Homomolecular non-coherent photon upconversion by triplet-triplet annihilation using a zinc porphyrin on wide bandgap semiconductors
Abstract Non-coherent upconversion, realized by homomolecular triplet–triplet annihilation of a zinc metalloporphyrin absorber, has been measured for the metalloporphyrin adsorbed on metal oxideExpand
Spectroscopic and Structural Studies of a Surface Active Porphyrin in Solution and in Langmuir-Blodgett Films.
TLDR
The Langmuir-Blodgett (LB) technique is a facile means of preparing ordered assemblies in thin films to study distance-dependent energy transfer processes in S-E systems and was used in this report to control the aggregation of a functionalized ZnTPP on solid substrates, suggesting that NCPU from Zn TPP as a dual S- E required not just a controlled aggregation but a specific orientation of the molecules with respect to each other.

Cation binding properties of an anionic gemini surfactant monolayer
Abstract A new class of anionic, gemini surfactants based on N,N’-dialkyl-N-N’-diacetate ethylenediamine has recently been reported in the literature, with the compounds exhibiting controllable and,Expand
Photophysics and halide quenching of a cationic metalloporphyrin in water.
TLDR
The results presented here highlight the notion that significant iodide quenching of the ZnTMPyP S1 state can be a source of inefficiencies in porphyrin-based dye-sensitized solar cells and indicate that no significant loss of efficiency will be introduced by using iodide as component of the electrolyte system in upconversion by triplet-triplet annihilation (UC-TTA) enhanced solar cells.

Spectroscopic Studies of Synthetic and Natural Saponites: A Review
Saponite is a trioctahedral 2:1 smectite with the ideal composition MxMg3AlxSi4xO10(OH,F)2.nH2O (M = interlayer cation). Both the success of the saponite synthesis and the determination of itsExpand
Bioconjugated nanomaterials on devices for infectious disease diagnostics.
TLDR
This review presents the most common and most promising functional groups, bioconjugation schemes and patterning strategies of nanomaterials on sensing devices and their specific application to infectious pathogen detection. Expand
Urea-Assisted Synthesis and Characterization of Saponite with Different Octahedral (Mg, Zn, Ni, Co) and Tetrahedral Metals (Al, Ga, B), a Review
TLDR
Urea, a compound figuring in many prebiotic model reactions, circumvents the formation of undesirable brucite, Mg(OH)2, in the final product, by slowly releasing ammonia thereby controlling the hydrolysis of magnesium. Expand
Urea-Assisted Synthesis and Characterization of Saponite with Different Octahedral (Mg, Zn, Ni, Co) and Tetrahedral Metals (Al, Ga, B), A Review
Clay minerals surfaces potentially played a role in prebiotic synthesis through adsorption of organic monomers that give rise to highly concentrated systems; facilitate condensation andExpand
