Composite Electrode for High Performance Ultracapacitors and Batteries

Brambilla N., Rich D., Park K., Ndiritu S., Nanoramic Laboratories, US

The standard electrodes used in today’s energy storage devices contain a passive organic or polymeric binder. This material affects various electrochemical performance characteristics of an electrode and lowers power density, energy density, and reliability of [...]

Determining the Quality of Asphalt Emulsions by Size and Zeta Potential

Ragheb R., Park K., Nobbmann U., Casola J., Malvern Panalytical, US

Asphalt binder emulsions have proven to be an environmentally friendly, energy efficient, and cost-effective alternative to hot asphalt binder mixtures [1]. They are typically used for roadway resurfacing where they are employed as an adhesive [...]

Comparing Nanorulers for Nanoparticles

Bodycomb J., Bath F., Treviranus I., Park K., Hou A., Horiba Scientific, US

Nanoparticle development and manufacturing require particle characterization to determine if design or quality goals are being met. Scattering techniques are the method of choice for analyzing average size and size distribution. There are two light [...]

Design and Development of a Large-Scale Compressed Earth Block Building System for Developed Countries

Tate D., Ertas A., Maxwell T., Park K., Lawson W., Texas Tech University, US

Designers of building systems of today and tomorrow must approach energy, environmental, and economic considerations in a holistic manner. Energy and resource consumption for building systems consist not only of energy use during the occupancy [...]

Synthesis of Janus Nanorods for Assemblies of Thermoresponsive Rod Pairs

MacCuspie R.I., Park K., Naik R., Vaia R.A., Air Force Research Lab, US

Janus particles offer unique functionality; for example micron-scale Janus spheres are used for electronic paper. At the nanoscale, reproducible, scalable fabrication of Janus particles is one of the key enabling technologies for “bottom-up” assembly processes. [...]

Nanoparticulate Drug Delivery Systems Based on Hydrotropic Polymers, Dendrimers, and Polymer Complexes

Park J.H., Park K., Huh K.M., Lee S-C, Lee W-K, Lee S-C, Lee W-K, Ooya T., Park J.H., Park K., Purdue University, US

Novel nanoparticulate drug delivery systems have received increasing attention for delivery of poorly water-soluble drugs and proteins. We have developed a new type of polymer micelles bearing the hydrotropic core segment, e.g., poly(2-(4-vinylbenzyloxy)-N,N-diethylnicotinamide), that enables [...]
