Exploring Microemulsion-Prepared Lanthanum Catalysts for Natural Gas Valorisation

A continuous process for glyoxal valorisation using tailored Lewis-acid zeolite catalysts

Nanosized strontium aluminate phosphors prepared via a reverse microemulsion route

Nanosized strontium aluminate phosphors co-activated by Eu2+ and Dy3+ were prepared via a novel reverse microemulsion process. This new ynthesis technique lowered the synthesis temperature of SrAl2O4: Eu2+, Dy3+ phosphors to as low as 900 ◦C, and also reduced the particle size o the nanometer scale (around 40 nm). In the microemulsion process, the constituent cations were trapped by numerous na...

Microemulsion-mediated Synthesis of Nanosize Molybdenum Sulfide Coal Liquefaction Catalysts

INTRODUCTION In heterogeneous catalysis, the size of the catalyst is of considerable importance in that the extent of reaction is often inversely proportional to the particle size of the catalyst. As a consequence, various methods have been used to synthesize particles of large specific surface area for catalysis applications (1-3). Most of these methods are based on hydrocolloids (1) and aeros...

Polyester synthases: natural catalysts for plastics.

Polyhydroxyalkanoates (PHAs) are biopolyesters composed of hydroxy fatty acids, which represent a complex class of storage polyesters. They are synthesized by a wide range of different Gram-positive and Gram-negative bacteria, as well as by some Archaea, and are deposited as insoluble cytoplasmic inclusions. Polyester synthases are the key enzymes of polyester biosynthesis and catalyse the conv...

Simulation of Bioreactors for PHB Production from Natural Gas

Recently, many economic studies of poly(3-hydroxybutyrate) PHB production on an industrial scale, and the impact of replacing petrochemical polymers by PHB were carried out, clearly indicating that the most crucial factors to reduce the cost of producing biopolymers are allotted to the application of microbial production strains capable of high productivi...
