This work characterized the Cl2/HBr ion-enhanced plasma-surface interactions with poly-silicon as a function of the gas composition, ion energy, ion incident angle and other important process parameters. A realistic inductively coupled plasma beam apparatus capable of generating ions and neutrals representative of a real commercial etcher was constructed and utilized to simulate accurately a hi...

The composition of aerosol from cloud droplets differs from that below cloud. Its implications for the Cloud Condensation Nuclei (CCN) activity are the focus of this study. Water-soluble organic matter from below cloud, and cloud droplet residuals off the coast of Monterey, California were collected; offline chemical composition, CCN activity and surface tension measurements coupled with Köhler...

The aim of the present work was to assess the feasibility of Acconon MC8-2 EP/NF as a bioadhesive material for developing controlled release gastroretentive microsponges of loratadine. Modified emulsion-solvent diffusion method was employed for the preparation of microsponges (F1-F9) based on  32 factorial design. The amount of ethyl cellulose (EC) and polyvinyl alcohol (PVA) were selected...

It is known that surface structural relaxation takes place more rapidly than bulk structural relaxation, especially in the presence of water vapor. The surface structural relaxation kinetics of the silica glass fiber and plates was compared at 950 C and the surface structural relaxation kinetics of silica glass fiber was found to be faster than that of the silica glass plate, even though the co...

Microfluidic DNA biochips capable of detecting specific DNA sequences are useful in medical diagnostics, drug discovery, food safety monitoring and agriculture. They are used as miniaturized platforms for analysis of nucleic acids-based biomarkers. Binding kinetics between immobilized single stranded DNA on the surface and its complementary strand present in the sample are of interest. To achie...

A fractal analysis is used to model the binding and dissociation kinetics of connective tissue interstitial glucose, adipose tissue interstitial glucose, insulin, and other related analytes on biosensor surfaces. The analysis provides insights into diffusion-limited analyte-receptor reactions occurring on heterogeneous biosensor surfaces. Numerical values obtained for the binding and the dissoc...

This work presents a demonstrator for online monitoring of pesticides or water contaminants which is robust, fast, specific and low cost. The system is designed for continuous monitoring in water matrices (sourceand surface water, treated waste water), and is thus completed with an automated fluidics. The main characteristics of the system are: (a) Detection based on competitive immunoassay; (b...
