We have studied the electronic characteristics of FeCl3 intercalated bilayer graphene under a perpendicularly applied electric bias. Evolution of the electronic structure of FeCl3 intercalated bilayer graphene as a function of the applied electric bias is performed using first-principles density-functional theory incl…
Magnetic and luminescent bifunctional divalent europium nanocrystals (Eu(2+) NCs) are a promising class of novel advanced materials that have various applications in magneto-optic devices, catalysis, bioimaging, and solar cells. In the past few decades, much work has been carried out to study the synthesis, properties…
Quasi-crystals shocked the crystallographic world when they were reported in 1984. We now know that they are not a rare exception, and can be found in many alloy systems. One of the richer systems for quasi-crystals and their approximants is Al-Co-Ni. A large series of pseudo-decagonal (PD) approximants have been foun…
As one of the most common cancers, colorectal cancer (CRC) is a major public health issue worldwide. Thus, the identification of novel biomarkers to aid in the early diagnosis of CRC is crucial. The aim of the present study was to identify a novel protein biomarker for CRC, and to identify its structure. In this study…
Employing open-ended carbon nanotubes (CNTs) with and without hydrogen termination, we study the length scaling of metal-CNT contact resistance and its correlation with chemical bonding from first principles. Both models similarly show a transition from the fast-growing short-length scaling to the slow-growing long-le…
In this contribution, we present a review on the various bulk piezoelectric ceramic transformers based on planar vibration modes. The studied transformer shapes include rectangular bar, rings and discs (e.g. disc ring dot) homogeneously poled in the thickness direction. Electrical parameters like transformation ratio,…
Abstract Vertically well‐aligned ZnO nanowire (NW) arrays were synthesized directly on Si(100) substrate without any metal catalysts by conventional thermal evaporation. The effects of the substrate positions on the structures and properties of ZnO NW arrays were primarily discussed. The orientation and morphology of…
In this paper, starting with the Maxwell equations and the corresponding nonlinear wave equation, we derive a pulse evolution equation for a metamaterial with cubic (Kerr) nonlinearity. The given model equation goes beyond the commonly employed slowly evolving wave approximation (SEWA). The dispersive properties of th…
We prepared 5 different fractions of nanoparticles from the gold scrap, by using a new technology, Ultrasonic Spray Pirolysis (USP). The aim of this study was to characterize the microstructure and cytotoxicity of the nanoparticles along with their immunomodulatory properties, using Concanavaline A (ConA)-treated rat…
In conventional milling, appropriate coatings can be used on tools to enhance their cutting performance and efficiency of the production process. In an effort to improve the tooling performance in micro-scale milling, nano-crystalline diamond films were applied on a micro-end mill by a hot filament chemical vapour dep…
N-type ZnO samples have been implanted with MeV Zn+ ions at room temperature to doses between 1×108 and 2×1010cm-2, and the defect evolution has been studied by capacitance-voltage and deep level transient spectroscopy measurements. The results show a dose dependent compensation by acceptor-like defects along the impl…
Rhombohedral phase relaxor-PbTiO(3) solid solution single crystals poled along [011](c) exhibits superior lateral extensional piezoelectric response, which enables the excitation of a pure low frequency flexural mode with a bridge-type electrode configuration. For the ternary 0.24Pb(In(1/2)Nb(1/2)) O(3)-0.46Pb(Mg(1/3)…
The structural characteristics of fully-hydrogenated carbon and boron nitride mono- and multilayer slabs, together with nanotubes derived from the slabs, are investigated mainly by means of periodic local second-order Møller-Plesset perturbation (LMP2) calculations and the results are compared with Hartree-Fock (HF),…
Abstract Industrial robots are widely used in thermal spraying operations in order to assure process accuracy and reproducibility, as well as to increase worker´s safety. Robot path planning for the coating of free form geometries keeping constant the kinematic parameters can lead to complex robot paths and in some ca…
Chovanite, a new representative of the group of oxysulphosalts of Pb and Sb was found in three hydrothermal deposits of antimony ore, Dúbrava, Malé Železné, and Klačianka, situated on the northern slopes of the Low Tatra Mountains, Slovakia. It is associated with other Pb–Sb sulphosalts, especially boulangerite, robin…
Binary polar semiconductors in the wurtzite structure can be grown in the form of nanorods aligned along the wurtzite [0001] direction. In such structures, very large dipole moments have been observed experimentally. We have studied the distribution of charge in GaAs nanorods, so as to elucidate the origin of the dipo…
High-resolution Laplace deep-level transient spectroscopy (LDLTS) and thermal admittance spectroscopy (TAS) have been used to determine the effect of boron (B) concentration on the electronic states in polycrystalline chemical vapour deposition diamond thin films grown on silicon by the hot filament method. A combinat…
Drug safety for human body should be carefully studied for its potent clinical application. In this report, the neurotoxicity of anticancer drug daunorubicin (DNR) and the oleic acid-capped Fe3O4 nanoparticles (NPs) for rat brain was firstly explored by using the in vivo microdialysis. The results indicated that the a…
A facile one-pot water-in-oil microemulsion method has been developed for the synthesis of a novel core-shell Ag-graphene@SiO2 nanocomposite with fluorescein isothiocyanate (FITC) doped in the shell. During the preparation process, reducing both Ag+ and graphene oxide, and loading of Ag nanoparticles on graphene were…
Large-pore ethenylene-bridged (-CH═CH-) and phenylene-bridged (-C(6)H(4)-) periodic mesoporous organosilicas (PMOs) with face-centered-cubic structure (Fm3m symmetry) of spherical mesopores were synthesized at 7 °C at low acid concentration (0.1 M HCl) using Pluronic F127 triblock copolymer surfactant in the presence…
