The choice of materials for building envelopes significantly influences the overall energy demand of HVAC systems, which contribute significantly to electricity usage. To enhance compatibility between grey clay and straw, a suggested approach involves using a composite material comprising rice water and grey clay, enriched with a high proportion of rice straw and soaked in rice water. This environmentally friendly technique yields a green construction material capable of reducing energy consumption in HVAC systems by up to 35.6% over a 24-h period.

Experimental results reveal that the suggested grey clay bricks, compared to traditional materials, exhibit superior physical characteristics such as compressive strength and load stability. These bricks are up to 41.2 mass% lighter than regular bricks due to the incorporation of rice straw, which enhances their mass reduction.

However, there are not enough studies to clarify the direct impact of LiBOB on the properties of PEO in polymer electrolytes. Therefore, the aim of this study is to clarify the dependence of the addition of the LiBOB salt on the structure, thermal properties and ionic conductivity of PEO. Solid polymer electrolytes with different ether oxygen to lithium ions molar ratios (EO/Li) (PEX) were prepared. Fourier transform infrared spectroscopy (FTIR) analysis showed that the salt concentration has affected the structure of PEO, especially its crystallinity as one of the most important properties affecting the ionic conductivity of PEO-based polymer electrolytes. These results were confirmed by differential scanning calorimetry (DSC) analysis as the degree of crystallinity decreases with the addition of salt. Moreover, DSC analysis revealed the composition of the samples at which crystallinity of PEO completely disappeared. Scanning electron microscopy (SEM) showed the modifications in surface morphological features of PEX as a function of LiBOB concentration. The results obtained from these studies were correlated with the most important result for the application of polymer electrolyte, that of electrochemical impedance spectroscopy (EIS). It revealed the maximum ionic conductivity at room temperature as high as 1.68∙10<sup>–4</sup> S cm<sup>⁻1</sup> for sample with EO/Li molar ratio 5. The importance of this result lies in the promising increase of five orders of magnitude compared to the ionic conductivity of PEO and in reaching the practical applicable ionic conductivity.

Nevertheless, most desalination methods are high energy and cost intensive. Solar desalination-based solar still is based on the principle of evaporation using solar energy and then condensation. It has been used as a simple, low-energy method in the past, but it suffers from low reliability and indigent overall performance. Hence, in this work, to enhance the performance of solar distillers, the high capillarity of a jute wick has been used as the foundation for a unique type of solar still. This style of solar still has a blackened trapezoidal pyramidal base and polycarbonate cover that is still trapezoidal. A jute cloth was placed on an adjustable foundation that could be adjusted levelwise with the intention of understanding the impact of the distance between the jute and the polycarbonate cover. This study examined several gaps to identify the ideal gap for the highest level of production. Additionally, each experiment was compared with a conventional solar still. The study's findings revealed that the gap spaces have a significant impact on productivity. The measured yields at different gaps between the absorber and condensation cover (H1 = 15 cm, H2 = 10 cm, and H3 = 5 cm) are 3800, 4600, and 5625 mL, respectively. Additionally, floating-wick solar stills produce more energy than conventional basin-type stills and need less operation and maintenance with higher energy and exergy hourly efficiency. For the production cost, the cost of the proposed still was lowered by 4.1, 20.5, and 34.2%, respectively, at each depth H1, H2, and H3.
