Abstract

Interesting studies on silver nanowires have been conducted in the disciplines of biotechnology and nanotechnology. They are very useful in antibacterial applications because of their conductive and antimicrobial qualities. When silver nanowires are synthesized using the right techniques, they can form nanoscale structures with more surface area, which improves their contact with bacteria and increases their antibacterial efficacy. The aim of this study was to create silver nanowires with ideal solvothermal characteristics and to evaluate the antimicrobial activity. By used ethylene glycol to reduce silver nitrate in polyvinylpyrrolidine at 160oC for 2.5 hours, silver nanowires were successfully produced. The products were examined using SEM, XRD, PSA, and UV-visible spectroscopy. The average size of silver nanowires was 123.0 nm and the highest inhibition zone was 2.33 cm. Overall, the synthesis and use of silver nanowires, with a focus on the solvothermal approach, holds great promise for treating bacterial infections and has a favorable influence on the environment and public health.

Abstract

Andaliman (Z. acanthopodium DC.), a plant belonging to the Zanthoxylum genus, is widely found in North Sumatra. Z. acanthopodium DC. has been traditionally used by local people to treat various diseases. Several secondary metabolites have been reported from the Zanthoxylum genus, including coumarins, flavonoids, lignans, terpenoids, steroids, amides, alkaloids, and phthalate derivatives. In this study, a phthalate derivative compound has been successfully isolated from the non-polar fraction of the stem wood of Z. acanthopodium DC., which was identified as di-(2-ethylhexyl) phthalate according to IR and NMR spectroscopic analyses.

Abstract

In the current trend of the upstream stage of microalgal bioprocessing studies, many works mainly focused on optimizing microalgal cultivation parameters for obtaining a high yield of either biomass or a particular metabolite. Meanwhile, efforts to alternatively provide affordable growth medium are considered still limited to be performed. This study aims to provide an alternative microalgal growth medium from commercial fertilizers and supplements provided by a particular Indonesian company. Our proposed microalgal growth medium was developed by considering the chemical contents of the products with the essential components of an established Guillard f/2 microalgal growth medium. By employing the developed growth medium in Chlorella pyrenoidosa and Botryococcus braunii cultivation, similar growth profiles were shown in both green microalgae with optimum time for biomass harvesting encouraged within two weeks of cultivation. Regarding biomass productivity, 0.19 g and 0.20 of dried biomass were averagely obtained from 1 L cultures of Chlorella pyrenoidosa and Botryococcus braunii, respectively. This finding implies that two Indonesian fertilizer products could be utilized as the main ingredient of moderate performance of green microalgal growth medium.

Abstract

This research aims to determine the optimum conditions for the synthesis of CaO nanoparticles using the coprecipitation method, determine the characteristics of the CaO nanoparticles synthesized, and determine the effect of the performance of CaO nanoparticles as an adsorbent for indigo carmine dyes. CaO nanoparticles were successfully synthesized using the coprecipitation method at the optimum conditions of 1 M NaOH concentration and formation temperature of 400+200℃ with the highest % yield reaching 74.56%. The successful formation of CaO nanoparticles was proven by the appearance of a 2-theta diffraction peak of 23.12°; 39.2°; 57.9°; and 67.2° which is identical to the lattice structure of CaO with hkl indices (200), (311), (422) and (600) and a crystal size of up to 4.96 nm. SEM images support the formation of CaO nanoparticles with an average particle size of 98.1 nm and a varying size distribution. The IR spectrum of the formation of CaO nanoparticles with the appearance of Ca-O peaks at wavelengths of 3640, 1400, 860, and 791 cm-1. The adsorption capacity of indigo carmine on CaO nanoparticles was greatest at an adsorbent dose of 10 mg, adsorbate concentration of 100 ppm and a contact time of 50 minutes. The most appropriate adsorption isotherm model and adsorption kinetics model was the Koble-Corrigan model and the pseudo second order model, respectively.

Abstract

Copper (Cu) is widely utilized as an electrode material due to its high conductivity and relatively low cost. This study aims to develop nanocomposite-modified Cu electrodes using polysulfone (PS), chitosan (CS), glutaraldehyde (GA), and zinc oxide (ZnO) to form PS-CS-GA/ZnO-NP modified Cu electrodes. The nanocomposite was prepared in the proportions of 48.8% PS, 24.4% CS, 24.4% ZnO, and 2.4% GA using the phase inversion method. The characterization of the PS-CS-GA/ZnO nanocomposite-modified Cu electrode was conducted using cyclic voltammetry with a 0.01 M K3[Fe(CN)6] in 0.1 M KCl. The cyclic voltammogram profile was obtained at a scan rate of 25 mV/s, exhibiting an ipa/ipc ratio of 0.93 within a potential of -1.5 to +0.4 V vs Ag/AgCl over 15 cycles. The FTIR spectrum of the PS-CS-GA/ZnO nanocomposite thin film displayed a peak at 1668 cm-1, indicating the presence of C=N groups, which suggests a cross-linking interaction between CS and GA.

Abstract

Antioxidants are used to neutralize free radicals. Mahogany leaves (Swietenia mahagoni (L.) Jacq) contain flavonoid chemicals that exhibit antioxidant properties. The purpose of the study was to determine the physical characteristics and antioxidant activity of sleeping mask gel preparations with the addition of mahogany leaf extract. Mahogany leaf extract is made using the maceration process. Determination of antioxidant activity using the DPPH method. The formulation is made by varying the concentration of mahogany leaf extract into 4 formulas, F0 (bases, F1 (0.0195%, IC50), F2 (0.0975%, 5xIC50) and F3 (0.195%, 10xIC50). There were several tests used to evaluate formulas, including homogeneity, dispersion, viscosity, pH, and organoleptic (odor, color, and shape) testing. IC50 value of mahogany leaf extract was 19.48 μg / mL. Mahogany leaf extract antioxidant gel sleeping mask preparations F0, F1, F2 and F3 was evaluated such as organoleptic testing requirements, homogeneity and pH produced between 6.15-6.65 including the skin's normal pH range of 4.0-7.0 during 28-day storage. F2 exhibits the best antioxidant stability, with an inhibition value of 54.59%.

Abstract

This article aims to determine the most effective ZnO-zeolite synthesis method for use as an adsorbent. The effectiveness of the ZnO-zeolite synthesis method includes the methods of synthesis, characterization, and adsorption. This study is a literature search using Google Scholar and Science Direct with the keywords “ZnO”, “zeolite”, “synthesis”, and “adsorption” taken from the last 10 years (2013-2023). Twenty-six articles were obtained, and selection was carried out so that 12 articles were obtained. There were 4 methods for ZnO-zeolite synthesis: (1) sol-gel, (2) impregnation, (3) coprecipitation, and (4) hydrothermal methods. The synthesis of ZnO-zeolite products was characterized using X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM), and their adsorption capacity was tested via UV-Vis spectroscopy. The hydrothermal synthesis method is the most effective method for the synthesis of ZnO-zeolite because it does not consume a large amount of energy, is a simple synthesis procedure, and has a large adsorption power. The resulting ZnO-zeolite has a crystal size of 1.540 mm and can adsorb up to 657.895 mg/g of the adsorbate).
