Study on Shrinkage Cracking Morphology of Cement Mortar with Different Nanoclay Particles under Restraint

open access: yesBuildings, 2022
In this paper, different types and particle sizes of nanoclay (nano-metakaolin—NMK—and nano-attapulgite—NMA—clay) were selected to study the effect of nanoclay on the properties of cement-based cementitious materials.

Dispersion Interactions between Optically Anisotropic Cylinders at all Separations: Retardation Effects for Insulating and Semiconducting Single Wall Carbon Nanotubes

open access: yes, 2009
We derive the complete form of the van der Waals dispersion interaction between two infinitely long anisotropic semiconducting/insulating thin cylinders at all separations.

Compressed intramolecular dispersion interactions. [PDF]

open access: yes, 2020
The feasibility of the compression of localized virtual orbitals is explored in the context of intramolecular long-range dispersion interactions. Singular value decomposition (SVD) of coupled cluster doubles amplitudes associated with the dispersion ...

Effect of MDI Actuation Timing on Inhalation Dosimetry in a Human Respiratory Tract Model

open access: yesPharmaceuticals, 2022
Accurate knowledge of the delivery of locally acting drug products, such as metered-dose inhaler (MDI) formulations, to large and small airways is essential to develop reliable in vitro/in vivo correlations (IVIVCs). However, challenges exist in modeling

Analysis of terahertz generation using tilted-pulse-fronts

open access: yes, 2018
A 2-D spatio-temporal analysis of terahertz generation by optical rectification of tilted-pulse-fronts is presented. Closed form expressions of terahertz transients and spectra in two spatial dimensions are furnished in the undepleted limit. Importantly,

Dispersive Methods

open access: yes, 2014
This chapter discusses dispersive means of obtaining spectral resolution in spectrophotometry. These methods are used to spatially disperse or separate the various wavelengths of optical electromagnetic radiation to enable analysis of material properties in wavelength bandwidths that are appropriate to the material, the material property, and the ...

Evidence for an energy scale for quasiparticle dispersion in Bi_2Sr_2CaCu_2O_8

open access: yes, 2000
Quasiparticle dispersion in $Bi_{2}Sr_{2}CaCu_{2}O_{8}$ is investigated with improved angular resolution as a function of temperature and doping. Unlike the linear dispersion predicted by the band calculation, the data show a sharp break in dispersion at

Rayleigh-Wave Dispersion Analysis and Inversion Based on the Rotation

open access: yesSensors, 2022
Rotational observation is essential for a comprehensive description of the ground motion, and can provide additional wave-field information. With respect to the three typical layered models in shallow engineering geology, under the assumption of linear ...
