“…After performing the experiments, the output variables were analysed to extract independently the main effects of the input factors. So, statistical analysis such as the analysis of mean (ANOM) and the analysis of variance (ANOVA) were performed to find the optimum levels of each controlling factor and to estimate how much the variance in lithium uptake is due to control factors or experiment error, respectively, [25, 26]. Furthermore, the percentage contribution of each factor was determined by this method [27].…”

Recent study has shown that the spinel type of MnO 2 nanoparticles have a required capacity for lithium extraction from liquid resources. The low lithium adsorption capacity of synthesised ion sieves was found to be an important limiting parameter for their use in industrial applications. Therefore, increasing the uptake capacity of different ion sieves by studying the effect of six effective parameters, involving lithium salt compound, manganese salt compound, oxidising reagent, calcination temperature, heating time and Li/Mn mol ratio, on the synthesised ion sieves was investigated. Hence, in this reported work, a specific approach based on the L 9 (3 4) Taguchi orthogonal array was employed to evaluate these parameters and to optimise them in two separate stages. Also, the relative importance of each factor was determined using analysis of variance. Although, all mentioned parameters had a significant effect on lithium uptake capacity, the oxidising reagent and the lithium salt compound were the most effective factors. Also, an appropriate ion sieve with a lithium adsorption capacity of more than 9 mmol g −1 was synthesised for the first time.

“…The Taguchi orthogonal arrays of L 9 (3 4 ) were employed for this study, which can be observed in Table 2. The effect of each control factor at a given level can be estimated using the analysis of the mean and then the optimum levels of control factors for the nanostructure lithium ion sieves with better yield can be obtained [14, 15]. A statistical variance analysis (ANOVA) was performed to determine the effective parameters and their confidence levels.…”

The low lithium adsorption capacity of different ion sieves was found to be an important limiting parameter for their use in industrial extraction. The maximum exchange capacity of 6.6 mmol/g obtained till now is not high enough for their economical industrial application. Therefore, an increase in lithium adsorption capacity by studying the effects of three parameters, involving manganese salt compound, lithium salt compound and Li/Mn mole ratio on synthesised ion sieves was investigated. Moreover, the ion sieves capability on the lithium uptake from lithium-enriched solution was examined by the Taguchi experimental design method by L9 orthogonal array. Continuously, optimum conditions were predicted and confirmed by the experimental results. Based on the results, all mentioned parameters have significant effect on lithium uptake capacity, but lithium salt compound is the most effective factor. Finally, an appropriate ion sieve with lithium adsorption capacity >8.5 mmol/g was synthesised by applying the optimised conditions.

“…The three experimental parameters and their corresponding levels are shown in Table 1. A template of the 9 (3 4 ) orthogonal array, as given in Liu et al [20], was selected for study with the Taguchi method, as shown in Table 2. As seen here, there were in total nine experiments needed for this work.…”

“…It has been shown that efficient analyses of productquality characteristics can be achieved using a statistical experimental design method, that is, the Taguchi method, which is a combination of mathematical and statistical techniques used in an empirical study [20][21][22][23]. This method has been adopted to optimize various growth parameters and PDA for the ZAZ multilayers due to its potential advantages of experimental efficiency and reproducibility.…”

ZnO/Ag/ZnO (ZAZ) and ZnO/Cu/ZnO (ZCZ) were prepared. The dependence of crystalline, electrical, and optical properties for the multilayer on the postdeposition annealing (PDA) was studied. After PDA of 300°C for 20 min, the diffusion of Cu in ZnO occurs; this result is responsible for the increasing resistance of the annealed ZCZ. Ag with a thickness of 10 nm was deposited upon ZnO. The interface of ZnO and Ag is clearly revealed by high resolution transmission electron microscopy. The crystalline of ZnO and Ag films in the ZAZ with a sheet resistance (Rs) down to 4.17 Ω/sq. The ZAZ layer shows a better thermal stability (up to 400°C) than that of the ZCZ ones. The PDA degraded slightly the optical transmittance and increases the conductivity of ZAZ layer. The figure of merit (FOM) is applied to analysis of the ZAZ layer. The PDA can enhance the FOM of the ZAZ with Ag thickness >8 nm. The resultingRsand the transmittance ZAZ layers were analyzed by the Taguchi method to obtain the appropriate parameters. The optimized ZAZ has been verified with aRsof 2.3 Ω/sq, a high transmittance (71%), and the optimal FOM of 1.41 × 10−2 Ω−1.
