The findings of the three-phase project was published in its capstone Innovation Impact Report. The study was launched in February 2010 when TMS convened an Energy Materials Blue Ribbon Panel, consisting of 21 thought leaders in materials science and engineering.
The silk that spiders use to build their webs, trap their prey and dangle from your ceiling is one of the strongest materials known. But it turns out it’s not simply the material’s exceptional strength that makes spider webs so resilient; it’s the material’s unusual combination of strength and stretchiness — silk’s characteristic way of first softening and then stiffening when pulled.
These properties, scientists have found, vary depending on the forces applied, as well as on the overall design of the web.
Markus Buehler, an associate professor of civil and environmental engineering (CEE) at MIT, has previously analyzed the complex, hierarchical structure of spider silk and its amazing strength — on a pound-for-pound basis, it’s stronger than steel. Now,
It is not a fairy tale! The prefabricated building , the five-star T30 Hotel at Dongting lake, Hunan province became an internet sensation after time-lapse video posted online showed it being constructed by 200 builders in just 360 hours.
