Aluminium composites have been extensively developed for automotive applications due to their high specific strength. However, particle agglomeration, porosity content, and weak reinforcement/matrix interface bond are prone occur in the casting process. These arise during introduction of reinforcement, mould filling, solidification process, especially when sizes approaching nanoscale detrimenta...
Pure aluminium poses inferior properties that limit its use in load-bearing applications. Reinforcing multiwall carbon nano-tube (solid lubricant) and graphene to matrix offers better (antifriction, hardness, wear resistance) composites for such A stir casting processing route is employed prepare the hybrid composite (aluminium-multiwall nanotube-graphene Al-MWCNT-GR). The Taguchi L16 experimen...
PURPOSE To evaluate the role of short-inversion-time inversion-recovery (STIR) sequences in assessment of brain maturation. METHODS Twenty-seven infants and young children with normal neurologic development were examined by 1.5-T MR using a circularly polarized head coil. Axial T1-weighted and T2-weighted and spin-echo and STIR images were obtained. Signal intensity of different anatomic stru...
Euphorbia kansui is a Traditional Chinese Medicine widely used for the treatment of oedema, ascites and asthma. However, its serious hepatotoxicity hinders its safe clinical application. The process of stir-baking with vinegar is regularly used to reduce the toxicity of kansui. Up till now, the exact mechanism of the reduction in hepatotoxicity of kansui stir-baked with vinegar has been poorly ...
