Abstract Nitrogen doped Carbon Quantum Dots (NCQDs) is synthesized in most economical and easiest hydrothermal process. Here N-phenyl orthophenyldiamine citric acid are applied as a source of nitrogen carbon for the preparation NCQDs. The NCQDs were characterized using experimental techniques like UV−Vis absorption, FT-IR, transmission electron microscopy (TEM), X-ray Diffraction (XRD), dynamic light scattering (DLS), fluorimeter time resolved fluorescence spectroscopy. These quantum dots used to study their bactericidal activity against representative Gram-negative (E. coli P. aeruginosa) Gram-positive (B. Subtilis S. Aureus) bacterial strains by agar well diffusion method. Results shows that have maximum antibacterial against aureus with good inhibitory effect inhibition range from 2 mg mL-1 3 mL-1. also probe sensitive selective detection mercury. emission intensity has drastically quenched Hg2+ ion. Observed limit (LOD) 4.98 nM, much below than approved prescribed Environmental Protection Agency. Hence play an important role monitoring water quality. Measured yield ~ 53%. TEM image quasi-spherical shaped average size 3.5 nm.

This study presents the pequi (Caryocar coriaceum) as a new biomass source for carbon dots synthesis. The almond, usually discarded, was used precursor in one-step hydrothermal green synthesis of dots. Pequi-based (PQ-CDs) exhibited an estimated height around 8 nm, with hydroxyl, carbonyl, and amino functional groups confirmed by FTIR, bright blue emission, quantum yield 17.9%. PQ-CDs were employed fluorescent sensors Fe3+ ions, based on quenching fluorescence interaction ions. sensor demonstrated linear relationship between increase ion concentration, LOD 1.16 μmol L-1, well below maximum concentration drinking water established WHO. are cost-effective highly sensitive alternative ions detection samples from Cariri region.

Abstract This leading-edge overview delivers an all-inclusive knowledge on fundamentals, state-of-the-art, and technicalities of two important polymer categories filled with graphene quantum dots, namely conjugated polymer/graphene dots rubber/graphene nanocomposites. According to the literature up till now, facile efficient fabrication methods, like in situ polymerization, solution mixing, melt blending, etc. have been reported for these derived hybrids. The ensuing based nanocomposites were inspected microstructural, electrical conductivity, charge transportation, thermal/mechanical resistance, fluorescence properties, allied valuable physical features. Incidentally, we notice promising applications inimitable hybrids gas/molecular/piezoelectric sensors, supercapacitors, biomedical areas. Nevertheless, due limited reports applied sides conjugated/rubbery matrices, future research attempts seem indispensable resolve challenges optimized/controlled processing also unveil structure-property-performance links synergistic mechanisms developing next generation industrial level
