Influence of ultrasonication time on solar light irradiated photocatalytic dye degradability and antibacterial activity of Pb doped ZnO nanocomposites

Porous Pb-Doped ZnO Nanobelts with Enriched Oxygen Vacancies: Preparation and Their Chemiresistive Sensing Performance

“…By increasing the doped amount of Pb, the position of the (100) diffraction peaks shifted to lower angles. This phenomenon confirms that the Pb element, identified as Pb 2+ by the following XPS analysis, was indeed incorporated into the ZnO lattice and occupied the hexagonal Zn 2+ cation site [17]. Further lattice refinement of the XRD data displayed in Table S1 revealed the detailed change of their crystal lattices.…”

Alginate-based hydrogels embedded with ZnO nanoparticles as highly responsive colorimetric oxygen indicators

“…Crystallite sizes of ZnO nanoparticles were calculated by evaluating the full width half maximum (FWHM) of the peak for the highest intensity peak ( β 101 ) using Debye–Scherrer's formula. 48 eqn (1): D 101 = Kλ /( β 101 cos θ )where D 101 is the crystallite size of ZnO based on the (101) plane, K (0.9) is a constant, θ is Bragg's diffraction angle and λ is the wavelength of X-rays used (1.54 Å).…”

“…The ultrasonication obviously affects the characteristics of the ZnO nanoparticles, such as the reduction of the crystallite size and particle size of the nanoparticles with increasing ultrasonic time. 48,56 Swelling behavior of the hydrogels In realistic conditions, the environmental relative humidity (RH) influences the moisture content in the hydrogel. When a hydrogel is kept at low RH, it will lose water to balance its moisture content.…”

Microwave-assisted synthesis of Ag/ZnO nanoparticles usingAverrhoa carambolafruit extract as the reducing agent and their application in cotton fabrics with antibacterial and UV-protection properties

“…18 ZnO nanoparticles are generally synthesized using various chemical and physical processes, such as microwave-assisted method, hydrothermal method, co-precipitation, electrochemical technique, ultrasonic approach, and sol-gel procedures. [19][20][21][22][23][24] However, most of these processes involve the use of toxic chemicals and solvents that prove to be detrimental to both human health and the environment. Microwave-assisted synthesis of ZnO nanoparticles is a promising technique for fabricating nanostructures within a controlled environment reliably, less energy consumption and cost-effectively.…”
