Scalability of heterogeneous MW-heated processes
Mark H.C.L. Dressen, Bastiaan H. P. van de Kruijs, Jan Meuldijk, Jef A. J. M. Vekemans, Lumbertus A. Hulshof

The combination of flow chemistry and microwave heating offers a unique opportunity to scale out heterogeneous microwave-assisted organic reactions. The feasibility of this setup is depending on the presence of a microwave effect, safety issues and energy efficiency.

A Modular Solution for Storage of Biological Samples
Joby Jenkins, Wayne Bowen, Ben Schenker, Chloe Milburn

The physical and chemical composition of biological samples is more diverse than the libraries of medicinal compounds used for drug discovery research. Types of samples include proteins, nucleic acids, blood and serum samples, cell suspensions, tissue biopsies, and antibodies. Thus any storage system must be flexible to accommodate the differing storage requirements of each sample type base upon its biochemical composition, stability and where appropriate, solvent.

Low Volume Liquid Handling of Organic Solvents for Compound Storage and Dissolution using mosquito
Gillian Lewis, Tristan Cope, Joby Jenkins, David Gledhill & Rob Lewis

mosquito® is a positive displacement liquid handling system capable of pipetting solutions with a high degree of accuracy (to within 5%) and precision (CVs of <10%) in the nanolitre range. Here, we demonstrate mosquito’s ability to dispense accurately low volumes of organic solvents of low surface tension and to re-dissolve compounds which have been previously dried in storage wells.

Palladium-Catalyzed Three-Component Synthesis of Phenothiazines
Troels Dahl, Christian Wenzel Tornøe, Benny Bang-Andersen, Poul Nielsen and Morten Jørgensen

The formation of aromatic carbon-heteroatom bonds has traditionally been achieved by nucleophilic aromatic substitution or via the copper-mediated Ullman reaction. The palladium-catalyzed formation of aromatic C-N bonds extensively developed by Hartwig and Buchwald has provided a powerful alternative. While the aryl amination reaction is applicable even to aryl chlorides and activated phenols, the analogous C-O and C-S bond forming reactions have attracted less attention.

Combinatorial synthesis of oxazolidin-2-ones using Fmoc-Ser(Trt)-OH, a library with high degree of diversity
Marek Korinek, Vaclav Stastny and Miroslav Havranek

A library of oxazolidin-2-ones was prepared by solid phase synthesis. Crutial reaction steps were optimized. Highly divers building blocks were selected for the synthesis. All compounds were purified using preparative LC/MS with mass directed fraction collection.

High Throughput Surface Tension Measurement
Neil L. Campbell, Jon Weaver

Understanding the surface tension properties of aqueous surfactants and polymer materials is important for the pharmaceutical, coatings, paints, inks, surfactant and household products industries. The traditional methods of measuring surface tension are tedious and time-consuming, so only a few compounds can be measured by a single user per day.

High Throughput Microwave Synthesis of Metal Organic Framework (MOF) Libraries
Neil L. Campbell, Jake Grace, Richard W. Dewson, Jean-Noel Rebilly, Darren Bradshaw, Ben Carter, Andrew I. Cooper and Mathew J. Rosseinsky

Metal-organic frameworks (MOFs) are an emerging class of new nano-porous materials of considerable academic and industrial interest due to their potential applications in gas storagechiral separations and catalysis. MOFs are prepared from the self-assembly of metal ions (nodes) and organic ligands (spacers), where the structural topology of the resulting crystalline frameworks is driven by the co-ordination preferences of these nodes and spacers. MOFs offer opportunities not available to more cl

High Throughput Polymer Latex Synthesis and Purification Process
Neil L. Campbell

Polymer latexes are essential components in a wide range of commercial products and formulations such as, paints, cosmetics, coatings, biotechnology and functionalised supports. Many difficulties are intrinsic in the implementation of polymer latex research, particularly in purification of the latex dispersions, making high throughput research in this area especially challenging.

Efficient discovery and optimization using high-throughput experimentation and Predictive Design Technology™
James N. Cawse

The new emphasis of high throughput experimentation is the discovery of “hits” by searching extensive experimental spaces. These have the issues of: • High-dimensions; • Synergies (nonlinear interactions) ; • Unpredictable behavior. ProtoLife Srl has developed Predictive Design Technology™ (PDT™) to deal with these issues using proprietary algorithms. It been successfully tested in complex experimental spaces involving drugs, catalysts, and formulations.
