Enhancement Method and Safety Analysis of Sealing Unit in Gas Packer

Shiyou jixie
The gas packer rubber is a key part for achieving separate layer and interval production of gas wells. The conventional three-unit rubber barrel structure is prone to initial failure during setting, which will lead to a decrease in the overall stress ...

Infinite Functional Versatility, Formidable Limits: Evaluating Gallium‐Based Liquid Metals in Rechargeable Batteries

Carbon Energy, EarlyView.
Beyond the hype surrounding the self‐healing properties of gallium‐based liquid metals (Ga‐LMs), this perspective critically examines their functional roles in metal‐ion batteries, highlighting both their underlying merits and the often‐overlooked challenges, including non‐representative design and testing configurations, performance overestimations ...

π‐Extended Salphen Scaffolds Enable CO2 Electroreduction and Singlet Oxygen Generation

Chemistry – A European Journal, EarlyView.
New family of π‐extended salen ligands bearing phenylene bridge and tunable phenyl‐based substituents, and their corresponding boron difluoride complexes. Thanks to the extended π‐delocalization over the molecule, the ligands themselves show promising results in electrochemical CO2 reduction to CO, while the complexes act as efficient photosensitizers ...

New Insights into Poly(Dichlorophosphazene) Synthesis via Me3Si─N═PCl3 Polymerization: An Experimental and Theoretical Study

Chemistry – A European Journal, EarlyView.
Poly(dichlorophosphazene) synthesis via Me3Si─N═PCl3 polymerization was reinvestigated using quantum chemical calculations and experiments. A cationic initiator (Ph3PCl2) enables ambient‐temperature polymerization through chloride‐catalyzed cationic pathways involving dissociation, nucleophilic chloride attack, and chain‐propagating species formation ...
