Surface Resistivity (SR) of water-saturated concrete at several different ages was studied and compared to the diffusion properties of the same concrete. A case is made to use SR as an electrical indicator of concrete chloride penetration resistance because of its strong correlation to diffusion ...
Surface topography is the nature of a surface as defined by the three characteristics: Lay – The direction of the predominant surface pattern ordinarily determined by the production method used Surface roughness – Closely spaced irregularities (cutting tool marks, grit of grinding wheel). In enginee...
Electric Resistivity TomographyVertical Electrical SoundPiper DiagramGeoelectrical DataIn Romania, surface waters near underground salt mines represent a significant risk to the stability of the mine workings. Such problems occur in many salt exploiting facilities, i.e. Slanic Prahova, Targu Ocna, Praid...
random alloys and partial inclinations of the multi-layers, the band gaps of ZnMgO broadened from 3.3 to 3.7 eV, and resistivity increased to 1.58 × 108Ω·cm; the work function of AgyO films increased to 5.6 eV at the highest O2 flow rate (R[O2] = 30%) during the sputtering ...
From the utilitarian point of view, very good thermal stability, promising mechanical properties being: H ∼ 16 GPa, E∗ ∼ 180 GPa (NanoTest) and low value of resistivity below 650 μΩcm (4-point probe method) of the Mo-N, predestine them as an effective diffusion...
Underneath the water bottom is mud/shale inter-bed with a depth greater than 50 m and resistivity ranging from 1 to 5 ohm-m. The depth of the clayey layer predicted by TEM data is comparable to that of drilled wells nearby, and the thick mud to the southeast suggests the lake dipping ...
For all experiments in this study, DNase/RNase-free distilled water (Life Technologies/Thermo Fisher Scientific, USA) was used to minimize potential pollutants or ice-nucleating agents, except DSC trials of 100 ml water where deionized (DI) water (resistivityR = 18.2 MΩ) produced by...
Resistivity on the glacier surface, magnetic susceptibility of rocks, electromagnetic noise and total earth's magnetic field measurements confirm that the MRS survey took place in the best conditions. MRS data show different signals amplitudes at the Larmor frequency according to the loop dimension. ...
PROBLEM TO BE SOLVED: To reduce the radiation exposure dose of workers during periodic inspection and the like by easily improving the corrosion resistivity of nuclear fuel element without using any special device and suppressing the surface radiation dose rate of the primary cooling system pipes. SO...
Temperature dependent resistivity measurements show that both the samples are semiconducting with deep level defect states. Our findings suggest the possibility of incorporating spin functionality in non-polar optoelectronic devices. select article Yolk-shelled Ni2P@carbon nanocomposite as high-performance ano...
