    This work describes the development of a self-cleaning coating using a nanoparticle coated super hydrophobic sol–gel. The material is flexible, transparent and robust, and suitable for application to optical windows or solar panels. The coating can be easily applied as a two-part solution by spraying.

  2. The Enhanced Shape Memory Effect and Mechanical Properties in Thermomechanically Processed Semi-Equiatomic NiTi Shape Memory Alloy

    The hot compression tests were carried out in a wide range of temperatures and strain rates. A significant influence on the critical transformation temperatures was realized. This could affect the martensite plates’ features and the fraction of retained austenite phase. In consequence the room temperature mechanical properties and shape memory response of the alloy were influenced. In an optimized specimen, the recovery ratio was increased from ≈30% to ≈80%.

  3. Size Effects in the Mechanical Properties of Bulk Bicontinuous Ta/Cu Nanocomposites Made by Liquid Metal Dealloying

    Extremely strong and ductile Cu/Ta bulk nanocomposites are fabricated by liquid metal dealloying. These materials exhibit a complex two-phase microstructure with a tunable length scale that allows for a significant increase in strength with decreasing feature size. Their yield behavior is consistent with a bulk manifestation of size effects previously associated only with nanofabricated materials.

  4. A Flexible Encapsulation Structure for Ambient-Air Operation of Light-Emitting Electrochemical Cells

    A. Asadpoordarvish, A. Sandström and L. Edman

    Article first published online: 26 JUN 2015 | DOI: 10.1002/adem.201500245

    We report the fabrication and ambient-air performance of flexible light-emitting electrochemical cells (LECs). A flexible LEC sandwiched between multilayer barriers, featuring a water and oxygen barrier property of ≈1 × 10−3 g/m2/day and ≈1 × 10−3 cm3/m2/bar/day respectively, and as attached together with UV-curable epoxy, performs on par with identical glass-encapsulated devices. Such a flexible LEC also remains functional after one year storage under ambient air.

  5. Stimulation by Pearl of Mineralization and Biocompatibility of PLA

    PLA/pearl composited scaffold has been successfully fabricated, which can obviously stimulate hydroxyapatite (HA) deposition compared with pristine PLA as measured by mineralization. MTT assay result demonstrates that pearl is beneficial to improve the biocompatibility of PLA. The cells show a more extended morphology on P20 than pristine PLA according to the SEM. As a result, the PLA/pearl composite material might be a superior candidate for bone repair.
