“…In recent years, with the wide application and popularization of IoT access devices, as well as the rapid development of mobile data networks, the 5G (The 5th Generation Mobile Communication) era of Internet of Everything has provided a good environmental foundation [1]. At the same time, in order to cater to the rapidly developing mobile Internet of Things information technology, the 5G communication era needs to carry larger data services, making the information transmission between "people" and "things," "things," and "things" more smooth and convenient [2].…”

In order to address the dissipation of energy efficiency in 5G edge computing, and the problem of network delay, better improve the quality of user service, considering the data aggregation delay while improving the network energy efficiency. The author proposes a 5G edge computing access node selection algorithm based on energy efficiency and delay; through the energy efficiency and delay balanced data collection mechanism (EEDBDG), a new dynamic tree is used to organize the network topology, eliminating the hot zone problem; nodes dynamically choose routes and take turns acting as the root of the tree, which collects data and communicates directly with the base station. At the same time, three data collection strategies are proposed for different latency and energy efficiency requirements: delay optimal algorithm (EEDBDG-D), energy efficiency optimal algorithm (EEDBDG-E), and energy efficiency delay balance algorithm (EEDBDG-M). Experimental results show that, when the communication radius of nodes is limited, EEDBDG balances the energy consumption of nodes, prolongs the network life time, and shows outstanding performance in energy saving and time saving. Compared with GSEN, in the best case, the network lifetime of EEDBDG-E is increased by 72%, and the convergence delay of EEDBDG-D is reduced by 74%. Conclusion. The algorithm can effectively reduce the energy dissipation and delay of edge computing.

“…Pentacene was produced as a pure solution by dissolving (0.01 g in 10 ml) of chloroform. As well as to the solution of Pentacene doped with dye, the same weight of dye was added, 0.01 g+0.01 g in 10 ml of chloroform and placed in an airtight glass container and placed on the magnetic stirrer for 3 hours, then left for 24 hours to ensure complete dissolution, after which the solution was filtered and the molar ratio was calculated according to the following law [9]:…”

“…Pentacene is a polycyclic aromatic hydrocarbon composed of five benzene rings connected linearly and conjugate, belongs to the acnes group; It is an organic semiconductor that is blue/black in hue, strength of the dye-doped pentacene films was investigated. The electrical characteristics of pentacene and its potential usage in transistors were studied [9,10]. Doping also increased the conductivity properties of pentacene [11].…”

This investigation explores the impact of natural dye extract from the Lanata Kamra plant on the electrical conductivity of pentacene (PE) polymer thin films. Films of pure PE were spin-coated with a 1:1 dye ratio, and their characteristics were examined using Xray diffraction. The results highlighted the presence of a dominant PE peak in the 22th-28th range, a grain size of 0.341 nm for the pure PE, and 0.491 nm for the dye-doped polymer. The uniformity of the membrane surfaces suggested a regular arrangement of polymer units. The morphology of the films was further investigated with Scanning Electron Microscopy (SEM) at 200 nm and 500 nm resolutions, revealing the formation of surface fractures due to polymer shrinkage during production. The SEM analysis also indicated strong inter-chain interactions during membrane formation, resulting in spherically shaped crystals. Electrical properties, including current-voltage characteristics, were assessed using a Keithley Series 2400 source meter, operating within a voltage range of 1-100 V and a temperature of 30℃. The results demonstrated an increase in electrical conductivity with increased dye doping. Optical properties were examined over a wavelength range of 300-780 nm, suggesting the potential applicability of this model to photosensitization processes.

This work is devoted to the influence of magnetized water on dye extracted from Anchusa Italica plant and doped pentacene thin films. The findings resulted in optoelectronic behavior, showing that using magnetized water in the extraction process gives rise to distinct and superior characteristics as compared to using regular water. The Fourier-transform infrared method was used to analyze the structural properties of an Anchusa Italica-doped pentacene thin film. A comparative study on two samples was carried out: the first sample was affected by a static magnetic field and the other one was not. Optical properties including the absorption spectra absorption coefficient, optical energy gap, conventional and refractive factors were investigated by applying ultraviolet-visible spectroscopy ranging from 300 to 900 nm. The estimated band gap edge of the dye/doped pentacene affected with magnetization was reduced from 2.61 to 1.76 eV and converted into the recommended direct band gap to contribute to optical systems. The absorption spectra of the sample with magnetization effect appears to be more efficient than the one extracted using regular water. The power transmission coefficients (indirect to direct) were also affected because of the magnetic extraction procedure. The complex refractive index was used to study the magnetization effect on the resonance mode and transparent indicator. The absorption index was enhanced to 570 nm in the spectrum, whereas there was also a low attenuation coefficient. This is the first time that magnetized sol has been used in dye extraction processes.
