Effect of Pyrolysis Temperature on Mechanistic Transformation for Adsorption of Methylene Blue on Leached Rice‐straw Biochar

For adsorption of methylene blue, a Toxicity characteristic leaching procedure leached biochar was tested. Rice straw biochar obtained from slow pyrolysis at 400, 500, and 600°C, respectively, was TCLP leached to produce leached biochar, BL4, BL5, and BL6. BL4, BL5 and BL6, respectively, had maximum Langmuir adsorption of 26. 87, 51. 34, and 18. 83 mg/g for BL4, BL5 and BL6, respectively. Non-ionic lactone ring opening in the presence of MB under alkaline conditions that was approved by XPS and FTIR studies. MB'ssorption on leached biocharBL4 and BL6 was characterized by the ion exchange mechanism and weak intermolecular factors of attraction, respectively. For four cycles, desorption of MB and regeneration from BL5 was tested with methanol and 0. 1 M HCl as the stripping solvent for four cycles. In comparison to 0. 01 M HCl, MB recovery was enhanced with methanol.

Novel cardo‐type heat‐resistant polyimides bearing 9H‐xanthene and polymer‐based nanocomposite consisting of NH2‐terminated TiO2: Synthetic strategies, extraction of methylene blue dye, and biological activities

PIs had outstanding thermal stability with 10% weight loss at temperatures between 426 and 528 °C, glass transition temperature ranges in the range of 292-310 °C, with weight residual at 700 °C ranging from 55% to 68% under N2 atmosphere, according to a report of thermal behavior. The 6FD-derived PI against the A431 cells had an IC50 value of 29. 3 M, which was in vitro anticancer activity. The removal efficiency figures were above 80. 62% in the following study: Methylene blue dye adsorption from aqueous solution by the obtained PIs and PIB/HBP@TiO2 was carried out.

Effects of toluidine blue O and methylene blue on growth and viability of pancreatic cancer cells

Our aim in this research was to determine whether methylene blue and toluidine blue O could be used to slow down pancreatic cancer cell growth and survival. TBO and MethB reduced the growth and viability of Hs 766T cells in a dose-dependent manner relative to vehicle-treated controls, as shown by MTT and trypan blue exclusion assays. However, both MethB and TBO decreased BACE activity and the levels of APLP2 CTFs in Hs 766T cells, although APLP2 CTFs were also reduced.
