- Firstly, the strength-to-weight ratio of fiberglass is unparalleled. Despite being lightweight, these tanks can withstand immense pressure and loads, making them suitable for storing heavy liquids or substances under high pressure. Their robust structure allows them to endure extreme weather conditions, corrosion, and physical impacts without degrading or leaking, ensuring a safe and secure storage solution.
- Furthermore, the group shell dictates the type of bonds an element can form
- One of the key advantages of using button bits for rock drilling is their ability to maintain their sharpness and cutting performance over an extended period of time. This is due to the hardness and wear resistance of the tungsten carbide buttons, which helps to minimize the need for frequent bit changes and maintenance.








Inspired by the flexibility and rigidity of natural spider silks webs, a research team led by Prof. YU Shuhong from the University of Science and Technology of China (USTC) developed a simple and general method to fabricate superelastic and fatigue resistant hard carbon aerogels with nanofibrous network structure by using resorcinol-formaldehyde resin as a hard carbon source.
