Study on the Synergistic Effects and Optimization of Flotation Reagent Blends Under Low Reagent Consumption

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Under low reagent dosage, the flotation performance of diesel as a collector was enhanced, and the synergistic mechanism of diesel blended with oleic acid and CTAB was investigated. Results showed that compared to pure diesel, the oleic acid blended system (Blend A) increased clean coal yield by 81.52% to 92.24%, while the CTAB blended system (

DNA metabarcoding reveals greater plant diversity than morphological seed analysis of bird feces

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Fruit‐eating birds drive seed dispersal in recovering tropical ecosystems, shaping forest regeneration. Molecular techniques, such as DNA metabarcoding, enable diet analysis from feces and can provide complementary frugivory data where dispersal is infrequent, as well as aid in seed identification in hyper‐diverse regions lacking ...

Histology and fossil diagenesis of a pterosaur tooth from the Crato Formation (Lower Cretaceous of Brazil)

open access: yesThe Anatomical Record, EarlyView.
Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

Integrated bioconversion of starchy and hemicellulosic fractions of macauba oil presscake into ethanol by nonconventional yeasts

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Co‐fermentation of hexoses and pentoses from plant biomass to ethanol is a strategy to increase ethanol production from lignocellulosic materials and add value to residues from agroindustrial chains. The macauba (Acrocomia aculeata) is an oleaginous palm‐tree species considered to contribute to development in some regions of Brazil.

Market potential of biobased chemicals: a qualitative network analysis of adoption dynamics in South Africa’s bioeconomy

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The premise of a bioeconomy is the replacement of nonrenewable and unsustainable fossil‐derived resources and associated technologies with more sustainable alternatives. The adoption of biobased chemicals contributes toward the growth of a bioeconomy and is dependent on market and industry requirements.
