Stable Interface Formation between TiS 2 and LiBH 4 in Bulk-Type All-Solid-State Lithium Batteries

August 11, 2015
Author(s)
Atsushi Unemoto, Tamio Ikeshoji, Syun Yasaku, Motoaki Matsuo, Vitalie Stavila, Terrence J. Udovic, Shin-Ichi Orimo
In this study, we assembled a bulk-type all-solid-state batter comprised of a TiS 2 positive electrode, LiBH 4 electrolyte, and Li negative electrode. Our battery retained high capacity over 300 discharge-charge cycles when operated at 393 K and 0.2 C. The

UV-induced photochemical transformations of citrate capped silver nanoparticle suspensions

September 14, 2012
Author(s)
Justin M. Gorham, Robert I. MacCuspie, Kate L. Klein, D H. Fairbrother, Richard D. Holbrook
Due to the increasing use of silver nanoparticles (AgNPs) in consumer products, it is essential to understand how variables, such as light exposure, may change the physical and chemical characteristics of AgNP suspensions. To this end, the effect of 300 nm

Core-shell composite of SiCN and multiwalled carbon nanotubes from Toluene dispersion

May 21, 2010
Author(s)
John H. Lehman, Katherine E. Hurst, Gurpreet Singh, Elisabeth Mansfield, John D. Perkins, Christopher L. Cromer
Carbon nanotubes are known to have high thermal conductivity, and in bulk form, a topology that could constitute the matrix of an inhomogeneous solid. Among the promised applications of carbon nanotubes is a composite material that is practical for thermal

Heat Release Mechanisms in Inhibited Laminar Counterflow Flames (Journal)

January 1, 1996
Author(s)
Ki Y. Lee, Don J. Cha, Anthony Hamins, I K. Puri
Due to the participation of inhibitors in flame chemistry, it is difficult to concurrently characterize the complex interaction between their cooling action, and the chemical inhibition (which decrease temperature), and their contribution of heat release

Chemical characteristics of indoor aerosol particles and surface films

July 8, 2024
Author(s)
Rachel O'Brien, Cate Shirilla, Amy Hrdina, Emily Legaard, Kathryn Mayer, Marina Vance, Dustin Poppendieck, Delphine Farmer
Indoor surfaces and the films on them play important roles in indoor air quality due to the high surface area to volume ratios in our homes. The chemical complexity of these films can be large, and this can increase after film formation as the chemicals in

Quartz Crystal Microbalances for Microscale Thermogravimetric Analysis

June 20, 2010
Author(s)
Elisabeth Mansfield, Aparna Kar, Stephanie A. Hooker
A new method for analyzing the chemical purity and consistency of microscale samples is described using a quartz crystal microbalance (QCM) sensor platform. The QCM is used to monitor sub-picogram changes in the mass of a deposited thin film as a function

Thermal Plasma Synthesis of Magnetic Nanoparticles

October 16, 2008
Author(s)
J H. Scott, S. A. Majetich, Z Turgut, M E. McHenry, K Chowdary, M I. Boulos
A scalable synthesis route for the production of bare and carbon-coated metal nanoparticles is presented. Magnetic nanoparticles composed of pure Fe, pure Co, and FeCo alloys ranging from Fe 50Co 50 to Fe 75Co 25 are produced using a radio frequency (RF)
