“…Bayazeed et al had observed quenching and enhancement effects in the same peak at 676 nm upon addition of Hg 2+ and As 3+ ions to CQD160 derived from banana leaves. 55 The starting precursor thus plays an important role in determining the optical response of CQD160 to the toxic metal ions. Our CQD160 derived from plumeria leaves can thus be used as a true ON–OFF sensor for selectively detecting Hg 2+ and As 3+ ions in water.…”

“…We noticed that the O1s, and N1s has peak positions nearly same but that have occurred differences in the peaks broadening, which clarifies the physiosorbed interaction observed. [51] The Cl2p peaks in Figure S3(b) are composed of RhÀ B, which has a binding energy of 197.07 eV, which is shifted to 198.22 eV for conjugate. From this peak shift of Cl 2p, it can be inferred that chlorine groups are actively participating in strong interaction among RhÀ B and BZ-EXT and are forming non-fluorescence complex.…”

Rhodamine B (Rh−B) is a well‐known carcinogenic agent with potential health risks, yet it is frequently used as a food adulterant in developing countries. This study presents the synthesis and characterization of a Broussonetia Zeylanica extract (BZ‐EXT) from a plant for the rapid, efficient, and sensitive colorimetric sensing of Rh−B. The limit of detection (LOD) and limit of quantification (LOQ) were found to be 0.41 μg/mL and 1.31 μg/mL, respectively. We demonstrating superior sensitivity compared to conventional methods using DI water as a solvent. Furthermore, the practical applicability of the developed material was successfully tested in real samples, yielding estimated values of Rh−B are 0.76 μg/mL and 0.52 μg/mL, respectively. The pH dependent colorimetric sensing performance of the BZ‐EXT for Rh−B detection was found more efficient at aqueous pH value of 9.2. These results highlight the potential of the BZ‐EXT as a promising tool for rapid and sensitive detection of Rh−B food adulteration in real samples.

“…Concerning reliability and accuracy, quantum sensors, such as quantum magnetometers, atomic spectrometers, or fluorescence sensors based on carbon quantum dots, offer high precision and accuracy in measuring physical parameters [4,60]. These types of sensors can provide more reliable and accurate water quality measurements [126,127], flow rate, and pressure [128,129], thus surpassing the limitations of traditional sensors. In addition, quantum sensors may better detect low concentrations of contaminants in water or wastewater compared to conventional sensors.…”

The vital role of civil engineering is to enable the development of modern cities and establish foundations for smart and sustainable urban environments of the future. Advanced sensing technologies are among the instrumental methods used to enhance the performance of civil engineering infrastructures and address the multifaceted challenges of future cities. Through this study, we discussed the shortcomings of traditional sensors in four primary civil engineering domains: construction, energy, water, and transportation. Then, we investigated and summarized the potential of quantum sensors to contribute to and revolutionize the management of civil engineering infrastructures. For the water sector, advancements are expected in monitoring water quality and pressure in water and sewage infrastructures. In the energy sector, quantum sensors may facilitate renewables integration and improve grid stability and buildings’ energy efficiency. The most promising progress in the construction field is the ability to identify subsurface density and underground structures. In transportation, these sensors create many fresh avenues for real-time traffic management and smart mobility solutions. As one of the first-in-the-field studies offering the adoption of quantum sensors across four primary domains of civil engineering, this research establishes the basis for the discourse about the scope and timeline for deploying quantum sensors to real-world applications towards the quantum transformation of civil engineering.
