Single crystal SmMnO${}_{3}$ has been grown by the floating-zone method. We have measured the magnetization and specific heat in magnetic fields oriented along three principal crystal axes of precisely oriented single crystals. Below ${T}_{N}$ of the Mn${}^{3+}$-ion array, the magnetic moments of the Sm${}^{3+}$ ions…
The influences of a local interband transition on optical absorptions of plasmonic nanoparticles are investigated. It is found that the optical absorption associated with a local interband transition is remarkably enhanced because of the presence of a localized surface plasmon resonance. On the basis of the quasistati…
Multicritical behavior of interacting fermions in graphene's honeycomb lattice is presented. In particular, we considered the spin triplet insulating orders, where the spin rotational symmetry of the order parameter is explicitly broken. By casting the problem in terms of Gross-Neveu-Yukawa theory, we show that such s…
The electronic properties of the layered transition metal dichalcogenide ZrS${}_{x}$Se${}_{2\ensuremath{-}x}$ semiconductors for $x$ $=$ 0 and 2 as well as for the ternary compound with $x$ $=$ 1 have been calculated by density functional theory for six different exchange-correlation energy approximations by the wien2…
We report Raman scattering measurements on iron-pnictide superconductor Ba(Fe${}_{1\ensuremath{-}x}$Co${}_{x}$)${}_{2}$As${}_{2}$ single crystals with varying cobalt $x$ content. The electronic Raman continuum shows a strong spectral weight redistribution upon entering the magnetic phase induced by the opening of the…
A methodology for fabricating hierarchical nanostructures by surface-confined synthesis of silver nanoparticles on electrospun polyimide nanofibers is reported. Through surface-confined imide cleavage at the dianhydride domain via immersion in an aqueous KOH solution, potassium polyamate coatings of accurately defined…
We report large-yield production of graphene flakes on glass by anodic bonding. Under optimum conditions, we counted several tens of flakes with lateral size around 20-30 μm and a few tens of flakes with larger size. About 60-70% of the flakes have a negligible D peak. We show that it is possible to easily transfer th…
1,10-Phenanthroline (phen) and monoprotonated methylamine molecules were used as a novel cotemplate to direct the formation of a new inorganic-organic hybrid selenidostannate, (CH(3)NH(3))(4)(Sn(2)Se(6))·6phen (1); while the utilization of three types of transition-metal (TM) phen complex cations with the TM/phen rati…
Development of a rapid, sensitive, and multiplex pathogen DNA sensor enables early diagnosis and, subsequently, the proper treatment of infectious diseases, increasing the possibility to save the lives of infected patients. Here, the development of an ultrasensitive and multiplex pathogen DNA detection method that com…
Nano-objects and thin films displaying molecular spin-crossover phenomena have recently attracted much attention. However, the investigation of spin crossover at reduced sizes is still a big challenge. Here we demonstrate that surface plasmon polariton waves propagating along the interface between a metal and a dielec…
Abstract A one‐pot and readily practical approach is described for the preparation of superstrong, ultrathin, free‐standing single‐walled carbon nanotube (SWNT) films. The SWNT films, with controlled thicknesses of tens to hundreds of nanometers, are prepared from commonly commercialized SWNTs via a wet process. The S…
This paper aims to investigate quantitatively the characteristics of the storage and slip of ammonia in a full-size vanadium-based selective catalytic reduction (SCR) catalyst under typical steady and transient conditions on a diesel engine test bench. The effect of space velocity (SV) and exhaust temperature on the a…
Probing the pressure-induced structural changes and the extent of disorder in aluminosilicate glasses and melts at high pressure remains a challenge in modern physical and chemical sciences. With an aim of establishing a systematic relationship between pressure, composition, and glass structures, we report 27 Al and 1…
This concise review focuses on dendrimers functionalized by different linkers required for covalent and ionic attachments of drugs to the dendrimer's surface and highlights the importance of the chemical nature of linkers for controlled release of free drugs. The stability of linkers under physiological conditions and…
Cell within a cell: Interfacial membrane formation by cation exchange of polyoxometalates produces modular inorganic chemical cells with tunable morphology, properties, and composition (see picture). These inorganic chemical cells (iCHELLs), which show redox activity, chirality, as well as selective permeability towar…
Wood cellulose was converted to individual nanofibers of approximately 4 nm width and 380-570 nm average length by TEMPO-mediated oxidation. The TEMPO-oxidized cellulose nanofibers (TOCNs) were orally administered with glucose and glyceryl trioleate to mice and postprandial responses of blood glucose, insulin, glucose…
We have successfully designed an A:B:C collagen peptide heterotrimer using an automated computational approach. The algorithm maximizes the energy gap between the target and competing misfolded states while enforcing a minimum target stability. Circular dichroism (CD) measurements confirm that all three peptides are r…
Several unsymmetrically 2,5-disubstituted BODIPY dyes were obtained from 2-substituted derivatives (iodo, ethynylaryl) using a regioselective Knoevenagel condensation reaction with dimethylaminobenzaldehyde. The unsaturated, unsymmetrical 2-ethynyl-5-styryl-BODIPY undergoes a regioselective [2 + 2] cycloaddition react…
Enhance the reactivity: By combined experimental and theoretical studies of vanadium–yttrium oxide cluster cations and other related reaction systems, local charge effects on methane activation by oxygen-centered radicals (O−.), as well as nonradical oxygen species (O2−), have been demonstrated and can serve as a fund…
Domain states in PbZr((0.42))Ti((0.58))O(3) single-crystal ferroelectric nanodots, formed on cooling through the Curie temperature, were imaged by transmission electron microscopy. In the majority of cases, 90° stripe domains were found to form into four distinct "bundles" or quadrants. Detailed analysis of the dipole…
