The changes of amount, distribution and stability of reversed austenite and their effects on the cryogenic toughness of 9Ni steel treated by two-phase region heat treatment were studied with XRD and EBSD. It is found that the cryogenic toughness of the 9Ni steel treated by two-phase region heat treatment is more excel…
In precipitation hardenable materials, it is desirable to determine the precipitate dissolution temperature for homogenizing the microstructure by controlling the size and distribution of the precipitates. In this research, differential thermal analysis, dilatometry technique, heat treatments followed by microstructur…
We have performed a systematic study on the correlation between magnetic anisotropy energy (MAE) and crystal structures, such as lattice parameters, stacking fault densities, lattice strain, and so on, for epitaxially grown Co, Co-Pt, and Co-Pd alloy thin films, and have found that the MAE strongly depends on the axia…
We report on a study of the magnetic domain coupling in epitaxial wedge-shaped Fe layers deposited onto CoO/Ag(001). By using photoelectron emission microscopy (PEEM) in combination with x-ray magnetic circular and linear dichroism (XMCD, XMLD), we imaged the ferromagnetic and antiferromagnetic domains present in the…
Abstract In this article, epoxy foams comprised of diglycidyl ether of bisphenol‐A (DGEBA) based epoxy resin E31 and E51, polyamide resin, and water were prepared by microwave irradiation method. The structure and properties of epoxy foams were analyzed by FTIR, TGA, SEM, and DMA methods. The density and compressive p…
A U(VI) mononuclear coordination complex [UO2(a4-ptz)2·(H2O)3] (1) and a Zn(II) 1-D coordination polymer [Zn(a4-ptz)2·(H2O)2]·2H2O (2) have been synthesized with 5-[N-acetato(4-pyridyl)]tetrazolate (a4-ptz) as ligand. Complex 1 has a slightly distorted pentagonal bipyramid around each U center. Complex 2 is octahedral…
Pervoskite lanthanum ferrite and related compounds have attracted considerably due to their wide applications in fuel cells, catalysts, sensors, and environmental monitoring systems. In this work, lanthanum ferrite and substituted compounds have been prepared by combustion synthesis process using lanthanum nitrate, fe…

Vibrationally resolved differential cross sections (DCSs) for electron impact from the $X\phantom{\rule{0.2em}{0ex}}^{1}\ensuremath{\Sigma}_{g}^{+}({v}^{\ensuremath{''}}=0)$ ground-state level in ${\mathrm{N}}_{2}$ are presented for excitation of the $C\phantom{\rule{0.2em}{0ex}}^{3}\ensuremath{\Pi}_{u}({v}^{\ensurema…
We study the role of the superconducting proximity effect on the electron-phonon energy exchange in diffusive normal metals (N) attached to superconductors (S). The proximity effect modifies the spectral response of the normal metal, in particular the local density of states. This leads to a weakening of the electron-…
Deuteron nuclear magnetic resonance (NMR) and dielectric spectroscopy are utilized to investigate the dynamics of the water molecules in the semiclathrate (tetra-n-butyl ammonium bromide) 26 H(2)O. Stimulated-echo spectroscopy reveals a nonexponential correlation function predominantly due to rotational motion with ju…
Anisotropic thermal transport in cross-linked polybutadienes deformed in simple elongation is investigated experimentally. Using a novel optical technique based on forced Rayleigh scattering, two components of the thermal diffusivity tensor are measured as a function of stretch ratio. The thermal diffusivity is found…
Abstract Clothing and apparel are high value‐added products, and body measurement standards are crucial industrial standards in apparel manufacturing. These standards enable manufacturers to predict sales of different sizes and set production quantities accordingly, resulting in accurate material control and productio…
Abstract Despite their importance, rigorous process models are rarely available for reaction and especially multi‐phase reaction systems. The high complexity of these systems, which is due to the superposed effects of mass transfer and intrinsic reaction, is the major barrier for the development of process models. A m…
Resonant inelastic soft x-ray inelastic-scattering (RIXS) spectra of single-crystal iron ilmenite ${\text{FeTiO}}_{3}$ were measured at the $\text{Ti}\text{ }2p$ resonance, and additional peaks at $\ensuremath{-}2.5$ and $\ensuremath{-}4.5\text{ }\text{eV}$ in energy loss were observed. In order to investigate the ori…
OBJECTIVES: Synthetic and biological materials are increasingly used to provide temporary or permanent scaffolds for bone regeneration. This study evaluated the effect of material chemistry and microporosity on bone ingrowth and osseointegration of zirconia (ZrO(2)) and hydroxyapatite (HA) scaffolds in the human maxil…
Mesoporous zirconia, hydrothermally synthesized from surfactant templating, was directly impregnated with aluminum sulfate to give the acidic Al-promoted sulfated mesoporous zirconia (AS/MP-ZrO 2 ). A series of AS/MP-ZrO 2 catalysts were characterized by Brunauer−Emmett−Teller and X-ray diffraction for their texture p…
While magnetic hysteresis usually considers magnetic domains, the switching of the core of magnetic vortices has recently become an active topic. We considered Bloch domain walls, which are known to display at the surface of thin films flux-closure features called Néel caps. We demonstrated the controlled switching of…
A study was conducted to provide an access route to diene-functionalized polymers through atom transfer radical polymerization (ATRP) and their utilization in the reversible addition-fragmentation chain transfer (RAFT)-hetero-Diels-Alder (HDA) protocol, which opened the possibilities of controlled radical polymerizati…
In the minimultimedia market, functional diversity, high performance, and design are given top priority. Lightweight mobile phones of unique design especially attract customer interest and are usually considered to be highly competitive items in the marketplace. Therefore, mobile phones need wider and thinner liquid c…
