Alkyl-substituted tetra-coordinate organoboronium bisdiketone complexes exhibit dramatic luminescence thermochromism in organic solvents. In glass-forming alcohols, these complexes exhibit a reversible aqua blue to orange-red to greenish yellow luminescence emission colour change upon cooling.
Al2O3 changes from transparent to a range of intense colours depending on the chemical impurities present. In blue sapphire, Fe and Ti are incorporated; however, the chemical process that gives rise to the colour has long been debated. Atomistic modelling identifies charge transfer from Ti(III) to Fe(III) as being responsible for the characteristic blue appearance.
For decades, parties accused of patent infringement in district court litigation have relied upon the doctrine of inherent anticipation to attack the validity of patent claims. Generally, such inherency arguments are supported by testimony from an expert witness. Because America Invents Act reviews before the U.S. Patent and Trademark Office’s Patent Trial and Appeal Board allow parties to subm...
Crystals of C.I. Disperse Blue 354, a commercial methine disperse dye, were grown from an ethyl acetate and the crystal structure was determined. Results show that two aromatic planes are effectively coplanar with the dihedral angle of 10.61(11) degrees. The dicyanomethylene group is slightly twisted and two n-hexyl groups tend to be separated with one alkyl group being at the level of the arom...
Permanent photobleaching of blue luminescence with a maximum at ~390 nm in Ge-doped fiber preforms by exposure to the third harmonic (354 nm) of a Nd:YAG laser has been observed. The experimental results show that photodestruction of a germanium oxygen-deficient center can occur without photoionization.
In this work, we reported a systematic investigation on the interactions betweenmethylene blue (MB) and surface-confined DNA by using electrochemical methods. Wedemonstrated that the redox potential of MB and binding and dissociation kinetics of MB toDNA differed significantly for single-stranded DNA (ss-DNA) and double-stranded DNA(ds-DNA) immobilized on gold electrodes. This was possibly due ...
The title compound, C(18)H(17)N(3)S(2), was synthesized by the reaction of 5-(3,5-dimethyl-phen-yl)-1,3,4-thia-diazol-2-amine and 4-(methyl-sulfan-yl)benzaldehyde. An intra-molecular C-H⋯S hydrogen bond results in the formation of a planar (r.m.s. deviation = 0.003 Å) five-membered ring. In the crystal structure, inter-molecular C-H⋯N hydrogen bonds link the mol-ecules to form layers parallel t...
A description is given of the light-injection calibration system that has been developed for the MINOS long-baseline neutrino oscillation experiment. The system is based upon pulsed blue LEDs monitored by PIN photodiodes. It is designed to measure non-linearities in the PMT gain curves, as well as monitoring any drifts in PMT gain, at the 1% level.
The flexibility of insect adhesive pads is crucial for their ability to attach on rough surfaces. Here, we used transparent substrates with micropillars to test in adult cockroaches (Nauphoeta cinerea) whether and how the stiffness of smooth adhesive pads changes when shear forces are applied, and whether the insect's age has any influence. We found that during pulls towards the body, the pad's...
Reaching neutral territory: The title compound, the first tetrasubstituted deltahedral Zintl cluster, is no longer an ion (see picture; Ge green, Si purple, Sn blue). It is a neutral molecule formed by a reaction of the trisilylated anion with Ph(3) SnCl.
