XABS2: an empirical absorption correction program
The XABS2 Fortran program calculates an empirical absorption correction based on minimization of the 2 differences between F2obs and F2calc. The basic algorithm has been used in the crystallography…
An S = 6 cyanide-bridged octanuclear FeIII4NiII4 complex that exhibits slow relaxation of the magnetization.
Ac susceptibility and mu-SQUID measurements suggest that fast magnetization relaxation is present in zero-field due to quantum tunneling of the ground spin state (QTM) while application of small magnetic fields induces slow relaxation of the magnetization.

The synthesis of selected PCB metabolites with differing degrees of chlorination on the oxygenated phenyl ring is described, including chlorinated o-hydroquinones and 6-chloro-biphenyl-3,4-diol, which readily react with oxygen or via comproportionation to yield the corresponding semiquinone free radicals as detected by electron paramagnetic resonance spectroscopy (EPR alias ESR).

The bromopentacenes could be further elucidated to pentacene nitriles, further decreasing the acene's reduction potential, while the charge-carrier mobility in the fluorinated systems was shown to scale with the degree of fluorine substitution.
High current density, long duration cycling of soluble organic active species for non-aqueous redox flow batteries
Non-aqueous redox flow batteries (NAqRFBs) employing redox-active organic molecules show promise to meet requirements for grid energy storage. Here, we combine the rational design of organic…
Tetracene derivatives as potential red emitters for organic LEDs.
Simple light-emitting diodes fabricated from a series of functionalized tetracene derivatives showed that one of the derivatives did exhibit red electroluminescence.
