Accordingly, this research was conducted to turn pomegranate peel into a biochar adsorbent for the elimination of malachite green that is spiked in water. Initial dye concentration, pH, contact time, volume of solution, and adsorbent dose were the five primary factors taken into consideration while designing all the tests. An amorphous structure was detected in the pomegranate peel activated carbon by XRD. Surface area was analyzed using BET for the specific surface area of 46.363 m²/g. Scanning electron microscopy has been used to examine the surface characteristics, including porosity and cracks. At 200 mg/L, 16.3 mg, pH 7, and 100 min, the greatest dye removal efficiency and adsorption capacity of 99.85 % and 362.6 mg/g were recorded under testing circumstances. The adsorption process was preferred to follow the Freundlich model with R² of 0.9996. Moreover, the pseudo-second-order model suited the data better than the other kinetic models. The homogeneous, monolayer surfaces driven by chemisorption were the nature of the adsorption, as demonstrated by the kinetics and isotherm analysis. Moreover, the research of thermodynamics demonstrated that adsorption is endothermic (+58.9 kJ/mol) and spontaneous (ΔG &lt; 0). Finally, the regeneration of the adsorbent was investigated using four different eluents, and the potential for adsorbing other dyes was also evaluated. It can be concluded that industrial effluents could be effectively treated using the adsorbent material derived from pomegranate peel, as it is environmentally friendly, readily available, and possesses high adsorption capacity.</div></div>","PeriodicalId":21085,"journal":{"name":"Results in Surfaces and Interfaces","volume":"20 ","pages":"Article 100618"},"PeriodicalIF":0.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144829327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of chitosan, a biodegradable and renewable biopolymer, as a templating agent adds a green chemistry dimension to the synthesis approach. X-ray diffraction (XRD) and Fourier transform infrared (FT-IR) spectroscopy confirmed the formation of LaAlO₃. The morphology of LaAlO₃ was analysed using transmission electron microscopy (TEM). Surface area, pore size, and pore size distribution were determined via Brunauer-Emmett-Teller (BET) analysis, which confirmed its mesoporous nature. Surface acidity and basicity of nano-mesoporous LaAlO₃ were examined using temperature-programmed desorption (TPD-NH₃ and TPD-CO₂) techniques. TPD analysis revealed a higher number of surface acidic groups and a moderate presence of surface basic groups. Surface and bulk oxygen reducibility was assessed using temperature-programmed reduction (H₂-TPR) analysis. The results indicated that LaAlO₃ remains stable under reduction up to 500 °C and contains a limited number of reducible surface groups. The frequency dependence of capacitance, dissipation factor, and dielectric constant was analysed at room temperature. To better understand the conduction mechanism, the variation of AC conductivity with frequency was also measured. Nano-mesoporous LaAlO₃ exhibited a high capacitance and dielectric constant, along with low AC conductivity and a low dissipation factor in the low-frequency region. These properties suggest that nano-mesoporous LaAlO₃ holds significant promise for multifunctional applications, particularly in catalysis, energy storage devices such as supercapacitors and solid-state capacitors, gas sensing, and dielectric components in electronic devices.</div></div>","PeriodicalId":21085,"journal":{"name":"Results in Surfaces and Interfaces","volume":"20 ","pages":"Article 100631"},"PeriodicalIF":0.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144917469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The key novelty of this work lies in the integration of Response Surface Methodology (RSM) and Central Composite Design (CCD) for multi-response optimization, coupled with validation through experimental testing and microstructural analysis via Scanning Electron Microscopy (SEM). The influence of peak current (2–6 A), pulse-on time (10–40 μs), and pulse-off time (4–6 μs) was evaluated across response factors such as micro-hardness, edge deviation, overcut, material removal rate (MRR), taper angle, and tool wear rate (TWR).

This study aimed to assess the concentration, spatial distribution, and potential risks of 14 heavy metals (HMs)—As, Ba, Co, Cr, Cu, Mo, Ni, Pb, Rb, Sr, V, Y, Zn, and Zr—in 44 soil samples collected from granitic terrains across the region. X-ray fluorescence (XRF) analysis was conducted on powdered samples to determine metal concentrations. Multiple indices, including Geo-accumulation Index (I_geo), Contamination Factor (CF), Modified Pollution Index (MFPI), and Pollution Load Index (PLI), were applied to evaluate contamination levels. Ecological risks were quantified using the Potential Ecological Risk Index (PERI) and toxicity units. Sample S27 exhibited the highest PERI value (6.001756), primarily due to elevated Zn levels. Zinc (Zn) and Zirconium (Zr) were identified as major pollutants with strong anthropogenic signatures. As presented, the lowest ecological toxicity (0.189 ± 0.059). Human health risk assessments revealed dermal contact as the primary exposure pathway for both non-carcinogenic and carcinogenic effects, particularly for Zn, Cr, and Co. Ingestion and inhalation pathways posed relatively lower risks, with Cr_ingestion and Cr_inhalation averaging 0.041 ± 0.038 and 0.166 ± 0.051, respectively. Spatial analysis highlighted localized pollution hotspots. Overall, integrated pollution indices indicated moderate contamination, with areas of severe localized impact. This study emphasizes the urgent need for pollution mitigation strategies in granitic regions of South India, especially targeting Zn and Zr contamination and addressing dermal exposure pathways in human health risk management.</div></div>","PeriodicalId":21085,"journal":{"name":"Results in Surfaces and Interfaces","volume":"20 ","pages":"Article 100628"},"PeriodicalIF":0.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144924990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
