B-SITE SUBSTITUTION EFFECTS (Fe, Mn, Ni) ON THE STRUCTURAL, ELECTRONIC, AND ELECTROCHEMICAL PROPERTIES OF La₀.₇Sr₀.₃BO₃ PEROVSKITES FOR INTERMEDIATE-TEMPERATURE SOFC CATHODES
The shift toward low-emission energy technologies is increasing interest in intermediate-temperature solid oxide fuel cells (IT-SOFCs), where cathode performance is crucial for system efficiency and durability. The perovskite compound La₀.₇Sr₀.₃BO₃ (B = Fe, Mn, Ni) is promising as a cathode material due to its flexible crystal structure and mixed ionic–electronic conductivity (MIEC) properties. This article comparatively reviews three main systems: La₀.₇Sr₀.₃FeO₃, La₀.₇Sr₀.₃MnO₃, and La₀.₇Sr₀.₃NiO₃ based on their crystal structure, metal ion valence, oxygen vacancy concentration, conductivity, oxygen reduction reaction (ORR) activity, and thermal and chemical stability. The analysis results indicate a trade-off between electrochemical activity and stability: the Fe system has high stability but moderate activity, the Mn system offers a balance of both, while the Ni system shows the highest activity but is susceptible to high-temperature degradation. Optimization of the composition and oxygen vacancy (δ ≈ 0.10–0.18) can improve the conductivity without compromising crystal stability. This study emphasizes the importance of composition engineering, surface modification, and composite cathode fabrication to produce more efficient and durable next-generation IT-SOFC perovskite cathodes.

POTENTIAL BIOACTIVE COMPOUND OF Curcuma Longa AND Phyllanthus Niruri AS CANDIDAT NANO HERBAL FOR CHEMOPREVEPOTENTIAL BIOACTIVE COMPOUND OF Curcuma Longa AND Phyllanthus Niruri AS CANDIDNTION AGENT TROUGH INHIBITING EPIDERMAL GROWTH FACTOR RECEPTOR (EGFR)
Chemopreventive agents derived from herbs are increasingly being explored as potential adjuncts or alternatives to cancer therapies, including Curcuma longa and Phyllanthus niruri. This study evaluates the potential efficacy of bioactive compounds as anti-proliferative to prevent the growth of cancer cells by binding to the epidermal growth factor receptor (EGFR), which has potential as a chemopreventive agent using a bioinformatics approach. The data was collected from a previous study. Next, the selected compounds' 3D structures and canonical smiles were obtained from the PubChem database, and EGFR 7aei protein data from RSCD PDB databases as protein targets for further analysis. The data were analyzed based on probable activity, molecular docking, and molecular dynamics using a PASS Online web server, PyRx Software, YASARA software, and the AMBER14 force field, respectively. The Discovery Studio 2019 software was used to generate 3D visualizations of the results obtained from the molecular docking analysis. The bioactive compounds C. longa and P. niruri have the potential to target EGFR. The potential compounds showed a strong bond with EGFR. The strongest bond are lupeol, isoquercitrin, and quercetin, with binding affinity values of -9.3, -8.6, and -8.6, respectively. The result of RMSD showed that potential compounds fluctuate more stability when interacting with the EGFR compared with the control, as seen from the RMSD value of the ligand-complex simulation 5.03 Å, 3.29 Å, 3.9 Å, and 4.57 Å for gefitinib (control), quercetin, isoquercetin, and lupeol, respectively. In summary, bioactive compounds from C. longa and P. niruri have the potential to prevent malignancy of cancer cells by targeting EGFR, which indicates the potential ability for chemopreventive activity
Synthesis of Coconut Shell–Derived Charcoal Nanoparticles for the Reduction of Hydrogen Sulfide and Ammonia in Odorous Liquid Waste
The use of activated carbon in coconut shells in the form of nanoparticles effectively and optimally can absorb contaminants. The synthesis of CSCNPs is the manufacture of activated charcoal nanoparticles with the use of coconut shells as the main material. Restaurant industry activities often become a trigger for environmental problems in Indonesia because they produce waste containing high levels of ammonia and organic materials, resulting in a strong odor due to incomplete anaerobic decomposition. This study aims to obtain the most effective method of making CSCNPs and the analysis of the most effective addition of Coconut Shell–Derived Charcoal Nanoparticles (CSCNPs) concentration in reducing the smell of UNESA food court liquid waste with hydrogen sulfide (H2S) and ammonia (NH3) parameters. This parameter was chosen because they are both the main chemical indicators of the cause of strong odor pollution (such as rotten eggs and pee smell) that interfere with the environmental comfort of the UNESA Food Court. The measurement of these two parameters aims to scientifically prove the effectiveness of Coconut Shell Coconut Shell–Derived Charcoal Nanoparticles (CSCNPs) in eliminating odor sources due to the anaerobic decomposition of organic waste. The method used in the synthesis of CSCNPs is the hydrothermal method. Analysis of the effectiveness of CSCNPs in reducing H2S using the methylene blue method and NH3 absorption using the phenol method based on UV-Vis spectrophotometry. Data analysis was carried out in a quantitative descriptive manner by calculating the mean value and the standard deviation of the absorbent. In this study, the concentration of CSCNPs which had the highest effectiveness in reducing H2S gas from 1.173 mg/L to 0.145 mg/L, was at the level of 0.07 g and the absorption of NH3 from 1.963 mg/L to 0.000 mg/L (in total) was at the level of 0.03 g. In addition, 0.05 g of CSCNPs was able to normalize the degree of acidity of the waste with a sample pH of 8 to 7 (neutral). CSCNPs has the potential to provide a solution to environmental problems, particularly in reducing unpleasant odors in liquid waste. In future research, it is expected to investigate whether CSCNPs can reduce contaminants using parameters other than H2S and ammonia as sources of environmental problems.
The Eco-Friendly Nanoparticle Synthesis Using Annona Species: A Comprehensive Review
Genera within the family Annonaceae, such as Annona squamosa, Annona reticulata, and Annona muricata, are sought for their nutraceutical and medicinal properties. These plants have a high phytochemical content and exhibit antibacterial properties, antioxidant compounds, and anticancer effects. The Annonas green methods are environmentally friendly agents as "green nanotechnology." Many nanoparticles, such as silver, gold, zinc oxide, copper oxide, magnesium oxide, and selenium, have been produced and characterized with various morphologies at the nanoscale. Green synthesis is safer and more cost-effective and has promising potential in moving forward medical advances in comparison to chemical methods of synthesis.
