Title: Unlocking Catalytic Powers of Nonprecious Nanomaterials 


Although the precious metal-based materials are widely recognized as superior catalysts for clean energy applications, their large-scale commercial use has been hindered by their expensive and scarcity nature. The development of high performance, plentiful and cheap nonprecious materials based catalysts is therefore vital for the commercial viability of clean energy future. Unfortunately, the most of nonprecious materials in their pristine forms possess little or no catalytic activity. As such, unlocking the catalytic activities of nonprecious materials has become an important scientific task, but highly challenging.

This presentation reports a number of broadly applicable approaches to unlock the catalytic activities of nonprecious nanostructured materials. A number of examples from our recent investigations will be used to demonstrate the effectiveness and applicability of such approaches.[1-10]

Title:Near-Zero-Index Materials: New Avenues in Nonlinear Optics


The unlimited control of the amplitude and phase of a light wave has been a primary goal of optics since its inception. Recently, the advent of nanostructures materials, metamaterials, and metasurfaces have led to new approaches for manipulating the flow of light. However these devices are not as agile as desired because their functionality is generally defined at the time of fabrication. To extend the capabilities of such materials, tunability and dynamic control has been explored with many successes, and one promising candidate for control is nonlinear optics. Traditionally, nonlinear approaches have been difficult to achieve due to the small induced changes to the constituent material, but recent advances in materials have identified several potential platforms which can make photons talk more efficiently.

Here we will discuss and review the recent advances in nonlinear optical processes in near-zero-index materials, such as the doped oxides, including modelling methods and the ever important role of loss. Specifically, these materials have shown the ability to provide exceptional modulation to the nonlinear index (Δn ~ 1) whose sign can be controlled by varying the excitation parameters. This opens the opportunity for a new class of optical surface, one where the functionality is defined entirely through light.

Title: Additive manufacturing and iron-doped materials towards the design of multifunctional nanocomposite structures


Conceptual design, process selection, design steps, and design for manufacturing are important features in the Design for Additive Manufacturing (DfAM) method. The importance of Reverse Engineering (RE), Additive Manufacturing (AM), computer-aided design (CAD) and theoretical/experimental analyses has been already reported in the literature.
On the other hand, the control of the process–structure–property relationship of a material plays an important role in the design of devices featuring desired properties. Polymers, iron-doped materials and polymer-based nanocomposites have been designed and analyzed in different fields.
In the biomedical field, the applicability of porous structures and lattices has been widely discussed with a special focus on the design and fabrication of orthopedic implants and scaffolds for tissue regeneration. With regard to tissue engineering, 3D porous structures may be properly optimized for cell attachment and growth, as well as in terms of biocompatibility, degradation, bioresorbability, mass transport, and mechanical properties. Topology optimization and several issues related to homogenization and periodicity, as well as manufacturing constraints, have to be considered. Benefiting from the nanotechnology approach, nanomaterials and nanostructures have been widely developed and studied. As an effect of novel physical properties related to the nanoscale features, nanomaterials have more interesting properties in comparison to their microstructured counterparts. Functionalization strategies have also been employed to improve the surface properties of the developed devices.
It is through the combination of nanocomposites (i.e., polymers and iron-doped materials) and additive manufacturing that the present research is aimed at presenting the current advances in the design of advanced structures for industrial and biomedical applications

Title: Nanostructured materials for high efficiency thermoacoustic loudspeakers


The thermoacoustic (TA) loudspeaker technology is known since the beginning of the XXth century but the efficiency of the fabricated devices was strongly limited by the lack of suitable materials. It is now well understood that an efficient TA loudspeaker requires an active film with low heat capacity per unit area and a substrate with low thermal effusivity. The recent development of nanostructured materials, exhibiting unprecedented electrical, thermal, and mechanical properties, enabled the design and fabrication high efficiency TA loudspeakers. Solution processed metallic nanowires have been used for spray-coating deposition of nanostructured active films characterized by a low electrical resistance and an extremely low heat capacity per unit area. Silica aerogel has been selected for its low thermal effusivity, provided by the material nanoporous structure, and successfully used as substrate for TA loudspeakers. The experimental results show the significant enhancement achieved by using the presented nanostructured materials.

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
