compression deformation treatment, the studied in-situ TiB2/7075Al composite has finer grain size. This is mainly attributed to the ultrafine in-situ particles in the composite, which are able......
(Figure 7(d′)). Studies have found that receptor-ligand mediation can improve the ability of target cells to take in nanoparticles and improve the ability of intraparticle biochemical treatment......
is surface treatment. There are many kinds of common anti- corrosion coatings, including chemical conversion coatings [17], micro-arc oxidation (MAO) [18,19], anodic oxidation [20-22], polymer films......
under magnetic stirring for 24 h at room temperature. The pH value was adjusted from 6.0 to 10.0 by adding 0.1-0.6 mL 25% ammonia. The solution was heat-treated at 50 °C and then powdered at 80 °C....jclepro.2020.124291. [9] ABD-ELAAL E S, ARABY S, MILLS JULIE E, YOUSSF O, ROYCHAND R, MA Xing, ZHUGE Yan, GRAVINA REBECCA J.
