Journal ArticleDOI
Hard-Soft Carbon Composite Anodes with Synergistic Sodium Storage Performance
Fei Xie,Zhen Xu,Anders C. S. Jensen,Heather Au,Heather Au,Yaxiang Lu,Vicente Araullo-Peters,Alan J. Drew,Yong-Sheng Hu,Maria-Magdalena Titirici,Maria-Magdalena Titirici +10 more
Journal ArticleDOI
A revised mechanistic model for sodium insertion in hard carbons
Heather Au,Hande Alptekin,Anders C. S. Jensen,Anders C. S. Jensen,Emilia Olsson,Emilia Olsson,Emilia Olsson,Christopher A. O’Keefe,Tom Smith,Maria Crespo-Ribadeneyra,Thomas F. Headen,Clare P. Grey,Qiong Cai,Alan J. Drew,Maria-Magdalena Titirici +14 more
TL;DR: In this article, the authors proposed a mechanistic model in which sodium ions store first simultaneously and continuously at defects, within interlayers and on pore surfaces, and pore filling occurs during the plateau region, where the densely confined sodium takes on a greater degree of metallicity.
Journal ArticleDOI
Recent advances in hydrothermal carbonisation: from tailored carbon materials and biochemicals to applications and bioenergy
Sabina A. Nicolae,Heather Au,Pierpaolo Modugno,Hui Luo,Anthony E. Szego,Mo Qiao,Liang Li,Wang Yin,Hero J. Heeres,Nicole D. Berge,Maria-Magdalena Titirici,Maria-Magdalena Titirici +11 more
TL;DR: In this paper, the authors present an overview on the latest trends in hydrothermal carbonisation including biomass to bioenergy conversion, upgrading of hydro-thermal carbons to fuels over heterogeneous catalysts, advanced carbon materials and their applications in batteries, electrocatalysis and heterogeneous catalysis and finally an analysis of the chemicals in the liquid phase as well as a new family of fluorescent nanomaterials formed at the interface between the liquid and solid phases.
Journal ArticleDOI
