Self-healing coating surfaces and tamper-evident security are two of the many benefits that your products can achieve by incorporating microencapsulation more
While plastics recycling is not new science, current processes don't make it economically worthwhile-- waste plastics get "down-cycled" into lower grade, less useful material. It's a challenge that continues to be an obstacle in tackling a growing global pollution crisis in single use plastics. A mu more
Chemists at the Leibniz Institute for Catalysis in Rostock were able to observe the molecular functioning of the catalyst in a redox reaction and identify important intermediate steps. For this purpose, they coupled, for the first time worldwide, four highly modern measuring methods that work in dif more
Palladium catalysts help synthesize key chemicals for many industries. However, direct reaction of two basic reagents, aryl halides and alkyllithium compounds, remains a challenge. Now, a team of scientists have found that a catalyst containing YPhos-type ligands can mediate this reaction even at ro more
Chemist Xile Hu is awarded the National Latsis Prize 2017, Xile Hu is Professor of Chemistry at the Swiss Federal Institute of Technology in Lausanne (EPFL). He is honored for his impressive scientific career and outstanding research on the fundamental understanding of catalysis. more
With over 25 years’ experience in the construction of pressure vessels behind it, Berghof is offering an innovative device concept for many types of applications in research and development laboratories. Chemical reactions, which take place under tem more
In contrast to Schwesinger type phosphazene N-superbases the compounds presented herein exhibit even more basicity more
While the technique has gained increased popularity in recent times, the principal of in situ reaction monitoring dates back to 1961 when Farenfort introduced a new method of measurement that today is called Attenuated Total Reflectance (ATR). The co more
How different factors can affect how quickly a reaction happens is a common topic in the chemistry curriculum. This graphic serves as a convenient summary for teachers and students alike of what these different factors are, and how and why they affect the rate of a reaction. However, it’s not only o more
The dramatic change in electrochemical behavior of nickel (oxy)hydroxide films upon incorporation of Fe ions provides an opportunity to establish effective electrocatalyst design principles. We characterize a photochemically deposited series of Fe–Ni (oxy)hydroxides by X-ray absorption spectroscopy more
MnOx/TiO2 (MnTi) and Nd-modified MnOx/TiO2 (MnNdTi) were prepared via a coprecipitation method. The used samples were obtained by exposing the fresh catalysts to 50 ppm SO2 stream at 210 oC for 3 h and 6 h, respectively. Comparative investigations were performed on the fresh and used catalysts to id more
MFI Zeolites exchanged with various cations have gained a great deal of attention as catalysts. Increase in the ion-exchange capacity of zeolites can improve their catalytic properties by introducing more active sites; however, the ion-exchange capacity of MFI zeolites is limited by maximum aluminum more
Optical active substances made from chiral catalysis form the basis of many drugs. Expensive precious-metal catalysts are required for the chemical production, which due to their thermal instability decompose at high temperatures and can therefore only be used once. The innovative process of DexLeChem GmbH makes it possible for the first time to use these precious-metal catalysts made from rhodium, ruthenium or iridium more than once, without modifying them. At the same time, reaction occurs in aqueous solutions instead of mineral-oil-based solvents, which increases the sustainability of the process. This is a milestone in catalysis and a real opportunity for the pharmaceutical industry. more
A combination of dark-field microscopy and electrochemistry can make individual nanoparticles in a liquid medium visible. The technique is suited to determine the activity of catalysts during their use. more
For the first time, an efficient catalyst for palladium-catalyzed C–C bonding between aryl chlorides and alkyl lithium compounds has been found. This reaction enables simpler synthesis routes for important products, such as pharmaceuticals, while avoiding much salt waste. more
