Phase transition mechanism and bandgap engineering of Sb2S3 at gigapascal pressures

Communications Chemistry, 2021
Antimonite (Sb2S3) has potential applications for solar energy, but how its layered structure changes under pressure is incompletely understood. Here diamond anvil cell experiments supported by first principles calculations offer a structural explanation

Formation of an Al‐Rich Niccolite‐Type Silica in Subducted Oceanic Crust: Implications for Water Transport to the Deep Lower Mantle

Geophysical Research Letters, 2022
Subducted oceanic crust is enriched in free silica. Although being one of the silica polymorphs at lower‐mantle pressures, niccolite‐type phase (Nt‐phase) has not been documented in multicomponent metabasaltic or metasediment compositions relevant to ...

Passive Earth Pressure in Narrow Cohesive-Frictional Backfills

, 2023
A narrow backfill zone is formed when retaining walls are built near existing stabilized structures (e.g., rock faces). In such circumstances, the classical passive earth pressure coefficient is no longer applicable, and a correction factor is required ...

Earth Pressure During Earthquake

Soils and Foundations, 1973
ABSTRACT In order to estimate the active earth pressure and the earth pressure at rest against the walls during earthquake, the authors carried out the tests using a large scale vibrating soil bin in laboratory. The resultant force due to the oscillating earth pressure, its applied point and the angle of wall friction were measured during the wall ...

An investigation into the role of time-dependent cohesion in interseismic fault restrengthening

Scientific Reports, 2019
Earthquakes typically exhibit recurrence times that far exceed time-scales attainable in a laboratory setting. To traverse the temporal gap between the laboratory and nature, the slide-hold-slide test is commonly employed as a laboratory analogue for the

T1–T2 microscale correlation relaxometry for in situ high-pressure nuclear magnetic resonance [PDF]

Matter and Radiation at Extremes
Over the last decade, frequency-domain in situ high-pressure nuclear magnetic resonance (NMR) spectroscopy in diamond anvil cells (DACs) has been employed as a structural and electronic probe of condensed matter systems at pressures well into the megabar

Fibre Bragg grating based effective soil pressure sensor for geotechnical applications [PDF]

, 2009
An effective-soil-pressure sensor for geotechnical applications based on Fibre Bragg Gratings is presented. The sensor simultaneous measures total soil pressure and pore pressure, allowing the calculation of the effective stress of soil.
