Characterisation of Acid Resistant Concrete Exposed to Sulphuric Acid Using SEM, EDS and X-Ray Mapping

X-Ray Mapping Using Multiple-EDS and WDS Detectors

High quality x-ray mapping (XRM) has been used for over 30 years by experienced wavelength dispersive spectroscopy (WDS) operators. Manufacturers have been developing similar techniques using energy dispersive spectroscopy (EDS) over the last 20 years. This has been generally unsuccessful due to a number of problems such as poor computer specifications, cost, time to map and generally poor peak...

Sulphuric Acid in Cholera

can only be properly prescribed by the medical attendant. There is no single antidote. As a valuable adjunct against the epidemic the following orangeade, suggested by Dr. Waller Lewis, has been extensively used with excellent effects :? " Sulphuric Orangeade useful in Cholera times.?Concentrated compound infusion of orange peel 3 oz., simple syrup 12 oz., boiled filtered water 4 gallons, mix w...

An evolutionary approach to modelling concrete degradation due to sulphuric acid attack

Sickness absence and ventilatory capacity of workers exposed to sulphuric acid mist.

Williams, M. K. (1970). Brit. J. industr. Med., 27, 61-66. Sickness absence and ventilatory capacity of workers exposed to sulphuric acid mist. The certified sickness absence and ventilatory capacity of men exposed to high concentrations of sulphuric acid mist in the Forming department of an electric accumulator factory, and in control departments, were investigated. The Forming men showed a sl...

Sem/eds Theoretical Stuff

Silicone based oil is heated in the boiler of the diffusion pump and the vaporized oil rises in the central tower and streams out of directional flutes directed downward in the pump throat. This allows air molecules to dissolve in the gaseous oil (gas dissolved in gas). As the oil-air mixture cools (due to water cooling coils wrapped around the pump throat) the oil condenses and returns to liqu...
