Dr. Shin-ichi Yusa belonging to Department of Applied Chemistry, University Hyogo has invited me. We have already collaborated for many years. The purpose to visit Japan is to develop the collaboration.
During the period, the researchers have been able to obtain the following tasks
1. We have synthesized and characterized four new surfactants. The critical micelles concentration of these surfactants were also quantified by conductivity. The chemicals will be tested by tensiometry in Perth, Australia in coming months. It is expected that data and two scientific papers will be submitted by the end of 2018.
2. We also quantify the CMC and micellar behaviour of alkyl trimethylammonium bromide surfactants. A series of surfactant with linear increased length were employed. The results show interesting correlation which has not been reported in the literature. The data with theoretical interpretation will be used to prepare another manuscript in the coming weeks.
Expected outcomes: we expect three significant manuscripts will be submitted to the reputable journals in surface and colloid chemistry (Langmuir, Colloids and Surfaces) by the end of 2018.
Teaching
During the stay, the visitor has delivered three lectures:
- 26 Dec 2017 in Harima campus, titled “How water can float on oil”
- 5 Jan 2018, Mt. Shosha campus, titled “Dynamic adsorption of surfactant at interfaces”
- 15 Jan 2018, Mt. Shosha campus, titled “surface and colloids chemistry in chemical engineering”
Summary
During the short stay, the visitor has been able to achieve great outcomes in the both research and teaching. This was only possible via the great and enthusiastic support from the host and other academic staff. The results will further strengthen the collaboration. The visitor sincerely thanks the HORN program for this opportunity.
