A novel method involving the fabrication of Mo-W mixed oxide (MoWO) is proposed to modify the modest reaction kinetics and poor cycling stability of MoO material. By a simple coelectrodeposition method, a series of MoWO oxides is deposited on a TiO nanotube array substrate. Because of the differences between Mo and W in nature, there is significant distortion existing in the mixed oxides, leading to their decreased crystallite size and enlarged lattice space, which facilitates ion diffusion in the solid. As results, the mixed oxides show much better balance between specific capacitance and cycling stability than the bare MoO or WO sample, which suffers from either poor cycling stability or low electrochemical activity. Impressively, the optimal Mo-W mixed oxide exhibits a high specific capacitance of 517.4 F g at 1 A g, and, moreover, it retains 89.3% of the capacitance even at a high current density of 10 A g, demonstrating ultrahigh rate capability. These findings reveal the potential of the Mo-W mixed oxide for constructing advanced ultrahigh power supercapacitors.

Purpose -The purpose of this paper is to analyze the potential of strategic environmental assessment (SEA) to mainstream consideration of climate change adaptation (CCA) in Bangladesh, particularly for the coastal zone, to improve disaster risk reduction (DRR) strategies in this region. Continuing climate risks require adaptation at all levels of society. The densely populated and resource-rich coastal zone of Bangladesh is at risk to the impacts of climate change.Design/methodology/approach -This research is based on secondary sources (gray and published literature) of information on climate change impacts on the coastal zone of Bangladesh. The sources include research reports, online publications, governmental reports, scientific journals, international reports, books, journal articles and other academic resources on SEA, climate change adaptation and mitigation, and DRR. In addition to examining SEA in Bangladesh, this paper investigates SEA cases in different countries to obtain insights from the successful application of SEA for CCA.Findings -The paper draws on several cases from different countries demonstrating that SEA has a significant potential to coordinate CCA objectives. The findings reveal that the appropriate use of SEA can enable DRR through CCA.Originality/value -This study argues that SEA has a potential role in supporting CCA.
