Tuning Stability and Optoelectronic Properties of CsSnI3 Via Rare‐Earth Doping

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Sn‐based halide perovskites are promising optoelectronic materials but are limited by poor stability. Thus, rare‐earth elements (RE) doping in CsSnI3 addresses this limitation, significantly enhancing thermodynamic, mechanical, and chemical stability, while simultaneously tuning electronic characteristics and modulating optical responses in the ...

Dependencies of Shear Wave Velocity and Shear Modulus of Soil on Saturation

Journal of Engineering Mechanics - ASCE, 2016
AbstractShear wave propagation in soil is a physical phenomenon and has been used widely for monitoring and seismic property assessment in geotechnical engineering. Shear wave velocity Vs and small-strain shear modulus G0 are the key parameters in defining material response to various dynamic loadings.

Velocities of compressional and shear waves in limestones

Geophysical Prospecting, 2003
Carbonate rocks are important hydrocarbon reservoir rocks with complex textures and petrophysical properties (porosity and permeability) mainly resulting from various diagenetic processes (compaction, dissolution, precipitation, cementation, etc.). These complexities make prediction of reservoir characteristics (e.g.

Shear‐wave velocity estimation

SEG Technical Program Expanded Abstracts 1993, 1993
Shear-wave velocity estimation from principally porosity, clay content and compressional velocity has been widely studied by different authors for different core samples. When comparing the results of the velocity estimated with those laws and the velocity measured on core or with sonic logs and seismic data, discrepancies are often seen.

A further comparison of shear-wave velocities

Canadian Geotechnical Journal, 1982
In a previous paper by the same authors the values of the shear-wave velocity in natural soils found from laboratory tests were compared with wave velocities measured in situ. Dynamic free-vibration torsion tests were carried out in the laboratory on undisturbed 150 × 75 mm soil samples. Downhole seismic tests were performed at the site to measure the
