“…The diffraction peaks in the BTMO are slightly shifted toward lower Bragg angles than those in BTO, which proves the successful doping of Mn ions in the BTO crystal, due to the presence of oxygen vacancies in BTMO . The good crystallinity of the materials can be confirmed from the well-defined and sharp peaks of diffraction. − The absence of any extra peaks in the BTMO sample confirms the complete diffusion of Mn ions inside the BTO lattice. The tetragonal crystal structure of both the samples can also be confirmed from the presence of the split diffraction peaks regarding (002) and (200) set of planes .…”

The current study depicts an exclusive technique to detect fluoride ions in water using a cost-effective self-powered sensing device using nanostructured Mn-doped BaTiO 3 as the detecting element. The device is powered by a piezoelectric nanogenerator (PENG), whose substrate was modified by addition of the Mn-doped BaTiO 3 nanomaterial and carbon nanotubes as fillers to generate high PENG output voltage sufficient for driving the fluoride detector. A highest voltage of 43.6 V and current of 1.23 μA was achieved by the modified PENG substrate. This substrate was then connected as the input to the fluoride detection film via a rectified voltage divider circuit. The device was found to detect fluorides in water mixed at different concentrations, with the highest sensor response of 32.69 and a limit of detection as low as 1.18 μM. This work enlightens a unique method to detect fluoride in a very efficient and inexpensive way.

“…When LPG was expatriated from the chamber, the total number of H + molecules declined and more and more environmental oxygen comes in contact with the sensing film and produces an − O 2 coating again. 7,8,28,[32][33][34]36,37 Thus, the resistance again reaches its initial condition. Now, this sensing film was powered by TENG as discussed above and voltage drop across the film was measured as shown in Fig.…”

This work establishes a very simple and economical preparation of paper-based triboelectric nanogenerators for self-powered liquified petroleum gas (LPG) sensing. Magnification in the output of a Triboelectric nanogenerator (TENG) was achieved using hydrothermally synthesized ZnO/SnO2. This material has been thoroughly characterized through X-ray diffraction, ultraviolet spectroscopy, field-emission scanning electron microscopy (FESEM), Fourier transform infrared analysis and Nanozetasizer. The average crystallite size of the heterostructure was obtained as 17.59 nm. Bandgap of ZnO/SnO2 material was found as 3.49 eV. FESEM exhibits that present heterostructure material exhibits spherical nature with lots of voids on the film surface. Nanozetasizer shows that the diameter of particles resides in the range 50-80 nm with an average particle size as 63.23 nm. The fabricated TENG generates the maximum output voltage of ~75 V, which is more than the output of a paper-based TENG. This TENG was used as a power source to operate a resistive LPG sensing film. The maximum response 24 and minimum response-recovery times of 120-135 ms was observed, which makes this LPG sensing device ultra-fast.

The present work focuses on synthesis of Fe3O4 magnetite core@shell type nanoparticles modified with three types of ligands: Magnetite with activated carbon (MAC), Magnetite with silica (tetraethoxysilane, TEOS, and 3-aminopropyltriethoxysilane, APTES) (MTA), and Magnetite with silica, APTES and humic acids (MTAH). The MTAH sample shows greater porosity in comparison to MTA, and MAC sample. The band gap of MTAH is 4.08 eV, which is higher than MTA (2.92 eV), and MAC (2.80 eV). Rietveld quantitative phase analysis of all derivatives was performed and compared for all three samples. The LPG sensing at room temperature shows the highest sensor response of 9.42, in comparison to 3.87 sensor response for MAC, and 4.60 for MTA. This approximately double sensor response increment is justified with the help of band gap, porosity, and size of all three the samples. The MTAH sample shows the lowest response-recovery time of 9.33 and 10.78 sec, respectively, in comparison to MAC and MTA samples.
