In this work, we present a new conceptual design in which two nozzles facilitate dual electrospray coexisting with ionic wind at chamfered tips by a direct current power source. Experimental results by a prototype have demonstrated the capability of simultaneously generating-and-delivering a stream of charged reduced particles. The concept can be beneficial to pulmonary nano-medicine delivery since the mist of nanoparticles is migrated without any restriction of either the collector or the assistance of external flow, but is pretty simple in designing and manufacturing devices.Thanh Van Dauv.dau@griffith.edu.auThanh Tung Buitungbt@vnu.edu.vnCanh-Dung TranCanh-Dung.Tran@usq.edu.auThanh Viet Nguyenthanh.nguyenviet@griffithuni.edu.auTuan-Khoa Nguyenkhoa.nguyentuan@griffithuni.edu.auToan Dinhtoan.dinh@griffithuni.edu.auHoang-Phuong Phanphuong.phanhoang@griffithuni.edu.auDavid WibowoDavid.Wibowo@griffithuni.edu.auBernd H.

Aligning with this approach, a new structure of valveless micro-pump is developed in this work. The mechanism of the present micro-pump is based on the combination of the nozzle and a tesla element to rectify the synthetic jet. The new structure of “ace of spades” nozzle, named Tesla coupled nozzle, creates series of vortexes at the orifice of the pump chamber that allows to attenuate the reversed flows while fluid is drawn through the pump. The present
micro-pump is simple but robust and can perform at rather low voltages.Canh-Dung TranCanh-Dung.Tran@usq.edu.auHong Phuc Phamphucph-fme@mail.hut.edu.vnTuan-Khoa Nguyenkhoa.nguyentuan@griffithuni.edu.auHoang-Phuong Phanphuong.phanhoang@griffithuni.edu.auToan Dinhtoan.dinh@griffithuni.edu.auThanh Viet Nguyenthanh.nguyenviet@griffithuni.edu.auThanh Tung Buitungbt@vnu.edu.vnDuc Trinh Chutrinhcd@vnu.edu.vnNam-Trung Nguyennam-trung.nguyenEmailgriffith.edu.auDzung Viet Daod.dao@griffith.edu.auThanh Van Dauv.dau@griffith.edu.au
