Nanoscale spheres allow low-cost creation of 3-D nanostructures

Researchers have developed a new lithography technique that uses nanoscale spheres to create three-dimensional (3-D) structures with biomedical, electronic and photonic applications. The new technique is significantly less expensive than conventional methods and does not rely on stacking two-dimensional patterns to create 3-D structures.

Atomic 'mismatch' creates nano 'dumbbells'

Researchers are closer to understanding the process by which nanoparticles made of more than one material - called heterostructured nanoparticles - form. This process, known as heterogeneous nucleation, is the same mechanism by which beads of condensation form on a windowpane.

Light propagation in solar cells made visible

How can light which has been captured in a solar cell be examined in experiments? Scientists have succeeded in looking directly at light propagation within a solar cell by using a trick. The photovoltaics researchers are working on periodic nanostructures that efficiently capture a portion of sunlight which is normally only poorly absorbed.

Filming chemistry with a high speed x-ray camera

A chemical reaction is a rearrangement of atoms in and between molecules, the breaking of old and the formation of new bonds. The glue that binds atoms in molecules and creates the bonds between them is made out of valence electrons. Scientists were able to show theoretically that the ultrafast x-ray camera is not only sensitive to inert core electrons but may also visualize the motion of chemically active valence electrons.

Smallest possible diamonds form ultra-thin nanothreads

For the first time, scientists have discovered how to produce ultra-thin diamond nanothreads that promise extraordinary properties, including strength and stiffness greater than that of today's strongest nanotubes and polymers.
