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.
