Pressure Transmission Efficiency and Changing Pattern of Hydrostatic Pressure of Cement Slurries

open access: yesZuanjingye yu wanjingye
The decline of the hydrostatic pressure of a cement slurry is considered to be one of the main causes resulting in early annular gas channeling, and annular gas channeling in turn is a key factor hindering normal oil and gas production.

Effect of moderate hydrostatic pressure on crystallization of palm kernel stearin-sunflower oil model systems

open access: yesCurrent Research in Food Science
Lipid crystallization under moderate hydrostatic pressure treatments (200 MPa, 20 °C, 1–24 h) was studied in palm kernel stearin (PS 100%) and its blends with sunflower oil (PS 80, 90 % w/w).

Effect of high hydrostatic pressure on seed germination, microbial quality, anatomy-morphology and physiological characteristics of garden cress (Lepidium sativum) seedlings

open access: yes, 2013
High hydrostatic pressure is a non-thermal food processing technology that is found to increase the percentage of germination, decrease the germination time and improve the microbial quality of seeds. In this study, pressures of 100-400 MPa for 10 min at

Real‐time monitoring of root dielectric properties for assessing crop plant damage caused by foliar application of glyphosate

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise There is a knowledge gap regarding how foliar injury and restricted water uptake can be detected by measuring root dielectric response. This pot study nondestructively evaluated the efficiency of real‐time dielectric measurement to monitor the effects of glyphosate spraying.

Structural Analysis of Oil-Spill Boom Grounding at Low Tide

open access: yesJournal of Marine Science and Engineering
Oil-spill booms in shallow waters and high tidal amplitudes could ground on the seabed and retain high amounts of seawater. The object of this study is to estimate the mooring force at both boom section ends and the occurrence of submarining observed ...

On the Impact of Mechanical Constraint on Band Structure and Photo‐Elastic Effect in Photonic Resonators

open access: yesAdvanced Physics Research, EarlyView.
We computationally investigate the mechanical, electronic, and optical properties of strained GeSn microdisks on silicon substrates. By combining photo‐elasticity, strain‐dependent band‐structure calculations, and optical mode analysis, we study how strain distribution, structural configuration, and temperature affect the electronic band structure and ...

Pressure-induced phase transitions of KTiOAsO4 by Raman spectroscopy

open access: yes, 1998
Potassium titanyl orthoarsenate KTiOAsO4 has been studied by Raman spectroscopy up to 16 GPa. Three first-order pressure-induced phase transitions are inferred from Raman data. The first phase transition takes place at 3.

Raman Response of Monolayer Graphene Upon Varying TCNE Adsorption

open access: yesAdvanced Physics Research, EarlyView.
Low TCNE loading induces p‐type doping in monolayer graphene without significantly disturbing local lattice symmetry, due to a structurally favorable molecular arrangement. At higher TCNE concentrations, the D‐band emergence indicates increasing symmetry breaking. TCNE thus enables concentration‐dependent tuning of graphene's electronic properties with

High pressure study of the 2D polymeric phase of C60 by means of Raman spectroscopy

open access: yes, 2000
The effect of high hydrostatic pressure, up to 12GPa, on the intramolecular phonon frequencies and the material stability of the two-dimensional tetragonal Cm polymer has been studied by means of Raman spectroscopy in the spectral range of the radial ...
