Presenting paper at ICAMST 2013

Srie Muljani, Zarra Miantina Putri and Ni Made Intan Putri Suari presented papers on International Conference on Advanced Materials Science and Technology (ICAMST 2013) held in Yogyakarta, Indonesia on 17-18 September 2013. Srie presented a paper entitled: “Synthesis of mesoporous silica from Dieng geothermal sludge, Indonesia.” This work is an effort to utilize geothermal sludge, solid waste from geothermal power plant, into an economically value-added materials. Mesoporous silicas have many potential applications including adsorbent, catalyst host, filler, column chromatography, etc.

Zarra talked about “Preparation of sulfonate-grafted silica/chitosan hybrid membrane for proton exchange membrane.” This work is dealing with development of a facile method to prepare membrane to substitute the expensive proton exchange membrane. Intan presented a paper on¬†“Coating of steel with nanosilica by pulsed direct current electrophoresis for corrosion protection.” Using pulsed direct current, nanosilica can be deposited evenly on steel surface. This makes the layer can behave as good corrosion protection of steel against its environment.
