“…High peaks were observed in the MgO structure at 3438 cm -1 and also in the MgO@Na 2 O structure at 3441 cm -1 , which can be due to the presence of moisture in the structure of the catalysts. Peaks with various intensities were observed in the structures of the MgO and MgO@Na 2 O nanoparticles in the range of 1400-1640 cm -1 , which can be attributed to the O-C-O tensile vibrations [25,26]. Notably, in some previous studies, the vibrations existing at 1400-1520 cm -1 , as well as the vibrations existing at 850 cm -1 , are attributed to the remaining nitrate groups in the catalysts [27].…”

Biodiesel was produced from chicken fat in the presence of MgO and MgO@Na2O nanocatalysts via transesterification. The characteristics of MgO and MgO@Na2O were examined using various analyses, including BET specific surface areas, energy‐dispersive X‐ray spectroscopy/mapping scanning electron microscopy, Fourier transform infrared spectroscopy, X‐ray diffraction, thermogravimetric analysis, and transmission electron microscopy. The maximum yields of biodiesel production using MgO and MgO@Na2O nano‐catalysts were 95.17 and 95.22 %, respectively, which are significant biodiesel yields. 1H NMR analysis was used to determine the molecular structure of the chicken fat oil and the produced biodiesel. Furthermore, the reusability of the catalysts was examined for up to six steps, showing that both catalysts can be used for up to four steps in biodiesel production.

“…Once an enzyme-like PETase or laccase has initiated the PET degradation. It is speculated that its byproducts can be further acted upon by some other enzymes produced by other microbial consortia present in the same environment [45][46][47][48][49][50][51][52][53][54].…”

The current research explored the potential of microalgal species Chlorella vulgaris and Pretreatment to remediate plastic waste. It was concluded from the results that Pretreatment had a marked effect on the cracking and alteration of plastic polymer, which helped to grow microbial species on the cracked surface as evident by Compound Microscopy (CM), Scanning Electron Microscopy (SEM), and Fourier Transformed Infrared Spectroscopy (FTIR) analysis. FTIR data also supported the notion that in the absence of any pretreatment, the microbial species were not able to mediate plastic biodegradation efficiently as the nature of functional groups was different in the presence and absence of Pretreatment. GCMS analysis revealed that the microbial specie could produce the biodegradation products which were likely to be found in the structure of PET, including alkanes ester, fatty acids, benzoic acid, and aromatics and the most toxic product of biodegradation is Bis (2-Ethyl hexyl phthalate), which is the biodegradation product of toxic ingredient of plastics that is phthalic acid.

“…Nanocatalysts are very important for chemists due to being interesting character for the large contact surface. [25][26][27][28][29] Even though numerous efficient nanosized metal catalysts have been reported for A 3 -coupling reactions, [30] the application of nanoparticles as catalysts for decarboxylative A 3 -coupling reactions scarcely studied. In fact, only four examples of such reactions were reported in literature till now.…”

The propargylamine motif is not only prevalent in a wide variety of pharmaceuticals and other biologically active compounds but also utilized as a versatile building block in organic synthesis. Among the various methods for the synthesis of propargylamine derivatives, A3‐coupling represents one of the most general and attractive routes, since it offers the possibility for the construction of complex molecules from simple starting materials (amines, aldehydes, and alkynes) in one‐step with high atom economy. However, the use of volatile alkynes is the main disadvantage of this reaction. Recently, alkynyl carboxylic acids were successfully used as easily accessible and high stable surrogates for alkynes (via in situ decarboxylation) in A3‐coupling reactions. This Focus‐Review aims to give an overview of the decarboxylative A3‐coupling reactions by hoping that it will be beneficial to elicit further research in this appealing research arena. A special emphasis is placed on mechanistic aspect of reactions which may allow possible new insights into catalyst improvement.
