Separation and Recovery of Platinum by Magnetic Core-shell Nano-structures Modified with N-(2-aminoethyl)-3-aminopropyltrimethoxysilane
In this paper, Fe 3 O 4 @SiO 2 core/shell magnetic nanostructure has been synthesized and modified by N-(2-aminoethyl)-3-aminopropyltrimethoxysilane (AEAPTMS). Fe 3 O 4 @SiO 2 was used as a novel adsorbent for separation of hexachloroplatinic acid.X-ray diffraction (XRD), scanning electron microscopy (SEM), and FT-IR…
Effects of Kneading Concentration on Characteristics of HwBKP Fibers
In this study, effects of kneading concentration on characteristics of hardwood bleached kraft pulp (HwBKP) fibers were elucidated. A laboratory two-shaft kneader was utilized for kneading. Kneading concentration was varied in the range of 15-30% (w/w) and the number of kneading treatment was adjusted between 0 and 6…
Preparation of Electro-deposited Ni-Mo-Al Coating and Its Properties
Ni-Mo-Al coatings were prepared on Ni alloy by electrodeposition method. The effects of current density, frequency, duty cycle and electrodeposition time on mass percentages of Al of Ni-Mo-Al coatings were researched, respectively. The properties of wear weight loss and friction coefficients were investigated respecti…
Evolution of the defect subsystem of structural steel with bainite structure on deformation
Transmission electron diffraction microscopy permits analysis of the evolution of the defect subsystem in 30X2H2MΦA steel with bainite structure, with up to 36% compression. The influence of the deformation on the scalar dislocation density, the volume of the material with microtwins, the fragment dimensions, the numb…
Interaction of Fe–Al–Cr–C with the melt of an alkali metal carbonate
The interaction of an Fe–Al–Cr–C (29.5 wt % Fe, 29.35 wt % Cr, 2.56 wt % C, 38.59 wt % Al) alloy with the melt of a lithium, sodium, or potassium carbonate containing 1–5 wt % addition to a salt phase is studied by gravimetry and measuring the corrosion potential and anode polarization curves in the temperature range…
Kinetics of the emergence of temporal order in γ-irradiated crystals of BiFeO3
The process of oscillation in displacing atoms upon irradiation with γ-quanta (with energies up to 55 MeV) is observed for the first time in a class of insulators. The object of study is multiferroic BiFeO 3 , the oscillating period is ∼40 days, and the physical cause of the phenomenon is oscillating local pressure. T…
Modulation of cellular responses: The two-photon polymerization approach in the control of the physical micro/nanoenvironment
Cells and tissues are extremely sensitive to their physico-chemical surroundings: in regenerative medicine, as an example, the maintenance of culture conditions resembling the in vivo environment is essential for a correct tissue development. In this review, we summarize our results concerning the preparation and test…
Passive reduced order macromodeling using hamiltonian matrix pencil perturbation
In this paper, a method for obtaining a reduced order macromodel based on measured parameters is presented. Loewner Matrix based macromodeling may require a higher than optimal system order in order to preserve the passivity of the macromodel. In this paper, a modified order selection scheme, combined with the Hamilto…

Advanced design of a low energy electron source
A multiphysics-based modeling design of a low energy electron source using a thermionic cathode is described in this paper. The proposed device produces a narrow beam employable in delicate applications where dimensions are critical. The effects of multiple physics influencing factors due to the cathode heating over t…
Nonlinear Absorption And Scattering In Wide Band Gap Silver Sulfide Nanoparticles Colloid And Their Effects On The Optical Limiting
In this paper, we study the optical nonlinearities of Silver sulfide (Ag2S) nanostructures dispersed in the Dimethyl sulfoxide (DMSO) under exposure to 532 nm, 15 nanosecond (ns) pulsed laser irradiation. Ultraviolet–visible absorption spectrometry (UV-Vis), X-ray diffraction (XRD), and transmission electron microscop…
Interstellar dust modelling: Interfacing laboratory, theoretical and observational studies (The THEMIS model)
Abstract The construction of viable and physically-realistic interstellar dust models is only possible if the constraints imposed by laboratory data on interstellar dust analogue materials are respected and used within a meaningful theoretical framework. These “physical” dust models can then be directly compared to ob…
Investigation of the electrical and chemical processes causing the failure event in a copper sulfide related transformer failure
Copper sulfide related failures of oil-filled plants have become more common around most parts of the world over the last couple of decades, which has led the industry to re-evaluate their asset risk analysis policy for mineral oil insulated power assets. Two main theories for the failure event suggested by the curren…
Surface plasmon polaritons of a symmetric metamaterial slab waveguide with a hollow core for fluid sensing
We present a novel waveguide-type fluid sensor with symmetric metamaterial (MTM) slabs by using surface plasmon polaritons (SPP). The presented fluid sensing slabs, consisting of MTM claddings and a hollow core, are designed to have the SPP mode enhance the sensitivity of the fluid sensor. SPP modes are surface waves…
Theoretical study of interactions between striated cylindrical particles and membrane
The interaction of nanoparticles with cell membranes is of great importance because of their potential biomedical applications. In this paper, we investigate the adhesion of stripe-patterned cylinders to a fluid membrane with a full consideration of the Helfrich free energy. Three situations are considered: one striat…
