The physical properties of CsGeCl₃ are investigated under pressure in steps of 1.0 GPa. The CASTEP and GGA-PBE technique is used to understand the characteristics of cubic-based CsGeCl₃ crystal structures with space group 221. The energy bandgap (BG) exhibited direct semiconductors to metallic transition nature at pressures and its value decreased from 1.06 to 0.0 eV. It is observed during computations that it maintains the cubic phase with lattice parameters decreasing from 5.33 to 5.02 Å. A thorough analysis of optical characteristics under pressure shows that the UV spectrum region corresponds to strong peaks in optical properties, with a slight shift in peaks towards greater energies. Additionally, it satisfies the Born stability for mechanical stability and has an anisotropic (A) nature due to the anisotropic factor (0.529 to 1.501) of unity. The ductile nature of CsGeCl₃ is indicated by the Poisson scale (0.260 to 0.289) limits and Pugh’s ratio (1.751 to 2.037). If Cauchy pressure (C_p) is low, the material shows non-metallic behavior, and at high pressures, it shows metallic behavior, with a range of 1.299 to 9.961 GPa. As a result, the analysis shows that said material is suitable for photovoltaic and optoelectronic activity.</p></div>","PeriodicalId":692,"journal":{"name":"Materials for Renewable and Sustainable Energy","volume":"14 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40243-024-00276-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142679578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The major raw material (oil) was obtained by steam distillation (SD) from Croton heliotropiifolius Kunth leaf (CHKL) and was characterized for its aptness for biodiesel production. Dwarft green coconut husk ash (DGCHA) was used as a bio-adsorbent for acid value reduction of Croton heliotropiifolius Kunth leaves oil (CHKLO). A novel, highly potassium-based catalyst was derived from Karpuravalli banana peels (KBP), calcined, and characterized using TGA, ZETA, FTIR, SEM-EDX, XRF-FS, and BET analysis. Biodiesel was synthesized using a microwave-assisted method, characterized, and compared with the recommended standard. The catalytic strength of the calcined Karpuravalli banana peel powder (CKBPP) was tested using a reusability test, and the cost evaluation of production was estimated. Results showed that the CHKL was rich in oil (43% wt./wt.), and the oil is highly acidic (5.23 mg KOH/g oil). At high particle size, the dwarf green coconut husk ash (DGCHA) bagasse reduced the acid value to a minimum (1.4 mg KOH/g oil) at 3 days. The developed novel catalyst from CKBPP indicated high potassium-calcium contents for base transesterification. Process optimization indicated that the predicted response data of 95.285% (wt./wt.) at T₁ = 90 min, T₂ = 60 ^oC, T₃ = 4.5% (wt.), and T₄ = 9 (vol./vol.) was validated in triplicate, and the average data value of 95.10% (wt./wt.) was established.

Lemon peel discarded by restaurants after juice extraction is carbonized at 400 ⁰C followed by chemical activation using ZnCl₂. The porosity of carbon materials is tailored by varying activation conditions, such as the mass ratio of carbonized lemon peel and ZnCl₂, duration of heating, and temperature. The Brunauer–Emmett– Teller (BET) surface area and pore volume of carbon materials prepared at different activating conditions range from 1380 to 2120 m²g⁻¹ and 0.38 to 0.69 cm³ g⁻¹ respectively. The derived carbon materials are amorphous indicated by the broad peaks in the XRD pattern as well as disordered structure of the carbon materials is revealed by the Raman spectroscopic analysis. The systematic analysis of capacitive performance of activated carbons by employing electrochemical techniques like Cyclic Voltammetry (CV), Galvanostatic charge/Discharge (GCD) cycles, and electrochemical impedance spectroscopy (EIS) in acidic (H₂SO₄) and alkaline (KOH) media indicates that optimum condition for activation of lemon peel is 600 °C for 60 min with 1:1 mass ratio of carbonized lemon peel and ZnCl₂. The superior performance of (ALP-600) is attributed to its high surface area and well-connected hierarchical porous structure.
