Nanoparticles at fluid interfaces are central to a rapidly increasing range of cutting-edge applications, including drug delivery, uptake through biological membranes, emulsion stabilization and the fabrication of nanocomposites. Understanding nanoscale wetting is a challenging issue, still unresolved for individual nanoparticles, and is essential in designing nanoparticle-building blocks with ...

Pouring temperature also affects the mechanical properties of aluminium. High pouring will make aluminium grains become large and a lot gas be trapped into liquid metal when is poured mould. The right prevent porosity does not freeze before filling entire moulds cavity. casting process used permanent Temperature was 150 °C pressure 0.35 atm (absolute pressure). were 750, 800 850 °C. increasing ...

Background Since the treatments of long tracheal lesions are associated with some limitations, tissue engineered trachea is considered as an alternative option. This study aimed at preparing a composite scaffold, based on natural and synthetic materials for tracheal tissue engineering. Methods Nine chitosan silk-based scaffolds were fabricated using three freezing rates (0.5, 1, and 2°C/min) ...

Manufacturing processes yielding stronger, yet lighter structures are sought for in many industries and scientific applications. Freeze casting is a fabrication process that offers way to achieve these strong, lightweight structures, but only single direction (the of the templating-ice growth). Applying uniform magnetic field allows increased strength an additional direction, thus allowing them...
