Ferrate(VI) Oxidation of Thiourea

, 1999
The rates of thiourea oxidation with Fe(VI) were determined as a function of pH (8.8−11.5) and temperature (10−35 °C). The rate law for the oxidation of thiourea was found to be −d[Fe(VI)]/dt = k 0{[H+]/[H+]+K 9)}[Fe(VI)][thiourea] where k 0 = 5.9 × 104 ...

Efficient and Durable Sulfion Oxidation Coupled With Hydrogen Production via Cu@Cu2S Heterostructured Nanowires

Carbon Energy, EarlyView.
We present a facile and liquid‐phase approach to synthesize Cu@Cu2S core‐shell heterostructure nanowires derived from copper nanowires at room temperature for robust sulfide oxidation reaction (SOR)‐assisted H2 generation. The Cu@Cu2S core‐shell heterostructure nanowires exhibit superior SOR activity with an ultralow potential of 0.3 V (vs.

An Electrophilic Uridine Building Block for Post‐Synthetic RNA Modification as Exemplified for Spin Labeling

Chemistry – A European Journal, EarlyView.
An electrophilic 5‐isothiocyanatomethyl uridine building block enables modular post‐synthetic RNA labeling with primary amine‐containing probes. Positioning the functionality in the major groove minimizes structural perturbation and allows facile conjugation of sensitive tags such as TEMPO spin labels for paramagnetic relaxation enhancement studies ...
