Daniel G. Nocera is the Patterson Rockwood Professor of Energy at Harvard University. He is widely recognized in the world as a leading researcher in renewable energy. His group has pioneered studies of the basic mechanisms of energy conversion in biology and chemistry with a particular focus on multielectron transformations and the coupling of protons to electron transfer (i.e., proton-coupled electron transfer). A recent focus in the group has been to exploit this mechanistic knowledge for the generation of solar fuels.He has accomplished the solar process of photosynthesis – the splitting of water to hydrogen and oxygen using light from neutral water, at atmospheric pressure and room temperature at efficiencies of greater than 10%. This discovery, called artificial leaf, was named by Time magazine as Innovation of the Year for 2011. He has since elaborated this invention to accomplish a complete artificial photosynthetic cycle. To do so, he created the bionic leaf, which is a bio-engineered bacterium that uses the hydrogen from that artificial leaf and carbon dioxide from air to make biomass and liquid fuels. The bionic leaf, which was named by the World Economic Forum as the Breakthrough Technology for 2017, performs an artificial photosynthesis that is ten times more efficient than natural photosynthesis. Extending this approach, Nocera has achieved a renewable and distributed synthesis of ammonia (and fertilizer) at ambient conditions by coupling solar-based water splitting to a nitrogen fixing bioorganism, which is powered by the hydrogen produced from water splitting. These science discoveries set the stage for a storage mechanism for the large scale, distributed, deployment of solar energy and distributed food production and thus are particularly useful to the poor of the world, where large infrastructures for fuel and food production are not tenable.Other areas of interest in the group include the development of proton-coupled electron transfer and its application to radical enzymology, the development of new cancer therapies by creating nanocrystal chemosensors for metabolic tumor profiling, the creation of spin frustrated materials, which has culminated in the discovery of the quantum spin liquid, and the invention of molecular tagging velocimetry technique for the measurement of highly turbulent fluid flows.

Two-dimensional (2D) layered semiconductors are at the forefront of scientific and technological interest. The research on layered compounds is thriving since the eighties of the previous century, due to their extraordinary electronic, photonic, optical, and mechanical properties. At that time, 2D semiconductors mainly included naturally grown lamellar crystals and synthetically grown materials. The recent renaissance of the field of 2D compounds was triggered by the discovery of graphene, as well as a myriad of inorganic compounds, like single-layer transition-metal di-chalcogenides and black phosphorous, all prepared via exfoliation or CVD techniques. Above all, solution-based "bottom-up" colloidal chemical methods emerged most recently, offering appealing new pathways for honeycomb super-structures exhibiting linear Dirac-type band dispersions.
The nanoGe2019 conference will bring together academic and industrial scientists from closely related 2D materials communities to exchange knowledge and ideas about preparation methodologies and about unique physical properties, including topological insulators, Dirac-type electronic band structure, spin-valley coupling, quantum spin Hall effect, magnetism, symmetry breaking, layer-layer or layer-substrate interactions, influence of geometry and curvature, effect of electronic many-body interactions, and other related topics. The discussions will cover also unique methodologies for exploring the physical properties and theoretical modeling of the physical phenomena. There is a promising perspective to implement 2D semiconductors in a variety of technologies including spintronic devices, field-effect transistors, nanoscale sensors, batteries, photodetectors, LEDs, which can be leveraged via stimulating meetings of the kind proposed here.

Single-junction photovoltaic devices only convert a narrow fraction of the solar spectrum
efficiently. Up- and down-conversion have long been proposed as a route towards improved
performance, and excitonic materials are emerging as a realistic path towards this goal.
Significant challenges remain; from the fundamental understanding of excitonic conversion
processes and energy transfer across interfaces, to the development of improved organic
materials for singlet fission and triplet-triplet annihilation, efficient infrared photon emitters, and device architectures.
This symposium will bring together experts from the field of excitonic up- and downconversion
to discuss this interdisciplinary topic with a clear focus on the understanding of
excitonic processes and device integration.
- Fundamentals of singlet fission
- Multi-exciton interactions in nanocrystals and other low-dimensional materials
- Spin-dependent exciton dynamics in nanomaterials
- Theoretical treatments of excitonic conversion and energy transfer
- Multi-photon schemes for solar fuel generation
- Understanding and controlling triplet transport and annihilation for upconversion
- Novel organic and inorganic materials for up-conversion and singlet fission
- Device implementations for photovoltaics, solar fuels, and photon detection.

Engineering optoelectronic devices based on nanostructured materials requires understanding charge carrier dynamics at the nanoscale. Fundamental processes such as the generation and nature of excitons, their fission into free charge carriers, carrier migration and recombination depend strongly on the structural, electronic and magnetic properties of the nanomaterial. The surface chemistry of nanostructures, in particular the interface between a hard crystalline core and a soft molecular shell, profoundly affects the local electronic structure of the material. Synthesizing nanosystems with long-range structural order offers the prospect of influencing the electronic structure on a macroscopic level and creating new device functionalities.
This symposium aims at deepening the understanding of the correlation between the above-mentioned effects with device performance by bringing together experts from different disciplines such as solid-state chemistry and physics, spectroscopy, device physics, scattering, computational physics/chemistry, microscopy, soft matter and surface science. A particular aim of the meeting is to give an overview of the state-of-the-art of characterization techniques available to analyze nanomaterials in this context. This is intended to serve as valuable tools to excel in designing better optoelectronic devices based on nanomaterials in the future.

This symposium will cover the interplay between the structural features of halide perovskites and the physical
processes determining their optoelectronic performance. The discussion on the lattice role will include electrical and
optical ultrafast spectroscopic techniques (such as transient absorption, impedance, capacitance and
photoluminescence) to monitor the carrier dynamics, carrier-phonon interactions, exciton dynamics, polaron
formation etc. These will be related to the direct observation of perovskite’ structural characteristics in the
nanometric scale, as well as to the results obtained by other structural analysis tools such as Raman and IR
spectroscopies among others. These results will be complemented by modelling works discussing the nature of the
charge within the material, including the theoretical calculations to the discussion. Advances on the understanding of
these mechanisms will be key to exploit the full potential of perovskites, and design the most efficient light emitting
diodes, solar cells and lasers. The viability of further halide perovskites applications, such as hot-carrier, multiband
or multiple exciton generation photovoltaics, will be subject to the structure interactions as well, through processes
such as carrier scattering and thermalization.

Scanning probe microscopy (SPM) methods have become indispensable for studying and understanding the underlying mechanisms in functional nanostructures. This is largely due to the flexibility and versatility of the available imaging modes. This way, surface topography can be correlated with a large number of additional local surface properties, such as surface potential via Kelvin Probe force microscopy, or even chemical information, e.g. via locally recorded infrared spectra. Recently, the implementation of fast imaging methods and pump-probe type measurement schemes have enabled the study of fast and even ultra-fast dynamics in nanostructures.
In this symposium, we want to discuss recent advances in the instrumentation and the available imaging modes, as well as in the application of these modes to functional nanostructures. A particular shall be on the investigation of electrical and optoelectronic functionalities, such as photovoltaic, (photo-)electrochemical, biological and ferroic materials, and related phenomena such as ion dynamics, charge separation etc. In addition, we want to discuss the latest advances and applications in optical SPM modes, such as TERS, Nano-IR, PIFM, etc.

X-ray detection for medical imaging relies upon high sensitivity materials as a primary concern. Enhancing the sensitivity of X-ray detectors minimizes the X-ray dose during routine medical examinations. Despite tremendous investment in inorganic detectors, technical requirements limit their applicability. Therefore, there is need for reconfigurable soft materials compatible with facile integration. Sensitive and low-cost X-ray detectors have been actively sought. Recently, it’s been shown that the lowest detectable X-ray dose rate using single crystals of CH3NH3PbBr3 perovskite is 0.5 μGyair s–1 which is much lower than that required for regular medical diagnostics (5.5 μGyair s–1) and with a sensitivity 80 μC G cm–2 higher that current state of the art Se X-ray detectors. Perovskite materials combine unique features that might empower breakthrough detector technology for broad applications in the fields of security, defense, medical imaging, diagnostics, astrophysics, industrial material inspection, nuclear power stations and scientific research. In this symposium, we aim to bring key elements required to pave the way to cheaper and low does high-energy radiation detectors and scintillators.
