Control of crystallization by non-photochemical nucleation
Nucleation is a fundamental process that pervades the sciences but remains awkward to study due to its stochastic nature. Laser-induced nucleation shows tremendous promise in allowing us to control both the timing and location of nucleation. In this talk we discuss the successes and limitations of this technique. We also offer new perspectives on the structure of aqueous solutions: Do pre-nucleating clusters exist? Can we track down the elusive nanobubble?

An Information-Theoretic Approach for Modeling Minimally Cognitive Agents
The importance of entropy and the closely related (Shannon) information is well established in physics. However, Ashby's Law of Requisite Variety (1956) and its later rediscovery and extension by Touchette and Lloyd (2000, 2004), as well as the considerations of the Landauer Principle (Landauer 1961; Bennett and Landauer 1985) show that the relevance of information extends beyond the physical into the computational realm.
In the relation between low-level computation and high-level cognition in organisms, many questions have remained open because of the complexity of organismic information processing. In recent years, however, it has become increasingly clear that it is not essential to have a detailed picture of cognitive mechanisms to understand the core requirements for organismic information processing. Instead, one can use informational principles to model many relevant aspects of the cognitive dynamics of organisms in a minimalistic fashion (Polani 2009). Specifically, by modeling Shannon information flows in agents one obtains invariants, variational principles, as well as adaptive and evolutionary drivers which help to understand the cognitive dynamics of the agent. A "cartoonish" way of putting this would be: "If physics is about the dynamics of energy flows, cognition is about the dynamics of (Shannon) information flows".
In my talk, I will give an overview over the general methodology and a few "appetizer" examples for cognitive phenomena that can be modelled using Shannon information.

STM of Individual Dopants in Silicon towards Devices for Quantum Information Processing
The study of individual Group V donors in silicon is important due to their potential
application in spintronics and quantum computing. Recently a new programme has begun
with the aim of developing completely new, single dopant-derived devices in silicon
with functions based on principles from atomic physics – namely those of long-lived
quantum states and interactions between them and radiation fields.* If the project is
to be successful, the ability to position, characterise and manipulate individual
dopants in silicon must be established. I will describe our on-going efforts towards
these aims and show that it is possible to study individual Bi and Sb atoms in the
cleaved Si(111)2x1 surface, using a combination of ion implantation and cross-sectional
scanning tunnelling microscopy (XSTM). High resolution STM topography images and
scanning tunnelling spectroscopy (STS) data allow the experimental comparison of the
different structural and electronic properties of these individual group V donors, for
the first time. In addition, we have discovered an interesting strain effect in the
Si(111)2x1 surface that may provide a mechanism for controlling the local electronic
environment of individual dopants.

The Good, the Bad, and the Bubbly!
My group have been studying acoustically driven bubbles, ostensibly for their potential medical
applications, since 2004. During this period we have developed a protocol that integrates optical
tweezing for spatial control, with high speed imaging to resolve bubble behaviour at MHz framing
rates. Here, single bubbles exhibit some unusual features, especially when driven at high amplitudes,
where their non-linear response can lead to the development of extremely high core energy densities
during the collapse phase: a process underpinning phenomena such as sonoluminescence and even plasma
formation. When rigid surfaces (such as endothelial cells in a tissue plane) are nearby during
cavitation, bubbles are then predisposed to asymmetric collapse, often forming fast moving liquid jets
that potentiate localised surface damage and facilitate drug or gene delivery in a controlled manner.
Moreover, when scenarios involving multiple bubbles are developed and observed, a new level of
richness in the prevalent physical phenomena emerges.
In this talk, I will give a review of the technology that we developed, and the salient features of
single and multiple bubble behaviour in acoustic fields, especially in the context of their therapeutic
potential. Notably also, we gathered all of our data using a high speed camera borrowed from the EPSRC
instrument loan pool, and which has a variety of interesting quirks that will be discussed and
explained at length, lest some other wretched souls trip headfirst into the pitfalls that we have
previously encountered.

Thesis Hell
Almost everybody I speak to hates writing their thesis. After years of training as a researcher,
suddenly, under pressure, you are expected to write the equivalent of a short novel, as writer,

or an uphill struggle, but both marathons and mountains are easily conquered with the right

This talk brings together techniques and anecdotes from writing, marketing, sports training, as
well as techniques for motivation and time management.
Ultimately, thesis hell is avoidable through forming the right habits. This talk will tell you how.

Progress Towards Atomically Precise Manufacturing via Patterned Si Atomic Layer Epitaxy
Improved manufacturing precision is second only to human innovation in driving economies, science and technology, security, and an improved standard of living. As current manufacturing precision has pushed into the sub nm regime (at least in one dimension) the opportunity exists to take advantage of the quantized nature of matter and make precision absolute. Zyvex Labs is leading a team to develop a fabrication process that is scalable, and will produce, under computer control, three-dimensional covalently-bonded structures where the position of every atom is controlled. The technology is based on the
integration of H depassivation lithography with a Scanning Tunneling Microscope and Si Atomic Layer Epitaxy. The presentation will cover progress toward this goal with respect to lithography, tip technology, understanding of the epitaxial process, and an initial estimation of
products that could be produced cost effectively with this technology.

Functionalising Silicon with Organic Molecules
Measuring the electrical conductance of individual molecules is an exciting field of nanoscience research that holds promise for the creation of the next generation of technology. In this talk, I will outline a programme of research aimed at measuring the conductance of individual molecules by attaching them to semiconductor surfaces and contacting them using a scanning tunnelling microscope (STM) tip. The first stage of the proposed methodology is to investigate ways of attaching organic molecules to semiconductor surfaces such that they form stable adsorption configurations so that their conductance can be measured without the molecule undergoing structural rearrangements. I will present combined STM and density functional theory data demonstrating that the acetyl group (–COCH3) can be used to attach organic molecules to the silicon (001) surface in such a fashion. One particularly interesting example is the acetophenone molecule, which I will show can be reversibly switched between two nearly isoenergetic surface configurations. In addition, through low temperature annealing, this molecule can be made to stand upright on the surface, presenting an interesting candidate structure for performing molecular conductance measurements. I will conclude by describing recent low temperature tunnelling spectroscopy measurements of the bare Si(001) surface performed at LCN, which are the precursors to molecular conductance measurements that are scheduled for the second half of 2010.

Approaches for the Assembly of Matter at the Atomic Scale
Can we conceive or create an automated system that can construct any arbitrary molecule with atomic precision from given ‘blue prints’? In particular what such a ‘nano-assembler’ should be able to do and how? One approach is the use of scanning probe microscopy for the manipulation and construction of arbitrary molecules predominantly on a given surface. This new ‘pick and place’ type synthesis has been demonstrated experimentally in the past. Such experiments involved manipulation of molecules, creating and breaking bonds at single atom level and synthesising even molecules using scanning probes on specific substrates. However, the mechanistic application of such type synthesis to the assembly of arbitrary molecules requires the development of systematic methodologies and enabling technology that will be result of multidisciplinary research spanning physical sciences, computing and engineering. This talk is concerned with recent developments in the area and will discuss findings relating to Si based systems.

Thin film model for the formation of periodic deposits during the dewetting of suspensions
Experiments involving evaporating films or meniscii of colloidal suspensions or polymer solutions often show the deposition of regular patterns at the receding contact line, e.g. concentric rings or periodic line patterns of deposited polymers or nanoparticles, formation of fingers perpendicular to dewetting front [1,2,3].
We use a simple model based on lubrication approximation extending a model used for a evaporating pure liquid [4,5]. We numerically analyze the conditions for the formation of periodic line patterns in the dewetting process. Thereby we focus on exploring the parameter range where patterns occur and study the variation of their properties. We compute characteristic measures of the line cross sections and compare them to experimental results.

Dynamical density functional theory: a description of the theory and of recent applications to the dewetting of evaporating thin films of nanoparticle suspensions exhibiting pattern formation
I will describe the dynamical density functional theory (DDFT), which is a theory that has been developed over the last decade to describe the fluid dynamics of colloidal suspensions [1,2]. The theory can predict the time evolution of the fluid density distribution(s) down to the scale of the individual particles in the suspension. I will discuss various applications of the theory, focusing on recent work where a DDFT has been developed to model the time evolution of the density of a thin liquid film evaporatively dewetting from a planar substrate. In particular, we consider the case when the film contains colloidal nano-particles. As the liquid evaporates and dewets in an inhomogeneous manner, the nano-particles may be deposited non-uniformly on the substrate. Fingered and other self-assembled patterns may be observed. The present theory is able to describe these effects, in agreement with the recent experimental and simulation results (using a kinetic Monte Carlo) of Pauliac-Vaujour etal. [3].

Towards the `Superatom`: Experiments with Clusters in the Gas Phase, in Liquids and on Surfaces
Metal clusters show a great sensitivity to electronic shell closure and geometric symmetry effects. Each constituting atom contributes valence electrons to the entire cluster; shell-closure depends on the stoichiometry of the metal atoms and thus on the clusters chemical composition. Doping, in fact,
represents a powerful means to tune cluster properties to specific applications [1]. By designing clusters of the right size and right chemical composition it should be possible to create 'superatoms' of increased chemical stability that could, for instance, replace noble metal atoms in catalysts. However,
the locations of the dopant atoms are also important because a foreign atom put in the right place can minimise strain and thus lower the total energy or provide a binding link to a surface.
Consequently, a major requirement for experiments is to provide a method of synthesis with control over (i) the stoichiometry and (ii) the geometrical location of the constituents. In this presentation I will introduce the method of clusteraggregation
to produce 'superatoms' and discuss examples of possible experiments. The method uses liquid helium (or other liquid-like) droplets which pass through plumes of metal vapours and sequentially pick-up single metal atoms which become trapped inside the droplets and agglomerate into clusters. When the droplets then pass through a vapour of a different metal these atoms will land on the surface of the previously built cluster thus providing radial control. Reversing the pickup order will lead to clusters which are doped in the centre. A further benefit of the method of cluster aggregation is that it allows us to
soft-land the embedded clusters on a surface because the kinetic energy will be completely absorbed by the host droplet leaving the bare metal cluster behind. Finally, the method allows us to cage clusters by a protective shell to prevent, for instance, fragmentation and the structure of such coreshell
clusters can be assessed spectroscopically. In a proof of principle experiment we could show that single oxygen molecules were caged by two argon layers within a neon cluster [2]. This was possible, because each layer showed a specific fluorescence band and even the interface layer
showed a distinct spectroscopic fingerprint.
I will discuss the advantages of our approach to progressively investigate cluster-host interactions on the example of PdAgn clusters. Recent calculations have identified clusters bound to colour center defects on MgO (100) with magic-like properties [3]. These clusters represent promising candidates to achieve luminescence or functionality. The generation of these clusters by aggregation inside helium droplets will make it possible to investigate their luminescence in the gas phase as well as to land them on defective MgO surfaces and investigate their electronic properties by STS. Furthermore, I will introduce luminescent Si nanoparticles in aqueous suspension that were created by our method [4] as well as Fe nanocrystals landed on carbon surfaces.

Vertically Aligned Nanorod Superlattices: Synthesis, Assembly and Application
Anisotropic nanocrystals such as nanorods have significant potential in a wide range of device applications such as in semiconductor electronics, data storage and third-generation solar-cells. Finding methods to organise functional assemblies whose properties depend on the precise placement of anisotropic components remains a key challenge. Columnar 1D nanocrystals or nanorods primarily adopt assemblies parallel to substrates on deposition whereas axial alignment perpendicular to the substrate is the desired geometry of most interest in key applications The formation of large 2D superlattices of perpendicularly aligned semiconductor (CdS) nanorods on patterned and un-patterned silicon wafers is described in this talk. The pyrolysis synthesised nanorods, 5 nm in diameter, are hexagonally packed into micron sized domains using a range of approaches such as electric field or highly oriented pyrolytic graphite assisted assembly. The nanorod superlattices demonstrate azimuthal alignment from nanorod to nanorod along their hexagonal facets.

Graphite - A New Twist
Carbon is an element that is unique in the variety, utility and individuality of its allotropes. Diamond and graphite each have several unique properties that have been exploited in twentieth century science and technology. Against the landscape of the rest of the periodic table, the discoveries of new elemental carbon materials, fullerenes (1985) and nanotubes (1991), stand out as substantial landmarks. Their beauty lies in the topological conversion of flat graphite sheets into curved molecular forms, which can be isolated, studied and exploited by chemists and physicists alike. Logic demands that other non-molecular, topological conversions must exist and could lead to interesting new materials. I shall show that graphite sheets can be engineered to buckle, fold and/or ‘weld’ together when bombarded by high energy neutrons.
The resulting atomic arrangements, regarded as ‘defects’ in the graphite crystal, are described technically as dislocations or combinations thereof. The identification and characterization of dislocations in graphite gives insight into the complex nature of layered materials and reveal how graphite behaves in nuclear fission and fusion reactors. A potential constructive use could be 3D integrated circuits based entirely on graphite with an appropriate combination of these structural defects.

I shall focus on two particular processes of electric field induced phospholipid phase transitions and ion channel activity and show the relevance of the findings to natural biomembrane function. Finally the future applications of this well studied system will be

Low-dimensional hybrid organic-inorganic and metal-oxide nanostructures -fundamentals and applications
One-dimensional nanomaterials, such as nanotubes, nanowires, and nanobelts or nanoribbons have attracted considerable attention in the past decade because of their novel and useful physical properties leading to numerous applications. Although the majority of research and development has been based on carbonaceous and compound semiconducting nanostructures, considerable attention is now being directed to transition metal nanostructures based on their oxides which, due to their versatile chemical properties often modulable by changes in the oxidation state in the metal co-ordination sphere, can lead to a variety of products and tuneable materials. Incorporating such nanostructures into known device configurations could improve on current designs while potentially allowing further functionality by exploiting nanoscale electronic and photonic properties of suitable materials.
This talk will outline recent findings by our group concerning two particular metal oxides: vanadium oxide and indium tin oxide. Starting from the laminar V2O5 xerogel numerous two-dimensional organic-inorganic VOx intercalation products have been obtained. Many of these V2O5-based nanostructures may be obtained in quantities on the order of grams. The possibility of synthesizing new varieties of shapes and sizes can only be made possible by a better understanding of the molecular conformation of these very ordered structures and will encourage their potential application in new kinds of electrical and charge storage architectures.
In parallel, nanostructures designed for optical emission and absorptive charge storage have garnered obvious interest in recent times, resulting from a drive to research new charge storage architectures and advanced solar cell designs. The ability to realize fully transparent and conductive arrays of indium tin oxide nanowires grown as dedicated, uniform contact layers will be described. The growth method mimics that of standard epitaxial growth regimes for known device architectures, allowing a one-step bottom-up method of both device and epitaxial nanowire layer fabrication. This new molecular beam epitaxial growth method; control of the nucleation, crystal growth direction, nanowire shape, density, conductivity and transparency is possible without necessitating neither a heterogeneous metal catalyst nor predefined placement of nanowire seeding. The electronic and photonic properties of these branched nanostructured arrays are optimized for application as fully transparent contacts in the visible to near-infra red region for silicon-based light emitting devices (LEDs).
