Abstract

This paper is to investigate the effect of google usage on uumsqs final yearstudents’ academic performance. The scope of this paper is focusing on studying the effects of google usage on university utaramalaysia (uum) students’ academic performance. This study has been carried out among final year students of school of quantitative science (sqs) by did survey through asking respondents for information using written questioning which is questionnaire. The survey from the respondents takes time almost a week. It is believe that google usage will create a positive impact on students. By doing this study, students can know whether google is affecting their academic performance. The sources where students refer for academic purpose can also been seen. Besides, the role of google that can help students to gain extra knowledge in the learning process can be identify. Students can find out more advantages that is brought by google which can leave a positive effect on their academic performance.

Abstract

This study introduces multi-walled carbon nanotubes (MWCNT)/chitosan (CS) composite as a potential new sensing material for quartz crystal microbalance (QCM) formaldehyde sensors. This sensing material selectively binds target molecules, causing a measurable frequency shift proportional to the added mass. CS, MWCNT, and the MWCNT/Cs composite samples were prepared for comparison via sonification, crosslinking and dispersion methods. The morphology character was studied using Raman spectroscopy, Fourier transform infrared (FTIR) spectroscopy, and field emission scanning electron microscopy (FE-SEM). Next the samples were drop cast on the QCM working electrode. An adsorption test was conducted to study the static and dynamic response for the formaldehyde detection. The frequency shift of the formaldehyde adsorption for the CS, MWCNT-COOH, and MWCNT/CS-based sensors were 114.98 Hz, 108.23 Hz, and 196.63 Hz respectively. The calculated sensitivity of 23.48 Hz/ppm and regression line R2 at 0.95076 were recorded shows that the MWCNT/CS can be a promising sensing layer to detect formaldehyde vapour.
