This week, University Putra Malaysia's team unveiled their latest inventions and products at the 34th International Exhibition of Inventions, New Techniques and Products in Geneva (April 2-6, 2008), also known as the World's Largest Market-Place for Inventions.
This research is on a new technique for significantly reducing the catalyst particle to nanoparticle size so that the surface area is greatly increased. This significant breakthrough is important because chemical reactions happen on the surface of catalyst. Therefore this allows the catalyst to operate at lower temperatures, higher yields and shorter preparation time
TITLE: Nanoparticle of Vanadium Phosphate Catalysts for Selective Oxidation of n-Butane to Malice Anhydride
All chemical industry process reacts on the surface of catalyst. Therefore with the invention of this new method having significantly high surface area (> 50 m2g-1) by decreasing the particle size to nanoparticle (first time in the world) of the catalysts and consequently enhance release of the oxygen species from the catalyst for VPO catalyst will provide a high active site for the reaction to be occurred. This is very interesting and extremely potential commercialized for selective oxidation of light alkanes.
The active catalyst has linear relationship between light alkane conversion with the catalyst surface area. This implies that the surface structure of the activated catalysts are very similar and the activity differences are just due to the higher surface area VPO catalyst having a higher number of active sites per unit mass of catalyst. This high surface area catalyst particular advantage of higher surface area catalysts is that the can operated at lower temperature which leads to an enhanced selectivity and yield in product being obtained also potentially use for other light alkanes oxidation, shorter preparation duration for this new method (from 26 to only 8 h).

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
