The crystallisation phase transformation process and the resulting creation of crystalline materials from liquid phase precursors are central to the science and process engineering of materials in their broadest sense. Crystallisation involves two distinct stages: nucleation and growth. Due to the nano-scale size domain within which the nucleation process functions it is a much less understood process compared to the growth process. As a result, elucidating the fundamental physics and chemistry that govern the formation and structure of the nucleation supra-molecular transition state remains one of the truly unresolved 'grand challenges' of the physical sciences. Following the Nucleation - A Transition State to the Directed Assembly of Materials: Faraday Discussion (April 2015), this book brings together the growing body of theoretical and experimental work. It assesses recent progress in this field, highlights on-going challenges, and discusses future work still needed.

The last ten years have seen a revolution in our understanding of the mechanisms of biological crystal growth. While it had long been assumed that crystallisation would occur by the same classical mechanisms which form the basis for most descriptions of crystallisation processes, it is now becoming apparent that this is not the case. There are a number of key observations which have changed our view of crystallisation mechanisms. While it had long been assumed that crystalline biominerals typically form by ion-by-ion growth, it is now recognised that they often precipitate via amorphous precursor phases. This is well established for calcium carbonate and there is growing evidence that biogenic crystalline calcium phosphate phases may form via an analogous route. Recent re-examination of the structure of many calcium carbonate biominerals is also suggesting that "non-classical" crystallisation pathways, where crystals grow from the assembly of precursor particles, may also be widespread. Significantly, these mechanisms are not unique to the biological world. Possibly partly inspired by the identification of these biogenic mineralisation strategies, there is currently great interest from the general crystal growth community in these new and controversial ideas. A number of studies on crystal nucleation have recently re-examined classical nucleation theory, and the observation of pre-nucleation clusters is a recurrent theme of great interest. This controversial result apparently contradicts classical nucleation theory which leads the subject of crystal nucleation and growth via assembly to demand attention. The Scientific Committee warmly invites you to take part in this thought-provoking Discussion and looks forward to welcoming you to Leeds.

There has been exponential growth in the number of nanoporous framework materials reported in the scientific literature over recent years, with thousands of new metal–organic frameworks (MOFs), covalent organic frameworks (COFs), molecular framework materials, inorganic framework materials, and supramolecular frameworks. These novel families of materials open up new horizons in practically all branches of engineering, physics, chemistry, biology, and medicine. Many framework materials are based on relatively weak interactions (coordinative bonds, π−π stacking, hydrogen bonds, etc.), and present large numbers of intramolecular degrees of freedom. Evidence is accumulating that there is a propensity among these framework materials to display large-scale dynamic behaviour. These cooperative phenomena are very diverse both in terms of their microscopic origins and their macroscopic manifestations. This volume brings together internationally leading researchers to identify the open questions and challenges in this field as well as the best ways to address them.

Silicon is the most important semiconducting material of the microelectronic industry. Bulk silicon does not exhibit good optical properties, however in the late 1980s good emission was observed and studied in a silicon-based material, porous silicon. Since then, a variety of luminescent silicon nanostructures have been investigated, but different results and interpretations have been reported in the literature regarding the origin of the luminescence of these structures. This Faraday Discussion explores new methodologies to synthesize and characterise luminescent silicon nanostructures, from porous silicon to nanocrystals and nanorods. Attention is devoted to the most promising applications of these systems in the fields of bioimaging, sensing and energy conversion (e.g., OLED and luminescent solar concentrators). Wet, dry, chemical, physical, thermal, out-of-equilibrium formation paths are related to the physics of the produced nanostructures and to the role of the matrix (interface) in which they are embedded. In this volume the topics covered include: Synthesis and functionalisation of silicon nanostructures Optical and electronic properties: from theory to experiments Silicon nanostructures for sensing and bioimaging Silicon nanostructures for energy conversion devices

Over the last decade, an increasingly advanced understanding of nature’s light manipulation strategies has allowed scientists and engineers to design novel biologically inspired photonic materials for a wide range of applications. Recent research efforts have uncovered a truly astounding diversity of biological light management mechanisms that rely on various photonic structures, and there is much to be learnt from biological photonic structures for the design of advanced optical materials. Biological optical materials often create desirable synergies between quantum-optical, wave-optical, and ray-optical phenomena through a fine control of material structure and composition across all relevant length scales. Deciphering the origin of such synergies will allow scientists to emulate and improve upon them to solve challenges in optical technology development. This volume focuses on the most recent developments in this exciting and rapidly evolving field, assessing what we currently know about nature’s most intriguing light management techniques and reviewing strategies for deriving advantages from this knowledge in bio-inspired materials. More importantly, we also aim to identify current challenges and opportunities and derive a recommendation of how the field could be moving forward in the years to come. The topics covered in this volume include: Optics and photonics in nature Bio-inspired optics The role of structure: order vs disorder in bio-photonic systems The role of composition: natural materials vs synthetic composites

Due to the intrinsic complexity of photochemical reactions, they remain the least understood type of chemical process. Nonadiabatic dynamics, ultrafast time-scales, quantum effects and conical intersections are known to be important, but a detailed comprehension remains elusive. However, new experimental techniques capable of monitoring photochemical processes in unprecedented detail are appearing. Many of these techniques are being developed by research communities not traditionally concerned with photochemistry, but provide an opportunity to shed new light on photochemical dynamics. This Faraday Discussion brings together experimentalists and theoreticians working from different perspectives in the field. It provides the opportunity to identify how new techniques can complement each other, to address contention and controversy, and to propose future research.

There is great interest in converting electricity overcapacity e.g. from renewables; from fuels such as hydrogen and synthetic gasoline; or for the conversion of nitrogen to ammonia. Solid oxide electrolysis offers a high efficiency route to these conversions utilising technology similar to solid oxide fuel cells. However, there are significant differences between electrolysis and fuel cell operation, and the fundamental aspects of electrolysis have received little attention. This Faraday Discussion brings together the research of leading scientists to address the fundamental aspects of solid oxide electrolysis. Research in this field could yield a new clean chemical industry, potentially allowing greater harvesting of renewables by storing excess energy in a more useful and higher energy density form than electricity.

Developments in cryo-electron microscopy are creating new opportunities within structural biology and there is currently great interest in developing cryo-EM as a core tool for atomic level structural biology. Many structural techniques can give atomic or near atomic level information, but lack the ability to study proteins within a near-native environment, for example within a cellular compartment. Cryo-EM provides this opportunity, but despite the recent massive improvements in single particle cryo-EM, obtaining sub-2Å structural information is still a major challenge. Cryo-electron microscopy has undergone significant developments in microscope design, camera technology and data processing regimes, but there are significant challenges that remain and opportunities to explore, many of which must be tackled by the community as a whole, rather than by individual groups. For example, sample preparation is central to electron microscopy and is currently a significant bottleneck in many experiments, and there are significant problems with ensuring the integrity of the field in terms of dealing with inherently low signal-to-noise images. This volume brings together leading researchers from the UK and the international cryo-electron microscopy community to discuss current developments and new challenges in the field. In this volume the topics covered include: Sample preparation in single particle cryo-EM Pushing the limits in single particle cryo-EM Tomographic analysis, CLEM Map/model validation and machine learning in EM

Over the last decade or so, there has been immense progress in the development of tools, both experimental and theoretical, for probing the solid/fluid interface at the nanoscale. These advances open the way towards mechanistic understanding, and potentially prediction, of chemical processes occurring at this interface. Amongst the fields beginning to benefit from such effort is corrosion science, which is primarily concerned with degradation of metallic materials immersed in either liquid or gaseous environments. Thia Faraday Discussion focuses on the nanoscale interfacial chemical processes relevant to corrosion and its control. Corrosion science is becoming increasingly important as we move towards a world where every atom counts, e.g. in maintaining the performance of nano-devices, as well for ensuring sustainability through optimum use of natural resources.

Photochemistry and molecular photophysics have been highly active fields of research for more than half a century; however, during the last two decades synergistic advances in experimental technology and computational methodology have led to a renewed interest in understanding photochemistry and photophysics at the quantum level - photo-initiated quantum molecular dynamics. One of the grand challenges for the 21st century is to develop such a detailed understanding of energy flow in molecules, following the absorption of a photon, that we can begin to develop the knowledge and tools to control photochemistry. Photo-initiated quantum molecular dynamics is not only core fundamental science, it has potentially wide impact. Perhaps one of the most compelling reasons for developing a more detailed understanding of energy flow in molecules between light, electrons and chemical bonds, is to enable us to contribute to some of the challenges in designing light harvesting systems for clean energy generation thus addressing one of the big problems facing society. There are also important applications in fields such as photocatalysis, the design of efficient light-driven molecular devices for data storage and processing, and photomedicine.

There is much speculation about the chemistry occurring in astronomical environments, but without observation of such environments, speculation is without foundation. Observational astrochemistry is the foundation on which astrochemistry is built. It offers us a window into a world that would otherwise be beyond our reach. Chemical spectroscopy helps identify chemical species and probe their environments; gas-phase, surface, solid-state and photochemically-induced chemical processes drive the evolution of our galaxy and others; chemical evolution controls the formation of stars and planets; chemistry is the forerunner that brings us to the edge of biology and of life itself. This window to our universe is being opened more widely as a revolution in the observational capabilities available to astronomers is expected to continue through the 2020s and beyond. Join internationally leading experimental and theoretical scientists from across the fields of astronomy, chemistry and physics to explore and exchange ideas about our chemical understanding of the universe. The topics are organised into the following sections: Observational astrochemistry in the age of ALMA, NOEMA, JWST and beyond Laboratory astrochemistry of the gas phase Laboratory astrochemistry of and on dust and ices Computational astrochemistry

Industrial-scale ammonia synthesis, as accomplished by the Haber–Bosch process, was a landmark achievement of the 20th century. However, as currently practiced, including feedstock generation, the process accounts for 1–2% of global energy demand and contributes significant fossil-fuel-based CO2 emissions. Accordingly, there is much contemporary interest in developing more sustainable ammonia synthesis routes which could, for example, be operated on the local scale employing renewable energy. The five themes of this Faraday Discussion unite different research communities around a topic of mutual interest and great societal importance, with particular emphasis placed upon the transfer of learning between the different themes. The discussion focuses on the following themes: Heterogeneous catalytic and chemical looping routes to N2 activation Electrocatalytic and photocatalytic routes to N2 activation Enzymatic N2 activation Homogeneous N2 activation Alternative routes to NH3 and its applications

Heterogeneous catalysis is a core area of contemporary physical chemistry posing major fundamental and conceptual challenges. Catalysis lies at the heart of the chemical industry - an immensely successful and important part of the overall UK economy, and catalysis plays a crucial part in the production of 80% of all manufactured goods. Catalysis is a major theme in the chemical sciences and engineering that underlies much of the key research and teaching in these subjects. The reaction mechanisms of many commercial processes although successfully operated, are still a matter of debate and controversy, e.g. methanol synthesis and the Fischer–Tropsch process.

Ultrafast energy and charge transfer events dictate the functionality of a broad range of molecular, aggregate and nanomaterial systems. Impressive recent advances in the commercialisation of ultrafast laser technology and on many theoretical fronts, plus the societal emphasis on solar energy, have led to a surge of research in this community, encompassing spectroscopists, biophysicists, computational and theoretical chemists, physicists and materials scientists. Ambitions have evolved beyond studies of simple molecular systems, and increasingly focus on the underlying molecular mechanisms prevailing in nanomaterial, native protein and hybrid systems.

This volume will focus on the chemistry, physics and material sciences contributions toward the rapidly evolving field of artificial water channels. The development of synthetic biomimetic artificial water-channels and pores is key for a better understanding of the natural function of protein channels. It is hoped to offer new strategies to generate highly selective, advanced materials for water purification systems. While synthetic chemists have produced sophisticated architectures able to confine water clusters, most water channel based work is being conducted with natural protein channels as selectivity components, embedded in the diverse arrays of bio-assisted artificial systems. Experimental results have demonstrated that natural biomolecules can be used as bio-assisted building blocks for the construction of highly selective water transport through artificial channels. Moving to simpler water-channel systems offers a chance to better understand mechanistic and structural behaviours and to uncover novel interactive water channels that might parallel those in biomolecular systems. In this volume the topics covered include: Structure and function of natural proteins for water transport Biomimetic water channels The modelling and enhancement of water hydrodynamics Applications to water transport systems

The quantum mechanical properties of small molecules provide the basis for our quantitative understanding of chemistry and a testing ground for new theories of molecular structure and reactivity. With modern methods, small molecular systems can be investigated in extraordinary detail by high-resolution spectroscopic techniques in the frequency or the time domains, and by complementary theoretical and computational advances. This combination of cutting-edge approaches provides rigorous tests of our understanding of quantum phenomena in chemistry. The chemical properties of small molecules continue to present rich challenges at the chemistry/physics interface since these molecules exhibit properties in isolation, and interact with their environments, in ways that are not yet fully understood. The coupled electronic and nuclear motions may lead to complex structural or dynamical features that can now be observed experimentally. From a theoretical point of view, these features can only be explained if the quantum nature of the atomic nuclei is considered together with the possible couplings between nuclear and electronic degrees of freedom. New developments, from both the theoretical and experimental side, are urgently needed if the properties of small molecules are to be optimally exploited in future technological, engineering and biological applications of outstanding importance. This Faraday Discussion will address the quantum dynamical properties of small molecules, both in isolation where extraordinarily detailed and precise measurements and calculations are now emerging, and when embedded in complex media such as molecular clusters, quantum fluids and bulk liquids. The Discussion will appeal to researchers working on both isolated and confined molecular systems. This volume covers four main themes: Precise Characterisation of Isolated Molecules Quantum Dynamics of Isolated Molecules Molecules in Confinement in Liquid Solvents Molecules in Confinement in Clusters, Quantum Solvents and Matrices

Carbon nanomaterials have a unique place in nanoscience owing to their exceptional electrical, thermal, chemical and mechanical properties and have found application in areas diverse as composite materials, energy storage and conversion, sensors, drug delivery, field emission devices and nanoscale electronic components. Conjugated carbon nanomaterials cover the areas of carbon nanotubes, fullerenes and graphene. Carbon nanotubes continue to gain attention and have impacted many fields and the number of potential applications continues to grow. The chemistry of carbon nanotubes, control over electronic properties and the assembly of nanotube devices are particularly active areas. Work in fullerenes has renewed vigour with significant advances in the field of superconductivity, thin films and supramolecular assembly being made over the last few years. Graphene is perhaps the newest of the carbon nanomaterials and promises to be a very active field. Already since its 'isolation' in 2004 it has grabbed the attention of the chemistry, materials and physics communities. It promises to rival carbon nanotubes in terms of properties and potential applications with the number of publications rising from ca. 130 in 2005 to ca. 2,800 in 2010. The discussion covers three key areas: carbon nanotubes, fullerenes and graphene which although look very different have much, often unrealised, common ground. Much of the work on carbon nanotubes has origins in fullerene research and now graphene is building on carbon nanotube work.

Over the last three years, there has been an increase in the range of ionic liquids utilised and significant advances in our understanding of the fundamental aspects of these materials. Therefore, the time is apt for Faraday Discussions to provide a foundation for future fundamental challenges and theories that need to be developed to move the subject area forward. This meeting follows on from Faraday Discussion 154 held in 2011 and discusses a range of topics, such as ionicity, structure, electrochemistry, phase behaviour, and introduce areas which were only emerging at that point, such as interactions with liquid and solid interfaces. Ionic liquids have been the focus of intense research over the last 20 years because of their remarkable potential for applications coupled to favourable environmental properties. Ionic liquids are also a medium whereby the nature of the complex interactions (Coulombic, van der Waals and hydrogen bonding) provides a liquid whose structure and properties can be tuned by the choice of the cation and anion wherein reactions are likely to be distinct in terms of activity and selectivity profiles compared with common molecular solvents.

Gaseous ion spectroscopy generally couples mass spectrometry with a class of high-resolution laser spectroscopy, providing a route for studying the intrinsic chemical and physical properties of isolated ions. The isolation of the molecular ion of interest from its native environment is important to decouple the influence of the surroundings from the intrinsic properties. The effect of the environment can then be incrementally re-introduced through studies of sequentially solvated clusters, which allow the interaction with solvent molecules with the ion to be studied on the molecular level. The field of gaseous ion spectroscopy has the potential to impact a wide range of chemical, physical and biological problems and it has seen a rapid diversification in the past decade with the application of different ion sources, cryogenic ion traps, and new light sources such that this potential impact is rapidly being realised. This Faraday Discussions volume focusses on experimental and theoretical ion spectroscopy, highlighting the latest innovations and applications in the field. These range from the IR spectroscopy and anion formation mechanism of molecules in the interstellar medium, to the intrinsic structure of catalytic centres in chemical reactions, to the ultrafast dynamics of bioactive chromophores, to exotic ionic systems such as Coulombic crystals and dipole-bound anions. This volume provides a roadmap of where the field is and what the challenges will be over the next 5-10 years and beyond. It covers four main themes: Controlling internal degrees Pushing resolution in frequency and time Going large(r) Exotic systems

The global generation of power depends heavily on coal-fired power plants, and industrial processes such as the production of cement or iron emit CO2 as an intrinsic part of the process. As fossil fuels will remain part of the global energy mix for some time, developing carbon capture and storage technologies is becoming increasingly important for reducing carbon emissions. Topics covered include a review of the technologies likely to be deployed in the first generation of carbon capture and storage plants; potential technologies for CO2 capture, such as metal-organic frameworks and nanoparticle-organic hybrid materials; recent advances in modelling, including thermodynamic theories; and end uses for CO2, such as fuels, building materials and plastics. This Faraday Discussion brings together researchers working on new potential carbon capture materials and processes, physical properties of CO2 and gas mixtures, carbon dioxide utilisation and process engineers looking at incorporating new technologies into viable carbon capture and storage processes.

This volume focuses on assessing recent progress in our general understanding of coherence and control in chemistry and defining new avenues for future research. The prospect of exploiting quantum interference to direct the outcome of a chemical reaction is known as coherent control. Over the last twenty years or so, many schemes to exploit the coherence property of laser light have been proposed to exert such control over molecules, and in the last decade or so these have become realisable through advances in laser and pulse shaping technology. Many practical demonstrations of molecular coherent control, with applications ranging from laser cooling of molecules to chemically selective bond breaking or the generation of coherent x-ray light through high harmonic generation, have been made. We now also know that many photochemical reactions of fundamental importance in biology appear to exploit quantum coherence in order to transfer energy efficiently to do work rather than dissipate the energy as heat. This volume brings together experimentalists and theoreticians working in all areas of physics and chemistry who have an interest in probing and controlling chemical interactions at the quantum resolved level.

Density functional theory (DFT) is today’s most widely used method for practical computational electronic structure calculations across chemistry, physics and materials science. It is not only the first choice for running simulations, but it has also delivered an alternative view-point for thinking about the electronic structure of an enormous range of molecular and solid state systems. Fuelled by a rapid increase in computational power and the advent of linear scaling technologies the systems to which DFT may be applied have become ever larger, more complex and more diverse. This rapid growth in the range of problems that may be subjected to computational study has often highlighted new challenges for DFT methodologies in terms of accuracy, speed and scope, spurring many new developments in the field. This Faraday Discussions volume is for chemists, physicists, materials scientists and applied mathematicians who develop new density-functional methods and rely on this approach as a key tool in their research. By discussing the latest cutting edge developments and their relative merits this volume should help bring these new methods to practical application quickly and effectively. It focuses on the following four themes: New density-functional approximations and beyond Challenges for large scale simulation Strong correlation in density-functional theory New approaches to study excited states in density-functional theory

Structure determination of molecules contained within unresolved complex mixtures represents an unsolved question that continues to challenge physical and analytical chemistry. Most naturally occurring systems can be characterised as complex mixtures. These can be broadly divided according to the molecular sizes of their constituents, into mixtures of small or large molecules; the focus of this volume is on the former. While large molecules such as biomacromolecules, industrial polymers, or solid matrices are outside of the scope of this volume, the processes that are used in analysing the data originating from these studies may be of interest. Small molecule mixtures include environmental matrices (such as soil, dissolved organic matter, organic molecules contained in atmospheric aerosol particles, or crude oil), biofluids, and man-made mixtures of small molecules such as food, beverages or plant extracts. These systems are generally classed as “complex mixtures” or “unresolved complex mixtures (UCM)”, emphasising our current inability to separate their individual components. The techniques best positioned to tackle such mixtures experimentally include mass spectrometry, chromatography, NMR spectroscopy, or new alternative techniques, including combinations of the above methods. For the most part, people who work on the analysis of complex mixtures are driving the progress in exploiting new methodologies and their creative combinations. In this volume, the topics covered include: Dealing with complexity: latest advances in mass spectrometry and chromatography High-resolution techniques, from high-resolution mass spectrometry to NMR spectroscopy Data mining and visualisation Future challenges and new approaches

Light induced chemical and physical processes in small organic-/inorganic-/bio-molecules have been a subject of experimental and theoretical research for several decades. Recent advances in high resolution spatio-temporal techniques have offered detailed understanding of excited state processes in small molecules. In sharp contrast, however, information on electronic processes in biomolecules such as isolated proteins and DNA (and their complexes) is still in its infancy. Though extremely complicated to uncover, knowledge of photo-excited state processes of such biomolecules in the cellular/biological context is the eventual goal of scientists working in these areas. Photochemical and photophysical processes in biomolecules are intimately involved in a multitude of functional processes, that include vision, photosynthesis, molecular recognition, gene replication, etc., and can be utilized in areas such as photodynamic therapy. Such processes in DNA are also of interest to both the biological and materials communities as memory devices and structural building blocks. In this volume, the topics covered include: Light induced charge and energy transport in nucleic acids and proteins Photocrosslinking between nucleic acids and proteins Light induced damage and repair in nucleic acids and proteins Bionanophotonics
