Abstract

This study aimed to find a correlation between the degree of tealight and the speckle image of the tea leaf by using numerical analysis and graphical analysis. Numerical analysis was done using THSP (Time History Of Speckle Patterns), COM (Co-occurrence Matrix), IM (Inertia Moment), and AVD (Average Value of Difference) values. The numbers used in the study showed that THSP and correlation measurements showed changes in the biological activity of tea leaves at all wilting levels. Meanwhile, the IM and AVD values showed significant changes after the tea leaves withered by 57.56%. COM analysis did not show any changes from high to low levels. THSP and correlation measurement showed changes in biological activity in tea leaves. Biological activity was high at high water content, and biological activity decreased as the water content in tea leaves decreased.

Abstract

The triple-layer Aurivillius compound Bi4Ti2.9Fe0.1O12 has been reported to exhibit both adsorption and photocatalytic properties and, therefore, can be used to remove organic waste such as antibiotic residues. In this study, the Bi4Ti2.9Fe0.1O12 compound was synthesized using the molten salt method. The diffractogram showed Bi4Ti2.9Fe0.1O12 compound was successfully synthesized with no impurity phases detected. Scanning electron microscopy (SEM) images revealed that the compound has a plate-like/sheet-agglomerated particle morphology, with sizes ranging from 2 to 6 μm. Band gap energy calculations showed that the Bi4Ti2.9Fe0.1O12 compound has a band gap of 2.74 eV (453 nm). Adsorption tests demonstrated that the compound could adsorb 54.47± 0.56% of ciprofloxacin. Adsorption-degradation tests over 30, 60, 90, and 120 minutes reduced ciprofloxacin c oncentration by 59.84±0.54, 64.05±0.056, 70.04±0.091, and 62.55±0.052%, respectively. It indicates that the adsorption mechanism is more dominant than the photocatalytic mechanism. This may be due to the large number of ciprofloxacin molecules adhering to the BIT surface, making it difficult for light to penetrate, thereby preventing the photocatalytic mechanism from operating at its maximum efficiency.

Abstract

The exploration of Dye-Sensitized Solar Cells (DSSC), especially regarding the photoanode, is steadily advancing. widely recognized, the photoanode plays a key role in absorbing light and facilitating electron generation, which is essential for the efficiency of Dye-Sensitized Solar Cells (DSSC). TiO2 is frequently used as photoanode due to its excellent stability and ability to effectively support dye molecules. However, in terms of enhancing light absorption and the electron transfer rate, doping with Carbon Quantum Dots (CQDs) in TiO2-based photoanodes has gained attention as a promising approach to improve efficiency. In this research, Carbon Quantum Dots (CQDs) were added to TiO2 to enhance its properties. Red CQDs and Yellow CQDs were incorporated into TiO2 at a concentration of 5%. The resulting composite materials were characterized using XRD, UV-Vis, and I-V measurements with a solar simulator. The XRD pattern confirmed the crystalline structure of TiO2 with incorporated CQDs. The optical properties of the CQD-TiO2 composites were analyzed through UV-Vis spectroscopy, revealing changes in light absorption. The DSSC performance parameters, including Jsc, Voc, FF, and η, were determined through I-V characterization using a solar simulator. The best DSSC performance was obtained by the sample with the addition of 5% Yellow CQDs, with an efficiency of 3.42%

Abstract

The Teapot Dome Basin in Wyoming is known to have significant hydrocarbon potential, but its distribution and characteristics need to be better understood. This study was conducted to analyze the presence of hydrocarbons in wells 25-1-X-14 and 64-JX-15 using 3D seismic interpretation. Envelope attributes and RMS attributes were used to identify prospective zones more accurately. The purpose of this study is to determine the results of 3D seismic data interpretation in determining the geological structure of hydrocarbons in well 25-1-X-14 and well 64-JX-15, and to determine the application of attribute envelope and rms in determining the geological structure of Teapot Dome. The method used in this research is a quantitative descriptive method, in which seismic data is numerically analyzed to describe the physical characteristics of the subsurface. The amplitude values used in this research are 10m, 20m, 30m, 40m, 50m, and 60m. Data processing is done in 3 stages, namely picking horizon, time structure map, surface attribute envelope, and RMS. The interpretation of the envelope attributes and RMS attributes shows high-amplitude bright spot zones that indicate hydrocarbons, especially in the sand section. The low amplitude areas in the shale section do not have hydrocarbon prospects. The analysis also confirmed a dominant anticline structure with an axis to the southwest of Teapot Dome.

Abstract

This study looks at how salt and solvent mix, as shown by the final positions of particles in a simulation. The simulation uses Lennard-Jones parameters and runs in a closed system with fixed energy. The goal is to see if the particles follow the Maxwell velocity distribution. When lithium hexafluorophosphate salt mixes with ethylene carbonate, solvation occurs. The simulation runs for 100 and 2000 steps to get accurate results. At the start, no chemical reactions or outside forces are involved just the natural movement of particles. For fluorine, after 2000 steps, the particles start to group in one area, showing the system isn’t balanced yet. Since velocity is linked to kinetic energy, it's important to look at the most common speeds of lithium, phosphorus (P), fluorine (F), and lithium-oxygen carbonyl (Li-OC). At 100 steps, the speed data looks good for lithium, phosphorus, and fluorine, except for how fluorine interacts with itself. So, the number of steps was increased to 2000. But even then, the particles don’t spread out fully, which isn’t realistic nature doesn’t leave space. That’s why the simulation should run up to 3000 steps for better, more realistic results.
