Summary: Using a new technology of melt pretreatment-microwave selective heating process, this research extracted well-catalyzed CaTiO3 from low-grade titanium-bearing resource by making use of the difference in microwave absorption ability, density, and melting point of titanium-bearing components with others in TBFS. The study also found that melt pretreatment promoted the transition of titanium from low-valent to high-valent, which enhanced the difference of microwave absorption ability among components in TBFS. The CaTiO3 product obtained showed good catalytic characterization with a band gap of 2.25 eV.

Summary: Ironmaking blast furnace (BF) is an energy-intensive chemical process. This study investigates the dynamic behaviors of BF under different scenarios of blast temperature (BT) decrease using a transient-state BF model. The responses of different BF regions to the BT change are found to be different, with the regions near BF gas inlet responding more promptly and significantly. This research provides a cost-effective tool to study time-related behaviors in the BF domain when BT changes occur.

Summary: Oxygen blast furnace ironmaking utilizes high oxygen enrichment in the blast to achieve "zero carbon footprint" production. The increase in oxygen enrichment initially leads to an increase in fuel or coke rate, impacting the flow and thermochemical behaviors and the cohesive zone height in the furnace. The analysis also shows the influence of blast temperature and top pressure on coke rate and productivity, with top pressure having a more significant effect at higher oxygen enrichments.

Summary: Blast furnace dust (BFD) generated from the ironmaking process causes soil and water pollution. In this study, a selective catalytic reduction (SCR) catalyst was developed using BFD as a raw material. The BFD-400 catalyst showed the best SCR performance with over 90% nitrogen oxides (NOx) conversion in the temperature range of 225°C to 350°C. The catalyst also exhibited excellent resistance to sulfur and water in coal-fired flue gas due to weak adsorption energy calculation.

Summary: The feasibility of converting high-iron electric furnace ferronickel slag and high-calcium blast furnace ferronickel slag to refractory materials was assessed. The addition of sintered magnesia was found to suppress the negative effects of FeO and CaO in the slag, resulting in the formation of refractory materials. The refractory material derived from EFFS showed higher refractoriness, lower bulk density, and larger compressive strength compared to that derived from BFFS.

Summary: Plants exposed to suboptimal environmental conditions often have reduced crop yields, but pre-exposure to mild stress can prepare plants for subsequent challenges. This study investigated the effects of herbicide sub-doses on oxidative stress caused by waterlogging and the potential for waterlogging to mitigate herbicide injury in soybean crops. The results showed that early exposure to a sub-dose of oxyfluorfen enhanced the plants' ability to tolerate waterlogging, while pre-treatment with the herbicide paraquat did not have significant effects. Additionally, pre-exposure to waterlogging reduced the damage caused by herbicides, suggesting the existence of cross-tolerance between herbicides and waterlogging in soybean plants.

Summary: The effects of multiwall carbon nanotubes (MWCNTs) on the electrical, dielectric, and piezoelectric properties of the ferroelectric ceramic/castor-oil polyurethane (PUR) composite films were investigated. The addition of MWCNTs significantly enhanced the electrical and piezoelectric properties of the composite films by acting as conductive bridges between the lead zirconate titanate (PZT) particles. The dispersion of MWCNT nanoparticles also improved the poling effectiveness and increased the d(33) coefficient of the three-phase piezoelectric composites.

Summary: In this study, a flexible electrochemical immunosensor based on CeO2 nanorods immobilized with CRP antibody was developed for the detection of cardiovascular disease biomarker. The CeO2 nanorods were obtained by microwave-assisted hydrothermal method and characterized by XRD, TEM, and XPS. The immunosensor's working electrode was prepared by dispersing the nanorods in organic solvent, functionalizing them with cystamine and glutaraldehyde, and then modifying them with CRP antibody. The developed immunosensor exhibited good reproducibility, a wide detection range, and a low detection limit, making it suitable for point-of-care applications.

Summary: NaPO3-20Ga(2)O(3)-xNa(2)WO(4) (x = 0, 1, 3, 5 and 10% mol) tungsten gallium-phosphate glasses were synthesized and evaluated as potential intrinsic glass scintillators due to their high chemical stability and excellent optical properties. Increasing Na2WO4 content led to a decrease in OH- groups and the presence of sole W6+ species. The glasses exhibited high transmittance (around 90%) over a wide spectral range (400 to 2500 nm) and luminescence emission characteristic of the WO42- complex with average lifetimes ranging from 32 to 20 μs. Cryogenic temperatures resulted in a significant increase in luminescence emission for the NaPGaW glasses.

Summary: In the past decade, there has been a growing interest in studying energy systems for the combined management of power vectors. Most of the published works focus on finding the optimal design and operations of Multi Energy Systems (MES). However, for newcomers to this field, understanding how to achieve the desired optimization details while controlling computational expenses can be challenging and time-consuming. This paper presents a novel approach to analyzing the existing literature on MES, with the aim of guiding practical development of MES optimization. Through the discussion of six case studies, the authors provide a mathematical formulation as a reference for building the model and emphasize the impact of different aspects on the problem nature and solver selection. In addition, the paper also discusses the different approaches used in the literature for incorporating thermal networks and storage in the optimization of multi-energy systems.

Experimental validation results show that thermal radiation accounts for a significant proportion of the total heat exchange in the reactor and a large amount of radiant energy exists in the important spectral range of supercritical water. Enhancing radiative heat transfer can effectively increase the temperature of the reaction medium and the gasification rate.
