Comparative Adsorption Studies on Raw Rice Husk, Acid Leached Rice Husk and Base Leached Rice Husk by Using Methylene Blue as Dye
Abstract: Current methods for removing dyes from wastewaters are costly and cannot effectively be used to treat wide range of such wastewaters. This work describes the use of raw rice husk (RRH), acid-leached rice husk (ALRH) and base-leached rice husk (BLRH) as adsorbents for decolorization. Characterization of raw rice was done by powder X-ray diffraction (P-XRD) analysis, surface area analysis and scanning electron microscopy. Raw rice husk was collected directly from …

Exploring Abrasive Flow Finishing of 3D Printed Mesoscale Passage
Abstract: 3-D printed parts and components have gained wide applicability which continues to increase day by day. However, due to the very nature of 3-D printing process, i.e. layer additions, outer surfaces are subject to poor finishing. Finishing 3-D printed parts is thus a necessity if they are to be used for prototyping or functional purpose. But, finishing remains a challenge, especially if the part contains passages that lie within and …
