Precision Measurement of Transition Matrix Elements via Light Shift Cancellation

, 2012
We present a method for accurate determination of atomic transition matrix elements at the 10^{-3} level. Measurements of the ac Stark (light) shift around "magic-zero" wavelengths, where the light shift vanishes, provide precise constraints on the ...

Ionic Liquid‐Enhanced 3D Printed Flexible Resin for Pressure‐Sensing Applications

Advanced Materials Technologies, EarlyView.
A 3D‐printed resin–ionic liquid (IL) composite forms gyroid ionotronic architectures showing dynamic ionic migration under compression. Impedance analysis reveals distinct frequency responses across three topologies at high IL concentrations.

A review of atomic clock technology, the performance capability of present spaceborne and terrestrial atomic clocks, and a look toward the future [PDF]

Clocks have played a strong role in the development of general relativity. The concept of the proper clock is presently best realized by atomic clocks, whose development as precision instruments has evolved very rapidly in the last decades.

Time synchronization via the transit satellite at Mizusawa [PDF]

, 1978
Time signals emitted from Transit satellites and received by the NAVICODE type receiver at Mizusawa, Japan are presented. The International Latitude Observatory of Mizusawa and the U. S. Naval Observatory were compared using the time signals. Propagation

Ductility Tuning via Cluster Network Characteristics of Porous Components

Advanced Materials Technologies, EarlyView.
Network optimization via cluster characteristics induced by interaction of stress concentration is proposed, demonstrating increased cluster size and dispersion in non‐uniform porous components. The optimized structures exhibit, for the first time, that enhanced ductility and damage progression is controllable through zigzag cluster network designed by

Amido‐Amine Co(II) Precursor‐Based Atomic/Molecular Layer Deposition Processes for Cobalt‐Organic Thin Films and Their Thermal Conversion to CoO Thin Films

Advanced Materials Technologies, EarlyView.
Three new atomic/molecular layer deposition processes are developed for Co‐organic thin films using a promising all‐nitrogen‐coordinated cobalt precursor. The study examines film growth, reaction mechanisms, chemical stability, and decomposition pathways of the resulting films through extensive characterization techniques and DFT calculations ...
