Highly oriented and large-scale ZnO nanorod arrays have been successfully synthesized on zinc foil by a simple, low-temperature, solution-phase approach. In this approach, was used not only as substrate but also zinc-ion source for the direct growth of arrays. X-ray diffraction (XRD) analysis, high-resolution TEM (HRTEM) images, selected-area electron (SAED) patterns indicated that structure single-crystalline grown in [0001] direction with wurtzite structure. The optical properties were...
Abstract Clay aerogels and poly(vinyl alcohol)/clay were prepared via an environmental friendly freeze‐drying process. Both mechanical properties microstructures of the clay polymer/clay correlated to freezing conditions. The compressive moduli these materials increased as temperature used produce was decreased. Scanning electron microscopic observations suggest that morphological variations can be explained by mechanism ice templating produced structures. © 2013 Wiley Periodicals, Inc. J....
Abstract The thermal and oxygen transport properties of a series thermoplastic polyurethanes (TPUs) based on 4,4′‐methylene diisocyanate (MDI) 1,4‐butanediol (BD) as hard segments, poly(tetramethylene glycol) (PTMG) or poly(butylene adipate) (PA) soft are studied. Oxygen permeabilities ( P ) both polyester‐based polyether‐based TPUs increase with decreasing segment fractions. solubility S diffusivity D can be derived from permeation curves. correlates the amount excess free volume determined...
Abstract Laminates of polymer/clay aerogels and glass fabric sheets were prepared with varying epoxy adhesion application levels. A poly(amide‐imide) an (1,4‐butanediol diglycidyl ether/2,6‐diaminopyridine) chosen as the two “foam core” polymers; both single‐layered double‐layered fiber laminates investigated. The between polymer clay fibers was quantified using T‐peel method. peel strength properties found to increase adhesive loading increased up optimal value, after which declines....
Fresh milk and sodium montmorillonite clay can be used to prepare foam-like materials via an environmentally sustainable freeze-drying process. The enzyme transglutaminase (Tgase) was demonstrated effective cross-linker; treatment of with Tgase contributed the formation a gel network. mechanical properties milk/clay composites after were greatly improved (e.g. compressive moduli increasing from 1·4 13 MPa). Milk beyond its expiration date also in this research, demonstrating that dairy...
The combination of high-brilliance x-ray sources, fast detector systems, wide-bandwidth networks, and parallel computers can substantially reduce the time required to acquire, reconstruct, visualize high-resolution three- dimensional tomographic data sets. A quasi-realtime computed microtomography system has been implemented at 2-BM beamline Advanced Photon Source Argonne National Laboratory. With this system, a complete set be collected in about 15 minutes. Immediately after each projection...
Yb3+-doped NaErF4 microcrystals exhibit red and green upconversion (UC) luminescence excited by 980 nm 1560 nm lasers, respectively. The luminous intensity in the region shows stronger under excitation than that excitation. Moreover, of eye-visible luminescences is increased after doping Fe3+ ion. In addition, ion endows with magnetic characteristics, realizing dual functions (optical magnetic). Furthermore, makes crystal structure easy to evolve. effects concentration molar ratio F:Ln on...

Here, we have identified the monolayer phase of Bi2O2Se as a promising two-dimensional semiconductor with ultra-high carrier mobility and giant electric polarization. Due to strong reconstruction originated from interlayer electrostatic force, applied structure prediction algorithms explore crystalline geometry lowest total energy. Considering Se Te belong same group, Bi2O2Te is also investigated based on similar scheme. Further calculations suggest that high maintained in moderate band gap...
