The flow properties of proteins and other biopolymers. The living cell is an extraordinary organization with a vast variety of biomacromolecules carrying out myriads of functions with great specificity and accuracy. The key issue in cell biology is to unravel the structures of biopolymers and the deep connection that exists between structure and function.

The living cell is an extraordinary organization with a vast variety of biomacromolecules carrying out myriads of functions with great specificity and accuracy. The key issue in cell biology is to unravel the structures of biopolymers and the deep connection that exists between structure and function. This interdisciplinary research program combines recent advances in experimental and theoretical rheology, with advances in protein science, to investigate the response of biopolymers to deformation. This approach will lead to insights into the problem of protein folding, the interaction of biopolymers with surfaces, and the physical basis for the mechanical properties of biopolymers.Read moreRead less
Porphyrin-Based Supramolecular Assemblies and Arrays - Model Systems for the Construction of Photosynthetic Mimics. Crown ether-based multichromophoric systems will be used to mimic the steps through which plants convert light into chemical energy. The crown bridging units allow a variety of metal and organic cations, which provide electronic and structural roles, to be non-covalently bound within their cavities. These systems are advantageous over other photosynthetic models in that a variety ....Porphyrin-Based Supramolecular Assemblies and Arrays - Model Systems for the Construction of Photosynthetic Mimics. Crown ether-based multichromophoric systems will be used to mimic the steps through which plants convert light into chemical energy. The crown bridging units allow a variety of metal and organic cations, which provide electronic and structural roles, to be non-covalently bound within their cavities. These systems are advantageous over other photosynthetic models in that a variety of electron transfer mediators can be examined in a readily controlled and systematic way simply through the choice of cation. In this way, the role played by molecular recognition in the modulation of long-range electron transfer can be evaluated. This work will lead to designing better artificial solar energy converters and molecular electronic devices.Read moreRead less
The Baylis-Hillman Reaction: Asymmetric Organocatalysis and Applications. Many drugs come in two chiral mirror images (enantiomers) where the therapeutic effect is usually associated with only one while the other has no effect or can be harmful as was the case with thalidomide. Chemical reactions that yield just the desired mirror image, or enantiomer, and not the other are therefore in great demand and heavily pursued by the pharmaceutical, fine chemical and materials industries as a frontier ....The Baylis-Hillman Reaction: Asymmetric Organocatalysis and Applications. Many drugs come in two chiral mirror images (enantiomers) where the therapeutic effect is usually associated with only one while the other has no effect or can be harmful as was the case with thalidomide. Chemical reactions that yield just the desired mirror image, or enantiomer, and not the other are therefore in great demand and heavily pursued by the pharmaceutical, fine chemical and materials industries as a frontier technology. This project will result in the development of novel catalytic reactions that allow the synthesis of chiral chemicals in a cost-efficient and green manner needed by many industries, and also training of students with highly desirable synthetic skills to lead the next wave in pharmaceuticals and biotechnology.Read moreRead less

Elemental and Structural Analysis Facility Comprising a FTICR Mass Spectrometer and a CHNS Analyser. The determination of molecular structure is important in many fields of chemistry, biochemistry and material science. Without such determinations much chemical research would be viewed as incomplete and rendered unpatentable as well as unpublishable.

The determination of molecular structure is important in many fields of chemistry, biochemistry and material science. Without such determinations much chemical research would be viewed as incomplete and rendered unpatentable as well as unpublishable. The two state-of-the-art instruments to be purchased will improve the ability of a wide cross-section of researchers to rapidly characterize compounds important in fields as varied as medicinal chemistry, material science and geosciences. All types of chemical research, from fundamental to applied, will benefit from these instruments with clear and positive implications regarding societal impact.Read moreRead less
The formation of negative ions and neutrals in the gas phase. Structure, reactivity and mechanism. Mass spectrometry is an analytical technique used to provide information concerning the structure of a chemical compound: it is particularly useful when dealing with small amounts of biologically important molecules.

Mass spectrometry is an analytical technique used to provide information concerning the structure of a chemical compound: it is particularly useful when dealing with small amounts of biologically important molecules. It is also a facility in which charged species can be converted into transient neutrals. This project will (i) produce information about negative ion fragmentations in order to extend the applicability of analytical negative-ion mass spectrometry, (ii) form neutral molecules and related species which are found in stellar dust clouds and investigate their chemistry, and (iii) train graduates in ion chemistry to the highest international standards.Read moreRead less

The role of mechanosensitive (MS) ion channels in magnetoreception. The magnetic field of the Earth has for long been known to influence the behaviour and orientation of a variety of organisms. Experimental study of the magnetic sense has however, been impaired by the lack of a plausible cellular and/or molecular mechanism providing meaningful explanation for detection of magnetic fields by living organisms.

The magnetic field of the Earth has for long been known to influence the behaviour and orientation of a variety of organisms. Experimental study of the magnetic sense has however, been impaired by the lack of a plausible cellular and/or molecular mechanism providing meaningful explanation for detection of magnetic fields by living organisms. Recently, mechanosensitive (MS) ion channels have been implied to play a role in magnetoreception. Based on our preliminary investigations, which suggest that the activity of bacterial MS channels may be affected by magnetic fields, we propose to study effects of magnetic fields on MS ion channels in Gram-negative bacteria Escherichia coli and Magnetospirillum magnetotacticum. The project promises also to contribute towards better understanding of adverse effects of electromagnetic radiation on human health and towards understanding the mechanisms behind remote magnetic-nanoparticle mediated activation of MS ion channels.Read moreRead less
