Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes

open access: yesAdvanced Functional Materials, EarlyView.
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

INVESTIGATION OF FAULTING PROCESSES OF TWO M5 EARTHQUAKE SEQUENCES IN OKLAHOMA [PDF]

open access: yes, 2017
I investigate the stress interaction inside different earthquake clusters to better understand the factors that might drive and control seismicity. I examine a catalog of 6226 events that have been relocated using the GrowClust method.

Anisotropic Phonon Dynamics and Directional Transport in Actinide Van der Waals Semiconductor Uranium Triselenide

open access: yesAdvanced Functional Materials, EarlyView.
USe3 is introduced as an actinide van der Waals semiconductor that mirrors the quasi‐one‐dimensional physics of transition‐metal trichalcogenides. Polarization‐resolved Raman spectroscopy on exfoliated flakes maps strong in‐plane phonon anisotropy and strain‐tunable mode shifts.

Stress-dilatancy Relation for Mohr-Coulomb Soils Following a Non-Associated Flow Rule [PDF]

open access: yes, 2010
Rowe\u27s stress–dilatancy relation for frictional (cohesionless) materials has been a cornerstone of soil mechanics. The original derivation of this relationship was based on incorrect energy minimisation considerations, but the relationship was proven ...

Coseismic Coulomb stress changes induced by a 2020–2021 MW > 7.0 Alaska earthquake sequence in and around the Shumagin gap and its influence on the Alaska-Aleutian subduction interface

open access: yesGeodesy and Geodynamics
Three MW > 7.0 earthquakes in 2020–2021 occurred in the Shumagin seismic gap and its adjacent area of the Alaska-Aleutian subduction zone, including the MW7.8 Simeonof thrust earthquake on July 22, 2020, the MW7.6 Sand Point strike-slip earthquake on ...

Coulomb stress change on inland faults during megathrust earthquake cycle in southwest Japan

open access: yesEarth, Planets and Space, 2020
In the subduction zone, megathrust earthquakes may modulate the shallow crustal seismicity in the overriding plate. Historical documents indicate the frequent occurrence of large shallow crustal earthquakes in the overriding continental plate 50 years ...

Study of Coulomb Stress Change (CSC) Earthquake in the Segment Area of West Seram – Ambon Island

open access: yesJurnal Penelitian Pendidikan IPA, 2022
Long beans are short-lived plants that are widely cultivated in Indonesia. To stimulate the growth of long beans, it is necessary to fertilize with the appropriate dose for its growth. Research on the effect of vermicompost and NPK fertilizer has been carried out in Mertak Umbak Village, Central Lombok.

Covalent Functionalization of 2D Semiconductors: A Roadmap to Advanced Electronic Devices

open access: yesAdvanced Functional Materials, EarlyView.
This Review presents recent advances in the covalent functionalization strategies for two‐dimensional semiconductors and their implementation in modern technologies. Layered materials are modified through diverse molecular chemistries (e.g., thiols, diazonium salts, alkyl halides, and electron‐deficient species) to tailor their surface properties ...

Coulomb excitation and break up [PDF]

open access: yes, 1988
Break up processes involving a three body system in the Coulomb field are studied. A method is developed for the realistic treatment of such a system, and is applied to the break up of the nucleus, 7Li.

Slip Models of the 2016 and 2022 Menyuan, China, Earthquakes, Illustrating Regional Tectonic Structures

open access: yesRemote Sensing, 2022
As one of the large-scale block-bounding faults in the northeastern Tibetan Plateau, the Qilian-Haiyuan fault system accommodates a large portion of north-eastward motion of the Tibetan Plateau. In 2016 and 2022, two strong earthquakes of Mw6.0 and Mw6.6
