This paper reports on a mixing system for microfluidic applications based on the acoustic streaming phenomenon. The system is based on an optimized piezoelectric transducer comprising a 25 μm thick poly(vinylidene fluoridetrifluoroethylene), P(VDF-TrFE), copolymer film with 85 nm thick electrodes of aluminium-doped zinc oxide (AZO). The system was tested for potential clinical applications allo...

Measurements of adsorption isotherms of a series of thirteen mono- and di-phosphonic acids have shown that these bind strongly to the surface of high surface area aluminium trihydroxide. The incorporation of such phosphonates into a suspension of aluminium flake in an aqueous medium, modelling the continuous phase of a water-based paint, greatly suppresses the evolution of hydrogen. Whilst stro...

We studied the correlation between the molecular structure and the formation of helical nanofilaments (HNFs) of bent-core dimeric molecules with varying linkage lengths. To obtain precise structural data, a single domain of HNFs was prepared under physical confinement using porous 1D nanochannels, made up of anodic aluminium oxide films. Electron microscopy and grazing incidence X-ray diffracti...

This paper proposes a novel approach to fabricate hyper-branched anodic aluminium oxide (AAO) nanostructures with different branches on the vertically-aligned trunk and at the trunk terminal. Silver nanowires with different dimensional and multifunctional complexity have been prepared from this hyper-branched AAO template by varying the electrodeposition time. These kinds of novel nanostructure...

The present article describes a new product for long-term retention of the lower dental arch. The LingLock is a fixed bonded retainer from canine to canine in the lower front made up of separate, but co-working retention elements in the ceramic material aluminium oxide (Al2O3). The LingLock retainer enables the patient to floss the teeth in a regular manner in the actual retention area.

Compounds containing the -PO3H2 function, such as monoesters of phosphoric acid and phosphonic acids, specifically bind to aluminium oxide in aqueous solution under experimental conditions where non-phosphorylated compounds are completely desorbed. The bound organic phosphate can be specifically displaced by aqueous solution of inorganic phosphates thus allowing their separation or detection by...

The development of nitric oxide (NO) releasing materials has been of significant importance due to their application in cell biology and biomedicine. Besides the macromolecular scaffold dangling NO releasing moiety, porous materials have been used to host such NO releasing molecules. Here we synthesized a series of porous coordination polymers (PCPs), in which N-nitrosamine functional groups as...

In this paper studies on Si/ZnO heterojunction diode is presented. In this work Zinc oxide (ZnO) was conformally deposited on Silicon (Si) Wafer by atomic layer deposition (ALD) technique without using a buffer layer. For low-temperature ALD deposition, diethyl zinc (DEZn) and deionized (DI) water were used as the sources for zinc and oxygen respectively. Surface characterization and optical ch...

The oxidation of both low and high-activity simple and Pt-modified aluminide coatings on nickel base superalloy IN738 has been studied in static air at 1100 OC up to 1000 h. For all coatings oxidation followed a parabolic law up to 400 h. The two Pt-modified coatings showed better protectiveness with lower mass gains and smaller rate constants, especially for long reaction times. The presence o...
