Various applications of nanostructures in electronics, optoelectronics, MEMS, photonics and plasmonic make their fabrication an interesting research topic recently. Progress in nanotechnology depends on the capability to fabricate, position and interconnect nanometer-scale structures. The development of fabrication devices with nanoscales is mainly dependent on the existence of a suitable nanolithography approach. Patterning materials with nanoscale features aimed at improving integration and device performance faced several challenges. The limitation of conventional lithography systems including resolution related issues, operational costs and lack of flexibility to pattern organic and... 

Molecular communication (MC), is a new way of communication among nanomachines.its applications are typically in cases which the conditions of transfer such as size, nature of the medium and nature or type of the original signal, is consistent with molecules such as medicine, health care, industrial and environmental applications.In this thesis, we first review different models of molecular transmitters. In most of them, storage capacity and molecule generation rate are not considered. we try to propose practical transmitter models considering these limitations. for high storage capacity transmitters, we propose Fixed and Linear transmission methods. assuming that channel is without...
