The Internal-Friction Tensor Q-1 iJ

October 12, 2021
Author(s)
Paul R. Heyliger, H M. Ledbetter, Sudook A. Kim
oustic-resonance spectroscopy enables obtaining the complete elastic-stiffness tensor C y in one measurement of the macroscopic-vibration frequencies of a regular-shape solid. Because the total elastic stiffness C y contains both real and imaginary parts

The Microwave Spectrum and Ground State Structure of H 2 O-HI

October 12, 2021
Author(s)
A McIntosh, T Walther, R R. Lucchese, J W. Bevan, R D. Suenram, A C. Legon
The microwave spectrum and ground state structure of H^ 2O HI are reported. The fitted ground state constants include: A 0=428.9 GHz, B 0=2189.7351(10) MHz, C 0=2175.9546(10) MHz, χ aa = -1479.399(20) MHz,(χ bb- χ cc) = -17.37(2) MHz. Evidence will be

The Mitochondrial Apoptosis-Induced Channel MAC and Bax Channels Are Regulated by Cytochrome C

October 12, 2021
Author(s)
Li Guo, D Pietkiewicz, M M. Pavlov, John J. Kasianowicz, L M. Dejean, S J. Korsmeyer, B Antonsson, K W. Kinnally
l-2 family proteins regulate the appearance of the high-conductance channel MAC (mitochondrial apoptosis-induced channel) 1 in the outer membranes of mitochondria early in apoptosis and regulate the release of cytochrome c during commitment to apoptosis

The Nanostructure Problem

October 12, 2021
Author(s)
Simon J. Billinge, Igor Levin
The powerful methods we have for solving the atomic structure of bulk crystals fail for nanostructured materials and there are currently no broadly applicable, quantitative and robust methods to replace them. The solution of this nanostructure problem is

The Role of Fluorine Chemistry in Anisotropic Etching of Dielectric Materials

October 12, 2021
Author(s)
B Ji, S A. Motika, P R. Badowski, S Dheandhanoo, C Timmons, D E. Hess, Eric C. Benck, Y Ye
Fluorine-containing compounds have for many years been utilized to etch dielectric materials such as silicon oxide. Maintaining the balance between the removal rate of material from the trench bottom and formation of the protective sidewall film is

The Spectrum of Singly Ionized Potassium, K II

October 12, 2021
Author(s)
K Pettersen, J O. Ekberg, I Martinson, Joseph Reader
Using 10.7 m and 3-m normal-incidence vacuum ultraviolet spectrographs, we investigated the spectrum of singly ionized potassium in the regions 495 612 and 1247 2150 . More than 120 new K II lines were identified. The previous work on this spectrum was

The Suppression of Orange-Peel Coupling in Magnetic Tunnel Junctions by Pre-Oxidation

October 12, 2021
Author(s)
William F. Egelhoff Jr., Robert McMichael, Cindi L. Dennis, Mark D. Stiles, Alexander J. Shapiro, Brian B. Maranville, Cedric J. Powell
We have have found that pre-oxidation of the bottom Co electrode in magnetic tunnel junctions (MTJs) very effectively suppresses orange-peel coupling. The result is a free layer that is much softer. Work by others has demonstrated that pre-oxidation is

The Thermodynamic Properties of 2,3-Dihydrobenzo[b]thiophene

October 12, 2021
Author(s)
W V. Steele, Robert D. Chirico, Anh D. Nguyen, S E. Knipmeyer
Measurements leading to the calculation of the standard thermodynamic properties for gaseous 2,3-dihydrobenzo[b]thiophene (ChemicalAbstracts registry number [4565-32-61]) are reported. Experimental methods included combustion calorimetry, adiabatic heat

Theory of Curvature and Grooving Effects in DIGM - II: the Mathematics

October 12, 2021
Author(s)
O Penrose, John W. Cahn
We examine and solve the mathematical problems that arise when diffusion induced grain boundary motion is formulated as a free boundary problem, i.e. as a system of partial differential equations on a moving curved interface with surface grooving as a

Theory of InP Nanocrystals Under Pressure

October 12, 2021
Author(s)
J G. Diaz-Garcia, Garnett W. Bryant, W Jaskolski
An empirical tight-binding theory which includes the effects of lattice relaxation is employed to investigate the opto-electronic properties of InP nanocrystals under an external hydrostatic pressure. For bulk InP, our model describes accurately the

Theory of Layer SMA Actuators

October 12, 2021
Author(s)
Alexander L. Roytburd, Julia Slutsker
Two types of multilayer actuators based on a shape memory alloy (SMA) film as an adtive component are explored theoretically. One of them uses the bending of an actuator due to the movement of an austenite/martensite interface of a SMA film parallel to a

Theory of Strain Percolation in Metals

October 12, 2021
Author(s)
R Thomson, Lyle E. Levine
We demonstrate that a deforming metal is a self organizing critical system, and that the stress-strain law can be expressed as an integration of certain derivatives of internal variables along the critical line of the system.

Thermal Limits on Field Alignment of Nanoparticle FePt Media

October 12, 2021
Author(s)
J A. Bain, William F. Egelhoff Jr.
We derive a simple expression for the angular distribution of ferromagnetic FePt particles an applied field in thermal equilibrium. This system is closely related to the Langevin expression for paramagnetic susceptibility, which computes the average
