“Win‐Win” Structural Engineering of Chinese Herb Residues‐Derived Porous Graphitic Carbons: Decoupling the Porosity‐Graphitization Antagonism for Ultrahigh‐Rate Supercapacitors

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work proposes a strategy that overcomes the porosity‐graphitization antagonism in carbon materials, converting Sargentodoxa cuneata residue into porous graphitic carbons to enable sustainable, high‐performance energy storage from biomass waste. The antagonism between porosity and graphitization critically limits carbon supercapacitor performance ...

Optimally Carbonized Mangrove Wood–Derived Hard Carbon with a Soft Carbon Coating for High‐Performance Sodium‐Ion Battery Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
High‐performance SIB anodes are developed using mangrove wood–derived hard carbon, optimized through controlled carbonization temperatures and pitch‐derived soft carbon coatings. The resulting PC‐10 composite achieves a superior reversible capacity of 297.5 mAh g−1 and an 82% ICE by suppressing irreversible reactions and enhancing interfacial stability

Charcoal analysis: new source of evidences to Brazilian Archaeology.

open access: yesRevista do Museu de Arqueologia e Etnologia
Charcoal analysis is the taxonomic and quantitative study of charcoal remains found in soils or archaeological deposits, based on plant anatomy. This discipline may provide both ethnoarchaeological and palaeoecological evidences. In this paper we present

Pt Sub‐Nanoclusters on ZIF‐Derived Ultrafine CdxZn1−xS Solid Solution: High‐Performance Photoreforming Lactic Acid to H2 and Value‐Added Chemicals

open access: yesElectron, EarlyView.
This work presents ZIF‐derived ultrafine CdxZn1−xS decorated with Pt sub‐nanoclusters for efficient photocatalytic reforming of lactic acid. The catalyst achieves high H2 evolution (270.6 mmol h−1 g−1) and selective pyruvic acid production (73.1%), with mechanistic insights revealing Pt‐mediated control over reaction pathways.

Contribution of Free Fatty Acids to Emulsion Building and Stability: Understanding the Mechanism From the Case Study of a Crude Red Palm Oil (Elaeis guineensis)—Based Emulsion Consumed in Africa and Known as Achu Soup/Sauce Jaune/Ncha

open access: yesFood Chemistry International, EarlyView.
In an aqueous alkaline medium, fatty acids (from the hydrolysis of triglycerides or freely present in the oil) are ionised in order to form emulsifiers (carboxylates) which will physically stabilise the prepared emulsion. The higher the free fatty acids content of the oil and alkalinity of the solution, the higher will be the stability of the prepared ...
