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.

Protein design is a technique that is increasingly valuable to a variety of fields, from biochemistry, to therapeutics, to materials engineering. University of Pennsylvania chemists have taken this kind of design a step further; using computational methods, they have created the first custom-designed protein crystal.

Scientists
at the National Center for Electron Microscopy have created the
first-ever atomic-scale real-time movie of nanocrystal growth in liquid.
The movie, which shows nanoparticles of platinum diffusing in liquid
then coalescing into crystals, was made possible with TEAM I, the
world’s most powerful microscope.

Glass,
one of the oldest man-made materials, is a non-crystalline amorphous
material produced by the fusion of crystalline powder mixtures heated to
high temperatures Using high-energy X-rays, scientists have for the
first time visualized the transformation of powder mixtures into molten
glass.

Naturally-occurring
gypsum is an important industrial mineral used in buildings, artwork,
casts, and fireproofing. But until now the process of how gypsum
crystals form has never been documented. Findings by scientists in the
U.K. may point to a way of creating low-cost, low-temperature gypsum in
the laboratory.

An international team of researchers has discovered a new type of structural anomaly, or defect, that can appear in quasicrystals, a unique material with some crystal-like properties but a more complex structure.

Scientists at the University of Southampton, in collaboration with Penn State University have, for the first time, embedded the high level of performance normally associated with chip-based semiconductors into an optical fiber, creating high-speed optoelectronic function.

A University of Arkansas physicist and his colleagues have examined the challenges facing scientists building the next generation of materials and innovative electronic devices and identified opportunities for taking the rational material design in new directions.

Custom modifications of equipment are an honored tradition of the research laboratory. In a recent paper, two materials scientists at NIST describe how a relatively simple mod of a standard scanning electron microscope enables a roughly 10-fold improvement in its ability to measure the crystal structure of nanoparticles and extremely thin films.

Purdue
University physicists
created computational tools that can predict the fleeting structures of
iron-containing enzymes as they transform during chemical reactions.
Many of
these temporary but critical structures have eluded capture through
traditional
experimental methods such as X-ray crystallography.
