Science & Research IAU Students Unveil Their Applied Researches

Science and Research Islamic Azad University has held an Exhibition on Research & Technological Achievements in order to be pioneer in domestic production and help “Resistance Economy”.

According to an ISCA report, as one of the notable branches of Islamic Azad University, Science and Research IAU has been active for more than 3 decades and gained many achievements in various fields of science and research. Amir Hossein Ehsani unveiled his 3D printer which can be compared to foreign competitors.

Armin Faridi, Master of Science in Mining Engineering, designed a device which is able to treat Industrial waste water using agricultural waste, waste produced as a result of various agricultural operations.

As he explained about his achievement, agricultural wastes of each region must be optimized with chemicals first and then place them in industrial wastewater to treat them. He added that the technology will reduce expenses as well as create relationship between artisans and farmers.

Leila Fekri, post-PhD physics from Plasma Physics Research Center, presented her patent which is a way of making paper supercapacitors for electricity storage, according to a new study published in the journal Heliyon. At one sheet thick, these new supercapacitors can bend, fold, flex, and still hold electricity.

The term ‘supercapacitors’ is reserved for devices that hold over 10 times as much energy per unit volume as a traditional capacitor, and that can charge and discharge quickly. Paper supercapacitors are lighter and cheaper than other types and those developed by lead author, Dr. Leila Fekri Aval’s group are more flexible than earlier paper supercapacitors, giving them a whole new range of potential uses. "In the near future, the industrial and homemade applications for these types of supercapacitors will increase and the cost reduce, making them available to the public," explains Dr. Aval.

The team of researchers investigated the structure of commercial supercapacitors and produced one that uses one sheet of carbon nanotube paper with different layers. They used barium titanate to separate the layers, which is more economical than any alternative compounds. The new paper superconductors can store energy efficiently even if they are rolled or folded.

The potential applications of these new devices are vast: Medical implants, skin patches, wearable tech, and novel large-scale energy storage for domestic and commercial transport and smart packaging. Imagine, for example, using a computer tablet that can roll up and fit in your pocket or a phone that is part of your coat, or charging your phone with a battery that is part of your clothing.

Dr. Aval anticipates that the commercial and domestic applications of these supercapacitors will soon increase and the cost decrease, so the technology will become available to the mass market. "Energy is our most important challenge in the future," said Dr. Aval. "It is important to build a device that stores energy, has high power and energy density, but at a low cost. This is what inspired our research into paper supercapacitors."

Producing electricity from algae, various medical achievements and producing paper from peanut skins and Luffa were some other significant achievements of Science and Research IAU students presented at the Exhibition on Research & Technological Achievements.
