In the past nine years, I have been focusing on nanomaterial research. It was begun at 2008 when I started my Ph.D. study; I have done some research on Manganese-Zinc Ferrite (MnZn Ferrite) and Yttrium Iron Garnet (YIG) for new nanocatalyst on ammonia synthesis using magnetic induction method (MIM). This research resulted in a tremendous impact on ammonia yield which successfully increased the yield by almost 75% in lab scale experiment. A new method for ammonia synthesis using Magnetic Induction Method (MIM) was introduced. This method was synthesizing ammonia in physics manner instead of chemical manner. By using MIM, high temperature and high-pressure operation condition can be limited and in fact decreased to room temperature and ambient pressure and replaced by magnetic induction that behaves according to ortho-para hydrogen interconversion. In this project, I have won several awards such as Gold Medal on Engineering Design Exhibition by Universiti Teknologi PETRONAS (UTP), Gold Medal on ITEX Malaysia, Russian Awards on ITEX Malaysia and also Gold Medal in IENA Germany. I also published several papers in an international journal indexed by SCOPUS and two book chapter in Springer-Verlag Germany.
On 2012 I started the new project on nanomaterial for dental amalgam and human bone implant. In this case, I have granted around 250 million rupiahs by Research, Technology and Higher Education Department (RISTEK DIKTI) on Decentralization Research Grant for 3 years. I have proposed new innovation on dental amalgam using Zinc Oxide nanoparticle and replaced the usage of mercury as previous material. The results proved that ZnO nanoparticle has the same strength as mercury but biocompatible for human teeth.
On 2013 and 2014, I developed nanocomposite for human bone implant, especially on knee joint implant. It used nanocomposite ZnO and Al2O3 for the joint as a new material. The results showed that compressive strength almost 3 Gpa and this was much higher than stainless steel as the previous implant material. The simulation of mechanical strength has been obtained using Catia software.
On 2015, I have won the Learning University Award from Universitas Negeri Malang and also Bronze Medal for The Best Paper in MIGS-AGS 2015 Conference in Surabaya.
Right now (2017-ahead), I am focusing on the application of magnetic nanomaterials for catalytic converter and also the behavior of aluminum alloy under artificial aging treatment.
