Fossil-free ironmaking is indispensable for reducing massive anthropogenic CO2 emissions in the steel industry. Hydrogen-based direct reduction (HyDR) among most attractive solutions green ironmaking, with high technology readiness. The underlying mechanisms governing this process are characterized by a complex interaction of several chemical (phase transformations), physical (transport), and mechanical (stresses) phenomena. Their interplay leads to rich microstructures, hierarchy defects...
Iron making is the biggest single cause of global warming. The reduction iron ores with carbon generates about 7% dioxide emissions to produce ≈1.85 billion tons steel per year. This dramatic scenario fuels efforts re-invent this sector by using renewable and carbon-free reductants electricity. Here, authors show how make sustainable reducing solid oxides hydrogen released from ammonia. Ammonia an annually 180 million ton traded chemical energy carrier, established transcontinental logistics...
An in-depth investigation was carried out on five Chinese coals using a range of advanced analytical techniques focused specifically extracting structural parameters. Detailed investigations were Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, and X-ray diffraction followed by peak deconvolution data analysis. Correlations established for parameters determined from different techniques. The FTIR showed good linear relationships between the apparent aromaticity (fa(FTIR))...
Saline water is widely used as an alternative resource for agriculture to overcome the freshwater shortage in arid and semiarid regions. But long-term using of saline irrigation would negatively affect soil properties crop production, salinity should be properly managed reduce risks. In this study, with five levels electrical conductivities (ECiw) at 1.3 (CK), 3.4, 7.1, 10.6, 14.1 dS·m−1 were irrigate winter wheat summer maize annual double cropping system North China Plain (NCP) from 2006...
In the context of dwindling freshwater resources, it is imperative to comprehensively evaluate crop productivity and soil resource sustainability when considering use saline water for irrigation (SWI). This study aimed investigate effects SWI on salinity variation flat sowing cotton (Gossypium hirsutum L.) through a comprehensive 15-year field experiment conducted in North China Plain, encompassing six levels (ECiw 1.3, 3.4, 7.1, 10.6, 14.1, 17.7 dS m−1, respectively). The results revealed...
The thermodynamics of possible reactions, including gasification and reduction in carbon–carbon dioxide–sodium or potassium carbonate systems was analyzed first. And then, the reactions graphite coke with CO2 this system were studied kinetically by temperature programmed thermogravimetry. results showed that carbon conversion curve shifted to a lower zone after Na2CO3 K2CO3 added, more susceptible than be catalyzed K2CO3. Ten kinetic equations adopted simulate reaction process using method...
A parametric study of ReaxFF for molecular dynamics simulation graphitization amorphous carbon was conducted. The responses to different initial configurations, time steps, simulated temperatures, and parameter sets were investigated. results showed that a step shorter than 0.2 fs is sufficient the using both Chenoweth 2008 Srinivasan 2015 sets. networks produced at 300 K are similar each other, with first peak positions pair distribution function curves located between graphite sp2 bond...
As a typical application of fintech, the robo-advisor has increasingly gained attention over last decade. However, most research regarding focused on its development issues such as performance improvement and regulation, while limited paid to trust. This extends literature by investigating trust influencing mechanism robo-advisors mixed method approach. Specifically, we identified six salient factors qualitative interviews proposed model based transfer theory. was tested via survey 230...
