Title: Photo-Thermal Directed Assembly

Micro-patterning of various materials was recently developed based on the laser-induced microbubble technique (LIMBT). LIMBT relies on the formation of a microbubble due to laser heating of a dispersion of nanoparticles (NPs) that absorb the laser light. Natural and Marangoni convection currents carry the NPs to the bubble/substrate interface where some of them are pinned. Moving the substrate relative to the laser beam results in deposition of NPs along a predetermined path. Unfortunately, for many materials this deposition is non-continuous.

We have recently found¹ that controlling the construction and destruction of the microbubble through modulation of the laser enables the formation of continuous patterns by preventing the microbubble from getting pinned to the deposited material. Furthermore, we show that microstructure formation from an ion solution could be explained by a similar mechanism. Photo-thermal reduction of the ion solution leads to formation of NPs. These NPs are then pinned to the bubble/substrate interface. This innovative approach can be applicable for producing thin conductive patterns and allow fabrication of microelectronic devices and sensors.

Title: Bioinspired Micro/Nanostructured Surfaces with Wettability from Design to Functions

Biological surfaces provide endless inspiration for design and fabrication of smart materials. It has recently been revealed to have become a hot research area in materials and science world. Inspired by the roles of micro- and nanostructures in the water collecting ability of spider silk, a series of bioinspired gradient fibers has been designed by integrating fabrication methods and technologies such as fluid-coating, electrospinning-electrospraying, and web-assembly, etc., where the “spindle-knot/joint” structures with multiple gradients (e.g., roughness, curvature, etc.) can be realized to achieve functions of droplet transport, fog-harvesting, etc. In addition, the integrative conical spine materials with gradient micro- and nanostructures can be fabricated to achieve the ability of droplet transport in efficiency. Otherwise, the functional surfaces with micro- and nanostructures are developed to achieve the effect of water repellency by methods combining machining, electrospinning, soft lithography, and nanotechnology. These micro- and nanostructure surfaces with wettability exhibit robust transport and controlling of microdroplets, which would be promising applications.

Title: Fabrication of highly aligned CNT array and its application to strain sensors


We deposited the highly aligned multiwalled CNTs (MWCNTs) on a quartz substrate by chloride-assisted chemical vapor deposition [1-4]. The highly aligned MWCNTs are spinnable and can easily be spun into yarn by hand with the naked eye. The aligned CNT sheets were formed by stacking CNT webs drawn from spinnable CNT array. We have developed strain sensors using the aligned CNT sheets for detecting human motion [5]. In the presentation, we will present fabrication, characteristics of the highly aligned MWCNTs and their application to strain sensors for detecting human motion

Title: Improving Carbon Efficiency in Refractory Industry With Nanographite Brick Technology

Refractory is a key part on the production of all metals used by the modern society. Steel presents the highest demand on most of our day by day use from automotive exteriors to garbage cans and rail. The refractory industry is driven by the development of new or improved processes demanded by the customers and steel industry has been pointing out the tendency for high quality steel which requires sophisticated manufacturing technologies and decarburization rate for the low carbon content below 20ppm.

As the requirements for steel quality have become increasingly strict with strong demand for high strength and high toughness steel plates, a new refractory generation with extra low carbon was developed. Besides the advantages of energy economy in steel process and higher clean steel, another additional benefit includes less CO₂ emissions.

Extra low carbon bricks mean less thermal conductivity products and only can be achieved by replacing natural graphite by special nanographite. This new raw material was conceived to withstand the same oxidation resistance than natural flake graphite to compensate the nanoparticle size and also to achieve the desired properties to match the requirements for steel industry trials.

This work presents the nanographite approach to the real application in steel production with an expressive reduction in the amount of graphite from 5%wt to 1%wt. Properties and customer’s trial with nanographite bricks in steel ladle are also shown with improving carbon efficiency in an environmental friendly product.
