Article Synopsis
- The research investigated how well SiC ceramics can be soldered using a specific active solder (Sn5Sb3Ti) in a vacuum using electron beam heating.
- The solder has a narrow melting range and only one observed thermal behavior, with the solder becoming liquid at around 243 °C.
- Optimal soldering was achieved at 950 °C with a best wetting angle of 33°, and bonds formed between SiC and the solder due to reactions involving titanium and nickel, resulting in new phases that enhance bond strength, peaking at 40 MPa at 850 °C.
Objective: It is not yet clear how oxidative stress, free radicals, inflammatory cytokines and chemoattractants produced in the heart induce chronic heart failure. The myocardial damage caused by chronic diabetes results either from the persistence of inflammatory signaling directly in the heart or from the dysregulation of anti-inflammatory signaling systems. In the rat model of streptozotocin-induced diabetes (STZD) we investigated 1/ the concentration of free radicals (FR), 2/ reduced glutathione (GSH), 3/ lysozomal enzymes, 4/ inflammatory cytokines (tumor necrosis factor-? (TNF-?) and interleukin-6 (IL-6)), and monocyte chemoattractant protein-1 (mcp-1) in the myocardium.
