Two azacrown ether appended iridium(III) complexes, 1 and 3, are described as probes for metal cations operating on oxidative-reduction electrochemiluminescence (ECL) with tri-n-propylamine as coreactant in acetonitrile. Complexes 1 and 3 exhibit a notable ECL sensing for Ba(2+) and Ag(+), respectively, through a 9-fold emission intensity enhancement and an unprecedented λmax(em) red shift. In ...
Electronic brachytherapy as adjuvant therapy for early stage breast cancer: a retrospective analysis
PURPOSE This multicenter, retrospective study evaluated treatment and clinical outcomes of patients with early stage breast cancer who received adjuvant high-dose rate (HDR) electronic brachytherapy (EBT) treatment post-lumpectomy using the Axxent(®) EBT system. Dosimetric data from the EBT treatment plans were compared with those based on iridium-192 HDR brachytherapy. MATERIAL AND METHODS M...
Potential dual-mode monopropellant/electrospray capable binary mixtures of hydroxyl ammonium nitrate with ionic liquid fuels [Bmim][NO3] and [Emim][EtSO4] are synthesized and tested for monopropellant ignition capability in a micro reactor setup. The setup is benchmarked using 30% hydrogen peroxide solution decomposed via silver catalyst. Results show similar trends, but variance in the quantit...
This paper presents the structural, magnetic properties, and spin moment cancelation phenomenon of zirconium oxide with a gradual change for Iridium. The density functional theory (DFT) is shown to be key feature properties solid materials treatment. It that small adjustment (less than 6%) allowed. Zr1-xIrxO2 crystal structure deformation leads compensation occurs at x=0.06. Spin orbital moment...
Molten Oxide Electrolysis (MOE) is a promising and laboratory-proven in-situ resource utilization technology for generating oxygen from lunar regolith simulant. Prior to this work, iridium metal was the only demonstrated suitable inert anode material, but its use had been limited to laboratory-scale testing owing to its extraordinarily high density, hardness, and cost. In the current work, elec...
Potential cycling in the range from -0.2 to +1.2 V is used for the electrodeposition of hydrous iridium oxide films onto a screen-printed electrode from a saturated solution of alkaline iridium(III) solution. The iridium oxide redox couple shows a stable and obvious reversible redox, with the formal potential being pH dependent in the range 1-14. The properties, stability and electrochemical pr...
We show results of the Lyon-Fedder-Mobarry (LFM) global MHD simulations of an event previously examined using Iridium spacecraft observations as well as DMSP and IMAGE FUV data. The event is chosen for the steady northward IMF sustained over a three-hour period during 16 July 2000. The Iridium observations showed very weak or absent Region 2 currents in the ionosphere, which makes the event fav...
