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).

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
