A new energetic fullerene derivative [60]­fullerene-poly­(glycidyl nitrate) (C60-PGN) was synthesized through a modified Bingel reaction of C60 and bromomalonic acid PGN ester in the presence of amino acid and dimethyl sulfoxide. The obtained product was characterized by nuclear magnetic resonance, Fourier transform infrared spectroscopy, and ultraviolet–visible spectroscopy. Results confirmed that C60-PGN was synthesized successfully. The thermal decomposition analysis of C60-PGN was investigated by differential scanning calorimetry and thermogravimetric analysis with infrared spectroscopy, which revealed that C60-PGN exhibits good resistance to thermal decomposition up to 200 °C. The kinetic parameters of the thermal decomposition of C60-PGN were also obtained from the differential thermal analysis data by Kissinger and Ozawa–Doyle methods, with E a = 170.85 and 168.29 kJ·mol–1, respectively. C60-PGN exhibits stability higher than that of any other known polynitrofullerenes.

A new functionalized fullerene derivative [60]fullerene poly(3-azidomethyl-3-methyl oxetane) (C 60 -PAMMO) was synthesized for the first time using a modified Bingel reaction of [60]fullerene (C 60 ) and bromomalonic acid poly(3-azidomethyl-3-methyl oxetane) ester (BM-PAMMO). The product was characterized by Fourier transform infrared (FTIR), ultraviolet-visible (UV-vis), and nuclear magnetic resonance (NMR) spectroscopy analyses. Results confirmed the successful preparation of C 60 -PAMMO. Moreover, the thermal decomposition of C 60 -PAMMO was analyzed by differential scanning calorimetry (DSC), thermogravimetric analysis coupled with infrared spectroscopy (TG-IR), and in situ FTIR. C 60 -PAMMO decomposition showed a three-step thermal process. The first step at approximately 150 °C was related to the cycloaddition of azido groups (-N 3 ) with [60]fullerene. The second step was ascribed to the remainder decomposition of the PAMMO main chain at approximately 230 °C. The final step was attributed to the burning decomposition of amorphous carbon, the main chain, N-heterocyclic and carbon cage at around 510 °C.

Taking the brazing mechanism of alumina ceramics and kovar alloys as the main research object, based on the molybdenum–manganese metallization method, the influence of the direct and indirect brazing processes on the morphology of the final connected layer is explored. Combined with SEM, EDS, the microscopic morphology, and hermeticity affecting the final ceramic–metal composite component is discussed. Finally, through the indirect brazing process, various ceramic–metal composite joints with good airtightness satisfying the requirements were prepared.

Nowadays, it is still a great challenge to fabricate MoS2 QDs using porous metal-organic frameworks (MOF) as template, because MOF structure is prone to collapse during solvothermal reaction, so as...
