Summary: The preoxidation of ilmenite affects its reduction kinetics, with high oxidation temperatures leading to slower reduction rates due to the formation of pseudobrookite. The effect of oxidation temperature on reduction kinetics is mainly manifested in nucleation/nuclei growth and chemical reactions. Ilmenite oxidized during preoxidation process has advantages of high conversion degree and low energy consumption in subsequent smelting process.

Summary: In this study, a preoxidation-assisted mechanism was proposed for the preparation of bismuth oxide and carbon nanofibers (Bi2O3@C-NFs) using electrospinning. By using Bi2S3 nanorods as multifunctional templates, the carbon materials were effectively protected from thermal corrosion in high-temperature calcination process. The resulting Bi2O3@C-NFs self-supporting anodes exhibited high specific capacity, superior rate performance, and outstanding cycling stability.

Summary: This study discussed the effects of adjusting the pH value of raw wastewater on the removal efficiencies of pollutants, dissolved organic matter, and sludge morphology. It also studied the changes of coagulation performance and group structure and thermal stability of flocculated sludge under the coupling action of pH/polyaluminum chloride (PAC). The results showed that adjusting the pH of raw wastewater could promote the removal efficiencies of COD and LAS and enhance the conductivity of actual cosmetic wastewater, but could not remove aromatic proteins. The highest coagulation efficiency was achieved under PAC concentration of 2.6 g/L and pH value of 6, and medium molecular weight organics were mainly removed.

Summary: This study investigated the removal performance of PS and PE microplastics using PAC and FeCl3 coagulants. Results showed that PAC was more effective than FeCl3, especially in alkaline conditions. Adsorption and complexation were the main removal mechanisms, with the formation of new bonds enhancing the efficiency.

Summary: In the past three decades, marine-derived extracts and compounds have been studied for their radioprotective activities against UV-rays, gamma (gamma)-rays and X-rays. These compounds, categorized into polysaccharides, phlorotannins, carotenoids and mycosporine-like amino acids (MAAs), demonstrate various radioprotective mechanisms including free radicals scavenging, inhibition of apoptosis, UV-ray absorption, and DNA damage-repair signaling pathways. Despite the promising potential for the development of radioprotective therapeutics, the lack of clinical studies remains a major obstacle for future research.
