Neutron scattering has played an important role in elucidating the structure and dynamics of disordered materials, and the effect of disorder on properties.
However, neutron applications to disorder are very demanding technically, as the scattering tends to be distributed in momentum and energy space, The conference is interdisciplinary in nature, bringing together neutron scattering scientists and theorists across the traditional fields of condensed matter physics, materials science, and the soft matter.
In spite of the diversity in the materials of interest, the mechanisms underlying their intriguing physical properties could be the same or similar, and the different communities will benefit from each other through exchange of ideas and approaches. Innovative instrumentation is the backbone of scientific discoveries. One of the nine sessions will be therefore devoted to discussions of the performance of innovative instruments. In addition, there will be a session featuring industrial applications, which connects the neutron scattering community to the public.
A diverse and vibrant user community is vital for the success of the neutron scattering facilities. We thus particularly encourage the participation of young scientists, to learn and profit from interactions with leading scientists in neutron scattering in the casual environment provided by the conference.

Scientists have spent decades trying to build flexible plastic solar cells efficient enough to compete with conventional cells made of silicon. To boost performance, research groups have tried creating new plastic materials that enhance the flow of electricity through the solar cell.
Several groups expected to achieve good results by redesigning pliant polymers of plastic into orderly, silicon-like crystals, but the flow of electricity did not improve. Now Stanford University researchers have an explanation for this surprising result.

How does this work relate to the technology being developed by Nexion in the UK? Discovered nearly 40 years ago, semiconducting polymers have long been considered ideal candidates for ultrathin solar cells, light-emitting diodes and transistors.

Their findings, published in the Aug. Instead of trying to mimic the rigid structure of silicon, Salleo and his colleagues recommend that scientists learn to cope with the inherently disordered nature of plastics. In the study, the Stanford team focused on a class of organic materials known as conjugated or semiconducting polymers — chains of carbon atoms that have the properties of plastic, and the ability to absorb sunlight and conduct electricity.

Discovered nearly 40 years ago, semiconducting polymers have long been considered ideal candidates for ultrathin solar cells, light-emitting diodes and transistors. Unlike silicon crystals used in rooftop solar panels, semiconducting polymers are lightweight and can be processed at room temperature with ink-jet printers and other inexpensive techniques.
To find out why, Salleo joined Rodrigo Noriega and Jonathan Rivnay, who were Stanford graduate students at the time, in analyzing more than two decades of experimental data. It was a puzzle why these new materials worked better than the more structured crystalline ones.
The X-rays revealed a molecular structure resembling a fingerprint gone awry. Some polymers looked like amorphous strands of spaghetti, while others formed tiny crystals just a few molecules long. By analyzing light emissions from electricity flowing through the samples, the Stanford team determined that numerous small crystals were scattered throughout the material and connected by long polymer chains, like beads in a necklace. The small size of the crystals was a crucial factor in improving overall performance, Salleo said.
