The results showed that the photolysis of ATE, BZB, MET, and ATO all followed pseudo-first-order kinetics, and their average photon quantum yields of the wavelength studied were 0.14×10 2 , 0.33×10 3 , 0.78×10 4 , and 0.24×10 4 mol einstein 1 , respectively. Singlet oxygen ( 1 ...

Additionally,the correlation among different S values obtained from different fitting wavelength ranges was significantly different suggesting that the S values in various wavelength ranges only indicated the tip of the iceberg of DOM characteristics instead of the entirety. Furthermore,the ratio of ...
After baking at 65 °C for 5′ and 95 °C for 20′, the wafer was exposed to 405 nm ultraviolet light (Shinu MST, Korea) with a 250 mJ dose and masked by the negative film mask (Han&All Tech, Korea). After this first round of exposure, the wafer was baked again at 65...
ABSTRACT As part of a multi-wavelength campaign to observe the 2000–2002 outburst of the prototypical symbiotic star Z Andromedae, we observed this object six times each with the Multi-Element Radio Linked Interferometer Network (MERLIN) and Very Large Array (VLA). The radio flux varied sign...

The selection of the wavelength of ultraviolet light and visible light has a profound impact on the recording and readout performance. We have studied experimentally the absorption spectra of some samples of typical doubly doped lithium niobate crystals, such as Mn:Fe...
Ultraviolet light with a primary wavelength of 254 nanometers (0.01 mil), referred to as UVC, is being used to kill microbes in the air and on the surfaces of coils/drain pans in HVAC systems and on the surfaces of food processing equipment. UVC also is being combined with catalytic ...
The photoelectrochemical (PEC) properties of ZnO nanostructures were investigated by using an ultraviolet lamp with a wavelength of 365 nm and a measured intensity of 0.4 mW/cm 2 2. Photocurrent densities of 0.61, 0.47, and 0.37 mA/cm 2 were obtained for nanowires, nanosheets, and nanorods, ...
