Magnesium (Mg) has a great potential to be used in various field of work since it is lightweight and has low density properties. However, its application is limited due to its poor properties for Mg has a relatively low strength. Improvement is made by mixing Mg with calcium (Ca) as composite element for it is lightweight and non-toxic. In this research, Mg is prepared with different weight percentage (0, 0.5, 1, 1.5, 2 wt. %) of Ca with pure Mg as reference prepared by powder metallurgy (PM) method to study the mechanical properties. Morphological analysis carried out by optical microscope shows increase grain refinement with the increase of calcium content in Mg-Ca composites. The phase transition upon addition of Ca is determined using XRD method detects formation of Mg2Ca. Range from 1.78 g/cm3to 1.83 g/cm3, the density of each sample composite increase. While porosity profiles show inverse characteristics upon addition of Ca. Microhardness strengths also intensifies up to 193.20 MPa as more Ca content added in.

Having the benefit of lightweight and low density makes magnesium (Mg) a good element with high potential to be used in various field of work. Yet, its application is limited for Mg is relatively low in term of strength. Hence, calcium (Ca) is chosen to be mixed with Mg as additional element for it is lightweight and non-toxic. In this research, Mg is prepared with different weight percentage (0, 1, 2 wt. %) of Ca via powder metallurgy (PM) method. The effect of sintering was investigated by focusing on the microstructure and properties of sintered sample. The samples were sintered at two sintering temperature (500 and 600 °C) in argon atmosphere. Morphological analysis carried out by optical microscope shows increase pores refinement with the increase of sintering temperature together with calcium content in Mg-Ca composites. Results show that the grain size and hardness of the samples increase as sintering temperature increase.

In this paper, graphene oxide (GO) was doped into SU-8 polymer to examine the functionalities of polymer waveguide material via dopant inclusion. In material preparation, step by step processes starting from cyclopentanone mixing will be explained. It is shown that doped material's refractive index can be tailored by having different weight percentage of GO. Finally, a single mode ridge waveguide loss of GO doped SU-8 has been characterized to be 1.9 dB/cm at 1550 nm wavelength.

Fabrication And Characterization

The purpose of this research was to fabricate the particle board from the coffee husk. The coffee husk from Chumphon province of Thailand was collected, prepared and separated into four groups such as outer husk, inner husk, the mixture of inner and outer husk and husk from the milling process. The coffee husk particle sheet was formed by the compression molding with the heater. Then the coffee husk particle sheets were the mechanical properties testing. The results showed the coffee husk particle sheet from milling process pass the Thai industrial standard (TIS.876/2547). However, the results of swelling and water absorption indicated that all the coffee husk sheet were not passed the TIS.876/2547. The effect of coffee husk particle size on mechanical properties was clarified. The coffee husk particle sheet from the particle size of 2, 4 and 6 mm was mechanical testing and follow TIS.876/2547. The coffee particle size of 2 mm showed the passing the standard. Moreover, the effect of isocyanate adhesive on mechanical properties was investigated. The weight percentage range of isocyanate adhesive on coffee husk from 7 to 13 %wt was carried out. The weight percentage of 9, 11 and 13 showed according to TIS.876/2547. From the experiment indicated that the coffee husk could be applied to the wood particle board industrial.

Porous F-75 (Co-Cr-Mo) was produced by powder metallurgy technique. F-75 powder was mixed with space holder and compacted using different pressures (300 MPa, 350 MPa, 400 MPa, 450 MPa). The green samples were sintered at 1150 °C in a tube furnace under argon atmosphere. Sintered samples were examined in terms of bulk density, porosity, hardness and pore size. Microstructural analysis was carried out using a scanning electron microscope (SEM). Microstructure analysis showed that pore sizes and pore shape were influenced by different compaction pressure. The hardness of the samples increased as compacting pressure increased. Density and porosity remained constant at certain level.
