    摘要: A molecular species is covalently attached to elemental carbon by exposing the carbon to a reaction mixture containing a strong base and a compound of the formula (I) or (II) in which X denotes a covalently attached atom or group capable of forming an X− anion and each Z is a moiety comprising a plurality of atoms, but which does not have a hydrogen atom directly attached to the atom which itself is directly attached to the —CH2X or —CHX group. The carbon substrate may be graphite or carbon nanotubes.

    摘要: Catalytic hydrogenation of a double bond, notably a C═C or C═N double bond, is carried out using a homogenous catalyst which is a complex of rhodium or other transition metal containing at least one ligand which is a nitrogenous organic base. Preferably the complex is phosphorus-free and the ligand is a bicyclic base having formula where R1 and R4 are hydrocarbon chains. R1 preferably is a saturated chain of two carbon atoms and R4 preferably is a saturated chain of three to five carbon atoms.

    摘要: In an arrangement for monitoring of flow within a hydrocarbon well or reservoir by means of one or more tracers which are placed at subterranean locations such that they may be present in flow produced from the well, the analysis of the flow produced from the well is carried out using an electrochemical method, preferably voltammetry, to detect tracer chosen to undergo a detectable electrochemical reaction. The tracer may be provided as nanoparticles in the well fluid.
