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 in improved buildings for the future.
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 constructed at the molecular level. Steady progress is being made on understanding how and if these goals can be achieved.
