A straightforward method of PDA-MBG modification on an artificial ligament is used to promote its biocompatibility and bioactivity in vitro and in vivo. And the modified PET artificial ligament is shown to be an efficient process for enhancing the bioactivity of the PET. The surface modification on PET-based artificial ligament may be a novel applied for ligament reconstruction.
- Effects of Ag Addition on Hot Deformation Behavior of Cu–Ni–Si Alloys

Hot deformation behavior of Cu–Ni–Si and Cu–Ni–Si–Ag alloys is investigated. Dynamic recrystallization (DRX) mechanism is a feature of high temperature flow stress–strain curves of the alloy. Ag addition can refine the grains and accelerate dynamic recrystallization. Processing maps are developed and analyzed based on the dynamic material model (DMM). Ag addition can optimize the alloy processing workability.
- Mechanism of Dynamic Formation of Ultrafine Ferrite Grains during High Temperature Processing in Steel
Lijia Zhao, Nokeun Park, Yanzhong Tian, Akinobu Shibata and Nobuhiro Tsuji

Grain refinement mechanism of ferrite dynamically transformed (DT) from austenite is clarified. The study shows that the role of dynamic recrystallization (DRX) has been previously underestimated in grain refinement of ferrite and it is suggested that new thermomechanical processes should be developed by enhancing the DRX (of DT ferrite), which has a strong strain rate dependency.
- Development of Graphene Nano-Platelet Ink for High Voltage Flexible Dye Sensitized Solar Cells with Cobalt Complex Electrolytes
Jennifer A. Baker, Carys Worsley, Harrison K. H. Lee, Ronald N. Clark, Wing C. Tsoi, Geraint Williams, David A. Worsley, David T. Gethin and Trystan M. Watson

This work develops a GNP ink of high surface area which can be printed using roll to roll technologies to produce a semi-transparent catalyst. Post deposition the ink needs only a 110 °C drying step enabling the use of plastic substrates. Flexible dye sensitized solar cells suitable for indoor applications are produced with efficiencies of over 6.0%.
- Advanced Raman Spectroscopy Using Nanofocusing of Light
Thomas Nuytten, Janusz Bogdanowicz, Thomas Hantschel, Andreas Schulze, Paola Favia, Hugo Bender, Ingrid De Wolf and Wilfried Vandervorst
Version of Record online: 13 JAN 2017 | DOI: 10.1002/adem.201600612
The dramatic enhancement of Raman scattering intensities from periodic arrays of narrow semiconductor fins is reported. For a variety of materials, nanofocusing of the incident light translates Raman spectroscopy into the nanoscale world. This, in turn, enables optical stress and composition metrology on deep-subwavelength semiconductor architectures.
