The synthesis of recyclable ionic liquid-supported imidazolidinone catalyst I and its application in 1,3-dipolar cycloaddition of nitrone with α,β-unsaturated aldehyde with high performance were described. Most importantly, the catalyst I can be recovered and recycled for up to five runs without observing significant decrease in catalytic activity.

Utilization of reusable catalysts and reaction media has recently been an area of interest to devise a sustainable approach. Interestingly, photoinduced reversible deactivation radical polymerization (photoRDRP) of glycidyl methacrylate (GMA) is achieved with reusable and magnetically separable nano zero-valent Iron (nZVI). This resulted in well-defined poly(glycidyl methacrylate) (PGMA) (upto 22700 g mol) with a low dispersity (Đ ≤ 1.

In this project, a new heterogeneous polymeric ionic liquid catalyst based on vinylimidazole, stabilized on magnetic nanoparticles )FeO@AlO@[PBVIm]HSO) was prepared. Then the desired catalyst was identified by TGA, FT-IR, VSM, and TEM techniques. The efficiency of this catalyst was measured in the synthesis of chromene, xanthene, and dihydropyrimidinone.

In our previous study, the whole cells containing an aldo-keto reductase (yhdN) and glucose dehydrogenase (GDH) were constructed and applied in a stereoselective carbonyl reduction reaction to prepare (S)-NEMCA-HEPE, being a key chiral intermediate of (S)-Rivastigmine which is widely prescribed for the treatment of Alzheimer's disease. Although the conversion and enantiomeric excess (e.e.

The efficient removal of Mn(II) from wastewater is crucial for safeguarding water quality, yet existing adsorbents face significant challenges, including high costs, poor resistance to ionic interference, and scalability limitations. This study addresses these challenges by utilizing abundant natural sandy sediment (SS) as a substrate to load unsaturated MnO via in-situ oxidation, creating a novel adsorbent (MOSS). MOSS exhibits a remarkable Mn(II) adsorption capacity of 1.

The widespread use of neodymium-iron-boron (NdFeB) magnets has raised concerns about the environmental impact of their disposal, prompting the need for sustainable recycling strategies. Traditional solvents used in recycling are toxic and flammable, making them risky to use. Ionic liquids are safer and greener options with low vapor pressure, high stability, and less flammability.
