How circumstellar discs affect mass accretion in Be X-ray binaries
… and best studied being the Hα line. The peak separations of the double peaked Hα emission line are measured, and along with the mass of the Be star and the inclination of the disc obtained from literature, are used to determine the Be disc radius. For single peaked Hα profiles the peak …

Metal metaphosphate complexes for redox flow batteries
… couples is 2.7 V which is the highest peak to peak separation reported in the literature to date.

Qualitative and quantitative assessment of UCM in PM2.5 of Bakersfield, CA.
… PM ₂.₅ . To quantify the overlapping UCM peaks, a method was developed for the deconvolution (peak separation) of the UCM. This enabled unique quantification of each UCM peak. The developed method was tested on several runs of a standard reference material for urban dust, which yielded …

Fast Fourier transform square wave voltammetry
… was shown to be an effective measure of peak height and its use in calibration curves was demonstrated. The real and imaginary spatial frequencies were shown to be sensitive measures of peak position. FFT square wave voltammetry was developed. The technique performs the current …

Near surface wear structure of ceramic components
… of phases and chemical species, (2) peak separation, (3) quantitative phase analysis, (4) intensity band simulation, and (5) line shape analysis, were applied to ceramic materials of silicon nitride, zirconia toughened alumina, fully and partially stabilized zirconia. A theoretical …

Synthesis, Characterization, and Mixed-Valence Studies of Conformationally Constrained Bisferrocenyl Complexes for the Study of Through-Space S***π; Interactions
… 1e⁻ redox processes for the ferrocenes where the separation of peaks is affected by both solvent and supporting electrolyte, suggesting significant electrostatic interaction which is further confirmed in the gas phase by UPS studies. To determine if these interactions could be observed at greater …

AUTOSEP-Automated Separation by Eluotropic Space Optimisation
This project is named “AUTOSEP-Automated separation by eluotropic space optimisation” using High Performance Liquid Chromatography, (HPLC). The term eluotropic space is defined as the design space, which includes all the chemical and instrumental changes that can be performed in a chromatographic …

Effect of applied fields on the optical properties of color centers
… the spin=orbit splitting (measurement of the peak separation of the resolved structure and measurement of the circular dichroism)~ and shows that the structure arises from a combination of a large spin=orbit coupling and a large non=cubic lattice vibrational interaction."

Electrochemical detection of chemical warfare agents
… it toward anodic direction. Anodic to cathodic peak separation were found to be within 62-88 mV indicating a quasi-reversible system. Hydrolysis of compound 1 resulted in the formation of tert-butyl 1’-methoxycarbonyl-1-ferrocenecarboxylic acid, Boc-NH-Fc-COOH, (11) which was coupled with …

Quantum discord, EPR steering and Bell-type correlations for secure CV quantum communications
… states. According to our method, the peak separation between the marginal distributions of one subsystem conditioned on two different outcomes of homodyne measurement conducted on the other subsystem is an indication of nonzero quantum discord. We implemented this method experimentally …

Novel biodegradable fibres for applications in tissue engineering and drug delivery
… having a machined topography characterised by a peak-peak separation of 91 mm and a peak height of 30 mm. Differential scanning calorimetery (DSC) analysis of as-spun fibres revealed the characteristic melting point of PCL at around 58°C and a % crystallinity of approximately 60%. The …

Metal(ii) schiff base complexes and the insulin-mimetic Studies on the oxovanadium(iv) complexes
… IR and 1H NMR. The appearance of two different peaks for each of the azomethine protons and phenolic protons confirm the asymmetry nature of the unsymmetrical Schiff bases. All the Schiff bases were successfully coordinated to oxovanadium (IV) ion to form the corresponding complexes. The …

Searches for Radio Transients using the Long Wavelength Array
… giant pulses at 74 MHz. Giant pulses with double-peak temporal structure have a shorter peak-to-peak separation compared to the average pulse. Once again, PSR B0950+08 appears to produce less frequent and weaker giant pulses than reported at 100 MHz. Giant pulses are identified with …
