What it is:A super-thin material created by researchers atRice Universityand MITcan stop a fast-moving projectile, such as a bullet, in its path. The material, made from alternating rubber and glassy layers that are each just 20 nanometers thick, is good at dispersing energy. Afterbeing pe...
Carbon nanotubes are a large family of carbon-based hollow cylindrical structures with unique physicochemical properties that have motivated research for diverse applications; some have reached commercialization. Recent actions in the European Union that propose to ban this entire class of materials highlig...
Hydrogels are flexible materials that have high potential for use in various applications due to their unique properties. However, their applications are greatly restricted by the low mechanical performance caused by high water content and inhomogeneous networks. This paper reports a universal strategy fo...
Materials, products, and construction systems are constantly evolving and following new technologies, discoveries, and market trends. How should we use materials—both in their traditional forms and in their future conceptions—so that our projects are m
Polymers include the familiar plastic and rubber materials. Many of them are organic compoundsthat are chemically based on carbon, hydrogen, and other nonmetallic elements; furthermore, they have very large molecular structures. These materials typically have low densities and may be extremely flexible...
The present invention provides solid wood paneling formed of beveled, solid wood planks having a uniform, standardized length. At least some of these planks are made up of shorter, random length boards that have been joined into longer, ... RA Hanson - US 被引量: 153发表: 1992年 Measuremen...
4f). The gears are made of aluminium alloy (Supplementary Fig. 17). Shear tests on the prototype give a tiny modulus of G = 21.52 kPa. Independent measurement of the frames gives Gf = 21.11 kPa, so that Gg = G – Gf is indeed negligibly small. Moreover, ...
