Method for production of tooling for microstructure surfaces

Synthesis of conductive elastic film and conductive fabric based on crosslinked carboxymethyl starch-AgNPs composite

El-Sheikh M.A., National Research Centre, Egypt, EG

The current work is developing a novel, facile and eco-friendly method for synthesis of highly concentrated silver nanoparticles (AgNPs) using AgNO3 as a precursor, the eco-friendly carboxymethyl starch (CMS) polymer as both reducing and stabilizing [...]

Intense Pulsed Light Sintering and Reduction of Facile Copper Hydroxide Synthesis towards Printable Copper Contacts

Druffel T., Dharmadasa R., Draper G., University of Louisville, US

The printed electronics market is a rapidly growing field, with the market set to reach $3.6B by 2018. Conductive inks are used in a vast variety of technologies. Inks are typically composed of metallic particles [...]

A family of MAV drives investigation

Dalewski R.T., Gumowski K., Barczak T., Godek J., Warsaw University of Technology (Politechnika Warszawska), PL

A critical overview of a family of drives designed for MAV purposes was conducted. In the family of drives ducted and non-ducted solutions of two counter-rotating and single propeller systems were tested. Rotor diameter for [...]
