The present work describes a new method to sense cholinesterase-catalyzed hydrolysis of acetylcholine (ACh) through a luminescence response of the hexarhenium cluster complex [{Re6S8}(OH)6](4-). A proton released from acetylcholinesterase (AChE)- or butyrylcholinesterase (BuChE)-catalyzed hydrolysis of ACh results in time-resolved...

Detuning-Controlled Internal Oscillations in an Exciton-Polariton Condensate.

Physical review letters

Voronova NS, Elistratov AA, Lozovik YE.
PMID: 26565479
Phys Rev Lett. 2015 Oct 30;115(18):186402. doi: 10.1103/PhysRevLett.115.186402. Epub 2015 Oct 27.

We theoretically analyze exciton-photon oscillatory dynamics within a homogenous polariton gas in the presence of energy detuning between the cavity and quantum well modes. Whereas pure Rabi oscillations consist of the particle exchange between the photon and exciton states...

The use of water-soluble calixarenes: p-sulfonato thiacalixarene (ST), tetra-sulfonatomethylated calix[4]resorcinarene (SR), calix[4]resorcinarene phosphonic acid (PhR) as chelating agents in cloud point extraction (CPE) of La(III), Gd(III) and Yb(III) ions using Triton X-100 as non-ionic surfactant is introduced. The data...

Here we report the clouding phenomenon, conductivity, (1)H NMR spectroscopy and dynamic light scattering data of mixed sodium dodecylsulfate-calix[4]resorcinarene micellar solutions in combination with tetrabutyl-, tetraethyl-, tetramethylammonium bromides and choline chloride. The NMR data reveal tight (the binding constant...
