​NEWRI-R3C Sharing Session​ (​NRSS) Season 3​

Published on: 03-May-2017

​Objective​

  1. To improve skills on public speaking, questions handling and preparation of presentation aids (contents/formats/illustrations) for all R3Cians.
  2. To update research progress, increase awareness of R3Cians as ambassadors representing NTU-NEWRI-R3C and promote bonding as a cohesive research group.​
  3. ​To promote interdisciplinary learning, discover opportunity in the interfaces between disciplines/projects and encourage cooperation in research proposals + TD/patents development.

​Title: Metal Organic Frameworks for the Fluorocarbon Capture and Separation

Introduction: 

Metal Organic Frameworks are the novel class of hybrid material, which are composed of metal oxides units attached together covalently by organic linkers to form architecturally stable structures with permeant porosity. So far, they have shown enormous potential applications in different technological fields including gas storage, separation, catalysis, sensing, drug delivery and etc. Striking increase of all type of MOF structures (1D, 2D, 3D) are reported during the past decade, mainly because of the designability and adjustability in their structures and functions as suitable for various types of applications.
 
In this presentation, suitability of  MOFs over other conventional porous adsorbents for the adsorption based fluorocarbon separations will be discussed under below considerations:​

- Higher adsorption capacity due to larger surface area and pore volume;
- Tunability of pore size for the shape-selective separation and possible pore surface functionalization for the selective gas adsorption;
- High stability;
- Several possible synthesis routes as suitable for industrial scale production;
- Moderate energy requirement for regeneration.​

 Title: Removal of Glyphosate Metal Complexes Using an Adsorbent

Introduction: 

Glyphosate (N-phosphonomethyl-glycine) (GPS) is a nonselective, broad-spectrum systemic herbicide. It, due to the zwitterionic behavior induces strong metal chelating abilities resulting in formation of metal complexes with heavy metals containing in soil and water. Previous studies have demonstrated the increased risk of kidney diseases by GPS-metal complex detected in surface waters. To overcome the health risks associated with the utilization of GPS in agriculture, the removal of herbicide from water is required. The scope of this study is to analyze the characteristics and speciation of GPS-Metal complexes and develop hierarchically structured porous carbon material to adsorb GPS-Metal complexes.
 
This presentation will cover:

- A brief Introduction to Glyphosate and Glyphosate metal complexation;
- Change in speciation with the presence of different compounds;
- Challenges and Future Directives.​​

 Title: The Change of Fate of Heavy Metals in Biochar Combustion over Sludge Direct Combustion

Introduction: 

Pyrolysis  of sewage sludge brings the stability for the heavy metals which were tend to leach out. This study was conducted to analyse the effect of this stability by introducing biochar into secondary combustion process.

 Title: Development of A Micro Total Analysis System (µTAS) for Environmental Pollutant Detection

Introduction: 

Du​e to the large amount of pollutant species and the frequent needs of test, it is highly desired that multiple pollutants can be detected in one-run within a short period of time, and the cost should also be as low as possible. Currently only a few techniques such as ICP-MS, ICP-OES, LC-MS, HPLC and GC-MS have the capabilities of identifying the multiple pollutants in one-run. However, they are delicate, bulky and expensive instruments that can be operated in laboratories only. To solve the above problems, we integrated the complicated functions of solid phase extraction (SPE), electrochemical (EC) detection and capillary electrophoresis - capacitively coupled contactless conductivity (CE-C4D) detection into a disposable micro total analysis system (µTAS), for rapid while sensitive on-site detection of multiple pollutants (e.g. tens of heavy metals and phenolic compound) in liquid sample within 30 minutes.
