Bismuth molybdate (Bi2MoOe) was synthesised by utilizing Bi(NO3)3'5H2O and (NH4)eMo7O24'4H2O through hydrothermal method. Bi2MoOe loaded on polyethylene (PE) to prepare the film with photocatalytic properties. The product characterised XRD UV DRS spectra investigated degradation of sulfanilamide under solar light. results confirmed a efficiency 66%.

A bioactive polyethylene substrate can be produced by incorporation of sulfonic functional groups (-SO3H) on its surface and by soaking in a calcium hydroxide saturated solution. Variation of the surface potential of the polyethylene modified with -SO3H groups with soaking in a simulated body fluid (SBF) was investigated using a laser electrophoresis zeta-potential analyzer. To complement the s...

BACKGROUND A major cause of the limited longevity of total ankle replacements is premature polyethylene component wear, which can be induced by high joint contact pressures. We implemented a computational model to parametrically explore the hypothesis that intercomponent positioning deviating from the manufacturer's recommendations can result in pressure distributions that may predispose to wea...

A soft stylus microelectrode probe has been developed to carry out scanning electrochemical microscopy (SECM) of rough, tilted, and large substrates in contact mode. It is fabricated by first ablating a microchannel in a polyethylene terephthalate thin film and filling it with a conductive carbon ink. After curing the carbon track and lamination with a polymer film, the V-shaped stylus was cut ...

Conditions for the transfer printing of patterned carbon nanotube (CNT) films, along with a Au-gate, a poly methylmethacrylate (PMMA) dielectric layer and Au source-drain electrodes have been developed for the fabrication of thin-film transistors on a polyethylene terephthalate (PET) substrate. Chemical vapor deposition (CVD) grown CNTs were patterned using a photolithographic method. Transfer ...

Homogenous cesium tungsten tri-oxide (CsAW1O3) and powder was prepared by solvothermal reaction using (NH4)10H2(W2O7)6 and Cs2CO3 aqueous solution followed by annealing. The cesium doped tungsten tri-oxide (CsAW1O3) nanocomposite films was deposited by the sol-gel bar-coating method onto PET-film (polyethylene terephthalate film, thickness 186 μm) substrate. The structure and sizes of ceramic p...

We study the spreading of spheroidal aggregates of cells, expressing a tunable level of E-cadherin molecules, on glass substrates decorated with mixed fibronectin and polyethylene glycol. We observe the contact area by optical interferometry and the profile by side-view microscopy. We find a universal law of aggregate spreading at short times, which we interpret through an analogy with the spre...

Post-coating of biodegradable polylactides (PLA)/polyethylene glycol (PEG) microspheres with a gelatin film produced by dipping the microspheres into a gelatin solution to reduce the initial drug release burst was investigated. Biodegradable block PLA/PEG microspheres, prepared by w/o emulsion/solvent evaporation, showed that the hydrophilic segment PEG protruded to the sphere surface. However,...

The hydrophilicity ageing of polypropylene (PP) and polyethylene terephthalate (PET) films treated by nonthermal plasma usually takes over 150 days. In the present work, the accelerated ageing induced by hydrogen atoms and ultraviolet (UV) radiation with a wavelength of = 253.7 nm was studied. It was experimentally found that the hydrogen atoms restored the modified polymers to their original h...

One of the most efficient and versatile ways to synthesize polyolefin nanocomposites is the in-situ polymerization of olefins in the presence of nano particles by metallocene catalysts. Metallocene/methylaluminoxane (MAO) catalysts are soluble in hydrocarbons and therefore they can be absorbed perfectly in solution onto the surface of particles or fibers and after addition of ethene or propene ...
