Transportation, housing, clothing, communication, recreation, and food production virtually every segment of our everyday lives is influenced to one degree or another by materials. Historically, the development and advancement of socities have been intimately tied to the members's ability to produce and manipulate m…
Multifunctional scaffolds based on smart materials have been applied in different tissue engineering fields. The most frequently studied areas in the literature include the use of multifunctional scaffolds in bone, cartilage and muscle formation, in cardiovascular and endothelium tissue engineering, in the growth of skin and in neural regeneration. Other applications include their use in dental…
All robust seals are characterized by the absence of any pathway by which fluid or gas might escape. Detail differences exist in the manner by which zero clearance is obtained — welding, brazing, soldering, ground fits or lapped finishes — or the yielding of a softer material wholly or partially confined between two harder and stiffer members of the assembly. The O-ring seal falls in the la…
