A system for vehicular misbehavior detection, comprising: a vehicular network, and a misbehavior authority in communication with vehicles in the vehicular network, the misbehavior authority configured to receive a misbehavior report from at least one of the vehicles in the vehicular network, the misbehavior report based on a determined discrepancy between a collective perception message (CPM) received from a malicious vehicle and sensor data of the at least one of the vehicles, receive sensor data from the vehicles in the vehicular network, generate an environment map based on the sensor data received from the vehicles in the vehicular network, analyze the misbehavior report by comparing information in the misbehavior report with the generated environment map, and initiate a certificate revocation process for the malicious vehicle if the misbehavior report is verified.

The present disclosure describes methods of producing superhydrophobic carbon nanotube sheets. The methods disclosed herein allow the rapid and scalable production of superhydrophobic carbon nanotube sheets that may remain on a substrate, or they may be removed from the substrate to produce freestanding superhydrophobic carbon nanotube sheets. The carbon nanotube sheets produced by the present methods were confirmed to be superhydrophobic by water droplet contact angle.
