When fungi, such as penicillium, grow, they form a thread-like network, the mycelium. If the fungus is grown in a medium containing nanoscopic particles of a noble metal, the resulting mycelium is coated with the nanoparticles.
Research at Purdue University suggests synthetic carbon molecules called fullerenes, or buckyballs, have a high potential of being accumulated in animal tissue, but the molecules also appear to break down in sunlight, perhaps reducing their possible environmental dangers.
Following independent paths of investigation, two research teams are announcing this month that they have successfully converted sugar-potentially derived from agricultural waste and non-food plants-into gasoline, diesel, jet fuel and a range of other valuable chemicals.
Scientists at JILA, a joint institute of the National Institute of Standards and Technology (NIST)and the University of Colorado at Boulder (CU-Boulder), have applied their expertise in ultracold atoms and lasers to produce the first high-density gas of ultracold molecules - two different atoms bonded together - that are both stable and capable of strong interactions.
Researchers from Asia, Australia and Europe will join U.S. scientists and government officials to discuss nanotechnology applications for environmental cleanup, pollution control and the implications of releasing engineered nanoparticles into the environment.
To ensure nanotechnology is developed in a responsible manner, the National Science Foundation (NSF) and EPA awarded $38 million to establish two Centers for the Environmental Implications of Nanotechnology (CEINs).
A brief clinical report showed that Contrast-enhanced intraoperative ultrasonography (CE-IOUS) using a new microbubble agent, Sonazoid, can allow surgeons to investigate the whole liver with enough time and to find new metastases intraoperatively.
The centers, led by UCLA and Duke University, will study how nanomaterials interact with the environment and with living systems, and will translate this knowledge into risk assessment and mitigation strategies useful in the development of nanotechnology.
A two-year grant is allowing researchers at UCR?s Bourns College of Engineering to unlock the secrets behind the enormous strength of the inner pearly layer (nacre) of the abalone shell so it can be replicated in man-made materials.
Someday, your car might have the metallic finish of some insects or the deep black of a butterfly's wing, and the reflectors might be patterned on the nanostructure of a fly's eyes, according to Penn State researchers who have developed a method to rapidly and inexpensively copy biological surface structures.
Light hitting a surface creates very different kinds of disturbances depending on whether it's a metal or a semiconductor. But combining these two materials in a single nanostructure could lead to devices that benefit from the best properties of each.
