Study on the effect of zeolite rice husk particles on polysulfone membrane
Rice Husk Zeolite Type Y (RHY) particles were prepared under static hydrothermal conditions by dissolution of sodium hydroxide (NaOH), sodium aluminate (NaAlO2) and amorphous silica obtained from rice husk ash (RHA). The RHY/polysulfones (PSf) membranes incorporated with RHY particle at different …

Photocatalytic degradation of palm oil mill secondary effluent (POMSE) using zinc oxide nanoparticles
… presence of ZnO-PEG nanoparticles and its physicochemical is still limited. Therefore, this study reports on the comparison of physicochemical properties between the ZnO nanoparticles in presence of the different type of capping agent Commercial ZnO, ZnO-PEG and ZnO-PVP, photocatalysis of POMSE by …

The effect of chemical treatment, fibre length, fibre content and injection moulding parameters to uv irradiation resistance of oil palm fibre reinforced composites
There are many types of polymer used in engineering materials expose to UV irradiation, such as automotive parts (car body, bumper, dashboard etc.) which can cause material degradation. Some polymers are used in pure polymer and some of them in composite material. This study has investigated the …
