Coupled-channels density-matrix approach to low-energy nuclear reaction dynamics

, 2010
Atomic nuclei are complex, quantum many-body systems whose structure manifests itself through intrinsic quantum states associated with different excitation modes or degrees of freedom.

Hydroxyl super rotors from vacuum ultraviolet photodissociation of water

Nature Communications, 2019
Free electron lasers provide a state-of-the-art tool to investigate the photochemistry of water. Here, the authors show that highly rotationally excited hydroxyl radicals, so-called “super rotors” existing above the bond dissociation energy, are observed

Mechanisms of triplet energy transfer across the inorganic nanocrystal/organic molecule interface

Nature Communications, 2020
Though literature reports models describing triplet energy transfer between inorganic semiconductors and organic molecules, a unified mechanism for this process is still lacking.

Three body photodissociation of the water molecule and its implications for prebiotic oxygen production

Nature Communications, 2021
Three-body dissociation of water, producing one oxygen and two hydrogen atoms, has been difficult to investigate due to the lack of intense vacuum ultraviolet sources.

On the dynamics of chemical reactions of negative ions

, 2010
This review discusses the dynamics of negative ion reactions with neutral molecules in the gas phase. Most anion-molecule reactions proceed via a qualitatively different interaction potential than cationic or neutral reactions.

Ultrafast structural dynamics of carbon–carbon single-bond rotation in transient radical species at non-equilibrium

Nature Communications
Bond rotation is an important phenomenon governing the fate of reactions. In particular, heterogeneously substituted ethane derivatives provide distinct structural conformations around the bond, empowering them as ideal systems for studying the rotation ...

Mesoscopic Model for Diffusion-Influenced Reaction Dynamics

, 2003
A hybrid mesoscopic multi-particle collision model is used to study diffusion-influenced reaction kinetics. The mesoscopic particle dynamics conserves mass, momentum and energy so that hydrodynamic effects are fully taken into account.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only
