Moving dislocations experience a damping force because of their interactions with lattice phonons and electrons. Except at velocities close to the transverse sound velocity this force is proportional to the dislocation velocity. At high plastic strain rates dislocations may be required to move so ...
Dye tracing has been used to study plant structure for almost a century [26], and functions by staining certain anatomical structures, and the distribution of dyes can be observed either macroscopically or under the microscope. Microscopy techniques are also well established and can be used to ...
A total of 7,810 micrograph stacks were recorded on an FEI Titan Krios electron microscope (Thermo Fisher) operated at 300 kV equipped with a K3 direct electron detector (Gatan) operated in the counting mode. Micrograph stacks were collected at a nominal magnification of ×81,000 using a ...

Antibodies represent one of the most useful probes for the study of plant cell walls, on the biochemical as well as on the structural levels in light and electron microscopy [19]. Tremendous progress has been made in the precise determination of cellular and subcellular distribution of cell wall...
TEM analysis was performed by observing the ultra-thin section on the grids under the 80 kV Hitachi H-7650 transmission electron microscope (Hitachi High-Technologies Corporation, Japan) with a charge-coupled device (CCD) camera. 3D electron tomography The electron tomography observation procedures ...
with a stronger three-dimensionality under the microscope compared to solid nanoparticles. Potential, particle size distribution could be assessed using dynamic light scattering, nanoflow cytometry and nanoparticle tracking analysis. The potential of PDNVs is negative and the size usually ranges from 18 ...
The total number of individuals infecting each plant is scored by manual assessment under the microscope. While extremely powerful, the assay has some clear limitations: (i) it requires access to microscopy equipment; (ii) due to the manual effort involved only a small number of genotypes can ...
Electron microscopy revealed Aβ-immunopositive signals on the surfaces of the EVs isolated from plant ceramide-treated cell cultures that had been incubated with soluble synthetic Aβ40 at room temperature for 10 min (Fig. 2c). The binding of Aβ to neuron-derived EVs leads to Aβ ...
A field emission scanning electron microscope (Verios FE1) was used to characterize the morphology of various samples, which were made conductive by coating with a 10 nm layer of gold before characterization, while the acceleration voltage was kept at 2.0 kV. Typically three cross-sections of ...
