Aminuddin Muhamad Baki and four other young researchers, supervised by Professor Suhaimi Abdul Talib, of UiTM, found that having more organic content in sludge will generate more methane. Biogas composed of methane and carbon dioxide is a by-product of anaerobic bacterial decomposition of organic waste.
The organic waste content of municipal garbage and sewage means that they are important sources for biogas production. The methane content in biogas enables it to be used as engine fuel as well as enabling it to be converted into heat and electricity. An experimental study was completed that examined the relationship between the organic content of sludge and methane generation as the sludge progressed through mesophilic anaerobic digestion.
This study examined the organic content in sewage, represented by Biological Oxygen Demand (BOD) and Total Suspended Solid (TSS), in order to: (a) quantify the biogas and methane generation from sewage sludge; (b) determine the relationship between organic content and volume of methane; and (c) determine the pressure of biogas and the relationship between sludge volume and volume of biogas. It was found that there is potential for methane generation during anaerobic digestion even with a small volume of sludge.
The quality of sludge for methane generation is subject to the characteristics of the sludge. The organic content represented by BOD and TSS was measured in accordance to APHA standard methods (1998). Tests were conducted on wastewater from two treatment plants: the College of Mawar, UiTM, and IWK WWTP Section 7, Shah Alam. It was found that higher organic content in sewage sludge produced a higher volume of methane.Contacts:

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
