Single-crystal Cu nanorods have been fabricated on carbon films by manipulating electron beam irradiation on a Cu powder charge in a transmission electron microscope (TEM). By adjusting the intensity of the electron beam, we observed lively nucleation and growth of the Cu nanorods with the TEM. Individual Cu nanorods are straight with diameters ranging from 40 to 50 nm. The length of the rods i...

This article traces the important milestones in the development of high-resolution, field-emission, scanning electron microscopes (SEM). Such instruments are now capable of producing images of the surfaces of biological specimens that rival, in terms of resolution and contrast, those produced by conventional transmission electron microscopy (TEM). Even though one of the first instruments to pro...

The precession electron diffraction (PED) technique [1] has been originally developed for structure determination at a submicrometer scale in a transmission electron microscope (TEM). Since, many structures have been solved using PED, recently combined with the tomographic acquisition of 3D electron diffraction data [2]. Using PED, integrated intensities of the diffracted beams as a function of...

Low dose imaging procedures are key for a successful cryoEM experiment (whether by electron cryotomography, single particle analysis, electron crystallography, or MicroED). We present a method to minimize magnetic hysteresis of the condenser lens system in the JEOL JEM3200FSC transmission electron microscope (TEM) in order to maintain a stable optical axis for the beam path of low-dose imaging....

The discovery of energy loss magnetic chiral dichroism (EMCD) has created a new approach to element specific magnetic measurements with highest spatial resolution [1]. EMCD, which is detected in the fine structure of energy loss spectra in a transmission electron microscope (TEM) probes the same electronic transitions as its well established X-ray counterpart, the X-ray magnetic circular dichro...

Diamond-like carbon nanocomposite films with embedded silver nanoparticles are considered experimentally (spectroellipsometric characterization) and theoretically (modeling of optical properties). Metallic nanocomposite films were synthesized by reactive magnetron sputtering and were studied by transmission electron microscope (TEM) and atomic force microscope (AFM). The optical constants of th...

The transmission electron microscope (TEM) has evolved into a highly sophisticated instrument that is ideally suited to the characterization of advanced materials. Atomic-level information is routinely accessible using both fixed-beam and scanning TEMs. This report briefly considers developments in the field of atomic-resolution electron microscopy. Recent activities include renewed attention t...

Nanotechnology has a great influence on modern technology, just like the development of DNA profiling on biotechnology in the past 50 years. Because of applying knowledge and techniques from natural science, forensic science aims to identify, individualize and evaluate evidence. Evidence will then be used to reconstruct crime scenes, guide investigations and bring criminals to justice. Nanotech...

The short-range order of individual fractal-like amorphous carbon nanotips was investigated by means of energy-filtered electron diffraction in a transmission electron microscope (TEM). The nanostructures were grown in porous silicon substrates in situ within the TEM by the electron beam-induced deposition method. The structure factor S(k) and the reduced radial distribution function G(r) were ...

Dislocation slip is investigated in a metastable  titanium alloy with the Ti-23Nb-0.7Ta-2Zr0.4Si composition (at. %) by in situ straining experiments in a transmission electron microscope (TEM). Moving dislocations have a/2<111> Burgers vectors and glide in {110}, {112} or {123} planes. The mobility of screw dislocations is lowered by punctual defects and the existence of a stable and sessile ...
