An optimization study was done using a multivariate experimental design including the following variables: pH, H2O2 flow rate, UV-lamp exposure time, average temperature, average solar power and initial concentrations of Fe(II) and oxalic acid.
After cooling, the photoresist was placed into a collimated UV lamp for exposure, and the film mask with the designed pattern was placed on top.
When bacterial bioaerosols were simultaneously exposed to UV irradiation and thermal energy for less than 1.05 s, more than 99% of S. epidermidis bioaerosols were inactivated at 120 °C with exposure to one UV lamp and at 80 °C with exposure to two UV lamps; and 93.5% and 98.5% of B. subtilis bioaerosols were inactivated at 280 °C with exposure to one and two UV lamps, respectively.
Degradation of ClO2 gas under dark, UV-A and fluorescent lamp exposure was found to follow a first-order reaction.
The aim of this work was to determine the diffusion coefficient for ClO2 gas in air and reaction rates under dark, UV-A and fluorescent lamp exposure.
UVGI system performance and costs to implement and operate the system depend greatly on the output of the UV lamps and the exposure time, which are affected by the temperature and the velocity of the air passing through the UVGI device.
Then, using the obtained WCDs as a reducing agent, Ag-Pal nanocomposites were fabricated by ultraviolet (UV) radiation method, which is a simple and green process (90 min exposure to a UV lamp).
In addition, hydrogel polymerizations were realized through sample radiation exposure using a UV lamp with the emission peak centered at 365 nm (VILBER LOURMAT 230 V 50/60 Hz, 365 nm, 9 W).
For most samples, a glass counter substrate was then added and the epoxy layer was cured by exposure to a UV lamp for 1 3 h.
After 30 mins exposure from a handheld UV lamp (short wave, 254 nm) at a distance of 10 cm away from samples, the proteins were separated on SDS-PAGE, stained with Coomassie, and subjected to fluorography.
The UV irradiation was carried out with a UV lamp source, not with SSR.
