Researchers at Charles Darwin College (CDU) are utilizing a state-of-the-art nanofiber fabrication facility situated on the Casuarina Campus to create fibres which are 10 to 100 occasions thinner than a spider’s silk to unravel among the urgent points the Northern Territory is dealing with.
Nanofibers are light-weight and have a diameter about 1/one thousandth of a human hair.
It has extraordinarily excessive floor area-to-volume ratio which acts like a superpower, permitting them to ship outsized efficiency in quite a few functions. This attribute means they’ve an infinite quantity of energetic floor packed right into a tiny area, enabling them to work together extra successfully with their atmosphere – whether or not that is capturing mild, absorbing impacts, or bonding with different supplies.
The fibers created from electrospinning can be utilized as in bulletproof vests, filters for water purifiers, and medical tools.
Quite a lot of supplies starting from artificial to pure supplies together with collagen, keratin and gelatin might be spun as nanofibers utilizing electrospinning method, which includes a liquid droplet being stretched and elongated to kind the fibres underneath a exactly managed electrical area.
CDU College of Science and Know-how Lecturer in Mechanical Engineering Dr Naveen Kumar Elumalai is main a workforce testing the power and skill of nanofibers to see how they can be utilized in on a regular basis conditions.
Of explicit curiosity to the workforce is methods nanofibers may help within the defence trade, producing hydrogen from water splitting utilizing daylight, and in industrial filtration.
Dr Elumalai stated vests and different protecting clothes might be constituted of electrospun nanofibers.
“Kevlar vests and different protecting clothes which our police and defence pressure put on are presently fairly heavy and lack breathability, which isn’t preferrred right here within the NT,” Dr Elumalai stated.
“Utilising nanofibers will assist to make the vests stronger with out rising the burden. Which means they are going to provide larger safety for wearers towards issues corresponding to bullets and shrapnel with out making them hotter, that is for certain a win-win.
“We do must do extra analysis to find out which substance can be probably the most useful, however we hope to work with the defence trade significantly right here within the NT on the event of those good textiles.”
One other space the place nanofibers have the possibility to generate large alternatives within the NT is with air and water purification.
That is vital in distant First Nations communities which frequently undergo from poor reliability and consuming water high quality which may have circulate on results om financial and well being outcomes.
“We’re trialling using nanofiber expertise on the subject of air and water purification because the nanofibers might be fashioned to make a mesh like substance which may help to cease micro organism from coming into the water or air and filters out contaminants,” Dr Elumalai stated.
“This might actually be transformative on the subject of the well being and longevity of our communities and is price efficient as nicely.”
In an thrilling improvement, Dr Elumalai’s workforce can also be exploring how nanofibers can be utilized to generate clear power. They’ve created particular nanofibers that, when dispersed in water and uncovered to daylight, can cut up water molecules to supply hydrogen.
“This expertise is especially promising for Darwin and the Northern Territory,” Dr Elumalai defined.
“It may assist tackle our power wants utilizing simply water and daylight, with out the necessity for complicated programs. Think about having the ability to produce hydrogen gasoline instantly from water – it is a game-changer for sustainable power manufacturing in our area.”
For Dr Elumalai, who in 2022, 2023 and 2024 was recognised amongst the high two per cent of scientists globally for his work by Stanford College, making a long-lasting impression right here within the NT and past is paramount on the subject of this work.
“I’ve all the time been intrigued by how issues work in nature, and I’ve a ardour for exploring issues intimately,” Dr Elumalai stated.
“I’m captivated with clear power or sustainable supplies and associated functions that may allow the well-being of the people and the atmosphere.
“I look ahead to furthering our analysis and dealing with trade teams to implement nanofiber expertise.”
