Hypergolic Copper Cluster‐Based Covalent Organic Frameworks

Advanced Science, EarlyView.
Hpergolic cluster‐based covalent organic framework (Cu3‐CB‐COF), assembled from aldehyde‐functionalized carborane monomers and trinuclear copper clusters, demonstrates a strong synergy between its catalytic copper nodes and energetic carborane backbones.

Interfacial Growth of 420 nm Ultrathin and Dense MOFs for Composite Electrolyte to Reduce Li+ Conduction Resistance and Inhibit Lithium Dendrite

Advanced Science, EarlyView.
In this work, an interfacial growth method using PVDF‐HFP enables controlled permeation of 2‐methylimidazole to react with Co2+, forming an ultrathin (420 nm) ZIF‐67 layer by precisely tuning the reaction time. This dense layer promotes lithium salt dissociation and suppresses dendrite growth, while its ultrathin nature reduces Li+ transport resistance,

Oxygen‐Assisted MOCVD Growth of Monolayer PtSe2 Films With Bandgap Opening for Semiconducting FET Channels

Advanced Science, EarlyView.
Monolayer PtSe2 films are successfully grown via optimized MOCVD, achieving uniform coverage over a 1.5 cm × 1.5 cm area. Oxygen‐assisted growth effectively removes carbon impurities, ensuring high film quality. Array‐level FETs based on monolayer PtSe2 channels demonstrate low off‐current and high ION/IOFF ratios, highlighting the potential of PtSe2 ...
