A key objective of ongoing research rooted in molecular physics is to understand and precisely control chemical reactions at very low temperatures. At low temperatures, the chemical reactions between ...

Understanding how molecules interact with ions is a cornerstone of chemistry, with applications from pollution detection and cleanup to drug delivery. In a series of new studies led by JILA Fellow and ...

Metal ions bridging the grooves of two DNA helices explain how they lock together, the first direct look at the DNA zipper ...

Charge transfer dynamics in ion–molecule reactions govern a broad range of phenomena in environments as diverse as interstellar clouds, planetary atmospheres and laboratory plasmas. When a positively ...

A detailed study of a reaction between a molecular ion and a neutral atom has implications for both atmospheric and interstellar chemistry. Ion–neutral reactions are fundamentally different from those ...

Gas-phase ion–molecule reaction dynamics examine how charged species interact with neutral molecules under isolated conditions, revealing fundamental pathways that govern chemical reactivity in ...

Ions influence conductivity and mobility in molecular liquid crystals, affecting electrical behavior, stability, and performance in both established and emerging technologies. (Nanowerk Spotlight) The ...

Orthogonally arranged π-electronic systems that combine electron-donating and electron-accepting units display distinctive ...

The interaction between solid matter and positron (the antiparticle of electron) has provided important insights across a variety of disciplines, including atomic physics, materials science, ...

Schematic showing a single DNA duplex bridging two gold electrodes (yellow) patterned on a silicon nitride substrate (green). The setup allows measurement of electrical conductance as metal ions bind ...

Researchers have discovered how an ion channel in the brain's neurons has a kind of 'molecular memory', which contributes to the formation and preservation of lifelong memories. The researchers have ...
