Sodium‐Based Battery Component Design: Imitating Lithium or Forging New Paths?

Small, EarlyView.
This Perspective elucidates the decisive yet underexplored impact of cation chemistry, Na+ vs. Li+ charge carriers, on the design, selection, and formulation of their corresponding battery systems, addressing common misconceptions and the pitfalls of overreliance on Li+ design principles. Leveraging the unique characteristics of Na+, it comprehensively

Development and Validation of a Next‐Generation Mechanistic Model of the Electric Arc Furnace

steel research international, EarlyView.
This study presents a next‐generation mechanistic model of the electric arc furnace (EAF). It describes equations for all crucial processes appearing during the steel‐recycling process in an EAF, i.e., thermal, mass, and chemical. The model was parameterized and validated using industrial EAF data.

Oxy-fuel combustion of Victorian brown coal

, 2016
The consistent use of coal as a fuel source for power generation results in the significant emission of greenhouse gases into the environment. Using a low-rank coal, such as Victorian brown coal, results in a much higher CO₂ emission rate.

Study of in-flight and impact dynamics of non-spherical particles from HVOF guns [PDF]

, 2009
High velocity oxygen fuel thermal spray has been widely used to deposit hard composite materials such as WC-Co powders for wear-resistant applications. Unlike gas atomized spherical powders, WC-CO powders form a more complex geometry.

Detailed CFD simulation and experimental validation of oxy-steam fluidized bed gasification for biomass, coal, and plastic feedstocks

Energy Conversion and Management: X
Gasification of solid waste in fluidized bed reactors involves complex multi-physics processes requiring advanced modeling. While extensive CFD studies exist for biomass and coal gasification, research on plastic waste gasification remains limited.

Oxide Scale Morphology of Carbon Steels Under Novel Reheating Conditions

steel research international, EarlyView.
This study focuses on the changes in oxide scale morphology formed under simulated hydrogen and oxy‐fuel reheating gas atmospheres in comparison to natural gas‐air reheating. Several different properties were analyzed, such as pore structure, ratios of iron oxides, adhesion, and distribution of alloying elements.

Diffusion Paths for Micro Cogeneration Using Hydrogen in the Netherlands [PDF]

We estimate the diffusion of micro cogeneration systems (MiCoGen) using hydrogen produced from natural gas in the Netherlands for the 2000-2050 period on the basis of economical factors. The diffusion is important for the transition to a hydrogen economy

Observations and Experiments on the Solar Rays That Occasion Heat; With the Application of a Remarkable Property of These Rays to the Construction of the Solar and Oxy-Hydrogen Gas Microscopes [PDF]

Abstracts of the Papers Printed in the Philosophical Transactions of the Royal Society of London
Abstract The method employed by the author for obtaining, by a combination of lenses, the convergence to foci of the colorific solar rays, together with the dispersion of the calorific rays, consists in making a beam of solar light, which contains both kinds of rays, pass, after it has been converged to a focus by a convex condensing ...
