Direct measurement of the 3P0 clock state natural lifetime in 87Sr

August 24, 2025
Author(s)
Kyle Beloy, Jonathan Dolde, Dhruva Ganapathy, Xin Zheng, Shuo Ma, Shimon Kolkowitz
Optical lattice clocks based on the narrow transition between (5s2)1S0 -(5s5p)3P0 levels in neutral strontium (Sr) are among the most precise and accurate measurement devices in existence. Although this transition is completely forbidden by selection rules

An Electrically Conducting Metal-Organic Framework Having Two Orthogonal Transport Pathways

December 12, 2024
Author(s)
Shiyu Zhang, Weikang Zhang, Ashok Yadav, Md. Ansari, Jonathan Cromer, Jorge Moreno, Gavin McCarver, Wei Zhou, Sourav Saha
Owing to their diverse potential applications in electronics and energy technologies, electrically conducting metal–organic frameworks (EC-MOFs) have emerged as one of the most coveted functional materials of the twenty-first century. Among various MOF

DNA-directed nanofabrication of high-performance carbon nanotube field-effect transistors

May 22, 2020
Author(s)
Ming Zheng, Jeffrey A. Fagan, Jason K. Streit, Mengyu Zhao, Yahong Chen, Kexin Wang, Zhi Zhu, Wei Sun
Scaling the channel pitch of field-effect transistors (FETs) is one prerequisite towards future ultra-scaled technology nodes. While lithography has been the foundational tool during the scaling of bulk materials, bio- fabrication is promising for

Reaction Kinetics in Ionic Liquids as Studied by Pulse Radiolysis: Redox Reactions in the Solvents Methyltributylammonium Bis(trifluoroniethyl-sulfonyl)imide and N-Butylpyridinium Tetrafluoroborate

April 1, 2002
Author(s)
D Behar, Pedatsur Neta, C R. Schultheisz
Rate constants for several reduction and oxidation reactions were determined by pulse radiolysis in three ionic liquids and compared with rate constants in other solvents. Radiolysis of the ionic liquids methyltributylammonium bis(trifluoromethylsulfonyl

Final report: Ecotoxicity of PFAS-Free Fire Fighting Foams: Fish and Aquatic Invertebrate Species ER20-1518

February 27, 2026
Author(s)
Edward Wirth, Marie DeLorenzo, Peter Key, Katy Chung, David Moore, Guilherme Lotufo, John Kucklick, Katherine Peter, Jessica Reiner
The Department of Defense (DoD) is actively engaging in research to identify fluorine free foams (F3) that do not contain per- and poly-fluorinated alkyl substances (PFAS) as replacements for traditional Aqueous Film Forming Foams (AFFF) products that

Characterization of the Alloy-Solution Interface

October 16, 2008
Author(s)
H J. Mueller
For metals undergoing corrosion, a layer of water molecules becomes charged due to electrons accumulating on the outer metal surface and hydrated positive ions in solution adjacent to the surface. The layer has properties of capacitance (C dl) and
