We report the effect of in situ transforming ZnO supported single Au atoms to 3-dimensional Au clusters (Au3D) on room temperature CO oxidation activity. We discovered that an intermediate, highly distorted 2-dimensional Au layer species is much more active than both the Au3D clusters and the Au single atoms. The geom…
To improve dye retention, there is a concurrent interest in the development and optimization of an alternative and promising method for the dye recovery in aqueous solutions. In this regard, considerable attention was paid to the polyoxometalates (POMs) assisted ultrafi ltration (POMAUF). The aim of the present study i…
The conceptualization and development of a test rig able to reproduce thermal stresses and contact with molten aluminum alloy, typical of high‐pressure die‐casting dies, are described. During the test, a hot‐work tool steel sample is cyclically heated by contact with molten aluminum alloy (AlSi11Cu2(Fe)) and then cool…
Polyaniline (PANI)/copper oxide nano composite (PCN) was synthesized by electrochemical deposition method. The PCN nanocomposite was characterized by using Fourier transform infra-red (FT-IR) spectroscopy, x-ray diffraction (XRD), UV-Visible absorption spectroscopy, field emission scanning electron microscopy (FESEM),…
The reduction of anthropogenic greenhouse gas emissions is crucial to avoid further warming of the planet. We investigated how effluent gases from a biogas powered Euro VI heavy-duty engine impact the performance of a bimetallic (palladium and platinum) oxidation catalyst. Using synthetic gas mixtures, the oxidation o…
This chapter gives a general overview of synthesis and recent development of nickel oxide as a nonstoichiometric compound. We establish the synthesis chemistry of nickel oxide as a nonstoichiometric material, and hence successively introduce definitions and classifications of nonstoichiometric compounds as well as the…
Research on damping structural integrated polymers has become an inevitable trend; they develop orientation in modern engineering materials. In this work, two high modulus epoxy resins (VSE and VDE) with superior damping properties were prepared by condensation reaction and addition reaction with 9,10-dihydro-9-oxa-10…
Adenine-functionalized supramolecular micelles are rapidly endocytosed by cancer cells and enable selective induction of tumor cell death, without harming normal cells.
Electroreflectance (ER) spectra of β-Ga2O3 were measured using Schottky barrier diodes. The ER spectra were well fitted to a third derivative line shape function by assuming three excitonic transitions. The transition energies exhibited moderate blueshifts with an external reverse bias by reflecting the contribution o…
Fundamental understanding regarding oxygen storage capacity involving how and why an active site can buffer a large number of oxygen atoms in redox processes is vital to the design of advanced oxygen storage materials, while it is challenging because of the complexity of heterogeneous catalysis. Herein, we identified…
${\mathrm{Bi}}_{1\ensuremath{-}\mathit{x}}{\mathrm{Sr}}_{\mathit{x}}{\mathrm{FeO}}_{3\ensuremath{-}\ensuremath{\delta}}$ (BSFs) are well known not only as multiferroic materials but also as mixed oxide-ion and electronic conductors. BSFs show remarkable ionic conductivity despite their limited electrochemical activity…
We report simulation studies on the self-assembly of hard-lobed particles (patchy particles where patches appear as lobes around a seed) of different shapes and show that various types of self-assembled morphologies can be achieved by tuning inter-lobe interactions. On self-assembly, the linear building blocks having…
The energy and spin diffusion behaviors in the one-dimensional classical Heisenberg spin chain have been systematically investigated using the equilibrium diffusion method. The spatiotemporal autocorrelation functions for energy and spin are calculated at finite and infinite temperatures. As conserved quantities, the…
Magnetically oriented three-phase composite systems of epoxy resin, aluminum nitride, and nickel have been prepared, the thermal conductivity of composites filled with nickel powder with different particle sizes and content under different applied magnetic fields was studied. The vibrating scanning magnetometer (VSM)…

The massive production of nanostructures with controlled features and high surface area is a challenging and timely task in view of developing effective materials for sensing and catalysis. Herein, functional ZnO nanostructures, named microflowers (MFs) have been prepared by a facile and rapid chemical bath deposition…
The present study is performed on the way and mechanism by which ion size changes curves of differential electrical capacitance ( C d ) vs surface charge strength |σ| and energy storage density E vs applied voltage U of an electrical double layer (EDL) formed inside a cylindrical pore electrode. Several valuable findi…
Hafnium diboride (HfB2) is one of the most promising hard-brittle ceramic materials with unique physical properties. Here, we have synthesized the well-crystallized HfB2 by a high-pressure solid-state reaction and employ in situ high-pressure synchrotron radiation angle-dispersive X-ray diffraction to investigate the…
We use an ab initio approach to design and study a two-dimensional material---a planar array of carbon nanotubes separated by an optimal distance defined by the van der Waals interaction. We show that the energy spectrum for an array of quasimetallic nanotubes is described by a strongly anisotropic hyperbolic dispersi…
Conventional composite cathodes used in solid oxide fuel cells (SOFCs) are fabricated by co-sintering of electrocatalyst and ionic conductor powders at 1100–1250 °C. The relatively high-temperature heat treatments required to ensure bonding among the powders and between the powders and electrolyte results in the forma…
