Abstract:
Abstract The measurements of vacuum arc current parameters at the threshold current were made. The threshold currents for Cu, W, graphite cathodes were measured. It was shown that the current that vacuum arc chops with, has a statistical distribution. The vacuum arc current chopping is accompanied with significant ion current burst. The ion current of W and Cu cathodes contains intensive peaks with 30-50 ns duration. It was shown that the cathode materials that have intense peaks have a significant threshold current.

Abstract:
Microplastics (MPs) can adsorb heavy metals and metalloids and may cause a potential health hazard. Precise measurements of their size, shape, composition, and concentration at a single-MP level are important to evaluate their potential toxicity and identify their original source. However, current single-MP analytical methods such as micro-Raman spectroscopy and scanning electron microscopy have low throughput. Therefore, in this study, we applied the ion current sensing method, which has been used for single cell analysis, to single-MP analysis and examined whether size measurement and compos

These measurements are carried out for Ar+ ion beam current in the range of 20–90 mA and energy in the range of 850–1650 eV. Current density profiles near the extraction plane of the ion source are obtained by Abel inversion of the profiles of current measured using the parallel wires. In addition, the Faraday cup array provides radial profiles of ion current density at two different locations along the beam axis. A numerical mode

AbstractIn this paper we investigate methods to characterize angular current density from atomically defined gas field ion sources. We show that the ion beam emitted from a single apex atom is described by a two-dimensional Gaussian profile. Owing to the Gaussian shape of the beam and the requirement to collect the majority of the ion current, fixed apertures have inhomogeneous illumination. Therefore, angular current density measurements through a fixed aperture record averaged angular current density.

In the majority of applications using lithium-ion batteries, batteries are exposed to some harmonic content apart from the main charging/discharging current. The understanding of the effects that alternating currents have on batteries requires specific characterization methods and accurate measurement equipment. The lack of commercial battery testers with high alternating current capability simultaneously to the ability of operating at frequencies above 200 Hz, led to the design of the presented experimental setup.

Abstract:
Abstract The importance of dissolution of MnS inclusions in environmentally assisted cracking (EAC) of pressure vessel steels in high temperature water is well recognized. However, no direct measurement of the crack tip chemistry that develops during EAC has ever been performed, and only estimates exist for the dissolution rate of MnS and the resulting sulfur levels in the crack. In this manuscript, microsampling of the crack tip solution in A533B low alloy steel (0.013% S) exposed to constant and cyclic loading in 288°C water under various test conditions has been used to obtain direct measur

Abstract:
Abstract Laboratory evaluations were carried out on a series of anode materials which could be used for sacrificial cathodic protection of reinforced concrete bridge decks. These included aluminum, magnesium, and zinc alloys. Anodes were fabricated into test coupons and coupled to small lengths of reinforcing steel. The anode/steel couples were placed in simulated concrete environments consisting of sealed containers filled with silica sand treated with a mixed alkali solution containing 6 kg/m3 of chloride ion by volume of sand. The treated sands were dried to obtain resistivities of 23,100 a

Abstract:
The combined deliverables provide tools for incorporating real time pipe current measurements into a remote monitoring protocol to help in an integrated external corrosion management plan for cathodically protected pipelines. The use of continuous remotely collected pipe current measurements optimizes the corrosion protection and improves response time to upset conditions that might otherwise compromise the corrosion control.

Abstract:
Prior research leading to the development of predictive electromagnetic coupling computer codes has shown that the coating conductance is the principal factor in determining the response of a pipeline to magnetic induction transmission line. Under power line fault conditions, a high voltage may stress the coating causing a significant change in its conductance, and hence, the coupling response. Based upon laboratory experimentation and analysis, a model has been developed which allows prediction of the modified coating characteristics when subjected to high voltages during fault situations.

Full text
Abstract:
SMA is to be designed based on SMA volumetric properties in terms of air voids content (Va), voids in the mineral aggregate (VMA), and adequate stone-on-stone contact. For construction quality assurance (QA) purposes, INDOT currently accepts SMAs based on aggregate gradation and asphalt binder content. Thus, there is a discrepancy between SMA design criteria and construction acceptance. To better align design and construction, it is necessary to consider SMA volumetric properties in the use of QA. For HMA mixtures, INDOT has already transitioned from volumetric QA acceptance procedures to PWL.

Full text
Abstract:
It is accepted that many situations exist on pipelines where a significant length of the pipeline (typically 2000 ft to 5 miles) is either totally inaccessible or access is so difficult or expensive that monitoring is not done at the required frequency. The need for finding a technique to allow the corrosion engineer to monitor CP levels of inaccessible locations from an accessible remote location has therefore been identified. A study to investigate all possible techniques available to achieve the above objective and to analyze typical scenarios requiring this approach has therefore been unde

Full text
Abstract:
During a prior research program, a spiking phenomenon was identified that prevented the measurement of the off potential directly from the pipe-to-soil potential waveform. Furthermore, the spike made it impossible to measure an off potential during current interruption for some period of time following interruption. In recent years, there has been discussion that the spike in the pipe-to-soil potential waveform affects the ability of the CP system to mitigate corrosion. In addition, the increased significance that has been placed on off-potential measurements within the industry has made it im
