“…However, the PDI-Asp/BBC complexes have an average size about 500 nm, indicating the aggregation of PDIs. The complex ratio and quenching constants ( K sv ) were calculated according to the linear Benesi–Hildebrand expression and Stern–Volmer plots, respectively. , Figure S9 showed there was a linear relationship between the measured absorbance [1/( A – A 0 )] at 533 nm and 1/[BBC] ( R = 0.996), implying the 1:1 complex ratio between PDI-Asp and BBC. From Figure B we can obtain the quenching constants ( K sv = 2.00 × 10 –5 M –1 ).…”

Developing a rapid and simple method for the detection of berberine chloride (BBC), one kind of natural antibiotic, is significant to ensure reasonable control and administration of antibiotic residues in food and other feed. In this report, a sensitive and selective fluorescent probe based on a water-soluble perylene diimide derivative (PDI-Asp) has been screened for the detection of berberine chloride (BBC). The sensing performance and mechanism of this probe were systematically investigated by using UV–vis and fluorescence spectroscopic techniques. Meanwhile, the influencing factors of probe structures on the sensing performance were also addressed. It was identified that the formation of supramolecular complex between BBC and PDI-Asp through synergy of electrostatic and π–π interactions promoted a rapid and fluorometric assay for BBC in 100% aqueous systems. The detection limit for BBC was found to be as low as 28 nmol/L. Finally, PDI-Asp was a highly promising fluorometric probe for the direct determination of BBC in practical samples. To the best of our knowledge, this is the first report of PDI-based probe for detecting small biomolecules in pure aqueous solution. We believe that this approach will not only extend the sensing scope of PDIs but also contribute to understanding the mechanism of the interaction between BBC and PDIs, and it will provide some useful information for the design of PDI-based probes for other small biomolecules.

“…According to the working principle of the nano sensor, when the organic gas contacts the surface of nanomaterials, chemiluminescence will occur, and its signal will produce different properties of the monitored organic gas and nanomaterials. However, the sensor made of a single nanomaterial can only monitor a certain organic gas, if a variety of different nanomaterials are as sensing units to make sensor arrays, different organic gases can be monitored (El Khalidi et al, 2019;Lv and Kumar, 2020;Song et al, 2020;Yan et al, 2019). Therefore, before monitoring the near zero emission of SF6, the sensor array should be designed based on the catalytic luminescence of nanomaterials.…”

<p>Aiming at the problems of long monitoring time, low sensitivity and low precision of traditional methods, a nano sensor for near zero emission monitoring of sulfur hexafluoride (SF6) was proposed. The characteristics of SF6 gas were analyzed. The infrared spectrum of SF6 gas was obtained by spectral absorption method. The laser of Laixi series is used as the hardware of SF6 gas monitoring. The nano sensor array is designed, and the near zero emission state of SF6 is monitored by using the nano sensor node optimization method. The experimental results show that compared with the traditional method, the nano sensor method can shorten the monitoring time (less than 3.0 seconds), improve the monitoring sensitivity and accuracy. The results show that the method can monitor the air emission and environmental pollution accurately and timely.</p>

“…Electrochromism , is a phenomenon, shown by some material (known as electrochromic materials), of an electrical bias induced change in optical properties as can be seen through the naked eye and/or in terms of modulation in absorption or transmission spectrum. An electrochromic device (ECD), fabricated utilizing the electrochromic properties of any material, is mainly used for applications in electronic curtains, smart windows, color filters including heat shielding, and so forth. − However, recently such devices have gotten a lot of interest due to additional applications in various fields like storage devices, − sensors, − special displays, − and other electronic circuits . A typical ECD comprises thin films of electrochromic materials, ion transport material (electrolyte), and sometimes counterions that help to enhance the performance of the device.…”

A dual purpose solid state electrochromic diode has been fabricated using polythiophene (P3HT) and ethyl Viologen (EV), predoped with multiwalled carbon nanotubes (MWCNTs) and MoS2. The device has been designed by considering two important aspects, first, the complementary redox activity of P3HT and EV and second, the electron holding properties of MoS2 and MWCNTs. The latter is found to enhance the electrochromic performance of the solid state device. On the other hand, the complementary redox nature gives the asymmetric diodic I–V characteristic to the device which has been exploited to use the electrochromic device for rectification application. The MoS2 nanoflower and MWCNTs are synthesized by one-step hydrothermal and pyrolysis techniques and well characterized by scanning electron microscopy (SEM), X-ray analysis (XRD), and Raman spectroscopy. Electrochromic properties of the device have been studied in detail to reveal an improvement in device performance in terms of faster speed and high coloration efficiency and color contrast. In situ bias-dependent Raman spectroscopy has been performed to understand the operation mechanism of the electrochromic diode which reveals (bi-)polaron formation as a result of dynamic doping eventually leading to color change. A half-wave rectifier has been realized from the electrochromic diode which rectifies an AC voltage of frequency 1 Hz or less making it suitable for low frequency operation. The study opens a new possibility to design and fabricate multipurpose frequency selective electrochromic rectifiers.
