An Ultrasensitive Ethanol Gas Sensor Based on a Dual-Nanoparticle In₂O₃/SnO₂ Composite by Cheng Zhang, Ze Zhang, Yao Tian, Lingmin Yu, Hairong Wang

“…The ultrasensitive response to ethanol can be attributed to the faster electron migration rate and the increase in oxygen-absorbing sites caused by the n-n heterojunction in the nanocomposite. Due to its low detection limit, good repeatability, and relatively high responses in high humidity, this sensor has a potential application in exhaled breath detection.…”

Study of the application prospects of film detectors for estimation of α-radiation density by Dana S. Yerimbetova, Marina Konuhova, Artem L. Kozlovskiy, Umitali N. Tuichiyev

“…During the experiments, good convergence of the results of structural changes determined by optical spectroscopy and X-ray diffraction methods was established. These changes are caused by the processes of interaction of α-particles with a polymer detector, characterized by deformation distortion of the molecular chains of the polymer, leading to the formation of defects that affect changes in optical and electron density. …”
