US scientists have developed the first examples of logic gates (NAND, NOR and XOR gates) that can be switched simply by bending the substrate.

Researchers at the University of Texas have fabricated biodegradable, nanobarcodes of silicon. The porosity of the silicon structures enables their applications in bioengineering, energy storage, and drug delivery systems.

Scientists in the USA have exploited all three dimensions of patterned photoresists, to make complex components using just one template.

Gallium arsenide is infiltrated for the first time within porous nanoparticle-based periodic multilayers to yield a new structure displaying finely tuned enhanced optical reflectance.
