Material structure, properties, and dynamics through scanning transmission electron microscopy

open access: yesJournal of Analytical Science and Technology, 2018
Scanning transmission electron microscopy (STEM) has advanced rapidly in the last decade thanks to the ability to correct the major aberrations of the probe-forming lens. Now, atomic-sized beams are routine, even at accelerating voltages as low as 40 kV,

Use of electron microscopy to study platelets and thrombi

open access: yesPlatelets, 2020
Electron microscopy has been a valuable tool for the study of platelet biology and thrombosis for more than 70 years. Early studies using conventional transmission and scanning electron microscopy (EM) provided a foundation for our initial understanding ...

Biomass derived mesoporous carbon monoliths via an evaporation-induced self-assembly [PDF]

open access: yes, 2013
Evaporation-induced self-assembly has been applied in the synthesis of crack-free mesoporous carbon monolith with good mechanical stability using a waste plant material as carbon precursor and triblock copolymer F127 as template.

A combined FEG-SEM and TEM study of silicon nanodot assembly [PDF]

open access: yes, 2008
Nanodots forming dense assembly on a substrate are difficult to characterize in terms of size, density, morphology and cristallinity. The present study shows how valuable information can be obtained by a combination of electron microscopy techniques.

Structural and gas-sensing properties of CuO–CuxFe3−xO4 nanostructured thin films [PDF]

open access: yes, 2010
Nanocrystalline CuO–CuxFe3−xO4 thin films were developed using a radio-frequency sputtering method followed by a thermal oxidation process. Thin films were deposited applying two very different conditions by varying the argon pressure and the target-to ...

The effect of carbon coating on the electrochemical performance of nanosized Li2FeSiO4 cathode materials [PDF]

open access: yes, 2013
Carbon-coated Li2FeSiO4/C cathode materials have been synthesized through a modified ball-milling pro- cess. The physical characterizations of Li2FeSiO4 were conducted by using X-ray powder diffraction, field-emission scanning electron microscopy and ...

Cathodoluminescence of silicon doped aluminum nitride with scanning transmission electron microscopy

open access: yesAPL Materials, 2020
Here, we apply cathodoluminescence in scanning transmission electron microscopy to infer the influence of dislocation strain fields on the formation of point defect complexes in Si doped AlN. In addition to identifying non-radiative recombination centers,

Biological Scanning Transmission Electron Microscopy: Imaging and Single Molecule Mass Determination

open access: yesCHIMIA, 2006
Scanning transmission electron microscopes can both measure the mass of single protein complexes and take amazingly clear images thereof, offering a wide range of applications in structural biology. The principle of mass measurement is presented

Synthesis and characterization of spherical amorphous alumo-silicate nanoparticles using RF thermal plasma method [PDF]

open access: yes, 2013
The RF thermal plasma synthesis route was used for the preparation of alumo-silicate spherical particles. Homogeneous solid mixtures of raw materials (Al2O3, SiO2 and KOH) were used as precursors.
