Reconceptualizing Out‐of‐Field Teachers' Professional Development and Classroom Implementation: A Boundary Crossing Approach

Science Education, EarlyView.
ABSTRACT Reform‐oriented instruction is advocated in secondary science, encouraging students to engage with the experimental and epistemic practices of science. It is challenging for teachers though, especially for out‐of‐field teachers. This study focuses on biology and chemistry teachers who are called to teach middle‐school physics.

Extraction of Vanadium from CaO–SiO2–MgO–Al2O3 Slags Based on Vaporization of Vanadium Pentoxide

steel research international, EarlyView.
In the present article, fundamental reaction mechanisms for the extraction of vanadium from CaO–SiO2–Al2O3 slags based on vaporization of V2O5 are investigated. Several parameters influencing the vanadium extraction are analyzed. The results make it possible to develop innovative methods for extracting vanadium from slags.

Effect of Coordination Structure of Iron Ions on Iron Oxide Activity Coefficients in the CaO‐SiO2‐FeO‐Fe2O3 Slags at 1573 K Under Oxygen Partial Pressures Between 10−9 and 10−4 atm

steel research international, EarlyView.
Activity coefficients of FeO and FeO1.5 in CaO‐SiO2‐FeO‐Fe2O3 melts have been investigated from the perspective of the coordination structures of iron ions. γFeO are higher than γFeO1.5$$ \gamma_{\text{FeO}_{1.5}} $$. In addition, γFeO1.5$$ \gamma_{\text{FeO}_{1.5}} $$ increases with increasing the ratio of Fe3+(oct) pct./Fe3+(tetr) pct., which ...

Influence of Carbon Material Properties on Slag‐Foaming Dynamics in Electric Arc Furnaces: A Review

steel research international, EarlyView.
This article examines how the properties of the carbon materials affect the slag foaming, emphasizing the need for strategies to improve the effectiveness of biochar, such as pelletizing or blending with coke. Biocoke appears as promising but underexplored option for enhancing slag foaming.
