Energy Transfer‐Mediated Magnetoluminescence of an Octahedral MnII Complex Ligated With Bis(Diphenylphosphino)Methane Dioxide

Angewandte Chemie, EarlyView.
Energy‐transfer‐mediated magnetoluminescence of paramagnetic transition metal complexes: dope solids of an octahedral MnII complex into the corresponding ZnII complex exhibited a pronounced magnetic field response of emission spectra under the application of magnetic fields.

Structure and Function of a Multi‐Megadalton Virus‐Like Proteolytic Dodecahedron

Angewandte Chemie, EarlyView.
Zuzalysin, a virulence metallopeptidase of the periodontal pathogen Porphyromonas gingivalis, is secreted as a latent, flexible ≈95‐kDa monomer. Calcium triggers cysteine‐switch activation and hierarchical assembly into pentamers, bipentamers, tripentamers, and a ≈5.6‐MDa, ≈355‐Å dodecahedron. Structures at 1.8–3.6 Å reveal a virus‐sized catalytic cage

Site‐Specific Molecular Engineering Redirects Radical Pathways for Selective Photocatalytic Coupling of Methane to C2+ Hydrocarbons

Angewandte Chemie, EarlyView.
Site‐specific self‐assembly of alkyl thiols on Au/TiO2 enables precise modulation of interfacial electron distribution and the local microenvironment through covalent Au‐thiolate interactions. This site‐specific molecular engineering synergistically promotes surface kinetics and charge separation, suppressing ·O2−‐driven overoxidation and thereby ...

Novel Catalysts for Low-temperature Co-methanation of CO and CO2 in Coke Oven Gas

, 2014
焦炉气是在炼焦过程中产生的副产品，主要成分是氢气和甲烷，还有一氧化碳、二氧化碳、烯烃等。每年中国焦炉气的产量约1200亿Nm3，其利用率约为55%，焦炉气通过甲烷化反应，将焦炉气中CO、CO2转化为甲烷，再通过变压吸附生产天然气具有较好经济价值和社会意义。甲烷化是强放热反应，反应器局部温升可以造成碳烃裂解而结碳，还可能容易使甲烷化催化剂烧结而失活。针对焦炉气甲烷化的工艺特点，本研究主要开发适于焦炉气中低温甲烷化催化剂。 本研究对于富氢焦炉气的甲烷化过程进行系统的分析和研究 ...

1,2‐Bis(boronate) Arenes by Borylation Directed Borylation

Angewandte Chemie, EarlyView.
Boron electrophiles derived from tetrabromo‐pyrazaboles and AlCl3 affect the regioselective vicinal double C–H borylation of a range of arenes and polycyclic aromatic hydrocarbons (PAHs). A subsequent pinacol installation step then affords the vicinal bis‐boronate ester‐substituted arene/PAH.
