“…Where I i and I t are the intensity of the incident and transmitted light, respectively; A is the absorbance; and d is the film thickness. Figure shows the absorption coefficient spectra of different concentrations of CdSe/ZnS/PVC nanocomposites in which an absorption band at λ ≈ 280 nm is observed, which is assigned to π–π* transition as a promotion of electrons from pi bonding orbital to pi anti‐bonding orbital of pure PVC . In addition, the intensity of this absorption band has increased and has a blue shift at λ ≈ 272 ± 7 nm as the concentration of CdSe/ZnS increases.…”

It is valuable to understand the way the wettability is affected by the solid and the liquid surface free energies. For this study, transparent films of CdSe/ZnS/PVC nanocomposites have been prepared and characterized by FTIR and contact angle measurements. Moreover, the presence of polar interactions at the liquid/polymer interfaces, which show a proportionality to the polar components of the liquid surface energy for pure polyvinyl chloride (PVC) and all CdSe/ZnS/PVC nanocomposites, is also studied. By using the surface polarizability hypothesis, there is possibility to obtain the dispersion component of surface‐free energies of pure PVC and also its nanocomposites from the contact angles measurement of only polar liquids. This approximately is coincident with that published data for pure PVC obtained from both polar and nonpolar liquids' contact angles. In addition to this, the absorption spectra and the photoluminescence illustrate clearly the effect of CdSe/ZnS quantum dots on their host matrix. The calculated values of the optical parameters, such as energy gap and Urbach energy, illustrate an inverse proportionality between them. POLYM.

“…Nanoparticles (NPs) are materials ranging in size from 1–100 nm, with unique properties compared to bulk materials [ 1 ]. Their higher surface-area-to-volume ratio is a very important unique property that allows them to be used in different fields of chemical, food, electronic, and healthcare industries [ 2 , 3 , 4 ]. There are various physical, chemical, and biological approaches to synthesizing NPs ( Figure 1 ).…”

Plants are rich in phytoconstituent biomolecules that served as a good source of medicine. More recently, they have been employed in synthesizing metal/metal oxide nanoparticles (NPs) due to their capping and reducing properties. This green synthesis approach is environmentally friendly and allows the production of the desired NPs in different sizes and shapes by manipulating parameters during the synthesis process. The most commonly used metals and oxides are gold (Au), silver (Ag), and copper (Cu). Among these, Cu is a relatively low-cost metal that is more cost-effective than Au and Ag. In this review, we present an overview and current update of plant-mediated Cu/copper oxide (CuO) NPs, including their synthesis, medicinal applications, and mechanisms. Furthermore, the toxic effects of these NPs and their efficacy compared to commercial NPs are reviewed. This review provides an insight into the potential of developing plant-based Cu/CuO NPs as a therapeutic agent for various diseases in the future.

“…The spectra consist of spikes with different inclination for different composition of lithium iodide (LiI). Normally, the spike at higher frequencies can be attributed to grain boundary effect while the semicircle arc at lower frequencies was probably caused by the resistance within the bulk/grain of the studied material [5,6]. The grain boundaries act as barriers towards mobile ions.…”

Low ionic conductivity and easily attacked by air are among the common issues of lithium salts in lithium based solid electrolytes. Toward this end, our efforts have been focused on the development of a new lithium based electrolyte system which exhibits a good stability against atmosphere and posses high electrical conductivity. Normally, lithium carbonate (Li2CO3) alone shows a low electrical conductivity (2×10-5 Scm-1). However, the corporation of lithium iodide (LiI) has made a significant impact on the electrical conductivity of the system (4.63×10-3 Scm-1). The xLi2CO3-yLiI (x = 95-70, y = 5-30 wt.%) solid electrolyte were prepared by mechanical milling technique. The electrical and structural properties of the electrolyte systems were characterized by Electrical Impedance Spectroscopy (EIS) and Fourier Transform Infrared (FTIR) respectively. The highest electrical conductivity (4.6×10-3 Scm-1) of the electrolyte system was obtained from the sample containing 20 wt.% of lithium iodide (LiI). The carbonate groups play a role to provide sites for the interaction between interconnected pathways and lithium ions for the fast lithium ion migration.
