Co-precipitation synthesis, physical and magnetic properties of manganese ferrite powder

Magnetic manganese ferrite powder was synthesized via chemical co-precipitation techniques using metallic chlorides of manganese and iron. Sodium hydroxide (NaOH) base was used as precipitant agent. The calcinations were performed at 600°C for 5 h. The structural investigation of the prepared sample was performed with X-ray diffractometer (XRD) and scanning electron microscope (SEM). The crystallite size was 26.53...

Development of ordered and disordered macroporous silica from bagasse ash

Silica from bagasse ash was nanostructured with templating concept, these resulted into ordered and disordered nano pores in the silica. The average pore widths were between 220.87 and 537 nm. These pores were classified as macro pores. The macro porous silica developed can be applicable in sensing, selective filtration, catalysis, drug delivery and membrane.   Key words: Silica, templating concept, macro...
