IROST to Launch National Centers of "Graphene", "Clean Hydrogen Fuel" in Iran
The chairman of Iran’s Research Organization for Science and Technology (IROST) said that "National Graphene Center" and "National Hydrogen Clean Fuel Center” are set to be founded and inaugurated in Iran soon.
The IROST chairman Hassan Zamanian made the announcement at the signing ceremony of a cooperation agreement between Iran’s Research Organization for Science and Technology (IROST) and the Renewable Energy and Energy Efficiency Organization of Iran (SATBA).
“The National Graphene Center and the National Hydrogen Clean Fuel Center are being launched at the IROST. Since graphene will be the future of the world's industry and clean hydrogen fuel will be the future of the world's energy, they are important for us. As many as 130 countries and 170 research centers in the world are working on this fields,” the IROST head said.
“Since its founding, the IROST has been tasked with two duties: solving problems and removing obstacles, and producing industrial products needed in the country. This organization currently has two basic pillars that distinguish it from other research and educational institutions in the country,” he said, explaining, “We have a basic pillar called research institutes with nine research institutes.

Iranian Researcher Offers Solution for Producing More Durable, Faster Charging Lithium Batteries
A professor of Physics at Tehran-based Sharif University of Technology (SUT) in cooperation with a research group from Shanghai University in China, have offered a new formula for hybrid structure of carbon nanotubes and silicon nanoparticles as the anode of a lithium batteries.
According to a report by Iran Nanotechnology Innovation Council (INIC), Ali Esfandiar, an associate professor of Physics at Sharif University of Technology (SUT) in collaboration with a group of international researchers showed in laboratory and numerical simulation that the design of suitable functional groups on carbon nanotubes can result in better contact with the surface of silicon nanoparticles.
Despite the very high storage capacity of lithium ion in the atomic structure of silicon as an alternative to the conventional graphite anode, the large and irreversible volume change of the new silicon anodes in lithium ion batteries usually causes the physical fracture of the particle, which causes the disconnection of the conductive agent and the metal context. This unwanted phenomenon leads to unbalanced charge distribution on silicon surfaces in fast charging or low temperature conditions and ultimately reduces the battery’s capacity.
Therefore, the stable and reversible distribution of silicon in the state of lithium ion storage with good mechanical stability in order to withstand large volume change of silicon and maintain the strength and adhesive properties of the material is a big challenge.
