Abstract: A process for the synthesis of hydrocarbons by the Fisher Tropsch process includes reacting a mixture of carbon monoxide and hydrogen at elevated temperature and pressure in the presence of a catalyst including 15-50% wt cobalt at least partially in elemental form, supported on an oxidic support of aluminium, oxygen and 0.5-10% wt lithium, where the oxidic support includes lithium oxides and >75% wt of the lithium oxides are lithium aluminate spinel, LiAl5O8.

Abstract: A catalyst includes 5-75% wt cobalt supported on an oxidic support consisting of aluminium and 0.01-20% wt lithium, and a process for preparing the catalyst. The catalysts are useful for the Fischer-Tropsch synthesis of hydrocarbons.

Abstract: A method for decorating a substrate using novel thiol-stabilised gold nanoparticles of the general formula HSR where R is a C3-C60 alkyl group, aryl, benzyl, alicyclic, or heterocyclic group which is substituted or unsubstituted, branched or unbranched. The thiol-stabilised gold nanoparticles exhibit a plasmon frequency of between 480 and 600 nm.

Abstract: The present invention relates to novel thiol stabilised gold nanoparticles for decorative uses. Methods of their preparation, compositions comprising them and uses of gold nanoparticles and compositions are also described.

Abstract: A glass frit is prepared by heating an initial glass frit in the presence of a reducing agent so as to reduce metal moiety in the glass structure of the frit and then cooling the reaction mixture. Preferably, the frit prepared is used in a method of forming electrically conducting silver tracks on enamel on glass windows, by applying to window glass an enamel composition containing the frit and on top thereof a silver composition in the shape of the tracks and firing the compositions, such that on the firing the reduced metal moiety reduces silver ions migrating through the enamel composition from the silver composition to elemental silver and thereby prevents or impairs them from interacting with the glass to form visible tracks.
