Raman spectroscopy study of carbon-doped resorcinol-formaldehyde thin films
(Physica Scripta, 2013)
In this work, we investigated the properties of carbon resorcinol-formaldehyde (RF) cryogel thin films. RF cryogels were doped by single-wall carbon nanotubes, graphene and graphene quantum dots. The structure of the ...
Relations between scaling-transformed Husimi functions, Wigner functions and symplectic tomograms describing corresponding physical states
(Physica Scripta, 2011)
Husimi Q-functions are the only functions from the class of Cohen quasi-distributions on phase space that after scaling transformation (q, p) - GT (lambda q, lambda p) remain in the same class when the modulus of the scaling ...
Gamma ray-assisted irradiation of few-layer graphene films: a Raman spectroscopy study
(Physica Scripta, 2014)
This paper represents results of a Raman spectroscopy study of gamma-irradiated few-layer graphene thin films at three different doses: 25, 50 and 110 kGy. Graphene thin films were deposited by the vacuum filtration method ...
Semiconductor nanoparticles in poly((2-dimethylamino)ethyl methacrylate-co-acrylic acid) co-polymers
(Physica Scripta, 2013)
Nanostructured cadmium selenide (CdSe) and lead sulfide (PbS) semiconductors were prepared in a poly(2-(dimethylamino)ethyl methacrylate-co-acrylic acid) matrix. The obtained nanoparticles were characterized by using optical ...
Fibre-grating sensors for the measurement of physiological pulsations
(Physica Scripta, 2013)
Mechanical physiological pulsations are movements of a body surface incited by the movements of muscles in organs inside the body. Here we demonstrate the use of long-period grating sensors in the detection of cardio-vascular ...
Evanescent-wave optical gas sensor with a porous thin-film coating
(Physica Scripta, 2014)
In this paper, we present the analysis and numerical model of absorptive gas detection by an optical evanescent-wave sensor. We investigate the influence of sensor geometry and thin-film porosity on the attenuation of ...
Vortex complexes in two-dimensional optical lattices linearly coupled at a single site
(Physica Scripta, 2013)
We investigate the stability and dynamical properties of complexes consisting of two identical vortices with topological charges S = 1 and 2 in the system of two linearly on-site-coupled two-dimensional (2D) vortices. The ...
Structural properties of composites of polyvinylidene fluoride and mechanically activated BaTiO3 particles
(Physica Scripta, 2013)
Nanocomposites of electroactive ceramics and ferroelectric polymers exploit favorable features of the matrix polymer and the nanostructured filler to produce new functional materials for pressure and IR sensors. In this ...
Raman spectroscopy of graphene nanoribbons synthesized by longitudinal unzipping of multiwall carbon nanotubes
(Physica Scripta, 2014)
Graphene nanoribbons (GNRs) were synthesized by longitudinal unzipping of multiwall carbon nanotubes (MWCNTs), and changes in Raman spectra were followed. Transmission electron microscopy was used to investigate the ...
Monolayer graphene films through nickel catalyzed transformation of fullerol and graphene quantum dots: a Raman spectroscopy study
(Physica Scripta, 2014)
In this paper we present synthesis of monolayer graphene islands. These films are deposited through nickel catalyzed transformation of fullerol and graphene quantum dots. Carbon doped nickel films are produced by autocatalytic ...
