  • Effects of gamma irradiation on PMMA/polyaniline nanofibre composites

    Polyaniline (PANI) presents promising antioxidant and radical-scavenging properties. Substances having these characteristics are good candidates for radioprotecting agents. In this work, nanofibres of polyaniline emeraldine doped with (?)-camphor-10-sulfonic acid (PANI-(?)-CSA) were prepared by self-assembly method under 'silent' and sonochemical conditions. PANI emeraldine base (PANI-EB) ...

  • Identification of forensic fabrics using a portable Raman spectrometer

    At a crime scene, a police officer collects a fiber sample that may prove to be invaluable evidence in identifying a criminal or exonerating an innocent person. While FTIR has been used for analysis in the past, the strong absorption of the fabric or the glass slide where it is mounted makes the spectrum very hard to interpret. In recent years, Raman spectroscopy has been studied extensively for ...

  • Soot level – a diesel engine lube oil condemning limit

    While there is widespread disagreement on used-diesel oil condemning limits, it is well known that excessive soot in the lube oil causes abnormal valve and injection-train wear.  It can also increase exhaust emissions and clog filters.  Typically, the suggested limit for soot is in the neighborhood of 3% but can go much higher.  With the new ASTM Method D7686, truck, bus, ...

  • Analysing four of the most contaminated foodstuffs

    Food adulteration has been around since the Victorian times when cheese was often coloured with lead salts, beer and milk were watered down and flour was bulked out with chalk dust or ground bones [1]. Governments apply stringent legislation and quality standards to food products but the practice of adulteration, driven by greed and profit, is still seen. ...

  • Sol-gel synthesis and catalytic performance of Ni-Co/Al 2 O 3 -MgO-ZrO 2 nanocatalyst with different ZrO 2 -loadings used in CH 4 /CO 2 reforming for hydrogen production

    A series of Ni-Co/Al 2 O 3 -MgO-ZrO 2 nanocatalysts with various ZrO 2 loadings were prepared via sol-gel method and used in CH 4 /CO 2 reforming. The nanocatalysts were characterised using XRD, FESEM, FTIR and BET analysis. The XRD patterns represented that by adding ZrO 2 to Ni-Co/Al 2 O 3 -MgO, the ...

  • Adsorption of malathion on thermally treated egg shell material

    Thermally treated egg shell materials were prepared at different temperatures. The samples were investigated by means of FT-IR and thermogravimetric analysis (TGA). The adsorption behaviour of malathion on egg shell and its thermally treated samples was studied using batch method and gave uptake capacities up to 0.964 mmol/g. Adsorption kinetics as well as the adsorption isotherms were discussed. ...

  • Fast, simultaneous and continuous monitoring of NOx and NH3 in DeNOx applications

    In DeNOx systems using urea injection with ammonia (NH3) as a reducing agent, the flow rate and control of NH3 must be continuously adjusted and controlled to prevent excess NH3 emissions (slip), to reduce environmental impact and cost of reagents. To optimize this process, it is essential to use an emissions analysis system for simultaneous and continuous monitoring of NOx and NH3. For preparing ...
