In this lecture, I will give an overview of the recent developments in the strategies to synthesize supported gold- based bimetallic nanoparticle catalysts. The catalytic efficiency of these supported bimetallic nanoparticles, similar to monometallic nanoparticles, depends on their structural characteristics, but with added complexities because of the presence of the second metal. I will discuss three major structural features of supported bimetallic nanoparticles, namely (a) size, (b) composition and (c) nanostructure, all of which play a crucial role in the resulting overall catalytic performances of the materials. A specific objective of this lecture is to motivate researchers to characterize these supported nanoparticles more thoroughly to investigate their structural features in detail and based on this knowledge design suitable and innovative synthesis strategies to control these properties.

The development of a new process for a commodity chemical.

The discovery, development and commercialisation of a new process for the production of a commodity chemical is a long-term, expensive and therefore strategic decision for any Company. This lecture will try to set out the drivers and barriers to implementing new technology and set out the decision making process used to arrive at the optimum solution. It will be illustrated by a real life example, which has novel chemical catalysis at its heart.

Catalyst Separation/Catalyst Immobilisation – Ian Baxendale, Durham University, UK

How Flow Chemistry Can Be Of Use In Synthesis

Synthetic chemistry is the complex art, science and craft of molecular assembly. As a discipline it has undergone many significant changes over the past centuries as our understanding of the fundamentals of bond forming and breaking including how to exert control over these processes has been refined. Throughout this time the basic approach and apparatus available to the experimentalist has remained relatively constant with the occurrence of test tubes, flasks and beakers being historically synonymous with chemistry. This is still true today in that our approach to synthesis is a batch based practice that utilises laboratory glassware such as round bottomed flasks and a defined sequence of discrete reaction steps, work-ups and purifications.

An alternative approach is being evaluated based upon the concept of flow chemical processing which makes use of small capillary reactors and packed bed columns as dynamic vessels for performing chemical transformations.1,2 This more holistic approach also attempts to integrate other aspects of the synthesis such as work-up and purification into the overall process delivering a clean product as one single operation. Consequently the ability to further telescope and assimilate these individual transformations into more elaborate sequences enables the generation of advanced product outputs.

This presentation will detail some of the basic concepts relating to flow chemistry and highlight the scope of it as a technique using examples from our laboratory.

Ian Baxendale obtained his first degree from the University of Leicester graduating with a BSc 1st class honours in Chemistry. He remained at Leicester to continue his studies pursuing a PhD under the supervision of Prof. Pavel Kocovsky investigating new Organometallic catalysts based on group 6 transition metals for stereoselective allylic substitution reactions.
In 1999 he moved to a postdoctoral position with Prof. Steven V. Ley at the University of Cambridge initially conducting research into Natural Product synthesis prior entering the field of Solid Supported Reagents and Scavengers. In 2003 he was awarded a Wolfson Royal Society Fellowship. In 2005 he co-founded the Innovative Technology Centre (ITC) with Prof. Ley as a centre of excellence for the study and development of advanced chemical synthesis tools and methodologies where he was the executive director. In 2008 he was promoted to a Senior Research Associate within the Department of Chemistry at Cambridge and then in 2009 was awarded a prestigious Royal Society University Research Fellowship and become a member of the department faculty.
Whilst at Cambridge he was also elected a Fellow at Sidney Sussex College (2000) and soon after took over as the Head of Natural Sciences teaching and for 5 years acted as the Dean of the College. In 2012 he moved to Durham to take up the Chair of Synthetic Chemistry as a fully tenured Professor.
His current research interests are the design and implementation of new enabling technologies such as Flow Chemical Synthesis (FCS), Synthesis Automation Methodologies (SAM), microwave reactors and immobilised reagents and scavengers to expedite complex chemical syntheses. The success of my academic career is reflected by >150 publications (H-index=47), including several reviews and book chapters, with a total of >5800 citations.

Fungal Biology and Recombinant Enzyme Optimisation – Ronald de Vries, CBS-KNAW, The Netherlands

Ronald P. de Vries, CBS-KNAW Fungal Biodiversity Centre

The kingdom fungi is highly varied and contains both unicellular (yeasts) and multicellular (filamentous) species as well as some that can exist in both morphological forms. Fungi are present in all natural and manmade environments and have both beneficial as well as antagonistic effects on society. Several fungal species have a long history of use in human society, dating back several 1000’s of years. Examples of these are production of beer, wine, bread and soy sauce.

The specific biological features that are at the basis of these applications include both common physiological characteristics of these organisms as well as highly diverse aspects that make the individual species particularly suitable for their natural biotope. In this presentation examples of both types of aspects will be provided.

One of the critical aspects in the use of fungal enzymes for biotechnology is the production cost of the enzymes. Especially in the genomic era where a wealth of novel enzymes can be discovered in fungal genome sequences, the recombinant production of these novel enzymes in established fungal production hosts is of major importance. Depending on the origin of the enzyme, the success of such a process varies, but several strategies can be used to improve their production. Examples of these strategies will also be provided.
