Modeling the Thermal Performance for Different Types of Solar Chimney Power Plants

Abstract

Nowadays, due to restrictions on fossil fuels, the use of renewable energies is increasing day by day. Among renewable energies, solar energy has received more attraction due to its availability in all places. Among solar energy technologies, the solar tower has been welcomed due to its high power generation of electrical energy. For accurate modeling of the studied system, each component of the system has been evaluated and modeling has been done. Therefore, in this research, solar tower modeling has been conducted to achieve high electrical energy production, and to better compare the production rate, 5 cities in Iran with different weather conditions have been considered. According to the results, it can be mentioned that the highest production power by the studied system is related to Shiraz city with an average production of 20 kW/m2, and among the cities studied, the lowest rate is related to Mashhad with a production power of 15 kW/m2.

A review: studying the effect of graphene nanoparticles on mechanical, physical and thermal properties of polylactic acid polymer

“…53 Bioplastics can be extracted from plant materials such as starch 54 or synthetic biodegradable polymers such as polylactic acid, 55 polyvinyl alcohol [56][57][58] and poly(caprolactone). In addition, the degradation of bioplastics results in the production of carbon dioxide and water as the nal product, [59][60][61] which is not harmful to the environment. Therefore, bioplastics are one of the newest materials that are classied as environmentally friendly products.…”

Application of nano-antibiotics in the diagnosis and treatment of infectious diseases

“…Standard techniques for diagnosing infectious diseases include microscopy, tissue culture, ELISA, and PCR. These techniques have high cost, limited ability to differentiate pathogens, low speed, and poor detection threshold (Xiao and Smaisim, 2022;Mourad et al, 2022;Cheng et al, 2022;Smaisim et al, 2022b;Abderrahmane et al, 2022;Tan et al, 2022;Mir et al, 2022;Ruhani et al, 2022). At present, the molecular diagnosis of diseases is concentrated on recent advances in nanotechnology.…”

Antimicrobial finishing of textiles using nanomaterials

“…Intelligent materials that respond reversibly to external stimuli. Dicotetrahydroglyceride (Hydantoin) can show intelligent antimicrobial properties by binding to cotton fibers and being activated by bleach (Mozafarifard et al, 2022;Smaisim et al, 2022a;AbdulHussein et al, 2022;Wang et al, 2022).…”
