Synergy Engineering of d‐Band Center and Multi‐Phase Interface Charge Transport in Ternary Co3O4/Pt/Bi2MoO6 Hierarchical Heterojunction Arrays for Superior VOCs Sensing

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel ternary Co3O4/Pt/Bi2MoO6 hierarchical heterojunction array is designed, which exhibits an impressive gas sensing activity towards volatile organic compounds (VOCs), triethylamine. The design of ternary Co3O4/Pt/Bi2MoO6 hierarchical heterojunction not only optimizes the d‐band center and thus gas molecule adsorption activity on gas–solid ...

From shape to source: sedimentary charcoal morphology as a proxy for tropical burned biomass composition

Journal of Quaternary Science, EarlyView.
ABSTRACT Sedimentary charcoal elongation is increasingly being used in paleoecology to distinguish herbaceous from woody fuel in past fires. However, the relationship between charcoal morphotypes and plant types has never been formally tested in tropical environments, despite its potential to improve understanding of fire regimes and deforestation, and
