Nanowires could lead to improved solar cells

With an increased focus on alternative sources of cheap, abundant, clean energy, solar cells are receiving lots of attention. The dye sensitized solar cell (DSSC) is one of the most important developments in photovoltaics in the last two decades. Researchers are now on the brink of improving the efficiency of DSSC through nanowires.

Making Nanotube TVs happen

Researchers have turned to carbon nanotubes to create a new class of large area, high resolution, low cost flat panel displays. Some believe field emission display (FED) technology, utilizing carbon nanotubes (CNT) as electron emitter, will be the biggest threat to LCD's dominance in the panel display arena.

Nanoparticle-stabilized liposomes

Liposomes, man-made cells used as drug delivery vehicles, would be more useful if only they could be stabilized against fusion with one another. Researchers at the University of Illinois told Nanowerk that they succeeded in doing exactly that - they stabilized phospholipid liposomes with charged nanoparticles, thereby opening up interesting functional perspectives.

Nanoscale magnetic materials are a key focus in developing biomedical applications

Spanish researchers developed a simple and inexpensive way to produce well-coated iron nanoparticles. The particles thus obtained present a much stronger magnetic response than any composite material produced up to now involving magnetic nanoparticles encapsulated in inorganic matrices, and the rich chemistry and easy functionalization of the silica outer surface make them promising materials for their application as magnetic carriers.
