“…In the wall jet region, the turbulence between wall jet and surrounding air is transferred to the boundary layer of heat transfer surface; as a result the heat transfer efficiency in the wall jet region is higher than the efficiency in the parallel flow region. This leads to high cooling intensity and good cooling uniformity is obtained in the jet impingement cooling method [14][15][16] .…”

The new generation thermo-mechanical controlled processing (TMCP) technology based on advanced cooling technique and equipment is introduced here in the context of 960MPa grade high strength structural steel plates. This new technology accurately controls the cooling rate and temperature, with strong influence on phase transformation and precipitation including microstructure and mechanical properties of the steel. The application of the newly developed technology applied to the production of 960MPa grade high strength structural steel demonstrated its effectiveness, especially in improving low temperature impact toughness. The yield strength was 980~1000 MPa and tensile strength 1080~1200 MPa, with impact toughness approaching 150J at-40°C.Keywords: New generation TMCP technology; Ultra fast cooling process; high strength steels; mechanical properties

“…Therefore, it is crucial to develop a rapid method to detect Sudan dyes in foodstuffs for guaranteeing the safety of consumers. To date, a variety of analytical methods for Sudan dyes in foodstuffs have been proposed, mainly including high performance liquid chromatography (HPLC) (Sricharoen et al 2017), mass spectrometry (Mazzotti et al 2008;Sciuto et al 2017), raman spectroscopy (Cheung et al 2010;Anibal et al 2012;Ou et al 2017), chemiluminescence flow injection analysis (Liu et al 2007), molecular imprinting method (Xu et al 2014), electroanalytical technique (Ensafi et al 2012), enzyme-linked immune method (Haustein et al 2012;Wang et al 2012) and fluorescence method. Among them, fluorescence method has attracted great interests due to the simple instruments and easy operations.…”

Sudan dyes are phenyl-azoic derivatives widely used in industry. Classified as carcinogenic and are strictly forbidden in foodstuffs; however, some unscrupulous businessmen adopted it for coloring foodstuffs. Here, a simple and effective fluorescence (FL) assay platform has been developed for the detection of Sudan I-IV based on CsPbBr perovskite quantum dots (QDs). It was found that the fluorescent emission of CsPbBr QDs can be effectively quenched by Sudan I-IV. Under the optimized conditions, the FL quenching efficiency of CsPbBr QDs was quantitatively correlated to the logarithmic concentrations of Sudan I-IV over the ranges of 100-10,000, 0.1-1000, 0.1-2000 and 0.4-1000 ng mL for Sudan I-IV, and the corresponding limits of detection were 3.33, 0.03, 0.03 and 0.04 ng mL (at 3σ/slope), respectively. CsPbX QDs (X = Cl, Br, and I or mixed halide systems Cl/Br and Br/I) was utilized as sensor in FL assay, which have unique optical properties of high FL quantum yields (up to 90%), narrow half peak width (26 nm) and tunable FL emissions spectra (410-700 nm). Meanwhile, the practical use of this assay platform for Sudan I-IV detection in chilli powder samples was also demonstrated, which indicated the potential in practical applications.
