  • Atomic Layer Etching – Changing the Art of the Possible

    The society of vacuum coaters (SVC) deserves to be better known. It was founded in 1957 during a surge in the use of vacuum coating techniques such as sputtering and evaporation. The techniques go back a very long way: that man Edison filed a patent for coating phonograph cylinders in 1892 (It will never catch on). Did you know that the shiny surface inside your crisp packet is a vacuum ...

  • Unconventional Pretreatment of Lignocellulose with Low-Temperature Plasma

    Abstract Lignocellulose represents a potential supply of sustainable feedstock for the production of biofuels and chemicals. There is, however, an important cost and efficiency challenge associated with the conversion of such lignocellulosics. Because its structure is complex and not prone to undergo chemical reactions very easily, chemical and mechanical pretreatments are usually necessary ...

  • Optimization of atmospheric air plasma for degradation of organic dyes in wastewater

    This study optimises the degradation of a cocktail of the dyes methyl orange and bromothymol blue by atmospheric air plasma. Response surface methodology (RSM) was employed to investigate the efficacy of the plasma process parameters on degradation efficiency. A Box–Behnken design (BBD) was employed to optimise the degradation of dyes by air plasma discharge. A second order polynomial equation ...

  • Nuclear Waste: Greatest environmental challenge facing society

    Dr Tim Johnson discusses how we can tackle the nuclear waste epidemic. A world full of waste They say you can tell a lot about a society by what it throws away. Like me, I’m sure you can recall the excitement of archaeologists on numerous TV documentaries, sifting through the remains of a rubbish dump or ‘midden’ on the edge of some ...

  • Let’s talk plasma

    Usually when I attend a conference on behalf of Tetronics I am about the average age of the other delegates. Not this time. Suddenly, I am old enough to be the father of most of the other people here, because this is a university-based conference hosted by the University of Liverpool. Yes, this is the snappily-titled International Workshop on Plasmas for Energy and Environmental Applications, or ...

  • Fly Ash Treatment – Plasma Torches versus Graphite Electrodes

    Background Plasma generating devices have to be designed to tolerate incredibly harsh conditions during operation and in particular very high heat loads and temperatures around the arc. However, when used in the vitrification of highly chlorinated materials the challenge is even greater than in other applications. The combination of high ...

  • 25 Years of Success – Outokumpu Stainless DC Plasma Smelting Facility

    Design is not just what is looks and feels like. Design is how it works. Between 1982 and 1987, British Steel (Outokumpu today) made extensive investigations into the treatment of steel dust. Their research was far and wide and covered off many various methods of recycling, including alternative to plasma technologies. But, in 1985, they engaged Tetronics International to carry out a ...

  • Phthalate degradation by glow discharge plasma enhanced with pyrite in aqueous solution

    In order to prevent health risk from potential exposures to phthalates, a glow discharge plasma (GDP) process was applied for phthalate degradation in aqueous solution. The results revealed that the phthalate derivatives 4-hydroxyphthalic acid, 4-methylphthalic acid and 4-tert-butylphthalic anhydride could be degraded efficiently in GDP process (498 V, 0.2 A) with high removal efficiencies of ...

  • Mitsubishi corporation - Spent Potliner (SPL) hazardous waste treatment - Case Study

    The Challenge Spent Potliner (SPL) is generated in the primary production of aluminium and worldwide is estimated to rise at a rate of over 500,000 tonnes per year. The SPL waste contains concentrations of cyanide and fluoride and gives off noxious and flammable gases when in contact with moisture. Unless carefully handled, these contaminants readily "leach" into the surrounding soils and ...

  • Duncan recyling & refining - Precious metal recovery from spent catalysts - Case Study

    The Challenge Spent catalysts contain Precious Metals, specifically the Platinum Group Metals (PGMs) that are valuable as a result of their low natural abundance, unique properties as well as the complex and costly processes that are required for their extraction/refining from primary sources. Duncan Refining and Recycling's (DR2) President, David Nichols, made the decision to ...

  • Reducing emissions via the use of electrical discharge techniques

    Abstract This report reviews the current use of electrical discharge techniques in air pollution control. The recent development of non-thermal plasma techniques in pollutant control technology has been driven by national and international legislation. Fundamental ideas behind this new technology are discussed and various methods of increasing the energy efficiency of the removal ...

  • Determining the viability of a waste-to-energy plant in Africa
