Evaluation of bonding between oxygen plasma treated polydimethyl siloxane and passivated silicon

Evaluation of bonding between oxygen plasma treated polydimethyl siloxane and passivated silicon

Oxygen plasma treatment has been used extensively to bond polydimethyl siloxane to polydimethyl siloxane or glass in the rapid prototyping of microfluidic devices. This study aimed to improve the bonding quality of polydimethyl siloxane to passivated silicon using oxygen plasma treatment, and also to evaluate the bonding quality. Four types of passivated silicon were used: phosphosilicate glass...

examining the relationship between fear of negative evaluation and communication strategies by iranian efl learners

the purpose of the present study was to investigate the relationship between fear of negative evaluation (fne) and communication strategies (css) among iranian efl learners. it was aimed to examine the differences in the use of communication strategies between speakers with high or low degree of fear of negative evaluation. the current study was a case study consisting of 10 english learners at...

Stabilized electronic state and its luminescence at the surface of oxygen-passivated porous silicon

Photoluminescence ~PL! spectra of as-made porous Si samples were obtained in a wide peak-wavelength range. After exposure to air or coupling with C60 molecules, the PL peak shifts to a pinning wavelength within the range of 610–630 nm. This pinning wavelength is almost independent of the size of the original porous Si nanocrystallites and both redshifting and blueshifting can occur for differen...
