“…The film without Cd (In‐Ga‐O) exhibits a bandgap ≈3.38 eV, in good agreement with the literature (3.3–3.4 eV) . With increasing Cd incorporated, the bandgap keeps a continuous redshift, and reaches 2.47 eV at x = 8 (InGaCd 8 O) which is very close to the reported values (2.2–2.8 eV) for CdO . The extracted E g is plotted as a function of the Cd ratio in Figure b.…”

“…[28] With increasing Cd incorporated, the bandgap keeps a continuous redshift, and reaches 2.47 eV at x ¼ 8 (InGaCd 8 O) which is very close to the reported values (2.2-2.8 eV) for CdO. [25,29,30] The extracted E g is plotted as a function of the Cd ratio in Figure 3b. Based on linear fitting, the absorption spectra can be roughly divided into two different regions.…”

“…Hence, it is suggested that with increasing Cd ratio (x), CdO grains would be separated out from the In‐Ga‐Cd‐O network and gradually grow up. A similar phenomenon had been reported in other ternary oxide compounds such as In‐Zn‐O, Zn‐Ga‐O, and Cd‐Ga‐O . Additionally, to get more structural information, the average grain size of the InGaCd 6 O sample was calculated using the FWHM of (002) and (111) dominant peaks through the Scherrer's method, featuring an average grain size of ≈37 nm.…”

“…[8] X-ray diffraction (XRD) measurements were performed on the InGaCd x O thin films, but no distinct signals were observed due to their weak crystallinity or/and small film thickness (<30 nm). To get a deep insight of the microstructure evolution [6,25,26] Additionally, to get more structural information, the average grain size of the InGaCd 6 O sample was calculated using the FWHM of (002) and (111) dominant peaks through the Scherrer's method, [27] featuring an average grain size of %37 nm. Shown in Figure 3a-e are the atomic force microscopy (AFM) images of some representative InGaCd x O films.…”

Concerning the revolutionary future of electronic devices, high‐performance solution‐processable semiconductors have earned increasing academic and industrial research interests. In this paper, we synthesize In‐Ga‐Cd‐O semiconductor thin films via a solution method. Transparent amorphous/nanocrystalline oxide thin films with small surface roughness have been grown by controlling the relative ratio of Cd‐content. The present thin‐film transistor with an optimized Cd‐ratio exhibits a saturation field‐effect mobility up to 10 cm2 V−1 s−1, an on/off current ratio of ≈1.3 × 109, and a threshold voltage shift of ≈2.6 V under −5 V gate bias of 10 000 s, which are superior or comparable to those reported values of solution‐processed conventional In‐Ga‐Zn‐O counterparts. Our results indicate that the proposed In‐Ga‐Cd‐O semiconductor would endow a promising transparent amorphous/nanocrystalline active material for electronic devices.

“…Therefore, cadmium poisoning is considered an occupational hazard putting at least 512,000 workers in the United States at health risk annually [4]. The hazardous effects of cadmium on the body organs are extensive, such as the liver, kidneys, bones, hematopoietic and respiratory disorders [5][6][7].…”

Background: The protective effects of Montelukast (Mont), as an anti-inflammatory drug, against cadmium-induced kidney cell damage have already been studied and identified. Since the significant part of cadmium nephrotoxicity is caused by oxidative stress, this in vivo and in vitro study was conducted to investigate the possible role of Montelukast antioxidant properties in the protection. Methods: In the in vivo section, 42 rats were treated in seven groups of six rats as follows: Control; Cadmium Chloride (CdCl2) control; Montelukast control; CdCl2 plus Montelukast treatment; CdCl2 with Montelukast pre-treatment; Vitamin E control; CdCl2 plus Vitamin E treatment. In the in vitro section, human embryonic kidney cells (HEK293) were treated with CdCl2; Montelukast; Combined CdCl2 and Montelukast; Vitamin E; Combined CdCl2 and Vitamin E. Results: Montelukast, in both treatment and pretreatment forms, reduced serum urea, creatinine, and potassium levels compared to CdCl2 group, in vivo. Similar to vitamin E, the pre-treatment with Montelukast was associated with a significant decrease in Nitric Oxide (NO) and Total Antioxidant Capacity (TAC) in serum and renal tissue, and a significant increase in Glutathione Peroxidase (GPX) activity in serum compared those in the CdCl2 group. In the in vitro section of the study, Montelukast significantly reduced Malondialdehyde (MDA) and NO while the TAC level, Superoxide Dismutase (SOD), and the GPX activity increased significantly. Conclusion: Overall, the antioxidant effects of Montelukast appear to play a prominent role in preventing the renal toxicity due to cadmium exposure.
