Atmospheric pressure dielectric barrier discharges (DBDs) sustained in packed bed reactors (PBRs) are being investigated for remediation of toxic gases, CO2 removal and conversion of waste gases into higher value compounds. Though investigated extensively in experiments, few computational studies of PBRs have been per…
The known technology for producing fullerene membrane was applied to the natural carbon material. The basic structural elements of shungite carbon have been identified in the prepared nanostructured sample by optical methods.
We discuss the novel idea for direct terahertz pulse stimulated emission in the MPO4(M = Nd3+, Dy3+) rare-earth doped nanocrystals as a result of transitions between crystal-field (Stark) levels of the Nd3+and Dy3+manifolds.
Two dimensional(2D) materials such as graphene and transition metal dichalcogenides(TMDs) are exciting candidates for electronic and optoelectronic device applications. In particular, there is growing interest in stacked 2D materials that often arise naturally, and also provide added possibilities for desired function…
Graphene Nanoribbons (GNR) are been being investigated as they possess a bandgap in contrast to graphene sheets which have zero bandgap [1, 2]. Therefore, GNR might be more suitable as a channel material in field-effect transistors (FETs) which requires a high on/off ratio. The other electrical properties of GNR FETs…
Heterostructures based on the InSb quantum dashes buried into the InAs unipolar matrix exhibited the electroluminescence near 3.62 μm at room temperature. Use of the multi-component InAsSbP matrix layers lattice-matched with the InAs substrate allows to control the matrix surface chemistry and to determine the shape o…
This report surveys the effect of nanofiller characteristics on nanocomposites fabricated with two polyimide matrices. Mechanical and electrical properties were determined. Microscopy results showed that matrix chemistry, nanofiller characteristics and processing conditions had significant impact on nanocomposite qual…
The most widely used glue in a corrugator is starch, which is a natural polymer. This material needs thermal energy to achieve a binding force, so a heating section is installed in a corrugator. However, this heating section can cause quality problems in linerboards and corrugating medium and increase the production c…
The ferrite circulator is a kind of microwave devices which is complex-shaped and composed of both metal and dielectrics. It is time-consuming to compute the accurate threshold of multipaction discharge in ferrite circulators with particle-in-cell simulation or Monte Carlo simulation.
Study of phase composition, morphology and up-conversion luminescence of ytterbium- and erbium-doped barium and calcium fluoride nanopowders has revealed the influence of their synthetic conditions on their up-conversion luminescence energy yields.
We investigated the subjective comfort of mold brassieres for small-breasted women in terms of mechanical properties and thickness of polyurethane(PU) foams used. Experimental mold brassieres were manufactured using various PU foams with different thicknesses. To analyze the relationship between comfort and the mechan…
Experimental and numerical data on Stokes generation under the spectrally-limited nanosecond pulse excitation are collated to find the steady-state Raman gain coefficients. The approach is tested for barium nitrate. For potassium-gadolinium tungstate, the coefficients values of 14±3 and 11±3 cm/GW are determined in th…
Monolayer MoS₂ is energetically most stable when it has a 1H phase, but 1H to 1T phase transition (1H→1T) is easily realized by various ways. Even though magnetic moment is not observed during 1H→1T, 0.049 μ B /MoS₂ is obtained in local 1T phase; 75% 2H and 25% 1T phases are mixed in (2 × 2) supercell. Most magnetic m…
The study of morphological changes in transplanted liver tumors of rats after plasmonic photothermal therapy (PPTT) was conducted. The gold nanorods (GNs) functionalized with polyethylene glycol were injected by one-, two- and three-step intravenous administration. A day after injection tumors were irradiated by the N…
The paper presents a simplified method for modelling non-linearity of the magnetic circuit of the power transformer. The saturation effect is implemented by describing the self and mutual inductances as a function of the magnetic flux. The most important element of this function is the saturation coefficient which is…
The goal of the Underground Feeder Rehabilitation Program is to continually assess and maintain all underground cables within the Province of Manitoba to ensure the continual operation of the underground electrical distribution system. To do this, Distribution Asset Maintenance (DAM) works closely with Insulation Test…
Cobalt nanoparticles with high quality crystal structure and spin polarization support an excellent plasmon resonance at about 275 nm, which is comparable with gold nanoparticles. The quality of plasmon resonance is highly correlated with the superparamagnetic response of the isolated nanoparticles and disappeared in…
Summary form only given. In this paper we report the synthesis of nitrogen functionalized vertical graphene (N-VG) on nickel foam and silicon substrates using radio frequency plasma enhanced chemical vapor deposition (RF-PECVD) system. Two different environmental friendly green plasma approaches were adopted where we…

Coupled plasma-liquid systems are at the heart of several burgeoning applications in low-temperature plasma science, including biomedicine, biological and chemical disinfection, agriculture, and others. In order to realize the full potential of these applications, the basic underlying physical…
