Abstract A set of organically modified clays (OLS) were mixed with different compatibilizers to alter their interactions with either homopolymer or heterophasic polypropylenes when they were melt‐mixed, and the relation between the OLS/compatibilizer system and the composite morphology was studied. X‐ray diffraction (…
The complex interactions of two and three spark-generated bubbles are studied using high speed photography. The corresponding simulations are performed using a 3D Boundary Element Method (BEM) code. The bubbles generated are between 3 to 5 mm in radius, and they are either in-phase or out-of-phase with one another. Th…
Abstract The structure and mechanical properties of injection‐molded polypropylene along the flow direction were investigated in this article. A remarkable difference was found in morphology and mechanical properties of the injection‐molded parts along the flow direction. The three‐layered structure (namely the skin,…
Abstract Bast fibers from stems of kenaf ( Hibiscus cannabinus , L.), a warm‐season tropical herbaceous annual plant, were dispersed into poly‐ L ‐lactide (PLLA) matrix by melt‐mixing followed by compression molding. Low fiber fractions (1–5%) were investigated. The composites showed a slight lowering of thermal stabi…
Thymidylate synthase (TS) is an enzyme that catalyzes a complex cascade of reactions. A theoretical study of the reduction of an exocyclic methylene intermediate by hydride transfer from the 6S position of 5,6,7,8-tetrahydrofolate (H(4)folate), to form 2'-deoxyuridine 5'-monophosphate (dTMP) and 7,8-dihydrofolate (H(2…
Abstract To fully utilize the resource in the municipal solid waste (MSW) and improve the strength and toughness of wood plastic composites, glass fiber (GF)‐reinforced wood plastic hybrid composites (GWPCs) were prepared through compounding of recycled high‐density polyethylene (HDPE) from MSW, waste wood fibers, and…
Immersion freezing with the aid of power ultrasound prior to freeze drying of edamame was investigated. The effect of power ultrasound on the freezing rate was influenced by ultrasonic power, exposure time to ultrasound field, and the pulse duration of the ultrasound that was applied. The higher the ultrasound power a…
The synthesis and degradation of biopolymers are cardinal reactions that take place to maintain homeostasis in biosystems. Fundamental biological reactions can be reproduced in vitro by means of enzyme-mediated processes. Recently, bioprocesses have been extensively adopted to synthesize representative biopolymers, in…
Techniques to regenerate the vasculature have risen considerably over the last few decades due to the increased clinical diagnosis of artery narrowing and blood vessel blockage. Although initially re-establishing blood flow, current small diameter vascular regenerative materials often eventually cause thrombosis and r…
Brain is a delicate organ, isolated from general circulation and characterized by the presence of relatively impermeable endothelial cells with tight junctions, enzymatic activity and the presence of active efflux transporter mechanisms. These formidable obstacles often block drug delivery to the brain across the bloo…
In order to quantify the effect of temperature on the mechanical properties of hemp fiber polypropylene composites, formulations containing 25% and 40% (by weight) hemp fiber were produced and tested at three representative temperatures of 256, 296, and 336 K. Flexural, tensile, and impact tests, as well as dynamic me…
We report experimental investigations of the effects of microstructural defects and of disorder on the properties of 2D electron gases at oxide interfaces. The cross section for scattering of electrons at dislocations in LaAlO(3)/SrTiO(3) interfaces has been measured and found to equal approximately 5 nm. Our experime…
In this work, porous alumina is used as a template for electrochemical deposition of iron nanowires. Arrays of hexagonally ordered iron nanowires with a monodisperse diameter size of about 55 nm ± 2 nm and ranging from 0.3 to 1 μm in length have been fabricated by alternating current (AC) electrochemical reduction of…
As one of the most investigated organic compounds, phthalocyanines (Pcs) exhibit a stronger optical limiting response that can be used to protect human eyes, optical elements, and sensors from intense laser pulses, however, they tend to aggregate at high concentration. This aggregation usually adds relaxation pathways…
Strong magnetoelectric (ME) interaction was demonstrated at both dc and microwave frequencies in a novel Zn 0.1 Fe 2.9 O 4 /PMN–PT (lead magnesium niobate–lead titanate) multiferroic heterostructure, which was prepared by spin-spray depositing a Zn 0.1 Fe 2.9 O 4 film on a single-crystal PMN–PT substrate at a low temp…
The thermal conductances across covalently bonded interfaces between oriented single crystal diamond and completely aligned polyethylene chains are determined for the three principal orientations of diamond. The calculated thermal conductances, which range over 690-930 MW m(-2) K(-1), are consistent with those of othe…
Mass uptake of water vapor was measured as a function of relative humidity for indomethacin glasses prepared using physical vapor deposition at different substrate temperatures. Highly stable glasses were produced on substrates at 265 K (0.84Tg) by depositing at 0.2 nm/s while samples similar to melt-cooled glasses we…
Changing the composition and structure of a bimetallic surface system modifies its electronic properties and thus its catalytic activity. On the basis of density functional theory calculations, the electronic factors underlying the modified properties of bimetallic surfaces such as overlayer systems and, in particular…
We introduce an innovative and robust method for the preparation of nanocomposite multilayers, which allows accurate control over the placement of functional groups as well as the composition and dimensions of individual layers/internal structure. By employing the photocross-linkable polystyrene (PS-N(3), M(n) = 28.0…
Superconductivity in iron pnictides is studied by using a two-orbital Hubbard model in the large U limit. The Coulomb repulsion induces an orbital-dependent pairing between charge carriers. The pairing is found mainly from the scattering within the same Fermi pocket. The interpocket pair scatterings determine the symm…
