Engineering Biochar‐Derived Functional Materials for High‐Performance Supercapacitors: Design Principles, Mechanisms, and Scalable Strategies

Carbon Energy, EarlyView.
ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.

Palladium-Catalyzed Oxalyl Amide-Directed γ‑Arylation of Aliphatic Amines

, 2015
A method for palladium-catalyzed oxalyl amide-directed arylation of α-unsubstituted aliphatic amines with aryl iodides has been developed. A wide variety of aryl iodides are tolerated in this transformation, affording various γ-arylpropylamine ...

Multifunctional Design of Solid Polymer Electrolytes: Paving the Way for High‐Performance All‐Solid‐State Batteries

Carbon Energy, EarlyView.
This review provides a comprehensive and systematic overview of the multifunctional design strategies for solid polymer electrolytes (SPEs), a pivotal component for enabling high‐performance all‐solid‐state batteries (ASSBs). It begins with a detailed classification of SPE systems and elaborates on their respective molecular design principles. The work

Interaction between pheophorbide a and primary aliphatic amines.

Тонкие химические технологии, 2008
The effect of primary aliphatic amine structure and conditions (solvent, the presence of tertiary amine) in course of its reaction with pheophorbide a and methylpheophorbide a on the yield of the final product – chlorine е6-13-alkylamide has been shown.

Rh(I)-Catalyzed Hydroamidation of Olefins via Selective Activation of N–H Bonds in Aliphatic Amines

Hydroamidation of olefins constitutes an ideal, atom-efficient method to prepare carboxylic amides from easily available olefins, CO, and amines. So far, aliphatic amines are not suitable for these transformations. Here, we present a ligand- and additive-

Grafting Nanolayers of Ni and Co Catalysts Around the Edges of Hierarchical Zeolite 13X by Leveraging the Crystal's Defects for CO2 Methanation

Carbon Energy, EarlyView.
The deactivation of nickel‐based catalysts at high temperatures poses a significant challenge in CO2 methanation processes. To address this, a strong metal–support interaction between nickel and the support was engineered by exploiting the crystal defects present in hierarchical porous zeolite 13X.

Porous Carbon Materials for Carbon Dioxide Capture

Carbon Energy, EarlyView.
This work aims to address the current status and challenges associated with the regulation of pore structures, as well as the influence of pore structures on CO2 capture. Systematic quantitative analysis of structure–property relationships, combined with machine learning approaches, can effectively evaluate the contributions of structural ...

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.
