is a toxic metal that is harmful to the environment and human health. To reduce environmental pollution and protect workers' health, many countries and regions have enacted regulations to restrict or ban the use of lead-containing solder. This has prompted the development and use of this material...
material than lead solder, the expansion of silicone, when it heats up, does not disrupt the electrical connection between the component and the substrate. Another advantage of using conductive silicone is that it does not create electric flux, which must be cleaned from traditional solder. ...
The proton flux was initiated by an alkaline pH shift from рН 6 to рН 8, which was caused by the addition of the previously determined aliquot of KOH. In the presence of the protonophores, the pyranine fluorescence gradually increased, indicating the alignment of the pH values inside ...
Both viability assays demonstrated that the toxic effect of ricin on cell viability was increased in the autophagy-deficient shATG5 cells (3.74 ± 0.55-fold, * p < 0.05, n = 4; 3.00 ± 0.33-fold, * p < 0.05, n = 3) compared with the shNT control cells (Figure 2E–G). Altogether...
During the soldering process, the solder flux can eliminate oxidation. However, this situation does not affect soldering performance; hence, no measures are necessary to prevent this situation. In contrast, if the flux cannot eliminate oxidation, it would affect soldering performance. As such, some...
Solder joint too close to root? The spot welding voltage is too high, and the tantalum wire is too melted? b) Is the tantalum wire dirty? Is the silicone not coated properly? Silicone on the top? Is the reinforcement layer on the upper end surface too thin? The frame size does not ...
Depression is a disease with several molecular mechanisms involved, such as problems in the serotonergic pathway. This disease is very complex and prevalent, and thus important to deeply study and aim to overcome high rates of relapse and therapeutic fai
