Biowaste utilization as a carbon source and its transformation into porous carbons have been of great interest to promote environmental remediation owing biowaste's cost-effectiveness useful physicochemical properties. In this work, crude glycerol (CG) residue from waste cooking oil transesterification was employed fabricate mesoporous glycerol-based (mCGPCs) using silica (KIT-6) template. The obtained mCGPCs were characterized compared commercial activated (AC) CMK-8, material prepared...
Abstract This study addresses the challenges of biodiesel production costs and waste oil disposal by investigating use low-cost as a feedstock. The impact heating temperature on yield trace metal levels is examined using response surface methodology (RSM). Optimal conditions for high yields (95–98%) from canola are determined with methanol/oil ratio 12:1, 1 wt% catalyst, 60-min reaction time. For crude bioglycerol, optimal involve 4.25:1, 2.93 119.15-min Elemental analysis reveals presence...
Cis- or Z-configuration is required for the plant growth-promoting activity of cinnamic acid (CA), whereas E-form inactive. Herein, we describe encapsulation E-CA by cucurbit[7]uril (CB7) and show that photoisomerization reactions can be more efficiently controlled in aqueous solutions utilizing this supramolecular approach. Measurements UV–visible absorption proton NMR spectra at different pH values confirm its methyl ester, methyl-E-cinnamate (MC), form stronger 1:1 host–guest complexes...
A new fluorescent dye (4PBZC) comprising coumarin (C), piperazine (P), and benzimidazole (BZ) was designed, prepared, complexed to cucurbit[7]uril (CB7) detect carnosol (CAR), an anti-breast cancer drug, in sub-nanomolar concentrations utilizing the supramolecular indicator displacement assay strategy, CB7-assisted pKa shift, CB7-retarded photoinduced electron transfer process. The host-guest complexation confirmed by UV-visible absorption, fluorescence, 1H NMR spectroscopy, which...
A novel multifunctional fluorescent molecule (Bz-8HQ) was synthesized from the linkage of benzimidazole (Bz) and 8-hydroxyquinoline (8HQ) molecules its response to multiple stimuli investigated spectroscopically.
