In this work, TiO2-doped carbon aerogel (TiO2/CA) was synthesized from sugarcane bagasse hydrothermal, freezedrying, and carbonization methods. The effects of the calcination temperatures of 400, 500, 600, 700, and 800 oC were also evaluated. The obtained TiO2/CA exhibits an ultralow density (0.021-0.032 g/cm3 ) and porosity of more than 97 %. The asprepared TiO2/CA was applied in photodegradation of methylene blue (MB) with the effects of dose sample and pH were also investigated.

“SKD-61 steel finds extensive application in various sectors, including the marine industry where materials must withstand harsh aquatic conditions. In this study, we employ the Grey-Taguchi approach to optimize surface roughness (Ra), cutting force (Fc), and material removal rate (MRR) when hard-milling SKD-61 steel in pure minimum quantity lubrication (MQL) and nanofluid MQL environments, aligning with the demands of marine engineering

Compare to other documents, our study was for the first time validated the quality criteria of ICP-MS for analyzing nineteen metal levels in wastewater samples. The application of this method was then tested by analyzing nineteen metal levels in twenty-three wastewater samples in the Tham Luong Canal in Ho Chi Minh City. Based on these results, the correlation of the concentration of these metals in wastewater samples was determined.
