Using pressure to swell pores, not crush them

High pressure doesn't crush zeolites - it actually makes interior nanopores expand. Researchers show how 'super-hydration' inserts more water molecules into the cavities than can fit under ambient conditions.

New nanoscale imaging method finds application in plasmonics

Researchers have shown how to make nanoscale measurements of critical properties of plasmonic nanomaterials - the specially engineered nanostructures that modify the interaction of light and matter for a variety of applications, including sensors, cloaking (invisibility), photovoltaics and therapeutics.

Carbon nanotube broadband photodetector for polarized light

Using carpets of aligned carbon nanotubes, researchers from Rice University and Sandia National Laboratories have created a solid-state electronic device that is hardwired to detect polarized light across a broad swath of the visible and infrared spectrum.

First shape-memory plastics able to reverse deformation

Biomaterial researchers have developed plastics that can repeatedly change from one shape to another and then back again when temperatures fluctuate within a selected range. The material, dubbed 'polymer actuators' by its creators, thus overcomes a major limitation that affects similar materials.

Cancer nanotechnology: Nanoparticles with protein 'passports' evade immune system (w/video)

Scientists have found a way to sneak nanoparticles carrying tumor-fighting drugs past cells of the immune system, which would normally engulf the particles, preventing them from reaching their target. The technique takes advantage of the fact that all cells in the human body display a protein on their membranes that functions as a specific 'passport' in instructing immune cells not to attack them.

Taking the 'random' out of a random laser

Random Lasers are tiny structures emitting light irregularly into different directions. Scientists at the Vienna University of Technology have now shown that these exotic light sources can be accurately controlled.
