The crystal structures of o-toluidinium chloride (1), o-toluidinium bromide (2) and two polymorphs of bicifadine hydrochloride (3) have been determined. The polymorphs of 3 differ in their molecular conformation and in their mode of packing. Crystallisation studies and quantum mechanical calculations show that the mor…

A series of solid oxide fuel cells (SOFCs) with anodes containing mixtures of either Cu and Ni or Cu and Co, prepared by impregnation of the metal salts into porous yttria-stabilized zirconia (YSZ), were examined for operation with both and n -butane fuels at 973 and 1073 K. The Cu-Ni mixtures formed single-phase allo…

Shape memory properties of Ti-Mo-Ag and Ti-Mo-Sn alloys consisting of biocompatible elements were investigated. The alloys with appropriate combination of Mo and Ag or Sn showed nearly perfect shape memory effect in convenient bending and heating tests. Recoverable tensile strain is more than 3% in some of Ti-Mo-Ag an…

Molecular symmetry has a pronounced effect on the melting properties and solubility of organic compounds. As a general rule, symmetrical molecules in crystalline form have higher melting temperatures and exhibit lower solubilities compared with molecules of similar structure but with lower symmetry. Symmetry in a mole…

A plain IF steel and a P-added IF steel having various ultrafine grain sizes from 0.24 to 11 μm were fabricated by the accumulative roll bonding (ARB) process followed by annealing. Dynamic fracture toughness of the ultrafine grained IF steels was investigated as a function of grain size by miniaturized Charpy impact…

Composites of yttria-stabilized zirconia (YSZ) with Sr-doped (LSF) were studied for application as high-performance cathodes for solid oxide fuel cells (SOFCs). The composites were formed by aqueous impregnation of porous YSZ with La, Sr, and Fe salts, followed by calcination at various temperatures. X-ray diffraction…

Second-order nonlinear optical (NLO) polarisabilities or first hyperpolarisabilities, β, of molecules may be manipulated by reversibly modifying the properties of specific parts of active molecules, usually by on/off switching. This may involve reducing the donor capacity of the electron-rich fragment of a typical don…

In this paper, we evaluate the potential use of theoretical calculations to obtain an energy scale of the lowest ligand-centred triplet excited state in luminescent terbium(III) complexes. In these complexes, non-radiative deactivation of the terbium emitting state via a back-energy transfer process (T1<--Tb(5D4)) is…

Roughening or texturing surfaces provides super-liquid repellent or film forming properties without alteration of the surface chemistry. These surfaces are easy to produce, can amplify wetting properties and can be either “sticky” or “slippy” to liquids. Their use as water-repellent coatings is established, but their…

The addition of colloidal shear thickening fluids (STFs) to Kevlar fabrics has been shown to enhance the ballistic penetration resistance of the fabric, under conditions of low velocities and small target sizes. It is believed that this improvement in ballistic properties is related to the resistance of the STF to def…
