Optimal optical Ferris wheel solitons in a nonlocal Rydberg medium.

We propose a scheme for the creation of stable optical Ferris wheel (OFW) solitons in a nonlocal Rydberg electromagnetically induced transparency (EIT) medium. Depending on a careful optimization of both the atomic density and the one-photon detuning, we obtain an appropriate nonlocal potential provided by the strong interatomic interaction in Rydberg states that can perfectly compensate for the diffraction of the probe OFW field. Numerical results show that the fidelity remains larger than 0.

Tunable cyano substituents in D-A conjugated polymers accessed direct arylation for photocatalytic hydrogen production.

2-Styrylthiophene-based donor-acceptor linear conjugated polymers with tunable cyano substituents are atom-economically obtained direct C-H arylation for platinum-free photocatalytic hydrogen production, affording a HER of up to 9.79 mmol h g.

[Inhibitory effects of sinapine on activity of acetylcholinesterase in cerebral homogenate and blood serum of rats].

Objective: The present study investigated the inhibitory effects of Chinese herb component sinapine on activity of acetylcholinesterase (AChE) in cerebral homogenate and blood serum of rats.

Method: AChE was prepared from cerebral homogenate and blood serum of rats, respectively. Acetylcholinesterase activity assay kit and Chromatometry were used to detect the AChE activity.
