Summary: Freshwater scarcity is a growing global concern, and seawater desalination is a crucial solution to address this issue. This study focuses on vacuum solar still systems and reviews their current status to guide future research and improvement. The study highlights the design specifications, advantages, and disadvantages of various vacuum techniques used in solar still systems. It concludes that lowering the operating pressure can significantly improve system productivity and efficiency. Forced vacuum conditions are more effective than natural vacuum conditions, but the cost of freshwater produced in natural vacuum conditions is lower than that in forced vacuum conditions.

Summary: Shortage of available freshwater has become a critical issue, leading to the development of different solar stills to supply freshwater in rural areas. However, low performance has been a major drawback. In this study, a novel stepped solar still, covered by wick porous material, is designed and built. Experimental investigations were conducted to analyze the productivity, temperature, and efficiency of the stepped solar still with different porous material thicknesses. Results showed that a thicker porous medium led to higher freshwater productivity and efficiency, and the presence of porous material affected the temperature of the internal space. The optimal porous medium was found to be 12 mm thick, with a productivity of one liter and thermal and exergy efficiencies of 24.71% and 3.528%.

Summary: Recently, reinforced polymeric composites made from natural fibers have attracted significant attention due to their sustainability, environmental friendliness, and low cost. However, the hydrophilic nature of these composites hinders their successful applications. In this study, teff straw, a crop residual material specific to Ethiopia, was used as a fiber material. The bonding strength between the fiber and polymer was improved to suppress water absorption. Mathematical modeling and kinetic behavior analysis were performed to understand the water absorption properties of the composites. A response surface-based statistical modeling was also conducted to analyze the correlation between water absorption, fiber loading, and time.

Summary: Fused deposition modelling (FDM) is a widely used additive manufacturing technique in the industry, but it often results in poor surface finish and delamination. Pre-processing techniques such as increasing resolution and changing layer thickness can improve surface finish, but at the cost of processing time. Post-processing techniques, including mechanical, chemical, thermal, and hybrid methods, can also be used, but they may affect the mechanical properties of printed components. This review paper focuses on three aspects: vapor polishing techniques, changes in mechanical properties before and after polishing, and the development of 3D printing of thermosets and composite materials.
