Catalytic Enhancement of Singlet Oxygen for Hybrid Electric Discharge Oxygen-Iodine Laser Systems
We are investigating catalytically enhanced production of singlet oxygen, O2(aΔg), observed by reaction of O2/He discharge effluents on an iodine oxide film surface in a microwave discharge-flow reactor at 320 K. We have previously reported a two-fold increase in the O2(a) yields by this process, and corresponding enhancement of I(P1/2) excitation and small-signal gain upon injection of I2. In ...
متن کاملA Mems Singlet Oxygen Generator
The design, creation, and demonstration of a singlet oxygen generator (SOG) that operates on the microscale are presented. The micro singlet oxygen generator (μSOG) chip creates singlet delta oxygen (O2(Δ)) in an array of packed bed reaction channels fed by inlets with pressure drop channels to equalize flow. An integrated capillary array separates the liquid and gas byproducts, and microscale ...
متن کاملMicroscale Singlet Oxygen Generator for MEMS-based cOIL Lasers
Conventional chemical oxygen iodine lasers (COIL) offer several important advantages for materials processing, including short wavelength (1.3 μm) and high power. However, COIL lasers typically employ large hardware and use reactants relatively inefficiently. This project is creating an alternative approach called microCOIL. In microCOIL, most conventional components are replaced by a set of si...

Singlet oxygen (O2) is a higher energy state molecular oxygen species. It is one of the most active intermediates involved in chemical and biochemical reactions. To fully appreciate the reactivity of O2, it is necessary to understand its physical and chemical nature. This paper reviews the generation, quenching and detection of O2. Its properties, possible chemical reactions are presented as we...
متن کاملPulsed diode laser-based monitor for singlet molecular oxygen.
Photodynamic therapy (PDT) is a promising cancer treatment. PDT uses the affinity of photosensitizers to be selectively retained in malignant tumors. When tumors, pretreated with the photosensitizer, are irradiated with visible light, a photochemical reaction occurs and tumor cells are destroyed. Oxygen molecules in the metastable singlet delta state O2(1Delta) are believed to be the species th...
