The number change of absorption peaks of three-layered nanoshells have been investigated in theory with variation of the composition. With an increase of the gold content in the inner core and outer shell, the number of absorption peaks changed from three to two and from one to two, respectively. And the corresponding physical mechanism had been discussed. The number tunability of peaks coming from the composition was affected by the geometrical parameters and the dielectric constant. This composition dependent number change of peaks would provide insights to synthesis and designing of three-layered nanoshells sensors for multi-molecular sensing..

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.
