Chemical and Physical Changes During Seawater Flow through Intact Dunite Cores: An Experimental study at 150-200 degC

October 1, 2017
Author(s)
Andrew J. Luhmann, Benjamin M. Tutolo, Brian C. Bagley, David F. Mildner, Peter P. Scheuermann, Joshua M. Feinberg, Konstantin Ignatyev, Jr. Seyfried
Two flow-through experiments were conducted to assess serpentinization of intact dunite cores. Permeability and fluid chemistry indicate significantly more reaction during the second experiment at 200 °C than the first experiment at 150°C. Permeability

Electron transport in bilayer graphene nanoconstrictions patterned using atomic force microscope nanolithography

March 20, 2025
Author(s)
Robert Rienstra, Nishat Sultana, En-Min Shih, Evan Stocker, Kenji Watanabe, Takashi Taniguchi, Curt Richter, Joseph Stroscio, Nikolai Zhitenev, Fereshte Ghahari Kermani
Here we report on low temperature transport measurements of encapsulated bilayer graphene nano constrictions fabricated employing electrode-free AFM-based local anodic oxidation (LAO) nanolithography. This technique allows for the creation of constrictions

Aflatoxin B1-induced DNA adduct formation in murine kidney and liver

January 31, 2025
Author(s)
Pawel Jaruga, Vladimir Vartanian, Irina Minko, M Miral Dizdar, Amanda McCullough, R. Stephen Lloyd
Aflatoxicosis is a life-threatening nephrotoxic condition arising from eating foods highly contaminated with aflatoxin-producing molds. Additionally, chronic aflatoxin exposures are linked to enhanced hepatocellular carcinomas. Using recent advances in

Byproduct Formation from Portable Air Cleaners under Standard Test Conditions

July 8, 2024
Author(s)
Dustin Poppendieck, Michael Link, Rileigh Robertson
Use of air cleaners has increased due to the COVID-19 pandemic and wildfire frequency. A wide range of air cleaning technologies have been implemented in various products, although the potential of these technologies to form byproducts is largely unknown

Effects of Octahedral Tilting on the Site of Substitution of Manganese in CaTiO3

January 22, 2021
Author(s)
Russell Maier, Kevin Garrity, Matthew P. Donohue, Andrzej Ozarowski, Igor Levin
Combined electron-paramagnetic-resonance and X-ray absorption spectroscopies with first principles calculations were used to investigate the substitutional behavior of Mn ions in perovskite CaTiO3 ceramics. While transition-metal dopants in perovskite

Effects of temperature and humidity on high-strength p-aramid fibers used in body armor

April 14, 2020
Author(s)
Amy E. Engelbrecht-Wiggans, Faraz A. Burni, Emilien Guigues, Shefei Jiang, Vivian Yu, Thang Huynh, Zois Tsinas, Deborah Jacobs, Amanda Forster
To improve the reliability and design of body armor, it is imperative to understand the failure modes and the degradation rates of the materials used in armor. Despite the best efforts of manufacturers, some vulnerability of armor materials to aging due to

Perovskite-Related ReO 3 -Type Structures

March 1, 2020
Author(s)
Hayden A Evans, Yue Wu, Ram Seshadri, Anthony K. Cheetham
ReO 3-type structures can be described as ABX 3 perovskites in which the A-cation site is unoccupied. They therefore have the general composition BX 3, where B is normally a cation and X is a bridging anion. The chemical diversity of such structures is
