Influence of Arbuscular Mycorrhizal Fungi on the Growth and Development of Micropropagated Rubus fruticosus ‘P45’ Plants during Acclimatization

open access: yesHortScience, 2023
Blackberry (Rubus sp., family: Rosaceae) is an important fruit-yielding plant cultivated worldwide. Blackberry fruits are rich in nutrients and bioactive substances, such as anthocyanins and other phenolic compounds (Kaume et al. 2011). The flavonols and

Influence of cross-section geometry and wire orientation on the phonon shifts in ultra-scaled Si nanowires [PDF]

open access: yes, 2011
Engineering of the cross-section shape and size of ultra-scaled Si nanowires (SiNWs) provides an attractive way for tuning their structural properties. The acoustic and optical phonon shifts of the free-standing circular, hexagonal, square and triangular

Phase Stability and Microstructure Evolution of Solution-Hardened 316L Powder Feedstock for Thermal Spraying

open access: yesMetals, 2018
A solution-hardening of AISI 316L stainless-steel powder was conducted. The expansion of the crystal lattice and a strong increase in the nanoindentation hardness confirm the successful diffusion of carbon and nitrogen in the interstices.

Changes of Material Properties of Silumin During Age-Hardening

open access: yesCommunications, 2012
Simple phenomenological description of age-hardening kinetics of supersaturated solid solution is presented using the sum of exponential functions with negative arguments containing rate constants whose temperature dependence is described by the ...

Dynamics of Dislocations in Smectic A Liquid Crystals Doped with Nanoparticles

open access: yesCrystals, 2019
Edge dislocations are linear defects that locally break the positional order of the layers in smectic A liquid crystals. As in usual solids, these defects play a central role for explaining the plastic properties of the smectic A phase. This work focuses

Strain Hardening of Polymer Glasses: Entanglements, Energetics, and Plasticity [PDF]

open access: yes, 2008
Simulations are used to examine the microscopic origins of strain hardening in polymer glasses. While stress-strain curves for a wide range of temperature can be fit to the functional form predicted by entropic network models, many other results are ...
