Bulk metallic glasses can be as strong or even stronger than steel, as malleable as plastics, conduct electricity and resist corrosion. These materials would seem to have it all save for one problem: they are often brittle, with a poor and uneven resistance to fatigue that makes their reliability questionable. The creation of multicomponent bulk-metallic glass composites is addressing this issue but the problem remains for monolithic metallic glasses, which are major components of bulk metallic composites.
A new study evaluates the effect of incorporation of an acrylate polyhedral oligomeric silsesquioxane nanostructure (APOSS) on the physical and mechanical properties and hydrolytic stability of octyl cyanoacrylate adhesives.
Researchers have created tiny holograms using a 'metasurface' capable of the ultra-efficient control of light, representing a potential new technology for advanced sensors, high-resolution displays and information processing.
Stanford University scientists have created a silicon-based water splitter that is both low-cost and corrosion-free. The novel device - a silicon semiconductor coated in an ultrathin layer of nickel - could help pave the way for large-scale production of clean hydrogen fuel from sunlight, according to the scientists.
A center to discover what new properties can be created when atom-thick 2-dimensional layers of elemental materials and chemical compounds are formed or when those layers are built up into completely new 3-dimensional structures has opened.
When you squeeze atoms, you don't get atom juice. You get magnets. According to a new theory by Rice University scientists, imperfections in certain two-dimensional materials create the conditions by which nanoscale magnetic fields arise.
