MBG powders were synthesized according to the method proposed by Yan et al. [21 (link)]. In a typical synthesis for the basic MBG (molar ratio of Si/Ca/P = 80:15:5), 4.0 g of the non-ionic block polymer Pluronic P123 (molecular weight Mw = 5800, Sigma-Aldrich, Steinheim, Germany) were dissolved in 60 g of ethanol (96%) and stirred at room temperature for 1 h. Next, 6.7 g of tetraethyl orthosilicate (99%, Sigma-Aldrich, Steinheim, Germany), 0.73 g of triethyl phosphate (99.8%, Sigma-Aldrich, St. Louis, MO, USA), 1.4 g of calcium nitrate-tetrahydrate (dissolved in 6 mL deionized water, Merck, Darmstadt, Germany) and 1.0 g of 0.5 M HCl were added. The complete solution was stirred at room temperature for 24 h and casted afterwards in petri dishes left for drying at room temperature for 1 d to undergo an evaporation-induced self-assembly process. The obtained gel was dried at 60 °C for 3 h, grinded and then calcined at 700 °C for 7 h. Obtained glass particles were manually grinded and fractionated by vibration sieving with 500, 250, 180 and 45 µm sieves. Strontium-containing MBG were produced in the same way by gradually substitution of the calcium by strontium [22 (link)], using strontium nitrate (Sigma-Aldrich, Steinheim, Germany) as Sr2+ source. Due to the lower solubility, Sr(NO3)2 was dissolved beforehand in 20 mL deionized water.

Alkaline earth metal oxide catalysts supported on BEA zeolite were synthesized by the wet impregnation method. The ammonium form of commercial BEA zeolites, which were purchased from Zeolyst International (Kansas City, KS, USA), was used for the synthesis of the catalytic material. These zeolites were characterized by SiO2/Al2O3 ratios of 25 and 300, respectively. The zeolites were subjected to long-term calcination for 15 h in an air atmosphere at 500 °C in order to convert the ammonium form of the zeolites to hydrogen form. The active phase precursors were magnesium nitrate hexahydrate (Mg(NO3)2·6H2O), calcium nitrate tetrahydrate (Ca(NO3)2∙4H2O), and strontium nitrate (Sr(NO3)2) purchased from SIGMA-ALDRICH (St. Louis, MO, USA, ACS reagent, 99%). The content of MgO, CaO, and SrO in the prepared catalytic materials was 10 wt%. The studied calcium catalyst systems were then calcined in a muffle furnace in an air atmosphere at 500 °C (for SrO catalysts, the temperature of calcination was 600 °C) for 4 h.

Sr/F bioactive glass nanoparticles (Sr/F-BGNPs) were synthesized using the sol-gel process under the basic condition based on the previous studies [39 (link),40 (link),41 (link)]. Firstly, 0.32 M of ammonium hydroxide, 6 M of Milli Q water, 0.035 M sodium fluoride (Sigma Aldrich, St. Louis, MO, USA), and 14 M of ethanol (Sigma Aldrich, St. Louis, MO, USA) were mixed and stirred at 500 rpm for 30 min in a 500 mL of Erlenmeyer Flask. Then, the solution was gradually added with tetraethyl orthosilicate (0.28 M) (TEOS, Sigma Aldrich, St. Louis, MO, USA). Next, the mixed solution was stirred for 8 h. Particles were then collected by centrifugation. They were then incorporated with calcium nitrate tetrahydrate (0.14 M) (Sigma Aldrich, St. Louis, MO, USA) and strontium nitrate (0.42 M) (Sigma Aldrich, St. Louis, MO, USA). The synthesized particles were calcined at 680 °C for 3 h with the rate of heating at 3 °C/min to allow the incorporation of calcium (Ca), strontium (Sr), sodium (Na), and fluoride (F). Then, the particles were thoroughly cleaned with ethanol.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
