Abstract:

Carbon dioxide (CO 2 ) sequestration in subsurface reservoirs is important for limiting atmospheric CO 2 concentrations. However, a complete physical picture able to predict the structure developing within the porous medium is lacking. We investigate theoretically reactive transport in the long-time evolution of carbon in the brine–rock environment. As CO 2 is injected into a brine–rock environment, a carbonate-rich region is created amid brine. Within the carbonate-rich region minerals dissolve and migrate from regions of high-to-low concentration, along with other dissolved carbonate species

Abstract:

The impact of dissolved oxygen (O2) on cobalt (Co) corrosion in dilute HF (dHF) solution was studied. It was confirmed that Co etch rate was enhanced as the amount of dissolved O2 in the HF solution increased. The Co etch rate was also found to increase radially outward when performed on a single-wafer spin process in atmospheric air due to the uptake of O2 during the dispense process. The galvanic corrosion of Co was investigated with two types of structures with a Co/Cu interface in different dissolved O2 concentrations, i.e. (1) Co bump structures on Cu and (2) Cu lines with a Co/TaN liner/

Abstract:

Syngas fermentation is a promising technique to produce biofuels using syngas obtained through gasified biomass and other carbonaceous materials or collected from industrial CO-rich off-gases. The primary components of syngas, carbon monoxide (CO) and hydrogen (H2), are converted to alcohols and other chemicals through an anaerobic fermentation process by acetogenic bacteria. Dissolved CO and H2 concentrations in fermentation media are among the most important parameters for successful and stable operation. However, the difficulties in timely and precise dissolved CO and H2 measurements hinder

Abstract. Cobalt (Co) is an important bioactive trace metal that is the metal cofactor in cobalamin (vitamin B12) which can limit or co-limit phytoplankton growth in many regions of the ocean. Total dissolved and labile Co measurements in the Canadian sector of the Arctic Ocean during the U.S. GEOTRACES Arctic expedition (GN01) and the Canadian International Polar Year GEOTRACES expedition (GIPY14) revealed a dynamic biogeochemical cycle for Co in this basin. The major sources of Co in the Arctic were from shelf regions and rivers, with only minimal contributions from other freshwater sources

Abstract:

Abstract — Transformer oil is very important because it functions as a coolant and also as an insulator. In transformer oil there are dissolved gases that can cause failure of the transformer due to gas failure (fault gas). This research was conducted to determine the condition of transformer oil by analyzing the results of the Dissolved Gas Analysis (DGA) test. The DGA (Dissolved Gas Analysis) test is used to determine the type of failure in a transformer that has been operating for years. The DGA test is carried out by monitoring fault gases such as H2, CH4, CO, CO2, C2H4, C2H6, C2H2, O2, N2

Abstract:

In this work, the permeability of high performance composite coating (HPCC) and its containing layers fusion bonded epoxy (FBE) and middle density polyethylene (MDPE) to dissolved CO2 was investigated. The obtained results showed that the permeability to dissolved CO2 of HPCC, FBE, and MDPE are in order of HPCC<FBE<MDPE, the corresponding values of three coatings are 1.27 × 10-11 mol/atm⋅m⋅s, 1.54 × 10-11, and 3.51×10-10 mol/atm⋅m⋅s, respectively. The measurement methodology of dissolved CO2 permeability on organic coatings is feasible based on the present work.

Fluctuations were found in water temperature, pH, dissolved oxygen, free CO and alkalinity. Free CO and alkalinity exhibited a negative relationship with the temperature. Abundance of plankton also showed a distinct diurnal variation.

The percentage of CO2 in the mixture, and the flow rate of the mixture (representing agitation) have important effects on the microalgae biomass yield. However, the percentage recovery of CO2 as microalgae biomass was very low in all cases, indicating that most of the sparged CO2 did not dissolve in the POME and was not sequestered by the microalgae but has in fact escaped with the bubbles into the head-space and out into the atmosphere.

Abstract:

The electrochemical corrosion resistance of nanostructured hardmetals with grain sizes dWC < 200 nm was researched concerning Co content and the chemical nature of the Co binder. Fully dense nanostructured hardmetals with the addition of grain growth inhibitors GGIs, VC and Cr3C2, and 5 wt.%Co, 10 wt.%Co, and 15 wt.%Co were developed by a one cycle sinter-HIP process. The samples were detailly characterized in terms of microstructural characteristics and researched in the solution of H2SO4 + CO2 by direct and alternative current techniques, including electrochemical impedance spectroscopy.

Abstract:

The properties of a conjugated copolymer (CP), poly[(9,9-Dioctyl-2,7-divinylenefluorenylene)-alt-co-(2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylene) (PDVF-co-MEH-PV), were investigated in the presence of graphene oxide (GO) and reduced graphene oxide (rGO) using absorption, fluorescence, laser, and time-resolved spectroscopy. CPs are usually dissolved in low-polar solvents. Although GO does not dissolve well, rGO and PDVF-co-MEH-PV dissolve in chloroform due to their oxygen acceptor sites. Hence, we studied rGO/PDVF-co-MEH-PV (CP/rGO), performing all experiments and simulations in chloroform. We

This work was to study the dissolved CO in solution phase by using rotating disk electrodes and the solution phase CO demonstrate the limiting currents dependence of rotating speeds. Gold and gold-platinum metals clusters are used in glassy carbon supported rotating disk electrode for electrochemical oxidation of the solution phase CO. Small metal clusters and Au-Pt alloy effects are observed in the measurements. The comparison of microelectrode and RDE study of solution phase CO electrochemical oxidation is confirmed the limiting currents dependence of the boundary layers concentrations.

To produce over 99.9% of high-purity Al from Al–Fe alloy containing Al6Fe and Al–Fe–Si alloy containing β-AlFeSi by electrorefining, their anodic dissolution and cathodic electrodeposition characteristics were investigated in an EmImCl–AlCl3 ionic liquid electrolyte at 323 K. Constant potential electrolysis showed that Fe dissolved from Al–Fe anode at 0.7 V vs Al/Al(III) and from Al–Fe–Si anode at 1.4 V, and was co-deposited with Al on the cathode. Notably, anodic dissolution potential of Fe was changed by forming β-AlFeSi, and Si did not dissolve from β-AlFeSi at either potential. A combinati

Abstract. This paper presents the results of a two-year field campaign to determine the spatial and temporal variability of groundwater interaction with surface waters in two Cretaceous Chalk catchments (the Pang and Lambourn) in the Upper Thames in Berkshire, UK, based on measurement of dissolved carbon dioxide (CO2). Average stream water concentrations of dissolved CO2 were up to 35 times the concentration at atmospheric equilibrium. Mean groundwater concentrations of 85 and 70 times the atmospheric equilibrium were determined from borehole water sampled in the Pang and Lambourn respectively

The tasks of the work included a detailed coverage of the methodological approach “headspace equilibration” to the study of the concentration of dissolved CO₂in soil and surface waters, as well as the assessment of the range of CO₂concentrations in waters of different genesis in the landscapes of the north of Western Siberia.

Abstract:

For PEM fuel cell operation, high-purity hydrogen gas containing only trace amounts of carbon monoxide is a prerequisite. The water–gas shift reaction (WGSR) is an industrially applied mature operation mode to convert CO with H2O into CO2 (making it easy to separate, if necessary) and H2. Since the WGS reaction is an exothermic equilibrium reaction, low temperatures (below 200 °C) lead to full CO conversion. Thus, highly active ultra-low-temperature WGSR catalysts have to be applied. A homogeneous Ru SILP (supported ionic liquid phase) catalyst based on the precursor complex [Ru(CO)3Cl2]2 has

The vertical distribution of total dissolved Co (dCo) was similar to soluble reactive phosphate (PO43-), with dCo and PO43- showing a significant correlation throughout the water column (r2=0.87). A strong seasonal signal for dCo was observed, with most spring samples having concentrations ranging from ~45–85 pM, whereas summer dCo values were depleted below these levels by biological activity.
