    Abstract

    The development of solid‐state batteries (SSBs) that do not use hazardous materials as electrolytes and are not flammable is progressing rapidly, however the production of sulfide‐based SSBs requires strict low‐dew‐point control due to their high reactivity with atmospheric moisture and the concern of generating hydrogen sulfide, and several issues remain in terms of the cost and recyclability. Thus, low‐cost facile materials and low‐CO2‐emission processes are necessary. With regard to oxide‐type SSBs, which are attracting attention for their safety, there are issues with manufacturing suitability, as high‐temperature sintering of oxide solid electrolyte particles is required. A new quasi‐solid‐state (QSS) electrolyte with 3D‐ionic conduction and adhesive interfaces by combining amorphous Li2B4O7 and water (3D‐Slime Interface Solid Electrolyte: 3D‐SLISE) is synthesized without stringent dew point control and sintering. Electrode and electrolyte slurries containing 3D‐SLISE are applied to current‐collecting foils in air, naturally dried, and used to construct battery laminates. 3D‐SLISE‐QSSBs (LiCoO2 cathode/3D‐SLISE with 7 wt.% bound‐water/Li4Ti5O12 or TiNb2O7 anodes) maintain several hundred cycles of charge/discharge as a 2.35 V lithium‐ion battery. The 3D‐SLISE‐QSSB technology can promote the use of safe and low‐cost batteries, eliminate the need for a dry room during manufacturing, and enable direct recycling of active materials.

    Abstract

    BaTiO3 powders with various crystallite sizes, which were prepared through microemulsion‐mediated synthesis, were thoroughly studied by Raman spectroscopy. Clear evidence for the presence of the tetragonal phase was found for ultrafine powders with an average crystallite size above 30 nm. The lifetime of phonons that are specifically assigned to the tetragonal phase decreased with decreasing crystallite size below a critical size of 100 nm. In particles as fine as 100 nm, the short mean free path of phonons, mainly due to internal pressure, causes decoupling of the coupled A1 (TO) phonons and a diffuse phase transition behaviour (TC = 115 °C). Coupled A1(TO) phonons, which give a spectral dip at around 180 cm−1 and a lesser extent of diffuseness, were revealed for powders consisting of particles as large as 0.17 µm (TC = 123 °C). Further coarsening upon annealing induced the formation of aggregates, resulting in the shift of phase transition points to higher temperatures for the rhombohedral to orthorhombic and the orthorhombic to tetragonal transitions and to lower temperatures for the tetragonal to cubic transition, respectively. Phase stability in powders is discussed by considering possible factors such as internal pressure in isolated particles and internal stress in aggregates. Copyright © 2007 John Wiley & Sons, Ltd.

    A semiconductive oxide, La2CuO4 (LCO), was investigated as a potential material to compose photocathode for sunlight-driven hydrogen evolution by splitting water. LCO, despite involving partially filled Cu 3d orbitals, behaves as a semiconductor and absorbs visible light on the bandgap formed by significant Coulomb repulsion between the electronic orbitals. An epitaxial LCO film was grown on a SrRuO3/SrTiO3 (SRO/STO) single-crystal substrate by pulsed laser deposition to obtain a photocathodic specimen for water photo-splitting. An LCO photocathode dressed with a Pt cocatalyst for hydrogen evolution (Pt/LCO/SRO/STO) exhibited a cathodic photocurrent with a density of 0.4 mA cm−2 at 0 VRHE under simulated AM1.5 G sunlight. This photocathode responded to incident light up to 800 nm, which is one of the longest wavelengths so far reported for an oxide photoelectrode. Together with a counter-electrode for oxygen evolution, the Pt/LCO/SRO/STO photocathode generated hydrogen with the expected H2 : O2 = 2 : 1 stoichiometric ratio with a Faradaic efficiency of approximately 80%.

    In addition to the structural control of individual carbon nanotubes (CNTs), the morphological control of their assemblies is crucial to realize miniaturized CNT devices. Microgradients in the thickness of catalyst are used to enrich the variety of available self-organized morphologies of CNTs. Microtrenches were fabricated in gate/spacer/cathode trilayers using a conventional self-aligned top-down process and catalyst exhibiting a microgradient in its thickness was formed on the cathode by sputter deposition through gate slits. CNTs, including single-walled CNTs, of up to 1 µm in length were grown within 5–15 s by chemical vapor deposition. The tendency of thin CNTs to aggregate caused interactions between CNTs with different growth rates, yielding various morphologies dependent on the thickness of the catalyst. The field emission properties of several types of CNT assemblies were evaluated. The ability to produce CNTs with tailored morphologies by engineering the spatial distribution of catalysts will enhance their performance in devices.

    Establishing fabrication methods of carbon nanotubes (CNTs) is essential to realize many applications expected for CNTs. Catalytic growth of CNTs on substrates by chemical vapor deposition (CVD) is promising for direct fabrication of CNT devices, and catalyst nanoparticles play a crucial role in such growth. We have developed a simple method called “combinatorial masked deposition (CMD)”, in which catalyst particles of a given series of sizes and compositions are formed on a single substrate by annealing gradient catalyst layers formed by sputtering through a mask. CMD enables preparation of hundreds of catalysts on a wafer, growth of single-walled CNTs (SWCNTs), and evaluation of SWCNT diameter distributions by automated Raman mapping in a single day. CMD helps determinations of the CVD and catalyst windows realizing millimeter-tall SWCNT forest growth in 10 min, and of growth curves for a series of catalysts in a single measurement when combined with real-time monitoring. A catalyst library prepared using CMD yields various CNTs, ranging from individuals, networks, spikes, and to forests of both SWCNTs and multi-walled CNTs, and thus can be used to efficiently evaluate self-organized CNT field emitters, for example. The CMD method is simple yet effective for research of CNT growth methods.

    Abstract

    BaTiO3 dense ceramics with different grain sizes from 5.6 µm down to 35 nm were thoroughly studied by Raman spectroscopy. The temperature characteristics of optical phonons were compared with those obtained for powders. The micrograined ceramic revealed the well‐known spectrum profiles and transitions, typical for bulk BaTiO3. On the other hand, the Raman spectra obtained for a nanograined ceramic with an average grain size of 35 nm revealed a tetragonally distorted pure BaTiO3 phase showing a diffused phase transition behaviour with respect to temperature. Abnormality of phonon damping characteristics for the nanograined ceramic was demonstrated through comparison with powders with various crystallite sizes and the micrograined ceramic. The Curie temperature of the nanograined ceramic was estimated to be 105 °C from the temperature characteristic of a sharp peak at 307 cm−1, which is one of the most specific tetragonal features for bulk BaTiO3. In the present study, local stabilization of the tetragonal phase in ultra‐fine grains was experimentally demonstrated from comparison between the Raman spectroscopic results for powders and ceramics prepared through microemulsion‐mediated synthesis. Rather long phonon mean free paths can exist even in such ultra‐fine grains, but the phonon characteristics originating from various grains are diffused mainly because of the effect of internal stress.

    Monodisperse and nanocrystalline BaTiO3 powders of different stoichiometries were synthesized through the hydrolytic decomposition of mixed metal alkoxide solutions with water‐in‐oil microemulsions as reaction media. The method allows a tailor‐made preparation of powder particles as small as 10 nm in average. Characterization with respect to purity, morphology, and behavior upon annealing was conducted in order to determine appropriate processing conditions for the preparation of pure, dense nanocrystalline ceramics. As a result, ceramics with a mean grain size as small as 35 nm were achieved. Raman spectroscopy revealed for the first time local tetragonality in pure nanocrystalline bulk BaTiO3‐ceramics with such a fine microstructure.

    Abstract

    The present study gives an overview on the potential, possibilities and perspectives that the synthesis of functional materials, such as BaTiO3, with microemulsions as the reaction medium offers. Well defined nanocrystalline particles in the form of powders for further ceramic processing, as well as stable colloidal dispersions for the preparation of coatings may be obtained. The paper describes the formation, phase behaviour and stabilization of microemulsions and related water/oil/surfactant systems that may be used as a nanoreactor during particle formation. The reaction principles of microemulsion mediated synthesis are outlined and some examples of structural aspects, revealing size effects in these systems are implemented using advanced characterization techniques, such as Raman spectroscopy. Finally, the preparation of mesoscopic layers, covering the thickness gap between thin film and thick film technology, is demonstrated.

CNT was produced at 400 °C by the control of the collision energy of carbonic cations to a substrate through a dc bias voltage. The CNTs produced in this work were of a cup-stacked type and had catalyst particles on the top. The CNT emitters formed by our method were integrated into triode-type microcathodes and showed field-emission properties suitable for display applications.

    Abstract

    The conformational equilibria of chloroacetone and bromoacetone in various solvents were investigated using temperature and pressure-tuning Raman spectroscopy. Three conformational equilibria of gauche←→trans, gauche←→trans′ (trans conformer whose halogen atom forms hydrogen bonds with water), and trans←→trans′ were observed in water. Thermodynamic quantities between the conformers of both haloacetones in various solvents were evaluated from the temperature and pressure dependence of the Raman intensities of the C–X (X: Cl and Br) stretching modes. The effects of the substitution of halogen atoms were observed in the enthalpy and volume differences between the conformers in water. From the present results together with the previous results for fluoroacetone, a good correlation between the conformational thermodynamics for haloacetones in water and the polarizabilities of the halogen atoms was shown.

    最有力技術である硫化物系電解質の最大の弱点は大気下における不安定性であり、水分と反応して硫化水素を発生するために安全面に関して懸念されている。酸化物は大気下で合成され、安定性は抜群であるためにこの問題を解決する唯一の方法であるが、しかしながらそのイオン伝導度は硫化物系電解質と比べて低い。さらに硫化物系固体電解質は材料自身の柔らかさより加工性もよい。酸化物材料に足りない加工性およびイオン伝導度に関して、新材料である非晶質リチウム化合物を用いて硫化物に近いイオン伝導並びに凌駕する加工性を付与し、焼結フリーというプロセスコスト面にも優しい固体酸化物電解質を開発する。

    Control of self-organized morphologies of carbon nanotubes (CNTs) was aimed to apply them for electron emitters in field emission (FE) type light emitting elements. In order to form CNT emitters with moderate spacing and number density desirable for an efficient electron source, FE properties ranging from self-organized CNT emitters to macroscopic device properties were systematically studied. Through the multi-scaled evaluation ; control of CNT growth and optimization of device structures, the preparation condition to fulfill their FE properties was highly improved. It is expected that the findings obtained are applied for the processes tolerable for a variety of conventional substrates.
