Interfacial Modulation of Lithium Deposition via an Adaptive Poly(Ether‐Thiourea) Protective Layer

open access: yesCarbon Energy, EarlyView.
An efficient adaptive protective layer based on thiourea H‐bonded supramolecular polymer is developed for lithium metal anodes. Physically, its viscoelastic properties promote a homogeneous Li+ flux, effectively preventing dendrite formation. Chemically, the polymer facilitates the formation of beneficial SEI components, such as Li₃N and Li₂O, greatly ...

Carbon‐Supported Dual‐Nickel Atom Catalysts With Stabilized Ni─N3 Active Sites for Efficient CO2 Electroreduction

open access: yesCarbon Energy, EarlyView.
Dual‐nickel atom catalysts (Ni‐DACs) are developed to stabilize unsaturated Ni─N3 atomic sites by constructing N3Ni─NiN3 dual‐atom structures from coal. Benefiting from the modulated electronic structure that optimizes intermediate adsorption, Ni‐DACs outperform Ni‐SACs in CO2 electroreduction, achieving a max FECO of 98.6% at −0.8 V vs RHE and a TOF ...

Methyl on the Bridge: 2‐Methyl Propellane as Precursor for 1,3‐Substituted 2‐Methylated Bicyclo[1.1.1]Pentanes

open access: yesChemistry – A European Journal, EarlyView.
The synthesis of 2‐methyl propellane and its conversion to various 1,2‐ and 1,2,3‐di‐ and trisubstituted bicyclopentanes is reported. Abstract Bicyclo[1.1.1]pentanes (BCPs) have emerged as isosteric replacements for mono‐ and para‐substituted benzene rings in medicinal and materials applications, involving substitution at the BCP bridgehead (1,3 ...

Hidden Markov graphical models with state‐dependent generalized hyperbolic distributions

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract In this article, we develop a novel hidden Markov graphical model to investigate time‐varying interconnectedness between different financial markets. To identify conditional correlation structures under varying market conditions and accommodate shape features embedded in financial time series, we rely upon the generalized hyperbolic family of ...
