Part 1 Introduction: Recent advances in polymer processing: the state of the art, new challenges and opportunities Non-Newtonian fluid mechanics and polymer rheology Polymeric materials: elastomers, plastics, fibers, composites, nanocomposites and blends Compounding and mixing of polymers Screw extrusion in polymer pr…
Metal cation (metal = Cu, In and La) ion exchanged ZSM-5 zeolites as catalysts for the NO selective reduction by propane and propene in excess oxygen. The surface reactions of HC-SCR over catalysts were investigated through in situ DRIFTS method. For C3H8-SCR, adsorbed nitrate species (–NO3) were observed as main reac…
The pressure induced phase transitions of TiO 2 from anatase to columbite structure and from rutile to columbite structure and the temperature induced phase transition from anatase to rutile structure and from columbite to rutile structure are investigated by ab initio plane-wave pseudopotential density functional the…
The comfort of textile materials has been the focus of many investigations since the concern for personal well-being and improving the quality of life started to become an important issue. The aim of this paper is to simulate water vapour transfer through knitted fabrics under different environmental conditions. In th…
Informations of phosphorus fractions are important for evaluation of their status in soil and understanding of soil chemistry that influence soil fertility. To obtain such information, amount and distribution of P in different fractions of 20 soil samples of Qazvin province, Iran were determined by sequential extracti…
A new organogelating moiety, 1, is proposed as a suitable and versatile building block for the production of other gelling compounds. Linking 1 with several different molecular fragments afforded new gels with different properties. A detailed investigation of the ferrocene substituted gelator is reported in this study.
To develop a forging process for high strength Mg-Zn-Y alloys with a long period stacking ordered (LPSO) structure, the forgeability and flow stress of Mg97Zn1Y2 (at%) alloys were investigated with the upsettability test at an initial strain rate of 0.55 s−1. As-cast and extruded Mg97Zn1Y2 alloys can be successfully f…
An original design of a fluorescent dithienylethene (DTE)-based bipyridine, where donor (D) and acceptor (A) groups are located on the same thiophene ring of the DTE unit, is reported; in non-polar solvents, UV or visible excitation triggers a photochromic reaction, disrupting the conjugation and quenching the fluores…
Uniform octahedral LuVO4 microcrystals have been successfully prepared through a designed two-step hydrothermal method. One-dimensional lutetium precursor was first prepared through a simple hydrothermal route. Subsequently, a well-shaped octahedral LuVO4 sample was synthesized at the expense of the wirelike precursor…
A highly sensitive and robust method for the determination of six gadolinium species by reversed-phase liquid chromatography coupled with inductively coupled plasma optical emission spectrometry (HPLC-ICP-OES) has been developed. The gadolinium(III) complexes, Gd–DTPA2−, Gd–DOTA1−, Gd–HP–DO3A, Gd–DTPA–BMA and Gd–DTPA–…
Enhancement of Luminescence Properties by Sr2 + Substituting Ba2 + in Red-Emitting Phosphors: Ba1 − y Sr y La2 − x ZnO5 : xEu ( x = 0 – 1 , y = 0 – 0.7 ) , Liang, Chih-Hao, Chang, Yee-Cheng, Chang, Yee-Shin
Purpose: Diamond nanoparticles are gaining much interest in biomedical applications due to the attractive chemical and biological properties. Studies have shown the potential of these “nanodiamonds” (NDs) for bioimaging, drug delivery, and biosensing. However, depending on the origin, the nanodiamond surface is often…
The sulfated glycosaminoglycans (sGAG) heparin and chondroitin sulfate (CS) were immobilized on the surfaces of gold nanorods as part of a polyelectrolyte multilayer. The effects of these nanomaterials on the self-assembly of type I collagen were examined by turbidity assays and microscopy, and desorption of sGAG from…
Nanoparticles can be dispersed by different methods in order to completely utilize their unique material characteristics. This study uses a self-developed nanofluid synthesis system to produce a CuO nanofluid with good suspension stability and particle dispersion without additives. The prepared CuO nanofluid has an av…
Two efficient pH-responsive oral delivery systems have been fabricated through a dative bonding between the amino-functionalized mesoporous silica materials, including MCM-41-type mesoporous silica nanospheres (MMSNs) and bimodal mesoporous silica microspheres (BMSMs), and an antitumour-active polyoxometalate K(8)H(2)…
We explore the dependence of the non-universal mesoscale structure of diffusion-limited aggregates upon the shape of their constituent particles. Using random-walker simulations that model anisotropic diffusion in a viscous fluid, we study diffusion-limited aggregation (DLA) of right-circular cylinders having a wide r…
In this paper, flowerlike Co11(HPO3)8(OH)6 superstructures were selectively synthesized via a facile hydrothermal route on a large scale in the presence of a certain amount of Ni2+ ions, employing CoCl2·6H2O and NaH2PO2·H2O as the reactants, NaHCO3 as the pH adjustor. HPO3− ions were provided based on the dismutation…
Citrate-functionalized titania nanocrystallites are successfully synthesized from a heteroleptic titanium alkoxide precursor in a low temperature, hydrolytic process and used as gold catalyst supports for CO oxidation and aerobic stilbene epoxidation.
N-type tellurium doped ZnSb was prepared by direct melting at 923 K after which it was quenched in water within an evacuated quartz ampoule. All the ingots were heat treated at 723 K for 100 h. The resultant samples were characterized by X-ray diffraction (XRD), differential thermal analysis (DTA) and by measurement o…
An unprecedented organo-ruthenium grafted asymmetric zinc-substituted sandwich-type tungstoarsenate, [{B-α-AsW9O34}{B-β-AsW8O31}{Zn4(OH)2(H2O)2}{(RuC6H6)3}]6− (1) has been synthesized and characterized, representing the fundamentally novel binding mode of Ru-coordination to a polyoxoanion fragment via Ru–O–W, Ru–O–Zn…
