An innovative gas atomization reaction synthesis technique was employed as a viable method to dramatically lower the processing cost for precursor oxide dispersion forming ferritic stainless steel powders (i.e., Fe-Cr-(Hf,Ti)-Y). During this rapid solidification process the atomized powders were enveloped by a nano-me…
by the steady growth of interest paid to this problem in many areas of chemistry, physics, and materials science (Pomogailo et al.
This paper presents a study of the inverse magnetocaloric effect (MCE) corresponding to martensitic transition using various experimental approaches for Ni 46 Cu 4 Mn 38 Sn 12 and Ni 50 CoMn 34 In 15 Heusler alloy. Through heat capacity measurements, it is found that the "giant inverse MCE" upon martensitic transition…
Nanocrystelline La1-xSrxFeO3(0≤x≤1) was prepared by sol gel citrate method. The structural characterization of the compound was carried out by XRD and SEM. X-Ray diffraction showed that single phase LaFeO3was formed with an orthorhombic structure. DC measurements of the prepared material were investigated from 300K-40…
The aggregation of 85 porphyrin derivatives and a report on a kinetic and thermodynamic study of such aggregation behavior on varying the derivatives of porphyrin was carried out using molecular dynamics simulation and Docking. Distance diagrams of simulated compounds were obtained and decrease of curves is a clear ev…
Solid electrolytes based on chalcogenide glasses have been one of the most promising candidates for the next generation non-volatile memories. Here we propose a new application of chalcogenide solid electrolytes for low cost, high performance microelectronic radiation sensor that reacts to γ-radiation to produce an ea…
The various Crystalline and non-crystalline nickel oxide (NiO) thin films were obtained by spray pyrolysis technique (SPT) using nickel acetate tetrahydrate solutions onto glass substrates at different temperatures from 225 to 350 °C. Structure of the as-deposited NiO thin films have been examined by X-ray diffraction…
Abstract Spectral properties and radiation damage in W, Mg and Ca doped Bi 4 Ge 3 O 12 (W:BGO, Mg:BGO, Ca:BGO) crystals before and after thermal treatment and gamma‐ray (γ‐) or ultraviolet (UV) radiation were studied. The absorption and the photoluminescence (PL) spectra of doped BGO crystals in visible region were me…
Safety design requirements for JSFR were summarized taking the development targets of the FaCT project and design feature of JSFR into account. The related safety principle and requirements for Monju, CRBRP, PRISM, SPX, LWRs, IAEA standards, goals of GIF, basic principle of INPRO etc. were also taken into account so t…
It is shown by Mössbauer spectroscopy of the 119Sb(119m Sn) isotope that impurity antimony atoms in PbS, PbSe, and PbTe lattices are distributed between cation and anion sublattices. In n-type samples, the greatest part of antimony is located in the anion sublattice; in hole ones, in the cation sublattice. The tin ato…
The low-temperature specific heat of layered tetragonal bismuth oxyhalide crystals, prepared by the method of chemical gas transport reactions, is measured. The specific heat is found to have Debye behavior at temperatures below 4 K. The Debye temperatures θD of BiOCl (205 K), BiOBr (168 K), and BiOI (146 K) single cr…
Surface plasmons induced at metal surfaces generate remarkable enhancements of localized electric fields as a result of interactions with incident light fields. This is called localized surface plasmon resonance (LSPR). In this study, we report a simple technique for transferring LSPR-active gold and Au core –Ag shell…
Density functional theory calculations are performed to study the structural, electronic and magnetic properties of hexagonal NiAs type and cubic zinc blende type MnSb structure and interface of zinc blende MnSb with GaSb(001). We used generalized gradiant approximation to calculate the exchange-correlation term in bu…
Indium zinc oxide (IZO) films were deposited on glass substrates using the rf-magnetron sputtering method and a powder target made up of nanoparticles with a size less than 100 nm. In this study, the optical, structural, and electrical properties of the IZO films deposited using a nanopowder target compared with those…
We report a bias temperature instability (BTI) study of graphene Field-Effect Transistor (G-FET) for the first time. New BTI characteristics are observed for G-FETs fabricated using a graphene transfer-free process. Temperature significantly affects BTI of G-FETs by changing the direction of shift of IDS. A plausible…
Molecular dynamics simulations were carried out to investigate the effect of pH on structure and stability of collagen-like peptide. All simulations were performed using the consistent valence force field (CVFF) molecular mechanical force field and isothermal-isobaric ensemble (NPT). The initial geometries of the coll…

The marine small diatoms Nitzschia amabilis, Nitzschia elegantula and Chaetoceros muelleri var. subsalsum are reported for the first time from Chilean coastal waters. A short diagnosis is included for each taxon, and photomicrographs provide information about the main morphological characteristics.
We describe a technique, called polarization difference maps (PDMs), that fully reveals ferroelectric switching of regions within individual grains. Using PDMs, domains that have undergone 90° and 180° switching were mapped for a 100 nm thick polycrystalline lead zirconate titanate (PZT) thin film. Almost half of the…
Dynamics of primary radiation damage, nuclear transmutations, and radioactivity accumulation (activation) and decrease (cooling) during long-term (up to 50 years) irradiation in the neutron spectra of the fast breeder BN-600 and fusion DEMO-RF reactors are calculated using the ACDAM computational system for EK-181 (Fe…
