Building shapes are making exciting departures from the rectilinear boxes that have dominated in architectural history, leading people to draw similes with the natural world. But there is the potential for architects to learn more deeply from nature, and use biomimetic materials and technologies...
Nanoparticles are commonly thought to be the fundamental building blocks for new devices. Spontaneous assembly of ordered chemically distinct subnanometre domains on the surface of gold nanoparticles may reduce the size of the fundamental building block even further.
Clever microfluidic plumbers show us how biological processing at the nanolitre scale really only requires micromachining technology. The pico era may not be so far off.
A composite membrane in which the nanoscopic pores of a material are aligned within the larger pores of a matrix brings us a step closer to the realization of molecular filters.
To some researchers, the goal of molecular electronics is to develop cheaper and higher-performance alternatives to conventional silicon-based technology. To others, it is the exploration of entirely new possibilities opened up by the different properties and phenomena exhibited by devices...
The surface energy of a solid measures the energy cost of increasing the surface area. All normal solids therefore have a positive surface energy
—if it had been negative, the solid would disintegrate. For this reason it is also generally believed that when certain ceramics can be found in a...
There has been considerable interest in the synthesis of new nitrides because of their technological and fundamental importance
. Although numerous metals react with nitrogen there are no known binary nitrides of the noble metals. We report the discovery and characterization of platinum...
