Mars Ion and Neutral Particle Analyzer (MINPA) for Chinese Mars Exploration Mission (Tianwen-1): Design and ground calibration

open access: yesEarth and Planetary Physics, 2020
The main objective of the Mars Ion and Neutral Particle Analyzer (MINPA) aboard the Chinese Mars Exploration Mission (Tianwen-1) is to study the solar wind–Mars interaction by measuring the ions and energetic neutral atoms (ENAs) near Mars.

Ion/ion chemistry of high-mass multiply charged ions [PDF]

open access: yesMass Spectrometry Reviews, 1998
Electrospray ionization has enabled the establishment of a new area of ion chemistry research based on the study of the reactions of high-mass multiply charged ions with ions of opposite polarity. The multiple-charging phenomenon associated with electrospray makes possible the generation of multiply charged reactant ions that yield charged products as ...

30 Years of Lithium‐Ion Batteries

open access: yesAdvances in Materials, 2018
Over the past 30 years, significant commercial and academic progress has been made on Li‐based battery technologies. From the early Li‐metal anode iterations to the current commercial Li‐ion batteries (LIBs), the story of the Li‐based battery is full of ...

Distonoid ions [PDF]

open access: yesJournal of the American Society for Mass Spectrometry, 2006
By Yates, Bouma, and Radom's definition, distonic radical ions are those formally arising by ionization of diradicals or zwitterionic molecules (including ylides). These ions differ, therefore, from conventional radical ions by displaying the charge site and unpaired electron site (spin) localized mandatorily on separate atoms or group of atoms; that ...

Investigation of the effects of temperature and ions on the interaction between ECG and BSA by the fluorescence quenching method [PDF]

open access: yesArchives of Biological Sciences, 2011
The effects of temperature and common ions on binding (-)-epicatechin gallate (ECG) to bovine serum albumin (BSA) are investigated. The binding constants (Ka) between ECG and BSA are 1.20 Ч 106 (17°C), 1.38 Ч 106 (27°C), and 5.69 x 106 L mol-1 (37°C),

An ion trap-ion mobility-time of flight mass spectrometer with three ion sources for ion/ion reactions [PDF]

open access: yesJournal of the American Society for Mass Spectrometry, 2009
This instrument combines the capabilities of ion/ion reactions with ion mobility (IM) and time-of-flight (TOF) measurements for conformation studies and top-down analysis of large biomolecules. Ubiquitin ions from either of two electrospray ionization (ESI) sources are stored in a three dimensional (3D) ion trap (IT) and reacted with negative ions from

Imaging of Chemical Reactions Using a Terahertz Chemical Microscope

open access: yesPhotonics, 2019
This study develops a terahertz (THz) chemical microscope (TCM) that visualizes the distribution of chemical reaction on a silicon-based sensing chip. This chip, called the sensing plate, was fabricated by depositing Si thin films on a sapphire substrate

Pitch Angle Structures of Ring Current Ions Induced by Evolving Poloidal Ultra‐Low Frequency Waves

open access: yesGeophysical Research Letters, 2020
Ultra‐low frequency (ULF) waves can effectively accelerate ring current ions through drift‐bounce resonance. Conventional theories have been developed to understand this resonance since the dawn of the space age, which usually assume ULF waves are quasi ...
