Origin of O1sCore-Level Shifts on Oxygen AdsorbedSi(111)−(7×7)

Origin of metallic surface core-level shifts.

Surface Core - Level Shifts at an oxygen - rich Ru Surface :

We present density-functional theory calculations of Ru 3d and O 1s surface core-level shifts (SCLSs) at an oxygen-rich Ru(0001) surface, namely for the O(1× 1)/Ru(0001) chemisorption phase and for two surface terminations of fully oxidized RuO2(110). Including final-state effects, the computed SCLSs can be employed for the analysis of experimental X-ray photoelectron spectroscopy (XPS) data en...

the impact of attending efl classes on the level of depression of iranian female learners and their attributional complexity

می توان گفت واقعیت چند لایه ا ی کلاس های زبان انگلیسی بسیار حائز اهمیت است، زیرا عواطف و بینش های زبان آموزان تحت تاثیر قرار می گیرد. در پژوهش پیش رو، گفته می شود که دبیران با در پیش گرفتن رویکرد فرا-انسانگرایی ، قادرند در زندگی دانش آموزانشان نقش مهمی را ایفا سازند. بر اساس گفته ی ویلیامز و بردن (2000)، برای کرل راجرز، یکی از بنیان گذاران رویکرد انسانگرایی ، یادگیری بر مبنای تجربه، نوعی از یاد...

Non-local Effects on Oxygen-Induced Surface Core Level Shifts of Re(0001)

The electronic structure of clean and oxygencovered Re(0001) was investigated by combining high energy resolution core level photoelectron spectroscopy and density functional theory. For the clean surface, we detect two distinct Re 4f7/2 components shifted by 95 meV, which we ascribe to photoemission from the bulk and the top layer of the crystal. Oxygen adsorption at room temperature leads to ...

the effect of authentic listening materials on the listening proficiency of efl learners in the intermediate level

having conducted the experiment and analysed the data, the researcher computed the groups mean scores and variances for the test relating to the research question. as the final atep, a t-test was conodonted for the hypothesis. as noted earlier, the significance level was determined at .05 and .01 respectively. the observed t-value was higher than the critical t-value at. 5 and .01 levels. conse...
