Metallic nanoparticles have been actively investigated in recent years by different optical and laser methods with the purpose of their applications in optoelectronics and photonics, chemistry, laser nanobiomedicine, optical diagnostics, and other fields. A major role among metallic nanoparticles is played by nanopart…
We have probed the interfacial magnetism between La0.7Sr0.3MnO3 (LSMO) and La0.7Sr0.3CoO3 (LSCO) layers in a [LSMO(10 u.c.)/LSCO(10 u.c.)]X6 superlattice (SL) using X-ray magnetic circular dichroism and photoemission electron microscopy. Strong magnetic coupling exists between the LSMO and LSCO layers such that the ma…
The magnetoelectric properties of the TbMn(1-x)Sc(x)O3 series have been studied at low temperatures by means of heat capacity, magnetic measurements and impedance spectroscopy. TbMnO3 exhibits as expected three transitions upon lowering the temperature corresponding to the magnetic ordering of the two sublattices (Mn…
We have investigated the magnetic and transport properties of a noncentrosymmetric compound PrRhSi3 by dc magnetic susceptibility χ(T), isothermal magnetization M(H), thermoremanent magnetization M(t), specific heat Cp(T), electrical resistivity ρ(T,H) and muon spin relaxation (μSR) measurements. At low fields χ(T) sh…
We perform first principles calculations of the magnetocrystalline anisotropy energy (MAE) of the L1_{0}-like Fe_{x}Pt_{1-x} samples studied experimentally by Barmak and co-workers in [J. Appl. Phys. 98 (2005) 033904]. The variation of composition and long-range chemical order in the samples was studied in terms of th…
Poly(lactic acid)/organo-montmorillonite (PLA/OMMT) nanocomposite films were prepared through solution intercalation using dichloromethane as solvent. X-ray diffraction indicated that organo-montmorillonite (OMMT) was well intercalated and the interlayer spacing d increased by 0.94–1.47 nm. Transmission Electron Micro…
Ba 8 CuTa 6 O 24−δ ceramics possess exceptionally high microwave dielectric loss among the eight‐layer twinned hexagonal perovskite Ba 8 MTa 6 O 24 (M = Zn, Co, Ni, Mg, Cu) analogs. Impedance spectroscopy measurement demonstrates that the eight‐layer Ba 8 CuTa 6 O 24−δ ceramics show the electrical heterogeneous micros…
Unsealed radioactive sources used in Nuclear Medicine Centers, to diagnose and treat patients, pose significant risks of internal exposure to the occupational staff. This work intends to evaluate the potential risks of internal contamination of occupational staff in Nuclear Medicine facilities. 49 urine samples of 19…
We present a linear nano-polarizer composed of asymmetric nanoaperture and bowtie nanoantenna, which provides a new way to freely control the polarization azimuth of the translated optical field in the near-field. It can not only generate large localized field enhancement and outstanding spatial confinement, but also…
Abstract A quartz tube with inner wall contaminated by Escherichia coli bacteria is treated using an atmospheric pressure nitrogen afterglow flowing at 20 SLM. The biocidal efficacy is measured locally at both the input and at the output of a 57 cm tube, giving a reduction of survivors of around 5 and 4 log for a 40 m…
We report galvanic deposition of Mo films onto 6061 Al alloy from aqueous solutions containing 1 mM HNO 3 and 10 mM MoCl 5 . Deposition for 40 min. yields an 9 μm thick Mo film, which also contains 18 atom% Al. The corrosion resistance of the Mo film is studied by voltammetry and electrochemical impedance spectroscopy…
The distillation behavior of mixed alcohols was studied by use of the Advanced Distillation Curve (ADC) methodology. Crude mixed alcohols (oxygenates) were generated from syngas over a potassium-promoted cobalt–molybdenum-sulfide catalyst and assayed for major and minor products. Distillation (boiling) curves were gen…
Submicron SiCp/Cu composite was fabricated by means of powder metallurgy route followed by hot extrusion, and then its morphology and mechanical properties were investigated. The results showed that densification of the composite was achieved by this fabricating process when the content of submicron SiC particle was b…
ABSTRACT With the increased use of carbon fiber reinforced composites (CFRC), the demand for the integration of insulated conductive wire/yarns in CFRC is increasing for additional function integrations such as sensoric, actoric, signal transfer, heating, etc. Between thermoset and thermoplastic matrix composites, the…
A natural nontronite clay sample from the Amazon region (Tocantins State, Serra da Messa Group, Brazil) was utilized for synthesis of a new biomaterial produced by a hybridization process of inorganic and organic materials. The new biomaterial was composed of an Amazon nontronite and fungal mass obtained from the Aspe…
ABSTRACT To synthesize the novel molecular‐ and pH‐stimulus‐responsive hydrogel, we prepared poly(ethylene glycol)‐based hydrogel containing ionic groups. We evaluated the fundamental swelling/shrinking properties of the hydrogels synthesized by various conditions. Decreasing the molecular weight of a crosslinker prov…
This paper gives an overview of a robust dielectric barrier discharge reactor-catalyst construction used in a bypass of a marine diesel-engine exhaust gas system. Electrode arrangement, housing, and electrode positioning systems are discussed allowing for high temperature and reasonable vibration operation. Preliminar…
The past few decades have witnessed the development of intricate strategies and management in pharmaceutical research to combat various diseases and provide physical comfort to the living beings. Efforts are on to design efficient drug delivery systems, achieve desirable therapeutic objectives and to minimise drug-ind…
Using ab initio alloy theory, we determine the elastic parameters of ferromagnetic and paramagnetic Fe(1-c)Cr(c) (0 ≤ c ≤ 1) alloys in the body centered cubic crystallographic phase. Comparison with the experimental data demonstrates that the employed theoretical approach accurately describes the observed composition…
Dilute glutathione solutions containing NaCl need to be purified and concentrated. Nanofiltration (NF) would be a good solution, provided that it could completely reject glutathione while permeating NaCl entirely. Commercially available NF membranes are incapable of meeting both of these targets. Therefore, in this st…
