Item Low-Cost Manufacturing of Metal-Ceramic Composites through Electrodeposition of Metal into Ceramic Scaffold(Amer Chemical Soc, 2019-01) Huang, Jiacheng; Daryadel, Soheil; Minary-Jolandan, Majid; 0000-0003-2472-302X (Minary-Jolandan, M); Huang, Jiacheng; Daryadel, Soheil; Minary-Jolandan, MajidInfiltration of a molten metal phase into a ceramic scaffold to manufacture metal-ceramic composites often involves high temperature, high pressure, and expensive processes. Low-cost processes for fabrication of metal-ceramic composites can substantially increase their applications in various industries. In this article, electroplating (electrodeposition) as a low-cost, room-temperature process is demonstrated for infiltration of metal (copper) into a lamellar ceramic (alumina) scaffold. Estimation shows that this is a low energy consumption process. Characterization of mechanical properties showed that metal infiltration enhanced the flexural modulus and strength by more than 50% and 140%, respectively, compared to the pure lamellar ceramic. More importantly, metal infiltration remarkably enhanced the crack initiation and crack growth resistance by more than 230% and 510% compared to the lamellar ceramic. The electrodeposition process for development of metal-ceramic composites can be extended to other metals and alloys that can be electrochemically deposited, as a low-cost and versatile process.Item Toward Control of Microstructure in Microscale Additive Manufacturing of Copper Using Localized Electrodeposition(Wiley-VCH Verlag GmbH, 2019-01) Daryadel, Soheil; Behroozfar, Ali; Minary-Jolandan, Majid; Minary-Jolandan, MajidThe progress in microscale additive manufacturing (μ-AM) of metals requires engineering of the microstructure for various functional applications. In particular, achieving in situ control over the microstructure during 3D printing is critical to eliminate the need for post-processing and annealing. Recent reports have demonstrated the possibility of electrochemical μ-AM of nanotwinned metals, in which the presence of parallel arrays of twin boundaries (TBs) are known to enhance mechanical and electrical properties. For the first time, the authors report that the microstructure of metals printed using the microscale localized pulsed electrodeposition (L-PED) process can be controlled in situ during 3D-printing. In particular, the authors show that through electrochemical process parameters the density and the orientation of the TBs, as well as the grain size can be controlled. The results of the in situ SEM microcompression experiments on directly 3D-printed micro-pillars show that such control over microstructure directly correlates with the mechanical properties of the printed metal.Item Enhancement of the Electrical Properties of DNA Molecular Wires Through Incorporation of Perylenediimide DNA Base Surrogates(Wiley-vch Verlag, 2019-04-25) Lin, Kuo-Yao; Burke, A.; King, Nolan B.; Kahanda, Dimithree; Mazaheripour, A.; Bartlett, A.; Dibble, D. J.; McWilliams, Mark A.; Taylor, David W.; Jocson, J. -M; Minary-Jolandan, Majid; Gorodetsky, A. A.; Slinker, Jason D.; Lin, Kuo-Yao; King, Nolan B.; Kahanda, Dimithree; McWilliams, Mark A.; Taylor, David W.; Minary-Jolandan, Majid; Slinker, Jason D.DNA has long been viewed as a promising material for nanoscale electronics, in part due to its well-ordered arrangement of stacked, pi-conjugated base pairs. Within this context, a number of studies have investigated how structural changes, backbone modifications, or artificial base substitutions affect the conductivity of DNA. Herein, we present a comparative study of the electrical properties of both well-matched and perylene-3,4,9,10-tetracarboxylic diimide (PTCDI)-containing DNA molecular wires that bridge nanoscale gold electrodes. By performing current-voltage measurements for such devices, we find that the incorporation of PTCDI DNA base surrogates within our macromolecular constructs leads to an approximately 6-fold enhancement in the observed current levels. Together, these findings suggest that PTCDI DNA base surrogates may enable the preparation of designer DNA-based nanoscale electronic components. © 2019 Wiley-VCH Verlag GmbH & Co. KGaA, WeinheimItem Multi-Physics Simulation of Metal Printing at Micro/Nanoscale Using Meniscus-Confined Electrodeposition: Effect of Nozzle Speed and Diameter(American Institute of Physics Inc, 2018-08-31) Morsali, Seyedreza; Daryadel, Soheil; Zhou, Zhong; Behroozfar, Ali; Baniasadi, Mahmoud; Moreno, Salvador; Qian, Dong; Minary-Jolandan, Majid; Morsali, Seyedreza; Daryadel, Soheil; Zhou, Zhong; Behroozfar, Ali; Baniasadi, Mahmoud; Moreno, Salvador; Qian, Dong; Minary-Jolandan, MajidMeniscus-confined electrodeposition (MCED) is a solution-based, room temperature process for 3D printing of metals at micro/nanoscale. In this process, a meniscus (liquid bridge or capillary) between a nozzle and a substrate governs the localized electrodeposition process, which involves multiple physics of electrodeposition, fluid dynamics, mass, and heat transfer. We have developed a multiphysics finite element (FE) model to investigate the effects of nozzle speed (v N) and nozzle diameter (D0) in the MCED process. The simulation results are validated with experimental data. Based on theoretical approach and experimental observation, the diameter of the deposited wire is in the range of 0.5-0.9 times of the nozzle diameter. The applicable range for vN for various nozzle diameters is computed. The results showed that the contribution of migration flux to total flux remains nearly constant (∼50%) for all values of pipette diameter in the range examined (100 nm-5 μm), whereas the contribution of diffusion and evaporation fluxes to total flux increase and decrease with the increasing pipette diameter, respectively. Results of this multiphysics study can be used to guide the experiment for optimal process conditions. © 2017 Author(s).Item Alginate-Collagen Fibril Composite HydrogelBaniasadi, Mahmoud; Minary-Jolandan, MajidWe report on the synthesis and the mechanical characterization of an alginate-collagen fibril composite hydrogel. Native type I collagen fibrils were used to synthesize the fibrous composite hydrogel. We characterized the mechanical properties of the fabricated fibrous hydrogel using tensile testing; rheometry and atomic force microscope (AFM)-based nanoindentation experiments. The results show that addition of type I collagen fibrils improves the rheological and indentation properties of the hydrogel.Item Nanomechanical Imaging of Soft Samples in Liquid Using Atomic Force MicroscopyMinary-Jolandan, Majid; Yu, M. -FThe widely used dynamic mode atomic force microscopy (AFM) suffers severe sensitivity degradation and noise increase when operated in liquid. The large hydrodynamic drag between the oscillating AFM cantilever and the surrounding liquid overwhelms the dissipative tip-sample interaction forces that are employed for nanomechanical imaging. In this article, we show that the recently developed Trolling-Mode AFM based on a nanoneedle probe can resolve nanomechanical properties on soft samples in liquid, enabled by the significantly reduced hydrodynamic drag between the cantilever and the liquid. The performance of the method was demonstrated by mapping mechanical properties of the membrane of living HeLa cells.
