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).

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
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...
