Complementary use of TEM and APT for the investigation of steels nanostructured by severe plastic deformation

, 2009
The properties of bulk nanostructured materials are often controlled by atomic scale features like segregation along defects or composition gradients.

Introduction: Special Issue on Atom Probe Tomography [PDF]

Microscopy and Microanalysis, 2007
In February 2006, in conjunction with the 19th Australian Conference on Microscopy and Microanalysis held in Sydney, the 2nd Australian Workshop on Atom Probe Tomography was convened by S.P. Ringer, M.K. Miller, D.A. Saxey, and R. Zheng at the Australian Key Centre for Microscopy and Microanalysis at The University of Sydney. The topics covered at that

Direct measurement of the quantum state of photons in a cavity

, 2018
We propose a scheme to measure the quantum state of photons in a cavity. The proposal is based on the concept of quantum weak values and applies equally well to both the solid-state circuit and atomic cavity quantum electrodynamics (QED) systems.

Comment on "Atomic Scale Structure and Chemical Composition across Order-Disorder Interfaces"

, 2011
Interfaces have long been known to be the key to many mechanical and electric properties. To nickel base superalloys which have perfect creep and fatigue properties and have been widely used as materials of turbine blades, interfaces determine the ...

Nanoscale austenite reversion through partitioning, segregation, and kinetic freezing: Example of a ductile 2 GPa Fe-Cr-C steel

, 2012
Austenite reversion during tempering of a Fe-13.6Cr-0.44C (wt.%) martensite results in an ultrahigh strength ferritic stainless steel with excellent ductility.

Field evaporation of germanium under THz pulses: application to atom probe tomography [PDF]

APL Materials
This study investigates the field evaporation behavior of germanium (Ge) under monocycle terahertz (THz) excitation using atom probe tomography (APT). The influence of THz pulse polarity, specimen geometry, and spectral content is systematically examined.

Jaynes-Cummings dynamics with a matter wave oscillator

, 2002
We propose to subject two Bose-Einstein condensates to a periodic potential, so that one condensate undergoes the Mott insulator transition to a state with precisely one atom per lattice site.

Atomic-scale age resolution of planetary events

Nature Communications, 2017
Constraining the timing of crustal processes and impact events remains challenging. Here, the authors show that atom probe tomography can produce highly accurate U-Pb isotopic age constraints in baddeleyite crystals, which is a common phase in ...

An Effective Method to Estimate Composition Amplitude of Spinodal Decomposition for Atom Probe Tomography Validated by Phase Field Simulations

, 2012
Reasonable evaluation of composition amplitude in spinodal decomposition is a challenge to microanalysis of atom probe tomography, especially at early stages when phase separation is not prominent. This impedes quantitative analysis of spinodal structure
