To address climate change and environmental concerns, the chemical process industries are increasingly adopting green technology exploring eco-friendly waste management practices. Deep Eutectic Solvents (DES) have emerged as promising solvents with diverse applications in separation processes, catalysis, drug design, a lot more. However, ideal way for modeling ionic interactions within hydrogen-bond acceptor (HBA) during DES synthesis remains uncertain, theoretical insight on formation mechanism of energetically stable DESs from choline chloride (CHL) urea (URE) is yet to be explored. In this study, we investigate different approaches (no bond, generic or single bond) molecules thermodynamic feasibility forming an using through calculations (PM3, HF, DFT). Our findings indicate that choice approach does not significantly affect outcomes across calculation levels. The H-X pathway emerges most viable route CHL: GLC synthesis, offering strong binding energy high exothermicity. This provides robust solution synthesizing potential various industries. Researchers can consider alternative levels when DFT becomes cost-prohibitive optimize computational costs. study contributes valuable insights into design promoting environmentally sustainable cost-effective processes.

Abstract The development of sustainable chemistry underlying the quest to minimize and/or valorize waste in carbon‐neutral manufacture chemicals is followed over last four five decades. Both chemo‐ and biocatalysis have played an indispensable role this odyssey. particular developments protein engineering, metagenomics bioinformatics preceding three decades a crucial supporting facilitating widespread application both whole cell cell‐free biocatalysis. pressing need, driven by climate change mitigation, for drastic reduction greenhouse gas (GHG) emissions, has precipitated energy transition based on decarbonization defossilization organic production. latter involves biomass CO 2 as feedstock green electricity generated using solar, wind, hydroelectric or nuclear energy. use polysaccharides feedstocks will underpin renaissance carbohydrate with pentoses hexoses base bio‐based solvents polymers environmentally friendly downstream products. availability inexpensive solar led increasing attention electro(bio)catalysis photo(bio)catalysis which turn leading myriad innovations these fields.

Metschnikowia pulcherrima ELM-GS-3 was isolated from damaged Granny Smith apples and identified via MALDI-TOF MS ITS sequencing (97.89% similarity, NCBI database). Pulcherrimin production confirmed on FeCl3-supplemented media by maroon-red pigment formation microscopic analysis. Food waste-derived media, including potato peel, onion skin, watermelon rind extracts, diluted molasses, were evaluated for biomass production. Onion skin extract yielded the highest (9.78±0.1 g/L) pulcherrimin (7.63±0.6 g/L), followed molasses rind. FTIR analysis iron presence, while SEM revealed an amorphous microporous 3D structure. Absorbance peaked at 420 nm in alkali solution, consistent with low solubility except alkaline conditions. The pigment’s profile, alkali, aligns its stability characteristics observed literature. This study demonstrates potential of food waste biotechnological relevance M. ELM-GS-3.

This study highlights the synthesis, characterization, and catalytic application of a novel copper(II) complex, Cu(II)(FTL), where FTL represents 2-amino-4-(4-fluorophenyl) pyrazole ligand. Spectroscopic analyses confirmed successful coordination ion through nitrogen atoms pyrazole's amino ring groups. The potential Cu(II)(FTL) was evaluated for green oxidation phenol using hydrogen peroxide (H₂O₂) as oxidant. Kinetic studies revealed Michaelis constant (K_m) 44.7 mM turnover number (k_cat) 2.7 × 10⁻⁷ s⁻¹ catalyzed reaction, compared to K_m = 37.6 k_cat 3.5 unanalyzed reaction. higher value in presence catalyst suggests lower binding affinity phenol, consistent with mechanism H₂O₂ is primary substrate activated by copper center. relatively low indicates slow rate, potentially due stable intermediate formation or product release. Despite these limitations, demonstrates environmentally friendly oxidation, paving way further optimization mechanistic exploration.
