Advice on the use of carbon nanotubes from a new research study Which is better, a quick vertical jab on the buttock or the delicately soft entry of a blood sample? Waiting to find out "for what", some are already wondering "how" to use those tiny "molecular syringes" which are carbon nanotubes. With a diameter of less than one millionth of a millimeter (nanometer) and a maximum length of just a few millimeters, the first use that springs to mind when we think of this ethereal tubes - the...

Berkeley Lab Researchers Find New Way to Mass Produce High Quality Boron Nitride Nanoribbons For Hollywood celebrities, the term "splitsville" usually means "check your prenup." For scientists wanting to mass-produce high quality nanoribbons from boron nitride nanotubes, "splitsville" could mean "happily ever after." Scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley, working with scientists at Rice University, have...

Scientists at Northern Illinois University say they have discovered a simple method for producing high yields of graphene, a highly touted carbon nanostructure that some believe could replace silicon as the technological fabric of the future. The focus of intense scientific research in recent years, graphene is a two-dimensional material, comprised of a single layer of carbon atoms arranged in a hexagonal lattice. It is the strongest material ever measured and has other remarkable qualities,...

The July Issue of Nature Materials Describes the Function of an Innovative Tiny Component Developed by Researchers of KIT's Institute of Nanotechnology Together with a Team of European Scientists Magnetic storage media such as hard drives have revolutionized the handling of information: We are used to dealing with huge quantities of magnetically stored data while relying on highly sensitive electronic components. And hope to further increase data capacities through ever smaller components....

Tiny fibres used to strengthen items such as bike frames and hockey sticks could pose risks to workers who make them. Certain types of carbon nanotubes - cylindrical molecules about one-thousandth of the width of a human hair - could cause cancer in the lining of the lung, University research shows. The study in mice found short carbon nanotubes appear relatively harmless if they entered lung cavities. However, longer nanotubes were more likely to get stuck there and ultimately cause a type...

In this month's Physics World, Jason Reese, Weir Professor of Thermodynamics and Fluid Mechanics at the University of Strathclyde, describes the role that carbon nanotubes (CNTs) could play in the desalination of water, providing a possible solution to the problem of the world's ever-growing population demanding more and more fresh drinking water. Global population projections suggest that worldwide demand for water will increase by a third before 2030. But with more than a billion people...

Engineering structures on the smallest possible scales "” using molecules and individual atoms as building blocks "” is both physically and conceptually challenging. An interdisciplinary team of researchers at the University of Pennsylvania has now developed a method of computationally selecting the best of these blocks, drawing inspiration from the similar behavior of proteins in making biological structures. The team was led by postdoctoral fellow Gevorg Grigoryan and professor...

Developing drugs to combat or cure human disease often involves a phase of testing with mice, so being able to peer clearly into a living mouse's innards has real value. But with the fluorescent dyes currently used to image the interior of laboratory mice, the view becomes so murky several millimeters under the skin that researchers might have more success divining the future from the rodent's entrails than they do extracting usable data. Now Stanford researchers have developed an improved...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
