In this work, the thermal performance enhancement of a shallow solar pond (SSP) was verified theoretically. The SSP operates under the open cycle to extract heat in order to increase own efficiency. SSP was provided with two transparent glass covers to reduce heat loss and increase global warming. It was also coated with a heat insulation material; the bottom of the SSP is painted in black to improve the absorption of solar radiation. In order to enhance heat extraction, five types of nanofluids with different physical properties were passed through a heat exchanger in the form of a serpentine welded to the bottom of the SSP. Five types of metal nanoparticles such as Al2O3, CuO, TiO2, SiO2, and Cu were mixed with pure water under various concentrations ranging from 0 to 5 % to obtain the nanofluids. A numerical model was developed based on the solution of thermal balance equations after discretization by using real meteorological conditions of the Medea city located in Algeria. The simulation was conducted on June 8 from 5 am to 6 am hours for the next day. The obtained results, including thermophysical properties, temperature of the pond and exergy performance, were presented and discussed.

A correlation between the degree of entropy and the electrophysical and magnetoresistive properties of film materials with different architecture in the paper establishes. It is established that the gradual decrease in thermal coefficient of resistance (TCR) during the transition from low-entropy (LEA) to high-entropy (HEA) alloys is explained by the fact that the resistivity in the direction of LEA HEA increases as a result of the decrease of the atoms mobility during the formation of basic phase and solid phase. It is shown that the temperature sensitivity of the resistance almost does not change depending on the entropy degree. The magnetic field dependences in all three measurement geometries differs only in amplitude and has all the GMR characteristics. It is concluded that the elements of granular state are realized in HEA films. At the same time, anisotropic magnetoresistance is observed for all cases of film material architecture under certain conditions which is caused not by spin-dependent electron scattering but by spin-orbital electron interaction, that is, the architecture of the samples does not play a prominent role.

Samarium doped cobalt ferrite, CoSmxFe2 – xO4 in which x varies as 0.0, 0.1, 0.3 and 0.5 were synthesized by conventional solid state reaction method. The impact of samarium doping on structural and dielectric properties is studied. The phase formation is confirmed by using XRD technique. The reflection peak broadening increases with increase in Sm concentration. The grain size is calculated by using scanning electron microscope image. The variation in dielectric constant () and dielectric loss (tan) as a function of frequency in the range 20 Hz to 1 MHz is studied. The dielectric constant is enhanced with increase in Sm concentration and decreases with increase in frequency.
