Nanoparticles by Design Unit (Mukhles Sowwan)

Nanotechnology is a revolution with endless possibilities. It has the potential of numerous applications in various technologies. However, one of the issues that has plagued the development of these technologies has been the inability to produce nanoparticles with tailored characteristics to be utilized to their full potential.

The Nanoparticles by Design Unit is composed of a multinational team of researchers from all over the world, with diverse scientific backgrounds, ranging from materials science through physics to chemistry and biology, under the supervision of Prof. Mukhles Sowwan. Our research focuses on the design of nanoparticles for particular applications such as  smart gas sensors, label-free biosensors, hydrogen storage, etc. We combine heterogeneous gas phase synthesis, mass filtration, and controlled deposition techniques to tune the size, shape, chemical composition, microstructure, and degree of crystallinity of the nanoparticles in order to optimize their chemical and physical properties for the development of nanoparticle-based advanced technologies.

Latest News & Highlights

01/05/2018 - Brand new! The NbD Unit is currently undergoing what feels like a phase transition, as not one, not two, but four new members have just joined us! First, Pawan Kumar and Abheek Datta arrived in Okinawa at the beginning of April, followed by Intu Sharma and Zhenwei Wang in May. All new postdoctoral researchers can bring fresh ideas to our research, as they have different background and expertise. We are looking forward to working with all of them, and are very excited about new research opportunities opening up. Welcome all, and good luck!

03-06/04/2018 - This week, the "Nanomaterials and Devices by Cluster Beam Deposition" symposium was held during the MRS Spring Meeting 2018 in Phoenix, AZ. The symposium was co-organized by Mukhles Sowwan, the director of the NbD Unit, and was attended by most unit members, who contributed oral or poster presententations. Eric Danielson's talk was on "Metal oxide nanowire bio-sensors decorated with gold nanoparticles via cluster beam deposition", followed by Zaki Ziadi's presentation of "Size-selected Pd nanoparticle coverage effect on CuO nanowire-based gas sensors". These two talks, along with Alex Porkovich's poster on "Applications of nanowire supported catalytic nanoclusters in gas sensing" covered our recent work on nanoparticle-based sensors, while, continuing with our applied research, Marta Haro spoke about her recent results on "Design of nanoparticle scaffolds to customize Li-ion batteries". Panos Grammatikopoulos' talk, however, on "Stable vs. metastable configurations of miscible and immiscible bimetallic nanoparticles grown by cluster beam deposition" and Evropi Toulkeridou's poster on "Meso-scale analytical model for nanoparticle coalescence" focused on more fundamental aspects of our research. Overall, the symposium was very successful, with high attendance throughout, and interesting presentations and productive discussions in a friendly environment.

28/03/2018 - Partying and Parting: Today we had a little farewell party for Panagiotis Koutsogiannis, our spring-term student intern, and Nan Jian, our TEM expert, who are both leaving the Unit at the end of the month. Panos jr is going back to his native Cyprus, but, following the tradition of our previous interns, has promised to return to Okinawa very soon. We all knew that Nan had a great future awaiting him when he joined us last year, but did not expect that the future would come so soon! Nan is returning to his homeland, China, where he will take the next, higher, step in his career. We wish them both good luck and will be happy to work with them again in ongoing and future projects!
