The Eff ects of Chemical Element Symbols in Identifying 2D Chemical Structural Formulas

چکیده
is study aims to explore the eff ect of chemical element symbols in students’ identifi cation of 2D chemical structural formulas. A chemical conceptual questionnaire, event-related potential experiments and interviews were administered to fi y university students in this study. e results revealed that high achieving students perfprmed diff erent brain activities and strategies to identify 2D fi gures (without chemical elements symbols inside) and 2D chemical structural formulas. However, low achieving students ignored the existence of chemical element symbols and performed similar brain activities and strategies when identifying 2D fi gures and chemical structural formulas. is paper discusses implications for new education.

TOPOLOGY OPTIMIZATION OF 2D BUILDING FRAMES UNDER ARTIFICIAL EARTHQUAKE GROUND MOTIONS USING POLYGONAL FINITE ELEMENT METHOD
In this article, topology optimization of two-dimensional (2D) building frames subjected to seismic loading is performed using the polygonal finite element method. Artificial ground motion accelerograms compatible with the design response spectrum of ASCE 7-16 are generated for the response history dynamic analysis needed in the optimization. The mean compliance of structure is minimized as a t...

Hyphenating High Temperature High Performance Liquid Chromatography (HT-HPLC) with High Temperature Size Exclusion Chromatography (HT-SEC) (High Temperature Two Dimensional Liquid Chromatography (HT-HPLC x HT-SEC or HT 2D-LC)) leads to an isocratic elution in the second dimension, which in turn enables to use IR detector (quantitative detection) for monitoring the eluting polymers. Experimental...

This paper introduces a computational strategy to collaboratively develop the Galerkin Finite Volume Method (GFVM) as one of the most straightforward and efficient explicit numerical methods to solve structural problems encountering material nonlinearity in a small limited area, while the remainder of the domain represents a linear elastic behavior. In this regard, the Element Free Galerkin met...
متن کاملAb Initio Calculation 29Si NMR Chemical Shift Studies on Silicate Species in Aqueous and Gas Phase
Nowadays NMR spectroscopy becomes a powerful tool in chemistry because of the NMR chemical shifts. Hartree–Fock theory and the Gauge-including atomic orbital (GIAO) methods are used in the calculation of 29Si NMR chemical shifts of various silicate species in the silicate solution as initial components for zeolite synthesis both in gas and solution phase. Calculations have been performed at geo...
متن کاملWith the same Clar formulas, do the two-dimensional sandwich nanostructures X-Cr-X (X = C4H, NC3 and BC3) behave similarly?
The "perturbation" effects (i.e. hyperconjugation, electronegativity, and conjugation) on the structural, electronic, and magnetic properties of three kinds of two-dimensional (2D) X-Cr-X (X = C4H, NC3 and BC3 monolayers) sandwich nanostructures were systematically investigated by means of spin-polarized density functional theory (DFT) computations. Although all these 2D sandwich systems energe...
