The sample consisted of 102 grade 10 students from three secondary schools in Chaiyaphum province in the northeast of Thailand. After studying this topic, the students responded to a 9-item two-tier multiple- choice test bonding (Tan & Treagust, 1999), translated into the Thai language which ...
Chemical Bonding and Reactions - Science - 10th Grade Presentation Free Google Slides theme, PowerPoint template, and Canva presentation template Did you know that everything around us, from the trees outside to the water we drink, is made up of different chemicals that bond together? Well,...
Ionic bonding can be best imagined as one big greedy dog steeling the other dog's bone. If the bone represents the electron that is up for grabs, then when the big dog gains an electron he becomes negatively charged and the little dog who lost the electron becomes positively charged. The...

X-ray photoelectron spectroscopy (XPS) gives important information on the chemical composition of a surface by analyzing peaks for different bonding energies [18]. Wei et al. [19] performed a plasma treatment with carbon tetrafluoride on poly(ether sulfone), and studied the induced changes by XPS...
This paper presents the influence of production parameters and analysis of ZrC coatings production on Monel®400 substrate. The effects of laser beam power on the microstructure, chemical composition, corrosion resistance and on selected mechanical pro
