Estimation of the Diffusion Coefficient and Hydrodynamic Radius (Stokes Radius) for Inorganic Ions in Solution Depending on Molar Conductivity as Electro-Analytical Technique-A Review
Diffusion coefficient (D) and radiuses of inorganic charge ions (R) in different environments is of importance in scientific fields, explaining certain features of ions. D values were obtained using the Einstein-Smoluchowski equation depending on limiting molar conductivity (λo) of inorganic charge ions. Inorganic ions have D values at the range of 1−3×10−9 m2.s-1, except hydroxyl and hydrogen ion (5.2×10−9 and 9.1×10−9 m2.s-1, respectively). The hydrodynamic radius R for diffusing ions was calculated using the Stokes–Einstein equation based on D values. Inorganic ions have R, values at the range of 1−3×10−10 m, except hydroxyl and hydrogen ion (R=0.47×10−10 and 0.27×10−10 m, respectively).

Hydration thermodynamics and hydrodynamic (Stokes) radius of the lanthanide ions
Biochemical and physiological properties depend on the size of ions and the thermodynamic quantities of ion hydration in numerous states. The diffusion coefficient (D) of lanthanide series ions (Ln+3) in solution (1.558-1.618 ×10−9 m2 s−1) as calculated by the Einstein–Smoluchowski relation depended on conductance measurements as electro - analytical measurement. The association constant (KA) of Ln+3 ions (210.3-215.3 dm3 mole-1) was calculated by using the Shedlovsky method, and the hydrodynamic radius was (1.515-1.569 ×10−10 m) as calculated by Stokes–Einstein equation. ΔHo, values were obtained from the literature. The thermodynamic functions (ΔGo, ΔSo) were calculated by suitable equations, ΔGo, for ion hydration, had negative values in the range (13.25 - 13.31 kJ/mole), ΔSo also were of negative values, results have been shown in the limit (11.299 - 12.573 kJ/ K. mole).

Benefits of Consuming Citrus Fruits as Vitamin C Source in the Treatment of COVID-19
COVID-19- Citrus fruits- Vitamin C: COVID-19 is a virus that affects people unevenly with most cases showing mild symptoms, especially in children and young adults. However, some cases can appear severe and dangerous, as many patients require medical care in hospitals. Nutrition is very beneficial to health, especially in cases where it may need to strengthen the immune system, fruits are one choice in this field like citrus fruits (ex; oranges, clementine, and grapefruit) because it's a famous source of vitamin C. This letter focuses on introducing vitamin C's benefits in treating influenza and COVID-19 viruses.

The performance development of photovoltaic systems has become crucial with the increasing demand for renewable energy sources. Cooling systems play a crucial role in maintaining solar cell temperatures within optimal ranges, thereby improving their overall efficiency. This study presents an experimental investigation into the effectiveness of fan-based cooling systems aimed at enhancing the efficiency of solar cells. In this experiment, a cooling system was tested under limited environmental conditions to assess its impact on solar cell performance. It was concluded from the results that reducing the temperature using the air-cooling system did not significantly impact the efficiency of the solar cell when the temperature was below 50 degrees Celsius; however, the proposed cooling system was effective in reducing the temperature of the solar cell by 18 °C relative to the reference solar cell.
