Abstract:
Organocatalysts have been extensively studied for the past few decades as alternatives to transition-metal catalysts. Immobilizing organocatalysts on polymer supports allows easy recovery and simple product purification after a reaction. Select examples of recent reports that describe the potential advantages of using soluble polymers to prepare soluble polymer-supported organocatalysts useful in organic synthesis are reviewed.

Abstract:
Cell membranes are composed primarily of amphipathic lipids either in a single circular layer or as a bilayer in which all of the hydrophilic and hydrophobic groups face the same direction respectively. Diffusion across a lipid membrane can occur spontaneously or be facilitated by integral membrane proteins. The extent of this diffusion relies on the structure of both the membrane and the diffusing species. Artificial lipid membranes that mimic some of the properties of natural cell membranes can be prepared on synthetic supports for use in membrane-based biosensors. We are working to develop

Abstract:
One of the most promising families of catalyst support materials from the point of view of durability in the PEFC are metal oxides. SnO2 can only corrode, in a strong acid, at potentials ! 1.4V, progressing through surface hydroxide formation. The bulk stability is backed up by simulated potential cycling, with minimal ESCA loss at 1.6V. The conductivity of pure SnO2, which forms the rutile crystal structure, is very small compared to C but can increase by orders of magnitude with formation of certain intrinsic defects which create electron donor levels in the band gap (which, at 3.6 eV, class

Abstract:
Polymer Electrolyte Membrane fuel cells (PEMFC) are clean and efficient electrochemical energy converters that can be adapted to a wide range of domestic and automotive applications. However, large-scale commercialisation is hindered by issues of cost and durability relating to the catalyst layer. This work aims to address the need for cheaper and durable catalysts through the development of novel catalyst and catalyst support. The initial aim of this work is to investigate the potential application of Pd-based alloy catalyst in PEMFC. Pd is about 42% cheaper than Pt and 50 times more abundant

Using the general solution, analytical expressions of thermal distortion and associated internal forces for commonly used end supports are obtained. From these solutions, we discuss the failure mechanism induced by thermal dist
