Ionene and ionene alkyl sulfate stoichiometric complexes
Stoichiometric polyelectrolyte-surfactant complexes represent a type of comb-shaped polymers, in which every polymer chain unit has an electrostatically bound "side chain". These complexes are water-insoluble. In the solid state they assemble spontaneously into mesogenic structures. The …

Properties of off stoichiometric yttrium iron garnet
… However, RSM results show that the off-stoichiometric YIG film on (111) GGG substrates can remain fully strained in plane with thickness from 23 nm to 74 nm; while the samples on (001) GGG substrates show different degrees of relaxation in-plane depending on film thickness. Magnetic …

Phase Transformations in Nearly Stoichiometric Nickel-Manganese Alloys
The transformation behavior of Ni-Mn alloys in the vicinity of the equiatomic composition has been studied using transmission electron microscopy and diffraction, x-ray diffraction, optical microscopy, and electrical resistivity measurements. The transformation behavior was found to be markedly …

Identification and stoichiometric analysis of the monosomal translational complex
… for these proteins in this process.</p><p>This stoichiometric analysis gives us a dynamic view of how the composition of the translational complex changes in vivo. This application of stoichiometric analysis using AU-FDS should prove widely adaptable to the identification of protein complexes in …

Chemomechanics of non-stoichiometric oxide films for energy conversion
… (LIBs) are enabled by materials known as "non-stoichiometric oxides" that contain large concentrations of point defects such as oxygen or lithium vacancies. While this non-stoichiometry provides the essential functional properties of ionic conductivity or reactivity that make these materials …

A new theory of premixed flames in near-stoichiometric mixtures
… a new model of premixed flames in near-stoichiometric mixtures is derived. Unlike most previous theories, which are valid only for very lean or very rich, i.e. off-stoichiometric conditions, our model remains valid over the entire spectrum of mixture compositions, from lean to rich, …

Development of universal stoichiometric coefficients for modeling microalgal cultivation systems
… of generalizable model parameters, such as stoichiometric parameters – like those used in the International Water Association’s (IWA’s) Activated Sludge Models (ASMs). This work introduces universal stoichiometric coefficients for algal process modeling derived from the conserved enzymatic …

The structure and stability of expanding and converging near-stoichiometric flames
The stability of expanding and converging premixed flames is investigated theoretically. These configurations are inherently unsteady and represent simple examples of positively (expanding) and negatively (converging) stretched flames. A new model is employed in this study that incorporates both …

Cathodoluminescence of radiation damage, non-stoichiometric and impurity defects in cadmium telluride
The effects of atomic displacement, degree of nonstbichiometry and impurity doping on the liquid helium temperature cathodoluminescence of cadmium telluride have been investigated. Under such treatment the responses of the emissions have cast some doubt on the previously accepted significance of …

Optical modeling off-stoichiometric amorphous Al2O3 thin films deposited by reactive sputtering
… in thin film technology. Alumina/aluminum/off-stoichiometric thin films were deposited by the reactive sputtering, which enabled us to vary the composition of films by controlling the oxygen flow ratio fed into the deposition system. The composition of the films was investigated with X-ray …

ALPHA4BETA2 NEURONAL NICOTINIC ACETYLCHOLINE RECEPTOR LIGANDS: FROM SUBTYPE SELECTIVE TO STOICHIOMETRIC ISOPHORM SELECTIVE PARTIAL AGONISM.
This PhD thesis focuses on the study of the α4β2 nicotinic acetylcholine receptors (nAChRs). This dissertation is divided into two parts. The first part is centred on the design, synthesis, and biological evaluation of compounds selective for the orthosteric and unorthodox binding sites of the α4β2 …

Electrocaloric effects in multilayer capacitors of stoichiometric lead scandium tantalate with varying B‑site cation order
Multilayer capacitors (MLCs) of stoichiometric lead scandium tantalate (PbSc0.5Ta0.5O3 or PST) have been shown to generate large thermal changes (known as electrocaloric, or EC, effects) in response to large changes in applied electric fields sustained without breakdown. These MLCs represent a …
