    The novel technique of coaxial wet-spinning is employed for the fabrication of electroactive biofibres of chitosan/graphene oxide in a basic coagulation bath. As-prepared fibres were found to be cytocompatible with good electrical conductivity and mechanical properties. The results imply that the developed fibres hold a great promise in applications such as drug delivery, batteries and tissue scaffolds in nearby future.

  2. Preparation of Fine-Grained and High-Strength Mg–8Li–3Al–1Zn Alloy by Accumulative Roll Bonding

    Fine-grained and high-strength Mg–8Li–3Al–1Zn alloy is obtained using accumulative roll bonding (ARB) technique. The ARB refines the grains and causes the phase distribution to be scattered. With the increase of ARB passes, the σ0.2,σb, and hardness values are enhanced, whereas the elongation value first decreases, then slightly increases with the increase of ARB passes.

  3. In Situ Electrochemical Analysis during Deformation of a Zr-Based Bulk Metallic Glass: A Sensitive Tool Revealing Early Shear Banding

    Daniel Grell, Petre Flaviu Gostin, Jürgen Eckert, Annett Gebert and Eberhard Kerscher

    Article first published online: 14 JUL 2015 | DOI: 10.1002/adem.201500273

    Two new methods are developed enabling the detection of early shear banding in Zr52.5Cu17.9Al10Ni14.6Ti5 alloy (Vit105) before it can be inferred from macroscopic strain measurements. Shear steps created at the sample surface can be detected by drops in OCP as well as by narrow peaks in current density under potentiostatic polarization.

  4. Al–RE Intermetallic Phase Stability and Effects on Corrosion Behavior in Cold-Chamber HPDC AE44 Alloy

    Yufeng Jiao, Jinghuai Zhang, Lili He, Milin Zhang, Fengchun Jiang, Wei Wang, Liming Han, Longjiang Xu and Ruizhi Wu

    Article first published online: 14 JUL 2015 | DOI: 10.1002/adem.201500226

    Mg–4Al–4RE (wt%, AE44) alloy is prepared by cold-chamber high-pressure die casting (HPDC). The Al–RE phases are investigated by qualitative and quantitative analyses. The microstructure of Al11RE3 would be changed when heated at 400 °C. While after heat treatment at 400 °C for 1000 h and 5000 h, the corrosion resistance performance degrades due to the changes of morphology and distribution of Al–RE phases.

  5. Recent Advances in Processing and Application of Nanostructured Titanium for Dental Implants

    Alexander V. Polyakov, Ludĕk Dluhoš, Grigory S. Dyakonov, Georgy I. Raab and Ruslan Z. Valiev

    Article first published online: 14 JUL 2015 | DOI: 10.1002/adem.201500212

    This paper introduces the results of use of a new ECAP-Conform and drawing processing route for fabrication of nanostructured titanium in the shape of long-length rods for automatic machining of dental implants. Superior properties of nanotitanium rods made it possible to improve the design of implants by considerably reducing their diameter. As evidence, the paper demonstrates the results of successful clinical trials of such implants conducted in cooperation with the Czech company Timplant.
