Thermodynamics and Kinetics of Ammonia‐Based Reduction of Natural Hematite

steel research international, EarlyView.
Ammonia is investigated as a carbon‐free hydrogen carrier for reducing natural hematite into metallic iron. Higher temperature and smaller particle size promote faster reduction, while ammonia dissociation generates hydrogen that indirectly drives the reduction reaction. At 850 °C, high reduction degrees and porous metallic iron structures are achieved,

Eco‐ductile design of RC columns: Resolving the conflict between embodied carbon and curvature ductility

Structural Concrete, EarlyView.
Abstract Reducing embodied carbon emissions in structural design is of critical importance in combating global climate change. However, the increased material usage and heavy confinement reinforcement required to meet high ductility demands in reinforced concrete columns directly conflict with environmental sustainability goals.

Droplet generation in oxygen steelmaking

, 2015
In oxygen steelmaking, high speed oxygen jet hits the bath of molten iron and droplets are formed. This droplet generation is an important phenomenon for optimization of the steelmaking process. The present research clarified our understanding of droplet

End point prediction of basic oxygen furnace (BOF) steelmaking based on improved bat-neural network

Metalurgija, 2019
A mixed bat optimization algorithm based on chaos and differential evolution (CDEBA) is proposed for the endblow process of basic oxygen furnance (BOF) after sub-lance detection, and a prediction model based on BP neural network optimized by chaotic ...

Forces Behind South Australia's Unusual Structural Changes Since 1840

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT The agricultural sector's share of GDP in growing economies typically declines but, for a century from the early 1850s, Australia's did not. That trend is most evident for the former colony and now State of South Australia (SA). Moreover, that share for SA has been almost flat since 1980 as well, along with the agricultural sector's share of ...

Do Rivals' Trade Secret Protections Affect a Firm's Trade Credit? Evidence From the Inevitable Disclosure Doctrine

European Financial Management, EarlyView.
ABSTRACT Using the staggered adoption of the Inevitable Disclosure Doctrine (IDD) across U.S. states, this study examines whether legal protection of trade secrets granted to a firm's rivals affects the firm's trade credit when it is not similarly protected.
