Doing it yourself may not get you the most precise lab equipment in the world, but it gets you a hands-on appreciation of the techniques that just can’t be beat. Today’s example of this adage: [Stoppi ...

Anyone who has ever taken the time to critically examine a walnut knows that a two-dimensional photograph fails in many respects to truly convey the unique features--the nicks, crannies, valleys, and ...

Today we're looking at Atomic Force Microscopy! I built a "macro-AFM" to demonstrate the principles of an atomic force microscope, then we look at a real AFM (an nGauge AFM from ICSPI) and do a few ...

An atomic force microscope (AFM) taps on samples with a tiny probe, instead of using light like a regular microscope. They can generate 3D images with nanometer precision. The AFM in this video is an ...

A further development in atomic force microscopy now makes it possible to simultaneously image the height profile of nanometer-fine structures as well as the electric current and the frictional force ...

Electron spin resonance (ESR) is a key tool for the spectroscopic characterization of chemicals. It relies on resonantly changing the spin state of electrons (spin is an intrinsic quantum property of ...

Invented 30 years ago, the atomic force microscope has been a major driver of nanotechnology, ranging from atomic-scale imaging to its latest applications in manipulating individual molecules, ...

Scientists at the Department of Energy's Oak Ridge National Laboratory have reimagined the capabilities of atomic force microscopy, or AFM, transforming it from a tool for imaging nanoscale features ...
