This work is devoted to the study of magnetic properties and Electron Paramagnetic Resonance (EPR) spectroscopy TiO2:Fe nanoparticles doped with Al in different structural states. The sol-gel methods have been used obtain particles both crystalline (average size from 3 20 nm) X-ray amorphous electron paramagnetic resonance spectra samples aluminum besides a line g-factor ~2 exhibit small signal...
The application of sensitizers to utilize visible light for chemical reactions is an established method. Several recent publications have impressively demonstrated the versatile use of visible light for various transformations, such as the conversion of alcohols to alkyl halides, and [2+2], [3+2], and [4+2] cycloadditions as well as carbon– carbon and carbon–heteroatom bond formations. The comb...
