Nanotechnologists Specify Limitation For Devising Small Machines

...gthens depending on its distance from a surface, an idea first proposed by pioneering quantum physicists in the late 1920s. The measurement tells nanotechnologists how small they can make extremely tiny devices before a microscopic force between atoms and surfaces, called van der Waals interaction, becomes a conc...

Air-purifying church windows early nanotechnology

...overed. Associate Professor Zhu Huai Yong, from QUT's School of Physical and Chemical Sciences said that glaziers in medieval forges were the first nanotechnologists who produced colours with gold nanoparticles of different sizes. Professor Zhu said numerous church windows across Europe were decorated with glas...

Guilt on their hands: tiny 'tags' could help to solve and deter gun crime

... increase in successful convictions. This breakthrough has been achieved by a team of chemists, engineers, management scientists, sociologists and nanotechnologists from Brighton, Brunel, Cranfield, Surrey and York Universities, with funding from the Engineering and Physical Sciences Research Council (EPSRC). ...

Technique controls nanoparticle size, makes large numbers

... of study. One area is nanotoxicology, which researches the health and environmental safety of new materials containing nanoparticles. To test safety, nanotechnologists join forces with biologists to determine the safety of different-sized particles. For example, one size particle may provide the best effects in a cos...

Homing pigeons get their bearings from their beaks

...these minute iron oxide crystals goes farther than their amazing ability to help pigeons home. Research into how they work has caught the interest of nanotechnologists concerning their potential application for accurate drug targeting and even as a data storage device. The main problem, however, lies in their synthe...

UCLA researchers unravel a mystery about DNA

... right." "The study of molecular machines, the dynamics of their moving parts and their translocation on molecular tracks is of great interest to nanotechnologists at the CNSI," said Weiss, the leader of the UCLA team. "Beyond furthering the understanding of transcription regulation, the novel methods and finding...

Wisconsin scientists find a way to make human collagen in the lab

...he context of nanotechnology, collagen has appeal as a type of nanowire because it is thin -- thinner even than the vaunted carbon nanotubes hailed by nanotechnologists -- and long. Coated with gold or silver, human collagen could form the basis of implantable electric sensors. By attaching certain biological molec...

Nanotechnologists gain powerful new materials probe

... be able to get detailed information about magnetic interactions even from a nano-structured thin film sample. These are the sort of interactions that nanotechnologists are trying to take advantage of when they design and shape things at the nanoscale. ...

Using living cells as nanotechnology factories

...king copies of double stranded DNA and we have used the cell like a copier machine to produce many, many copies of complex DNA nanostructures." DNA nanotechnologists have made some very exciting achievements during the past five to 10 years. But DNA nanotechnology has been limited by the need to chemically synthesi...

Microscopic 'clutch' puts flagellum in neutral

... effective. We think the clutch prevents the flagellum from rotating when constrained by the sticky matrix of the biofilm." The discovery may give nanotechnologists ideas about how to regulate tiny engines of their own creation. The flagellum is one of nature's smallest and most powerful motors -- ones like those ...

Dude, big screen TVs, flexible electronics and surfboards made from same new material!

...e marine industry for decades and the construction industry is built on reinforced concrete. Now carbon nanotubes (CNT) are getting in on the act with nanotechnologists working out how to grow nanotube reinforcements for polymers in an ideal manner. Researchers from Trinity College have developed a scalable inexpen...
