Summary: Researchers have made considerable progress in improving the productivity of solar stills by increasing the evaporation and condensation rates. Methods such as adding heat storage materials, using nanoparticles, changing the absorption plate structure, and utilizing photothermal materials can enhance evaporation rates, while cooling the condensing surface, increasing the condensation area, altering condensing surface wettability, and using a separate condenser can improve condensation rates. Advantages and disadvantages of each method are compared, and an economic analysis of current and future developments is included in the paper, providing insights for low cost and high productivity in researching solar stills.

Summary: The demand for freshwater is increasing exponentially, resulting in increased pollution of environmental assets due to industrial and manufacturing growth. Solar distillation is a straightforward and inexpensive technology to produce freshwater. Wick-type solar stills (WSSs) have been found to be efficient and effective, improving efficiency by around 60% compared to traditional systems. Installing a multi-wick basin-type inverted absorber solar still (MWBIASS) further enhances energy efficiency, destroyed exergy percentage, and annual cost.

Summary: This study investigates the influence of Cerium (Ce3+) on CoCr2-xCexO4 (CoCrCe) in terms of its structural, microstructural, Fourier infrared spectroscopy, and LPG sensing behavior. The samples were created using the solution combustion technique and sintered to achieve a pure crystalline structure. X-ray diffraction analysis confirmed the production of cubic spinel structures, while FTIR analysis confirmed the absence of impurities. Scanning Electron microscopy revealed the samples' porous microstructures. Elemental analysis confirmed the presence of all elements. The study also demonstrates that the CoCr1.98Ce0.02O4 thin film can be used as a highly sensitive gas sensor for detecting LPG at room temperature.

Summary: We report the formation of hexagonal nano-sheets of pure and Co-doped ZnO thin films using aerosol-assisted chemical vapor deposition technique. Two phases of ZnO, Wurtzite and Zinc blende, were observed in the films by X-Ray diffraction. Scanning electron microscope images show the formation of hexagonal nano-sheets on the substrate surface. Beer's law was used to determine the band gap of the films. The performance of both films as UV detectors was investigated, with the response/decay time showing large values. Co-doping decreased the response time while increasing the decay time. The Co-doped ZnO films exhibited a minimum response time of 4s at 5V applied voltage, but had a lower gain value compared to the pure film.

Summary: In this study, the effect of Cr3+ content on the distinctive features of Cr3+ doped ZnO nanoparticles synthesized through auto-combustion using leucine as the fuel was investigated. The analysis of the synthesized powders using XRD, UV-Visible, and Photoluminescence spectroscopy showed that the presence of fuel and Cr3+ content influenced the structural, optical, and luminescence characteristics of the nanoparticles. The results revealed that the addition of Cr3+ reduced the crystallite size while increasing lattice parameters, unit cell volume, strain, and dislocation density. Furthermore, the emission and photocatalytic activity of the Cr3+ doped ZnO nanoparticles were also examined, demonstrating their potential for future optoelectronic and photocatalytic applications.

The results show the formation of single-phase nanocrystalline particles with Cu2+ substitution at the Zn2+ site. Cu2+ doping leads to structural changes and band gap narrowing, resulting in improved photocatalytic activity and antimicrobial activity. The prepared nanoparticles also exhibit significant photoelectrochemical performance, suggesting their potential application in photoelectrochemical sensors.
