Journal ArticleDOI
Photodissociation of Hydrated Hydrogen Iodide Clusters
TL;DR: This study shows how the hydrogen and halogen radicals are dissociated and released from their hydrated acids and predicts the predicted mechanism for the release of hydrogen molecules from iodic acid in water by ultraviolet light.
Journal ArticleDOI
Highly Efficient Pure‐Blue Perovskite Light‐Emitting Diode Leveraging CsPbBrxCl3−x/Cs4PbBrxCl6−x Nanocomposite Emissive Layer with Shallow Valence Band

TL;DR: In this paper , a pure-blue metal-halide perovskite light-emitting diodes (PeLEDs) was demonstrated by leveraging a novel CsPbBrxCl3•x/Cs4Pb•Cl6•x nanocomposite film as an emissive layer, leading to high luminescence efficiency due to significant reduction of nonradiative recombination.
Journal ArticleDOI
Coarse and fine-tuning of lasing transverse electromagnetic modes in coupled all-inorganic perovskite quantum dots
Youngsin Park,Guanhua Ying,Atanu Jana,Vitaly Osokin,Claudius Kocher,Tristan Farrow,Tristan Farrow,Robert A. Taylor,Kwang S. Kim +8 more
TL;DR: In this paper, the authors demonstrate the direct observation of lasing from transverse electromagnetic (TEM) modes with a long coherence time ∼ 9.5 ps in coupled CsPbBr3 quantum dots, which dispense with an external cavity resonator.
Journal ArticleDOI
Halides with Fifteen Aliphatic C–H···Anion Interaction Sites

TL;DR: X-ray structures of organic crystals that feature a chloride anion bound exclusively by hydrophobic Cali–H groups are reported and it is noted that such types of complexes may not be rare since such high numbers of binding sites for an anion are also found in analogous tetraalkylammonium complexes.
Book ChapterDOI
Computing technologies, theories, and algorithms. The making of 40 years and more of theoretical and computational chemistry
TL;DR: The point in time where ab initio electronic structure calculations were first beginning to be carried out is roughly 40 years ago, and since that time, all parts of theoretical chemistry have developed links to computation.
