A solubility model for Merocyanine-540 dye together with the interface’s electron transfer kinetics of MC-540/TiO2 has been investigated(Merocyanine 540-based dye has been used effectively in dye-sensitized solar cells).The highest absorption peaks were recorded at 489 nm and 493 nm in Water and Ethanol solvent,*** vacuum phase which yielded 495 nm(associated with a modest electron injection-free energy value(Ginj)of−2.34 eV for both Water and Ethanol solvents).The time-dependent density functional theory(TD-DFT)method approach has been applied in this ***,the electronic structure and simulated UV-Vis spectra of the dye in different solvents have been determined,and the alignment with the solar spectrum has been discussed to a certain *** energy level diagrams and electron density of the primary molecular orbitals are shown,and the major issues that have an impact on our new interface’s performance are *** is concluded that the proposed Solvation Model(SM)can improve the performance of Dye-Sensitized Solar Cells.

The Mediterranean Sea is home to an interesting biodiversity. The current cumulative and descriptive study aims to enumerate some relatively large marine mammals, reptiles, and fishes that have been spotted, caught, by-caught, or stranded on the coast of the Gaza Strip, Palestine, which extends about 42 km along the Mediterranean Sea. This 20-year study from 2003 to 2022 relied much on frequent field visits, meetings, and discussions with stakeholders, following local media sites and social media pages, and photography. The study recorded at least 26 giants or relatively large marine organisms on the Mediterranean coast of the Gaza Strip, Palestine. Certainly, the coming years may bring other marine organisms of relatively large sizes. Marine mammals included three species of cetaceans with the Fin Whale (Balaenoptera physalus) being the largest mammal and even the largest animal ever recorded in this study. Marine reptiles included three species of sea turtles, the largest of which is the Leatherback Sea Turtle (Dermochelys coriacea), which is in fact the world’s largest sea turtle. The bony fishes were represented by ten species, the largest of which was the Ocean Sunfish (Mola mola), which is the largest bony fish in the world. The cartilaginous fishes included ten species with the largest specimens encountered were the Shortfin Shark (Isurus oxyrinchus), Bluntnose Sixgill Shark (Hexanchus griseus), Scalloped Hammerhead Shark (Sphyrna lewini), and Giant Devil Ray (Mobula mobular). Seabirds were not included in the study. The Alexandria Pompano (Alectis alexandrinus) and the Silver-Cheeked Toadfish (Lagocephalus sceleratus), which are bony fishes, appear to be the relatively smallest marine organisms recorded here. In conclusion, the role of the various parties must be coordinated to ensure the sustainability of human activities and their compatibility with the task of conserving local marine biota, including the gigantic or relatively large ones.
