“…They are produced in ambient temperature conditions. Their surface can be easily changed for selective targeting (Targeting) and these Ps particles protect the environment well.It should be noted that although biodegradable polymer nanoparticles easily release the drug, the efficiency of PDT depends on the production of 1 O2, so drug release is unnecessary (Mir et al, 2023;Abderrahmane et al, 2023;Wang et al, 2023a;Chen et al, 2023a;Narayanasamy et al, 2023). The half-life of 1 O2 in aqueous medium is in the microsecond range because 1 O2 reacts rapidly.…”

Most of the treatment strategies for tumors and other disorders is photodynamic therapy (PDT). For several years, increasing the efficiency of nanostructured treatment devices, including light therapy, has been considered in different treatment methods. Light Dynamics The use of nanomaterial in this method's production and progress. The use of nanoparticles as carriers is a promising accomplishment, since all the criteria for an ideal photodynamic therapy agent can be given with these nanomaterials. The kinds of nanoparticles that have recently been used in photodynamic therapy are mentioned in this article. Latest advancements are being explored in the use of inorganic nanoparticles and biodegradable polymer-based nanomaterial as carriers of photosynthetic agents. Photosynthetic nanoparticles, self-propagating nanoparticles, and conversion nanoparticles are among the successful photodynamic therapy nanoparticles addressed in this report.

“…Computational analysis of rectangular, stepped and elliptical pin-n pro les for space vehicle thermal control systems have been performed by M.P. Narayanasamy et al [5] and they obtained that in comparison with at pinns, elliptical pin-ns increase heat transfer by an average of 20%. The perforations in the pin-n are one form of optimization and enhancement of heat transfer rate.…”

It is a computational model analysis on symmetrical aerofoil pin-fin arrays. The commercial ANSYS 2021 R2 computational tool has been utilized. There are four models prepared on symmetrical aerofoil pin-fin arrays. These four models are no perforated inline aerofoil pin-fin array, perforated inline aerofoil array, no perforated staggered aerofoil array and perforated staggered aerofoil array. The basic geometry, meshing and computational analysis has been created in the Workbench, ICEM and Fluent Discover tool, respectively. In the Fluent solver settings, the k-omega turbulent model has been selected. The Reynolds number implied from 5,000 to 50,000 with an incremental value of 5,000. Moreover, the temperature valve input from 27 to 350℃. The results show that at rising input airflow velocity increases Nusselt number. Out of all the four models the convective heat transfer rate in the perforated one is quite higher than no perforated one. In the staggered perforated aerofoil pin-fin obviously there is more material savings. Apart from that in the no perforated staggered aerofoil pin-fin the pressure drop is lesser and better streamline pressure drop maintained. As far as overall performance is concern the perforated staggered aerofoil pin-fin arrangement gives very promising results.
