“…Among the wide variety of gashouse emissions, halogen source gases which include chlorine and bromine contribute to ozone depletion due to their longer lifetimes in the atmosphere (Vallero, 2019). Those gasses destroy the ozone layer that preserves the earth of the UV radiation and prevents a temperature raise (Wexler, 2014). Consequently, to quantify the chlorofluorocarbons (CFCs) emissions is key to evaluate the environmental impacts of this process in the ozone layer and consequently to the global warming.…”

Ataxia is the inability to coordinate voluntary movement and can present with a variety of symptoms involving dyscoordination of gait and extremity movement, slurred speech, and abnormal eye movements. Ataxia can be divided into either cerebellar or sensory. Cerebellar ataxia originates from damage to the cerebellum or its connecting tracts, while sensory ataxia is a result of damage to the afferent sensory pathways such as the dorsal column and large myelinated proprioceptive fibers.

“…The saturation resistance values were the same for 7%, 24%, and 51% RH, which indicates stable response for low humidity environments. For higher moisture content, 71%RH and 95%RH, the sensor response increased due to high affinity of NH 3 for hydronium ion (H 3 O + ) [59] on the surface of PANI. The mechanical stability of sensor F-1 was tested by bending it 1000 times over different diameters in the range 7.8 to 10.7 mm.…”

Metal oxide-Polyaniline (PANI) nanocomposites have shown improved gas sensing characteristics attributed to formation of a p-n junction between the n-type metal oxide and the p-type PANI. The charge transport, grain boundary depletion region, and intragrain resistance are studied to understand the gas sensing mechanism of pristine metal oxide gas sensors. However, gas sensing mechanisms for metal-oxide/PANI nanocomposites have not been studied extensively. In this work, we have studied the gas sensing mechanism of SnO2/PANI nanocomposites using electrochemical impedance spectroscopy (EIS), and temperature dependent gas sensing experiments. Well-defined SnO2 nanoclusters were observed in the PANI matrix. The n-type SnO2 was covered by p-type PANI, and a depletion region was formed at the interface. The presence of the p-n junction depletion region was confirmed by impedance spectroscopy. The polarons in PANI were trapped by NH3 leading to change in the width of the conducting path due to rearrangement of charge carriers along the depletion region. The change in the conduction path along with the trapped polarons enhanced the sensor response. For higher loadings of SnO2, the depletion region was deformed, and the sensor response decreased due to non-uniform boundaries. The nanocomposite showed maximum sensitivity at 35 °C. 1 wt% SnO2 with respect to aniline precursor in in-situ synthesis showed the best response of 37.8% for 100 ppm NH3 at 35 °C. The response was stable for low humidity levels upto 51 %RH. The response increased for higher humidity levels. The sensor response increased from 0.17 to 2.99 upon bending at 7.8 mm diameter due to cracks in the surface. The sensor showed only 10% variation in response after 9 months.
