  • Monitoring of Hydrogen Sulfide in Industrial Processes

    Hydrogen sulfide, H2S, is a very poisonous, corrosive, and flammable gas. As such, it needs to be carefully monitored and controlled in industrial processes where it is generated or used. At relatively low concentrations, it has an odour of rotten eggs which effectively works as a warning, but at higher concentrations where it becomes acutely toxic and even lethal, it can no longer be smelled ...

  • An Easy Guide to Understanding Surfactants

    What is a Surfactant? Surfactants are a primary component of cleaning detergents. The word surfactant means surface active agent. As the name implies, surfactants stir up activity on the surface you are cleaning to help trap dirt and remove it from the surface. Surfactants have a hydrophobic (water-hating) tail and a hydrophilic (water-loving) head. The hydrophobic tail of each ...

  • Destruction of ozone depleting substances - Case study

    Destruction of ODSs ODSs are substances that cause the depletion of the ozone layer. Depletion is typically caused by the photo-dissociation of halocarbons and catalytic destruction of ozone by the resulting atomic halogens. The majority of these halocarbons are man-made and have such serious affects to the ozone requiring control synchronized by the Montreal Protocol. ...

  • Destruction of persistent organic pollutants - Case study

    Destruction of POPs POPs are molecules that persist in the environment due to their low degradability due to natural processes, and their characteristic of bio-accumulation. Due to their persistence, the bio-accumulation of these molecules over long periods of time causes hazardous effects on flora and fauna, and through the food chain, on human health. ...

  • Sustainability:What Does It Mean?

    The term sustainability is used more and more but there is a multitude of different definitions and applications for this term in the horticultural industry. Sustainability is defined as the “avoidance of the depletion of natural resources in order to maintain an ecological balance.” ...

  • A Dynamical Perspective on Atmospheric Temperature Variability and its Response to Climate Change

    The atmospheric temperature distribution is typically described by its mean and variance, while higher order moments, such as skewness, have received less attention. Skewness is a measure of the asymmetry between the positive and negative tails of the distribution, which has implications for extremes. It was recently shown that near-surface temperature in the southern hemisphere is positively ...
