Photochemistry of the PAH pyrene in water ice: the case for ion-mediated solid-state astrochemistry

, 2009
Context. Icy dust grains play an important role in the formation of complex inter- and circumstellar molecules. Observational studies show that polycyclic aromatic hydrocarbons (PAHs) are abundantly present in the ISM in the gas phase.

Photochemistry and Photophysics of Coordination Compounds of the Main Group Metals [PDF]

, 1992
The photoproperties of main group metal complexes with the electron configurations s2 (e.g. T l + , Sb3 + , Te4 + ) and s° (e.g. T l 3 + , Pb4 + ) were studied on the basis of a general concept which relates characteristic excited states to typical ...

Topologically reconfigurable room-temperature polariton condensates from bound states in the continuum in organic metasurfaces

Nature Communications
An exciton–polariton condensate is a state of matter with collective coherence leading to many fascinating macroscopic quantum effects. Recently, optical bound states in the continuum (BICs) have been demonstrated as peculiar topological states capable ...

Doping-Promoted Solar Water Oxidation on Hematite Photoanodes

Molecules, 2016
As one of the most promising materials for solar water oxidation, hematite has attracted intense research interest for four decades. Despite their desirable optical band gap, stability and other attractive features, there are great challenges for the ...

Experimental investigations of diacetylene ice photochemistry in Titan's atmospheric conditions [PDF]

A&A, 684, A1 (2024)
A large fraction of the organic species produced photochemically in the atmosphere of Titan can condense to form ice particles in the stratosphere and in the troposphere. According to various studies, diacetylene (C$_4$H$_2$) condenses below 100 km where it can be exposed to ultraviolet radiation.

Extraterrestrial prebiotic molecules: photochemistry vs. radiation chemistry of interstellar ices.

Chemical Society Reviews, 2019
In 2016, unambiguous evidence for the presence of the amino acid glycine, an important prebiotic molecule, was deduced based on in situ mass-spectral studies of the coma surrounding cometary ice.

Photochemical synthesis of a “cage” compound in a microreactor: Rigorous comparison with a batch photoreactor [PDF]

, 2013
An intramolecular [2 + 2] photocycloaddition is performed in a microphotoreactor (0.81 mL) built by winding FEP tubing around a commercially available Pyrex immersion well in which a medium pressure mercury lamp is inserted.

Mechanistic insight into the competition between interfacial and bulk reactions in microdroplets through N2O5 ammonolysis and hydrolysis

Nature Communications
Reactive uptake of dinitrogen pentaoxide (N2O5) into aqueous aerosols is a major loss channel for NOx in the troposphere; however, a quantitative understanding of the uptake mechanism is lacking.
