“…The results clearly showed that the element Sb (Sb 3d 3/2 peaks at 540.42 and 539.54 eV), the element Bi (Bi 4f 5/2 peaks at 164.07 and 162.41 eV, Bi 4f 7/2 peaks at 158.61 and 157.11 eV) and the element Sn (Sn 3d 5/2 peaks at 496.97 and 493.72 eV, Sn 3d 3/2 peaks at 485.49 and 483.76 eV) exist in their corresponding co-doped ZnO samples [25,26]. Further, the position of these peaks confirms the presence of co-doping ions in multi valence state such as Sb 5+ and Sb 3+ in Mn, Sb co-doped ZnO, Bi 5+ and Bi 3+ in Mn, Bi co-doped ZnO and Sn +4 and Sn +2 in Mn, Sn co-doped ZnO samples, respectively.…”

“…For example, MOS sensors are particularly useful for monitoring VOCs due to such advantages as low cost, rapid sensor response and recovery times, and ease of e-nose manufacture [7–11]. However, certain MOS sensors are not widely used for interior environmental-monitoring applications, such as monitoring indoor air quality in buildings, because they are often limited by the lack of selectivity towards VOCs from similar chemical classes.…”

Electronic-nose (e-nose) instruments, derived from numerous types of aroma-sensor technologies, have been developed for a diversity of applications in the broad fields of agriculture and forestry. Recent advances in e-nose technologies within the plant sciences, including improvements in gas-sensor designs, innovations in data analysis and pattern-recognition algorithms, and progress in material science and systems integration methods, have led to significant benefits to both industries. Electronic noses have been used in a variety of commercial agricultural-related industries, including the agricultural sectors of agronomy, biochemical processing, botany, cell culture, plant cultivar selections, environmental monitoring, horticulture, pesticide detection, plant physiology and pathology. Applications in forestry include uses in chemotaxonomy, log tracking, wood and paper processing, forest management, forest health protection, and waste management. These aroma-detection applications have improved plant-based product attributes, quality, uniformity, and consistency in ways that have increased the efficiency and effectiveness of production and manufacturing processes. This paper provides a comprehensive review and summary of a broad range of electronic-nose technologies and applications, developed specifically for the agriculture and forestry industries over the past thirty years, which have offered solutions that have greatly improved worldwide agricultural and agroforestry production systems.

“…It is well known that oxygen tends to site at grain bound barriers in polycrystalline films both at grain boundaries and also on the surface. These oxygen spaces may produce potential barrier for charge carriers [31][32][33]. So, we think that this change is due to the decreasing oxygen deficiencies because of the micro structural compositional change of the grains, in addition to other phenomena such as disorder and defects at the grainboundaries.…”

The interest in NiO films has been growing fast due to their importance in many applications in science and technology. NiO films are an attractive material and are used common application area such as an antiferromagnetic layer, p-type transparent conducting film, electrochromic devices and chemical sensors. Also, NiO is a good candidate for p-type semiconductor films due to its wide band gap energy from 3.6 to 4.0 eV. In this work, NiO films have been grown on glass substrates by ultrasonic spray pyrolysis technique using NiCl 2 .6H 2 O as spraying solution. Films have been annealed at 500 °C in air during 1 h. Optical measurements of NiO film have been carried out at room temperature using a UV-VIS spectrophotometer. Band gap of as-deposited and annealed films have been calculated by using optical method and found as 3.67 eV and 3.7 eV, respectively. Thicknesses of the films have been determined by filmetrics thin film measurement system. Surface properties of the films have been investigated with an atomic force microscope and electrical resistivity measurements have been performed by a four probe set-up. Consequently, the optical, electrical and surface differences have been determined between as-deposited and annealed NiO films produced by ultrasonic spray pyrolysis.
