Article Synopsis
- The study explores the antibacterial effects of tantalum-copper (Ta-Cu) coatings on titanium alloys to combat infections from orthopedic and dental implants.
- The coatings were created with different copper percentages and subjected to various thermal treatments, with the TaCu-2 sample (∼10 wt% copper, annealed at 600 °C) showing the best antibacterial performance.
- Optimizing the copper content and annealing temperature was found to be crucial in improving the antibacterial properties of these coatings, suggesting their potential for reducing implant-related infections.
The problem of synchronization in networks of linear systems with nonlinear diffusive coupling and a connected undirected graph is studied. By means of a coordinate transformation, the system is reduced to the form of mean-field dynamics and a synchronization-error system. The network synchronization conditions are established based on the stability conditions of the synchronization-error system obtained using the circle criterion, and the results are used to derive the condition for synchronization in a network of neural-mass-model populations with a connected undirected graph.
