Lab‐in‐a‐Tube System Integrating Hierarchically Wrinkled Electrodes and DNAzyme‐Functionalized Beads for Diagnosis of Clostridioides difficile Infection

Advanced Materials, EarlyView.
The point‐of‐care diagnosis of Clostridioides difficile infection remains challenging due to reliance on slow culture and amplification‐based methods. A lab‐in‐a‐tube electrochemical biosensor integrating DNAzymes, antifouling magnetic beads, and a hierarchically structured flow cell enables amplification‐ and culture‐free detection directly in stool ...

Atom–Cluster Synergy in Scalable Fe–Ru Dual‐Site Architectures Accelerates Alkaline Hydrogen Evolution

Advanced Materials, EarlyView.
A mechanochemically synthesized dual‐site electrocatalyst (RuNC@Fe1NC) accelerates alkaline hydrogen evolution via atomic‐level spatial decoupling. Oxophilic Fe single atoms effectively dissociate water, while adjacent Ru nanoclusters rapidly recombine hydrogen.

Radiofrequency and 2.45 GHz electron cyclotron resonance H− volume production ion sources

New Journal of Physics, 2016
The volume production of negative hydrogen ions ( ${{\rm{H}}}^{-}$ ) in plasma ion sources is based on dissociative electron attachment (DEA) to rovibrationally excited hydrogen molecules (H _2 ), which is a two-step process requiring both, hot electrons

Slow-electron-triggered chemistry in interstellar methanol-water ices

Astronomy & Astrophysics
Water and, to a lesser extent, methanol are widespread in interstellar space as ices, where sustained exposure to ionizing radiation promotes the formation of complex compounds such as prebiotic molecules via multi-step reactions.

Kinetics of electrons and neutral particles in radio-frequency transformer coupled plasma H− ion source at Seoul National University

New Journal of Physics, 2016
In volume production H ^− ion sources, control of electron temperature is essential due to its close correlation with the generation of vibrationally-excited hydrogen molecules in the driver region as well as the generation of H ^− ions by dissociative ...

Dissociative electron attachment to the HNC$_3$ molecule

Physical review letters
Dissociative electron attachment (DEA) to the HNC$_3$ is modeled theoretically using a first-principles approach. In HNC$_3$+$e^-$ collisions, there is a low-energy resonance, which has a repulsive character along the H+NC$_3$ coordinate and becomes a bound electronic state of the HNC$_3^-$ anion near the equilibrium of HNC$_3$.
