    Ratiometric fluorometric and visual determination of cyanide based on the use of carbon dots and gold nanoclusters

    An optical method is described for the ratiometric fluorometric determination of cyanide ions. It is based on the use of a mixture of aqueous solutions of blue-emitting carbon dots (CDs) and red-emitting gold ...

    Ratiometric ultrasensitive fluorometric detection of ascorbic acid using a dually emitting CdSe@SiO2@CdTe quantum dot hybrid

    A dually emitting quantum dot nanohybrid was designed for the fluorometric 2-wavelength determination of ascorbic acid (AA). The nanohybrid consists of red-emitting CdTe quantum dots (QDs) covalently linked to...

    Influence of Process Parameters on Blistering during T6 Heat Treatment of Semi-Solid Castings

    High pressures applied to the castings during solidification mean that semi-solid castings tend to be prone to surface blistering during subsequent T6 heat treatment. It is believed that the blistering origina...

    Impact of Section Thickness on the Microstructure and Mechanical Properties of Semi-Solid Castings

    Slower cooling and solidification rates tend to increase both the grain size and dendrite arm spacings (DAS) of conventional castings. Both grain size and DAS impact strength and ductility, and so heavy sectio...

    Effects of samarium on microstructure and mechanical properties of Mg–Y–Sm–Zr alloys during thermo-mechanical treatments

    Microstructure and mechanical properties of Mg–4Y–xSm–0.5Zr (x = 1, 4, 8) alloys during thermo-mechanical treatments were investigated in this study. Mg–4Y–4Sm–0.5Zr alloy exhibits higher tensile strength but low...
