With 100 trillion mechanical bonds per square centimeter, this molecular “chainmail” makes Kevlar-like materials ... them in a specific crystalline structure. After reacting these crystals ...

Forty years after scientists discovered methods for creating mechanical molecular bonds, experts have created a mechanically interlocked 2D material that’s much stronger than Kevlar. With 100 trillion ...

Next, they layered these sheets in a crystalline structure and coaxed the ends of all the X's to attach to each other through the introduction of a chemical ... similar to Kevlar that can resist ...

Kevlar derives its strength from molecular bonds in a 2D plane. But generally, the strongest materials tend to have a more complex 3D structure. For example, chainmail as a whole is much stronger than ...

The team positioned x-shaped monomers into a crystalline structure (a specific ordered arrangement) and reacted the crystals with another molecule ... the same family as Kevlar) and 2.5% of ...

They started with X-shaped monomers — which are the building blocks of polymers — and arranged them into a specific, highly ordered crystalline structure. Then, they reacted these crystals with ...

Machining composites is a dusty, arduous and abrasive process that is hard on cutting tools, requiring the right combination ...

The most broad, ASTM F2413 (previously ANSI Z41-1999) covers the minimum performance criteria for footwear designed to ...
