A Shatterproof Ceramic That Could Be Used To Make Lightweight Vehicles

A Shatterproof Ceramic That Could Be Used To Make Lightweight Vehicles 

 A tough ceramic’s structure mimics that of abalone shells.

Ceramics are lightweight and hard, but you can’t make jet engines out of them because they’d shatter like dinner plates. So, materials scientists have been trying to mimic natural materials that combine strength (a measure of resistance to deformation) with toughness (a measure of resistance to fracture). In particular, they’ve looked to the porous but resilient material called nacre that lines abalone shells. Now researchers have developed a method for manufacturing nacre-like materials in the lab. These new materials have mechanical properties similar to metal alloys and are the toughest ceramics ever made. The new method could lead the way to ceramic structural materials for energy-efficient buildings and lightweight but resilient automobile frames.

The Slicer – All Season Sled

The Slicer - All Season Sled 

 Featured Invention at the Colorado Inventor Showcase

For snow sledding, the SLICERTM works like any normal sled that is placed on a slope that is covered with snow or ice. But to slide down grass covered slopes, just the opposite is done: instead of putting the SLICERTM on the snow or ice, ice is put on the bottom of the SLICERTM!

 Mohonk Mountain House

It is probably a good thing that the Mohonk Mountain House, the 19th-century resort, was built on Shawangunk conglomerate, a concrete-hard quartz rock. Otherwise, the path to the National Weather Service’s cooperative station here surely would have turned to dust by now.
