Tailoring the bandgap of a material is necessary for improving its optical properties. Here, the optical bandgap of high-entropy oxide Ce0.2Gd0.2Sm0.2Y0.2Zr0.2O2-δ (HEO) nanoparticles was modified using Pr3+. Various concentrations of Pr3+ (x = 0, 0.01, 0.02, 0.05, 0.075, 0.1, 0.15) were incorporated into the host high-entropy oxide using a gel combustion synthesis. After the gel combustion step, the powders were heat-treated at various temperatures (650 °C, 800 °C, 950 °C) for 2 h. The obtained Pr3+-incorporated HEO powders were characterized using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and UV–visible spectroscopy. The results indicate that, when the samples are calcined at 950 °C, a single-phase cubic fluorite structure is obtained without any phase separation or impurity. The optical absorbance red-shifts to higher wavelengths when the concentration of Pr3+ is increased. This reduces the bandgap of the material from 3.15 eV to 1.87 eV for Pr3+ concentrations of x = 0 (HEO-0) and x = 0.15 (HEO-6), respectively. The obtained HEOs can be suitable candidates for photocatalytic applications due to their absorbance in the visible region.

Abstract In the recent years, the using of fossil energy source-based fuels are delivering to the predetermined nature, health and environmental exposure, there is a universal necessitate prepared to well improvement and consumption of renewable energy source and apparatus. With the rapid growth of human life, energy is more essential. The explosive growth of population and energy consumption demands are the exclusive issue of the present world. In response to the energy demands, the growth of highly efficient energy conversion and storage devices. With increasing energy demands and environmental pollution, there is a requirement of the world to great some novel conducting materials consist of Perovskite solar cells (PSCs) which is delivered that excellent photoconversion efficiencies (PCE) compare with the other silicon supported photovoltaics, and also semiconducting materials for the conversion of substitute energy sources and preparation of high high-performance semiconductor devices. Semiconducting thin films play an indispensable role in fashionable science and electronic technology. Among them, the II–VI compound semiconductor thin films are an important class of materials, and they are generally comprehensive wide-band gap materials. In addition, the un-doped and rare-earth metal ions doped zinc selenide (ZnSe) thin films are currently the most demanding and technologically important materials, which have the potential for optoelectronic devices (solar cells, photoelectrochemical cell and light emitting diodes) and are active throughout the entire visible spectrum extending into the infrared wavelengths. Various techniques for depositing thin coatings on these substances are utilized to a greater extent. In this review, the most recent advanced techniques in the application of semiconducting materials-based thin films were produced in various energy-generated fields, particularly solar cells, with a major focus on a review of recent progress in the development of various types of ZnSe thin film-based material for high-performance semiconducting thin film material for solar cell application. Lastly, the advantages and material challenges of semiconductor-based thin films for future sanitary energy device process are described.

Abstract Adsorption is vital for the elimination of Cr6+ and Pb2+ ions in the contaminated solution medium. A ternary blend made up of chitosan, nylon 6 and polyurethane foam (CS/Ny 6/PUF) blend in the ratio of 2:1:1 has been investigated. These blends are used as an adsorbent due to the insoluble nature in acidic and basic medium. The adsorption efficacy was analyzed by modifying pH, contact time, and adsorbent dosage. The maximum uptake of metal ions has been exhibited in the pH range 5. An equilibrium adsorption statistic indicated that adsorption isotherm follows the Freundlich model. The adsorption kinetic parameters specified that the adsorption of chromium has shown pseudo-second-order and lead pseudo-first-order reaction.

Composite materials very often provide new catalytic, optical or other physicochemical properties not observed for each component separately. Photofunctions in hybrid systems are an interesting topic of great importance for industry. This review presents the recent advances, trends and possible applications of photofunctions of hybrid systems composed of Schiff base metal complexes and metal or semiconductor (nano)materials. We focus on photocatalysis, sensitization in solar cells (DSSC—dye sensitized solar cell), ligand-induced chirality and applications in environmental protection for Cr(VI) to Cr(III) reduction, in cosmetology as sunscreens, in real-time visualization of cellular processes, in bio-labeling, and in light activated prodrug applications.

Abstract In this study, the gold nanoparticles loaded indole-3-acetic acid (IAA) based nanocomposite hydrogels have been prepared using ethylene glycol (EG) and citric acid (CA) by condensation polymerization without crosslinking agent. Two different concentrations of nanocomposite hydrogels have prepared and named as ICE-Au-1 and ICE-Au-2. Moreover, the resulting nanocomposite hydrogels were confirmed by FT-IR, UV and SEM analysis. The TEM and EDX system were used to found the shape and composition of gold nanoparticles in prepared nanocomposite hydrogels. The variation of swelling have noticed in acidic pH than the alkaline medium due to binding of gold nanoparticles. The results of biological properties such as antimicrobial, antioxidant and biocompatible studies were also critically discussed. Thus, the aim of this work was to study various composition of gold nanocomposite hydrogels and its relation with stoichiometric concentration of monomers to evaluate good biomedical material in mere future.

ABSTRACT In this study, attention has been paid to synthesize and investigate pH-sensitive biopolymeric hydrogel from renewable resource-based monomers such as citric acid, pyrrole-2-carboxylic acid, and ethylenediamine through two-step condensation polymerization. The formation of hydrogel and structure of hydrogel were confirmed by Fourier-transform spectroscopy and nuclear magnetic resonance spectroscopy (1H-NMR and 13C-NMR) analyses. Thermal stability and glass transition temperature of hydrogel were analyzed by thermogravimetric analysis and differential scanning calorimetry analysis. Swelling studies of the hydrogel at various pH media ranging from 3.0 to 10.0 have also investigated. The swelling behavior of hydrogel increased in acidic media than in basic media. Scanning electron microscopic analysis revealed the spherical shape and porous nature of the hydrogel. The antibacterial activity of hydrogel was investigated against gram-positive (Staphylococcus aureus) and gram-negative (Escherichia coli) bacterial species at different concentrations. The cytotoxicity study of the hydrogel has been carried out using MTT assay method. Hence, the biopolymeric hydrogel with smart pH sensitivity may be considered an excellent candidate for industrial, environmental, and biological applications. GRAPHICAL ABSTRACT
