Shape Memory Alloys (SMA) are widely utilized in numerous industrial applications nowadays. Significant attention has been given to Fe-based SMA in civil engineering applications due to their high strength and reasonable cost. Researchers are striving to improve the corrosion resistance of these alloys so they can be utilized in marine environments. This article focuses on the effect of Gd, V, and Y alloying on FeMnNiAl based SMA. The phases and morphological effects were characterized using X-Ray diffractometer (XRD), Scanning Electron Microscopy (SEM), and Energy Dispersive Spectroscopy (EDS). To examine the corrosive nature of the Fe-based SMA system, a potentiodynamic analysis and electrochemical impedance spectroscopy (EIS) tests were performed in 3.5% NaCl solution. Results show that the addition of Gd rare earth metal has improved the overall corrosion efficiency of Fe-based SMAs by 48%. © Published under licence by IOP Publishing Ltd.

The objective of this work is to assess the effectiveness of incorporating most commonly used glycerol based green solvent for the separation of an azeotropic mixture of interest in bio-diesel and chemical industry. To evaluate the viability of this application, the phase equilibrium for the ternary system (n-hexane + ethanol + deep eutectic solvent (DES)) was experimentally determined with vapor composition, activity coefficient and pressure using head space gas chromatography method. Within a wide range of DES concentrations, experimental vapor–liquid equilibrium data for binary system: n-hexane and ethanol with DES consisting of choline chloride and glycerol are recorded are reported at 328.15 K. The Non-Random Two-Liquid (NRTL) activity coefficient liquid model is applied to correlate its phase behavior. The machine learning algorithms for support vector machines and Gaussian process regression are used for correlation and is found to be satisfactory in binary system. Using machine learning surrogates, the coefficients required in NRTL can be avoided which requires large computational efforts, and thus can be employed for wide range of mixtures. © 2025 Elsevier B.V.

The majority of Ethiopia's population, primarily women, is susceptible to smoke inhalation during cooking, and they spend the majority of their time striving to collect firewood. Biomass deforestation for cooking harms the rural household economy and contributes to national and global environmental change, such as pollution and health issues. The effort should aim to integrate the Scheffler concentrator with a thermal storage system via the secondary solar cooking reflector in order to stimulate indoor cooking while avoiding concerns associated by carbon inhalation and deforestation. As a result, the Injera bakery system powered by solar thermal energy is born. There is a primary (Scheffler), secondary (reflective), and thermal storage device incorporated, as well as a cooking (pan) mounts. Solid works software was utilized for Scheffler focus and secondary reflector modeling and simulation. The thermal retention capacity of a storage device is determined using heating and cooling curves generated by software modeling and simulation. The findings gained would aid in the development of any comfortable indoor cooking system specifically for rural areas without a grid connection, and as a result of this study, carbon inhalation and deforestation difficulties would be mitigated. Through automation, the output rate would also increase the amount and efficiency of injera. This analysis focuses on the Injera baker concept for domestic applications. © 2021

In this paper, we develop a novel approach to achieve ultra-high resolution in organic light-emitting diodes (OLEDs) through a photolithography patterning process. It is important to apply a solvent resistant electron transport layer (ETL) in the photolithography pattering of OLED because of solution coating process of photoresist on the ETL. Therefore, a solvent resistant ETL named 2,7-bis(4,6-diphenyl-1,3,5-triazin-2-yl)-9,9′-spirobi[fluorene] (SBF-Trz) was developed and employed as the ETL of OLEDs. The SBF-Trz demonstrated excellent solvent resistance during photolithography process and enabled device performances comparable to those of the conventional OLED without any photolithography process. It was found that the SBF-Trz ETL is appropriate as the ETL of the OLED patterned by photolithography due to good electron transport property, good stability, and good solvent resistance. © 2024, John Wiley and Sons Inc.
