Embedded Direct Ink Writing of Thermoset and Elastomeric Polymers via Frontal Polymerization

Advanced Functional Materials, EarlyView.
Embedded frontal polymerization direct ink writing (FP‐DIW) combines frontal ring‐opening metathesis polymerization with embedded 3D printing to decouple deposition from curing. A yield‐stress support bath stabilizes low‐viscosity inks, while on‐demand thermal initiation enables controlled front propagation. This approach expands the accessible feature

Self‐Assembled Hybrid Cell‐Enzyme Materials for Gas‐Powered Biocatalysis

Advanced Functional Materials, EarlyView.
Integrating living cells with programmable enzyme networks enables hybrid materials that convert gaseous feedstocks into chemical reducing power. These gas‐powered catalytic beads operate as modular, recyclable platforms for adaptive biocatalysis and sustainable synthesis.

Designing Vanadium‐Based Oxide Electrocatalysts for Water Splitting: Experimental and Mechanistic Insights with Machine Learning

Advanced Functional Materials, EarlyView.
This review establishes structure‐property‐mechanism relationships across six modification strategies for V‐based oxide water‐splitting electrocatalysts: lattice engineering, heteroatom doping, interface engineering, carbon‐based hybridization, morphology engineering, and surface reconstruction and pre‐catalyst design, where dissolution is reframed as ...

On-Surface Cross-Coupling Reactions

The Journal of Physical Chemistry Letters, 2023
On-surface synthesis, as a bottom-up synthetic method, has been proven to be a powerful tool for atomically precise fabrication of low-dimensional carbon nanomaterials over the past 15 years. This method relies on covalent coupling reactions that occur on solid substrates such as metal or metal oxide surfaces under ultra-high-vacuum conditions, and the

Cross-Coupling Reactions of Nitroarenes

Accounts of Chemical Research, 2021
Cross-coupling reactions are powerful synthetic tools to construct diverse chemical bonds often found in, for example, advanced materials and pharmaceuticals. Since their discovery, haloarenes have habitually been used as electrophilic coupling partners both in academic and industrial contexts.

Iron-Catalyzed Cross-Coupling Reactions

Journal of the American Chemical Society, 2002
Simple iron salts such as FeCl(n), Fe(acac)(n) (n = 2,3) or the salen complex 4 turned out to be highly efficient, cheap, toxicologically benign, and environmentally friendly precatalysts for a host of cross-coupling reactions of alkyl or aryl Grignard reagents, zincates, or organomanganese species with aryl and heteroaryl chlorides, triflates, and ...

First Cross-Coupling Reactions on Tetrazines

Organic Letters, 2003
[reaction: see text] A series of substituted chlorotetrazines were reacted with different terminal alkynes under Sonogashira or Negishi coupling conditions to furnish alkynyl-tetrazines in good to moderate yield. The electron-donating properties of the substituent on the tetrazine core were found to have a significant influence on the success of the ...

Cobalt-catalyzed cross-coupling reactions

Chemical Communications, 2008
In the last few years, we and other groups have demonstrated that economical cobalt salts can advantageously replace expensive and toxic catalysts for cross coupling reactions. These cobalt-catalyzed reactions have considerably extended the range of functionalized compounds.
