Electrochemical Oxidation of Perfluorooctanesulfonate by Magnéli Phase Ti4O7 Electrode in the Presence of Trichloroethylene

Received: 02 November 2020;  Published: 29 December 2020;  doi: 10.21926/aeer.2004006

Abstract

This study examined the degradation of perfluorooctanesulfonate (PFOS) in electrochemical oxidation (EO) processes in the presence of trichloroethylene (TCE). The EO experiment was performed in a gas-tight reactor using Magnéli phase titanium suboxide (Ti4O 7) as the anode. The experimental data demonstrated that 75% of PFOS (2 μM) was degraded at 10 mA/cm2 current density in 30 min without TCE present in the solution, while the presence of 76 μM TCE apparently inhibited the degradati [...]

How to Prioritize Voluntary Dietary Modification

Received: 03 August 2020;  Published: 25 December 2020;  doi: 10.21926/aeer.2004005

Abstract

Environmentally motivated voluntary diet modifications are the focus of much research and public discourse. Yet the nuanced multi-faceted, multi-dimensional nature of agriculture-earth interactions, and limited public environmental knowledge likely combine to undermine the efficacy of environmentally motivated dietary shifts, squandering limited good will. To counter this, here I devise two related indices for crudely estimating importance of various environmental impacts of alternative dietary choices. Based on th [...]

Climate Cloud Model Forecast Verification-an Engineering Perspective

Received: 13 September 2020;  Published: 24 November 2020;  doi: 10.21926/aeer.2004004

Abstract

The processes relevant to the verification of cloud forecasts generated by climate models are discussed from an engineering perspective. These processes include an assessment of cloud product requirements to be evaluated, the creation of a verification test plan including procedures and data to be analyzed, the development of independent sources of validation or truth datasets, and the quantitative comparisons between the cloud forecast products and the truth data needed to establish model performance. The engineer [...]

Impact of COVID-19 Lockdowns and Australian Bushfires on Aerosol Loading over the Downwind Oceanic Regions

Received: 21 August 2020;  Published: 23 November 2020;  doi: 10.21926/aeer.2004003

Abstract

Nearly 40 years of aerosol optical thickness (AOT) climate data record (CDR) from AVHRR satellite observations over the global ocean is used to study the impact of COVID-19 lockdowns and Australian bushfires on aerosol loading over downwind oceanic regions. Recent similar impact studies, by contrast, were mainly focused on the urban and suburban areas near the emission sources. AOT is used as a proxy for aerosol loading in our study. We found that AOT variations due to anthropogenic emission reduction during the lo [...]

Estimating the Intensity of Hurricanes from Historical Radar Data Using the Hyperbolic-logarithmic Approximation of Spiral Rainbands

Received: 28 July 2020;  Published: 10 November 2020;  doi: 10.21926/aeer.2004002

Abstract

To increase the amount of information on the intensities of tropical cyclones (TC) used in climate research, the possibility of additional estimates of the intensity of a TC by exploring historical data of conventional (non-Doppler) airborne and coastal radars is considered. Based on the hyperbolic-logarithmic spiral (HLS) model of the streamline in the TC, an assessment of the maximum wind speed in hurricanes Cleo (1958), Carolina (1975) and Alicia (1983) was made. Literature sources containing radar signatures of [...]

Heavy Metal Concentration and Health Risk Assessment of Selected Fruits Sold in Jos Metropolis

Received: 27 February 2021;  Published: 12 May 2021;  doi: 10.21926/acr.2102013

Abstract

The present study investigated the level of heavy metals in selected fruits sold commonly in Jos, Nigeria. The fresh fruits (Avocado pear, Black currant, Egg Plant, Golden melon, and Soursop) were purchased from five major markets (Terminus, Farin Gada, Building materials, Bukuru, and Fobur) in Jos. Each fruit sample was collected in triplicate and analyzed using standard procedures. The concentration of heavy metals (Fe, Cu, As, Cd, Zn, Pb, Mn, and Cr) was determined using Graphite Furnace Atomic Absorption Spectr [...]

Effect of Convective Mixing Process on Storage of CO2 in Saline Aquifers with Layered Permeability

Received: 19 October 2020;  Published: 25 February 2021;  doi: 10.21926/acr.2101012

Abstract

Convective mixing of free-phase CO2 and brine in saline aquifers is an established technique to accelerate the CO2 dissolution process. Correct estimation of the convection onset time and rate of CO2 dissolution into brine are two crucial parameters regarding safety issues, as the timescale for dissolution corresponds to the same time over which the free-phase CO2 has a chance to leak out from the storage site. In real practice, underground formations are heterogeneous with a layered structure, but the convective m [...]

Theoretical investigation of the single and double ionization spectra of M(CO)6, M = W and Cr

Received: 26 April 2020;  Published: 14 December 2020;  doi: 10.21926/acr.2004010

Abstract

In this work, we study the single and double ionization spectra of the , with complexes by applying the four-component algebraic diagrammatic construction and Fock-space coupled cluster methods to extend earlier studies based on less demanding approaches. The computed single and double ionization potentials are in good agreement comparing with the available experimental results. The electronic structures of the cationic molecular systems are carefully investigated by computing accurately single and double ionizatio [...]
