چکیده
Metal coordination assemblies of the symmetric bi-functional 4,4'-di-(1,4-buta-1,3-diynyl)-benzoic acid are investigated by scanning tunnelling microscopy on metal surfaces. The formation of long-range ordered, short-range disordered and random phases depends on the competition between the convergent and divergent coordination motifs of the individual functional groups and is crucially influenced by the substrate.

The Impact of Divergent and Convergent Tasks on Iranian EFL Students’ Reading Comprehension Success
This study was an attempt to investigate the effect of divergent and convergent tasks on intermediate EFL students' reading comprehension success. The participants of this study involved sixty male and female EFL learners who were enrolled in the intermediate level at Kish English Institute in Yasuj. To make them homogeneous in terms of their general English knowledge, they were asked to take p...
متن کاملSteady Flow Through Modeled Glottal Constriction
The airflow in the modeled glottal constriction was simulated by the solutions of the Navier-Stokes equations for laminar flow, and the corresponding Reynolds equations for turbulent flow in generalized, nonorthogonal coordinates using a numerical method. A two-dimensional model of laryngeal flow is considered and aerodynamic properties are calculated for both laminar and turbulent steady flows...

One-dimensional (1D) coordination polymer, [Zn(4,4´-bpy)(H2O)4](ADC).4H2O (1) (4,4´-bpy = 4,4´-bipyridine and H2ADC = acetylenedicarboxylic acid), and three-dimensional (3D) metal-organic framework (MOF), Zn(ADC)2.(HTEA)2(2) (HTEA = triethylamine) were prepared at room temperature. The compounds were characterized by single-crystal X-ray diffraction and powder X-ray diffraction (PXRD) analyses....
متن کاملBiophysical Constraints Arising from Compositional Context in Synthetic Gene Networks.
Synthetic gene expression is highly sensitive to intragenic compositional context (promoter structure, spacing regions between promoter and coding sequences, and ribosome binding sites). However, much less is known about the effects of intergenic compositional context (spatial arrangement and orientation of entire genes on DNA) on expression levels in synthetic gene networks. We compare express...
