We summarize recent theoretical and experimental work in the field of magnetic small-angle neutron scattering (SANS) of bulk ferromagnets. The response of the magnetization to spatially inhomogeneous magnetic anisotropy and magnetostatic stray fields is computed using linearized micromagnetic theory, and the ensuing s…
A switchable water-adhesive, super-hydrophobic nanowire surface is developed for the formation of functional stem cell spheroids. The sizes of hADSC spheroids are readily controllable on the surface. Our surface increases cell-cell and cell-matrix interaction, which improves viability and paracrine secretion of the sp…
Insects and plants are two types of organisms that are widely separated on the evolutionary tree; for example, plants are mostly phototrophic organisms whilst insects are heterotrophic organisms. In order to cope with environmental stresses, their surfaces have developed cuticular layers that consist of highly sophist…
The catalytic performance of Pd-based intermetallic compounds supported on silica (Pd m M n /SiO 2: M = Bi, Fe, Ge, In, Sn, Zn) was investigated in oxidative dehydrogenation of 1-butene and n -butane. A remarkable increase in selectivity (and also yield) of dehydrogenation products (1,3-butadiene and/or 1-butene) was…
BACKGROUND: Nanoparticle pharmacokinetics and biological effects are influenced by several factors. We assessed the effects of amorphous SiO2 coating on the pharmacokinetics of zinc oxide nanoparticles (ZnO NPs) following intratracheal (IT) instillation and gavage in rats. METHODS: Uncoated and SiO2-coated ZnO NPs wer…
Non-wetting super-hydrophobic or super-lyophobic surfaces are of great interest in a variety of applications. Natural water repelling surfaces show micro-/nano- combined hierarchical structure which shows extremely low wettability and self-cleaning characteristics. Inspired by such natural wonders, there have been tre…
In this work, tungsten triboride (WB 3 ) was successfully synthesized at high pressure and high temperature. The structure was reconfirmed to be WB 3 ( P 6 3 mmc ), and some part has a tungsten atomic defect according to the measurement results of X-ray diffraction, high-resolution transmission electron microscopy, an…
The particulate nanoporous material MCM-48 (Mobil Crystalline Material No. 48) was synthesized and characterized in order to use it as an adsorbent for the removal of adsorbate, such as aniline and nitro-substituted anilines, including 2-nitroaniline, 3-nitroaniline, and 4-nitroaniline from wastewater. The characteriz…
The inherently large surface area and electrical conductivity of graphene-like electrodes have motivated extensive research for their use in supercapacitors. Although these properties are beneficial for the electric double layer (EDL) capacitance, the full utilization of graphene is curtailed by its intrinsically limi…
Healable, electrically conductive films are essential for the fabrication of reliable electronic devices to reduce their replacement and maintenance costs. Here we report the fabrication of near-infrared (NIR) light-enabled healable, highly electrically conductive films by depositing silver nanowires (AgNWs) on polyca…

A bioderived and ecofriendly hybrid nanocomposite was developed from soy protein and eggshell nanopowder (ESNP). ESNP was synthesized via size reduction of chicken eggshells using ball milling followed by a sonochemical process. Transmission electron microscopy and X-ray diffraction (XRD) studies revealed calcite part…
Switchable organic conductors can be readily obtained by combining organic conducting polymers (CPs), with the unparalleled bistability of spin crossover (SCO) complexes. Here it is reported how CPs with embedded SCO components exhibit synergic multistability. Upon acting on the SCO probes by external stimuli (thermal…
We have investigated the magnetic, dielectric and magnetodielectric (MDE) behavior of a geometrically frustrated spin-chain system, Ca3Co1.4Rh0.6O6, in the single crystalline form for different orientations. The results bring out that the magnetic behavior of this compound is by itself interesting in the sense that th…
We present a framework to carry out highly accurate $\mathrm{GGA}+U$ thermochemistry calculations by deriving effective $U$ values from experimental data. The $U$ values predicted in this approach are applied to metal cations, and depend not only on (i) the chemical identity and the band to which the $U$ correction is…
The high-temperature phase transition between the tetragonal (scheelite) and monoclinic (fergusonite) forms of yttrium tantalite (${\mathrm{YTaO}}_{4}$ ) has been studied using a combination of first-principles calculations and a Landau free-energy expansion. Calculations of the Gibbs free energies show that the monoc…
The investigation of ultrafast electronic and structural dynamics in low-dimensional systems like nanowires and two-dimensional materials requires femtosecond probes providing high spatial resolution and strong interaction with small volume samples. Low-energy electrons exhibit large scattering cross sections and high…
Far-infrared reflection and ellipsometry measurements on multiferroic ${\mathrm{PrFe}}_{3}({\mathrm{BO}}_{3}){}_{4}$ and ${\mathrm{SmFe}}_{3}({\mathrm{BO}}_{3}){}_{4}$ single crystals were used to investigate the interaction between lattice phonons and electronic excitations associated with $4f$ crystal-field transiti…
We report the results of direct measurement of remanent hysteresis loops on nanochains of ${\mathrm{BiFeO}}_{3}$ at room temperature under zero and $\ensuremath{\sim}20$ kOe magnetic field. We noticed a suppression of remanent polarization by nearly $\ensuremath{\sim}40%$ under the magnetic field. The powder neutron d…
We report $^{209}$Bi nuclear magnetic resonance (NMR) spectra of in nanowires and single crystals of Bi$_2$Se$_3$. Crystals were powdered to simulate the random orientation of the nanowires, and the spectra are compared with theoretical expectations derived via an orientational study of a single crystal. The nanowire…
