The effects of visible and UV light on the characteristics and properties of Prudhoe Bay (PB) and South Louisiana (SL) emulsions were investigated to better understand the role of sunlight on the fate of spilled crude oils that form emulsions with a dispersant in the aquatic environment. ...
VisibleandultravioletlightA series of TiO2 photocatalysts were obtained using several calcination temperatures ranging from 350 to 750 °C. The photocatalysts' characteristics by X-ray diffraction, UV–vis and FTIR diffuse reflectance spectroscopies, X-ray photoelectron spectroscopy, BET and BJH methods...

5) absorptivity of ultraviolet and visible light 紫外-可见光吸收性能 例句>> 6) UV-visible-infrared 紫外-可见光-红外补充资料:紫外分光学 分子式:CAS号:性质:利用紫外分光光度计进行研究的学科。其测定原理是当物质受到紫外光照射时,出现光吸收。根据分子中不同的键合情况,在不同波长处出现不同强度的光...
the M1and M3dyes are formed, the polarizing ability of which in uniaxially oriented polyvinyl-alcohol films is higher than in the M2dye produced as a result of diazo coupling into the α position relative to the amino group. On irradiation by UV light, the dyes are subjected to photodestruct...
If the visible light spectrum passes through a prism, the resulting rainbow reveals all the colors in the spectrum. These range from red, with a wavelength of 700 nanometers (which is incredibly small), through orange, yellow, green, blue and finally violet, with a wavelength of 380 nanomet...
TiO2 photocatalyst were obtained from the hydrolysis product of TiOSO4 with ammonia and the photocatalytic activities were investigated by the photocatalytic degradation of methyl orange aqueous solution under UV-light and visible-light. The results showed that the absorption intensity in visible-light was...
These compounds absorb light in near-UV and visible spectral regions, which also influences atmospheric photochemical processes and leads to the formation of secondary organic aerosol (SOA)2,3. The light absorption property of OA depends on its complex chemical composition, which also depends on ...
Two 1,2-diketones, 1-phenyl-1,2-propanedione (PD) and 2,3-butanedione (BD) were investigated as new visible light photosensitizers for formulating a dental resin composite of bis-GMA in order to improve the physical properties of the resin composite. The results were then compared with thos...
