Abstract

This study investigates the effects of boron concentration on boron-doped diamond (BDD) electrodes for electrochemical sensors of ciprofloxacin. The effects of boron concentration, scan rate, and pH of BDD electrodes with boron concentrations of 0.1, 0.5, and 1% were examined to determine the optimal conditions. Furthermore, square wave voltammetry (SWV) in phosphate buffer pH 7 was used to analyze the electrochemical behavior of ciprofloxacin. The results revealed a linear calibration curve in the concentration range of 30–100 μM with a recovery of 85–110%. Meanwhile, BDD electrode with the highest boron concentration in this experiment (1%) showed a very low limit of detection of 0.17 μM, meaning that 1% BDD gave a highly sensitive and significant measurement result for the electrochemical sensor of ciprofloxacin. With the results given, this study provides new insights for controlling boron concentrations in diamond electrodes for the electrochemical sensors of quinolone antibiotics.

Abstract

Zinc Layered hydroxide (ZLH) is a layered material easily synthesized with a structure identical to brucite-like material. Due to the exchangeable anions in the interlayer compensating for the positive charge of a brucite-type layer, ZLH provides a wide application in many fields. This review focuses on the properties and method of synthesis of ZLH by giving an overview of intercalated guest anion in the interlayer of ZLH. The further discussion involved the application of intercalated guest anion in zinc layered hydroxide layer and its properties as a sensitizer, controlled release biomedical, and agriculture to provide the scientific community for research and development by giving current findings. This brief review also presents the success of anion intercalation for controlled release along with the kinetic model involved, which increases the bioavailability and effectiveness of the nanocomposite on its target. It shows the development of research on ZLH nanocomposites toward the sustainability of human life and the environment. This study implies that it is a source of knowledge for researchers about zinc-layered hydroxide materials involving synthesis methods and their application to produce more beneficial nanomaterials.

Abstract

This study analyzed MeHg in a fast, simple, low-waste, and accurate by using ultra-high liquid chromatography coupled with inductively coupled plasma mass spectrometry. Simple preparation by liquid extraction with sonication at room temperature was effective extract MeHg from Certified Reference Material (CRM) and shark meat samples. Effective MeHg separation was achieved in less than 300 s using a C18 Hypersil Gold analytical column with a mobile gradient phase of 0.5% (w/v) L-cysteine in 2% (v/v) HNO3 and 100% methanol. The MeHg was extracted from 100 mg of shark meat using 1 mL of 0.5% (w/v) L-cysteine in 2% (v/v) HNO3 and sonicated for 30 min. Analysis of certified reference material (DORM-4) showed values between the experimental and certified values. The observed limit of detection and quantification MeHg were 0.86 and 2.85 pg/L, respectively. This method was applied to measure MeHg in shark meat from Binuangeun areas. The MeHg concentration in Rhizoprionodon acutus was 0.22–0.63 mg/kg wet weight (w.w.), Squalus hemipinis 0.68–1.14 mg/kg w.w., and 0.29–1.22 mg/kg w.w. for Sphyrna lewini. This study provides a quick and easy method to evaluate MeHg in shark meat or other seafood products and applies to many samples in a single assay.

Abstract

This study reports for the first time the theoretical prediction of structural, electronic, elastic and optical properties of cubic BaLiCl3, BaLiBr3, and BaLiI3 perovskites. The corresponding properties of the well-known BaLiF3 are also theoretically investigated. Density Functional Theory (DFT) using the Generalized Gradient Approximation (GGA) was implemented within the Quantum Espresso package to investigate the properties of the perovskites. The results revealed that BaLiX3 (X = F, Cl, Br, and I) are in ionic crystal forms with optimized lattice parameters of 4.04, 4.90, 5.21, and 5.66 Å, respectively. The minor band gaps were found to be 6.62 eV (Γ→Γ), 4.29 eV (R→Γ), 3.50 eV (R→Γ), and 2.58 eV (R→Γ) for the respective compounds. The investigation of their elastic properties indicated that these perovskites are all mechanically stable, while only BaLiBr3 and BaLiI3 are malleable. Finally, the studied perovskites exhibit excellent optical properties, including low reflectivity and high absorption in the ultraviolet region. Hence, it is predicted that these perovskites are suitable for various optoelectronic applications involving absorption in the UV region. However, BaLiBr3 and BaLiI3 are more favorable than BaLiF3 and BaLiCl3 to be deposited as thin films due to their flexibility.

Abstract

Synthesis of three Schiff bases of 5-bromo-3-nitro salicylaldehyde containing different sulfonamide group antibiotic compounds and their Cu(II) complexes was carried out. Structures of all compounds were characterized with spectroscopic methods, including Fourier transform infrared, proton nuclear magnetic resonance, and elemental analysis. The in vitro antimicrobial activity of ligands and complexes against Gram-negative and Gram-positive bacteria and the yeast Candida albicans was evaluated. It was determined that the ligand and complexes showed outstanding antimicrobial activity against almost all of the microorganisms tested. It has been observed that the newly synthesized complexes have more antimicrobial effects than the corresponding ligands. It has been determined that the newly synthesized complexes have more antimicrobial effects than the others (E. coli, L. monocytogenes, and C. albicans), especially on Staphylococcus aureus and Pseudomonas aeruginosa.
