In situ electro-synthesis and resynthesis of redox actives in aqueous organic redox flow batteries
We report in situ continuous anthraquinone electrosyntheses from lower-cost anthracene feedstock in a flow cell reactor to lower mass production cost of anthraquinone-based electrolytes, and in situ electro-resyntheses of active molecules from decomposed species to extend lifetime of aqueous anthraquinone redox flow batteries.
Bis-Schiff base linkage makes gold nanoclusters brighter
We develop an efficient strategy to increase the photoluminescence quantum yield of water-soluble gold clusters at the single-cluster level via formation of bis-Schiff base linkages, and its mechanism is deeply investigated.
Nickel-catalyzed asymmetric hydrogenation of oximes
The asymmetric hydrogenation of oximes to chiral hydroxylamines is a long-standing problem due to the labile N-O bond and inert C=N bond. It has now been enabled by a chiral nickel catalyst with excellent results in which the weak interactions between catalyst and substrate play crucial roles.
Acidic CO2RR Employing Bimetallic Catalysts Increases the Carbon Utilization Efficiency in CO2 Electrolysis
With growing interest in the upgrade of CO2 to valuable chemicals, the present-day problem of low carbon utilization – the result of carbonate formation – is attracting ever-increasing attention. We develop a new electrocatalyst that works well in acid, improving the activity in CO2RR.
Protein changes on the ultrafast timescale
In phytochrome Agp2 ultrafast proton-transfer occurs from the chromophore to a hydrogen-bonded water network in the protein prior to photoisomerization. The altered hydrogen bonds persist after photoisomerization and trigger together with the new chromophore geometry the activated protein conformation.
"Concentriosome": A Compartment Without Permanent Boundaries
We have unearthed a new artificial organelle known as “Concentriosome” to carry out spatiotemporal enzymatic cascade reactions in solution and regiospecific chemical events using the standing waves that in turn are generated by the Faraday Instability setup.
High-resolution crystal structure of a 20 kDa superfluorinated gold nanocluster
The design, synthesis, and high-resolution single-crystal X-ray structure of a superfluorinated 20 kDa gold nanocluster was achieved. The nanocluster presents an Au25 core coated by a shell of multi-branched highly fluorinated thiols (SF27) resulting in almost 500 fluorine atoms.
