet) set out jointly to achieve through six primary tasks in the 2017-2018 period. Two of these tasks answer back the actual needs of increasing both the industrial participation in the feasibility studies as well as the success rate in the number of granted access. The strategies enacted by NFFA-Europe in reaching out towards industry are described in the Operational Marketing Plan which is divided into two main sections.

D11.12 - First Report on the incentivised knowledge transfer and feasibility work with industry
Read Abstract
This first report on the incentivised knowledge transfer and feasibility work with industry aims at describing the work carried out by the Technical Liaison Network to raise more awareness on the feasibility studies and on the next steps to upgrade the portal to harvest industrial requests. A survey on feasibility studies in the NFFA-Europe offer has highlighted a temporary under-exploitation of this tool by potential industrial users.

D11.10 - Educational videos
Read Abstract
NFFA-Europe is a Research and Innovation Action committed to providing free access to state-of-the art tools for multidisciplinary, frontier research at the nanoscale: available techniques range from nano-characterisation to theory and numerical simulation. With the aim to enhance the knowledge in the nanoscale area for the European research community, this deliverable explains the action towards obtaining some educational materials freely available through the web-site. This material is based on the edition of a set of short-duration Educational Videos. The videos are being designed by expert scientists in the field and edited by Promoscience. Fifteen videos have been established to cover most of the NFFA-Europe techniques: 6 videos deal with lithography techniques, 2 videos deal with chemical and physical materials growth, 2 videos deal with theory and simulation techniques and finally 5 videos deal with characterization techniques at the nanoscale.
