This paper investigates the effects of nanoparticle-enhanced phase change material (NPCM) on solar still operation and performance. Technical and economic aspects were considered, to show an advance on earlier works using virgin phase-change materials (PCM). Three types of nanoparticle (TiO 2 , CuO and GO) were impregnated individually at 0.3 weight% in paraffin to form NPCM-1, NPCM-2 and NPCM-3 respectively. Experiments were conducted with four solar stills (SS) each of 0.5 m 2 area using respectively paraffin (SSPCM), paraffin-TiO 2 (SSNPCM-1), paraffin-CuO (SSNPCM-2) and paraffin-GO (SSNPCM-3). There was observed an increase in thermal conductivity and a reduction in melting and solidification temperatures, with NPCM compared to PCM. The effects of NPCM on water temperature, storage temperature, hourly and annual productivity were determined. SSPCM, SSNPCM-1, SSNPCM-2 and SSNPCM-3 yielded 3.92, 4.94, 5.28 and 3.66 l/m 2 /day respectively, corresponding to 26 and 35% increases in productivity of SSNPCM-1 and 2 respectively over SSPCM. Economic analysis showed cost per liter

“…It can be seen, in Figure 2, that the modification of HEC by the benzyl group is apparent with a decrease in the intensity of the peak at 3347 cm À1 indicating a benzyl substitution of OH groups [69]. Indeed, the aromatic characteristic band elongations (=C-H) are situated between 3090 and 3033 cm À1 [70] and the aromatic C=Csp2 elongation vibrations are located at 1454 cm À1 [71]. In addition, the appearance of new absorption bands corresponding to the angular deformation (out of plane) of the monosubstituted aromatic C-H at around 740 cm À1 [72], and the C=C aromatic angular deformation, situated at 698 cm À1 , is a strong indication of the benzyl group incorporation on the HEC polymeric structure.…”

The main objective of the present work is to elaborate on a new eco-friendly and efficient adsorbent designated for aquatic micropollutants removal. However, the synthesis of the Ethylenediamine Crosslinked 2D-Cellulose green adsorbent was carried out successfully, by partial grafting of benzyl entities onto hydroxyl groups of HEC, and crosslinking with ethylenediamine ED. Further, the new ethylenediamine crosslinked 2D-Cellulose was used as a biosorbent for nanoencapsulation removal of copper and lead heavy metal ions from aqueous solutions. The proposal chemical structures of unmodified and modified materials were confirmed using FTIR, XRD, TGA, and SEM–EDX analysis. Furthermore, many parameters of the optimization for Pb (II) and Cu (II) in terms of removal efficiency including pH, adsorbent amount, and contact time were optimized by response surface methodology with a Box–Behnken design. Based on the desirability optimization with three factors, the maximal removal was 99.52% and 97.5% for Pb(II) and Cu(II), respectively and was obtained at pH = 5.94, 22.2 mg as the optimal adsorbent amount, and 21.53 min as contact time.

“…Gelatin is a protein obtained mostly from pig and cow skin, fish, and animal bones; hence, it is regarded as a renewable biodegradable material with the potential to be used in the development of preservation films with good gas permeability and high mechanical strength. 13 In addition, gelatin films have a comparatively high capacity for water absorption owing to their high inherent hydrophilicity. 14 Due to its cheap cost, availability, and good film-forming capabilities, carboxymethyl cellulose (CMC) is one of the oldest natural polysaccharides used widely in packaging.…”
