“…Instead, rGO was acquired by laser irradiation onto a simple filter paper with controlled parameters. 21,22 However, the work was limited by its lower electrical and physicochemical properties due to the insufficient penetration of laser fluence into the substrate, restricted by its thickness. The continued investigations found an attractive, biodegradable, and eco-friendly natural polymer, shellac, as a natural resource to suppress the limitations of our reported process.…”

“…The obtained material was thoroughly characterized for its structural information through x-ray diffraction (XRD) and optical properties from UV-visible spectroscopy. Further, the surface area was obtained using Brunauer-Emmett-Teller analysis and morphological information from scanning electron microscopy and transmission electron microscopy [16,30,31]. The rGO was hand-scrapped from the filter paper to prepare a stock solution of 15 mg ml −1 in ethanol.…”

Graphene-based materials are found to be the excellent acceptors of chemiluminescence resonance energy transfer (CRET) phenomenon. Due to the presence of π-conjugated planar structure, these materials reported to quench the chemiluminescence (CL) signal. Based on this fact, herein, for the first time the recovery of quenched CL signal from different graphene-based materials is successfully obtained through the catalytic activity of onsite temperature. The maximum recovery of quenched signal at optimum temperature of 70 ℃ was found to be 1440 % from the 10 mg/ml reduced graphene oxide paper analytical devices (rGO-PADs), leaving the recovery of Flash graphene (FG) and Laser Induced graphene materials (LIG) as 895 %, 521 % respectively for the same conditions via generation of π-conjugated carbon radicals. Catechin, an antioxidant, was analyzed from 0.1 nM to 500 nM to interpret the generation of carbon radicals from graphenized materials. The proposed smartphone enabled onsite heating recovery model was validated with the lower limit of 94 pM (27.3 pg/ml) of catechin concentration without any advanced photodiodes or instrumentation. The validation was performed in real samples of green tea (GT1 and GT2). This method of CL recovery can be a future model of indicating the purity of graphene-based materials without use of advanced instrumentations.

An additional component that is also very important in this tool is an air detection sensor, with component type MQ-135, this component can measure the concentration of CO, CO2, SO2, and NO2 gases, giving results in PPM (Parts per Million) [4]; [5]; [6]; [7]; [8]. Likewise with the BME280 component which functions to measure the temperature, pressure & humidity of the environment.…”

Modern industry urgently needs air quality detectors, which are used to detect air pollutants, such as; CO, CO2, SO2, and NO2, which are not good for the health of living beings and the environment. In this study, we created a tool that can monitor the gas and provide results in PPM (parts per million). Sensors will collect parameter data and environmental data will be output to the server.The conclusions as follows: first, The design of the air pollution detection device uses the MQ-135 gas sensor with IOT-based technology to detect CO2, SO2, and NO2 gases. The input from the gas sensor is processed through the ESP-8266, will produce an air quality index output, thus displaying the index in various places/locations, which will be displayed on the monitor, and, the second is The latest implementation of this air pollution detection tool using the MQ-135 can identify hazardous air levels of CO2, SO2, and NO2 gases, which then provide indications and information to android application users and computers, with an air quality index/value.
