Abstract. We perform an inverse modelling analysis to quantify biomass burning emissions of carbon monoxide (CO) from the extreme wildfires in Canada between May and September 2023. Using GEOS-Chem model, we assimilated observations Tropospheric Monitoring Instrument (TROPOMI) separately then jointly with Total Carbon Column Observing Network (TCCON) measurements. also evaluated prior Quick Fire Emissions Dataset (QFED), Blended Global Biomass Burning Product eXtended (GBBEPx), Assimilation...
β-Dihydronicotinamide adenine dinucleotide (NADH) plays a critical role in biological redox processes. Inside the cell, NADH can be folded or an unfolded conformation, depending on chemical environment that surrounds it. It is known selective excitation of induce energy transfer events from this nucleotide to reduced nicotinamide chromophore. From anticipated time scales, process must compete with adenine's internal conversion channel, which occur sub-picosecond scale. In work, we studied...
We have designed and synthesized two new cyaninic Nd3+ complexes where the lanthanide emission can be induced from simultaneous two-photon absorption followed by energy migration. These correspond to a molecular design that uses an antenna ligand formed functionalization of heptamethine dye with 5-ol-phenanthroline or 4-phenyl-terpyridine derivatives. employ important nonlinear optical properties symmetric polymethines sensitize ion. verified biphotonic excitation indirectly induces 4F3/2 →...
Nicotinamide adenine dinucleotide (NADH) is an important enzyme cofactor with emissive properties that allow it to be used in fluorescence microscopies study cell metabolism. Its oxidized form NAD+, on the other hand, considered produce negligible fluorescence. In this contribution, we describe photophysics of isolated nicotinamidic system both its reduced and states. This was achieved through model molecules do not carry nucleotide since absorbance would overlap absorption spectrum...
