Novel electrohydrodynamic atomization of metallo-organic silver ink in fully voltage-controlled form was investigated. During the spray, different atomization modes including pulsation and cone-jet were observed by a high-resolution CCD video microscope. By using an electrified-fluid-jet in either pulsed transient or steady mode, silver relics with ∼200 μm diameters were successfully deposited on a Si substrate. Distinction in the morphology of the relics was revealed by SEM, which can be attributed to the varying jetting throughput at different voltages, and particularly in different modes. EDX analysis confirmed the main composition in all the relics after heat treatment was silver. The results demonstrated that pulsation and cone-jet are both effective modes in electrohydrodynamic jet (e-jet) printing..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
