This paper reports the engineering of large area cellular solids with controllable stiffness and specific strengths up to 230 MPa/(Mg/m(3)), which is stronger than most high strength alloys including 4143 steel and Ti-6Al-4V. The high strength arises from the size-based strengthening of the mn-sized struts. The cellular solid's porosity can be varied from 30 to 90% to control the specific stiffness from 4 - 20 GPa/(Mg/m(3)). The cellular solid's regular microporous architecture and self assembly based fabrication allow nanometer to micrometer control over the hierarchical geometry and chemistry, which enable large area materials with high strength and controllable stiffness.

Terahertz time-domain spectroscopy and its application towards measurements in biology
Özer, Zeynep; Altan, Hakan; Department of Physics (2016)
Terahertz Time-Domain Spectroscopy (THz-TDS) has proved to be an exceptional tool in measurements of biological and non-biological materials. The main reason why this method is preferred is that terahertz waves are typically harmless on samples due to the low excitation energy. Furthermore, one is able to extract parameters such as the absorption and refractive index easily directly from the data without using modeling. The low energy of the terahertz wave also makes it a useful tool for characterizing dyna...
Microwave sintering and characterization of soft magnetic powder metallurgical Ni-Fe alloys
Erdem, Derya; Dericioğlu, Arcan Fehmi; Department of Metallurgical and Materials Engineering (2011)
In this study, prealloyed austenitic stainless steel and premixed soft magnetic Ni-Fe permalloy compacts were consolidated through microwave and conventional sintering routes at combinations of various sintering temperatures and compaction pressures. Sintered alloys were characterized in terms of their densification, microstructural evolution as well as mechanical and magnetic properties. The effect of sintering method in terms of the applied sintering parameters on the final properties of the compacts were...
Long-term thermal stability of Equal Channel Angular Pressed 2024 aluminum alloy
TAN, Guher; Kalay, Yunus Eren; Gür, Cemil Hakan (2016-11-20)
The strength of bulk metallic materials can be improved by creating ultra-fine grained structure via severe plastic deformation (SPD). However, the thermal stability of severely deformed materials has been a major issue that restricts their practical use within the industry. Although there are studies on the thermal stability of SPD metals, the long-term annealing response of particularly complex alloys, such as the age hardenable ones, remains undetermined. In the present study, annealing behavior of the s...
Experimental Investigation of Strength of Curved Beam by Thin Ply Non-Crimp Fabric Laminates
Arca, M. A.; PAPİLA, MELİH; Çöker, Demirkan (2016-06-09)
Resistance against delamination failure and through the thickness tensile properties of curved carbon fiber reinforced plastics composites are investigated experimentally by conducting the curved beam strength tests. Effect of novel material thin ply non crimp fabric (NCF) architecture on delamination resistance of carbon fiber reinforced composites are investigated and compare with that of standard UD layups. In order to determine through the thickness tensile properties of curved carbon fiber composites, ...
Nanomaterial-Enhanced All-Solid Flexible Zinc-Carbon Batteries
Hiralal, Pritesh; Imaizumi, Shinji; Ünalan, Hüsnü Emrah; Matsumoto, Hidetoshi; Minagawa, Mie; Rouvala, Markku; Tanioka, Akihiko; Amaratunga, Gehan A. J. (2010-05-01)
Solid-state and flexible zinc carbon (or Leclanche) batteries are fabricated using a combination of functional nanostructured materials for optimum performance. Flexible carbon nanofiber mats obtained by electrospinning are used as a current collector and cathode support for the batteries. The cathode layer consists of manganese oxide particles combined with single-walled carbon nanotubes for improved conductivity. A polyethylene oxide layer containing titanium oxide nanoparticles forms the electrolyte laye...
