Abstract

Research has been carried out with the aim of studying the formation of functional groups of a composite of silver silica (Ag/SiO2) based on rice husk silica and silver nitrate (AgNO3) as a precursor using the sol-gel method. Variations in the concentration of AgNO3 used were 0,3M; 0,5M; and 0,7 M with a thermal temperature of 850 °C. The results of Fourier transform infrared spectroscopy (FTIR) showed the formation of Si-O-Si, Si-O, and O-N-O functional groups which were the result of AgNO3 residue indicating the presence of Ag.

Abstract

In this study, the characterization of the carbosil asphalt composite was carried out with a composition variation of 1:9; 1.5:8.5; 2:8; 2.5:7.5; 3:7 and the ratio for pure carbosil without the addition of asphalt. Carbosil is obtained from rice husk waste by using the pyrolysis method. This research was conducted to determine the effect of temperature on the microstructure, structure and functional groups of carbosil asphalt composites. XRD analysis obtained that the phase formed from each composition variation was an amorphous phase. The DTA/TGA analysis shows that there is a change in energy due to the addition of heat, which is indicated by the presence of mass shrinkage in the sample. Compressive strength results indicate that the strength of the carbosil asphalt composite with different material compositions affects the resistance to cracking.

Abstract

Research has been carried out aimed for looking effect of mixing Ethylene Glycol (EG) and propylene glycol (PG) on optical characteristics of silver nano wire (AgNWs) which synthesized using the polyol method. Synthesis was carried out for ± 5 hours on temperature of 130 oC inside erlenmeyer flask. The material used are silver (Ag) which is obtained from AgNO3, mixed solution of EG/PG with a concentration ratio of 100:0%; 75:25%; 50:50%; 25:75%; and 0:100%, FeCl3.6H2O, and capping agent in the form of Polyvynil Phyrolidone (PVP). The optical characteristics of AgNWs were observed through UV-Vis, FTIR, and length distribution through optical microscopy. The results of UV-Vis analysis showed four absorption peak at a wavelength of around 340, 350, 360 and at a wavelength of 390 nm as well as a change in the absorbance value. While the optical microscope test results also show that the length of the AgNWs increased on sample EG/PG 75:25% and 50:50%. Based on these results, it can be concluded that the mixing of EG and PG can affect the optical characteristics of AgNWs.
