    <p>Ti<sub>1−2</sub><i><sub>x</sub></i>(FeNb)<i><sub>x</sub></i>O<sub>2</sub> solid solutions were prepared as visible-light-active photocatalysts using a conventional solid-state reaction method. Ti<sub>1−2</sub><i><sub>x</sub></i>(FeNb)<i><sub>x</sub></i>O<sub>2</sub> solid solutions were obtained below <i>x</i> = 0.25 without any secondary phase. They exhibited light absorption in the visible region. The strong absorption corresponding to the bandgap shifted to the lower energies with increasing <i>x</i>. Because the valence band maxima of the samples remained unchanged, the conduction band minima shifted to lower energies. The photocatalytic activity was evaluated based on the degradation of methylene blue under UV–visible light irradiation. The photocatalytic activity of Ti<sub>1−2</sub><i><sub>x</sub></i>(FeNb)<i><sub>x</sub></i>O<sub>2</sub> solid solutions tends to improve with increasing <i>x</i>. Clear visible light photocatalytic activity corresponding to the band gap was also observed. Thus, these materials are promising candidates for environmental applications.</p>

    The processing of porous architectures based on Layered Double Hydroxides (LDH) is reviewed. Especially, a focus was put on porosity in nm and μm ranges that can be prepared via various post-treatments and templating techniques for the enhancement of the original properties. A challenge toward the desired porosity is control of structural ordering as well as crystal growth of LDH. The present review paper is mainly dedicated to summarizing the synthetic approaches to access the porous LDH that have found a wide range of applications such as adsorption/environment purification, catalysis, energy storage & production and bio-applications.

    <p>Perovskite-structured transition metal oxides, <i>AM</i>O<sub>3</sub>, demonstrate catalytic activities for oxygen evolution reaction (OER), which can be enhanced by chemical substitutions for both <i>A</i>- and <i>M</i>-sites. Considerable efforts are needed to realize the optimum composition with high OER activity because of the huge composition space for doped perovskites of <i>A</i><sub>1−</sub><i><sub>x</sub>A</i>′<i><sub>x</sub>M</i><sub>1−</sub><i><sub>y</sub>M</i>′<i><sub>y</sub></i>O<sub>3</sub>, where <i>A</i> and <i>M</i> ions can be respectively replaced by <i>A</i>′ and <i>M</i>′ ions at arbitrary ratios. Combinatorial synthesis methods were extensively utilized to examine the properties of overall compositions of transition metal oxides. However, perovskite oxides requiring high-temperature treatments were not eligible for the above methods because of the low heat resistance of the conductive substrate, such as indium tin oxide glass and carbon. In this study, we propose an efficient method using the high-temperature synthesis of polycrystalline thin films of perovskite oxides on quartz glasses and Pt films to systematically investigate the OER catalytic activities of perovskite oxides of La<sub>1−</sub><i><sub>x</sub></i>Sr<i><sub>x</sub></i>Fe<sub>1−</sub><i><sub>y</sub></i>Co<i><sub>y</sub></i>O<sub>3</sub> with 100 distinct chemical compositions in 0 ≤ <i>x</i> ≤ 0.9 and 0 ≤ <i>y</i> ≤ 0.9. X-ray diffractometry confirmed that all the samples loaded on the quartz glass crystallized in perovskite structures, whereas the electrochemical study unveiled a continuous landscape depending on both <i>x</i> and <i>y</i> for La<sub>1−</sub><i><sub>x</sub></i>Sr<i><sub>x</sub></i>Fe<sub>1−</sub><i><sub>y</sub></i>Co<i><sub>y</sub></i>O<sub>3</sub>. The present method proposes the high-throughput screening for highly active OER perovskite oxide catalysts.</p>

    Catalytic hydrogenation of aromatic nitro compounds containing multiple functional groups into corresponding amino compounds with high conversion rates, selectivity, and stability under mild conditions is a great challenge. Herein, we demonstrated low-cost CoAl LDH materials showing efficacy in the catalytic reduction of nitroarenes due to its highly active nature and own unique physical and chemical properties. The as-synthesized CoAl LDH catalysts exhibited a high conversion rate and selectivity for the hydrogenation of 7 different aromatic nitro compounds with different competing groups into the structure of the amino compounds using sodium borohydride under mild conditions (room temperature and 1 atm). The reaction was completed in a short time in between 5 and 150 min. The catalyst also showed excellent stability and could be reused over 8 times without considerably losing its activity.

    <p>Xonotlite, with a chemical formula of Ca<sub>6</sub>(Si<sub>6</sub>O<sub>17</sub>)(OH)<sub>2</sub>, has been widely used as a thermal insulation material due to its high porosity and chemical/physical stabilities. As a potential recycle use of Xonotlite, CO<sub>2</sub> fixation is promising when considering its high alkali content and macroporous structure. In this study, Xonotlite was chemically activated to form nanocomposites of silica and calcium salt by optimizing an acid treatment. It was found that Xonotlite treated with acetic acid at 1.0 mol/L keeps the original macroporous structure of Xonotlite, and simultaneously segregates calcium salt on the surface of the residual silica. The nanocomposite of silica and calcium salt exhibits the capability of CO<sub>2</sub> fixation and high cycle stability thanks to the unique structural feature of the composite.</p>

    <p>Stoichiometric hydroxyapatite (HAp) nanoparticles were prepared by the solution-precipitation method at 37 °C. During the 72-h maturation period, the Ca/P molar ratio first rapidly increased to >1.6, and then reached 1.67 relatively slowly. The crystallite sizes of the stoichiometric HAp nanoparticles were estimated to be 11.0(3) and 25.7(3) nm from 300 and 002 diffractions, respectively. The crystallite size in the [001] direction continued to increase after the 72-h maturation period at a constant Ca/P molar ratio of 1.67. The obtained stoichiometric HAp nanoparticles also exhibited higher thermal stability than commercially available HAP-100 and prevented grain growth during sintering. This material is suitable for use in various sintering methods.</p>

    <p>The reaction of stoichiometric hydroxyapatite (HAp) with different crystallinity in Mg<sup>2+</sup> aqueous solution was investigated using X-ray absorption near edge structure (XANES). Crystallinity is one of important factors for the properties of HAp. Therefore, this study aimed to clarify the effect of crystallinity on the behavior of HAp in aqueous solutions. Stoichiometric HAp samples with different crystallinities were prepared using an aqueous solution precipitation method and subsequent calcination. The Mg-<i>K</i> XANES spectra of the HAp pellets after immersing in Mg(NO<sub>3</sub>)<sub>2</sub> aqueous solution were classified into two groups: those of Mg-doped HAp and Mg(OH)<sub>2</sub>. This difference is caused by the solubility of the HAp pellets in water, owing to their crystallinity. This result provides insights into the reaction mechanism of HAp in the human body and facilitates selection of suitable biomaterials.</p>

    <p>Zirconia nanoparticles were synthesized by using the supercritical hydrothermal method from zirconium basic carbonate, which is insoluble in water at ambient temperature. The diameters of these nanoparticles were 10–20 nm. They contained both tetragonal and monoclinic phases. A long treatment in supercritical water induced the phase transition from the tetragonal phase to the monoclinic phase with the desorption of carbonate ions. These results indicated that the carbonate ions absorbed on the surface works as a stabilizer of the unstable tetragonal phase. The process developed here allows us to bypass wastewater treatment along with the product refining because byproducts are only water and carbon dioxide.</p>

    Chiral inorganic materials have attracted increasing attention in the fields such as catalysis, electronics, photonics, and sensing. A new class of functional materials with chirality is extensively explored. Herein, we demonstrate the synthesis of nanometric nickel layered hydroxide salt (Ni-LHS) modified with chiral amino acids, (D- or L-) phenylalanine (PHE). An alkalization reaction in a starting mixture of nickel-phenylalanine aqua complexes was induced by using propylene oxide, leading to intercalate and adsorb phenylalanine on the surface and into the interlayers of Ni-LHS in an in-situ manner. The chiral molecules also act as surface modifier to inhibit the extensive crystal growth and aggregation, to form Ni-LHS with a diameter of 2–3 nm in a state of stablly-suspended in a solvent. It was also found that Ni-LHS exhibit induced circular dichroism (ICD) in the spectral range of d-d transitions of Ni(II) metal centres. The layered nanomaterials with chiroptical response demonstrated here is a promising option as an advanced adsorbent for detection of molecules. [Figure not available: see fulltext.]

    Multi-scale structural assessment of biological soft tissue is challenging but essential to gain insight into structure-function relationships of tissue/organ. Using the human placenta as an example, this study brings together sophisticated sample preparation protocols, advanced imaging and robust, validated machine-learning segmentation techniques to provide the first massively multi-scale and multi-domain information that enables detailed morphological and functional analyses of both maternal and fetal placental domains. Finally, we quantify the scale-dependent error in morphological metrics of heterogeneous placental tissue, estimating the minimal tissue scale needed in extracting meaningful biological data. The developed protocol is beneficial for high-throughput investigation of structure-function relationships in both normal and diseased placentas, allowing us to optimize therapeutic approaches for pathological pregnancies. In addition, the methodology presented is applicable in the characterization of tissue architecture and physiological behaviours of other complex organs with similarity to the placenta, where an exchange barrier possesses circulating vascular and avascular fluid spaces.

    Li-Al layered double hydroxide (LDH) and LDH-derived mixed metal oxide (MMO) are promising solid base catalysts due to their instinct and strong surface basicity. Herein, nano Li-Al LDH was synthesized via the crystal growth from metal hydroxide nanoseeds with low crystallinities. The present Li-Al LDH possesses high specific surface area (326 m2 g−1), highly crystalline, and high purity. The present nano LDH undergoes a transformation to Li-Al MMO with a high specific surface area (349 m2 g−1) of abundant strong basic sites. Indeed, the present Li-Al MMO exhibits an enhanced catalytic activity for a transesterification reaction between methanol and soybean oil compared to one prepared through a co-precipitation method, thanks to the larger amount of active sites.

  • Reactivity of silanol group on siloxane oligomers for designing molecular structure and surface wettability Reviewed

    Molecular structures of siloxane materials should be highly controlled for achieving advanced functionalities. However, it is still difficult to precisely control the structure of siloxane materials by the sol–gel processing. In the present study, we focused on the silanol groups in the intermediate oligomers and resultant siloxane materials as a key structural unit for controlling the molecular structure. Thermal stability and chemical reactivity of silanol groups were found to be highly dependent on the steric effects of the surrounding side chains and siloxane skeletons. The present work suggests that controlling the steric effects around silanol groups in the intermediate oligomers allows modulating the crosslink density of siloxane skeletons. The selective molecular modification tunes the structure and chemical properties of the resultant siloxane materials. [Figure not available: see fulltext.]

    Colloidal suspension of NiGa2O4 nanoparticles was synthesized by gel-sol method. Starting from an aqueous solution of Ni(NO3)2·6H2O, Ga(NO3)3·nH2O and a β-diketone ligand (acetylacetone), a precursory hydrogel was obtained through an epoxide-mediated alkalization. Then, a mild thermal treatment at 80 °C induces the deflocculation of the hydrogel, resulting in the formation of NiGa2O4 nanoparticles which is stably suspended in a solvent. The formation mechanism of the colloidal suspension was closely studied, revealing that chelation of acetylacetone to Ni cation with the formation of NiGa2O4 nanoparticles plays a key role to impart dispersion stability.

    © 2020 American Chemical Society. Enormous efforts have been devoted to the development of crystalline aerogels toward heterogeneous catalysis, energy storage, ion/molecular absorption, and luminescence. However, properties of aerogels are not fully exploited due to their low content of functional moieties embedded in their solid networks, low crystallinity, and limited chemical compositions. Herein, we develop a one-pot approach based on crystallization from amorphous metal hydroxides modified with a β-diketone ligand, toward crystalline transition-metal hydroxide aerogels. Synthesis of monolithic and crystalline aerogels of layered double hydroxide (LDH) was performed in a Ni-Al system starting from aqueous ethanol solutions of NiCl2·6H2O and AlCl3·6H2O with acetylacetone (acac) as an organic ligand. Propylene oxide (PO) as an alkalization reagent was added into precursory solutions to yield monolithic wet gels. The successive pH increase induces the formation of a three-dimensional (3-D) solid framework composed of amorphous Al(OH)3. Then, amphoteric Al(OH)3 undergoes crystallization into Ni-Al LDH via an acetylacetone-driven dissolution-crystallization of metal hydroxides without destroying the preformed 3-D solid framework. The process allows us to obtain crystalline aerogel monoliths with high porosity and high transparency after supercritical CO2 drying of wet gels. The present scheme can be expected to synthesize functionalized aerogel composed of crystalline transition-metal oxide/hydroxide nanobuilding blocks (NBBs).

    © 2020 The Royal Society of Chemistry. Controlling the direction of molecular-scale pores enables the accommodation of guest molecular-scale species with alignment in the desired direction, allowing for the development of high-performance mechanical, thermal, electronic, photonic and biomedical organic devices (host-guest approach). Regularly ordered 1D nanochannels of metal-organic frameworks (MOFs) have been demonstrated as superior hosts for aligning functional molecules and polymers. However, controlling the orientation of MOF films with 1D nanochannels at commercially relevant scales remains a significant challenge. Here, we report the fabrication of macroscopically oriented films of Cu-based pillar-layered MOFs having regularly ordered 1D nanochannels. The direction of 1D nanochannels is controllable by optimizing the crystal growth process; 1D nanochannels align either perpendicular or parallel to substrates, offering molecular-scale pore arrays for a macroscopic alignment of functional guest molecules in the desired direction. Due to the fundamental interest and widespread technological importance of controlling the alignment of functional molecules and polymers in a particular direction, orientation-controllable MOF films will open up the possibility of realising the potential of MOFs in advanced technologies.

    Copyright © 2020 American Chemical Society. To develop electrochromic thin films for smart windows and low-power displays, homogeneous thin films were produced by spin coating colloidal NiAl layered double hydroxide (LDH) nanocluster solutions on a fluorine-doped tin oxide (FTO) glass substrate. The nano-LDH dispersion was synthesized via a facile one-step epoxide mediated process at room temperature. In situ relative transmittance measurements at 400 nm, recorded during potential scans in cyclic voltammetry or differential pulse chronoamperometry, showed the electrochromic behavior of the homogeneous thin films. The impact of various parameters on the electrochromic properties of the films was detailed, such as the thickness of the film, the nature of the electrolyte, and the presence of electroactive anions. The electrochromic properties, namely, the change in transmittance (T) and the bleaching reversibility, were greatly improved using alkaline metal hydroxide as the electrolyte and in the presence of Fe(CN)64-. The performances that we reached from the deposition of nanoclusters can be advantageously compared to the literature with T = 70% and fast and good reversibility. Upon calcination, the NiAl-LDH film converted into mixed oxides (NiO and NiAl2O4). The higher the calcination temperature, the lower was the T value. The presence of porosity within the thin films, through the introduction of sacrificial polymeric beads and then decomposition at 400 °C, was investigated, highlighting an enhancement of the T value attributed to better accessibility to the nickel redox sites.

    © The Royal Society of Chemistry. A novel approach for thermo-responsive wettability has been accomplished by surface roughness change induced by thermal expansion of paraffin coated on titanate nanostructures. The surface exhibits thermo-responsive and reversible wettability change in a hydrophobic regime; the surface shows superhydrophobicity with contact angles of ∼157° below 50 °C and ∼118° above 50 °C due to a decrease of surface roughness caused by thermally-expanded paraffin at higher temperatures. Reversible wettability change of ∼40° of a contact angle allows for fast and multi-directional droplet transport. The present approach affords a versatile selection of materials and wide variety of contact angles, promoting both scientific advancement and technology innovation in the field of smart surfaces.

    © 2020 American Chemical Society. Layered double hydroxides (LDHs) are a class of materials that act as adsorbents of anionic molecules because of their positively charged layered structure. One appealing application is optical sensors where the LDH acts as a host material to adsorb and concentrate the probes for low-threshold detection. Herein, we demonstrate a prototype of an optical sensing system combining the nanosized LDHs (nano-LDHs) and the plasmonic substrate. The nano-LDHs are obtained as a colloidal dispersion in an aqueous solution with a high concentration via epoxide-driven alkalization. The nano-LDHs adsorb fluorescein molecules, a model analyte, faster than the micrometer-sized coarse LDHs prepared by a standard method, thanks to their nanosized geometry and highly homogeneous dispersion in water. After concentrating fluorescein molecules by adsorbing them onto the surface, the nano-LDHs are deposited on the plasmonic substrate consisting of a periodic array of aluminum nanocylinders for the fluorescence detection of fluorescein. The substrate enhances the fluorescence from the nano-LDH film with fluorescein up to 18 times by resonating both the excitation and emission light with plasmonic modes. Given the fast adsorption of the analyte by nano-LDHs and the benefit of fluorescence enhancement by the plasmonic substrate to reduce the detection threshold, we believe that this strategy of concentrating analytes by nano-LDHs and detecting them by fluorescence enhancement on the plasmonic substrate is inspiring in building sensing systems.

    Imparting an enhanced CO2 reduction selectivity to ZnGa2O4 photocatalysts has been demonstrated by controlled crystallization from interdispersed nanoparticles of zinc and gallium hydroxides. The hydroxide precursor in which Zn(ii) and Ga(iii) are homogeneously interdispersed was prepared through an epoxide-driven sol-gel reaction. ZnGa2O4 obtained by a heat-treatment exhibits a higher surface basicity and an enhanced affinity for CO2 molecules than previously-reported standard ZnGa2O4. The enhanced affinity for CO2 molecules of the resultant ZnGa2O4 leads to highly-selective CO evolution in CO2 photo-reduction with H2O reductants. The present scheme is promising to achieve desirable surface chemistry on metal oxide photocatalysts.

    © 2019 by the authors. Licensee MDPI, Basel, Switzerland. A design of atomic and oligomer level structure in organic-inorganic hybrid materials is highly important for various applications. Nonaqueous acid-base reaction allows us to prepare silicophosphates with controlled inorganic networks (-(O-P-O-Si)n) at atomic level because phosphorous and silicon-based precursors can react directly, resulting in an alternating copolymer network. Organic functionalization in those materials has been realized so far by using organic-modified phosphorous acid and/or organo-chlorosilane as precursors. In the present study, silicophosphate oligomers exhibiting inorganic-organic hybrid chains of (-(O-P-O-Si-R-Si)n) (R: bridging organic functional groups), are prepared from phosphoric acid and organo-bridged bis(chlorosilane). The 1, 2-bis(chlorodimethylsilyl)ethane ((C2H4)(Me2SiCl)2) and 1, 4-bis(chlorodimethylsilyl)benzene ((C6H4)(Me2SiCl)2) were used as organo-bridged bis(chlorosilane). Different types of silicophosphate oligomers with different network structures and terminal groups (P-OH and/or Si-Cl) were prepared by changing the reaction temperature and molar ratio of precursors. The formation of low molecular weight oligomers of ring and cage morphologies (ring tetramer, cage pentamer, and ring hexamer) is suggested in the product prepared from phosphoric acid and (C6H4)(Me2SiCl)2 molecule at 150 °C. Those silicophosphate hybrid oligomers are expected to be used as building blocks of hybrid materials with well-defined network structures for desired functionalities.

    The precise alignment of multiple layers of metal–organic framework (MOF) thin films, or MOF-on-MOF films, over macroscopic length scales is presented. The MOF-on-MOF films are fabricated by epitaxially matching the interface. The first MOF layer (Cu2(BPDC)2, BPDC=biphenyl-4,4′-dicarboxylate) is grown on an oriented Cu(OH)2 film by a “one-pot” approach. Aligned second (Cu2(BDC)2, BDC=benzene 1,4-dicarboxylate, or Cu2(BPYDC)2, BPYDC=2,2′-bipyridine-5,5′-dicarboxylate) MOF layers can be deposited using liquid-phase epitaxy. The co-orientation of the MOF films is confirmed by X-ray diffraction. Importantly, our strategy allows for the synthesis of aligned MOF films, for example, Cu2(BPYDC)2, that cannot be grown on a Cu(OH)2 surface. We show that aligned MOF films furnished with Ag nanoparticles show a unique anisotropic plasmon resonance. Our MOF-on-MOF approach expands the chemistry of heteroepitaxially oriented MOF films and provides a new toolbox for multifunctional porous coatings.

    Deformation of the mesostructures in surfactant/silica hybrid films and mesoporous silica films prepared on bulky elastomeric substrates is investigated by compressing the substrates along an in-plane direction of the films. The mesostructure in the surfactant/silica hybrid film consists of organized micelles and a silica matrix. The micelles are removed in the mesoporous silica films to leave mesopores. A grazing-incidence small-angle X-ray scattering investigation reveals that the mesostructures with C2mm symmetry anisotropically change under a compressive strain of 6% in both films; shrinkage of the lattice parameters is along the direction of compression and extension in the normal direction. Deformation is reversible below a strain as high as 6%. Anisotropic deformation of the mesostructures results in an anisotropic change of the refractive indices normal and parallel to the direction of the compression. Compression of the surfactant/silica hybrid film induces a decrease of the refractive index parallel to the surface and an increase normal to the surface on the order of 10-3, while an opposite result is observed for the mesoporous silica film. The present finding gives us fundamental insight into the development of adaptive optical components for sensing, attenuation, switching, modulation, shutters, filters, and others in soft-material-based devices.

    X-ray micro computed tomography(X線μ-CT)は非破壊で物体の3次元画像を得るための技術の一つである。解像度が高い上,薄切標本を観察する蛍光イメージングと異なり,組織全体を3次元でイメージングできる。一方で,X線μ-CTの大きな欠点は,生体組織のイメージングにおいてコントラストが低いことである。本稿では,筆者らの近年の研究成果を中心に,「新規造影剤開発」という材料化学的アプローチにより,上記問題点に挑戦した例を紹介する。(著者抄録)
