“…Some of the former grow into larger growth centres near the edges of the films (figures 3-5). They are different from the wheel-shaped or dendritic growth centres (Boggs et al 1961b;Muneera et al 1983) observed on films exposed to normal atmospheres (figures 9-10). Figure 6 shows the larger growth centre along with the other nucleation centres.…”

The oxidation of thin films of tin at room temperature in an atmosphere containing 10 ~, H2S and 900~o air has been studied by measuring the changes in resistance of thin films. Morphological studies have also been carried out using optical and scanning electron microscopes. Reaction kinetics change from logarithmic law at ordinary atmospheres to a power law in the presence of H2S. The basis of formation of sulphidemlong with the oxide is explained, the former growing on a lower layer and the latter on an upper layer.

“…After measuring the resistances, the films coated in the same pump-down were quickly transferred to an enclosed glass chamber (Muneera et al 1983) evacuated to a pressure of 10-2 Torr. The required amount of air was then admitted into the chamber followed by 10 o/jo by volume of dry H2S stored in a reservoir.…”

“…Metals such as tin (Muneera et al. ) have been shown to oxidise SO 2 in the presence of O 2 to sulfate but when the partial pressure of SO 2 is greater than that of O 2 , the metal reduces SO 2 to sulfide. In bottled wine, the available oxygen from migration through the closure is highly dependent on the closure type (Godden et al.…”

Undesirable volatile sulfur compounds with aromas, such as boiled or rotten egg, sewage and rubber, can impact negatively on wine sensory attributes. The identity of these molecules is known but knowledge gaps exist about their source and ways to manage them in winemaking. This review focuses on the chemistry of the three main compounds: hydrogen sulfide, methanethiol and dimethylsulfide. Discussion centres on their possible origins and the efficacy of methods currently used to control them during wine production. The role of metals, both in the vineyard and in the winery, in the formation and release of these three volatile sulfur compounds is described. Oxygen management during fermentation and bulk ageing is discussed along with the impact of the bottle closure.
