Liquid–solid triboelectric nanogenerators (L–S TENGs) can generate corresponding electrical signal responses through the contact separation of droplets and dielectrics and have a wide range of applications in energy harvesting and self-powered sensing. However, the contact between the droplet and the electret will cause the contact L–S TENG’s perfo...

Novel chemi-resistive gas sensors with strong detection capabilities operating at room temperature are desirable owing to their extended cycle life, high stability, and low power consumption. The current study focuses on detecting NH3 at room temperature using lower gas concentrations. The co-precipitation technique was employed to produce pure and...

In this study, a facile synthesis of fluorescence carbon dots (CDs) from local oak apple (O-CDs) in the mountainous region of Zagros was performed through hydrothermal treatment. The characterization of O-CDs was carried out by SEM, TEM, FTIR, EDX, Mapping, lain scan, and AFM, respectively. In addition, the fluorescence of CDs was quenched by efavi...

For the first time, the influence of Cerium (Ce3+) on the structural, microstructural, Fourier infrared spectroscopy, and LPG sensing behaviour of CoCr2-xCexO4 (CoCrCe) is described in this study. The solution combustion technique was used to create the CoCrCe samples. All samples were sintered for 3 h at 600 °C to achieve a pure crystalline nature...

Avalanche phenomenon uses critical pump power to produce extreme nonlinear behavior from small disturbances, and has gradually become known. Here, it is reported that the strong green up-conversion emission produced in NaBi(WO4)2 phosphor by the positive feedback enhancement of the energy transfer process. The power dependence indicates that the ph...

Recently the emissions of volatile organic compounds (VOCs) in the atmosphere have increased dramatically with rapid development of urbanization and industry. This led to a large decline in air quality around the world, which resulted in a heavy impact on human health. Therefore, new/cheap detection devices for VOCs are of high interest. Formaldehy...

Sensors for rapid and reliable detection of biomolecules are crucial for clinical medical diagnoses. Here, a rapid, ultra-sensitive, magnetic-assisted biosensor based on resonance Raman scattering at MoS2@Fe3O4 composite nanoflowers is presented. Raman shifts and X-ray photoelectron spectra indicated that the composite was formed via Fe–S covalent ...
