Characterization of multifunctional solution-processed Sn1-xZnxS nanostructured thin films for photosensitivity and photocatalytic applications

Ameliorated Li+ extraction/insertion kinetics and stability of LiMnPO4 by Al3+ doping

“…It can be seen that Li 0.98 Al 0.02 MnPO 4 /C shows a quicker current decay than LiMnPO 4 /C, indicating that the rate of Li + insertion during discharge is higher for Li 0.98 Al 0.02 MnPO 4 /C. According to the previous literature, 61–70 it is known that parameters such as particle size, crystallite size and micro-strain would highly affect the physical properties of materials. In olivine cathode materials, Chiang et al 50,51 showed that the two-phase transition kinetics depends heavily on the particle size.…”

Quantitative prediction of ternary mixed gases based on an SnO2 sensor array and an SSA-BP neural network model

“…3(a) shows the SEM image of the SnO 2 material synthesized by the bio-template method, in which the popcorn-like micro elliptical structure could be observed. 33–35 Furthermore, Fig. 3(b) indicates that the average longer diameter is approximately 0.243 μm.…”

Lutetium-Doped ZnO to Improve Photovoltaic Performance: A First-Principles Study

“…In the ideal situation, transmittivity can be defined as (10) where d is the film thickness, which is ideally 1 nm.…”

“…However, these properties of ZnO are unstable due to oxygen adsorption, which leads to pure ZnO being a poorly n-type semiconductor with low electrical conductivity . Therefore, to increase its conductivity while maintaining its original optical properties, a large number of researchers have used impurity doping methods such as magnetron sputtering, facile solution process, chemical vapor deposition, and sol–gel methods. , For example, Park et al doped alkali metals (Li, Na, and K) into ZnO by a novel solution-processed method and found that the electron mobility of ZnO was improved. Similarly, Mahdhi et al prepared Ca-doped ZnO by magnetron sputtering and found that ZnO has a transmission rate of more than 85% in the visible range and a lower resistivity at room temperature.…”
