In this work we intend to study the thermodynamic and microscopic structural properties of Tl-Na liquid alloy at 673 K on the basis of regular associated solution model. We have estimated the mole fractions of the complex and the free monomers assuming the complex TlNα as energetically favoured in the initial melt. In…
Using amorphous oxide templates known as micro-crucibles which confine a vapor–liquid–solid catalyst to a specific geometry, two-dimensional silicon thin-films of a single orientation have been grown laterally over an amorphous substrate and defects within crystals have been necked out. The vapor–liquid–solid catalyst…
Abstract Integral cross sections of the reactions 46Ti(n, p)46Sc, 47Ti(n, p)47Sc, 48Ti(n, p)48Sc, 60Ni(n, p)60Co and 64Zn(n, p)64Cu were measured with fast neutrons (E n > 1.5MeV) from an Am/Be source. The results were compared with data calculated using the neutron spectral distribution and the excitation function of…
Abstract The radiolytic stability of different substituted diglycolamides such as N,N,N′,N′-tetrapentyl diglycolamides(TPDGA), N,N,N′,N′-tetrahexyl diglycolamide (THDGA), N,N,N′,N′-tetraoctyl diglycolamide (TODGA), N,N,N′,N′-tetradecyl diglycolamide (TDDGA) and N,N,N′,N′-tetra-2-ethyl hexyl diglycolamide (T2EHDGA) was…
Mesoporous CeO 2 was synthesized by the nanocasting pathway using the mesoporous SBA-15 silica as structure template and cerium nitrate as the CeO 2 precursor via a solid–liquid route. Ag / CeO 2 catalysts were prepared by three different methods: wetness impregnation (WI), deposition–precipitation with urea (DPU) and…
The article describes the results of studying complexes diatoms sediments of middle Sarmatian in the northern part of Black Sea region. Comparative analysis has been done of taxonomic composition of locality diatom complexes as a result of studies. This article contains information about the correlation remote section…
Three types of reflectors, including the distributed Bragg reflectors (DBRs), the first hybrid reflectors composed of DBR and Al mirror (DBR-Al), and the second hybrid reflectors composed of DBR, an additional low-refractive-index layer, and Al mirror (DBR-L-Al), were investigated by use of thin-film theory at the cen…
The interaction between dynamic drafting force and its variability with break draft and short term irregularity of carded cotton sliver has been discussed. Drafting force data have been collected from online draftometer, installed on break draft zone of cotton drawing frame. The results indicate that the dynamic draft…
Serial crystallography should be possible with a much wider range of radiation sources as Ayyer et al. [IUCrJ (2015), 2, 29-34] show that crystallographic intensities can be recovered from randomly oriented frames which are too sparse for indexing.
Electron‐acceptor units, combined with bithiophene substituted with flexible chains end‐functionalized with cross‐linkable moieties, provide soluble donor‐acceptor‐donor (DAD) π‐conjugated oligomer‐type molecules with cross‐linking ability and broad absorption in the visible spectrum. A study on the cross‐linking cond…
Hydrogenated amorphous carbon (a-C:H) films have been synthesized by a radio frequency plasma enhanced chemical vapor deposition (rf-PECVD) technique with different bias voltage from 0.0 to -0.5 kV. The Raman spectra displayed the polymer-like hydrogenated amorphous carbon (PLCH) film with 0.0 to -0.1 and a-C:H films…
The investigation of promising materials used as lead-free solders has been conducted for a long time. In this connection, special attention is paid to low-melting-point metals and alloys, however the search for optimal systems is still going on. The systems Ag-Sn due to excellent electronic conductivity are the most…
Plasma immersion ion implantation into fins and trenches at elevated pressures is simulated. In the present work we calculate boron concentration distribution in the sample accounting for ion scattering in plasma sheath and geometric shadowing effects (ions at certain angle of incidence couldn’t achieve shadowed part…
The magnetic susceptibilities χ of liquid Ti–Sn and V–Sn alloys on the Sn-rich side have only a weak and positive temperature dependence, which suggests that Ti and V ions in the alloys are in the nonmagnetic state. Similarly, the χ values for liquid Co–Sn and Ni–Sn on the Sn-rich side are also in the nonmagnetic stat…
Reactive adsorption desulfurization over metal oxides adsorbents was carried out to remove the sulfur of real fluid catalytic cracking gasoline and model gasoline in a batch reactor at low pressures in the presence of hydrogen. The results show that Ni appearing after reduction and higher temperature leads to a signif…

Ever growing resistance of pathogenic bacteria against the existing antibiotics has forced researchers to look for new methods and techniques to design effective antimicrobial agents. In the present study a new tetracycline-based antimicrobial polymer (AMP) was synthesized from tetracycline and methacrylic acid (MAAc)…
This work describes the development of different weight percentages of glycidyl functionalized mullite-reinforced caprolactam-toughened epoxy (MCEP) nanocomposites. The functionalization of mullite and MCEP are confirmed by Fourier transform infrared spectroscopic analysis. Further, the morphological, surface behaviou…
The authors measured the relative permittivity of SiO2 deposited with a focused Ga+ ion beam by creating small parallel plate capacitors on a gold substrate. The relative permittivity of SiO2 ranged from a low of 7.5 to a high of 10.5 depending on the deposition yield, Y, defined as the film volume per ion dose. Lower…
Influence of gas sorption and desorption on field emission current evolution from carbon nanotube cathodes was investigated. Two types of nanotube cathodes were made: nanotubes grown from gas phase on stainless steel and nanotubes deposited from solution on Si substrate. Exposure of cathode to air at atmospheric press…
