AB  - The discovery of nanostructured materials led to ground-breaking findings and significant technological advancement in recent years and is therefore attracting continuous attention from both, academia, and industry for a variety of structural and functional applications [1]. To design nanostructured materials with new functionalities, we combine electrochemical and electroless chemical synthesis with structural studies on different length scales including transmission electron microscopy. The possibility to produce nanostructured metals containing nanoscaled twins, both growth twins and deformation twins, is considered as a promising approach for the synthesis of novel high-performance materials in recent years [1]. Unfortunately, the phenomenon of twinning occurs only in certain metals, such as copper and until recently, it seemed impossible to make aluminium with a high density of grown-in twins. In the present work, we demonstrate the use of electrodeposition as synthesis method to make Al layers with a high density of genuine growth twins [2]. This unexpected result demonstrates a versatile and cost-effective nanoengineering technique for the formation of pure Al layers with a high density of twins. The atomic structure of a twin in aluminium is shown in a transmission electron microscopy image (cf. Fig. 1). In high density, these symmetric lattice imperfections can yield a material that shows good electrical properties, high hardness and good deformability. In addition, we show that electrochemical synthesis approaches can be used to create high surface area functionalized foams and ordered nanostructures for potential sensing and energy-related applications [3-6].

AB  - To contribute to the knowledge on the influence of synthesis procedure on the intercalation kinetics of lithium ions into phospho-olivines, LiFePO4/C composite samples (LFPC) were synthesized in two ways, the first one in a sol-gel procedure (SG), and the other in a solid-state reaction (SS). The X-ray diffractograms (XRD) of both samples overlapped with that of pure LiFePO4, taken from the crystallographic database. Scanning electron microscopy pictures indicated the high degree of interparticle sintering, which caused a considerable agglomerate growth. The results of potentiodynamic measurements in aqueous LiNO3 solution revealed that for SS sample, three times higher initial capacity from that of SG one, (amounting to 74 mAh g−1 at 5 mV s−1). However, capacity fade on rising scan rate is much more expressed for SS sample than for SG one. We suggest that a different degree of material utilization due to the incomplete coverage of olivine particles by carbon explains this difference. The technique of separation of diffusion and capacitance currents was applied in a kinetic analysis, but it was shown to be inappropriate. We suggest the inapplicability of classic CV theory to the intercalation system accompanied by phase transition. Instead, a model of ohmic resistance determination of process kinetics was considered. LFPC-SS sample delivers three times larger capacity in LiNO3, amounting to 74 mAh g−1 at 1 mV s−1.
