introduction: glass-ionomer cements (gics) are one of the most important dental restorative biomaterials. the aim of this study was to synthesize glass-ionomer‒silk fiber composite and evaluate the effect of adding natural degummed silk fiber on the bioactivity and the ability to release fluoride by glass-ionomer cement. materials and methods: in this study, commercial fuji ii glass-ionomer cem...

Monitoring the gases released during breathing or via skin has gained significance towards diagnosing diseases. In this study, a sensor chip capable of detecting nonanal gas, which is known to be marker lung cancer, was developed. The gas detection agent used vanillin, underwent aldol condensation with in presence basic catalyst, resulting formation an unsaturated aldehyde. Porous glass as reac...

In this study, various treated, untreated, and treated kenaf/glass fiber composites were fabricated using epoxy resin. A portion of kenaf fibers subjected to treatment with alkali, sub-portion was taken for benzoyl peroxide potassium permanganate prior composite fabrication. This on the material undertaken achieve improved modification interface between matrix bond. glass used enhancing mechani...

This study aims to observe the impact of fiber lengths and NaOH treatment on tensile properties composite materials made from borassus polyester matrix. used fibers fruit, Wax Mirror Glass, Polyester Alkali (NaOH). The was carried out by soaking in a 15% solution for 2 hours. length this were short (<1cm) long (>8 cm). composition number matrix calculated based volume fraction test spesim...

Glass, in contrary to crystals, lacks long-range translation symmetry so that standard experimental scattering methods such as X-ray or neutron scattering must be improved and/or sophisticated both theoretically and experimentally to obtain comparable results. However, scattering experiments are not able to provide 3D image of the structure but only its 1D projection resulting in the so-called ...

This paper demonstrates the feasibility of replacing the metal coil spring with the composite coil spring. Three different types of springs were made using glass fiber, carbon fiber and combination of glass fiber and carbon fiber. The objective of the study is to reduce the weight of the spring. According to the experimental results the spring rate of the carbon fiber spring is 34% more than th...

The creep behavior of basalt fiber reinforced epoxy (BFRE) and glass fiber reinforced epoxy (GFRE) composites was studied through tensile testing at high temperature. To study the effect of reinforcing epoxy, the micro glass powder (MGP) was added at various volume percentage into the epoxy resin in BFRE composites. The initial strain for all the specimens were evaluated and compared with each ...

Brittleness, which was the inherent weakness in High Strength Concrete (HSC), can be avoided by reinforcing the concrete with discontinuous fibers. Reinforcing HSC with more than one fiber is advantageous in an overall improvement of the mechanical performance of the composite. In this experimental study, Hybrid Fiber Reinforced High Strength Concrete (HyFR-HSC) mixes were formed by blending si...

The objective of this study was to evaluate the effect of fiber treatment on both morphological and single fiber tensile strength of empty fruit bunch (EFB). EFB fiber was treated with boiling water, 2% sodium hydroxide (NaOH) and combination both NaOH and boiling water. Fiber morphology was characterized by scanning electron microscopy (SEM). Thermogravimetric analysis (TGA) was further used t...
