The work reported herein investigates the effect of milling time on the spark plasma sintering kinetics and microstructural evolution of 14LMT alloy, a nanostructured ferritic steel, containing lanthanum instead of yttrium. The predominance of grain boundary diffusion during sintering is noted. Microstructure is characterized by SEM/EBSD and TEM, and mechanical property by Vickers microhardness technique.

The footprint of organic electronic technologies is important when united in complex circuitry. We describe the area requirements for roll-to-roll processed electrochromics, solar cells, and printed organic power transistors in joint operation of a large area window shading application and find that organic power transistors and OPVs can drive electrochromics while taking up very little area.

The room temperature shear strength of the joint brazed with the amorphous filler is always much higher than that with the crystalline filler, and the maximum joint shear strength is 202 MPa at a brazing temperature of 1 000 °C. The differences in performance of the joints are related to the microstructure characteristics of the brazing seams.
- Fabrication of Coaxial Wet-Spun Graphene–Chitosan Biofibers

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.
- 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.
