Porous metal oxides discs were used as moulds to produce low density microcellular disc shape foams. The oxide discs were produced by calcination of pressed hydroxide discs in vacuum at 500°C. The porous oxide discs were then impregnated with an app

Small, open‐ended, parylene microcylinders of 400 μm diameter, 700 μm length, and 10 μm wall thickness were filled with a solution of a polyfunctional monomer of low concentration. The solution was polymerised in situ with ultraviolet light to p

Hollow cylindrical fusion targets of 200–300 μm diam and 500–600 μm length, were fabricated and fitted at one end with a metallic ablator plate. The cylinders were then filled with a solution of polyfunctional acrylate monomer, which was subseq

Small, open ended, parylene cylinders of 150 μm diameter, 250 μm length and 10 μm wall thickness are manufactured and filled with solutions of acrylate monomers which are polymerised in situ with uv light to produce gels. These gels are then preci

The interaction of NO with chromia supported on AIPO4, phosphated alumina and alumina has been studied by infrared spectroscopy. Several different types of site have been identified for chromia on each support. The nature of the sites was strongly in

Spur reaction occurring in the radiolysis of cyclohexane and neopentane are discussed but the arguments apply to liquid aliphatic hydrocarbons in general. Because the most probable spur reactions lead to intermediates and products similar to those fo

The kinetics of ethene polymerisation over a series of chromia/silica–titania cogels have been studied. The catalysts were activated by reduction in CO at 623 K. Rates of polymerisation were first order in ethane pressure below 373 K. Above 373 K t

The influence on polyethene characteristics of titania incorporation into a Cr/silica catalyst, CO reduction and productivity has been investigated. Molecular weight (MW) and molecular-weight distribution (MWD) were dependent on all three variables:

Infrared spectroscopy has been used to study the adsorption of NO on a chromia/silica–titania cogel (4.2% Ti) reduced in carbon monoxide. A mononitrosyl surface complex gave a band at 1807 cm–1. Four types of dinitrosyl complexes have been identi

Nearly all work with O(1D) atoms has been conducted at room temperature. A system is described whereby photolysis of carbon dioxide at 163.3 nm may be used as a source of O(1D) atoms at a range of temperatures extending above 873 K.At 873 K the react
