Automotive catalysts can be exposed to various poisonous substances that cause physical or chemical deactivation. One of such poisons is phosphorous, which originates from lubricant oils. This study focuses on the phosphorus deactivation Pd/SSZ-13 used as a passive NOx adsorber (PNA). A clear caused by was observed, and it increased increasing content phosphorous. It concluded phosphorous both ...

Excessive use of animal manure as fertilizers can lead to pollution through the introduction nitrogen, phosphorus, and other mineral compounds environment. Wet chemical analytical methods are traditionally used determine precise composition manage application waste soil. However, such require significant resources carry out processes. Affordable, rapid, accurate analyses various components pres...

Submicron tantalum pentoxide ridge and channel optical waveguides and microring resonators are demonstrated on silicon substrates by selective oxidation of the refractory metal, tantalum. The novel method eliminates the surface roughness problem normally introduced during dry etching of waveguide sidewalls and also simplifies fabrication of directional couplers. It is shown that the measured pr...

In this seminar, I will present our recent work on the growth and electrochemical properties of single crystalline vanadium pentoxide (V2O5) nanorod and Ni-V2O5·nH2O nanocable arrays. These nanostructures were prepared by solution synthesis and template-based electrodeposition. Processing, morphology, structure and electrochemical properties of these nanostructures will be discussed. These nano...
