The effects of biaxial strain on the electrical and magnetic properties of an antiferromagnetic Heusler compound Fe2VSi were systematically investigated. A series of epitaxial Fe2VSi thin films on MgAl2O4 and MgO substrates were fabricated with different tensile strains by varying the substrate-lattice mismatch and th…
Graphene has been attracting a strong interest as a transparent electrode as well as a THz nanoelectronic device owing to its unique properties. To date, large-area graphene growth has been realized by chemical vapor deposition (CVD) with a catalyst metal. To avoid the transfer of segregated graphene, we have examined…
An outstanding experimental issue in the physics of composites concerns the reliable extraction of the intrinsic dielectric characteristics from effective permittivity measurements of heterostructures. Though recent analytical and numerical models have made progress in tackling this question, their applicability is ty…
Antibody modified magnetic polymeric microspheres have potential biomedical application. In this paper, anti-CD40 antibody modified magnetic poly(epsilon-caprolactone)-poly(ethylene glycol)-poly(epsilon-caprolactone) (PCL-PEG-PCL, PCEC) microspheres were prepared. First, PCL-PEG-PCL triblock copolymer was synthesized…
Abstract A liquid-crystalline phenylterthiophene derivative which exhibits a nematic phase at room temperature has been prepared. The hole mobility in the nematic phase at room temperature reaches 4 × 10−4 cm2 V−1 s−1. This value is two orders of magnitude larger than those of amorphous organic semiconductors and comp…
Alkyl-Grignard addition to meso-tetraphenylporpholactone generates monoalkyl- and gem-bis-alkyloxazolochlorins. Together with compounds made by further synthetic manipulations of these derivatives, a series of chlorin-type chromophores with modulated optical properties is generated. Furthermore, their OsO(4)-mediated…
Bioconjugation, a novel technique is usually exploited to improve the biopharmaceutical aspects of a bioactive as well as afford its spatial and temporal distribution. The strategy enlightens newer vistas for delivery of drugs, peptides, enzymes, and oligonucleotides. Site specific delivery may be obtained by tailorin…
The solubility of aluminum hydroxide in seawater of 35‰ salinity at pH = 7.4−8.2 and 25°C was determined experimentally for three samples synthesized in different ways. The solubilities of two phases subjected to ageing and precipitated (a) from a boiling solution of aluminum sulfate and (b) immediately from seawater…
Abstract We present a three‐dimensional thermodynamically‐consistent phenomenological model for the magneto‐mechanical behavior of magnetic shape memory materials featuring a cubic‐totetragonal martensitic transformation. Existence of energetic solutions for both the constitutive relation problem and the three‐dimensi…
As a group of wonder materials, gold and silver at the nanoscale demonstrate many intriguing properties that cannot be seen from their bulk counterparts. However, consistent insight into the mechanism behind the fascinations and their interdependence given by one integrated model is highly desirable. Based on Goldschm…
A green, low-cost, and reproducible bael (Aegle marmelos) leaves–negotiated synthesis of gold nanoparticles is reported. Synthesis was performed at room temperature. X-ray, selected-area electron diffraction (SAED) and transmission electron microscopy analyses were performed to ascertain the formation of Au nanopartic…
Raman spectra of epitaxal BiFeO3 thin films, grown on (111) SrTiO3 substrates, have been studied in temperature range 300–800 K. All four prominent A1-symmetry (81, 138, 170, and 214 cm−1) Raman modes show evolution with the temperature near the Néel temperature (TN), which is interpreted due to spin lattice coupling…

Bulk SmCo5/α-Fe nanocomposite magnets have been prepared using a Joule-heating compaction technique. Nearly fully dense bulk magnets are obtained by compacting the milled powders under a pressure of 2 GPa at temperatures above 400 °C. Structural analysis shows that the grain size of both the SmCo5 and the α-Fe phases…
We present the results of experimental studies of heat and mass transfer processes in a metal hydride reactor under absorption and release of pure hydrogen. The hydrogen absorption/release reaction is shown to proceed in three stages: (I) heating/cooling of the absorbing material bed up to the reaction temperature; (I…
In this paper, we present a model for temperature dependent hysteretic nonlinearities with nonlocal memories. This model can be applied to describe hysteretic material behavior. Common applications are ferromagnetic or magnetostrictive materials. Our model consists mainly of a Preisach operator with a continuous Preis…
Promotion of angiogenesis in tissue engineering is of vital significance to the survival of transplants, which leads the way of tissue regeneration. In this study, we screened six short peptides with potentially angiogenic activities to functionalize self-assembling peptide nanofiber scaffolds RADA16-I (Ac-(RADA)4-CON…
Fast reactor metal fuels containing minor actinides (MAs) Np, Am, and Cm and rare earths (REs) Y, Nd, Ce, and Gd are being developed by the Central Research Institute of Electric Power Industry (CRIEPI) in collaboration with the Institute for Transuranium Elements (ITU) in the METAPHIX project. The basic properties of…
This work is focused on the evolution of structure, texture and magnetic properties in SmCo5 powders during high energy ball milling (HEBM) in heptane with and without oleic acid (OA). Single-crystal micron SmCo5 flakes were formed in the early stage of HEBM (0–0.5 h). However, HEBM of 1–2 h without OA led to the form…
Ti-doped ZnO nanowires (NWs) were fabricated by thermal evaporation and metal vapor vacuum arc (MEVVA) ion implantation process. The effect of Ti doping on the structure, morphology, and electrical/optical properties of the as-grown NWs was investigated. The fraction of Ti doping was estimated to be 1 at. % to 2 at. %…
