New routes to novel oeganofluorine compounds [PDF]

, 1989
Use of the carbon hydrogen bond as a functional group in free radical addition reactions to fluorinated olefins has been studied. Using cyclic ethers a detailed investigation of the products obtained revealed that not only carbon hydrogen bonds a to ...

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Perfluoroalkylation of aromatic systems [PDF]

, 1997
I. We have concentrated on the synthesis of aromatic systems containing CH(_2)R(_F) groups, where R(_F) is a bulky group derived from hexafluoropropene dimer, using fluoride ion induced methodology.

Recent Advances (2023–2025) of Capillary Electrophoresis‐Mass Spectrometry (CE‐MS) for Top‐Down Proteomics

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Top‐down proteomics (TDP) characterizes proteoforms in cells, tissues, and biofluids, in discovery mode and on a global scale, requiring analytical tools with high peak capacity for proteoform separation and high sensitivity for proteoform detection, given the extremely high proteoform complexity and wide proteoform concentration dynamic range.

Sustainable Management of Banked Fluorocarbons as a Cost-Effective Climate Action

Fluorocarbon banks present a substantial yet largely untapped opportunity for climate change mitigation within current regulatory frameworks. This potential can be effectively addressed through fluorocarbon lifecycle management (FLM), a strategy grounded

Scaling turbulence drives the general circulation

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The NOAA Gulfstream SP4, which deployed the GPS dropsondes over the NE Pacific Ocean as part of the Winter Storms Project during the January–March periods of 2004, 2005 and 2006. Abstract Statistical multifractal analysis of airborne and dropsonde observations is used to show that persistence of velocity after molecular collisions breaks the continuous

Precisely Timed On‐Demand Droplet Ejection and Collision in Free Space for Controlled Reaction Initiation

Small, EarlyView.
LiDIA is an on‐demand droplet‐in‐air platform that enables synchronized droplet collision, ultralow‐waste operation, and obstruction‐free sample delivery. By combining precise triggering with reliable free‐space dispensing, it provides a versatile route for rapid mixing and time‐resolved studies, with strong potential for applications in XFEL, cryo‐EM,
