Multi electrode harmonized Kingdon traps as mass analyzers for FT based mass spectrometers

Kingdon trap [1] is the simplest ion trap consisting of wire and cylindrical electrode surrounding with different potential.  Well-known Orbitrap [2], has emerged as development of R. D. Knight’s idea [3], who modified the cylinder electrodes geometry to make the field inside Kingdon trap quadratic (harmonic) and proposed measuring the frequencies of ions oscillating in such field by resonant excitation of their motion along trap axis, to determine their masses [3].

Surf, Sink or Swim: Understanding Environmentally Important Processes at Water Surfaces

Although the special properties of water have been valued and appreciated for centuries, as scientists we continue to be perplexed by the molecular make-up of water in all its forms.  Equally perplexing is the surface of water, a surface that is involved in some of most important reactions in our atmosphere, a surface that can sculpt the landscape as it flows past rocks and soils, a surface that can break down the strongest of metals, and a surface across which essential nutrients and ions are constantly exchanged in life-susta

AAAS Workshop Award to Chemistry Graduate Student

Cynthia Tope, a graduate student in the UGA Chemistry Department, has been awarded a sponsorship by the UGA Graduate School to attend the 2019 Catalyzing Advocacy in Science and Engineering (CASE) workshop hosted by the American Association for the Advancement of Science. Cynthia is currently a third-year student under the direction of Dr. Jeffrey Urbauer. She is one of only two UGA graduate students to be awarded this sponsorship.
