Realising the importance of clean water for more than 27 million people in Malaysia, two USM students successfully produced a material which is able to absorb heavy metal from industrial waste water.
The product, called “mobilised Yeast” was created by Eka Anggraini Azuardi and Nazira Khabibor Rahman – both final year student from the USM Chemical Engineering Research Centre.
The product, is not only effective but also more economical, compared with the current method.
According to Eka Anggraini, the product was invention using the bio absorption method – by changing yeast which are used in food, as heavy metal absorption agent, in the waste water.
The yeast is produced in the shape of beads in cream colour. The beads would be mixed in the waste water which is to be treated.
When the heavy metal is absorbed, the beads will change to a blue-ish colour. The whole process will be repeated to ensure that the waste water is completely free of heavy metal, said Eka Anggraini.
The research started since June 2007 as the two students’ final year project.
Eka Anggraini said through the research and laboratory tests, “Immobilised Yeasts” showed very encouraging effectiveness.
Heavy metal consumed by our human body would not be able to flush out. It will remain in the body and may cause very serious health problems.
If the waste water does not go through proper treatment, it will have negative effects on human and other living creatures on the earth, said Eka Anggraini.
She added that, to date, there are only three ways to treat waste water, namely ion changing, membrane technology and abstractive chemical process.
Nevertheless, these methods are very expensive and often, bring negative consequences to the environment.
Optimistic with the research results, Eka Anggraini said “Mobilised Yeasts” also has the potential to be expanded to treat water for various other purposes.
“Mobilised Yeasts” is one of the 145 products taking part in the National Level Research and Innovation Competition 2008 in USM.
The competition lasted three days from 20 May 2008.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
