Materials made from particles one-millionth the size of a fine-point pen tip are touted daily for their current uses and dreamed of possibilities, but a pressing question remains as to the environmental impact of manufactured nano-sized materials.
Purdue University scientists are investigating the interactions between these tiny, many-sided structures and the environment. To further this research, the National Science Foundation (NSF) and Environmental Protection Agency (EPA) have awarded grants totaling nearly $2 million to the Purdue Nanoscale Interdisciplinary Research Team and a colleague from the University of Minnesota.
"This is one of the first major studies solely interested in the environmental fate of carbon-based manufactured nanoparticles," said Purdues Ron Turco, principal investigator on the project. "We will test Buckyballs and other manufactured nanomaterials in all types of soil and in water to determine their effect on the environment, including any toxicity toward bacteria and fungi that are key indicators of damage to the ecosystem."

Using an ultra fast-scanning atomic force microscope, a team of researchers from the University of Basel has filmed “living” nuclear pore complexes at work for the first time. Nuclear pores are molecular machines that control the traffic entering or exiting the cell nucleus. In their article published in Nature Nanotechnology, the researchers explain how the passage of unwanted molecules is prevented by rapidly moving molecular “tentacles” inside the pore.

If a person pushes a broken-down car alone, there is a certain effect. If another person helps, the result is the sum of their efforts. If two micro-particles are pushing another microparticle, however, the resulting effect may not necessarily be the sum their efforts. A recent study published in Nature Communications, measured this odd effect that scientists call “many body.”
In the microscopic world, where the modern miniaturized machines at the new frontiers of technology operate, as long as we are in the presence of two...
Researchers from the Max Planck Institute Stuttgart have developed self-propelled tiny ‘microbots’ that can remove lead or organic pollution from contaminated water.
Working with colleagues in Barcelona and Singapore, Samuel Sánchez’s group used graphene oxide to make their microscale motors, which are able to adsorb lead...
Neutron scattering and computational modeling have revealed unique and unexpected behavior of water molecules under extreme confinement that is unmatched by any known gas, liquid or solid states.
In a paper published in Physical Review Letters, researchers at the Department of Energy's Oak Ridge National Laboratory describe a new tunneling state of...
