    • Transport mechanism in granular Ni deposited on carbon nanotubes fibers 

      Salvato, M.; Lucci, M.; Ottaviani, I.; Cirillo, M.; Tamburri, E.; Orlanducci, S.; Terranova, M.L.; Notarianni, M.; Young, C.C.; Behabtu, N.; Pasquali, M. (2012)
      We investigate the transport properties of granular nickel electrodeposited on carbon nanotube fibers by measuring the electrical resistance and the current voltage characteristics as a function of the temperature. The ...
    • Treating Water by Degrading Oxyanions Using Metallic Nanostructures 

      Yin, Yiyuan B.; Guo, Sujin; Heck, Kimberly N.; Clark, Chelsea A.; Coonrod, Christian L.; Wong, Michael S. (2018)
      Consideration of the water–energy–food nexus is critical to sustainable development, as demand continues to grow along with global population growth. Cost-effective, sustainable technologies to clean water of toxic ...
    • Tumor microenvironment derived exosomes pleiotropically modulate cancer cell metabolism 

      Zhao, Hongyun; Yang, Lifeng; Baddour, Joelle; Achreja, Abhinav; Bernard, Vincent; Moss, Tyler; Marini, Juan C.; Tudawe, Thavisha; Seviour, Elena G.; San Lucas, F. Anthony; Alvarez, Hector; Gupta, Sonal; Maiti, Sourindra N.; Cooper, Laurence; Peehl, Donna; Ram, Prahlad T.; Maitra, Anirban; Nagrath, Deepak (2016)
      Cancer-associated fibroblasts (CAFs) are a major cellular component of tumor microenvironment in most solid cancers. Altered cellular metabolism is a hallmark of cancer, and much of the published literature has focused on ...
    • Two distinctive energy migration pathways of monolayer molecules on metal nanoparticle surfaces 

      Li, Jiebo; Qian, Huifeng; Chen, Hailong; Zhao, Zhun; Yuan, Kaijun; Chen, Guangxu; Miranda, Andrea; Guo, Xunmin; Chen, Yajing; Zheng, Nanfeng; Wong, Michael S.; Zheng, Junrong (2016)
      Energy migrations at metal nanomaterial surfaces are fundamentally important to heterogeneous reactions. Here we report two distinctive energy migration pathways of monolayer adsorbate molecules on differently sized metal ...
    • Two-Step Adsorption of a Switchable Tertiary Amine Surfactant Measured Using a Quartz Crystal Microbalance with Dissipation 

      Chen, Yi-Lin; Zhang, Leilei; Song, Jin; Jian, Guoqing; Hirasaki, George; Johnston, Keith; Biswal, Sibani Lisa (2019)
      The adsorption of a switchable cationic surfactant, N,N,N′-trimethyl-N′-tallow-1,3-diaminopropane (DTTM, Duomeen TTM), at the silica/aqueous solution interface is characterized using a quartz crystal microbalance with ...
    • Unimolecular Submersible Nanomachines. Synthesis, Actuation, and Monitoring 

      García-López, Víctor; Chiang, Pinn-Tsong; Chen, Fang; Ruan, Gedeng; Martí, Angel A.; Kolomeisky, Anatoly B.; Wang, Gufeng; Tour, James M. (2015)
      Unimolecular submersible nanomachines (USNs) bearing light-driven motors and fluorophores are synthesized. NMR experiments demonstrate that the rotation of the motor is not quenched by the fluorophore and that the motor ...
    • Using Nonionic Surfactants for Production of Semiconductor-type Carbon Nanotubes by Gel-based Affinity Chromatography 

      Gangoli, Varun Shenoy; Azhang, Juyan; Willett, Taryn T.; Gelwick, Sean A.; Haroz, Erik H.; Kono, Junichiro; Hauge, Robert H.; Wong, Michael S. (2014)
      Single-wall carbon nanotubes (SWCNTs) have remarkable properties based on their electronic properties, i.e., metallic or semiconducting types, but as-grown SWCNTs contain a mixture of both types. Presented here is an ...
    • Visualizing oil displacement with foam in a microfluidic device with permeability contrast 

      Conn, Charles A.; Ma, Kun; Hirasaki, George J.; Biswal, Sibani Lisa (2014)
      Foam mobility control and novel oil displacement mechanisms were observed in a microfluidic device representing a porous media system with layered permeability. Foam was pre-generated using a flow focusing microfluidic ...
    • Volcano-shape glycerol oxidation activity of palladium-decorated gold nanoparticles 

      Zhao, Zhun; Arentz, Joni; Pretzer, Lori A.; Limpornpipat, Pongsak; Clomburg, James M.; Gonzalez, Ramon; Schweitzer, Neil M.; Wu, Tianpin; Miller, Jeffrey T.; Wong, Michael S. (2014)
      Bimetallic PdAu catalysts are more active than monometallic ones for the selective oxidation of alcohols, but the reasons for improvement remain insufficiently detailed. A metal-on-metal material can probe the structure–catalysis ...
    • Wertheim's association theory applied to one site patchy colloids: Beyond the single bonding condition 

      Marshall, Bennett D.; Ballal, Deepti; Chapman, Walter G. (2012)
      We apply Wertheim's theory to develop an equation of state for one site patchy colloids where the patch can bond multiple times. We allow for the possibility of ring formation without the introduction of empirical parameters ...
