Atomic force microscopy images show that nanowires are formed for deposition in the temperature range of 400480 degrees C, a [J. Appl. Phys. 100, 114305 (2006)] published Tue Dec 5, 2006
Exploring the nanoworld with atomic force microscopy
Over its 20-year history, the atomic force microscope has gradually evolved into an instrument whose spatial resolution is now fine enough to image subatomic features on the scale of picometers
Atomic Force Microscopy Of Soft Or Fragile Materia
TappingMode imaging is a key advance in atomic force microscopy (AFM) of soft, adhesive or fragile samples. This patented technique allows high resolution topographic imaging of sample surfaces that are easily damaged, loosely held to
Taste - What is it?
Samples from my last immersion: physicists at the University of Nottingham, England, probe the surface of caramel with an atomic-force microscope to understand the molecular nature of its stickiness. A laser-scanning microscope at the
Breaking bonds in the atomic force microscope: Theory and analysis
A theoretical framework is developed to analyze molecular bond breaking in dynamic force spectroscopy using atomic force microscopy. An analytic expression of the observed bond breaking probability as a function of force is obtained in

Mapping the wave pattern of light with an Atomic Force Microscope
Using the tip of an Atomic Force Microscope (AFM), it is possible to map the wave pattern of light, trapped in a so called optical resonator, with unprecedented precision. Apart from that, the AFM is also capable of playing with the
Atomic force microscope tests explosives
Researchers at Georgia Institute of Technology and Texas Tech University, both in the US, have used an atomic force microscope (AFM) to analyse the nanoscale thermal properties of pentaerythritol tetranitrate (PETN), an explosive
Systematic variations in apparent topographic height as measured
The contact potential difference between the tip and the two well-defined regions of similar material is utilized to examine the effects and interplay of essential tip-sample forces in atomic force microscopy. Measurements
Noncontact atomic force microscopy imaging of water dissociation
We have imaged the products of water dissociation on TiO_{2}(110) with noncontact atomic force microscopy (NC-AFM). Scanning tunneling microscopy (STM) experiments have revealed that water splits into a hydroxyl group that sits in an O

How To Herd Atoms: Researchers Observe Self-organization Of Atoms In Circular Atomic Pens Science Daily
Max Planck researchers in Halle observe self-organization of atoms in circular atomic pens.
How to herd atoms PhysOrg
It has long been known that it is possible to confine electrons or atoms in atomic structures in the same way as sheep can be shut in a pen. Physicists at the Max Planck Institute for Microstructure Physics in Halle have now discovered a strange thing: if the atomic fences have the right shape and the substrate, temperature and other parameters are adjusted appropriately, then randomly
Strontium Atomic Clock Demonstrates Super-fine 'Ticks' Science Daily
Using an ultra-stable laser to manipulate strontium atoms trapped in a "lattice" made of light, scientists at JILA (a joint institute of NIST and the University of Colorado at Boulder) have demonstrated the capability to produce the most precise "ticks" ever recorded in an optical atomic clock--techniques that may be useful in time keeping, precision measurements of high frequencies, and quantum
Magnetic Needles Turn Somersaults: Researchers Discover New Possibilities For Magnetic Storage Science Daily
Scientists at the Max Planck Institute of Metals Research in Stuttgart have discovered a new mechanism with which it is possible to use weak magnetic fields to reverse tiny magnetic structures, called vortex cores, quickly and with no losses. Up until now, very strong magnetic fields have been necessary to accomplish this, requiring highly complex technology. The new method might open up new
Yvonne Yamanaka '08 Duke University
Yvonne Yamanaka made an early discovery at Duke – faculty members are quite accessible. “A few weeks after beginning my freshman year at Duke I e-mailed a professor in the chemistry department to ask if I could get involved in the research that his lab was doing,” she says.

Nearly Unbreakable: Novel Nanoscale Construction Principle Prevents Bones From Breaking At Science Daily
Max Planck Scientists discover a novel construction principle at the nanoscale which prevents bones from breaking at excessive force.
Ultra-intense Laser Blast Creates True 'Black Metal' Science Daily
"Black gold" is not just an expression anymore. Scientists at the University of Rochester have created a way to change the properties of almost any metal to render it, literally, black. The process, using an incredibly intense burst of laser light, holds the promise of making everything from fuel cells to a space telescope's detectors more efficient -- not to mention turning your car into the
On The Cutting Edge: Carbon Nanotube Cutlery Science Daily
Researchers at NIST and the University of Colorado at Boulder have designed a prototype carbon nanotube "knife" that would work like a tight-wire cheese slicer for cutting cells, allowing scientists to study them more precisely than they can today.
