Microwave N2-Ar plasmas applied for N-graphene post synthesis
(Materials Research Express, 2018)
High level of nitrogen doping (∼25%) of free-standing graphene sheets was achieved using the remote region of a Ar-N2 microwave plasmas. The relation between the percentage of nitrogen in the plasma and the characteristics ...
First electrochemical investigation of organophosphorus pesticide azametiphos and its quantification using electroanalytical approach
(International Journal of Environmental Analytical Chemistry, 2018)
In this work, the electrochemical behaviour and the subsequent development of an analytical procedure for quantification of pesticide azamethiphos, using boron-doped diamond (BDD) electrode are reported for the first time. ...
Radiation effects on luminescent and structural properties of YPO4: Pr3+ nanophosphors
(Radiation Effects and Defects in Solids, 2018)
YPO4 phosphors doped with trivalent ion Pr3+ were prepared by sol–gel method and treated with different doses of gamma radiation, from 0.25 MGy to 4 MGy. Effects of radiation on morphology, structure and luminescent ...
Compact discrete breathers on flat-band networks
(Low Temperature Physics, 2018)
Linear wave equations on flat-band networks host compact localized eigenstates (CLS). Nonlinear wave equations on translationally invariant flat-band networks can host compact discrete breathers-time-periodic and spatially ...
A New Photocatalyst Bismuth Oxo Citrate: Synthesis, Characterization, and Photocatalytic Performance
(Water Environment Research, 2018)
A new photocatalyst bismuth oxo citrate was synthesized by facile precipitation process with calcination at 200 8C. The photocatalyst was characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), ...
Cooperation of intrathymic T15 idiotype-bearing B and complementary T cells in ontogeny of natural Treg cells involved in establishment of T15 clonal dominance
(Immunology Letters, 2018)
The mechanisms for dominant T15 idiotype selection are not well understood, yet the significance of idiotypic regulation has been suggested. We proposed that to become dominant V regions of a given subset of B-1a cell must ...
Chaotic dynamics and supercontinuum generation with cosh-Gaussian pulses in photonic-crystal fibers
(Laser Physics, 2018)
In this paper, we investigate broadband supercontinuum generation in photonic crystal fibers using cosh-Gaussian optical pulses, which provide flatter spectrum than standard Gaussian pulses. This fact can be crucial for ...
Fruit Wines Inhibitory Activity Against α-Glucosidase
(Current Pharmaceutical Biotechnology, 2018)
BACKGROUND: Fruit wines are well known for their profound health-promoting properties including both enzyme activations and inhibitions. They may act preventive in regard to diabetes melitus and other chronic diseases. ...
Experimental Investigation of Microstructure and Phase Transitions in Ag-Cu-Zn Brazing Alloys
(Journal of Materials Engineering and Performance, 2018)
Microstructure and phase transitions of selected brazing alloys from the Ag-Cu-Zn ternary system were investigated. Four ternary alloys with silver content in the compositional range from 25 to 60 wt.% were studied using ...
Use of acellular collagen matrix for the closure of the open oral wound in bone regeneration
(Journal of Stomatology, Oral and Maxillofacial Surgery, 2018)
Mucograft is collagen matrix was designed for use in open healing situations due to its compact outer layer. The technique presented in this article is an attempt to avail this attribute for covering open oral wound in ...
