Unusual behavior of thermal lens in alcohols.
We use a femtosecond pump-probe Z-scan technique to measure the thermal lens (TL) signal in a homologous series of primary alcohols. The trend in these experimentally measured TL signals deviates in a counterintuitive manner from the ones calculated using theoretical models that are only based on the macroscopic parameters. Introspection shows that the present TL theories are based on heat cond...
متن کاملA face-sharing bi-icosahedral model for Al₂₃⁻.
A face-sharing bi-icosahedral motif is proposed as a candidate structure of the magic cluster, Al23(-), on the basis of DFT calculations. The structure can be viewed as a quasi-molecule made of two Al13 (D3d) superatoms with an open electronic configuration via constructive overlap of 1F and 2P superatomic orbitals. A face-sharing tri-icosahedral motif is also predicted for Al33(-).
متن کاملA journey through ternary lead chlorido tungstates by thermal scanning.
The reduction of tungsten hexachloride with lead powder was investigated by differential scanning calorimetry (DSC) combined with X-ray diffraction (XRD) studies. Intermediate compounds along the way of the reduction of W6+ to W2+ were detected, prepared by solid-state synthesis, and structurally characterized by X-ray diffraction techniques. Five new compounds, namely Pb0.5WCl6, PbW2Cl10, Pb1....
متن کاملDistinct thermal behavior of GeO2 glass in tetrahedral, intermediate, and octahedral forms.
One fascinating high-pressure behavior of tetrahedral glasses and melts is the local coordination change with increasing pressure, which provides a structural basis for understanding numerous anomalies in their high-pressure properties. Because the coordination change is often not retained upon decompression, studies must be conducted in situ. Previous in situ studies have revealed that the sho...
متن کاملSynthesis of an unusual dinuclear chiral iron complex and its application in asymmetric hydrophosphorylation of aldehydes.
An unusual dinuclear chiral iron complex has been synthesized and effectively utilized in the asymmetric hydrophosphorylation of aldehydes to synthesize optically active α-hydroxy phosphonates with excellent yield and good enantioselectivity.
