Starving for Data: Eating Disorders Prevalence and Research Gaps in Southern Africa

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Studies reporting prevalence estimates of eating disorders in Southern Africa are scarce. To fill this gap, the present Research Forum reviews existing literature on the prevalence of eating disorders, including as assessed by clinical interviews, screeners, and self‐reported behaviors, among individuals in Southern Africa.

What Can Charcoal Reflectance Tell Us About Energy Release in Wildfires and the Properties of Pyrogenic Carbon?

open access: yesFrontiers in Earth Science, 2018
Here we explore how charcoal formation under different heating regimes and circumstances leads to chars of different physical properties. In order to do this we have undertaken 1) carefully controlled laboratory experiments that replicate the different ...

“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 ...

Comparative Analysis of Graphitization Characteristics in Bamboo and Oak Charcoals for Secondary Battery Anodes

open access: yesCrystals
When compared to natural graphite, artificial graphite has advantages such a longer cycle life, faster charging rates, and better performance. However, the process of producing it, which frequently uses coal, raises questions about the impact on the ...

Changes of wood anatomical characters of selected species of Araucaria- during artificial charring - implications for palaeontology

open access: yesActa Botânica Brasílica, 2017
Charcoal is widely accepted as evidence of the occurrence of palaeo-wildfire. Although fossil charcoal remains have been used in many studies, investigation into the anatomical changes occurring during charring are few. The present study analyses changes

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.
