The development of alloyed quantum dot (QD) nanocrystals with attractive optical properties for a wide array of chemical and biological applications is a growing research field. In this work, size-tunable engineered band gap composition-dependent alloying and fixed-composition alloying were employed to fabricate new L-cysteine-capped alloyed quaternary CdZnTeS QDs exhibiting different internal ...

Controlling inclusion content in high chromium steel is very important to prevent submerged entry nozzle from clogging continuous casting and avoid the negative impacts of inclusions on properties. Therefore, effects temperature elements phase stability diagram should be clarified bearing steel. However, effect boundaries MgO, MgO∙Al2O3 Al2O3 are much different among researchers. The direction ...

In this study, we developed a novel eggshell based kappa-carrageenan-polyvinyl alcohol nanobiocomposite coated low alloyed steel foam. The prepared was preferred as coating function on the distribution of particles scanning electron microscopy (SEM), stereo microscope, and fourier transform infrared spectroscopy (FT-IR) techniques were used to determine chemical surface properties According cha...

Nitriding treatments of low alloyed steels can be performed only at relatively low temperatures in order to avoid a decrease of corrosion resistance due to nitride layers formation. These conditions promote the formation of the compound layer and diffusion zone, which shows high hardness and good corrosion resistance. In the present paper, the influence of the gas mixture N2-H2 in plasma nitrid...

Incidents in the Swedish railway have been observed where a significant and sudden loss of brake performance occurs winter conditions, on trains equipped with composite tread blocks (CBB). There is necessity to establish test methods that can be used for evaluation materials under well-controlled laboratory facilitate an understanding friction mechanisms between block steel wheel. This work sou...
