In spite of decades of efforts, the puzzle of understanding the anomalies of liquid water remains unsolved. Several plausible theoretical scenarios have been proposed, but distinguishing among them requires accessing temperatures below the homogeneous nucleation temperature ${T}_{h}$, which for bulk water is an experi…
The accelerated ageing of cables for nuclear power plant was studied for the life evaluation in the environmental conditions. For the accelerated radiation ageing, the dose rate is the important point, because the oxidation profile in the insulation is much affected by dose rate due to oxygen diffusion limitation duri…
compounds to clarify the mechanisms of superconductivity in Fe-based compounds. We carry out first-principles density functional theory (DFT) calculations of structural, electronic, magnetic and transport properties and measure resistivity, Hall resistance and Seebeck effect curves. All the transport properties exhibi…
Success of adipose tissue engineering for soft tissue repair has been limited by insufficient adipogenic differentiation, an unfavorable host response, and insufficient vascularization. In this study, we examined how scaffold-free spheroid and fibrin-based environments impact these parameters in human adipose-derived…
New nano-scale drug carriers offer the possibility of increasing the therapeutic index of drug molecules by increasing their effectiveness, diminishing their toxicity against physiological tissues and achieving controlled therapeutic levels for a prolonged time. This review gives an overview of approaches to the devel…
The analysis of two-step spin crossover phenomena in one-dimensional systems is performed in the framework of Ising-type model by using Monte Carlo entropic sampling technique. Both short-range and long-range interactions are considered in the Hamiltonian which also takes into account different degeneracies between th…
The first-principles density functional calculation is used to investigate the electronic structures and magnetic properties of Mn-doped and N-co-doped ZnO nanofilms. The band structure calculation shows that the band gaps of ZnO films with 2, 4, and 6 layers are larger than the band gap of the bulk with wurtzite stru…
BACKGROUND: Colon cancer is one of the major causes of death in the Western world. Early detection significantly improves long-term survival for patients with the disease. Near- infrared (NIR) fluorescent nanoparticles hold great promise as contrast agents for tumor detection. NIR offers several advantages for bioimag…
The complex NMR study of the magnetic structure of LiCu2O2 multiferroic has been performed. It has been shown that the spin spirals in LiCu2O2 are beyond the ab, bc, and ac crystallographic planes. The external magnetic field applied along the c axis of the crystal does not change the spatial orientation of spirals in…
Noscapine, a tubulin binding anticancer agent undergoing Phase I/II clinical trials, inhibits tumor growth in nude mice bearing human xenografts of breast, lung, ovarian, brain, and prostrate origin. The analogues of noscapine like 9-bromonoscapine (EM011) are 5 to 10-fold more active than parent compound, noscapine.…
Abstract This paper focuses on the evaluation of thread interlacing and its influence on some of the end-use properties of woven fabric, especially its influence fabric thickness and roughness. Weaves and their interlacing structural models, different thread positions in the fabric, and thread compression in thread in…
We report here the strain dependent structural and electrical transport properties of epitaxial NdNiO3 thin films. Pulsed laser deposition technique was used to grow the NdNiO3 thin films on c-axis oriented SrTiO3 single crystals. Deposited films were irradiated using 200 MeV Ag15+ ion beam at the varying fluence (1 ×…
We introduce a setup and method to produce gold tips that are suitable for tip-enhanced Raman spectroscopy by using a single step constant current electrochemical etch. The etching process is fully automated with only three preset parameters: the etching current, the reference voltage and the immersed length of gold w…
Many drug delivery systems have indicated improvement in delivery of various drug molecules and among these biodegradable and biocompatible polymers such as poly(D,L-lactide-co-glycolide) (PLGA) have been shown to enhance intracellular uptake of drug candidates when formulated as nanoparticles. PLGA nanoparticles were…
The effect of reinforcing styrene butadiene rubber (SBR) with functionalized carbon nanotubes on the mechanical and thermal properties of the nanocomposite was investigated. Multi-walled carbon nanotubes (CNTs) were functionalized with phenol functional group to enhance their dispersion in SBR matrix. Surface function…
Abstract Carbon nanotubes and graphene have been fully dispersed in water using novel stimuli-responsive stabilizers derived from ionic liquid-based reactive surfactants. These stabilizers include nanolatexes and a new family of triblock copolymers. Our waterborne dispersions of fully exfoliated carbon nanotubes yield…
The sewing process is a manufacturing technology which presents severe challenges for automation. Due to variations in the material properties and unpredictable mechanical compliance, real-time sensor-based control strategies are necessary to achieve satisfying results. This paper presents a sewing cell consisting of…
Tetragonal-cubic phase transition has been investigated in relaxor-ferroelectric 0.85Pb(Zn1/3Nb2/3)O3-0.15PbTiO3 single crystal using dielectric and Raman spectroscopy. A detailed analysis of the dielectric data suggests that the transition is of second order. In the tetragonal phase (P4mm), all the modes predicted by…
This paper presents an analysis to determine the effect of the stress enhancement factor due to the presence of protrusions in the semiconductor shields of HVDC cables. The theoretical analysis of the electric field containing protrusions is based on a harmonic solution for the electric field for spherical and spheroi…
Nanoparticles of silver (nano-Ag) is an emerging alternative feed supplement for poultry and likely for medical applications. As a result of nanosilver special characteristic of killing bacteria, antimicrobial materials containing nanosilver are becoming increasingly important because of their wide range of applicatio…
