Effect of Precursor Structure on Pore Evolution of Pitch‐Derived Porous Carbon Nanoarchitectonics

Carbon and Hydrogen, EarlyView.
Precursor microstructure–regulated activation and pore evolution in pitch‐derived porous carbon, demonstrating the superior nanoarchitectonics at moderate mesophase content. ABSTRACT Developing high‐performance porous carbons (PCs) requires precise microstructural control, which can be effectively understood within the framework of nanoarchitectonics ...

Unlocking Enhanced Hydrogen Storage in Naphthalene via K‐Induced Acidity and Metal Dispersion in Dendritic Catalysts

Carbon and Hydrogen, EarlyView.
Dendritic micro‐mesoporous composite catalysts through K‐induced enhancement of acidity and metal dispersion were developed. ABSTRACT Novel dendritic ZSM‐22/DMSNs (ZD) micro‐mesoporous composites with center–radial pore structure and suitable acidity were developed by nano‐assembly strategy. Subsequently, Pt/ZD‐K catalysts were synthesized based on the

Predicting polycyclic aromatic hydrocarbon concentrations in soil and water samples [PDF]

, 2010
Polycyclic Aromatic Hydrocarbons (PAHs) are compounds found in the environment that can be harmful to humans. They are typically formed due to incomplete combustion and as such remain after burning coal, oil, petrol, diesel, wood, household waste and so ...

Insights Into the Effect of Humic Acids Extraction From Coal on Hard Carbon Microstructure and Sodium Storage Properties

Carbon Energy, EarlyView.
This study employs a simple solid‐phase alkali‐oxygen oxidation (SAO) method to extract inherent components (humic acids) from coal. We successfully extracted yellow, brown, and black humic acids by adjusting the amount of alkali. Among them, brown humic acid extraction created abundant ultra‐micropores and closed pores, greatly enhancing sodium ...

Benzo[cd]azulenyl: A Structural Isomer of Phenalenyl—Synthesis and Properties of Its Tri‐tert‐butyl‐substituted Derivative and Formation of a Thermal‐ and Photoresponsive σ‐Dimer

Chemistry – A European Journal, EarlyView.
Benzo[cd]azulenyl, a nonalternant isomer of phenalenyl, is identified as a new member of the nonalternant hydrocarbon radical family. The tri‐tert‐butyl substituted derivative forms a stable σ‐dimer in the solid state. Upon exposure to external stimuli such as light and heat, the σ‐bond of the dimer dissociates, producing the monomeric radical.

Interplay of Orbital Overlap and Exciton Coupling in the Optical Properties of Adamantylethynyl‐Substituted Pyrene Molecular Crystals

Chemistry – A European Journal, EarlyView.
Sterically shielded adamantylethynyl‐substituted pyrenes form quasi‐one‐dimensional π‐stacks that enable direct quantification of solution‐to‐crystal spectral shifts. The optical response is dominated by band dispersion arising from frontier crystal orbitals, while excitonic contributions are secondary.

Three‐Step Synthesis Toward Fluorene‐Based Non‐Fused‐Ring Acceptors for Organic Solar Cells

Chemistry – A European Journal, EarlyView.
Applying a simple three step synthesis strategy leads to two fluorene‐based non‐fused‐ring electron acceptors, FHM‐Cl and FHM‐F for organic solar cells. The chlorinated variant delivers markedly higher efficiency due to broader light harvesting and favorable molecular packing, resulting in improved charge transport and reduced recombination losses ...
