Enhancing the strength of metals through microstructure engineering is of critical importance for the development of structural materials. The key factor that determines the strength of the metal is ...

Figure 1. This preoperative occlusal view shows a carious lesion on the mesioproximal surface of tooth #15. A Class II direct composite was chosen in this case to restore this area. Figure 2. Applying ...

Zero-thermal-expansion (ZTE) materials are widely used in precision optics, cryogenic equipment and sensors, where even small ...

Laminated fiber-reinforced composite materials are being used in more and more engineering applications. These materials have excellent strength-to-weight ratios and the manufacturing processes that ...

Good shade matching is tricky enough with porcelain. But a good shade match with composite materials can be an even bigger challenge. A new study has found that composite shades do not match well to ...

Inspired by hierarchical structures found in nature, a research team from the Hefei Institutes of Physical Science of the ...
