Polymeric submicron optical ion-selective sensors

Creator:: Bychkova, Valeriya
Abstract:: Ion-selective polymeric optical sensors – ion optodes – are a promising alternative to ion-selective electrodes and fluorescent dyes for analytical and biological applications, e.g. extra- and intracellular measurements. They are non-toxic, highly selective robust probes for ionic fluxes monitoring. A large-scale fabrication of ion optodes using a solvent displacement method...

Approaches to the synthesis of methymycin

Creator:: Raghavan, Palaykotai Rajagopalan
Abstract:: Several approaches to the synthesis of methymycin were investigated. Segment A (39), containing functionality corresponding to C-9, 10, and 11 of methynolide was made in six steps from propionaldehyde in an overall yield of 37%. Oxidation of 34 with silver nitrate gave 35 which, upon hydroxylation with hydrogen peroxide, gave...

Substitutional Effects on the Electromechanical Properties of Lead-free, Piezoelectric (Na₀.₅Bi₀.₅)TiO₃-BaTiO₃ (NBT-BT)

Creator:: McQuade, Ryan R.
Abstract:: This work investigates the effect of cation substitution on the properties of the lead-free, solid solution (Na₀.₅Bi₀.₅)TiO₃-BaTiO₃ (NBT-BT). Substitution into NBT-BT increases disorder and increases the relaxor ferroelectric properties. These relaxor ferroelectric materials show large piezoelectric strains that can be utilized in actuator applications. Ceramic samples were prepared using standard...

Improvements in synthesis and response techniques of ion-selective sensors

Creator:: Pylypiuk, Nataliia
Abstract:: Two improvements to the established procedures for synthesis and response detection of ion-selective optical sensors (optodes) were introduced. The first improvement addresses the drawback of organic dye (optode-localized chromoionophore) photobleaching. This positively impacts fluorescence response and allows for (1) direct measurement of hydrogen ion activity upon binding with the dye,...

Study of simultaneous codeposition of metals at solid electrodes

Creator:: Yindepit, Somrat
Abstract:: As with many pairs of metals, the electrodeposition of Pb-Tl, Cu-Cd, and Cu-Ni at solid electrodes yielded partial polarization curves shifted from the polarization curves of the single metals. The curves for the more noble metals (Pb, Cu) were shifted negatively while the less noble metals'(Tl, Cd, Ni) curves were...

Aqueous chemistries for oxide electronics

Creator:: Meyers, Stephen T.
Abstract:: The variegated aqueous chemistries of metal cations are applied to the design and synthesis of non-toxic solution precursors suitable for additive printing of large-area oxide electronics. Polycondensation behaviors of aqueous Al+3 and PO4 +3 are manipulated in the deposition of atomically smooth amorphous aluminum oxide phosphate (AlPO) dielectric films. AlPO...

Transpacific transport of benzo[a]pyrene emitted from Asia

Creator:: Zhang, Y., Tao, S., Ma, J., and Simonich, S.
Abstract:: A global-scale three dimensional atmospheric transport and chemistry model was applied to simulate transpacific transport of Benzo[a]pyrene (BaP) emitted from Asia. The model results were compared with observations at six monitoring sites. The annual mean and seasonal variation of transport patterns and the contributions of different Asian source regions to...
