Composition spread alloy films (CSAFs) are combinatorial materials libraries that contain broad, continuous composition ranges of binary or higher-order alloys on a single, compact substrate. When characterized for composition and functional properties using spatially resolved methods, CSAF libraries enable rapid dete…
Abstract The polycarbonate/poly(acrylonitrile butadiene styrene) blends, (PC/ABS), are mainly degraded by sunlight known as photodegradation when exposed to outdoor conditions. It is the ultraviolet (UV) radiation that is responsible for the degradation of the blend. To stabilize against the harmful UV radiation and t…
Forced assembly processing provides a unique opportunity to examine the effects of confinement on block copolymers (BCPs) via conventional melt processing techniques. The microlayering process was utilized to produce novel materials with enhanced mechanical properties through selective manipulation of layer thickness.…
Diamond-like carbon (DLC) coatings were deposited on nearly equiatomic nickel-titanium (NiTi) alloy by arc-enhanced magnetron sputtering. The microstructure, surface morphology, chemical composition, surface free energy, protein adsorbance, and leach amount of Ni ions were assessed by Raman spectroscopy, high-resoluti…
We present new results for the Reverse Monte Carlo modeling of 0.35Na 2 O + 0.65[ x B 2 O 3 + (1 – x )P 2 O 5 ] glasses based on previously reported X-ray diffraction (XRD) data. Structural models have been generated that accurately reproduce the pair correlation functions and structure factors determined by XRD while…
The diffusion of CO 2 molecules on a reduced rutile TiO 2 (110)-(1×1) surface has been investigated using scanning tunneling microscopy (STM) and density functional theory (DFT) calculations. The STM feature associated with a CO 2 molecule at an oxygen vacancy (V O ) becomes increasingly streaky with increasing temper…
Abstract The creep properties, that is, the velocity constant, activation energy, stress index, and time index, of a test piece (TP) cut from a glass‐fiber‐reinforced nylon 6 product were successfully determined by a compression creep test. In the determination of the creep properties, the experimental creep curves fo…
Two proton-conductive molecular hybrid complexes, {[H(H2O)2][Sr(HINO)4(H2O)7(PW12O40)]} n (1) and {[H(H2O)2][Ca(HINO)4(H2O)5(PW12O40)]} n (2), were constructed by introducing alkaline-earth metal ions and [PW12O40]3– anions in the gallery of H-bonding networks based on isonicotinic acid N-oxide (HINO). Single-crystal…
Von dreieckig über ringförmig und hexagonal zurück zu dreieckig: Silber-Nanoplättchen wechseln während des durch dreieckige Gold-Kristallkeime induzierten Wachstums ihre Form, wobei die finale Dreiecksstruktur um 180° verdreht zu der der Keime ist (siehe Bild, der ursprüngliche dreieckige Goldkeim ist in der Mitte des…
Abstract The compound [Co(μ‐ox)(Hpmtz)] (Hpmtz = 5‐pyrimidyltetrazole, ox = oxalate) has been synthesized under hydrothermal conditions by reacting CoCl 2 · 6H 2 O with 2‐cyanopyrimidine and sodium azide. Both ox and Hpmtz ligands were generated in situ during the hydrothermal reaction. The structure of [Co(µ‐ox)(Hpmt…
OBJECTIVE: Paclitaxel-loaded poly(lactic-co-glycolic acid) (PLGA) nanoparticles incorporated with galactose-carrying polymer poly(vinyl benzyllactonamide) (PVLA) were prepared to facilitate the hepatocyte cell targeted delivery of paclitaxel via ligand-receptor mediated endocytosis. The factors impacting nanoparticle…
To improve the thermal properties and mechanical properties of synthetic biodegradable polymers, poly(butylene succinate) (PBS) and poly(hexamethylene isophthalamide- co -terephthalamide) (PA6IcoT) are reactively blended in a LIST corotating processor under melting conditions. The products are fractionated into insolu…
We study the effect of doping on the linear and nonlinear optical properties of Au 19 M clusters, M being the alkali metal atoms, Li, Na, K, Rb, and Cs, as well as the coinage metal atoms, Ag and Cu, by employing response theory within time-dependent density functional theory. We consider doping at both exohedral and…
A formal [2 + 2] cycloaddition-cycloreversion (CA-CR) between N,N'-dicyanoquinone diimides (DCNQIs) and electron-rich alkynes was explored, providing a new class of π-conjugated donor-acceptor chromophores. These DCNQI adducts exist in the solid state as single diastereoisomers, but as two interconverting diastereoiso…
We demonstrated an efficient sequential two-step near-infrared (NIR) quantum splitting (QS) in a Ho3+ singly doped β-NaYF4. An incident high-energy ultraviolet (UV)-to-visible photon in the wavelength range of 300−560 nm, which enables the Ho3+:5F4,5S2 states excited, could be efficiently split into two NIR photons at…
Single-crystalline CaFe${}_{2}$As${}_{2}$ and (Ca${}_{1\ensuremath{-}x}$Na${}_{x}$)Fe${}_{2}$As${}_{2}$ polycrystals (0 $x$ 0.66) are synthesized and characterized using structural, magnetic, electronic transport, and heat capacity measurements. These measurements show that the structural/magnetic phase transition in…
Abstract The effectiveness of compatibilizers in enhancing the dispersion of polypropylene (PP) at various molecular weights in recycled polyethylene terephthalate (RPET) was elucidated. The idea of incorporating PP of different molecular weights evolved from the intention of simultaneously recycling the PET bottles t…
This work demonstrates a polarization-independent electrically tunable Fabry-Pérot (FP) filter that is based on polymer-stabilized blue phase liquid crystals (PSBPLCs). An external vertical electric field can be applied to modulate the effective refractive index of the PSBPLCs along the optical axis. Therefore, the wa…
Abstract Highly conducting polypyrrole (PPY) films, doped with various anions [pTS − , ClO 4 − , and NO 3 − and mixed electrolyte system (pTS − + ClO 4 − )], have been electrochemically synthesized in aqueous solution at ∼275 K in an inert atmosphere. PPY exhibits metallic order dc conductivity at room temperature and…
Nanocrystals and nanoclusters of the room-temperature magnetic spinel CuCr(2)S(4) have been synthesized using a facile solution-based method. The synthesis involves hot injection of an excess of 1-dodecanethiol (1-DDT) into a boiling coordinating solvent containing CuCl(2) and CrCl(3)·6H(2)O. Using octadecylamine (ODA…
