Preliminary Study of Microwave Irradiation Towards Oil Palm Empty Fruit Bunches Biomass

In this study, torrefaction via microwave irradiation was introduced towards oil palm empty fruit bunches (EFB) samples. The samples of 10 g was fed into the quartz type crucible inside the microwave with the power input limit to 385 W. Continous nitrogen up to 50 ml/min were induced and promoted the non oxidative atmos...

Potential of Fabricated Light Foamed Concrete in Reducing Radon from Building Material

Three of Light Foamed Concrete (LFC) have been obtain by using different formula of Cement:Aggregates. The brick was locate into a closed Perspex box and the net of 222Rn concentration level have been measured for 5 consecutive days. The results show the LFC 3 has produced the lowest of net 222Rn concentration level in...

A New Invention of Thermal Pad Using Sol-Gel Nanosilver Doped Silica Film in Plastic Leaded Chip Carr

Thermal pad is new technology in the world that been used in PLCC in order to reduce junction temperature to the minimum level in electronic components. Thermal Pad was made by using nanosilver as main material. nanosilver silica films were applied on PLCC using a sol-gel process and heat-treated at different temperatu...
