Solid-state proteins maximize the intensity of fluorescent-protein-based lasers

The same research team that developed the first laser based on a living cell has shown that use of fluorescent proteins in a solid form rather than in solution greatly increases the intensity of light produced, an accomplishment that takes advantage of natural protein structures surrounding the light-emitting portions of the protein molecules.

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.
