Atomic force microscopic study of nanoscale interaction between N719 dye and CdSe quantum dot in hybrid solar cells and their enhanced open circuit potential

Remarkably selective biocompatible turn-on fluorescent probe for detection of Fe3+ in human blood samples and cells

“…Highly optically active metal chalcogenide/quantum dots (QDs) have been reported as fluorescence based sensors/receptors with excellent stability and photophysical properties. 6 Due to their tunable optical properties 6 a ,7 they have gained importance in numerous fields such as photovoltaics, 8 bioimaging 9 and as sensors 10,11 . In the early years Jiang et al reported a gallic acid modified nanometer sized alumina micro-column separations and were able to detect up to 52.1 μM Fe 3+ in real water samples using ICP-MS. 12 With time, in 2019 Mohammadi et al developed a MBTBA-Fe 3 O 4 @SiO 2 nanocomposite fluorescent ligand capable of sensing Fe 3+ with a detection limit of 43.09 nM.…”

Photo-active float for field water disinfection

“…TiO 2 absorbs ultraviolet light preventing its practical efficiency for solar applications. [14][15][16] However, recently several modifications have been made to extend the light absorption capability of TiO 2 into the visible light region by coupling with a narrow band gap semiconductor, 17,18 doping with transition metals (Fe, Co, Ag, Cr and Mo), 19 codoping with two or more foreign ions, surface sensitization by organic dyes or metal complexes, surface fluorination, addition of a sacrificial agent (SA), different preparation techniques 20 and noble metal deposition which induces a substantial influence in modifying the electronic band structure and construction of favorable surface structure resulting in higher visible light absorption. 19,[21][22][23][24] Introduction of anionic dopants, especially nitrogen, to TiO 2 makes it possible to achieve band gap narrowing.…”
