Size dependence at the nanoscale By size effect we mean a dependence of a material parameter such as Young's modulus on a specimen size which is used for the parameter determination. In mechanics of...Eremeyev, Victor A.Gdańsk University of Technology...
The size effect in the bending of a Timoshenko nanobeam is investigated in this paper based on a recently developed elastic theory for nanomaterials in which only the bulk surface energy density and the surface relaxation parameter are involved as independent parameters to characterize the surface ...
Furthermore, we explored the distribution efficiency and processing of LNT-UsSeNPsin vivo.After the injection of fluorescently labeled Se nanoparticles, the fluorescence intensity at the SCI site in the LNT-UsSeNPs group was significantly higher at various time points than in the LNT-SeNPs group, ...
In subject area: Chemistry Quantum size effect refers to the phenomenon that when particle size drops to a certain value, the electron energy level near Fermi level changes from quasi-continuous energy level to discrete energy level, that is, energy level splitting or energy gap widening. ...
[41] has been used to determine the effect of size, induced by plastic strain gradient, on the formation of plastic shocks in porous materials. In particular, we have shown that the critical cavity expansion velocity for which plastic shocks emerge increases with the length scale parameter that...
(CuZn10) where the diameter of the cylinder is scaled down from 5 mm to 1 mm, in order to evaluate the size effects on the flow stress. Compression tests were carried out by reducing the height of the cylinder by 80% at a constant rate of 0.03 mm/s and without lubricant. During ...
Nanoconfinement effect is crucial to improve the dehydrogenation kinetics of MgH2. However, the underlying micro-mechanism for nanoconfinement effect of carbon-based carrier on MgH2 nanoparticles is still ambiguous, hindering the design of carbon-based nanoconfined MgH2 nanoparticles. To address this dile...
Asymmetric Janus transition metal dichalcogenide MoSSe is a promising catalytic material due to the intrinsic in-plane dipole of its opposite faces. The atomic description of the structures observed by experimental techniques is relevant to tuning and optimizing its surface reaction processes. Furthermore...
In addition, since our focus is the effect of particle size and Zp on NP diffusion, the factors that cannot be mathematically described could be treated as a lumped system [38], which means that although every one of the factors inside the lumped system may manipulate the movement of the ...
nanomaterials, and that the methodology developed for our kinetic study will be helpful to investigate and exploit solid–solid transformations in other semiconductor nanocrystals. The findings on structural isomerism should stimulate attention toward advanced design and synthesis of functional nanomaterials ...
