A material specific peptide bound to Fe2O3 facilitates the selective sequestration of Au from a colloidal mixture of Au and CdS nanoparticles; the Au-Fe2O3 precipitate can then be magnetically separated from the colloidal CdS, and the Au nanoparticles can be recovered upon release from the Fe2O3.
Cordierite ceramics were prepared from several types of kaolin powders and talc powders having various median particle size with nanometer-sized alumina sol. Powder mixtures were uniaxially pressed, followed by cold isostatic pressing to make thin compacts. Crystal orientation of talc particle and resultant cordierite…
Various fabric properties are important for different sports applications. In order to improve fabric performance the focus is more on the material features of fabrics rather than the pattern. Fabric properties like moisture management, air permeability, and stretchability depend not only on the materials (the polymer…
The influence of the shape and grade of inserts upon the geometric structure of the composite coatings Ni-5%Al15%Al2O3 and alloy coatings of Ni-5% Al is considered in the paper. Nickel matrix coatings were sprayed by the Casto-Dyn 8000 torch on a steel substrate, and then subjected to straight turning. Determining of…
A Monte Carlo (MC) method is proposed by establishing a new model of phonon scattering processes with random sampling according to a scattering probability function. The MC scheme is used to simulate steady and transient ballistic-diffusive heat conduction in silicon nanofilm. In the MC simulations, we trace the phono…
Strong interaction between bubble and free-surface will cause complex phenomena, producing many different types of spike. Based on potential flow theory, a numerical model was established to simulate the crown spike. A downward jet was formed during the bubble’s collapsing, and simulation of the free-surface was conti…
Some modified styrene butadiene rubbers with functional groups at polymer chain ends have been prepared by solution polymerization system (S-SBRs). They showed reduction in the hysteresis loss of rubber compounds with silica or carbon black as reinforcing filler. Especially, the modified S-SBR with both primary amino…
2-layer aluminum/polyurethane (Al/PU) laminated sheets were prepared by a new adhesion method, a double-step treatment consisting of: (1) applying low dose ≦ 0.43 MGy homogeneous low energy electron beam irradiation (HLEBI) to the 2-layer assembly where the HLEBI penetrates through the Al and PU layers, respectively,…
With an objective to develop simple organic systems for optoelectronic applications, we have investigated photophysical properties of water soluble cyclophane derivatives 1, 2 and model compound 3 in solution and solid state. Of these, the symmetrical cyclophane 1 exhibited monomer emission in methanol, whereas an int…
Fluorine interaction assisted AIEE characteristic in an expanded calixbenzophyrin is presented by single-crystal X-ray-diffraction analysis and molecular modelling approaches. Selective exposure to volatile organic compounds such as ketones and esters results in the breaking of fluorine interaction, leading to enhance…
Magnetic and fluorescent bifunctional nanocomposites have great potential in biomolecule detection and biological imaging applications. So far, it remains a challenge to prepare bifunctional nanocomposites with high colloidal and fluorescent stability. To address this problem, we utilized a simple ring-opening reactio…

Copper silicate hydrates have been prepared by sol-gel method using stock solutions with different Cu/Si molar ratios. The synthetic gels were characterized by means of ICP-AES, TG-DTA, XRD, and EXAFS. Copper silicate hydrate gel having the chrysocolla-like structure was successfully formed in the gel samples prepared…
In this work, the optical properties of carbon–nickel films deposited at different deposition times from 50 to 600 sec were investigated. Reflectance measurements in wavelength range 300–1000 nm were used to compute the refractive index and optical dispersion parameters according to Wemple and DiDomenico single oscill…
The phosphogypsum (PG) sample produced as the waste of the phosphoric acid fertilizer plant from Guizhou, China was studied for its properties and as a material for anhydrite cement. The impurity content, type and distribution, as well as thermal behavior and solubility of the PG were carefully studied by XRD, DTA tec…
The mechanisms governing the sulfur poisoning of the triple phase boundary (TPB) of Ni-XSZ (X2O3 stabilized zirconia) anodes have been investigated using density functional theory. The calculated sulfur adsorption energies reveal a clear correlation between the size of the cation dopant X(3+) and the sulfur tolerance…
CeO 2 and Co containing CeO 2 thin films were deposited on indium tin oxide and stainless steel by anodic electrodeposition. Scanning electron microscopy showed that the films are flat and show globular morphology and cracks resulting from volume shrinking. According to XRD and Raman Spectroscopy pure ceria layers are…
In the paper, the analyses of Fe2p 3/2 and chromium Cr2p 3/2 XPS spectra with fitting by symmetrical and asymmetrical line shapes as well as using Linear, Shirley and Tougaard Method of Background Subtraction are presented. The calculations are performed on AISI 316L SS biomaterial after magnetoelectropolishing MEP op…
We report (i) synthesis of novel graft copolymers of a α-CD/PEG polyrotaxane (PRX) backbone and enantiomeric PLA side chains, PRX-g-PLLA and PRX-g-PDLA, (ii) selective stereocomplex formation on a movable PRX in the bulk state, and (iii) preparation of soft materials with continuous anisotropic phases by blending of t…
Pyrene-conjugated-hyaluronan (Py–HA) stabilises reduced graphene oxide (Py–HA–RGO) in water, with the composite material providing a substrate for building up nanostructures of Au, Ag, Pd and Pt, of varying sizes, shape, and surface properties. Formation of the metal is effective using in situ UV irradiation (Au and A…
