Preparation And Investigations On The Tio2 Nanotube Arrays For Cathodic Protection Of 316l Stainless Steel, Jing Li, Hong Yun, Chang-Jian Lin
Journal of Electrochemistry
A highly ordered TiO2 nanotube layer was fabricated by potentiostatic anodization of pure titanium in fluorinated electrolyte solutions. The structure and composition of the as-prepared TiO2 nanotubes were characterized by SEM and XRD.The TiO2 nanotubes show a stronger absorption in the ultraviolet(UV) light range. The performances of photogenerated cathodic protection and the photoelectrochemical response for the TiO2 nanotube layers under illumination and dark conditions were evaluated through the electrochemical measurements. It is found that the open-circuit potentials of 316 SS coupled with the TiO2 nanotubes layers shift negatively under UV light irradiation(λ<380nm). It is indicated that the TiO2 nanotubes arrays …380nm).>

Electrochemical Behavior Of Dill Pipe In 31%(By Mass) Nacl Solution Based New Type Inhibitor, Fu-Guo Liu, Min Du, Qing-Zhang Wang
Journal of Electrochemistry
The inhibitive effect of compound inhibitor including emulsifier(P), zinc sulfate, sodium polyphosphate, Glucose Gluconate was studied in 31% NaCl (by mass) solution. The inhibitory mechanism was analyzed by polarization curve and EIS. The results showed that the compound inhibitor was anodic-type inhibitor and its inhibitive effect on anodic and cathodal reaction was the most obvious at 200×10-6g·L-1. And the results of EIS revealed that the inhibition efficiency increased and the film formed on electrode surface was more and more compact with time. Inhibition mechanism was different with concentration of inhibitor.

Journal of Electrochemistry
When condensers with carbon steel waterbox and titanium tube structure were protected by SACP in an ocean beach power plant,while seawater were used to be cooling water,carbon steel was under-protected and Titanium was over-protected,because their protective potential are less than-0.85V(vs.SCE) and more than-0.75V(vs.SCE) separately.In order to optimize the SACP design,potential distribution of two materials must be obtained during the SACP process.In the lab,carbon steel waterbox and Titanium tube model(Q235-Ti model) were set up.A series of electrochemical techniques(steady polarization,galvanostatic charge technique)were used to obtain reasonable boundary condition and surface form of two materials during the SACP process.The experiments were carried out …

Research Of 2,2′-Dipyridine On Electroless Copper Plating Using Sodium Hypophosphite As Reductant, Bin Yang, Fang-Zu Yang, Ling Huang, Shu-Kai Xu, Guang-Hua Yao, Shao-Min Zhou
Journal of Electrochemistry
In the bath of the electroless copper plating using sodium hypophosphite as reductant, the effects of 2,2′-dipyridine on the deposition rate, anodic oxidation of sodium hypophosphite, cathodic reduction of copper ions, surface morphologies, structure and the existing status of the deposit components were examined. The results showed that, 2,2′-dipyridine hindered the electroless deposition.Experiments of liner sweep voltammetry (LSV) indicated that,as the addition of 2,2′-dipyridine to the electrolyte, the oxidation peak potential of sodium hypophosphite shifted to a more negative value but the peak current decreased; the reducing peak potential of copper ions moved to a more negative value whereas the …

Publishing Original Content In An Institutional Repository, Paul Royster
University of Nebraska-Lincoln Libraries: Faculty Publications
Institutional repositories (IRs) have been developed and promoted primarily as a means to re-publish scholarly content previously published elsewhere—usually in journals, festschriften, or collections of articles. This essay discusses the use of IRs as the originating publisher of materials not previously published elsewhere, and assesses their potential use as a viable “first resort” for scholarly publication and an already existing alternative to traditional commercial or university presses.
Construction Of A Calcium Matter-Wave Interferometer, Christopher Joseph Erickson
Construction Of A Calcium Matter-Wave Interferometer, Christopher Joseph Erickson
Theses and Dissertations
I describe the construction of a calcium matter-wave interferometer. The interferometer is based on a Ramsey-Borde scheme, and uses a thermal beam of atoms excited by an optical-frequency transition in calcium. In our experiment four pi/2 pulses of light are delivered to the atoms, which split and recombine the wave functions of the atoms. Our experimental design minimizes first-order Doppler shifts, and allows for the cancellation of systematic errors including phase shifts due to rotation and acceleration. I describe the individual components of the interferometer and its assembly. The requirements for the electronics used in the experiment as well as …

Longitudinal Data With Follow-Up Truncated By Death: Finding A Match Between Analysis Method And Research Aims, Brenda Kurland, Laura Lee Johnson, Paula Diehr
Longitudinal Data With Follow-Up Truncated By Death: Finding A Match Between Analysis Method And Research Aims, Brenda Kurland, Laura Lee Johnson, Paula Diehr
UW Biostatistics Working Paper Series
Diverse analysis approaches have been proposed to distinguish data missing due to death from nonresponse, and to summarize trajectories of longitudinal data truncated by death. We demonstrate how these analysis approaches arise from factorizations of the distribution of longitudinal data and survival information. Models are illustrated using hypothetical data examples (cognitive functioning in older adults, and quality of life under hospice care) and up to 10 annual assessments of longitudinal cognitive functioning data for 3814 participants in an observational study. For unconditional models, deaths do not occur, deaths are independent of the longitudinal response, or the unconditional longitudinal response averages …

Preheating In Derivatively-Coupled Inflation Models, Christian Armendariz-Picon, Mark Trodden, Eric J. West
Preheating In Derivatively-Coupled Inflation Models, Christian Armendariz-Picon, Mark Trodden, Eric J. West
Physics - All Scholarship
We study preheating in theories where the inflaton couples derivatively to scalar and gauge fields. Such couplings may dominate in natural models of inflation, in which the flatness of the inflaton potential is related to an approximate shift symmetry of the inflaton. We compare our results with previously studied models with non-derivative couplings. For sufficiently heavy scalar matter, parametric resonance is ineffective in reheating the universe, because the couplings of the inflaton to matter are very weak. If scalar matter fields are light, derivative couplings lead to a mild long-wavelength instability that drives matter fields to non-zero expectation values. In …
Literacy Education In School : Research Perspectives From The Past, For The Future, Peter Freebody
Literacy Education In School : Research Perspectives From The Past, For The Future, Peter Freebody
Australian Education Review
AER 52 aims to expand our understanding of the nature of literacy at a time when public and private lives have become increasingly literacy-dependent, and literacy demands more complex and sophisticated. This review of the research literature is guided by the view that what passes for effective literacy education will differ depending on language, culture, history and the technologies of communication and knowledge production. Section 1 describes the large body of research relating to the teaching and learning of literacy that emerges from a wide range of discipline bases. It details the complexities associated with defining literacy, and it outlines …

The Identification Of Factors Influencing The Diffusion Of An Assessment Innovation On A University Campus, Ann Louise Mccann
College of Education and Human Sciences: Dissertations, Theses, and Student Research
This study explored the extent of and reasons for the adoption of an innovation (REAL) on a university campus (MSU). REAL was an assessment system to improve teaching, student learning and accountability. A mixed methods approach was used, with an electronic survey of faculty (n = 568) and telephone interviews with adopters (n = 9). Using a stratified random sample from all eight colleges, the survey measured perceptions of REAL related to: relative advantage, trialability, result demonstrability, visibility, compatibility, complexity, image and voluntariness. The interview questions also explored the strategies of senior administrative support, collaborative leadership, flexible vision, staff development, …
New Ways To Collect Data In The Antarctic, Walker O. Smith, Vernon Asper
New Ways To Collect Data In The Antarctic, Walker O. Smith, Vernon Asper
Faculty Publications
Conducting Antarctic research is challenging. Not only is the environment difficult, given low temperatures, high winds, and ice cover, but also the availability of sampling platforms is limited. The U.S. National Science Foundation has only two vessels that can routinely operate in ice‐covered waters, the research vessel/icebreaker N.B. Palmer and the Antarctic research support vessel L.M. Gould. The restricted availability of vessels makes research operations difficult to schedule, especially during austral spring and summer. Traditional sampling methods (those confined to ships and moorings) have provided insights into distributions and processes in the Southern Ocean, but new research questions require new …
