NMR relaxometry can provide considerable information regarding the molecular dynamics in materials. When the spin-lattice relaxation (or spin-spin relaxation) is measured for a broad range of Larmor frequencies it is possible to obtain information about molecular motions in different time and length scales. Unfortunatly, that information can only be reliably obtained when it is possible to fit the most suitable relaxation models to the data. The question then is which models to use and find the best strategy to fit those models to the experimental data and, when that is achived, to evaluate how reliable the fitting parameters might be. In this tutorial some aspect of these problems will be addressed using http://fitteia.org as the data analysis and model fitting tool. Participants are invited to create an account in fitteia.org and explore the environment [1,2] [1] The art of model fitting to experimental results", P.J. Sebastião, Eur. J.

The word diffusion derives from the Latin word diffundere, which means "to spread out". In the most general case, diffusion is a phenomenon that refers to the net movement of an object driven by a gradient of some magnitude factor. The process has a stochastic nature, and its concept plays an important role in many areas of physics, chemistry, biology, sociology, economics, and finance, constituting a broad field for research. In natural sciences, diffusion is not limited to a given state of matter but can occur in solids, liquids, and gases. It conditions the life processes by determining the transport through membranes, cells eventually, the whole body. In chemical processes, it is often the central rule driving many reactions. In physics, it defines many transport processes for atoms, ions, or molecules. A distinguishing feature of diffusion is that it depends on particle random walk and results in mixing or mass transport without requiring directed bulk motion. The first description of the diffusion phenomena was given by Adolf Fick in 1855. Fick's laws can be used to solve for the diffusion coefficient, D. A diffusion process that obeys Fick's laws is called normal or Fickian diffusion. On the other hand, it is called anomalous diffusion or non-Fickian diffusion if the process does not follow these laws. This tutorial aims to give an overview of the wide range of applications of diffusion NMR and principles of NMR diffusometry methods that allow insight, for example, for accurate molecular size determination, in nanomedicine drug delivery, or separation of complex mixtures.

The aim of the workshop will be to introduce and explain the basics of chemical shift anisotropy. I will try to visualize the tensor formalism present in the CSA description and thus, in an intuitive way, show a direct relationship between the molecular orientation relative to the laboratory reference system and the position of the chemical shift δ in the NMR spectrum. Furthermore, we will discuss the physical significance of the shielding tensor geometry and confront it with the distribution of electronic charge density around the nucleus. Finally, I will try to explain what actually happens to shielding tensors under magic angle spinning conditions and how MAS influences and modulates effective shielding.

The tutorial aims to introduce the basics of the NMR phenomena and procedures in the MRI lab. Classes will be divided into two parts. In the first part, some basic information about NMR and MRI will be provided, and in the next step will be shown the preparation of an MRI research scanner, ie. tuning coil, and magnetic field shimming. Moreover, 1D NMR experiments will be carried out.The second part will show the basic experiments using Fourier imaging methods with the introduction of the spin echo imaging technique. The building of k-space during MRI experiments will be shown, to highlight the significance of Fourier transform in Magnetic Resonance Imaging. Finally, the images for the object with a well-defined structure will be obtained with spin echo and gradient echo techniques.The tutorial will be carried out with the use of ICT technology and remote access to an MRI scanner at NanoBioMedical Centre in Poznan.

JASON is state of the art NMR processing software from JEOL and fully vendor agnostic. Data from all vendors can be analysed in JASON, with tools including integration, multiplet analysis, assignment and for more advanced experiments such as relaxation and diffusion measurements. In this session I will cover how to use JASON to process and analyse NMR experiments along with producing reports. Moreover, JASON will organize a 3-month JASON coupons (for JASON Software) fot the attendees to access JASON before the conference which will be send to all participants.

Design Sprint (DS) is a methodology for quick and effective problem solving in design. It draws on design thinking, i.e. creative designing solutions to problems, products and services, as well as other practical methods used in business. Now, it is our wish to apply the DS approach also in science to make researchers more attentive to end-users’ needs at the earliest stages of materials and products design before production. The DS process includes five following stages that use design thinking to reduce risk and negative consequences of bringing a new product and service to the market. First of all, we need to understand (define the goal of the project), then outline new ideas, decide on the best solution, prototype (raw version of the project) and test, that means collecting opinions to specify further works on the product. The DS allows for a fast and cheap prototyping of ideas and their subsequent implementation. Therefore, this workshop is dedicated to scientists whose research cover all levels of the Technology Readiness Levels (TRLs) starting from observations of basing principles (basic research levels TRL1 - TRL3) by technology validation in relevant environments (TRL4 – TRL6) to demonstrators of prototypes (TRL7 – TRL9). During our Workshop, to address such challenges of binding basic scientists with researchers who work at higher TRLs levels under real products, we will build multidisciplinary teams. The end-user approach will allow us to study real needs and visualize particular solutions and final products that we all may use every day. An example of such a project may be finding an environmentally friendly heating system to heat up a flat in a tenement house located in the old town of our city. For that, participants of the workshop will collect interviews with a so called “persona” (a hypothetical inhabitant) including all necessary knowledge about their preferences, financial status, etc. To support participants of our process with real world solutions, we will also focus on studies of real cases like the evolution of end-users that happened during design and construction works of the NANOTOOL – a sensor for nanoparticles detection coming from the air.
