Active screen plasma nitriding enhances cell attachment to polymer surfaces
Active Screen Plasma Nitriding (ASPN) is a well-established technique used for the surface modification of materials, the result of which is often a product with enhanced functional performance. Here we report the modification of the chemical and mechanical properties of ultra-high molecular weight poly(ethylene) (UHMWPE) using 80:20 (v/v) N2/H2 ASPN, followed by growth of 3T3 fibroblasts on th...
متن کاملthe effects of nitriding parameters in hot working steel aisi h13 on its surface properties and nitride layers during conventional and active screen plasma nitriding treatments
the main aim of this research was to investigate the effects of plasma nitriding parameters including frequency and duty cycle for a seris of test samples with different grooves during conventional plasma nitriding (cpn) and active screen plasma nitriding (aspn) treatments. the sample assemblies were consisted of rectangular grooved steel blocks with different groove dimensions of 2, 4, 6, 8 an...

15 صفحه اولthe effect of lexical and grammatical collocation instruction through input flooding versus awareness raising on short-term and delayed retention as well a active use
this study attempted to explore if teaching english collocations through two different modes of awareness-raising and input flooding has any possible differential effect on immediate retention as well as retention in a delayed assessment. it also compared the possible differential effect of teaching english collocations implicitly and explicitly on actively using the items in writing. m...
15 صفحه اولthe effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
