The field of nanotechnology is one of the most active areas of research in modern materials science. Nanoparticles are known as a stimulating agent for plant growth and the activation of metabolic processes in plant and animal organisms.This research was planned to evaluate the potential effect of iron-oxide (Fe 2 O 3…
Well-aligned ZnO nanostructures have been intensively studied over the last decade for remarkable physical properties and enormous applications. Here, we describe a one-step fabrication technique to synthesis freestanding ZnO nanorod/graphene/ZnO nanorod double heterostructure. The preparation of the double heterostru…
A planar waveguide in the Nd[Formula: see text]-doped fluorophosphate glass is fabricated by a 6.0 MeV C[Formula: see text] ion implantation at a low-fluence of [Formula: see text] ions/cm2. The fluence is close to that in semiconductor industry. The dark mode spectra are recorded by a model 2010 prism coupler. The en…
A class of graphene wound into three-dimensional periodic curved surfaces (``graphitic zeolites'') is proposed and their electronic structures are obtained to explore how the massless Dirac fermions behave on periodic surfaces. We find in the tight-binding model that the low-energy band structure around the charge neu…
Stromal cell-derived growth factor-1 (SDF1) is a chemokine that is over-expressed at sites of injury and is believed to play an important role in wound repair. At the cellular level, SDF1 regulates the mobilization and trafficking of endothelial progenitors that originate in the bone marrow and functionally contribute…
We propose a computational framework for the self-consistent dynamics of a microsphere system driven by a pulsed acoustic field in an ideal fluid. Our framework combines a molecular dynamics integrator describing the dynamics of the microsphere system with a time-dependent integral equation solver for the acoustic fie…
The equilibrium solubilities of the anti-inflammatory drug naproxen (NPX) in 2-propanol + water mixtures were determined at several temperatures from 298.15 to 313.15 K. The Gibbs energy, enthalpy, and entropy of solution and of mixing were obtained from these solubility data. The solubility was maximal in φ1 = 0.90 a…
The molecule of the title compound, [Mo4(μ2-C12H10OP2)4(μ3-O)4O4], exhibits point group symmetry 2 with the twofold rotation axis passing through two opposite P atoms. Each MoVatom is bridged by three O atoms resulting in an Mo4O4heterocubane core. In the crystal, weak C—H...O interactions may help to consolidate pack…
Abstract We design tunable waveguide bends filled with graphene-based anisotropic metamaterials to achieve a nearly perfect bending effect. The anisotropic properties of the metamaterials can be described by the effective medium theory. The nearly perfect bending effect is demonstrated by finite element simulations of…
The gel-mediated syntheses and crystal structures of [N'-(pyridin-2-ylmethylidene-κN)benzohydrazide-κ(2) N',O]tris(thiocyanato-κN)praseodymium(III) mono-hydrate, [Pr(NCS)3(C13H11N3O)2]·H2O, (I), and aqua(nitrato-κ(2) O,O')[N'-(pyri-din-2-ylmethylidene-κN)benzohydrazide-κ(2) N',O](thiocyanato-κN)neo-dym-ium(III) nitrat…
In the presence of a small molecular protic initiator, immortal ring-opening polymerization (ROP) of lactide (LA) is a highly efficient strategy to synthesize polylactide in a controllable manner, while using polymeric alcohol as an initiator has been less investigated. A series of polymeric alcohols (PS–OH) composed…
Qualitative transformations of spectra of Electron Paramagnetic Resonance, EPR, were found in KH2PO4 crystals grown from liquor with 10−5–10−1 wt. % of anatase TiO2 nanoparticles in comparison with nominally pure KH2PO4. The nanoparticles have larger segregation coefficient for prismatic parts of the crystals than for…
On the basis of ab initio calculations, we report the quantum phase transition from ferromagnet to topological insulator via lithiation of Mo intercalated epitaxial graphene on SiC(0001). The original Mo intercalated system is characterized by spin-polarized Dirac cones with the Dirac points locating above the Fermi l…
Fracture toughness of AZ31B magnesium alloy subjected to quasi-static loading was investigated by infrared thermography. The results showed that temperature evolution around the crack propagation path during fracture underwent three stages: initial steady stage, monotonic increase stage and final steady stage. The tem…
Abstract Two photodegradable heterobifunctional linkers (PHBL) connected by a N-(2-nitrobenzyl)imide structure have been developed as tools to obtain photodegradable diblock copolymers with precisely controlled molecular weight. They can undergo two different click reactions, i.e., Huisgen cycloaddition and Michael ad…
A repeatable and relatively simple recipe is developed to fabricate optical metasurfaces with three-dimensional gold nanostructures. The recipe avoids any directional etching processes and is particularly useful in the fabrication of gold suspended structures such as air bridges and mushrooms, since dry etching of gol…
An important issue concerning computer simulations addressed to free energy estimates via nonequilibrium work theorems, such as the Jarzynski equality [Phys. Rev. Lett. 1997, 78, 2690], is the computational effort required to achieve results with acceptable accuracy. In this respect, the dynamical freezing approach [P…
Nature of bonding in the NgBeS (Ng = Ar, Kr, Xe) molecules has been studied using topological analysis of ELF, ELI-D functions with the wave function approximated at the DFT (M062X, B3LYP + ZORA), MP2, CCSD and CASSCF level of calculations. Both Xe–Be and Be=S bonds display topological features typical for the covalen…
We report a two color monitoring of drug‐induced cell deaths using total internal reflection fluorescence (TIRF) as a novel method to determine anticancer activity. Instead of cancer cells, breast cancer stem cells (CSCs) were directly tested in the present assay to determine the effective concentration (EC50) values…
A multiple time scale relaxation dynamic is revealed by alternating current (ac) susceptibility studies of a single crystal of $\mathrm{E}{\mathrm{r}}_{2}\mathrm{T}{\mathrm{i}}_{2}{\mathrm{O}}_{7}$ performed at high temperatures (${k}_{B}T\ensuremath{\gg}J/{k}_{B}$) in a wide range of static magnetic fields. An analys…
