Dispersion‐Clamped Crystalline Supramolecular Columnar π‐Stacks of Adamantyl‐Substituted Pyrenes

Angewandte Chemie, EarlyView.
Can neutral hydrocarbon π‐systems be forced into perfectly aligned cofacial stacks in crystals? An adamantyl‐decorated pyrene derivative crystallizes into rare translationally zero‐offset π‐columns, producing a short π–π distance below 3.3 Å and a large color shift arising from frontier crystal orbital (FCO) formation.

Investigation of the Amount and Possible Source of Polycyclic Aromatic Hydrocarbons (PAHs) in the Dust Deposited on the Leaves of Trees in Ahvaz

علوم آب و خاک, 2021
Dust deposited on the leaves of trees can be effectively used as the monitors of polycyclic aromatic hydrocarbons (PAHs). The dust deposited on the leaves can be used as an appropriate index for evaluating PAHs in the atmosphere.

Liquid Gallium Nanozyme Coatings Enable Sustained Nitric Oxide Generation With Antioxidant and Anti‐Inflammatory Functions

Advanced Science, EarlyView.
Liquid gallium (Ga) acts as a catalytic center for nitric oxide (NO) generation within a tannic acid–zirconium metal–phenolic network coating. Stabilized Ga nanoparticles catalyze S‐nitrosothiol decomposition through surface electron transfer, enabling controlled NO production, enhancing endothelial biocompatibility, and providing antioxidant and anti ...

Diversity‐Oriented Two‐Step Annulative π‐Extension Enables Access to Structurally Complex Nanographenes

Angewandte Chemie, EarlyView.
Pd‐catalyzed C–H arylation of polycyclic aromatic hydrocarbons (PAHs) with various aryltrimethylsilanes enables the preparation of structurally complicated arylated PAHs, which can be further transformed to nanographenes in a manner of two‐step annulative π‐extension (APEX) reaction.

Dual‐Targeting Biomimetic Nanozymes Loaded Microneedle Patch Promotes Scarless Wound Healing Through Anti‐Inflammatory and Anti‐Fibrotic Effects

Advanced Science, EarlyView.
This study developed a dual‐targeting biomimetic nanozyme hybrid system (Cu‐CeO2@ABs‐FTP) and integrated it with HAMA hydrogel to fabricate a microneedle patch (CAF@MN). The patch promotes fibroblast‐mediated wound repair, targets macrophages to induce M2 polarization, and targets myofibroblasts to exert anti‐fibrotic effects, thereby enabling rapid ...
