Aberration-Coreected Electron Microscopy at Brookhaven National Laboratory (open access)

Aberration-Coreected Electron Microscopy at Brookhaven National Laboratory

The last decade witnessed the rapid development and implementation of aberration correction in electron optics, realizing a more-than-70-year-old dream of aberration-free electron microscopy with a spatial resolution below one angstrom [1-9]. With sophisticated aberration correctors, modern electron microscopes now can reveal local structural information unavailable with neutrons and x-rays, such as the local arrangement of atoms, order/disorder, electronic inhomogeneity, bonding states, spin configuration, quantum confinement, and symmetry breaking [10-17]. Aberration correction through multipole-based correctors, as well as the associated improved stability in accelerating voltage, lens supplies, and goniometers in electron microscopes now enables medium-voltage (200-300kV) microscopes to achieve image resolution at or below 0.1nm. Aberration correction not only improves the instrument's spatial resolution but, equally importantly, allows larger objective lens pole-piece gaps to be employed thus realizing the potential of the instrument as a nanoscale property-measurement tool. That is, while retaining high spatial resolution, we can use various sample stages to observe the materials response under various temperature, electric- and magnetic- fields, and atmospheric environments. Such capabilities afford tremendous opportunities to tackle challenging science and technology issues in physics, chemistry, materials science, and biology. The research goal of the electron microscopy group at the Dept. of Condensed Matter Physics and …

Américo Paredes: in His Own Words, an Authorized Biography

Access: Use of this item is restricted to the UNT Community
Américo Paredes (1915-1999) was a folklorist, scholar, and professor at the University of Texas at Austin who is widely acknowledged as one of the founding scholars of Chicano Studies. Born in Brownsville, Texas, along the southern U.S.-Mexico Border, Paredes grew up between two worlds—one written about in books, the other sung about in ballads and narrated in folktales. After service in World War II, Paredes entered the University of Texas at Austin, where he completed his Ph.D. in 1956. With the publication of his dissertation, “With His Pistol in His Hand”: A Border Ballad and Its Hero in 1958, Paredes soon emerged as a challenger to the status quo. His book questioned the mythic nature of the Texas Rangers and provided an alternative counter-cultural narrative to the existing traditional narratives of Walter Prescott Webb and J. Frank Dobie. For the next forty years Paredes was a brilliant teacher and prolific writer who championed the preservation of border culture and history. He was a soft-spoken, at times temperamental, yet fearless professor. In 1970 he co-founded the Center for Mexican American Studies at the University of Texas at Austin and is credited with introducing the concept of Greater Mexico, decades before its …

Application of NMR Methods to Identify Detection Reagents for Use in the Development of Robust Nanosensors (open access)

Application of NMR Methods to Identify Detection Reagents for Use in the Development of Robust Nanosensors

Nuclear Magnetic Resonance (NMR) spectroscopy is a powerful technique for studying bi-molecular interactions at the atomic scale. Our NMR lab is involved in the identification of small molecules, or ligands that bind to target protein receptors, such as tetanus (TeNT) and botulinum (BoNT) neurotoxins, anthrax proteins and HLA-DR10 receptors on non-Hodgkin's lymphoma cancer cells. Once low affinity binders are identified, they can be linked together to produce multidentate synthetic high affinity ligands (SHALs) that have very high specificity for their target protein receptors. An important nanotechnology application for SHALs is their use in the development of robust chemical sensors or biochips for the detection of pathogen proteins in environmental samples or body fluids. Here, we describe a recently developed NMR competition assay based on transferred nuclear Overhauser effect spectroscopy (trNOESY) that enables the identification of sets of ligands that bind to the same site, or a different site, on the surface of TeNT fragment C (TetC) than a known ''marker'' ligand, doxorubicin. Using this assay, we can identify the optimal pairs of ligands to be linked together for creating detection reagents, as well as estimate the relative binding constants for ligands competing for the same site.

A Balancing Act: China’s Role in Climate Change (open access)

A Balancing Act: China’s Role in Climate Change

Climate change has reached the apex of the global agenda at a time when China faces significant development and energy security challenges. The political leadership and leading intellectuals are debating the direction of a new development pathway that provides both growth to meet development objectives, and dramatically reduces energy intensity and pollution. While the official position has not changed significantly, there are four key aspects that illustrate how climate change is conceived by the Chinese leadership. This signals that China may come to play a much more important role in global mitigation of climate change than was thought only a couple of years ago.
