Relating pore fabric geometry to acoustic and permeability anisotropy in Crab Orchard Sandstone: A laboratory study using magnetic ferrofluid [PDF]

open access: yes, 2003
Pore fabric anisotropy is a common feature of many sedimentary rocks. In this paper we report results from a comparative study on the anisotropy of a porous sandstone (Crab Orchard) using anisotropy of magnetic susceptibility (AMS), acoustic wave ...

Thermal Oxidation Preparation of Doped Hematite Thin Films for Photoelectrochemical Water Splitting

open access: yesInternational Journal of Photoenergy, 2014
Sn- or Ge-doped hematite thin films were fabricated by annealing alloyed films for the purpose of photoelectrochemical (PEC) water splitting. The alloyed films were deposited on FTO glass by magnetron sputtering and their compositions were controlled by ...

Charge-Transfer Process in Surface-Enhanced Raman Scattering Based on Energy Level Locations of Rare-Earth Nd3+-Doped TiO2 Nanoparticles

open access: yesNanomaterials, 2021
Surface-enhanced Raman scattering (SERS) for semiconductor nanomaterial systems is limited due to weak Raman signal intensity and unclear charge-transfer (CT) processes for chemical enhancement.

Development of novel lightweight and cost-effective Mg–Ce–Al wrought alloy with high strength

open access: yesMaterials Research Letters, 2021
The low microalloying content and high yield strength of 365 MPa have been achieved simultaneously in extruded Mg–Ce–Al alloy which is mainly ascribed to the unexpected grain refinement (mean size of ∼420 nm).

Anisotropy-based mechanism for zigzag striped patterns in magnetic thin films [PDF]

open access: yes, 2014
In this work we studied a two dimensional ferromagnetic system using Monte Carlo simulations. Our model includes exchange and dipolar interactions, a cubic anisotropy term, and uniaxial out-of-plane and in-plane ones.

Joint anisotropy and source count constraints on the contribution of blazars to the diffuse gamma-ray background [PDF]

open access: yes, 2012
We place new constraints on the contribution of blazars to the large-scale isotropic gamma-ray background (IGRB) by jointly analyzing the measured source count distribution (logN-logS) of blazars and the measured intensity and anisotropy of the IGRB.

Hot Corrosion Behavior of a Novel Co-base Superalloy in Molten NaCl at 900℃

open access: yesCailiao gongcheng, 2018
Hot corrosion behavior of a new cobalt-base superalloy at 900℃ in the molten NaCl was investigated by salt-leaching method. The results show that the selective oxidation occurs at the initial stage of corrosion, and the oxidation films including Al2O3 ...
