Porous materials adsorb H2 through physisorption, a process which typically has a rather low enthalpy of adsorption (e.g. ca. 4 to 7 kJ mol(-1) for MOFs), thus requiring cryogenic temperatures for hydrogen storage. In this paper, we consider some of the issues associated with the accurate characterisation of the hydrogen adsorption properties of microporous(More)
Dear Sir , In accordance with the requirements of the degree of Electrical Engineering, I present the following thesis entitled " The Use of Pseudo Random Noise Signals in the Excitation System of Synchronous Machines to Identify their Parameters ". that the work submitted in this thesis is my own, except as acknowledged in the text, and has not been(More)
Summary form only given. With the long-term future of fossil fuels in considerable doubt, Europe's roads are seeing the arrival of the first electric vehicles (EVs); the majority of which are hybrid EVs. Crucial to the widespread uptake of pure EVs is the development of superior next-generation electric motors; which will require improved, sustainable and(More)
Quick on the uptake: Following its identification during a targeted search, the intriguing crystal structure of 3,3',4,4'-tetra(trimethylsilylethynyl)biphenyl was investigated. Simple removal of the included solvent provides an organic crystal with an open microporous structure that has a striking similarity to that of zeolite A (see picture). Reversible(More)
