- Segmented Flow-Based Multistep Synthesis of Cadmium Selenide Quantum Dots with Narrow Particle Size Distribution
Viktor Misuk, Maxim Schmidt, Sandra Braukmann, Konstantinos Giannopoulos, Dominik Karl and Holger Loewe

Quantum dots are nanocrystalline semiconductors that differ greatly from their bulk counterparts. To obtain CdSe quantum dots with a narrow size distribution, a two-step procedure was applied, in which CdSe seeds were synthesized in a separate process prior to the nanoparticle growing procedure. The seeds were mixed into the growing solution-containing droplet by coaxial injection.

Very dense tungsten powders simulating nuclear fuel particles were coated by silicon from silane using fluidized-bed chemical vapor deposition in a reactor with reduced diameter. Fluidization of such particles could be reached, but with non-optimal gas-solid contact due to their high density. Conditions were found to form 0.5 µm thick continuous silicon layers on the powder surface.
- Fabrication of a Chitosan-Coated Magnetic Nanobiocatalyst for Starch Hydrolysis

Magnetic nanoparticles (MNPs) can serve as a superior solid matrix for enzyme immobilization. Covalent immobilization of α-amylase onto chitosan-coated MNPs was optimized by response surface methodology. This nanobiocatalyst with high temperature and pH stability can be applied in industries for economical and highly efficient starch hydrolysis.
- Process Intensification Tools in the Small-Scale Pharmaceutical Manufacturing of Small Molecules
Aleksandar Mitic and Krist V. Gernaey
Article first published online: 29 MAY 2015 | DOI: 10.1002/ceat.201400765
Promising tools for accelerating slow chemical reactions in organic synthesis in order to achieve process intensification are reviewed with the focus on microwave radiation, meso-scale tubular reactors, microreactors, and ultrasounds. Applications of such tools for producing small molecules in the pharmaceutical industry are discussed and illustrated with examples.
