Scientists Visualize Electromagnetic Fields of Nanostructures in 3D for the First Time

Whether for microscopy, data storage or sensor technology, many advanced technological applications that require specific functions rely on the structure of the electromagnetic field near the surfaces of materials. In nanosystems, so-called surface phonons, i.e. temporal distortions of the atomic lattice, contribute decisively to the physical and thermodynamic properties.

New High Speed Atomic Force Microscopy for Visualizing Biological Processes

High-speed atomic force microscopy (HS-AFM) is defined as an imaging method that can be employed for imaging biological processes, for instance, the activity of proteins. Current standard HS-AFM frame rates are as high as 12 frames per second (fps).

Study Shows How Nanocrystals Self-Organize into Stable State

Generally, when crystals are grown, atoms will initially combine together into tiny clusters. This process is referred to as nucleation.

Microscopy Technique Enables Ultrafast Electron Manipulation and Tracking of Quantum Dynamics

Since the early 2010s, ultrafast probing of materials at atomic-level resolution has been enabled by terahertz scanning tunneling microscopes (THz-STM). But these devices can't detect the dissipation of energy that happens during events such as when photons are emitted via recombination process of an electron-hole pair in a light emitting diode (LED). However, a new technique allows the tracking of just such energy dynamics alongside THz-STM, opening up new avenues of investigation for nanoscale science and technology.

Researchers Build Smallest Ever, Cheapest High Resolution Microscope

The University of Barcelona led an international team of researchers to develop the most inexpensive, smallest high-resolution microscope so far, achieved by creating new nanoLEDs that serve as a light source and identify the microscope’s resolution without the need for lenses.

New Microscopy Method Shows How Electron Interactions Stabilize Skyrmions

Physicists from RIKEN have found how interactions between electrons have the ability to stabilize a repeating arrangement of swirling magnetic patterns called skyrmions, which could enable these structures to be leveraged further.

Multipurpose X-Ray Instrument Measures Nanoscale Chemical Changes in Real Time

COSMIC, a multipurpose X-ray instrument at Lawrence Berkeley National Laboratory's (Berkeley Lab's) Advanced Light Source (ALS), has made headway in the scientific community since its launch less than 2 years ago, with groundbreaking contributions in fields ranging from batteries to biominerals.
