Biosynthesised ZnO : Dy3+ nanoparticles: Biodiesel properties and reusable catalyst for N-formylation of aromatic amines with formic acid

Size-dependent inhibition of bacterial growth by chemically engineered spherical ZnO nanoparticles

“…In particular, ZnO has emerged as one of the most promising wide-band-gap inorganic materials for a variety of applications such as fluorescence imaging, X-ray imaging, scintillations and bacterial activity inhibitor, anticancer agent and sunscreen lotions ingredient, etc. [5,6]. It has been shown that [1] ZnO nanoparticles can be used for food safety as they can protect agricultural crops and products from food-borne pathogens.…”

Direct Synthesis of N‐formamides by Integrating Reductive Amination of Ketones and Aldehydes with CO2 Fixation in a Metal‐Organic Framework

“…[ 1 , 2 , 3 , 4 ] State‐of‐the‐art synthesis of formamides relies on the utilisation of an excess amount of the formylating agents [e. g., chloral (trichloroacetaldehyde), sodium formate, formaldehyde, acetic formic anhydride and formic acid] that react with organic amines to drive the formation of C−N bonds, yielding substantial amounts of waste and thus extremely poor atom‐economy (Figure 1a ). [ 2 , 5 , 6 , 7 ] In the context of development of sustainable chemistry, the utilisation of carbon dioxide (CO 2 )[ 8 , 9 , 10 ] and lignocellulosic biomass and their derivatives[ 11 , 12 , 13 ] for the manufacture of feedstock chemicals has attracted much interest. Although methanol derived from CO 2 has been applied for the preparation of formamides,[ 1 , 14 , 15 ] the formylation of amines via the direct use of CO 2 is a more promising but challenging target (Figure 1b ).…”
