Nanowire lens can reconfigure its imaging properties

(PhysOrg.com) -- By taking advantage of the unique optical properties of nanoscale materials, researchers have designed a lens made of nanowires that can reconfigure its imaging properties without any electronic or mechanical ...

Nanochemistry in Action

(PhysOrg.com) -- Using a single-walled carbon nanotube (SWCNT) as a test tube, scientists can explore chemistry at the nanoscale, which involves some unique effects. Nanotubes provide a confined, one-dimensional space in ...

Researcher uses nanosilica to strengthen concrete (w/ video)

Every day, concrete structures crack and erode prematurely due to Alkali Silica Reactivity (ASR), a chemical reaction that causes fissures in the material as it sets. Jon Belkowitz, a doctoral student at Stevens Institute ...

The Nanotechnology of Sundew and English Ivy

Fifteen small sundew plants perch on a window sill, collecting sunlight and eating meat in the lab of Mingjun Zhang on the University of Tennessee's Knoxville campus. Sundew plants are carnivores, consuming insects by capturing ...

Shaping nanoparticles for improved quantum information technology

Particles that are mere nanometers in size are at the forefront of scientific research today. They come in many different shapes: rods, spheres, cubes, vesicles, S-shaped worms and even donut-like rings. What makes them worthy ...

Small optical force can budge nanoscale objects

(PhysOrg.com) -- Engineering researchers have used a very tiny beam of light with as little as 1 milliwatt of power to move a silicon structure up to 12 nanometers.
