چکیده
A cursory look to the literature shows that only about 1% of the published papers classed as organic syntheses by Chemical Abstracts involve a photochemical step. On the other hand, in photochemistry courses it is often stated that excitation by light multiplies by 3 the accessible reaction paths, because the chemistry of the excited singlet and triplet states are added to that of the ground state. It thus appears that photochemical reactions are less used as they may be. As it has been again recently remarked, this limited diffusion may be due to ill-founded prejudices [1]. Two conditions should be verified in order that the potential of photochemical reactions is more extensively exploited. These are:

Effects of photochemical air pollution on the human eye--concerning eye irritation, tear lysozyme and tear pH.
This paper is presented to make both ocular symptoms and signs clear, by means of some experiments on the eye affected by photochemical air pollution. This paper summarizes three experiments, these results and discussion. The first series of experiments were performed in order to research eye irritation caused by photochemical synthetic irritants. They proved the threshold of eye irritation and...
متن کاملUsing Temperature of IR Sources for Assessing Photochemical and Aphakic Retinal Hazard
Introduction Blue light is a part of the spectrum with the highest energy content, which can reach the retina. The damage that it can cause to the retina is called photochemical or blue-light retinal injury. For the retinal injury assessment of the photochemical and aphakic retinal hazards in the wavelength range of 300-700 nm, use of effective spectral radiance limits (W.m-2.sr-1) seems to be ...
متن کاملPhotochemical degradation of azure-b with sulphate radical ion generated by peroxydisulphate ion with cupric ion
In this paper, the photochemical degradation of azure-b by Cu2+/S2O82− process has beenpresented. Cu2+ as photocatalyst and S2O82− ion as photooxidant used in this process. Atextremely low concentrations, cupric ion showed true catalytic activity in the overall process.The influence of various parameters on the performance of the treatment process has beenconsidered, such as pH, concentration o...
متن کاملQuasipermanent photochemical gratings in a dual use photorefractive polymer composite
The dual nature of ~3-~2-~4-~N,N-diethylamino!phenyl!ethenyl!-5,5-dimethyl-1,2-cyclohexenylidene!propanedinitrile ~Lemke-e! allows us to write both quasipermanent and erasable holographic gratings in the same storage volume. In the presence of a triplet excited sensitizer, Lemke-e undergoes a photochemical reaction allowing the creation of quasipermanent photochemical holographic gratings. In a...
متن کاملEnhancing the Photocatalytic Activity of Nano Nd-TiO2@SiO2 by coupled systems
Metal doped TiO2 catalysts were synthesized by sol-gel method and their activities were determined for degradation of methyl orang as a pollutant. Nd-doped TiO2 showed the maximum activity comparing with others. Colloidal SiO2 was used as a support to increase the surface area and also the activity. Nano-TiO2/SiO2/Nd was synthesized by sol-gel method and it was characterized using XRD, XRF, SEM...
