Read moreFriction Differences Offer New Tool in Carbon Nanotubes
Publishing in the journal Nature Materials this week, researchers from four different institutions report measuring different friction forces when a carbon nanotube slides along its axis compared to w...
Materials Sciences | Read more'Factory Worker' Signals in Cells Hold Possible Key to Anti-cancer Drugs
Like any appliance, proteins in living cells eventually become obsolete. The body relies on intricate machinery to tag proteins for recycling at a molecular factory, where they are chopped into pieces...
Life Sciences | Read moreDiscovery to aid study of biological structures, molecules
The researchers demonstrated their new understanding of how the instrument - the atomic force microscope - works in water to show detailed properties of a bacterial membrane and a virus called Phi29, ...
Life Sciences | Read moreSingle-molecule technique captures calcium sensor calmodulin in action
It's well known that the protein calmodulin specifically targets and steers the activities of hundreds of other proteins – mostly kinases – in our cells, thus playing a role in physiologically im...
Life Sciences | Read morePlastics That Convert Light to Electricity Could Have a Big Impact
Researchers the world over are striving to develop organic solar cells that can be produced easily and inexpensively as thin films that could be widely used to generate electricity.But a major...
Power and Electrical Engineering | Read moreOn quantum paths through the helium atom
This forms an essential basis for electron holography of atoms (Physical Review Letters 103, 053001).How do electrons move inside an atom and what happens in detail if this motion is distorted...
Physics and Astronomy | Read moreUCR scientists manipulate ripples in graphene, enabling strain-based graphene electronics
Graphene is nature's thinnest elastic material and displays exceptional mechanical and electronic properties. Its one-atom thickness, planar geometry, high current-carrying capacity and thermal c...
Power and Electrical Engineering | Read moreNIST Develops Novel Ion Trap for Sensing Force and Light
Miniature devices for trapping ions (electrically charged atoms) are common components in atomic clocks and quantum computing research. Now, a novel ion trap geometry demonstrated at the Natio...
Physics and Astronomy | Read moreNew statistical technique improves precision of nanotechnology data
A new statistical analysis technique that identifies and removes systematic bias, noise and equipment-based artifacts from experimental data could lead to more precise and reliable measurement of nano...
Studies and Analyses | Read moreStreaming sand grains help define essence of a liquid
Physicists seeking to answer this question have, for the first time, measured the nanoscale forces that cause droplet formation in a falling stream of tiny glass beads. John Royer, a graduate student ...
Physics and Astronomy | Read moreFindings uncover new details about mysterious mimivirus
The mimivirus has been called a possible "missing link" between viruses and living cells. It was discovered accidentally by French scientists in 1992 but wasn't confirmed to be a virus ...
Life Sciences | Read moreHome tooth bleaching slightly reduces enamel strength
The researchers noted that teeth typically can restore their previous hardness after losing small amounts of enamel calcification. But this is the first study to show at a nanometer scale – measuring ...
Health and Medicine | Read moreResearchers find better way to manufacture fast computer chips
Experts believe that graphene -- the sheet-like form of carbon found in graphite pencils -- holds the key to smaller, faster electronics. It might also deliver quantum mechanical effects that could en...
Materials Sciences | Read moreNew Molecular Force Probe Stretches Molecules, Atom by Atom
The researchers use stiff stilbene, a small, inert structure, as a molecular force probe to generate well-defined forces on various molecules, atom by atom.“By pulling on different pairs of at...
