Summary: This study investigated the feasibility of blast furnace burden preparation using the composite agglomeration process (CAP) for titanomagnetite concentrate. The results showed that CAP optimized the particle size distribution of the feed and increased the voidage of the material layer, improving permeability index. Under specific experimental conditions, CAP achieved higher sintering yield, productivity, and RDI+3.15 compared to traditional sintering process (TSP). CAP also exhibited better agglomeration technical indexes than TSP under the same composite basicity conditions. It is an effective method for producing low-basicity sinter and reducing the proportion of expensive acid pellets in the burden.

Summary: This study investigated the agglomeration of titanomagnetite concentrate using the composite agglomeration process (CAP) and found that CAP resulted in higher yield and better product quality compared to the traditional sintering process. The improved properties were attributed to the formation of calcium ferrite and silicoferrite of calcium and aluminum group minerals in CAP, which helped overcome the negative effects of perovskite on agglomeration.

Summary: A systematic analysis was conducted on industrial iron ore sinter product and associated sinter returns, characterizing the major macro- and micro-structural types. The correlation between mechanical sinter strength and sinter microstructure was found, particularly in materials with high porosity and isolated hematite grains. The formation of microstructure types was explained by non-equilibrium solidification in the Fe2O3-Al2O3-CaO-SiO2 system.

Summary: In order to improve the permeability of sinter packed bed and efficiently utilize low-grade iron bearing minerals, the impact of returned fines embedding on productivity, yield, flame front speed (FFS), tumble index (TI), and permeability of the vanadium titanium magnetite sintering process was studied. The results showed that embedding different sizes of returned fines can increase the productivity, yield, flame front speed, and tumble index to a certain extent, with the optimal sintering indices occurring at a particle size of 3 to 5 mm for the embedded return fines. The study also found that the permeability of the sinter packed bed improves as the mass ratio of the embedded return fines increases from 0% to 50%.

Summary: Laboratory experiments were conducted to study the dissolution and penetration behaviors of MgO-based refractories in CaO-SiO2-Al2O3-MgO-TiO2 system ladle refining slags. It was found that the addition of TiO2 increases the solubility of MgO in the slags and influences the physical properties of the slags. TiO2 content affects the viscosity, surface tension, and contact angle between the slags and MgO refractory. The depth of slag penetration into the refractory shows an initial increase and then decrease. TiO2 accelerates the degradation of MgO refractories, but the suitable MgO content in the slags can mitigate this effect.

Summary: Transferrin (Tf) plays a crucial role in transporting Fe(III) into cells, but its biological function in binding and delivering other metal ions remains controversial. This study investigated the effect of non-Fe(III) metal ion binding on the conformation of Tf using urea-polyacrylamide gel electrophoresis (urea-PAGE). The results showed that metal ions like In(III), V(III), and Cr(III) caused a closed Tf conformation similar to Fe(III)-Tf, while Ga(III) and V(IV) did not. Only In(III) increased the proportion of closed Tf conformation in whole serum. These findings suggest that Tf may not act as a natural carrier for metal ions other than Fe(III), but it can bind exogenous metal ions in serum and prevent their entry into cells, reducing their toxicity.

Summary: A 3D simulation model was established to investigate the behavior of gas-liquid multiphase flow in an oxygen-rich side-blown bath smelting furnace (OSBF). The study analyzed the motion of bubbles, distribution of slag phase, flow field, and flow status in the bath during the smelting process. It was found that the gas and slag were evenly mixed, the slag iron interface fluctuation was subtle, and the turbulence of the molten iron layer was weak, which facilitated the smelting process. The effects of primary air flow, slag layer thickness, and slag viscosity on the process were also studied, providing recommendations for operation and optimization design of the OSBF.

Summary: In situ high-pressure Raman spectra of phthalic anhydride (PA) were measured using a diamond anvil cell technique up to 16 GPa. The results showed that all Raman bands shifted towards the blue region with increasing pressure, and new bands appeared. A possible Fermi resonance phenomenon was proposed at pressures above 6.6 GPa, accompanied by a potential first-order phase transition. The changes in Fermi resonance parameters, including intensity ratio, coupling coefficient, and frequency gap of unperturbed transition, were discussed.

Summary: This paper mainly focuses on studying the structure and performance of a smart knitting sensor and investigates the properties of different fabrics knitted with conductive yarns. The study reveals that the prepared knitted fabrics not only meet the requirements of air permeability standards and have good elastic recovery but also show different conductivities based on the type and size of the conductive yarn used. The research findings indicate that the conductivity of the fabric is affected by the number of conductive yarn wales and courses, and the stability of conductivity varies for different types of conductive yarns and knitting stitches before and after washing.

Summary: Chemical oxidation as a pretreatment for petroleum-contaminated soil, coupled with bioremediation, can have serious impacts on indigenous microorganisms and available nutrients. This study found that hydrogen peroxide treatments significantly promoted the removal of total petroleum hydrocarbons (TPH), especially in the initial days, and also affected the levels of dissolved nutrients. Both chemical oxidation and nutrients contribute to changes in microbial community structure and diversity. However, the long-term effects of H2O2 as a pretreatment had little impact on the soil indigenous microbial community structure and actually facilitated the continuous removal of TPH by indigenous microorganisms.

Summary: This study establishes a simulation model to investigate the lightning inductive characteristics between parallel cables. The research findings indicate that an increase in the horizontal distance between cables leads to a decrease in the cable induced voltage. Additionally, linear correlations exist between the height difference or disturbed cable length and the cable induced voltage, reaching maximum when the cables are at the same height and of equal length.
