Abstract

This research is concerned with the synthesis and characterization of a composite material that may be used as a battery electrode. Bismuth oxide (Bi2O3) was synthesized from Bi(NO3)3·5H2O, Na2SO4, and NaOH mixed with commercial activated carbon and graphite. The composite formation process was carried out using the hydrothermal method at 110 °C for 5 h. The characterization data indicated the composites produced contained Bi2O3 with a monoclinic crystal system, and Bi2O3 particles were evenly distributed in the composite. The composites were characterized to be mesoporous, with the electrical conductivity reaching 10−1 S m−1. The development of this composite material has potential applications in the field of energy storage, particularly in the development of battery anode.

Abstract

The disposal of dye wastewater has become a major global concern. Meanwhile, microorganisms have shown high potential in the treatment of wastewater pollutants. In this study, the involvement of the Fenton reaction in the biodecolorization and biodegradation of methylene blue (MB) by the brown rot fungus Daedalea dickinsii was investigated. Subsequently, D. dickinsii is a fungus capable of producing hydroxyl radicals (•OH). This experiment was conducted with an initial MB concentration of 75 mg/L, and different incubation times of 0, 7, 14, 21, and 28 d respectively. The result showed that the Fenton reaction played an important role, and this was demonstrated by the addition of FeSO4 as a Fe2+ source. The removal of MB by D. dickinsii with the addition of Fe2+ reached 91.454% at 28 d in a mineral salt medium. It was higher compared to D. dickinsii culture treatment without Fe2+ addition, 86.427%. Furthermore, the metabolic degradation product was analyzed using LC-TOF/MS and identified as 2-amino-3-hydroxy-5-(methylamino) benzenesulfonic acid and N-(3,4-dihydroxy phenyl)-N-methyl formamide.

Abstract

Heterocyclic 1,4-di(1,3,5-dithiazinan-5-yl)benzene (D) and two heterocyclic-cationic Gemini surfactant 5,5'-(1,4-phenylene)bis(5-decyl-1,3,5-dithiazinan-5-ium)bromide (E) and 5,5'-(1,4-phenylene)bis(5-tetradecyl-1,3,5-dithiazinan-5-ium)bromide (F) were prepared and identified by FTIR, 1H-NMR spectroscopies, and GC–MS. Then, they were tested as corrosion inhibitors against carbon steel corrosion in 2.0 M aggressive HCl medium at 25 and 50 °C. They have different carbon chain tails, i.e., E (10 carbons), and F (14 carbons). These new heterocyclic and surfactant categories as corrosion inhibitors. The corrosion process has been studied electrochemically (Tafel Plot). The inhibition efficiency clarified that the decrease in IE(%) is in the order of F > E > D. The biological activity of compounds D and F was investigated using the aforementioned drilling procedure with a cork drill. At a dosage of 3000 mcg/mL, the biological action of compound D demonstrated effective resistance against the two types of negative bacteria. The cation has a diameter of 20 mm against E. coli and 19 mm against S. epidermis bacteria. At the same concentration, the chemical F is solely effective against E. coli with an inhibition diameter of 14 mm.

Abstract

Fishbone-derived carbon sulfonate, modified through incipient wetness impregnation with titanium tetraisopropoxide and iron nitrate salts, displays catalytic activity in the oxidation of styrene with hydrogen peroxide (H2O2) as an oxidant. This was done to develop a cost-effective, non-toxic, and environmentally friendly bimetallic oxide catalyst, incorporating titanium and iron oxides on mesoporous-derived carbon fishbone to enhance styrene conversion and benzaldehyde selectivity in styrene oxidation using aqueous H2O2. The catalyst, featuring a combination of titanium and iron oxides on the surface of the fishbone-derived carbon sulfonate, demonstrates higher catalytic activity than single oxide catalysts, such as titanium or iron oxides alone. Factors influencing the catalyst's performance are investigated by using FTIR, XRD, XRF, SEM, and BET surface area. The results reveal that the presence of both titanium and iron oxides on the surface of the fishbone-derived carbon sulfonate and the catalyst's surface area creates a synergistic effect, the primary factors affecting its catalytic activity in styrene oxidation using H2O2 as an oxidant.

Abstract

Due to the scarcity, studying precious metals extraction such as gold, platinum, and palladium is very critical. Solvent extraction is one of the established methods due to its simplicity and quickness but the low operational cost. In this study, a deep eutectic solvent (DES) consisting of decanoic acid and lidocaine in the molar ratio of 2:1 was applied as an extractant to extract Au(III), Pt(IV), and Pd(II) from aqueous media. Au(III) was solvated and extracted with DES in the form of AuCl3. Pd(II) was extracted by the cation exchange reaction between Pd2+ and H+. Complete extraction of Au(III) 98.2% and Pd(II) 100% can be achieved using 500 and 300 g/L DES, respectively. This finding opens new opportunities for improving Au(III) and Pd(II) extraction using an environmental friendly and inexpensive extractant.

Abstract

The approach to the synthesis of cerium oxide nanoparticles (CeO2NPs) using plants as capping agents has been widely researched because of its eco-friendly, low-cost, simple, effective, and reusability. In this research, we used Moringa oleifera leaf extract-mediated CeO2NPs. CeO2NPs were characterized by XRD, FTIR, SEM, TEM, and DRS UV-vis. The photocatalytic activity of CeO2NPs was tested using a phenol dye concentration of 7 mg/L with variations in photocatalyst weight of 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 mg under UV irradiation, respectively, with time variations of 15, 30, 45, 60, 75, 90, 105, 120, 135, and 150 min. SEM and TEM morphology results showed that the CeO2NPs were spherical and agglomerated. The crystal structure is cubic, with a crystal size of 18 nm with a band gap of 2.87 eV. CeO2NPs showed high photo-degradation phenol dye of 94.45% under visible light in 120 min irradiation time. The results show that M. oleifera leaf extract could be as inexpensive and safe for synthesizing other metal oxide nanoparticles, potentially having applications in the biomedical and environmental fields.

Abstract

In this work, new compounds of amide derivatives (C1-C3) were synthesized through the conversion reaction of p-chloroaniline to diazonium salt (B1), which reacts with aniline to form a new azo-compound (B3). Synthesized of p-alkoxybenzoic acid (A1-A3) and reacts with SOCl2 to form A4-A6 compounds that react with B3 compound to form amide compounds (C1-C3). The synthesized derivatives were tested by docking analysis and characterized via FTIR, 1H-NMR spectra. In the docking study, the interaction diagram also displays many van der Waals interactions, which are used to estimate the synthetic compounds' activity as insecticides like anti-termites. Heptyl came in first on the binding score, followed by octyl and then nonyl. Due to the compounds' modified conformation in interacting with the enzyme's binding pocket, the length of the alkyl residue of the derivative adversely impacted their binding inhibition. The synthesized compounds (C1 and C3) give a good result as anti-E. coli and anti-Staphylococcus strains.

Abstract

Paracetamol contained in wastewater can cause adverse effects on animal ecosystems, such as fish living in waters and cause harmful effects on humans. Adsorption techniques are used to remove these pharmaceutical compounds. Alginate-chitosan nanoparticles are non-toxic and effectively used as adsorbents to remove pharmaceutical compounds in wastewater. Research on glutaraldehyde crosslinked alginate-chitosan nanoparticles as paracetamol adsorbent has been carried out. This research used the ionic gelation method. Nanoparticles were characterized using transmission electron microscopy (TEM), scanning electron microscope (SEM-EDX) and Fourier transform infra-red spectrophotometer (FTIR). Furthermore, the nanoparticles were used for paracetamol adsorption. The results showed that the form nanoparticles are coarse solid powder and brownish yellow. The TEM image shows an average nanoparticle size of 8.22 nm. Glutaraldehyde crosslinked alginate-chitosan nanoparticles adsorbed paracetamol with adsorption kinetics followed a pseudo-second-order or Ho-McKay model, the adsorption rate constant of 0.0324 g mg−1 min−1. The isotherm study of paracetamol adsorption by glutaraldehyde cross-linked alginate-chitosan nanoparticles followed the isotherm Dubinin-Radushkevich isotherm model with a free energy value of 707.1068 kJ mol−1, and this value indicates the adsorption process by chemically or chemisorption.

Abstract

A green, convenient, and scalable synthesis of alcohols through the reduction of aldehydes and ketones has been developed. The green reduction was conducted using two different methods, namely sonochemistry and mechanochemistry. In the former method, the solution of aldehydes or ketones and sodium borohydride was irradiated under ultrasound irradiation. In the latter technique, the reaction mixture was ground under solvent-free conditions. The reduction reaction was performed at room temperature and completed in only 10 min using both protocols. The results showed that aldehydes and ketones with aromatic, heteroaromatic, and aliphatic motifs were tolerated under the reaction conditions, allowing the formation of the corresponding alcohols with the synthetic yields of 75–98% and 77–95% for grinding and sonication methods, respectively. In addition, the reaction can be carried out on a multigram scale.

Abstract

The study focused on producing and examining the properties of the 2-(((3-mercapto-5-(4-nitrophenyl)-4H-1,2,4-triazol-4-yl)imino)methyl)-4-(((4-mercaptophenyl) diazenyl)phenol) ligand (L) and its complexes with three transition metal ions, namely Ni(II), Co(II), and Cu(II). The ligand was formed through diazotization and coupling reactions between 4-aminobenzenethiol and a coupling Schiff base derived from 1,2,4-triazole. The characterization of the ligand and its metal ion complexes was carried out using analytical techniques such as FTIR, 1H- and 13C-NMR, UV-visible spectroscopy, and thermal analysis (TGA and DTG). Various physical methods were employed to synthesize and analyze the properties of the three mononuclear Co(II), Ni(II), and Cu(II) complexes with the azo-dye Schiff's base ligand. Based on the microanalysis and spectroscopic results, it was determined that the coordination between the azo Schiff base ligand and the central metal ion occurred through the NOS-donating atoms of the ligand. The analysis of the electronic spectra revealed that the synthesized Co(II) and Ni(II) complexes  exhibited an octahedral geometry, while the Cu(II) complex had a distorted octahedral geometry. The implications of the finding regarding the octahedral and distorted-octahedral geometries include expanding the structural diversity in coordination chemistry, providing insights into ligand-metal interactions, and understanding the influence of geometry on properties.
