Effects of Shot Peening Pressure, Time, and Material on the Properties of Carburized Steel Shafts.

Carburized steel shafts are commonly used in industry due to their good wear resistance and fatigue life. If the surface of carburized shafts exhibits an undesired tensile stress, shot peening treatment may be required to alter the stress condition on the surface. In the present study, the effects of shot peening pressure (3-5 kg/cm), time (32-64 s), and material (stainless steel, carbon steel, and glass) on the residual stress, retained austenite, microhardness, and surface roughness of the carburized shafts were investigated.

Lipid Coated and Chlorin e6 Loaded Calcium Carbonate for Effective Immunotheraphy of Colorectal Cancer.

Cancer vaccine is well recognized as a novel but effective way for cancer immunotherapy. Especially, the role of dendritic cells (DCs) in antigen presentation properties is critical for the final performance of cancer vaccine. Herein, a lipid (Li) coated calcium carbonate (CC) vehicle (Li/CC) was employed to load chlorin e6 (Ce6) to serve as a potential vaccine (Li/CC-Ce6) for effective immunotherapy of colorectal cancer.
