In this paper, the authors describe a simple and inexpensive method for fabricating a superhydrophobic surface on Ti6Al4V alloy substrate without any chemical modification by means of constructing an appropriate surface roughness. Most interestingly, we found that the as-prepared surface has good mechanical properties…
The shell thickness of a BaTiO 3 ceramic with a core–shell structure has been measured by means of synchrotron X‐ray diffraction (XRD). BaTiO 3 ceramic is known from transmission electron microscope (TEM)/energy dispersive X‐ray spectroscopy (EDS) observations to have an inhomogeneous microstructure with cores of a pu…
We have detected a typical relaxor/glasslike dielectric response in the derived lead-free (1−x)K0.5Na0.5NbO3-(x)SrZrO3 ceramic system. In the compositional range 0.10≤x≤0.33, where solid solubility was observed, the system exhibits a broad dispersive dielectric maximum, a Vogel–Fulcher temperature dependence of the ch…
In spite of conventional treatment modalities which include surgery, chemotherapy, and radiotherapy, the survival rates for patients with malignant gliomas remain disappointing. Successful treatment has been limited by difficulties in delivering therapeutic agents to the central nervous system (CNS). Specifically, dru…
Abstract Room temperature focused electron beam (FEB) induced deposition of contamination‐free transparent materials is a major issue for the FEB production of nano‐optical structures, microchip editing (insulating and passivation layers), and photolithography mask repair. In this work, stoichiometric SiO 2 is success…
Nanofibers are solid-state linear nanomaterials with diameters <100 nm, an aspect ratio >1000 and are characterized by high surface area to volume ratio. Nanofibers, due to their high surface area to volume ratio are potential candidates for a large number of applications such as separation of liquids and gases, as se…
The synthesis and systematic evaluation of the influence of lateral mono‐, di‐ and tetra‐fluorination of the terminal phenyl ring on mesomorphic properties in seven novel series of suitably fluoro‐substituted 5‐n‐alkyl‐5′‐(4‐n‐decyloxyphenyl)‐2,2′‐bithienyls is reported. Compared with their non‐fluorinated parent coun…
Complex permittivity has been determined for mixtures of ethyleneglycol-1,4-dioxane (EG-DX) with various concentrations in the frequency range from 100 MHz to 30 GHz at 25 degrees C by time domain reflectometry (TDR). A primary process with an asymmetric shape and a Debye-type small-amplitude high-frequency process ar…
We describe a procedure for the preparation of As-S-Se and As-Se-Te glasses with low contents of gas-forming impurities (hydrogen, oxygen, and carbon) via melting of extrapure-grade elements in an evacuated silica ampule and purification of the melt by chemical distillation. The impurity concentrations in the glasses…

Abstract The composition of altered volcanic ash of the Late Ordovician Kinnekulle bed was studied in geological sections of the Baltic Paleobasin. The composition of altered ash varies with paleosea depth from northern Estonia to Lithuania. The ash bed in shallow shelf limestones contains an association of illite-sme…
The field of nanoparticle‐polymer composites is attractive from the standpoint of integrating the key features of both polymers and nanoparticles into hybrid or composite materials. Nanocomposites geared towards electronic and photophysical targets comprise an intriguing subset of the field, and benefit from interdisc…
An iterative solution to nonlinear problems of time-periodic eddy currents is performed by directly using the time-harmonic content of the field quantities instead of time-domain techniques employing successive time steps. A linear sinusoidal steady-state field problem is solved to determine the magnetization harmonic…
To date there are potential chronology-based but not conclusive reasons to believe that at least some of the gadolinium complexes play a causative role in the pathophysiology of nephrogenic systemic fibrosis (NSF) or nephrogenic fibrosing dermopathy (NFD). Still, the exact pathogenesis and the risk for patients is unc…
Graphs are frequently used to describe the geometry and also the physicochemical composition of protein active sites. Here, the concept of graph alignment as a novel method for the structural analysis of protein binding pockets is presented. Using inexact graph-matching techniques, one is able to identify both conserv…
Gold (Au) nanowires (NW) have been synthesized by using mixtures of l -α-dipalmitoylphosphatidylcholine (DPPC) and various conventional surfactants (CS) of different polarities. The capping ability of the surfactant mixture has been quantitatively evaluated by using UV−vis, TEM, XPS, FTIR, and XRD studies. The synthes…
Abstract Electrochemical polarization and impedance spectroscopic (EIS) techniques were used to investigate the corrosion behavior of Ti‐5Al‐2Nb‐1Ta alloy in Hanks solution at different immersion periods (0 h, 120 h, 240 h and 360 h). The impedance spectra are fitted using a non‐linear least square (NLLS) fitting proc…
We investigate the magnetotransport properties of La0.7Ca0.3−xAgxMnO3 (0⩽x⩽0.3) polycrystalline films prepared by spray pyrolysis. The virgin La0.7Ca0.3MnO3 (LCMO) (x=0.0) film shows paramagnetic-ferromagnetic [insulator-metal (IM)] transition at TC∼260K (TIM∼245K). Ag doping induces appreciable enhancement in TC∕TIM…
The effect of the degree of deformation by high-pressure torsion (using five and ten revolutions of anvils) on the structure of niobium and its thermal stability under annealing has been studied using transmission electron microscopy. By deformation with five revolutions, nanocrystalline niobium with a grain size of a…
In present study, the feasibility of improving tribological performance of low carbon chromium steel by applying complex surface treatments which combines the method of Plasma electrolytic saturation (PES) is investigated. The different regimes of diffusion treatments on the surface affect the mechanical and tribologi…
