Impact of MWCNTs on the structural, electrical, and optical characteristics of PVA/PANi blends

open access: yesJournal of Taibah University for Science, 2023
Polyvinyl alcohol (PVA)/0.25% polyaniline (PANi)/x wt % MWCNTs (x = 0, 0.1, 0.2, 0.5, 0.8, 1) blends were formed. The X-ray diffraction technique was used to investigate the formation of the different blends.

Public Perception of the Introduction of Autonomous Vehicles

open access: yesWorld Electric Vehicle Journal, 2023
Autonomous vehicles (AVs) will transform transport, but public opinion will play a key role in decisions on how widely and quickly they are adopted. The purpose of the study presented here was to investigate community’s views on that transition.

Electric Vehicle Communities for Electric Market [PDF]

open access: yesWorld Electric Vehicle Journal, 2010
In this work is proposed the design of a system to create and handle an Electric Vehicle (EV) community, based on social networks collaborative approach and a credit mechanism to incentive participation and divide profits. This system is part of a V2G (Vehicle-to-Grid) module that allows EV owners to be aggregated in communities and participate in the ...
