CO Adsorption Dynamics during CO2 Electrolysis in Aprotic Organic Electrolytes

Carbon dioxide electrolysis (CO 2 E) in fully aprotic organic electrolytes primarily yields oxalate (C 2 O 4 2−), carbon monoxide (CO), and carbonate (CO 3 2−). To understand this system, we investigated the adsorption dynamics in the CO adsorption region ...

Can increasing the size and flexibility of a molecule reduce decoherence and prolong charge migration?

Jiri Vanicek, Alan Scheidegger

Coherent superposition of electronic states, created by ionizing a molecule, can initiate ultrafast dynamics of the electron density. Correlation between nuclear and electron motions, however, typically dissipates the electronic coherence in only a few fem ...

Enhanced abatement of phenolic compounds by chlorine in the presence of CuO: Absence of electrophilic aromatic substitution

Urs von Gunten

It has been demonstrated that chlorine predominately reacts with phenolic compounds through an electrophilic aromatic substitution, yielding chlorinated phenols. Previous studies showed that copper oxide (CuO), a water pipe corrosion product, can catalytic ...

Ion Spectroscopy Reveals Structural Difference for Proteins Microhydrated by Retention and Condensation of Water

Oleg Boyarkine, Andrei Zviagin

Protein ubiquitin in its +7 charge state microhydrated by 5 and 10 water molecules has been interrogated in the gas phase by cold ion UV/IR spectroscopy. The complexes were formed either by condensing water onto the unfolded bare proteins in a temperature- ...

Nanocavities for Molecular Optomechanics: Their Fundamental Description and Applications

Christophe Marcel Georges Galland

Vibrational Raman scattering-a process where light exchanges energy with a molecular vibration through inelastic scattering-is most fundamentally described in a quantum framework where both light and vibration are quantized. When the Raman scatterer is emb ...

Shaped Laser Pulses for Microsecond Time-Resolved Cryo-EM: Outrunning Crystallization during Flash Melting

Marcel Drabbels, Ulrich Lorenz, Constantin Richard Krüger, Nathan Junior Mowry

Water vitrifies if cooled at rates above 3 × 105 K/s. In contrast, when the resulting amorphous ice is flash heated, crystallization occurs even at a more than 10 times higher heating rate, as we have recently shown. This may present an issue for microseco ...
