Unbalanced 2D Chiral Crystallization of Pentahelicene Propellers and Their Planarization into Nanographenes
نویسندگان
چکیده
The chiral self-assembly of trispentahelicene propellers on a gold surface has been investigated in ultrahigh vacuum by means scanning tunneling microscopy and time-of-flight secondary ion mass spectrometry. aggregate into mirror domains with an enantiomeric ratio 2 : 1. Thermally induced cyclodehydrogenation leads to planarization nanographenes, which self-assemble closed-packed layers two different azimuths. Further treatment induces part dimerization trimerization intermolecular cyclodehydrogenation.

15 صفحه اولan investigation into elt teachers’ sense of self-efficacy in teaching reading comprehension and their personality types
as far as bandura’s (1977) conceptualization of the sense of self-efficacy is concerned, it is argued to be context- and even task-specific, compared to other concepts like self-esteem (brown, 2000); therefore, upon the previous research studies, related theories and definitions, and the ideas and views obtained from the interviews conducted with the scholars, the current research study aimed a...
2D conglomerate crystallization of heptahelicene.
Two-dimensional (2D) nucleation and crystallization of the helical aromatic hydrocarbon heptahelicene on the single crystalline copper(100) surface has been studied with scanning tunnelling microscopy. In contrast to previously observed racemic 2D crystals on Cu(111), separation into homochiral domains is observed for Cu(100).
متن کاملFrom Homochiral Clusters to Racemate Crystals: Viable Nuclei in 2D Chiral Crystallization.
The quest for enantiopure compounds raises the question of which factors favor conglomerate crystallization over racemate crystallization. Studying nucleation and crystal growth at surfaces with submolecular-resolution scanning tunneling microscopy is a suitable approach to better understand intermolecular chiral recognition. Racemic heptahelicene on the Ag(100) surface shows a transition from ...

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...
