Highly efficient and chemoselective singlet oxygen oxidation of unprotected methionine was performed in water using a continuous mesofluidic reactor. Sustainable process engineering conditions were combined to maximize efficiency atom economy, with virtually no waste generation safe operating conditions. Three water-soluble metal-free photosensitizers [Rose Bengal, Methylene Blue, tetrakis(4-carboxyphenyl)porphyrin] assessed. The best results obtained Rose Bengal (0.1 mol %) at room...
Abstract Continuous flow photochemistry relying on photosensitizers faces two main challenges: 1) Photodegradation (bleaching) and 2) the downstream removal of photosensitizer. Rose bengal (RB) is a common photosensitizer utilized for photooxygenation reactions with singlet oxygen ( 1 O 2 ), but notoriously sensitive to photobleaching difficult remove from reactor effluents. The heterogenization mesoporous silica nanoparticles (MSNs) arguably viable option such applications. Herein, we...
The plasmonic features of gold nanomaterials provide intriguing optical effects which can find potential applications in various fields. These depend strongly on the size and shape metal nanostructures. For instance, Au bipyramids (AuBPs) exhibit intense well-defined plasmon resonance, easily tunable by controlling their aspect ratio, act synergistically with chromophores for enhancing photophysical properties. In Rose Bengal-nanoparticle systems it is now well established that control...
This contribution focuses on modifying the composition and surface characteristics of powder metallurgy titanium substrates to improve their wear resistance reduce Young's modulus, while maintaining corrosion biocompatibility. The modification consists Mo TiN coatings produced by colloidal techniques which are deposited electrophoretic deposition (EPD) or spraying onto green sintered substrates. final structures formed during a heat treatment, diffusion consolidation layers take place....
CdSe thin films were deposited on glass substrates by a chemical bath deposition (CBD) in the system cadmium nitrite tetrahydrate (Cd(NO 3 ) 2 .4H O)-selenourea [SeC(NH ]-glycine-pH buffer of borate. According to processing conditions established L9 Taguchi experimental design, nine different films obtained. nanostructured with particle sizes range 100-200 nm show band gap values upper than 1.23 eV (CdSe theoretical gap) and main photoluminescence emission peak is 600 800 nm. CBD-CdSe...
In this work the stability of TiN and TiC nanopowders in isopropyl alcohol as well fabrication dense adhered thin coatings based on by electrophoretic deposition (EPD) have been evaluated terms zeta potential mass deposited when hydrazine is added. The surface nanoparticles has modified to improve dispersion adding a cationic polymer (polyethylenimine) dispersant with two different molecular weights. influence acidic/basic character solvent also order reach most efficient EPD process. It was...
Electrophoretic deposition (EPD) is a colloidal processing method which consists in the electrically driven movement and of charged particles onto conductive substrate. Understanding behavior nanoparticles therefore mandatory to prepare stable disperse suspensions suitable for EPD. Moreover, up today most proposed models EPD kinetics have been formulated considering electrophoresis process. However, effect other parameters than over kinetics, feature or coating morphology, has mainly...
CdSe thin films were prepared by a chemical bath deposition on glass substrates during the growing process at 70◦C.Nine different films obtained depending of conditions growing. The optical characterization shown bandgap upper than 1.74 reported for ambient temperature. This is common in luminescent materials due to size nanoparticles. In our case, we found nanorods sizes range 10 nm 60 conditions. We observed fotoluminescent peaks near 600 and 800 nm, indicating that this film good infrared...
