چکیده
The 3D metal–organic framework (MOF), MIL-88B, built from the trivalent metal ions and ditopic 1,4-Benzene dicarboxylic acid linker (H2BDC), distinguishes itself other MOFs for its flexibility high thermal stability. MIL-88B was synthesized by a rapid microwave-assisted solvothermal method at power (850 W). iron-based [Fe3.O.Cl.(O2C–C6H4–CO2)3] exposed oxygen iron content of 29% 24%, respectively, which offers unique properties as an oxygen-rich catalyst energetic systems. Upon dispersion in organic solvent integration into ammonium perchlorate (AP) (the universal oxidizer systems), MOF particles AP matrix uniform (investigated via elemental mapping using EDX detector). Therefore, MIL-88B(Fe) could probe decomposition with exclusive formation mono-dispersed Fe2O3 nanocatalyst during decomposition. evolved can offer superior combustion characteristics. XRD pattern TGA residuals confirmed α-Fe2O3 final product. catalytic efficiency on behavior assessed DSC TGA. solely demonstrated enthalpy 733 J g−1, while AP/MIL-88B(Fe) showed 66% higher 1218 g−1; main exothermic temperature decreased 71 °C. Besides, resulted decrease activation energy 23% 25% Kissinger Kissinger–Akahira–Sunose (KAS) models, respectively.

Microwave-assisted flexible synthesis of 7-azaindoles.
7-Azaindoles are versatile building blocks, especially in medicinal chemistry, where they serve as bioisosteres of indoles or purines. Herein, we are presenting a robust and flexible synthesis of 1,3- and 1,3,6-substituted 7-azaindoles starting from nicotinic acid derivatives or 2,6-dichloropyridine, respectively. Microwave heating dramatically accelerates the penultimate reaction step, an epox...

متن کاملT1-MRI Fluorescent Iron Oxide Nanoparticles by Microwave Assisted Synthesis
Iron oxide nanoparticles have long been studied as a T₂ contrast agent in MRI due to their superparamagnetic behavior. T₁-based positive contrast, being much more favorable for clinical application due to brighter and more accurate signaling is, however, still limited to gadolinium- or manganese-based imaging tools. Though being the only available commercial positive-contrast agents, they lack ...
متن کاملSynthesis of Nanoporous Metal Organic Framework MIL-53-Cu and Its Application for Gas Separation
MIL-53-Cu has been synthesized hydrothermally and has been used for the first time for gas separation. MIL-53-Cu shows adsorption capacities of 8.1, 0.7 and 0.5 m.mol/g, respectively, for CH4, CO2 and H2 at 30 bar and 298 K. The high CH4 adsorption capacity of MIL-53-Cu maybe attributed to the high pore volume and large number of open metal sites....
