ÜberN-Oxy-carbostyril-carbonsäure

Carbostyril derivatives as antenna molecules for luminescent lanthanide chelates.

Luminescent lanthanide complexes consisting of a lanthanide-binding chelate and organic-based antenna molecule have unusual emission properties, including millisecond excited state lifetimes and sharply spiked spectra, compared to standard organic fluorophores. We have previously used carbostyril (cs124, 7-amino-4-methyl-2(1H)-quinolinone) as an antenna molecule (Li and Selvin, J. Am. Chem. Soc...

Low-energy Cathodoluminescence for (Oxy)Nitride Phosphors

Nitride and oxynitride (Sialon) phosphors are good candidates for the ultraviolet and visible emission applications. High performance, good stability and flexibility of their emission properties can be achieved by controlling their composition and dopants. However, a lot of work is still required to improve their properties and to reduce the production cost. A possible approach is to correlate ...

2-[(tert-But­oxy­carbonyl­amino)­oxy]acetic acid

The title compound, C(7)H(13)NO(5), was prepared by the condensation of O-(carb-oxy-meth-yl)hydroxyl-amine and (Boc)(2)O (Boc = but-oxy-carbon-yl).In the crystal, mol-ecules are linked by weak inter-molecular N-H⋯O hydrogen bonds.

Understanding Corrosion Mechanisms in Oxy-Fired Systems

Replacing air with oxygen in coal-fired boilers (i.e. oxy-firing) combined with flue gas recirculation is a leading strategy to concentrate CO2 and assist in carbon capture and sequestration. A significant area of concern is the fireside corrosion with oxy-firing due to the higher CO2 levels in the combustion gas and potentially higher SOx and H2O levels. In order to investigate this complicate...
