Low‐Temperature in Situ Upgrading of Ultra‐Deep Heavy Oil Using Ni–Ce/MOF–OTf Superacid Catalysts to Enhance Energy Utilization and Sustainability

EcoEnergy, EarlyView.
A triflate‐functionalized Ni–Ce/MOF–OTf superacid enables low‐temperature (∼140°C) in situ upgrading of ultra‐deep heavy oil. It reduces viscosity by 92.11% in 12 h, maintains activity over cycles, and delivers 90.25% recovery with a lower carbon footprint by selective bond cleavage. ABSTRACT Ultra‐deep heavy oil is an important unconventional resource,

Crystal Orientation Regulation and Dynamic Protection via Dual Interface Engineering for Dendrite‐Free Zinc Deposition

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A dual‐interface engineering strategy is innovatively proposed to achieve dendrite‐free Zn anodes through crystallographic orientation regulation and adaptive interfacial protection. By pre‐coating eco‐friendly di‐pentaerythritol, horizontal growth of ZHS along the (001) plane is induced, which in turn guides epitaxial Zn deposition on the (002) plane.

Integrated Solvent‐Catalyst‐Dopant Strategy via Acidic DES for Synthesizing Lignin‐Derived Carbon Dots With High‐Quantum Yield to Achieve Efficient Photocatalytic Degradation of Tetracycline

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A deep eutectic solvent (ChCl/pTSA) platform enables integrated solvent, catalyst, and dopant functions, producing sulfur‐doped carbon quantum dots with a high sp2‐C content (82.8%) and a quantum yield of 56.9%. When combined with TiO2, the CQDs form TiOC and TiOS interfacial bridges, achieving 97.3% tetracycline photodegradation with excellent ...

A Short Total Synthesis of the Daucane Sesquiterpenoid Ferutinin

European Journal of Organic Chemistry, EarlyView.
Only nine steps were required to access the bioactive daucane sesquiterpene ester ferutinin (1) from 3‐methyl‐2‐cyclopentenone (3) and allyl p‐tolyl sulfoxide. A one‐pot 1,4‐addition/aldol sequence was used to rapidly provide diene 2 (TBS = tert‐butyldimethylsilyl), ring‐closing metathesis of which followed by alkylation and acylation gave rise to the ...

Thermally activated delayed fluorescence exciplex sensitizers with fast reverse intersystem crossing for improving efficiency stability of organic light‐emitting diodes based on multi‐resonance emitters

FlexMat, EarlyView.
Two exciplex emitters are constructed based on a host‐guest doping strategy, and their exciton dynamics processes are investigated in depth. High‐performance OLEDs are fabricated by employing these exciplexes as emitters or sensitizers, providing excellent electroluminescence efficiencies and low efficiency roll‐offs.

Heteroatom location‐ and orientation mode‐dependent reverse intersystem crossing rate in multiple resonance emitters

FlexMat, EarlyView.
By constructing two pairs of isomers with different heteroatom anchoring positions, the relationship between heteroatom location and orientation mode and reverse intersystem crossing rate constant (kRISC) in multiple resonance (MR) emitters is systematically investigated.
