Solar batteries work on the basis of special modules - photocells that capture solar energy and convert it into electric current with the help of semiconductor devices. Photocells are a solar panel made from homogeneous monocrystalline silicon, which has not only high quality, but also high performance. A solar panel is able to work at very low temperatures, in a small number of places, and at the same time its effectiveness does not disappear. The maximum duration of its use reaches 30 years. Under terrestrial conditions, the growing of monocrystalline silicon is carried out by the Czochralski method, in which, when the seed comes into contact with the surface of the silicon melt, the atoms of which, in contact with the seed, lose energy and freeze, which leads to the growth of a silicon single crystal. Under terrestrial conditions, gravitational forces create a strong thermo gravitational unsteady convection, which leads to instability of the growth parameters of monocrystalline silicon and limits the possibility of obtaining monocrystalline silicon with a high degree of uniformity. The first results of growing monocrystalline silicon under microgravity conditions, where strong thermo gravitational unsteady convection disappears in the absence of gravity, showed the fundamental possibility of obtaining more perfect monocrystalline silicon. However, under microgravity conditions in silicon melts, new opportunities for non-gravitational convective processes appear - Marangoni convection, as well as (in the presence of residual gravity) small thermo gravitational processes with a decrease in the level of gravity, which leads to the problem of obtaining homogeneous monocrystalline crystals. The article presents the developed method for homogeneous monocrystalline silicon growing in microgravity by eliminating the arising non-gravitational convective processes by using controlled vertical vibration in a pre-calculated mode of the vibroturbulization process for mixing the internal components of the silicon melt in the process of growing homogeneous monocrystalline silicon by the Czochralski method in microgravity. Keywords: monocrystalline silicon growth; monocrystalline silicon solar panel; Czochralski method; conditions of microgravity; vibroturbulization process.Michael Shoikhedbrod

https://journalspub.info/physics/index.php?journal=IJSSM&page=article&op=view&path%5B%5D=190
The physical properties of cholesterol (cholesteric liquid crystal) ensure the correct packaging of the phospholipid part of the membrane, which is necessary for its normal operation, affecting on the mobility of the fatty acid tails of membrane lipids: if the membrane is too rigid and there is a danger of "freezing" fatty acid chains, cholesterol causes them to liquefy, since chains in his presence become more mobile; if the membrane is too “liquid”, then cholesterol thickens it. A number of authors explain this sealing effect of cholesteric liquid crystal (cholesterol) by the fact that the cholesteric liquid crystal (cholesterol), containing in the biological membrane, due to its physical properties, reduces the slope of hydrocarbon phospholipid tails, located not perpendicular to the membrane plane, but at a certain angle. The physical properties of cholesterol thus increase the elasticity and mechanical strength of the bilayer of bipolar phospholipids of membrane cell, due to which the membrane can change its shape in response to the force applied to it. The physical properties of cholesterol control the permeability of the bipolar phospholipids bilayer of the biological cell membrane. At temperatures above the phase transition of phospholipids, cholesterol has a condensing effect (a decrease of the area, occupied by a phospholipid molecule), reduces the rate of diffusion of phospholipids in the bilayer, and reduces the permeability of the bipolar phospholipid bilayer of membrane cell by water molecules and ions. At temperatures below the phase transition of phospholipids, cholesterol increases the area, occupied by the phospholipid molecule, increases the rate of diffusion of phospholipids in the bilayer, and increases the permeability of the bipolar phospholipid bilayer of membrane cell by water molecules and ions. The article presents a theoretical description of the beneficial influence of the physical properties of a cholesteric liquid crystal (cholesterol) on the membrane of biological cells, which plays a vital role in biological cells. It will be shown how the physical properties of cholesterol or cholesteric liquid crystal, located in the membrane of a biological cell, placed in a solution of a negatively charged catholyte, sharply increase the permeability of the bipolar phospholipid bilayer of the biological membrane cell by water molecules and ions through the cholesteric liquid crystal or cholesterol into the inside of the biological cell due to in this case, an increase of the positive electrostatic potential of the outer layer of the bipolar phospholipid bilayer, which contributes to the adoption by a cholesteric liquid crystal or cholesterol of a configuration with open gaps in relation to the environment (catholyte solution of nutrient media) between its monolayers, and thereby accelerating the exchange processes between the cell and its environment, contributing to its rapid reproduction. It will also be shown that the physical properties of cholesterol or cholesteric liquid crystal, located in the membrane of a cancer cell, placed in an aqueous solution of a positively charged anolyte, prevent the penetration of water molecules and ions through cholesterol or cholesteric liquid crystal into the inside of the cancer cell by reducing the positive electrostatic potential of the external layer of the bipolar phospholipid bilayer to zero, which contributes to o the adoption by a cholesteric liquid crystal or cholesterol of a configuration with close gaps in relation to the environment (anolyte solution) between the monolayers of cholesteric liquid crystal or cholesterol in the bipolar phospholipid bilayer of the cancer cell membrane, which stops the exchange of the cancer cell with the environment, leading to its death.Michael Shoikhedbrod

https://journalspub.info/physics/index.php?journal=IJSSM&page=article&op=view&path%5B%5D=193
Clean and green electricity has been generated by hydropower is a regenerative energy source. The process that allows hydropower plants to make hydroelectricity will be explored in this academic paper. Many kinds of rural numbers around the world, including those in Nepal, India, and China, as well as more industrialized countries like the United States, now have access to emission-free power sources thanks to small hydropower projects. A small hydropower system can be able to satisfy your energy requirements in your location if hydropower plant technology is acceptable for the region at hand. The basic components of the system, the demand for licenses and water rights, and possible ways for selling any excess electricity generated by micro hydroelectric facilities will also be covered. Constructing a tiny hydroelectric plant might be good for small canals, rivers, etc.Sarthak ShakyaAnjali SrivastavaShashank Mishra

2023-07-252023-07-25822937A Comprehensive Review of Hydro Turbine Preferences: Efficiency, Cost and Environmental Impact
https://journalspub.info/physics/index.php?journal=IJSSM&page=article&op=view&path%5B%5D=194
This paper aims to examine the various types and capacities of hydroenergy systems, with a focus on the most effective turbines that can be used. It addresses the optimal turbine for a hydroelectric plant, along with a review of hydropower technologies and turbines. Hydropower, with its inherent qualities and the benefits it provides to society, the environment, and the economy, is poised to play a significant role in the future energy mix. All remote locations, areas with severe development needs, disaster-affected areas, and distant military outposts have one thing in common: they all require efficient means of generating electricity. The most effective approach to meet these needs is to use power-generating modules that tap into the nearest renewable energy sources. A hydroelectric power plant’s main goal is to create usable electricity from the kinetic and potential energy of a moving body of water. Hydropower endeavors need a range of criteria at different stages of the project’s implementation. To capitalize on the potential, additional turbines have been created and made accessible to businesses. The project needs to be cost-effective and successful, thus we need to explore the greatest hydro turbine option. The purpose of this paper is to investigate the selection process for hydroelectric projects’ hydro turbinesArjun ChaudharyShashank MishraShashank MishraShashank Mishra
