Carbon Dot Self‐Assembly: Bottom‐Up Fabrication, Morphological Evolution, Luminescence Regulation, and Advanced Applications

open access: yesAggregate, Volume 7, Issue 5, May 2026.
The self‐assembly of carbon dots, which enables precise control over their macroscopic architectures and collective properties, profoundly enhances their functionality. This review systematically summarizes the field through four key aspects—morphology control, luminescence modulation, assembly mechanisms, and advanced applications—and thereby offers a

Thickness Reduction Strategy for Graphite Composite Bipolar Plates: Materials, Structure, and Manufacturing Process

open access: yesCarbon Neutralization, Volume 5, Issue 3, May 2026.
Schematic diagram of challenges and advanced strategies by CBP after thickness reduction. ABSTRACT The proton exchange membrane fuel cell (PEMFC) converts clean hydrogen's chemical energy into electricity and is vital for carbon neutrality. However, its development is limited by low volumetric power density and high cost.

Wafer‐Scale Self‐Limiting Epitaxy of Bernal‐Stacked Single‐Crystal Boron Nitride

open access: yesSmall, Volume 22, Issue 26, 8 May 2026.
Wafer‐scale, single‐crystal Bernal‐stacked boron nitride (bBN) bilayers are grown by flow‐modulated MOCVD, where monoatomic Ni step edges on Ni(111) deterministically direct AB stacking. As an ultrathin interlayer, bBN suppresses interfacial scattering and enables robust, nonvolatile polarization switching in MoS2 channels, offering a scalable platform

Controlled Formation of Carbon Nanotubes and Nanotube Junctions from Bilayer Graphene

open access: yesSmall, Volume 22, Issue 26, 8 May 2026.
Twisted bilayer graphene is cut using a scanning transmission electron microscope to create individual chiral carbon nanotubes and interconnected nanotube junctions. The sculpting is facilitated by in situ heating and automated beam control. Bilayer graphene ribbons with a width of less than approximately 4 nm spontaneously convert to CNTs, while no ...

First Access to Tetraazadiindenopyrenes via Selective Pyrrole Cyclization of Phenyl‐Substituted Tetraazapyrene Derivatives on Au(111)

open access: yesSmall Science, Volume 6, Issue 5, May 2026.
Contrary to long‐held expectations of on‐surface chemistry, tetraphenyl‐substituted tetraazapyrene undergoes selective pyrrole cyclization and C–C coupling on Au(111), forming a distinctive N‐doped nanographene consisting of fused tetraazadiindenopyrene and phenanthrene cores with embedded pyridinic and graphitic nitrogen.
