Research
Based on aerosol nanotechnology, our group harnesses the “artificial lightning” to create aerosol nanoparticles ranging from single metals to unprecedented alloys (e.g., high-entropy alloys and immiscible alloys). Using these nanoparticles as building blocks, we also control their dynamic interplay with “lines of forces” to print 3D architectures, with nanometer-scale control over the size, orientations, and position of each nanostructure. Based on the understanding of the complex aerosol systems, we weave together various possibilities for unprecedented forms of matter–--from nanomanufacturing to 3D printing. The resulting structures can cover self-organized materials, active bio-inspired materials and metamaterials that have mechanical or optical or electrical properties that do not occur in nature. This highly promising discipline will open up new horizons in many fields, just name a few: nanoscale additive manufacturing (also known as 3D nanoprinting), chip technology, catalysts, microelectronics, photonics, nanofinishing and particle metallurgy. 
Currently we work on the following projects: ​
High-entropy alloy nanoparticles: the power of artificial lightening
This innovative invention will help resolving the limits encoutered in lighograpic technologies. We can print 3D architectures, with nanometer-scale control over the size, orientations, and position of each nanostructure. Based on the understanding of the complex aerosol systems, we weave together various possibilities for unprecedented forms of matter–from nanomanufacturing to 3D printing. We can then print 3D metamaterials, unique nanostructures for microelectronics and photonics, bioinspired materials et c, which can deliver new phenomena, new science, and new world that have been never conceived before! 
We develop an aerosol system to create alloy nanoparticles via vapor-crystal transformations. The technology used here is called spark mashup, which mixes the vapors and controls the composition of the alloy nanoparticles. This method also enables the breaking of miscibility limits and provides a plantform technology for creating unprecedented alloys, thereby opening up new horizons in many fields, such as new materials, metallurgy, catalysts, nanoscale addtive manufacturing, textile nanofinishing. 
3D nanoprinting: A foundamentally new technique        
Making fabrics with nanoparticles has been identified as a new research field called 'nanofinishing'. Resulting textiles provide added value to wearers. Challenges in nanofinishing are introducing more sustainable nanotechnologies to create durable smart textiles. Currently, nanofinishing is restricted by numerous constraints in traditional dip-pad-dry-cure processes. To combat these challenges, we develop more facile and sustainable nanofinishing based on the means of aerosol filtration.
