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 ...

Ultra‐Thick Carbon Microhoneycomb Cathode for High‐Capacity Lithium‐Oxygen Batteries

Carbon Energy, EarlyView.
This work demonstrates ultra‐thick biochar‐derived carbon microhoneycomb cathodes for lithium‐oxygen batteries. The penetrated macrochannels serve as highly efficient pathways for Li+ and O2 and provide abundant accommodation space for the discharge product. The optimized cathode achieved a high areal capacity of 38.2 mAh cm–2, providing guidelines for

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.

A Mononuclear Scenario for the Copper‐Catalyzed Monooxygenation of Phenolic Substrates

Chemistry – A European Journal, EarlyView.
ABSTRACT Whereas a dinuclear pathway applies to the monooxygenation of phenols by the type 3 copper enzyme tyrosinase, a mononuclear pathway has been identified for the same reaction in corresponding small‐molecule systems. DFT calculations of five copper model complexes reveal that the latter mechanism is energetically feasible, identifying all ...

The Metabolism and Toxicity of Quinones, Quinonimines, Quinone Methides, and Quinone-Thioethers

Current Drug Metabolism, 2002
Quinones are ubiquitous in nature and constitute an important class of naturally occurring compounds found in plants, fungi and bacteria. Human exposure to quinones therefore occurs via the diet, but also clinically or via airborne pollutants. For example, the quinones of polycyclic aromatic hydrocarbons are prevalent as environmental contaminants and ...

Quinones of brevibacterium

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1974
Abstract Two unusual menaquinones have been revealed during examination of Brevibacterium thiogenitalis and Brevibacterium vitarumen. Both microorganisms were found to contain menaquinones-8 (II-H2) and -9 (II-H2). The major quinone of the former was menaquinone-9 (II-H2) while that of the latter was menaquinone-8 (II-H2).

Antitumour Quinones

Mini-Reviews in Medicinal Chemistry, 2005
Quinones still comprise one of the largest classes of antitumour agents. For example, the anthracycline antibiotics are among the most utilised anticancer agents ever developed. Many other quinones were tested for their anticancer activity. Though there are general and well-established mechanisms for quinone toxicity, the exact contribution of the ...
