Three-dimensional (3D) graphene-based structures combine the unique physical properties of graphene with the opportunity to get high electrochemically available surface area per unit of geometric surface area. Several preparation techniques have been reported to fabricate 3D graphene-based macroscopic structures for energy storage applications such as supercapacitors. Although reaserch has been focused so far on achieving either high specific capacitance or high volumetric capacitance, much less attention has been dedicated to obtain high specific and high volumetric capacitance simultaneously. Here, we present a facile technique to fabricate graphene foams (GF) of high crystal quality with tunable pore size grown by chemical vapor deposition. We exploited porous sacrificial templates prepared by sintering nickel and copper metal powders. Tuning the particle size of the metal powders and the growth temperature allow fine control of the resulting pore size of the 3D graphene-based structures smaller than 1 µm. -
Preparation of a Novel Structured Catalyst Based on Aligned Carbon
Catalysis Today 110 (2005) 47–52 www.elsevier.com/locate/cattod Preparation of a novel structured catalyst based on aligned carbon nanotube arrays for a microchannel Fischer-Tropsch synthesis reactor Ya-huei Chin, Jianli Hu, Chunshe Cao, Yufei Gao, Yong Wang * Institute of Interfacial Catalysis, Pacific Northwest National Laboratory, 902 Battelle Blvd, Richland, WA 99354, USA Available online 13 October 2005 Abstract A novel microstructured catalyst based on aligned multiwall carbon nanotube arrays was synthesized and tested for Fischer-Tropsch synthesis (FTS) reaction in a microchannel reactor. Fabrication of such a structured catalyst first involved metal organic chemical vapor deposition (MOCVD) of a dense Al2O3 thin film over FeCrAlY foam to enhance the adhesion between ceramic-based catalyst and metal substrate. Aligned multiwall carbon nanotubes were deposited uniformly over the substrate by controlled catalytic decomposition of ethylene. These nanotube bundles were directly attached to FeCrAlY foam through a submicron layer of oxide thin film. Coating the outer surfaces of these nanobundles with an active catalyst layer forms a unique hierarchical structure with fine interstitials between the carbon nanotube bundles. The microstuctural catalyst possessed superior thermal conductivity inherent from carbon nanotube, which allows efficient heat removal from catalytic active sites during exothermic FTS reaction. The concept was tested and demonstrated in a microchannel fixed bed FTS reactor. FTS turn-over activity was found to enhance by a factor of four owing to potential improvement in mass transfer in the unique microstructure. Furthermore, improved temperature control with the carbon nanotube arrays also allows the Fischer-Tropsch synthesis being operated at temperatures as high as 265 8C without reaction runaway. -
Elastomeric Foam Systems for Novel Mechanical Properties and Soft
ELASTOMERIC FOAM SYSTEMS FOR NOVEL MECHANICAL PROPERTIES AND SOFT ROBOT PROPRIOCEPTION A Dissertation Presented to the Faculty of the Graduate School of Cornell University In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy by Ilse Mae Van Meerbeek December, 2018 © 2018 Ilse Mae Van Meerbeek ELASTOMERIC FOAM SYSTEMS FOR NOVEL MECHANICAL PROPERTIES AND SOFT ROBOT PROPRIOCEPTION Ilse Mae Van Meerbeek, Ph.D. Cornell University 2018 Soft materials have enabled the fabrication of novel robots with interesting and complex capabilities. The same properties that have enabled these innovations—continuous deformation, elasticity, and low elastic moduli—are the same properties that make soft robotics challenging. Soft robots have limited load-bearing capabilities, making it difficult to use them when manipulation of heavy objects is needed, for example. The ability for soft robots to deform continuously makes it difficult to model and control them, as well as impart them with adequate proprioception. This dissertation presents work that attempts to address these two main challenges by increasing load-bearing ability and improving sensing. I present a composite material comprising an open-cell foam of silicone rubber infiltrated with a low melting-temperature metal. The composite has two stiffness regimes—a rigid regime at room temperature dominated by the solid metal, and an elastomeric regime at above the melting temperature of the metal, which is dictated by the silicone. I characterize the mechanical properties of the composite material and demonstrate its ability to hold different shapes, self-heal, and actuate using shape memory. In an advance for soft robotic sensing, I present a silicone foam embedded with optical fibers that can detect when it is being bent or twisted. -

The design pattern has a triangular-like structure and it consists of aligned wires. The structure was designed so that the distance between wires is 1 mm and the wire diameter is 1.2 mm. X-ray results showed that sample has a cubic structure with nm grains. Also, detailed element mapping indicated that sample has a homogenous distribution state of the reinforcement throughout the Al matrix, which also a clear indication of single phase. Compressive stress–strain curves shows the typical compressive behaviour of metallic foams consists of a narrow linear elastic area followed by a plateau regime and then a sharp increase.

Prior to the hybrid structures preparation, the nanocomposite foam formulation was optimized. The optimization consisted of studying the effect of the addition of graphene oxide (GO) and graphene nanoplatelets (GNPs) at different loadings (1.0, 2.5 and 5.0 wt%) during the polyurethane foam (PUF) formation, and their effect on the final nanocomposite properties. Globally, the results showed enhanced mechanical, acoustic and fire-retardant properties of the PUF nanocomposites when compared with pristine PUF. In a later step, the hybrid structure was prepared by embedding the Al-OC foam with the optimized nanocomposite formulation (prepared with 2.5 wt% of GNPs (PUF/GNPs2.5)). The process of filling the pores of the Al-OC was successfully achieved, with the resulting hybrid structure retaining low thermal conductivity values, around 0.038 W m 1 K 1, and presenting an improved sound absorption · − · − coefficient, especially for mid to high frequencies, with respect to the individual foams. -
3-D Vision for Welder Training and Production Welding
SUBCONTRACT NUMBER 2017-420 Panel Project Final Quarterly Report #4 for 3-D Vision for Welder Training and Production Welding Reporting Period: 9/1/17 – 12/1/17 Technical Progress/Major Accomplishments The team completed the second, final testing round o In-yard testing with experienced welders indicated that stereo was promising for blind / mirror welding o The in-school testing showed that the weld-by-video was very popular with students, but stereo was not judged to give any substantive training benefit; stereo seemed irrelevant. Dr. Foster presented his results at the NSRP joint panel meeting at Quonset RI, Sept 13. Details The team completed the second field testing round Because phase 1 found that students couldn’t appreciate the difference of stereo, the second testing phase focused on experienced welders. Mirror-welding tests were designed to differentiate the benefit of stereo (3D) over mono cameras by experienced welders. Tests were designed and executed by Dr. Foster of ODU as a subcontractor. Testing was done at 3 locations: Newport News Shipbuilding Austal Maritime Training Center Thomas Nelson Workforce Development Center Experienced welders successfully used the system to weld in blind spots where they would normally need a mirror to see. The experienced welders could effectively use the improvement of the video-view without worrying about how to weld. They liked the stereo over mono for general quality, but not specifically for depth perception. Stereo gives an improved look that is pleasing to the eye and brain. It just seems ‘better.’ Although the camera did provide depth perception, it remained awkward for the welders to get their hands into the proper position before the weld.
