“…In order to investigate the effect of different solvents on the spinnability, morphology and properties of PLA micro/nanofibers, 6% PLA solutions were dissolved in seven different solvents or solvent mixtures, respectively. Besides, it is reported that the addition of inorganic salts will be in favor of electrospinning process and can effectively eliminate the beaded fibers due to increasing the conductivity of polymer solutions [28], so CaCl 2 was added in S7 compared with S6 to study whether the morphology and properties of obtained outcome change. The specific formulation of the electrospinning solutions in this paper was listed in Tab.…”

Electrospinning is a versatile and popular method for the fabrication of ultrafine fibers and many parameters in electrospinning can be adjusted when ideal micro/nanofibers are required. In particular, the selection of a proper solvent condition is a fundamental and crucial step to produce electrospun ultrafine fibers. In this study, a commonly used biomaterial, polylactic acid (PLA), was dissolved in 7 different solvents and PLA micro/nanofibers were prepared by electrospinning. The morphology, porosity, mechanical property and static contact angle were characterized to determine the quality of the obtained product. The results show that different solvent conditions have a significant effect on both the diameter, surface smooth degree of PLA micro/nanofibers and the properties of the fibrous membranes.

“…One such solution uses a nanofluid (a stable suspension consisting of a base fluid and nano-sized solid particles dispersed in it) or fine-dispersed suspensions. The nanofluids show improved heat transfer [9][10][11][12][13][14][15][16][17] and optical properties [18][19][20][21] than traditional single-phase heat transfer fluids and demonstrate high potential for solar energy applications [20,21]. Moreover, the nanofluids and nanoparticle suspensions have found multiple applications in microelectronics [16,17,[22][23][24], nuclear power generation [25], medicine [26,27], chemical technology [28], etc.…”

In the current essay, the numerical investigation of heat transfer in an exchanger containing nanofluid with Cu nanoparticles in the presence of a new inserter is carried out. The equations governing the turbulent fluid flow have been solved utilizing single-phase models with the aid of the finite volume method in ANSYS-FLUENT software using the k-ε turbulence model for the Re number ranging from 4000 to 8000. Furthermore, the influence of Reynolds number, nanoparticle volume fraction, and geometric characteristics of turbulator on the friction factor and Nusselt number have been scrutinized. Outcomes reveal that the newly introduced inserter performs well and increases the Nusselt number by roughly 34–54 times and the friction coefficient by approximately 1.8–3.2 times compared to the smooth tube. It is also observed that a 2 % increase in the nanoparticles volume fraction has resulted in a rise in the Nusselt number by around 92 %. To attain the optimal performance of the presented turbulator, the longitudinal distance between the inserters is recommended as S/D = 5.27, for which Performance evaluation criteria values in the range of 3.01–9.23 in the Reynolds range under investigation are acquired.
