Abstract

NANORODS ZnO THIN FILM PERFORMANCE AS TRANSPARENT HEATERS. Transparent heaters have been used for various applications. In this research, a transparent heater made from ZnO nanorods has been successfully fabricated. ZnO nanorods were produced by using the chemical bath deposition method.The results of the XRD investigation showed that the ZnO_0.015 and ZnO_0.025 samples contained three and five ZnO peaks, respectively, with a hexagonal wurtzite crystal structure. The crystallite size increased along with the increase in the solution concentration from 71.198 nm to 82.924 nm. The morphological characterization of the samples using FE-SEM showed that ZnO_0.025 sample had a better surface covarege than ZnO_0.015 sample. The average diameters of ZnO_0.015 and ZnO_0.025 are 127.130 and 146.756 nm, respectively. The transmittance value decreased along with the increase of solution concentration which is from 55% to 53%. The value of the band gap energy decreased as the concentration of the seed solution increased from 3.25 eV to 3.20 eV. The resistivity values of ZnO_0.015 and ZnO_0.025 are 1.126 x 10-4 and 0.824 x 10-4Ωcm, respectively. From these results it appears that ZnO_0.025 sample has a more optimal performance as a transparent heater compared to ZnO_0.015 sample.

Abstract

THE ADVANCED ELECTRIC FIELD FROM QUAD-ELECTRODE MODE FOR BLOOD CANCER TRAPPING: SIMULATION STUDY. Blood cancer is a disease caused by the rapid cleavage of white blood cells (WBC), which increases in the human circulatory system. Furthermore, based on the original nature of WBC during cleavage, which is the same as ionic bonds, electric field filtering, and trapping is used to treat leukemia patients. The electric field generated by the electrode with an AC voltage source plays a role in the migration of the WBC to high electric field intensity. The Quad-electrode field distribution is conducted using the Finite Element Method (FEM), and an electric field gradient analysis is conducted to determine the effectiveness of each coordinate system. According to the simulation results, the second model with an input voltage of 0.68 V has the highest intensity of electric field distribution, with an effective depth at Z = 30 mm, and the best coordinate along the X-axis and Y-axis are 30 mm. In conclusion, the center of the Quad-electrode system center is the best location for placing filters and trapping leukocytes by utilizing electric field distribution on the electrode system for the development of blood cancer biomedical therapy technology.

Abstract

MECHANICAL PROPERTIES OF PINEAPPLE LEAF FIBER/ EPOXY COMPOSITES WITH 0°/0°/0°/0° AND 0°/90°/0°/90° FIBER ORIENTATIONS. Pineapple leaf fiber can replace synthetic fiber because of its environmentally friendly and abundant availability in Indonesia. The purpose of this study was to obtain the mechanical properties of the pineapple leaf fiber/epoxy composite with 0°/0°/0°/0° and 0°/90°/0°/90° fiber orientations. Pineapple leaf fiber from Subang Indonesia was pre-treated through alkalization. The composites were fabricated by hand lay-up, followed by the vacuum bagging method. The results showed that the flexural properties of both composites were higher than the tensile properties of both composites. The flexural strength and modulus of 0°/0°/0°/0° composites were higher than those of 0°/90°/0°/90° composites, with the values of (109.57 ± 8.12) MPa and (7.08 ± 0.62) GPa respectively. Morphological observations using a Scanning Electron Microscope (SEM) showed that pineapple leaf fiber and epoxy had strong interfacial bonds and few voids. According to SNI 01-4449-2006 for fiberboard, pineapple leaf fiber/ epoxy composites with 0°/0°/0°/0° and 0°/90°/0°/90° fiber orientations were categorized as high-density fiberboard type T2 45, because both composites had a density higher than 0.84 g/cm3 and a flexural strength higher than 45 MPa.

Abstract

Ag AND Pd FISSION PRODUCT IMPLANTATION ON SiC LAYER IN TRISO FUEL PARTICLE OF HTGR USING SRIM/TRIM MONTE CARLO COMPUTER. Silicon Carbide (SiC) has excellent characteristics such as wide band gap, high electron mobility, high thermal conductivity, and radiation effects resistance. Therefore, SiC is widely used for various applications, including nuclear fuel systems. SiC is used in TRISO (Tri-Structural Isotropic) coated fuel particle in HTGR (High Temperature Gas cooled Reactor). TRISO, which consists of Inner Pyrolitic Carbon, SiC, and Outer Pyrolitic Carbon, is one of the safety systems features of the reactor. However, one of the issues of the system is corrosion of SiC caused by silver (Ag) and palladium (Pd). Nevertheless, the detailed mechanism of this corrosion phenomenon, such as the existence of Ag and Pd and how deep those two fission products penetrate the SiC layer, are still unknown. This study aims to investigate the physical interaction of Ag and Pd with the SiC coating layer of TRISO nuclear fuel particles. For this purpose, the physical effect of the penetration of the energetic Pd and Ag fission products into the SiC layer has been simulated using SRIM (Stopping and Range of Ions in Matter) /TRIM (TRansport of Ions in Matter) computer code with Monte Carlo method. Various Ag and Pd ion kinetic energies have been employed in this simulation. The results showed the Ag/SiC and Pd/SiC Ion Ranges, Doses, and Damage as the first-step evaluation to understand the corrosion phenomenon of the SiC-layer in the TRISO particles of HTGR.

Abstract

TEXTURE CHARACTERIZATION OF THE COPPER PRODUCED BY ECAP PROCESS USING NEUTRON DIFFRACTION TECHNIQUE. Texture and hardness characterization have been carried out on market copper samples that have gone through the equal channel angular pressing (ECAP) process. Neutron diffraction technique had been used for obtaining an average crystalline texture in a particular volume non destructively to the sample. The ECAP process is carried out once (1 pass) with some parts that have been plastically deformed and some parts that have not been deformed. Crystalline texture and hardness were observed in the deformed and non-deformed parts. Initial characterization was carried out by X-ray diffraction (XRD) followed by measurement of crystal texture using the neutron diffraction technique, while hardness was tested using the Vickers method. Rod-shaped sample with a diameter of 10 mm. Texture observations were performed at the center of the sample with a neutron beam limiting slit of 5x5 mm2 . There was an increase in hardness in the deformed position compared to the undeformed one. The texture that occurs is in the form of fibers with different directions and indexes, sequentially as follows: position 1, [111] of 4.96 m.r.d., position 2, -[111] of 1.86 m.r.d. and position 3 [010] of 2.44 m.r.d. , position 4 orientation is distributed on [011], [013], [115], [235] fibers with a texture index range of 1.07–1.33 m.r.d.

Abstract

Aluminum oxide (Al2O3) nanoparticles have been synthesized through a biosynthesis approach, employing Syzygium aromaticum leaf extracts prepared under varying acidic conditions as bioreductants in the reaction with aluminum nitrate nanohydrate. The Al2O3 nanoparticles were annealed at 450 °C for one hour to facilitate the formation. Then, the samples were characterized for their crystal structure, morphology, and optical properties using X-ray diffraction (XRD), scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDX), and UV-visible (UV-Vis) spectrophotometry, respectively. XRD analysis confirmed that the Al2O3 nanoparticles possess an orthorhombic crystal structure, corresponding to Inorganic Crystal Structure Database (ICSD) entry #98-009-4485. The average crystallite sizes were measured to be 37.36 nm, 15.47 nm, and 12.52 nm for nanoparticles synthesized at pH-9, pH-10, and pH-11, respectively. Morphologically, the pH condition affects the morphology of Al2O3 nanoparticles. The reflectance spectrum peak of Al2O3 nanoparticles in the wavelength range of 328–336 nm is observed with the band gap energy of 2.92-3.01 eV. According to these results, it is believed that the Al2O3 nanoparticles have potential applications as photocatalysts.

Abstract

This study evaluates the corrosion behavior of SS316 material welded using Inconel and 70S fillers in a static liquid lead (Pb) environment saturated with oxygen at 800 °C for 36 hours, simulating accident conditions in a lead-cooled fast reactor (LFR). Welding was carried out using laser welding (Inconel filler) and metal inert gas (MIG) (70S filler) methods, representing structural joints in the reactor. The results of scanning electron microscope (SEM) and energy dispersive X-ray (EDX) analysis showed the formation of a spinel-type oxide layer (Fe-Cr-O) in both weld areas, with the laser welding sample showing deeper Pb penetration due to the porosity of the oxide layer. In contrast, in MIG welding, the oxide layer was denser with limited Pb penetration at the spinel-matrix interface. The base metal (BM) only formed a thin layer without significant oxide, but showed lower Pb penetration. These results provide critical insights into filler metal performance under extreme conditions, supporting material selection and weld design strategies for enhanced safety and longevity in next-generation lead-cooled fast reactors.

Abstract

Surface plasmon resonance (SPR) is a well-established optical method for biosensing, allowing real-time monitoring of biomolecular interactions without the need for labeling. In this study, an SPR biosensor was designed for glucose detection by modifying a gold thin film with a self-assembled monolayer (SAM) of 16-mercaptohexadecanoic acid (16-MHA). The SAM layer was chemically activated using (1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride /N-hydroxysuccinimide (EDC/NHS), enabling covalent attachment of glucose oxidase (GOx) for selective interaction with glucose molecules. The sensor was tested with glucose solutions at various concentrations (100–300 mM) and corn syrup, which contains both glucose and fructose, to evaluate selectivity. Detection relied on measuring shifts in the resonance angle of the attenuated total reflection curve, which reflects changes in the local refractive index. The sensor exhibited a clear linear correlation between glucose concentration and resonance angle shift, indicating high sensitivity. In contrast, corn syrup produced much smaller shifts, confirming the selectivity of the biosensor due to GOx’s specificity for β-D-glucose. Performance evaluation showed higher sensitivity (S), narrower full width at half maximum (FWHM), and superior figure of merit (FOM) for glucose compared to corn syrup. These results highlight the potential of SPR for reliable and selective glucose detection in biomedical fields.

Abstract

Tea stem agroindustrial waste, rich in cellulose, hemicellulose, and lignin, presents a promising low-cost precursor for sustainable activated carbon production. This study explores the activation–carbonization approach for synthesizing porous activated carbon and evaluates its effectiveness for CO₂ capture. Chemical activation was conducted using 60% w/v KOH at different activator-to-precursor ratios (0.5:1, 1:1, and 2:1 v/w), followed by carbonization at 250°C, 350°C, and 450°C in a fixed-bed pyrolysis reactor under nitrogen atmosphere. Among all samples, A1-450 0.5 (450°C, 0.5:1 ratio) exhibited the highest CO2 adsorption capacity (1.9500 mmol g⁻¹), attributed to its high surface area (679.4 m² g⁻¹) and predominantly microporous structure. XRD analysis confirmed the presence of disordered graphitic domains with broad peaks at 2θ = 22° and 44°, while FTIR revealed abundant surface functional groups (OH, C=C, CO) essential for CO2 interactions. SEM-EDX characterization showed a heterogeneous porous surface and high carbon content (78.23%). These findings demonstrate that the activation–carbonization route is more effective than carbonization–activation in producing high-performance bio-based CO₂ adsorbents, offering a viable strategy for valorizing agro-waste into functional carbon materials

Abstract

Sheet masks are one of the most widely used beauty products to improve skin health. The increase in sheet mask usage leads to an increase in its waste, while some of the sheet masks contain synthetic fibers that are not biodegradable in the environment. Many researchers have been interested in innovating sheet masks by using natural polymer materials. Starch and cellulose were chosen because they are potentially environmentally friendly and biocompatible products. The solution casting method is used to produce sheet masks. Ginger cellulose and jicama starch were mixed, and the mass ratios of cellulose and starch are 100:0, 100:20, 100:40, 100:60, and 100:80. The addition of starch to cellulose tends to decrease the tensile strength and increase the percent elongation of the sample. The sample with a 100:0 ratio had the highest tensile strength at 34.75 MPa, while the highest percent elongation was achieved by the sample with a 100:40 ratio, measuring 4.80%. The absorption index of the sample to serum decreased with increasing starch composition. Samples with a mass ratio of cellulose to starch of 100:0, 100:20, and 100:40 exhibited better biodegradability than commercial sheet masks. Most of the samples undergo 100% biodegradation after 12 days of the biodegradation test. This research aims to develop a sheet mask made from ginger cellulose and jicama starch, which has flexible properties that allow it to conform to the shape of the face while also effectively absorbing serum or essence. This research can be used as an alternative for choosing sheet mask materials as a way to reduce plastic waste.
