Lawrence Berkeley National Laboratory researchers have reported the first direct observation of nanoparticles undergoing oriented attachment, the critical step in biomineralization and the growth of nanocrystals. A better understanding of oriented attachment in nanoparticles is a key to synthesizing new materials with remarkable structural properties.

The
contention of a major but controversial new theory to explain
nanocrystal growth is that nanoparticles can act as “artificial atoms,”
forming molecular-type building blocks that can assemble into complex
structures. The conclusion is based on recent observations of growing
nanorods made by Lawrence Berkeley National Laoratory researchers using
transmission electron microscopy and advanced liquid cell handling
techniques.

The scientific and technological literature is abuzz with nanotechnology
and its manufacturing and medical applications. But it is in an area
with a
less glitzy aura—plant sciences—where nanotechnology advancements are
contributing dramatically to agriculture. Researchers at Iowa
State University
have now demonstrated the ability to deliver proteins and DNA into plant
cells,
simultaneously.

Ion bombardment of metal surfaces is an important, but poorly understood, nanomanufacturing technique. New research using sophisticated supercomputer simulations has shown what goes on in trillionths of a second. The advance could lead to better ways to predict the phenomenon and more uses of the technique to make new nanoscale products.

A
year-long evaluation of the effect of quantum dots in primates has
found the nanoparticles to be safe, encouraging doctors and scientists
who are hoping to use them to battle diseases like cancer. Cadmium
selenide quantum dots were the variety used in the study.

University
at Buffalo researchers are making significant progress on rust-proofing
steel using a graphene-based composite that could serve as a nontoxic
alternative to coatings that contain hexavalent chromium, a probable
carcinogen.

Joshua
Zide has spent nearly a decade engineering nanomaterials using
molecular beam epitaxy. His particular area of expertise are
metalllic-semiconductor nanocomposite for use in electronics, and he is
now working on a variation of epitaxy that he hopes will bring the
materials deposition technique to the production line for the first
time.
