- MOF-Based Mixed-Matrix Membranes in Gas Separation – Mystery and Reality
Sebastian Friebe, Lisa Diestel, Alexander Knebel, Alexander Wollbrink and Jürgen Caro

In mixed-matrix membranes (MMMs), suitable microporous nanosized filler like zeolite or carbon can modify the permeation properties of a polymer. Metal-organic frameworks (MOFs) are very promising filler materials for MMMs. The chemistry of MOFs allows for covalent linkage to the polymer. MOFs can be prepared as nanoparticles and as delaminated two-dimensional nanosheets.
- Crystallization of Nano-Calcium Carbonate: The Influence of Process Parameters

Precipitated calcium carbonate can be used in many industrial applications. The influence of the process parameters on nano-calcium carbonate crystallization by carbonation of calcium hydroxide was investigated. High Ca(OH)2 concentrations and low CO2 pressures favored spherical calcite morphology.
- Cellulose Aerogel Fibers Tested on a REXUS 18 Rocket – The ACTOR Project
Björn Schulz, Tobias Meinert, David Bierbüsse, Michel Busen, Nina Körtzinger, Michael Stankowski and Gunnar Seide
Version of Record online: 27 JUL 2016 | DOI: 10.1002/cite.201600003
REXUS rocket experiments open doors for material research projects in space. The authors designed and built up an experimental setup, which allowed to examine the thermal insulation behavior of newly developed materials, such as cellulose aerogel non-woven samples, during a rocket flight at the European space center Esrange in Kiruna, Sweden.
- The Plug & Play Reactor: A Highly Flexible Device for Heterogeneous Reactions in Continuous Flow
Georg J. Lichtenegger, Vitan Tursic, Hannes Kitzler, Klemens Obermaier, Johannes G. Khinast and Heidrun Gruber-Wölfler
Version of Record online: 27 JUL 2016 | DOI: 10.1002/cite.201600013
The plug & play reactor includes exchangeable reaction segments filled with solid catalysts as well as modules for heating/cooling and mixing. Its performance is demonstrated for two model processes: a heterogeneously catalyzed esterification and a Suzuki-Miyaura coupling. The reaction progress was monitored using inline UV-vis spectroscopy.
