“…The peaks at 854 cm −1 and 640 cm −1 may be attributed to C-Cl and C-Br stretching of alkyl halides, respectively. 44 The spectrum exhibits common broadband near 3400 cm −1 due to the OHstretching vibrations of free and hydrogen-bonded hydroxyl groups, indicating a strong formation of CdO material. The FT-IR spectrum of PEDOT coated on CdO nanostructure informs the peak at 650 cm −1 due to Cd-O stretching in the composite.…”

Monitoring vitamins is essential as they play a significant role in human metabolisms. Folic acid (FA), one type of vitamin B, is responsible for various functions, including new red blood cells, synthesis, and repair of DNA. Therefore, the detection of FA is crucial. Here, we report poly (3, 4-ethylenedioxythiophene) (PEDOT) and cadmium oxide (CdO) (PEDOT-CdO) composite for the effective sensing of FA. The PEDOT nanospheres were prepared by the wet chemical method, and CdO nanorods were synthesized using the hydrothermal technique. The sulfur groups in PEDOT connected with Cd2+ ions in CdO nanoparticles enriched their electrostatic interaction developing a robust and straightforward electrochemical FA sensor. The as-prepared PEDOT-CdO biosensor exhibited good electrocatalytic activity towards selective determination of FA in the linear range of 40 nM-1 mM with a lower detection limit of 8.4 nM. In addition, the investigation of cytotoxic nature against human breast cancer cell lines (MCF-7) reveals that, the reported composite induces apoptotic cell death and can be used as an anticancer agent. The proposed biosensor can be used for device fabrication in sensor applications as well as a vector for targeted drug delivery for cancer cell diagnosis.

“…Whereas, the orientation (111) is more prominent with strong, sharp intensity and the higher value it has compared to other peaks because the film surface density energy for this direction is less than the energies of other crystal directions.

“…It is considered one of the most promising semiconductors oxides in the development of photovoltaic devices, especially in photovoltaic diodes, solar cells and gas sensors, with other important applications being manufactured from cadmium oxide films. [1,2,3] Cadmium oxide thin films have been prepared on a large scale using several of the techniques, such as: solid-vapor [4], successive ionic layer adsorption and reaction (SILAR) [5], sol gel [6], chemical bath deposition (CBD) [7], spray pyrolysis [8], layer adsorption [9], sputtering [10] and mechanochemical [11]. Thermal vacuum technology is one of the important methods for preparing the membrane because it has good sedimentation properties, the most important are: (i) the good adhesion for the films with substrate, (ii) the deposition of multiple and very thin layers for different the materials [2].…”

This investigation reports the effect of the addition of CdO nanoparticles on the (Bi,Pb)-2212 superconducting phase. The superconducting samples of general formula (CdO)x Bi1.6 Pb0.4 Sr1.9 Ca1.1Cu2.1 O8 (x = 0.00, 0.01, 0.02, 0.05, and 0.1 wt%) are synthesized using the conventional solid-state reaction technique. Powder X ray diffraction analysis confirms the formation of a single-phase orthorhombic Bi-2212. The variations in the lattice parameters are explained based on the Jahn Teller distortion induced by the increase in the oxygen content owing to the addition of the CdO nanoparticles. The increase in the oxygen content is confirmed via Idiometric titration analysis. The grain morphology is investigated using scanning electron microscopy (SEM). The effect of CdO addition in enhancing grains connectivity by the filing of pores and voids is revealed. Fourier transform infrared (FTIR) spectroscopy is conducted to analyze the functional groups, based on the effect of calcination temperature and CdO addition. Dc-electrical resistivity measurements and I-V characteristics show an enhancement of the superconducting transition temperature (Tc) and the critical current density (Jc) with CdO addition up to x=0.05 wt%, followed by a further decrease. By analyzing the results of the X-ray photoelectron spectroscopy (XPS), the variations of the superconducting properties are explained based on the preferred substitution of Pb2+ ions in the Bi3+ or Cu2+ sites induced by the variations in the oxygen content generated by the addition of CdO nanoparticles.
