The surface wettability of catalysts is typically controlled via surface treatments that promote catalytic performance. Here we report on potential-regulated hydrophobicity/hydrophilicity at cobalt-based oxide interfaces with an alkaline so...
Gold-catalysed asymmetric net addition of unactivated propargylic C-H bonds to tethered aldehydes [0.03%]

The asymmetric one-step net addition of unactivated propargylic C-H bond to aldehyde leads to an atom-economic construction of versatile chiral propargylic alcohols but has not been realized previously. Here we show its implementation in an...
DYW domain structures imply an unusual regulation principle in plant organellar RNA editing catalysis [0.03%]
DYW结构域结构暗示植物器官ellerRNA编辑催化中的异常调控原则
Mizuki Takenaka,Sachi Takenaka,Tatjana Barthel et al.
Mizuki Takenaka et al.
RNA editosomes selectively deaminate cytidines to uridines in plant organellar transcripts-mostly to restore protein functionality and consequently facilitate mitochondrial and chloroplast function. The RNA editosomal pentatricopeptide repe...
Reversible H2 Oxidation and Evolution by Hydrogenase Embedded in a Redox Polymer Film [0.03%]
嵌入在导电聚合物膜中的氢酶可逆地催化析氢和氧化反应

Steffen Hardt et al.
Efficient electrocatalytic energy conversion requires the devices to function reversibly, i.e. deliver a significant current at minimal overpotential. Redox-active films can effectively embed and stabilise molecular electrocatalysts, but me...
19F- and 18F-Arene Deoxyfluorination via Organic Photoredox-Catalysed Polarity-Reversed Nucleophilic Aromatic Substitution [0.03%]
通过有机光氧化还原催化反向亲核芳香取代实现芳环的19F和18F烷氧基氟化反应
Nicholas E S Tay,Wei Chen,Alison Levens et al.
Nicholas E S Tay et al.
Nucleophilic aromatic substitution (SNAr) is routinely used to install 19F- and 18F- in aromatic molecules, but is typically limited to electron-deficient arenes due to kinetic barriers associated with C-F bond formation. Here we demonstrat...
Practical Synthesis of C-1 Deuterated Aldehydes Enabled by NHC Catalysis [0.03%]
