Effect of Wet–Dry Cycling on Properties of Natural-Cellulose-Fiber-Reinforced Geopolymers: A Short Review

open access: yesMolecules, 2023
To study the long-term properties of cement-based and geopolymer materials exposed to outdoor environments, wet–dry cycles are usually used to accelerate their aging.

On the Sharpness and Bias of Quantum Effects [PDF]

open access: yes, 2009
The question of quantifying the sharpness (or unsharpness) of a quantum mechanical effect is investigated. Apart from sharpness, another property, bias, is found to be relevant for the joint measurability or coexistence of two effects.

Mechanical testing of two-dimensional materials: a brief review

open access: yesInternational Journal of Smart and Nano Materials, 2020
Two-dimensional (2D) materials have dominated nanoscience for the last two decades. Among all 2D materials, graphene, MoS2, and h-BN are extremely popular and have been tentatively scaled up to fabricate nanocomposites, energy storage devices, flexible ...

A comparative study of rafting mechanisms of Ni-based single crystal superalloys

open access: yesMaterials & Design, 2020
It is known that Ni-based superalloys experience microstructural rafting during high temperature straining. This paper presents a comparative study of the different rafting models by means of finite element modeling and experimentation investigation.

Mechanical Properties of Axons

open access: yesPhysical Review Letters, 2007
The mechanical response of PC12 neurites under tension is investigated using a microneedle technique. Elastic response, viscoelastic relaxation, and active contraction are observed. The mechanical model proposed by Dennerll et al. [J. Cell Biol. 109, 3073 (1989).10.1083/jcb.109.6.3073], which involves three mechanical devices--a stiff spring kappa ...
