Electronic-Insulating Coating of CaCO3 on TiO2 Electrode in Dye-Sensitized Solar Cells: Improvement of Electron Lifetime and Efficiency

Abstract: Electronic-insulating coating of CaCO3 on nanocrystalline TiO2 electrode for dye-sensitized solar cells was found to increase both short-circuit photocurrent (Jsc) and open-circuit photovoltage (Voc) remarkably. The significant increase in Jsc is mainly attributed to the remarkably increased dye adsorption resulting from the more basic surface of CaCO3 than TiO2, while the increase in Voc originates from suppression of charge recombination owing to the surface covering of TiO2 with an insulating coating of CaCO3, revealed by intensity-modulated photovoltage spectroscopy. A 15 μm TiO2 (23 nm) nanocrystalline electrode coated with 1 wt % CaCO3, sensitized with N719, produced power conversion efficiency of 10.2%, where N719 is cis-di(thiocyanato)-bis(2,2‘-bipyridyl-4,4‘-dicarboxylate) ruthenium(II), using an antireflective film on the cell surface.

Cybernetic human HRP-4C

Abstract: The development of cybernetic human HRP-4C is presented in this paper. The word “Cybernetic Human” is a coinage for us to explain a humanoid robot with a realistic head and a realistic figure of a human being. HRP-4C stands for Humanoid Robotics Platform-4 (Cybernetic human). Standing 158 [cm] tall and weighting 43 [kg] (including batteries), with the joints and dimensions set to average values for young Japanese females, HRP-4C looks very human-like. This paper introduces the design process, mechanical features, and electrical features with specifications of HRP-4C.

Puffing Up Energetic Metal–Organic Frameworks to Large Carbon Networks with Hierarchical Porosity and Atomically Dispersed Metal Sites

Abstract: Large carbon networks featuring hierarchical pores and atomically dispersed metal sites (ADMSs) are ideal materials for energy storage and conversion due to the spatially continuous conductive networks and highly active ADMSs. However, it is a challenge to synthesize such ADMS-decorated carbon networks. Here, an innovative fusion-foaming methodology is presented in which energetic metal-organic framework (EMOF) nanoparticles are puffed up to submillimeter-scaled ADMS-decorated carbon networks via a one-step pyrolysis. Their extraordinary catalytic performance towards oxygen reduction reaction verifies the practicability of this synthetic approach. Moreover, this approach can be readily applicable to a wide range of unexplored EMOFs, expanding scopes for future materials design.

Bimetallic Metal–Organic Frameworks for Gas Storage and Separation

Abstract: Emerging as a new family of hybrid crystalline materials, bimetallic porous metal–organic frameworks (MOFs) have received great attention in gas storage and separation. We present a critical perspective on the construction of bimetallic MOFs, involving one-step synthesis and postsynthetic modification, and their applications in gas storage and separation. In particular, several examples of bimetallic MOFs have been provided to better understand of why such MOFs are so unique for these applications. We hope that the present perspective will inspire chemists working in this area to rationally design/develop new bimetallic MOFs for advanced applications.
