Nanoscale electropolishing of high-purity nickel with an ionic liquid

引用

International Journal of Minerals,Metallurgy and Materials 2019年第5期26卷 649-656页

作者： jon Derek Loftis Tarek M.Abdel-Fattah Applied Research Center at Thomas Jefferson National Accelerator Facility and Department of Molecular Biology and Chemistry at Christopher Newport University Department of Physical Sciences Virginia Institute of Marine Science College of William and Mary Faculty of Sciences Alexandria University

High purity(>99.9% composition) nickel metal specimens were used in electropolishing treatments with an acid-free ionic liquid electrolyte prepared from quaternary ammonium salts as a green polishing solution. Voltammetry and chronoamperometry tests were conducted to determine the optimum conditions for electrochemical polishing. Atomic force microscopy(AFM) revealed nanoscale effectiveness of each polishing treatment. Atomic force microscopy provided an overall observation of the material interface between the treated and unpolished regions. Surface morphology comparisons summarized electrochemical polishing efficiency by providing root-mean-square roughness averages before and after electrochemical polishing to reveal a mirror finish six times smoother than the same nickel metal surface prior to electropolishing. This transition manifested in a marked change in root-mean-squared roughness from 112.58 nm to 18.64 nm and producing a smooth mirror finish. Finally, the mechanism of the ionic liquid during electropolishing revealed decomposition of choline in the form of a transient choline radical by acceptance of an electron from the nickel-working electrode to decompose to trimethylamine and ethanol.

Modern Memoir and Esoteric Aesthetics: The Inauthentic Context of Zora Neale Hurston's"Ring of Thieves"

Cecily Swanson argues that“modernism's Gurdjieff craze in fact played a surprising role in the development of an overlooked canon of popular autobiographies:Muriel Draper's memoir,Music at Midnight;Margaret Anderson's memoir,My Thirty Years'War;and Kathryn Hulme's autobiographical novel,We Lived As Children.”Swanson reads Draper,Anderson,and Hulme because they wrote as esotericists,while she divorces the memoirs from any overt esoteric influences,contents,or *** is no need to search further for the source of the mode of the popular autobiographies by Anderson and Draper than what of Loos's novel comes through the Peggy Hopkins Joyce/Zora Neale Hurston ***,Men,and Me appears near the commencement of a line of esoteric memoirs that becomes visible in the best-selling works by Draper and Anderson but then continues expansively.

Chaotic genetic patchiness （CGP） refers to surprising patterns of spatial and temporal genetic structure observed in some marine species at a scale where genetic variation should be efficiently homogenized by gene flow via larval dispersal. Here we review and discuss 4 mechanisms that could generate such unexpected patterns： selection, sweepstakes reproductive success, collective dispersal, and temporal shifts in local population dynamics. First, we review examples where genetic differentiation at specific loci was driven by diversifying selection, which was historically the first process invoked to explain CGP. Second, we turn to neutral demographic processes that may drive genome-wide effects, and whose effects on CGP may be enhanced when they act together. We discuss how sweepstakes reproductive success accelerates genetic drift and can thus generate genetic structure, provided that gene flow is not too strong. Collective dispersal is another mechanism whereby genetic structure can be maintained regardless of dispersal intensity, because it may prevent larval cohorts from becoming entirely mixed. Theoretical analyses of both the sweepstakes and the collective dispersal ideas are presented. Finally, we discuss an idea that has received less attention than the other ones just mentioned, namely temporal shifts in local population dynamics.
