The functionalization of multiwalled carbon nanotubes (MWNTs) with β cyclodextrin (β-CD) is described. The functionalization using β-CD treatment is an environmentally friendly and nondestructive method to modify carbon nanotubes. It was observed that the degree of functionalization increases with increasing ratios of β-CD as seen from the Raman analysis. The Raman spectra also indicated that the nanotubes walls were not damaged. The presence of functional groups associated with β-CD on the functionalized MWNTs indicated that the cyclodextrin groups were found to be adsorbed at the surface of the nanotubes walls. Mixed matrix membrane (MMM) was prepared by a phase inversion process. Enhanced selectivity and permeability for CO2 over CH4 was observed for MMM prepared using functionalized MWNTs.

Purpose: This study was designed to develop an evaluation tool for assessing professional behavior and clinical competencies from the graduates’ perspective. Methods: This study employed mixed method in a sequential exploratory design. The semi-structured interviews were conducted with three graduates from different cohorts. The qualitative analysis of the interviews found six emerging themes for professional behavior and clinical competencies development. These themes were then developed into a 55-item questionnaire. The questionnaire was then distributed to 84 medical graduates for exploratory factor analysis (EFA) from February to April 2019. The quantitative data were analyzed using IBM SPSS ver. 21.0 (IBM Corp., Armonk, USA) for principal axis factoring. After conducting EFA, we proceeded with confirmatory factor analysis (CFA) with another 120 graduates to validate the tool. Results: Eighty-four graduates completed the questionnaire for EFA. Upon completion of EFA, 35 out of 55 items of the questionnaire were found to be valid and reliable. The most appropriate fit was seven factors, which explained 58.18% of variance between them after 15 iterations with Cronbach’s α of 0.916. The personal satisfaction factor was noted to be weak. It was therefore added to patient management factor due to its similar intention. The final EFA factor after the modification was six. The CFA found that 34 out of 35 items was valid and reliable that representation of the latent variables. Conclusion: The questionnaire has achieved the desired construct validity score and can be used as an evaluation tool to assess professional behavior and clinical competencies from the graduates’ perspective.

A REVIEW OF PURIFICATION TECHNIQUES FOR CARBON NANOTUBES
A. F. ISMAIL,PEI SEAN GOH,JIA CHEE TEE,SUHAILA M. SANIP,MADZLAN AZIZ 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2008 NANO Vol.3 No.3
Purification of carbon nanotubes (CNTs) is a very actively discussed topic in contemporary CNT literature. To a large extent, impurities embedded in CNTs influence the physical and chemical characteristics of the CNTs. Different purification methods yield different CNT characteristics and may be suitable for the production of different types of CNTs. Developments in the purification methods of CNTs are reviewed and the production methods are briefly discussed and summarized. This is followed by a detailed description of the three major purification methods, viz. chemical, physical and multi-step purification.
