Effect of annealing on poly(urethane-siloxane) copolymers

Siloxane Copolymers for Nanoimprint Lithography**

Nanoimprint lithography (NIL) is a fabrication technology that offers high-throughput, ultrahigh resolution patterning at great cost savings compared to most competing next-generation radiative lithography methods. As a result of its rapid development in the past decade and its potential for sub-100 nm lithography, NIL has been listed by MIT’s Technology Review as one of ten emerging technologi...

effect of oral presentation on development of l2 learners grammar

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...

Effect of Siloxane Segment Length on the Surface Composition of Polyimidesiloxane Copolymers and its Role in Adhesion by

A series of polyimidesiloxane (SIM) copolymers, based on a.co-aminopropylpoly(dimethylsiloxane)(PDMS),2,2-bis(4-[4-aminophenoxyl]phenyl)propane(BAPP)and 4,4'-oxydiphthalic-anhydride(ODPA) was synthesized in our laboratories. We investigated the effect of siloxane segment length on the surface composition of the SIM copolymers and its role in adhesion. The aim is to elucidate the correlation bet...
