Main Determinants For Iii-V Metal-Oxide-Semiconductor Field-Effect Transistors (Invited), P. D. Ye

Birck and NCN Publications

Lacking a suitable gate insulator, practical GaAs metal-oxide-semiconductor field-effect transistors (MOSFETs) have remained all but a dream for more than four decades. The physics and chemistry of III-V compound semiconductor surfaces or interfaces are problems so complex that our understanding is still limited even after enormous research efforts. Most research is focused on surface pretreatments, oxide formation, and dielectric materials; less attention is paid to the Ill-V substrate itself. The purpose of this article is to show that device physics more related to III-V substrates is as important as surface chemistry for realizing high-performance III-V MOSFETs. The history and present …

Β-Diketonate, Β-Ketoiminate, And Β-Diiminate Complexes Of Difluoroboron, Felipe P. Macedo, Chengeto Gwengo, Sergey V. Lindeman, Mark D. Smith, James R. Gardinier

Chemistry Faculty Research and Publications

A series of β-diketonate, keto(aryl)iminato, and β-bis(aryl)iminato complexes of difluoroboron, twenty in total, have been prepared to assess the impact of chelate ring and aniline substitution on the structural, electrochemical, and photophysical properties of these ubiquitous chelates. DFT (B3LYP/6-31G*) calculations supplemented the experimental results and both demonstrated that replacing oxygen with the more electron-donating aniline groups serves to only fine-tune the electronic properties because both the HOMO and LUMO energies are affected by such substitution. The electronic properties of all compounds are most greatly influenced by the nature of the substituents bound to the carbon portion of the chelate ring. …

Dartmouth Scholarship

Background:

Worldwide, approximately two billion people are chronically infected with Toxoplasma gondii with largely unknown consequences.

Methods:

To better understand long-term effects and pathogenesis of this common, persistent brain infection, mice were infected at a time in human years equivalent to early to mid adulthood and studied 5–12 months later. Appearance, behavior, neurologic function and brain MRIs were studied. Additional analyses of pathogenesis included: correlation of brain weight and neurologic findings; histopathology focusing on brain regions; full genome microarrays; immunohistochemistry characterizing inflammatory cells; determination of presence of tachyzoites and bradyzoites; electron microscopy; and study of markers of inflammation in serum. …

Muc4 And Muc5ac Are Highly Specific Tumour-Associated Mucins In Biliary Tract Cancer., W. R. Matull, F. Andreola, A. Loh, Z. Adiguzel, M. Deheragoda, U. Qureshi, Surinder K. Batra, D. M. Swallow, S. P. Pereira

Journal Articles: Biochemistry & Molecular Biology

Alterations in epithelial mucin expression are associated with carcinogenesis, but there are few data in biliary tract cancer (BTC). In pancreatic malignancy, MUC4 is a diagnostic and prognostic tumour marker, whereas MUC5AC has been proposed as a sensitive serological marker for BTC. We assessed MUC4 and MUC5AC expression in (i) prospectively collected bile and serum specimens from 72 patients with biliary obstruction (39 BTC) by real-time reverse transcriptase-PCR (qPCR) and western blot analysis, and (ii) 79 archived biliary tissues (69 BTC) by immunohistochemistry. In bile, MUC4 protein was detected in 27% of BTC and 29% of primary sclerosing cholangitis (PSC) …

Toward The Synthesis Of Nuclease Models., Enni Nina Fomumbod

Electronic Theses and Dissertations

Nucleases are enzymes that can specifically recognize nucleic acids and hydrolyze their phosphodiester bonds effectively. As is the case with many hydrolases, nucleases often carry one or more metal centers. Cooperation between such metal centers and other interactions involving general acid-base activities are believed to be essential in multifunctional catalyses. Combination of such interactions in model compounds often resulted in larger than additive effects.

This work is aimed at synthesizing nuclease models that combine the ability to recognize phosphate groups and/or nitrogen bases of DNA together with the ability to catalyze phosphodiester hydrolysis. These models were designed to achieve optimum …

Atomic-Layer-Deposited Nanostructures For Graphene-Based Nanoelectronics, Yi Xuan, Y Q. Wu, T Shen, Minghao Qi, Michael A. Capano, James A. Cooper, P. D. Ye

Birck and NCN Publications

Graphene is a hexagonally bonded sheet of carbon atoms that exhibits superior transport properties with a velocity of 10(8) cm/s and a room-temperature mobility of >15 000 cm(2)/V s. How to grow gate dielectrics on graphene with low defect states is a challenge for graphene-based nanoelectronics. Here, we present the growth behavior of Al2O3 and HfO2 films on highly ordered pyrolytic graphite (HOPG) by atomic layer deposition (ALD). To our surprise, large numbers of Al2O3 and HfO2 nanoribbons, with dimensions of 5-200 nm in width and >50 mu m in length, are observed on HOPG surfaces at growth temperature between …

Formaldehyde Over North America And The North Atlantic During The Summer 2004 Intex Campaign: Methods, Observed Distributions, And Measurement‐Model Comparisons, Alan Fried, James G.

A tunable diode laser absorption spectrometer (TDLAS) was operated on the NASA DC‐8 aircraft during the summer INTEX‐NA study to acquire ambient formaldehyde (CH₂O) measurements over North America and the North Atlantic Ocean from ∼0.2 km to ∼12.5 km altitude spanning 17 science flights. Measurements of CH₂O in the boundary layer and upper troposphere over the southeastern United States were anomalously low compared to studies in other years, and this was attributed to the record low temperatures over this region during the summer of 2004. Formaldehyde is primarily formed over the southeast from isoprene, and isoprene …

Palaeoclimate Research In Villars Cave (Dordogne, Sw-France), Dominique Genty

International Journal of Speleology

Villars Cave is a typical shallow cave from South-West France (45.44°N; 0.78°E; 175 m asl) that has provided several speleothem palaeoclimatic records such as the millennial scale variability of the Last Glacial period and the Last Deglaciation. Monitoring the Villars cave environment over a 13-year period has helped in the understanding of the stable isotopic speleothem content and in the hydrology. For example, it was demonstrated that most of the calcite CaCO₃ carbon comes from the soil CO₂, which explains the sensitivity of the δ¹³C to any vegetation and climatic changes. Drip rate monitoring, carried …

Development Of Novel Liquid Chromatography-Electrospray Tandem Mass Spectrometry Approaches For The Structural Characterization Of Brevetoxins Including In Vitro Metabolites, Weiqun Wang

LSU New Orleans Theses and Dissertations

Brevetoxins are natural neurotoxins that are produced by “red tide” algae. In this study, brevetoxin-1 and brevetoxin-2 were incubated with rat liver hepatocytes and rat liver microsomes, respectively. After clean-up steps, samples were analyzed by liquid chromatography-electrospray mass spectrometry (LC-ES-MS). Two metabolites were found for brevetoxin-1: brevetoxin-1-M1 (MW 900 Da), formed by converting one double bond in the E or F ring into a diol; and brevetoxin-1-M2 (MW 884 Da), a hydrolysis product of brevetoxin-1 involving opening of the lactone ring. The incubation study of brevetoxin-2 found two metabolites. Brevetoxin-2-M1 (MW 912 Da) was elucidated by negative mode LC-MS/MS to …

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.
