An investigation into the ignitions and combustions of porous silicon (PS) nanoenergetic material array chips (nECs) at different ignition voltages was performed. The PS nECs were fabricated by integrating PS nanoenergetic material (nEMs) matrices and Cr-microbridges (microigniters) on the surface of silicon substrate…
We use transport, inelastic neutron scattering, and angle-resolved photoemission experiments to demonstrate that the stoichiometric LiFeAs is an intrinsically electron-overdoped superconductor similar to those of the electron-overdoped NaFe${}_{1\ensuremath{-}x}{T}_{x}$As and BaFe${}_{2\ensuremath{-}x}{T}_{x}$As${}_{2…
The dispersive and conductive properties of polymer nanocomposites are investigated simultaneously using the molecular dynamics simulation method. Four factors influencing the dispersion and conductivity are concerned, including polymer-nanoparticle interaction, nanoparticles with grafted chains, cross-linking of poly…
Reductive debenzylation of hexabenzylhexaazaisowurtzitane (HBIW) was carried out using palladium hydroxide deposited on activated carbon catalyst. The catalyst has been characterized using a nitrogen adsorption/desorption isotherm, a hydrogen isotherm, scanning electron microscopy (SEM), and transmission electron micr…
A bacterial cellulose mat was used as a template for the fabrication of conductive photoswitchable hybrid nanopaper by the incorporation of sol-gel synthesized vanadium nanoparticles. The resulting nanopaper, prepared through a green pathway, was able to photoinduce a reversible color change. Conductive properties at…
Gold nanorods that have an absorption band in the near-infrared region and a photothermal effect have been used as nanodevices for near-infrared imaging and thermal therapy. Choice of the optimal shape of gold nanorods which relates optical properties and in vivo biodistribution is important for their applications. In…
Paramagnetic chemical exchange saturation transfer (PARACEST) complexes are exogenous contrast agents that have great potential to further extend the functional and molecular imaging capabilities of magnetic resonance. As a result of the presence of a central paramagnetic lanthanide ion (Ln(3+) ≠ La(3+) , Gd(3+) , Lu(…
A new method for extracting discrete equilibrium data from a set of dynamic column breakthrough experiments is described. Instead of the classical approach where an isotherm model, i.e., a function, is used to describe the equilibrium, this approach represents the isotherm as a set of discrete points. For a given set…
Abstract Transparent monoliths of urea cross‐linked tripodal siloxane‐based hybrids, named tri‐ureasils, were prepared by the sol–gel process, using a wide concentration range of hydrochloric acid catalyst (1.0 × 10 –3 ≤ [HCl] ≤ 2.0 M ). The gelation time of the monoliths was controlled by varying the amount of water…
Atomistic molecular dynamics simulations in chloroform and solvent-free environments are used to build and study a homologous series of neutral dendronized linear polymers (DPs), whose repeat units are regularly branched dendrons of generations g = 1–7, excluding g = 5. We find that a DP with g ≤ 4 displays an elongat…
This study investigates the effects of filler loading on the properties of rattan powder-filled polypropylene composites. The composites were prepared by incorporating rattan powder of average size 180 m into polypropylene matrix using a Polydrive Thermo Haake internal mixer. Filler loadings of the rattan powders rang…
The effect of seeds in templating the morphology of peptide aggregates is examined using molecular dynamics simulations and a coarse-grained peptide representation. Varying the nature of the aggregate seed between β-sheet, amorphous, and β-barrel seeds leads to different aggregation pathways and to morphologically dif…
AFM force measurements have been performed to study the influence of the pH value and salt concentration on the interactions between poly(2-vinyl pyridine) brushes and microsized silica spheres, focusing on attractive and adhesion forces. It was found that the interaction was composed of a repulsive component reflecti…
Mechanochemical treatment of Serbian kaolin clay was carried out in a planetary ball mill using two different milling media, hardened steel or zirconia vials and balls. The samples obtained with various milling times were characterized by the particle size laser diffraction (PSLD), X-ray diffraction (XRD), differentia…
The interplay between crystallization and phase separation has been intensively studied recently. In this study, we extended the research into a dynamically asymmetric blend composed of amorphous poly(methyl methacrylate) (PMMA) and crystalline poly(ethylene oxide) (PEO). The large dynamic asymmetry induces network st…
Silicon carbide (SiC) has unique chemical, physical, and mechanical properties. A factor strongly limiting SiC-based technologies is the high-temperature synthesis. In this work, we provide unprecedented experimental and theoretical evidence of 3C-SiC epitaxy on silicon at room temperature by using a buckminsterfuller…
Ordered arrays of Ni and Co nanowires and nanotubes, with diameters between 30 nm and 60 nm, were prepared by electrodeposition into nanoporous alumina templates. The study of the corresponding magnetization reversal processes was performed by analyzing the angular dependence of coercivity (H c ) and using a simple an…
We demonstrate a facile chemical approach for fabricating Nd–Fe–B nanoclusters through oxygen bridging. The Nd–Fe–B nanoclusters comprised of small aggregated particles (∼2 nm diameter) could be successfully synthesized using sodium borohydride, a conventional reducing agent. The three-step process consists of the for…
Abstract Reduced critical electric field strength ( E / N ) cr is an important indicator for the evaluation of dielectric breakdown of SF 6 and its mixtures. This paper aims to analytically investigate the dielectric breakdown properties of SF 6 –N 2 mixtures. First, ( α − η )/ N and ( E / N ) cr of SF 6 –N 2 mixtures…
We report on the first observation of optically excited surface plasmon polaritons (SPPs) in the conducting phase of vanadium dioxide (VO(2)) thin films. VO(2) is low-loss optical material that undergoes an insulator-metal transition (IMT) under suitable thermal, optical, or electrical stimulation, thus enabling tunab…
