Techno‐Economic Assessment of Biomethane and Biohydrogen Production From Victorian Wheat Straw

Carbon Energy, EarlyView.
Techno‐economic assessment of biomethane and biohydrogen production from Victorian wheat straw. Off‐grid renewable photovoltaic energy with a price down to 0.95 ¢/kWh was applied. Both approaches can make positive profits and negative carbon footprints.

Challenges of Bio‐Syngas Conversion to High‐Value‐Added Liquid Chemicals and Fuels via COx Hydrogenation

Carbon Energy, EarlyView.
Converting biomass‐derived syngas into value‐added fuels and chemicals offers a promising route toward carbon neutrality, yet unfavorable H2/COx ratios, elevated CO2 levels, and trace impurities pose persistent obstacles. This review examines strategies spanning syngas conditioning, impurity‐tolerant catalyst development, and integrated process design,

Coupling Fluid Neutrals to Gyrokinetic Plasma Dynamics for Edge and SOL Turbulence Simulations

Contributions to Plasma Physics, EarlyView.
ABSTRACT Accurate modeling of turbulent transport in magnetic confinement fusion devices requires extending first‐principles gyrokinetic simulations from the core to the edge and scrape‐off layer (SOL), where additional physics—particularly plasma–neutrals interactions—must be included.

Securing Water in a Changing Climate: A Transient Solar Desalination Model for the Sundarbans, Bangladesh

Energy Science &Engineering, EarlyView.
This graphical abstract presents a solar‐powered reverse osmosis (RO) system for the Sundarbans, Bangladesh. Mechanistic modeling reveals a critical seasonal mismatch: during the monsoon, feed water salinity peaks (24.8 ppt) while solar irradiance drops significantly.

Fine coal beneficiation: comparison study of the separation efficiency of a dense medium cyclone and flat-bottom cyclone [PDF]

Near-gravity material (NGM) is the fraction of coal particles with a relative density within a range of ± 0.1 of the relative density of the separating medium during coal washing. High levels of NGM in coal impede classifier separation efficiency because

Improving Daily Rainfall Downscaling Over Taiwan's Complex Terrain With Surface‐Wind‐Informed Deep Learning Model

International Journal of Climatology, EarlyView.
An encoder–decoder architecture (EDA) dynamically downscales coarse‐resolution climate fields (0.25°) to high‐resolution outputs (0.05°) over Taiwan, improving the representation of fine‐scale spatial variability and localized extremes by incorporating both rainfall and surface winds to maintain physical consistency.

Numerical simulation of magnetite segregation in a dense medium cyclone

, 2006
Numerical simulations of turbulent driven flow in a dense medium cyclone with magnetite medium have been conducted using Fluent. The predicted air core shape and diameter were found to be close to the experimental results measured by gamma ray tomography.
