Abstract

Chitosan-pectin membranes are biodegradable polyelectrolyte complexes, derived from biomaterials, with good stability for drug delivery applications. This study investigates the potential of these membranes to encapsulate quercetin, a flavonoid known for its therapeutic properties but limited for its low solubility, poor bioavailability, and rapid elimination. The membranes were synthesized using a 1:1 (w/w) chitosan-to-pectin ratio and loaded with quercetin via solvent evaporation. Characterization using FTIR confirmed the presence of OH, C=O, and NH groups; XRD indicated semi-crystalline structure; and SEM revealed a uniform, porous morphology. The maximum quercetin loading efficiency reached 82.43%, with the highest release (90.39%) observed at pH 1.2, following first-order kinetics. The resulting membrane was thin, brown, homogeneous, and tear-resistant, demonstrating its potential as a controlled drug delivery matrix for quercetin

Abstract

The use of steel panels in conventional bulletproof vests is no longer relevant to current needs. In addition to being heavy, troop flexibility is disrupted. It is necessary to develop lighter and more reliable composite panels. The purpose of this study was to determine the ability of organosilica resin composite panels that were given variations of 5, 7 and 9 layers of woven fiberglass to withstand 9 mm caliber bullets using the NIJ-0101.06 Standard. The results of the firing test showed that the bullets were held back in the 7th and 9th layers. This result shows that this composite is a worthy candidate to replace conventional steel panels in bulletproof vests.

Abstract

This study explores the effect of surfactant use, namely Sorbitan Monostearate (Span 60) and Polyethylene Glycol 400 (PEG 400), on the physical and mechanical characteristics of bitumen modified with multilayer plastic. The focus of this study is to improve the compatibility between bitumen and multilayer plastic, which often have incompatible properties, thus affecting the performance of bitumen. Methodology applied includes the preparation of bitumen samples modified with varying surfactant concentrations, followed by microscopic analysis to assess particle dispersion and distribution. The results showed that the addition of surfactants significantly improved particle dispersion, with smaller particle sizes and more even distribution. Ductility tests showed that bitumen modified with surfactants had better flexibility compared to conventional bitumen, while penetration tests showed improved elasticity properties. These findings indicate that the use of surfactants in bitumen modification can improve the physical and mechanical properties of the material, providing potential for wider applications in the construction industry. Further research is recommended to explore other surfactant combinations and their impact on bitumen properties under various environmental conditions.

Abstract

Synthesis and Characterization of LaF3:Ce Scintillator Material.Synthesis and characterization of the LaF3:Ce scintillator have been carried out. Synthesis was carried out using the co-precipitation method. In this study, the raw materials used were NaF, LaCl3•7H2O, and Ce(NO3)3•6H2O with ethanol and distilled water as a solvent; while surfactants were used oleic acid. In this study, the compound LaF3:0.2Ce was synthesized. The sample was characterized by using an X-Ray Diffractometer (XRD), a Scanning Electron Microscope (SEM), and a Spectrofluorometer. The analyzed data showed that the 82.6 weight fraction of LaF3:0.2Ce phase has precipitated accompanied by the formation of NaCl and C2Ce phases of 5.1 and 12.3 weight fraction, respectively. The NaCl phase is a by-product of the chemical reaction: xLaCl3•7H2O + zCeCl3•7H2O + 3NaF → LaxCezF3 + 3NaCl + 7H2O which could be removed from the precipitate solution by an appropriate separation method, while the C2Ce one appeared as a result of heating the sample at 400ºC. The LaF3:Ce scintillator sample shows the phenomenon of a bluish glow with a lifetime, t = 6 × 10-10 seconds even in the presence of a foreign phase. The existence of NaCl and C2Ce as a local environment still makes LaF3:0.2Ce has normal lifetime characteristics.

Abstract

The addition of materials to pile pipe at low temperatures is very challenging. Thereby, an optimum operating level is needed to produce a quality coating. Furthermore, 2-methylimidazole (2MI) was added into a phenol-formaldehyde, glycidyl ether polymer fusion bonded epoxy (FBE) coating at different concentrations of 1, 2, and 3 %wt. Thermal analysis was then carried out using differential scanning calorimetry (DSC), where the addition of 2MI decreased the curing temperature to 134.76°C due to the reduced activation energy. Potentiodynamic polarization showed the best corrosion rate of 0.00991 mm/year with a current density of 0.847μA/cm2 after adding 1 %wt 2MI. Electrochemical impedance spectroscopy (EIS) was carried out to determine the charge transfer resistance and maximum coating capacitor capacitance after adding 1 %wt 2MI, namely 9.9 kΩ and 8.45×10-5 F, respectively. The cathodic disbondment test (CD-Test) showed that the disbondment radius of the coating under the influence of the cathodic protection current was 4.32mm. Mechanical analysis by pull-off adhesion test showed a value of 7.28 MPa after the addition of 2MI 2 %wt but decreased to 6.63 MPa at 3 %wt. Therefore, the optimum addition is 1 %wt 2MI for low-temperature applications of 170 –175°C in piles with high coating performance and compliance with predetermined standards.

Abstract

This study utilize vegetable oil derivatives as a polyol in polyurethane. A modification of epoxy using polyurethane was done using ester derivative of vegetable oils as polyols, which was polyethylene glycol monooleate (PEGMO). The PEGMO was synthesized via an esterification reaction. The synthesis of polyurethane-modified epoxy using polyethylene glycol monooleate ester (PME-PEGMO) was conducted by reacting epoxy, tolonate and PEGMO. Analysis results of FTIR and H-NMR showed a new absorption peak derived from the urethane bond. The mechanical and thermal properties were characterized by a universal testing machine (UTM) and thermogravimetry analysis (TGA), respectively. According to the analysis results, it is shown that the addition of polyethylene glycol monooleate ester-based polyurethane on epoxy improved the mechanical properties of the epoxy, from 69.61 kgf/cm2 to139.80 kgf/cm2. However, it decreased the thermal stability of the epoxy. At 500°C, the mass of epoxy was remaining 28%, while the PME-PEGMO was only 13%.

Abstract

Glass fiber/epoxy composite was developed and used widely in manyapplications. Development on fiber and matrix of composite material was done to improve itsproperties. Improvement of the composite’s matrix can be done/by adding a modifier. Silicone resinis one kind of modifier that can be added to epoxy to improve its properties. Silicone resin willimprove the thermal stability of epoxy, but the effect on mechanical properties, especially whencombined with glass fiber, has not been done. In this study, a composite of glass fiber/epoxy with 0,10, 20, and 30 weight-% silicone resin addition was tested by compressive and flexural loadingmethods. Compressive strength and maximum strain tend to decrease with the increase of siliconeresin added. The highest compressive strength and strain were reached by a glass fiber and epoxycomposite without any modification at the value 240.63 MPa and 0.5%. Flexural strength willdecrease, but maximum strain will increase when more silicone resin is added to the matrix on theflexural test. The biggest flexural strength at 293.73 MPa was possessed by the composite withoutfurther modification, and a maximum strain of 5% was owned by the composite with 20% and 30%silicone resin addition.

Abstract

The aim of this research is to synthesize porous carbon black microspheres from palm oil black liquor through an in-house spray pyrolysis system. The in-house spray pyrolysis (SP) system was developed using a horizontal furnace. To test the developed SP equipment, the temperature profiles within the developed spray pyrolysis chamber were examined at 3 different setting temperatures (800, 900, and 1000 °C). These temperatures were also applied for synthesizing the carbon black microspheres, with and without nitrogen as carrier gas. The morphology of carbon black produced by using SP equipment was tested by a 3D Optical Microscope and FE-SEM. The optimum temperature obtained in this study is 1000 ºC according to the characterization of carbon black microspheres produced. The FE-SEM analysis indicated the presence of spherical carbon having microstructures. This indicates that the in-house spray pyrolysis machine has been successfully developed for synthesizing carbon black microspheres.

Abstract

This study aimed to create and examine plastic scintillators made from a polystyrene matrix, which are widely used in radiation detection due to their favorable properties such as rapid decay time, low cost, resistance to moisture, and ease of fabrication. The scintillators were doped with p-terphenyl (PTP) and 1,4-bis[2-(phenyloxazolyl)]-benzene (POPOP) using an injection method with an extruder machine. The materials were then characterized using various techniques. Fourier Transform Infrared Spectroscopy (FTIR) revealed the presence of aromatic chains which are essential for the scintillation process. Differential Scanning Calorimetry (DSC) analysis showed stable thermal properties with a glass transition temperature of approximately 100ºC. Scanning Electron Microscopy (SEM) showed that the surface of the polymer is amorphous with small bumps and protrusions likely caused by the PTP and POPOP dopants. The optical evaluation indicated that the sample could absorb UV photons up to 340 nm and emit photons in the wavelength range of 400-500 nm with a peak at 421 nm. Gamma spectra analysis indicated that the plastic scintillators performed well in gamma detection and could be used in a Radiation Portal Monitor (RPM).
