    A crystallization elution fractionation (CEF) model describing the combination of the separation powers of temperature rising elution fractionation (TREF) and dynamic crystallization (DC) is developed using the concept of population balance, crystallization/dissolution kin­etics, and dispersion models. The simulated CEF profiles agree well with the experimental CEF profiles of ethylene/1-octene copolymers at various operating conditions.

  2. PEGylated Metalloporphyrin Nanoparticles as a Promising Catalyst for the Heterogeneous Oxidation of Cyclohexene in Water

    Metalloporphyrins are extensively utilized as biomimetic cytochrome P450 models for catalytic oxidation. However, most metalloporphyrins are hydrophobic. PEGylated-metalloporphyrin nano­particles are prepared via a combination of controlled radical polymerization, reactive ester-amine reaction, and in situ self-assembly and “click” cross-linking. The resulting PEGylated-metalloporphyrin nanoparticles in water exhibit a higher catalytic activity than the dissolved metallo­porphyrin in organic solvent.

    Front Cover: A specimen of a triple shape-memory polymer subsequently recovers two memorized shapes. The sequence of shape changes occurring at both ends is determined by the corresponding switching temperatures, which are tunable. The spherical inset represents the anisotropic wide-angle X-ray scattering (WAXS) pattern of the temporary shape (left), and an isotropic pattern is presented when the permanent shape is recovered (right). Further details can be found in the article by U. Nöchel, U. N. Kumar, K. Wang, K. Kratz, M. Behl, and A. Lendlein* on page 2446.
