(I) CHROMATOGRAPHIC METHODS FOR SOLUTE DESCRIPTORDETERMINATIONS(II) RUTHENIUM SUBSTRATE-CATALYZED GROWTH OF NICKEL NITRIDETHIN FILMS BY ATOMIC LAYER DEPOSITION

Many stone-covered surfaces on Earth are subject to aeolian deposition of atmospheric dust. This study investigates how the deposition of dust is affected when rock fragments become gradually more embedded in the ground or, inversely, become more concentrated on the surface. Experiments were executed in an aeolian dust wind tunnel with eight different types of pebbles. The following parameters ...

Atmospheric nitrogen species including NO3-, NH4+ and total nitrogen in air and precipitation samples were collected with low-volume filter packs and wet deposition collectors from March 1999 through the end of December 2000 in seven sampling locations in Connecticut. Three sampling locations were chosen along the shores of Long Island Sound and four were chosen in interior sections of Connecti...

The specific objective of this paper is to develop a fully implicit compositional simulator for modeling asphaltene deposition during natural depletion. In this study, a mathematical model for asphaltene deposition modeling is presented followed by the solution approach using the fully implicit scheme. A thermodynamic model for asphaltene precipitation and the numerical methods for performing f...

Visceral urate deposition (visceral gout) is a common finding during post-mortem examination of poultry. Rare cases of visceral gout may occur in wild birds. A rare case of visceral urate deposition in a little bittern (Ixobrychus minutus) is reported here. In May 2013, carcass of a little bittern was submitted for necropsy to the Clinic of Poultry Diseases (Faculty of Veterinary Medic...

When prepared by conventional evaporation or sputtering, thin films of amorphous silicon contain a large concentration of defects and microvoids.3,4 These give rise to localized states in the energy gap of the material.3,4 Plasma-enhanced chemical vapor deposition (PECVD), using silicon hydrides, significantly reduces the number of defects and thereby lowers the concentration of localized state...

We report a simple sonochemical method for the seeding and synthesis of Zinc Oxide nanowire arrays that can be formed on a number of substrates that are stable in alcohol and aqueous solution. Vertically aligned ZnO NWs were synthesized from a single solution at room-ambient via ultrasonic excitation. Prior to the NW growth, a ZnO seed layer was deposited using the same system with a different ...

Titanium Nitride (TiN) coatings have led the way for providing increased wear resistance and extended life of cutting tools, whether carbide inserts or high-speed steel. Where the earliest applications were for high temperature substrate materials (carbides) and chemical vapor deposition (CVD) was the process of choice, later developments in the physical vapor deposition (PVD) technology, espec...
