Alumina and silica Zener pinning particles in sol-gel prepared nanocrystalline ZrO2 and MgO have been characterised using 27Al and 29Si MAS NMR after annealing at various temperatures up to 1200 C. The structures of the ...

Computer modelling techniques have been employed to qualitatively and quantitatively investigate the dehydration of hydroxyapatite to oxyapatite and the defect chemistry of calcium-deficient hydroxyapatite, where a number ...

We demonstrate that domain-average Fermi hole (DAFH) analysis, which has previously been used at the HartreeFock level, remains useful after the proper introduction of electron correlation. We perform a systematic investigation ...

Studies of the kinetics of gelation of an acid-modified waxy maize amylopectin have been performed using gel-time measurements and small- and wide-angle X-ray diffraction. The gel timeconcentration relationship for gels ...

In 1974 a Faraday Symposium1 was held at the Royal Institution on the subject of The Physical Chemistry of Oscillatory Processes. That timely event brought together an international group of specialists in the newly ...

We present real-time and in situ atomic force microscope (AFM) observations of solution growth on the cleavage plane of two minerals, calcite and fluorite. Different growth behaviours are exhibited: the calcite surface ...
