Analytical Methods Development for High-Throughput Photochemisty With Led Arrays
… and potassium tris(oxalato)ferrate(III) chemical actinometry. The results are analyzed using descriptive statistics and analysis of variance (ANOVA). The LEDs in the third generation array were shown to be statistically equivalent, with respect to light output, according to physical and chemical …

N2, O2, and NF3 Dissociation in a Low Frequency, High Density Plasma Source
… emission spectroscopy (OES), combined with Ar actinometry for various mixes of N2, O2, and NF3 feed gases with Ar at 400 sccm total flow rate in a low frequency (400 kHz), high pressure (4.0 Torr), inductively-coupled toroidal remote plasma source from MKS Instruments, operating at a power …

Characterization of rf cylindrical magnetron plasmas and reactive ion etching of silicon/silicon dioxide: Its effect on radiation damage and contamination
… optical emission spectroscopy and optical actinometry. Also the etch rates and etch profiles of Si/SiO$\sb2$ for 13.56MHz were studied for various conditions in CF$\sb4$/H$\sb2$ and CHF$\sb3$ plasmas as a function of magnetic field strength. The degree of radiation damage and contamination …

Chemical studies of plasma etchants used in integrated circuit manufacture
… thesis. Optical emission spectroscopy with argon actinometry was used as the principle plasma diagnostic. Statistical experimental design was used to model and compare Si and Si02 etch rates in CF4 and SF6 discharges as a function of flow, pressure and power. Etch mechanisms m both systems, …

Study of elementary reactions of combustion importance at elevated temperatures and pressures
… the reactor is determined by an accurate in situ actinometry based on the ozone formation in the presence of molecular oxygen. The reactions studied are OH + OH --> products (k_{OH+OH}), CH_3 + OH --> products (k_{CH3+OH}), CH_3 + CH_3 --> products (k_{CH3 + CH3}), and CH_3 +HO_2 --> products …

The aqueous photochemistry of 4-chlorophenol
… solution of 0.44 ± 0.1 has been determined by actinometry. The photolyses of 4-bromophenol and 4-iodophenol in neutral aqueous solution yield the same photoproducts as for 4-chiorophenol but with reduced quantum yields of 0.08 and 0.022 respectively. In oxygen-saturated solution the rate at …

Minimum Ultraviolet Light Dose Determination and Characterization of Stress Responses that Affect Dose for Listeria monocytogenes Suspended in Distilled Water, Fresh Brine, and Spent Brine
Foodborne illnesses caused by Listeria monocytogenes have long been associated with ready-to-eat (RTE) meats contaminated after the primary thermal process has been applied. It is believed that brine solutions used to chill cooked RTE products may serve as a reservoir for L. monocytogenes becoming …
