Evaluation of Resistivity Meters for Concrete Quality Assurance, Project TR201414
… to verify existing relationships between surface resistivity (SR), rapid chloride permeability (RCP), chloride ion diffusion, and the AASHTO penetrability classes. The research also performed a precision and bias evaluation to provide acceptable limits should SR be implemented for quality …

Durability Assessment and Service Life Prediction of Concrete in Extreme Aggressive Environment
… between chloride diffusion rates and concrete resistivity. By identifying these correlations and based on the target service life, the research aims to set appropriate thresholds for Surface Resistivity (SR) and Bulk Resistivity (BR) tests, which will be used to qualify concrete mixes used in …

Enhancing Urban Energy Sustainability through PCM-Integrated Mortar Infrastructure
… thermal conductivity, specific heat capacity, surface resistivity, and water absorption. The optimized mix, P6G15 (i.e., 6% PCM and 15% Glass), demonstrated the best combined thermos-mechanical performance. It achieved a compressive strength of 29.8 Mpa. In terms of thermal conductivity there …

Nondestructive characterization methods for quality control of steel fiber reinforced concrete
… Specific focus was given to electrical surface resistivity, and specimens were designed to be representative of the final production elements, both in terms of fiber content and reinforcing steel dimensions. Moisture content and maturity were found to be major factors that affected the …

Development and Scaling up of Oxide Buffer Architectures on Flexible Substrates for Efficient and Application-Derived Growth of REBCO Thin Films
… high-frequency applications because of their low surface resistivity, high-quality factor (Q-factor), and low signal-to-noise ratio (SNR), which are essential for ensuring high-quality signal transmission. This study aims to improve the Jc and processing efficiency of REBCO to support the …

Durable high early strength concrete
… chloride dosage used in the study. Furthermore, surface resistivity tests for mixtures containing calcium chloride could result in erroneous measurements. Only one mixture satisfied the maximum expansion and minimum relative dynamic modulus of elasticity required by KDOT. Some ACI relationships …

Metal/polymer interactions
… films have been obtained which feature a surface or near-surface layer of copper metal or copper oxide as the conductive medium. The surface resistivity of the composites is lowered up to ten orders of magnitude relative to unmodified polyimide films. However, in many cases, the …

Aquifer Characterization in the Blue Ridge Physiographic Province
… flow. Recent acquisition of two-dimensional surface resistivity profiles collected using a variety of array techniques combined with borehole geophysical logs revealed new insights into this geologically complex province. Dipole-dipole arrays were particularly important in gathering high …

Explosive Safety with Regards to Electrostatic Discharge
Static charge is something that most individuals recognize as something that happens when they walk across a carpet, touch their refrigerator and get shocked. Most people seldom recognize that a shock due to static charge, or properly called, Electrostatic Discharge (ESD) is a phenomenon that has …

Theoretical study of Kondo effect and related transport properties in topological insulator systems
… covers two topics: the Kondo effect on the surface of a bulk topological insulator material and the Kondo effect in a topological insulator quantum dot. Other relevant background knowledge and theoretical techniques for the transport calculations are also discussed in the thesis. For the …

Novel etch studies and passivation techniques on InAs/GaSb superlattice based infrared detectors
… excess dark currents in the bulk and on detector surfaces. During SLS device fabrication the mesa delineation leads to discontinuity of the periodic crystal structure which results in formation of unsatisfied chemical bonds on the etched surfaces and hence enhancing the surface leakage currents. …
