Breakout symposia will be held on Friday, August 18, in morning and afternoon sessions. Contributed talks will be accepted for most symposia. The number of contributed talks to be accepted for each session follows the descriptions below. Submit a symposium abstract here for both contributed and invited talks. The abstract submission deadline to be considered for a contributed symposium talk is June 25, 2017.

New quantum materials are emerging that feature unprecedented capabilities. Of particular note are the low-dimensional materials, like graphene, widely cited as a wonder material for the future. Such "quantum" materials present new properties because of carrier confinement in their ultrathin and ultraflat structures. Notably, more complex material systems are emerging that are more device-ready than graphene, such as the transition metal dichalcogenides. The idea of designing such material systems is straightforward: it is possible to imagine a novel material and work out its synthesis and properties, but synthetically accessible compounds that aren’t ordered by analogy to to known material systems might be missed. We aim to understand nonequilibium process of materials synthesis in a joint session linking theory and synthesis focusing on the complex processes leading to a multicomponent materials, like a binary crystal, hybrid materials, and compounds with compositional degrees of freedom. New approaches to unifying the ideas of materials by design with synthesis by design will be explored in the context of the very thin, fast, and fascinating low-dimensional material systems.

Sustainable generation of commodity chemicals through interfacing living and non-living structures has the potential to combine the strengths of biological and inorganic systems. Specifically, inspired by natural photosynthesis, harnessing electron transfer from semiconductor light absorber to specialized bacteria may offer a unique way to achieve high efficiency and selectivity in otherwise complex energy relevant processes, such as conversion of CO2 and N2 to reduced products. This workshop aims at presenting the state-of-the-art of current biohybrid architectures in the field of energy storage and solar-to-chemicals conversion, and discussing feasibility of these approaches in next generation energy materials.

Assemblies of nano-particles and even bulk materials that contain a rich variety of defects, interfaces and surfaces commonly exhibit unique material properties because their atom configurations are not strictly bulk-like. Instead, bond configurations and their strength vary locally which greatly alters threshold values for atom displacements. Catalytic reactions, vacancy driven diffusion processes in device structures or conformational molecule changes may serve as examples.
This workshop summarizes the current state of the art "gentle" TEM imaging including addressing the existing dose gap between required electron dose to image single atoms and the maximum dose that can be tolerated before structural object alterations occur; and current approaches to track functional behavior at atomic resolution. It will highlight the utilization of dose rates and time resolution to bridge the dose gap and perform time dependent investigations that allow observing pristine object structures as well as beam-induced excitations that provide physically relevant information. Guidelines to perform optimized experiments will be obtained by providing a platform to discussing advantages and limitations of the current techniques.

New developments in microscopy and spectroscopy techniques lead to enormous datasets, far larger than an individual can practically analyze. These developments include hyperspectral imaging, correlative microscopies, and in-situ experiments operating from video rate to ultrafast speeds. The primary challenge is converting this vast volume of data into information, allowing users to interpret their experiments and gain insights that were previously unobtainable. In this symposium, speakers will describe their approaches to analyzing large datasets and how these experiments have transformed their research. We will also discuss existing and future challenges as big data methods become commonplace, especially the needs of the Foundry user community.

The design and study of advanced nanosystems presents extraordinary opportunities for engineering architectures to achieve precision control of information storage, amplification, and transport. Importantly, these systems hold promise to advance the fundamental study of disorder and topology in the solid state alongside our understanding of quantum coherence.
To realize this potential, programming and testing targeted interactions within individual nanostructures and their higher-order assemblies under relevant perturbations will be necessary. Integrative efforts will be required to engineer multi-component systems which bridge best-in-class capabilities of both top-down fabrication and colloidal synthesis. Precise, correlative measurements at high spatial and temporal resolution will need to be leveraged to probe defects and for testing protocols which have been advanced by theory. To explore these themes, this symposium will focus on quantum architectures and realizable experiments with nanoscale components.

Soft materials are characterized by their multiple, weak interactions, which allow for higher order assemblies and properties that can be tailored to specific functions such as binding or catalysis. However, designing, synthesizing, and characterizing these materials has been difficult. This symposium will highlight the work at the Molecular Foundry in the design and building of soft materials as well as the development of analytical and imaging techniques for these materials.

An emerging area of interest in the Foundry’s User Community is responsive and reconfigurable materials, where physical or chemical stimuli are able to transform a material structurally or chemically and thereby alter its properties. Such transformations might include rearrangements in molecular packing, phase transitions in condensed matter (both hard and soft), or guest-directed chemical conversion. Triggered transformations in a material often give rise to useful macroscopic behaviors that are not initially observed. As a result, this class of materials makes available new opportunities for advancing clean energy technologies, including smarter materials for sensors, chemical separations, energy storage devices, etc. This symposium will explore the foundations being laid at the Foundry to develop the science of reconfigurable materials, linking dynamic structure-property relationships across relevant length and time scales in both materials and devices incorporating them.

This symposium will cover emerging techniques and methods to probe dynamic phenomena in heterogeneous nanomaterials. The topics will span mature techniques such as in situ electron microscopy and emerging techniques such as ultrafast characterization with photons and electrons using small probes. The aim is to discuss the wide variety of methods that can be used to probe dynamic phenomena, including both "pump-probe" techniques and "single-shot" techniques. In addition, we anticipate discussing new types of nanoscale imaging techniques that can be used, such as scanning nanodiffraction or ptychography.
