“…It is mainly categorized according to the required output characteristics which divided into three types: Smaller-the-Better, Larger-the-Better, or Nominal-the-Better. [27][28][29] Corrosion current (I corr ) should follow Smaller-the-Better characteristics, since lower I corr value is mean to obtain a better corrosion resistance coating on low Sncoated steel. Meanwhile, analysis of variance (ANOVA) and regression analysis were also conducted.…”

In this work, the tinplate with 0.5 g·m−2 tin coating mass was prepared in order to improve the economic benefit for food packaging field. We studied this low Sn-coated steel surface state and developed a process combined Mo-Mn-Al-P coating based on its special structure. By Taguchi techniques optimization, this chromium-free multi-elements coating has excellent corrosion resistance and adhesion with organic coatings, would be a hopefully replacing traditional chromate passivation treatment on tinplate with low tin coating mass.

“…The results of the ANOVA analysis for the Hardness show that the max force(µN)is an important factor in the process, with a contribution of 46%, followed by the reinforcement content (g) with a contribution of 38%, and max depth (nm ) with (13%) but considered max stiffness not significantly factor with contribution (3%) illustrated that in Table 7. These results show that the mechanical properties or hardness are more influenced by the max force (µN) and reinforcement content (g) [27], therefore, there can be negligible max depth (nm) max stiffness from the model because no significant factor, the model becameas Equation ( 2 (2)…”

Bio-composite materials were fabricated for wound healing in three concentrations.• Biodegradable polymers were used to create electrospun fibers. • A blend of polyvinyl alcohol and chitosan, incorporated with nanoparticles, was used to modify mechanical properties.This study uses electro-spinning techniques to create a poly(vinyl alcohol)chitosan-zinc oxide nanoparticles (PVA+CS)+ZnO NPs system in three concentrations of ZnO for application as composite nanofibers for wound treatment applications and Employing the Taguchi technique to optimize the mechanical characteristics via a four-level experimental design process (L16).Numerous techniques have been utilized to characterize the nanofibrous scaffolds: contact angle measurement, cytotoxicity testing, proliferation testing, evaluation of antimicrobial activity, Fourier Transform Infrared Spectroscopy (FTIR), Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersion X-ray Spectroscopy (EDX), and a comparative experimental study involving the determination of hardness using the Nanoindentation method for (PVA+CS)+ZnO. The ideal combination for adding ZnO as nanoparticles was found to be (PVA+CS)+0.6 ZnO, with a flow rate of 0.5 mL/hr, an applied voltage of 18 kV, and a needle tip-to-collector distance of 15 cm (position). This resulted in the smallest fiber diameter (48 nm) with a smooth and uniform distribution. As a consequence, (PVA+CS)+ZnO can be regarded as non-toxic in accordance with the criteria. The methyl thiazole tetrazolium (MTT) assay was used to evaluate the cell viability of L929 (cell cultures for skin). It significantly affects cell viability, achieving 50% in less than 24 hours, which means cell growth through 24 hours is necessary for embryonic development, tissue repair, and regulation of cell division in case of wound healing. Exhibiting findings of inhibition zone diameter in antibacterial activity test exceeding 20 mm. According to the results, (PVA+CS)+0.6 ZnO's hydrophilic properties showed a well-connected porous structure and made it easier for nutrients and oxygen to be exchanged, encouraging cellular activity. After evaluating the mechanical characteristics of each specimen, the main determinants of these characteristics are determined using a Taguchi orthogonal array L16 design. The results of this study suggest that (PVA+CS)+0.6 ZnO could be a good biomedical material for skin tissue engineering applications.

Line-Edge Roughness from Extreme Ultraviolet Lithography to Fin-Field-Effect-Transistor: Computational Study

Although extreme ultraviolet lithography (EUVL) has potential to enable 5-nm half-pitch resolution in semiconductor manufacturing, it faces a number of persistent challenges. Line-edge roughness (LER) is one of critical issues that significantly affect critical dimension (CD) and device performance because LER does not scale along with feature size. For LER creation and impacts, better understanding of EUVL process mechanism and LER impacts on fin-field-effect-transistors (FinFETs) performance is important for the development of new resist materials and transistor structure. In this paper, for causes of LER, a modeling of EUVL processes with 5-nm pattern performance was introduced using Monte Carlo method by describing the stochastic fluctuation of exposure due to photon-shot noise and resist blur. LER impacts on FinFET performance were investigated using a compact device method. Electric potential and drain current with fin-width roughness (FWR) based on LER and line-width roughness (LWR) were fluctuated regularly and quantized as performance degradation of FinFETs.
