Spatial diffusion reflection (DR) measurements of gold nanorods (GNR) were recently suggested as a simple and highly sensitive non-invasive and non-ionizing method for real-time cancer detection. In this paper we demonstrate that wavelength dependent DR measurements enable the spectral red-shift observation of highly…
Type-I clathrate phase Ba(8)Ni(x)□(y)Si(46-x-y) (□ = vacancy) was obtained from the elements at 1000 °C with the homogeneity range 2.4 ≤ x ≤ 3.8 and 0 ≤ y ≤ 0.9. In addition, samples with low Ni content (x = 1.4 and 1.6; y = 0) and small Ba deficiency were prepared from the melt by steel-quenching. Compositions were e…
The interpretation of the effect of plastic deformation on the calculated excess loss component (anomalous-loss) supports the concept of loss separation. Magnetic losses and Barkhausen noise of nonoriented electrical steel sheets were measured on Epstein strips taken from a single coil of 0.8%Si nonoriented electrical…
We show that a plasmonic metamaterial can act as a far-field to near-field transformer that focuses a free-space beam of light into a subwavelength energy hot spot at a prescribed location with a spot size only a small fraction of the wavelength. The hot spot position on the metamaterial can be prescribed and moved at…
The accurate measurement and calculation of transformer no-load losses is of high importance to transformer users and manufacturers alike. There are various ways of calculating no-load losses of transformers based on empirical formulas and experimentally obtained coefficients but these tend to mostly apply to known an…
Arrays of silver nanorods (AgNRs) formed by oblique-angle deposition (OAD) are strongly anisotropic, with either metallic or dielectric characteristics depending on the polarization of incident light, and may be used to enhance Raman scattering and surface plasmon polaritons. This work investigates the polarization-de…
While outstanding functional properties of thin NiTi wires are nowadays well recognized and beneficially utilized in medical NiTi devices, development of 2D/3D wire structures made out of these NiTi wires remains challenging and mostly unexplored. The research is driven by the idea of creating novel 2D/3D smart struct…
The crystalline/crystalline poly( l -lactic acid)/poly(1,4-butylene adipate) (PLLA/PBA) blend system exhibits upper critical solution temperature (UCST) behavior below the melting temperature of PLLA. When the PLLA/PBA (50/50) blend is cooled to crystallize below UCST, phase-separated domains appear prior to crystalli…
We design a dual-view liquid crystal display (DVLCD) which display two different images in the left and right viewing directions simultaneously. The main-pixel of the DVLCD comprises the right sub-pixels (RSPs) and the left sub-pixels (LSPs). The LCs in the RSPs and the LSPs have the opposite rotation directions, whic…
Nylon-3 polymers have a polyamide backbone reminiscent of that found in proteins (β- vs α-amino acid residues, respectively), which makes these materials interesting for biological applications. Because of the versatility of the ring-opening polymerization process and the variety of β-lactam starting materials availab…
Biosystem-surface interactions play an important role in various biological events and determine the ultimate functionality of implanted devices. Endothelialization or mimicking of endothelium on the surface of cardiovascular materials is a promising way to solve the problems of material-induced thrombosis and resteno…
The preparation of well-defined luminescent organoboron quinolate block copolymers via sequential RAFT polymerization is reported. Boron-containing block copolymers with PS, P(St- alt -MAh), and PNIPAM as the second block were successfully synthesized. The photophysical properties of the block copolymers were studied…
We develop a numerical technique for simulating metamaterial electromagnetic response based on an adaptation of the discrete dipole approximation (DDA). Our approach reduces each constituent metamaterial element within the composite to a point dipole with electric and magnetic polarizabilities, rather than assuming a…
The origin of the Ti 3d defect state seen in the band gap for reduced rutile TiO(2)(110) surfaces has been excitingly debated. The probable candidates are bridging O vacancies (V(O)) and Ti interstitials (Ti-int) condensed near the surfaces. The aim of this study is to give insights into the source of the gap state vi…
The Fermi surface of the ferromagnetic shape-memory alloy Ni 2 MnGa has been determined experimentally with two-dimensional angular correlation of electron–positron annihilation radiation. Our results are supported by first principles electronic structure calculations. The measured electron occupancy within the Brillo…
Dynamics of water, especially in the temperature range of the "no man's land", remain a mystery. We present detailed study of dynamics in aqueous LiCl solution that is often considered as a model for bulk water. We employ broadband dielectric and light scattering spectroscopy in a broad frequency and temperature range…
High-frequency electromagnetic wave (EM-wave) absorbing characteristics of metal alloy/spinel ferrite/polymer composite materials with various metal alloy particle contents were evaluated from measurements of complex permeability$\mu=\mu^{\prime}-{\rm j}\mu^{\prime\prime}$by the coaxial reflection method in the freque…
Nowadays it is difficult to imagine a life without thermoplastic elastomers. The uses of\nthermoplastic elastomers have increased because of its specific properties, such as low\ncost, light weight, high strength, non-biodegradability, durability, non-corrosive\nnature, process ability and high energy effectiveness. H…
Electrical steel sheets, which are used in real rotating machinery, are magnetized under alternating and rotating magnetic flux conditions. In addition, the magnetic properties of the electrical steel sheets are strongly affected by stress. Therefore, it is important to understand the magnetic properties under differe…
We describe the synthesis of a bisporphyrin tweezer receptor 1·H(4) and its metalation with Zn(II) and Rh(III) cations. We report the thermodynamic characterization of the supramolecular chirality induction process that takes place when the metalated bisporphyrin receptors coordinate to enantiopure 1,2-diaminocyclohex…
