Topic
Effects of annealing and pressure on the Grazing Incidence X-ray Scatterings of Conjugated Polymer blends used in Organic Solar Cells
Presenter:
Dr Benjamin Agyei-Tuffour, University of Ghana, GH
Summary
This presentation shows the results of an experimental study of the effects of pressure and annealing on the conjugated polymer chain configurations in poly (3-hexylthiophene) and [6,6]-phenyl C61-butyric acid methyl ester (P3HT:PCBM) blends that are used in bulk heterojunction organic photovoltaic cells (OPVs). Annealing and the application of static loads on P3HT:PCBM blends on glass substrates were investigated. Microscopy and grazing incidence x-ray scattering techniques were adopted to analyze the surface morphologies, nano-/micro-structures and the chain configurations in the conjugated polymer blends. The OPV devices fabricated resulted in the I-V characteristics that have large dependence on the changes in the nano-/ micro-structures of the polymer blends. The pressure induced polymer chain configurations that were in the direction of the applied pressure (edge-on), led to a reduced lamellae spacing between the polymer units. This increased the crystallinity in the blend and played significant role in the organic solar cell performance. The findings of the study are discussed to influence the design and control of the nano-/micro-structures and the performance of bulk heterojunction organic solar cells.

#TheLightStuff: Probing Gel Structure using Scattering â€" an Insight into Designing New Soft Materials
|
In order to be able to design new soft materials, such as gels, understanding how they form is a critical first step. Bulk measurements, like rheology, provide excellent information on their properties, but understanding their structure can be more challenging. In this talk I will show how combining small-angle X-ray and neutron scattering can give insight into gel formation and how seemingly subtle changes in the molecular chemistry of gelators can lead to sometimes unexpected new outcomes.

Further details can be found at http://bit.ly/NXSchool and http://neutrons.ornl.gov/nxs
Applications must be received by February 17th, 2020. The application process is quite competitive and requires submission of evaluation letters from the student’s advisor and two other professionals familiar with the student.
A Tribute to Isabelle Grillo: The Extraordinary Structure of Ordinary Things
| - |
In ILL, Grenoble
Isabelle Grillo dedicated her scientific life to the art of mixing surfactants, nanoparticles, polymers, emulsion droplets, as seen through the eyes of small-angle scattering. She showed that it is the most elegant method to go to the heart of colloidal interactions, by probing the intricate balance of colloidal forces, the morphology and the evolution of complex fluids.
Through the words of her closest collaborators, this symposium will highlight her outstanding contribution spanning from fundamental approaches to very practical industrially relevant questions on everyday products.
Registration and abstract submission for posters is now open. The deadline for abstract submission is 23 February 2020.Â

Neutrons for membrane biophysics
| - |
In Garching (near Munich)
The organised school will be an international meeting with contributions from leading neutron scattering and deuteration facilities. Together with contributions by academic researchers there is a great potential impact for neutron scattering over a diverse range of scientific problems. We will focus on the three experimental techniques (neutron reflectivity, neutron lamellar diffraction and small angle neutron scattering) and the structural perspective that these techniquesgive on the arrangements of lipids into bilayers, the solubilisation of small molecules and interactions of larger biomolecules with lipid bilayers.  These generic problems have wide relevance including the fields of food science, the plant sciences, biotechnology, structural biology and more general problems involving the physico-chemistry of lipid bilayers. There will be hands on experience in producing good quality samples and the measurement and analysis of data on world class neutron instrumentation.  Deuteration is an indispensable adjunct to the structural perspective of neutron scattering which allows the experimentalist to highlight and resolve very specific molecular detail.  An important aspect of this workshop is to provide a context for molecular deuteration from experts, well versed in the power, and importantly the limitations of the technique.Â
Additionally we will give instruction, and provide software for, traditional methods of data analysis, modelling of SANS and reflectivity data, and unit cell reconstructions of diffraction data. We will also examine the possibilities in the use of molecular dynamics simulations for direct comparison with scattering derived models.
