Development of alternative binder for lithium ion battery based on epoxy resin

Bunzel F., Wagner M., Stammen E., Dilger K., Technische Universität Braunschweig, DE

The development of batteries for the e-mobility continuously creates new challenges for the researchers. To improve performance of lithium ion batteries, different approaches might be considered. Therefore the Institute of Joining and Welding (ifs) focuses [...]

Mechanical Characteriztion of XD-Grade Carbon Nanotube/Epon 862 Processed by Dual Phase Dispersion Technique

Hossain M.K., Okoro C., Hosur M., Jeelani S., Rangari V., Tuskegee University, US

In this research, a dual-phase dispersion method is studied combining a high intensity ultrasonic liquid processor with a three roll milling technique. Xd-grade carbon nanotubes (xd-CNTs) were infused into Epon 862 epoxy and then mixed [...]

Fabrication and Thermomechanical Characterization of CNF-Filled Polyester and E-Glass/Polyester Nanophased Composites

Hossain M.E., Hossain M.K., Hossain M.E., Hossain M.K., Hosur M., Jeelani S., Rangari V., Tuskegee University, US

A high intensity ultrasonic liquid processor was used to infuse CNFs into the polyester matrix which was then mixed with catalyst using a high speed mechanical agitator. Results showed the significant improvement of mechanical properties [...]

An Evaluation of a Scanning Mobility Particle Sizer with NIST-Traceable Particle Size Standards

Vasiliou J., Duke Scientific Corporation, US

A scanning mobility particle sizer (TSI Model 3936) was evaluated using Duke Scientific NIST traceable particle size standards as well as NIST SRM’s. The importance of instrument setup, electrospray operation and sample preparation for polystyrene [...]
