“…In contrast, the sol-gel method offers a more tailored approach to hematite synthesis [34,35]. This technique relies on the hydrolysis and condensation of metal alkoxides or salts to form a sol, which subsequently undergoes gelation and calcination to yield hematite nanoparticles [36,37].…”

Microwave-based reactions have gained traction in recent years due to their ability to enhance reaction rates and yield while reducing energy consumption. Also, according to the conception of ‘waste to materials’, various waste feeds are intensively sought to be tested. The experimental setup of this study involved varying pH levels, oxidation agents, and precipitation agents to optimize the synthesis process of iron red based on waste iron sulfate. The selection of oxidation and precipitation agents was found to significantly influence the pigment synthesis process. Various oxidizing agents, including hydrogen peroxide and atmospheric air, were evaluated for their effectiveness in promoting the oxidation of ferrous ions to ferric ions, essential for pigment formation. Additionally, different precipitation agents such as sodium hydroxide and ammonia solution were assessed for their ability to precipitate iron hydroxides and facilitate pigment particle formation. The characterization of synthesized pigments revealed promising results in terms of quality and color properties. Helium Ion Microscopy (HIM) analysis confirmed the formation of well-defined pigment particles with controlled morphology. X-ray diffraction (XRD) studies provided insights into the crystalline structure of the pigments, indicating the presence of characteristic iron oxide phases. By improving this technology, waste iron sulfate can be efficiently transformed into valuable iron pigments, offering a sustainable solution for waste management while meeting the growing demand for high-quality pigments.

Reusing and recycling wastes to produce new materials are seen as costeffective, sustainable solution for the economic and environmental problems especially in the agricultural and construction sectors in the worldwide. In the paper, four groups of waste samples including both agricultural and industrial wastes (tincal waste, Bayburt stone waste, tea waste, eggshell waste, marble dust waste and peanut shell waste) were produced by mixing in different ratios. The radiation protection parameters were found by Phy-X/PSD code and radiation shielding abilities of the samples were examined. Mass attenuation coefficient data were also compared by Xcom. In addition, spectroscopic results were provided based on XRD and SEM-EDS spectroscopic techniques. It is obtained that the shielding performances of the samples including tincal waste and Bayburt stone waste with the highest amount of marble dust waste and eggshell waste are the highest, respectively. The lowest protection property is obtained for the sample with Bayburt stone waste with marble dust waste and peanut shell waste consisting of lower Ca and higher C contents. It is observed that there is a direct relation between the amount of Ca and the radiation shielding capability of the samples. It is also determined that neutron shielding potential is the highest for tincal waste with marble dust and tea waste. It can be concluded that the newly prepared samples consisting of wastes in order to support reusing and recycling have good protective properties and use of the samples as replacement materials instead of cement or aggregate can be recommended.
