Boron nitride (BN) nanostructures (= nanoBN) are struc‐ tural analogues of carbon nanostructures but display different materials chemistry and physics, leading to a wide variety of structural, thermal, electronic, and ...

Abstract Biochar yield prediction plays a critical role in optimizing pyrolysis processes and advancing sustainable biomass utilization. This study introduces a hybrid machine learning framework that integrates Decision ...

In the present study, the biochar produced by fast pyrolysis at 350 C of untreated and acid treated cellulose are evaluated as supports of CueRu@Pt core-shell nanoparticles (2.9 e3.5 nm) for the electro-oxidation of meth...

This study investigated the fast pyrolysis of biomass in fluidized-bed reactors using computational fluid dynamics (CFD) with an Eulerian multifluid approach. A detailed analysis was conducted on the influence of various...

This study examines the fast pyrolysis of rosehip seed waste (RSW) in a fluidized bed reactor, evaluating its potential for syngas production and effective waste valorization. The fluidization behavior of sand/RSW mixtur...

Waste materials from agricultural and food packaging usage pose significant health and environmental challenges, where the main source of waste originates from plastics and protein-based amino acids, and their thermal de...

BackgroundTar-rich coals serve as an important coal-based oil and gas resource in China, while their pyrolysis product distribution is governed by the coupling effects of coal properties and reaction conditions. Therefor...

The technology for the synthesis of nanocrystals (NCs) of pure ZnO and ZnO doped with a magnetic Mn impurity in concentrations of 2% and 4% by ultrasonic spray pyrolysis has been developed. The structural, morphological ...

The extensive reliance on fossil resources for fuels and platform chemicals has raised critical concerns over resource depletion and increasing greenhouse gas emissions. To address these challenges, microalgae offer a pr...

Lithium iron phosphate/carbon (LFP/C) nano-perticles were successfully synthesized at 500 °C through the pulse jet spray pyrolysis with use of a citric acid aqueous solution. SEM observation and particle size analyzer s...

Abstract The dual challenges of waste biomass disposal and escalating contamination by inorganic, organic, and emerging microplastic pollutants demand sustainable, circular remediation strategies. Biochar, a carbon-rich,...

The quality of the bio-oil was improved through co-feeding of peanut shells with plastics and the useof clinoptilolite, a natural zeolite, as catalyst. The main advantage of using this catalyst is its low cost. The mater...

ZnO nanorods (NRs) were grown on fluorine doped tin oxide (FTO) substrates at low temperatures (90 °C) from Zn2+ precursors in alkaline media previously seeded with ZnO nanoparticles. These were deposited onto the FTO s...
