N-coordinated bimetallic defect-rich nanocarbons as highly efficient electrocatalysts in advanced energy conversion applications
Ulf Anders Hagfeldt, Sining Yun
Defect engineering in heterostructured carbon-based electrode materials has evolved as an emerging strategy to boost the electrocatalytic activity. Herein, a facile single-step route is reported to synthesize novel N-coordinated bimetal doped graphitic car ...
ELSEVIER SCIENCE SA2022Scaffolding protein functional sites using deep learning
Bruno Emanuel Ferreira De Sousa Correia, Karla Montserrat Castro Gilabert, Basile Isidore Martin Wicky, Jue Wang
The binding and catalytic functions of proteins are generally mediated by a small number of functional residues held in place by the overall protein structure. Here, we describe deep learning approaches for scaffolding such functional sites without needing ...
AMER ASSOC ADVANCEMENT SCIENCE2022Bioengineering a glucose oxidase nanosensor for near-infrared continuous glucose monitoring
Ardemis Anoush Boghossian, Hanxuan Wang, Vitalijs Zubkovs
Single-walled carbon nanotubes (SWCNTs) emit photostable near-infrared fluorescence that is conducive for optical glucose monitoring. Such SWCNT-based optical sensors often require the immobilization of proteins that can confer glucose selectivity and reac ...
2022Asymmetric azide-alkyne Huisgen cycloaddition on chiral metal surfaces
Harald Brune, Roland Hany, Roland Widmer, Michael Bauer, Samuel Thomas Stolz
Achieving fundamental understanding of enantioselective heterogeneous synthesis is marred by the permanent presence of multitudinous arrangements of catalytically active sites in real catalysts. In this study, we address this issue by using structurally co ...
NATURE RESEARCH2021Construction of Functional Superhydrophobic Biochars as Hydrogen Transfer Catalysts for Dehydrogenation of N-Heterocycles
To endow metal-free materials with the high catalytic activity that is typically featured by a metal-based catalyst is yet a constant pursuit in the field of catalytic chemistry. In this work, novel functional biochars (DCNs) were prepared from wheat straw ...
AMER CHEMICAL SOC2021Porous silicon-A versatile platform for mass-production of ultrasensitive SERS-active substrates
Surface-enhanced Raman scattering (SERS) spectroscopy is one of the most prospective methods combining state-of-the-art nanomaterials and optical techniques for highly sensitive express-analysis and detection of organic and bioorganic objects in liquids an ...
ELSEVIER2021Catalytic (3+2) annulation of donor-acceptor aminocyclopropane monoesters and indoles
Jérôme Waser, Emma Gabrielle Louise Robert, Vincent Géry C Pirenne
The efficient catalytic activation of donor-acceptor aminocyclopropanes lacking the commonly used diester acceptor is reported here in a (3 + 2) dearomative annulation with indoles. Bench-stable tosyl-protected aminocyclopropyl esters were converted into c ...
2021Alternative dimerization is required for activity and inhibition of the HEPN ribonuclease RnlA
The rnlAB toxin-antitoxin operon from Escherichia co/ifunctions as an anti-phage defense system. RnlA was identified as a member of the HEPN (Higher Eukaryotes and Prokaryotes Nucleotide-binding domain) superfamily of ribonucleases. The activity of the tox ...
OXFORD UNIV PRESS2021Cu/Metal Oxide Hybrid Nanocrystals as Electrocatalysts for the CO2 Reduction Reaction
The electrochemical CO2 reduction reaction (CO2RR) is envisioned to play a significant role in achieving carbon neutrality while contributing to storing renewable energies. Cu-based materials are among the most promising electrocatalysts. However, 16 diffe ...
EPFL2021Structures of ABCG2 under turnover conditions reveal a key step in the drug transport mechanism
Henning Paul-Julius Stahlberg, Dongchun Ni
ABCG2 is a multidrug transporter that affects drug pharmacokinetics and contributes to multidrug resistance of cancer cells. In previously reported structures, the reaction cycle was halted by the absence of substrates or ATP, mutation of catalytic residue ...
