An environment-friendly solution for indoor air purification by using renewable photocatalysts in concrete: A review

Abstract: Photocatalyst is needed for cleaner environment and a better quality of life. This fact leads an idea of more eco-compatible use of light. This approach could become an integral component of strategies to reduce indoor air pollutants through the use of photocatalysts as construction materials. In this study, we discuss the quality of indoor air, sources of pollutants in the indoor environment, and the photocatalysis process. Moreover, the different parameters and uses of different photocatalysts in concrete for indoor air purification, starting from the early research until the current research, are described, and the reaction mechanism of photocatalytic oxidation and sustainable construction by using photocatalysts are also reviewed.

A review on nanofluid: preparation, stability, thermophysical properties, heat transfer characteristics and application

Abstract: Nanofluid is a suspension of nanoparticles which is promising heat transfer fluid in the heat transfer enhancement having a plethora of applications because of its superior thermal conductivity and rheological properties. This paper points out the previous studies and recent progress in the improvement of heat transfer using nanofluid. The recent progresses on preparation and enhancement of stability were reviewed. Thermophysical, heat transfer characteristics of nanofluid and different factors such as particle size, shape, surfactant, temperature, etc. on thermal conductivity were presented. The present study reveals potential applications by utilizing nanofluid such as heat exchanger, transportation cooling, refrigeration, electronic equipment cooling, transformer oil, industrial cooling, nuclear system, machining operation, solar energy and desalination, defense, etc. Few barriers and challenges were also addressed. Finally, the challenges and further research opportunities were presented.
