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.

One of the most common types of rock drilling tools is the drill bit, which is attached to a drilling rig and rotates to break through the rock surface. These bits are typically made of tungsten carbide or diamond, which are known for their hardness and durability. The design of the drill bit can vary depending on the type of rock being drilled and the specific requirements of the drilling operation. Carbide tipped drill bits are an essential tool for any construction or DIY project. These drill bits are designed to provide superior performance and durability compared to traditional steel drill bits. The carbide tip is a hard metal alloy made of tungsten and carbon that is welded or brazed onto the cutting edge of the bit. This carbide tip is what gives these drill bits their exceptional cutting ability and long-lasting sharpness.
