Tunable Optical Display of Multilayer Graphene through Lithium Intercalation.

The tunable optical display is vital for many application fields in telecommunications, sensors, and military devices. However, most optical materials have a strong wavelength dependence, which limits their spectral operation range. In this work, we develop an electrically reconfigurable optical medium based on graphene, demonstrating a cycle-controlled display covering the electromagnetic spectrum from the visible to the infrared wavelength.

[Clinical research on children mental retardation treated with acupuncture].

Objective: To observe the impacts of acupuncture on intelligent structure, social adaptability and fMRI brain function in children mental retardation (MR).

Methods: Sixty cases of MR in compliance with the diagnostic standard were randomized into an acupuncture group and a medication group, 30 cases in each one. In the acupuncture group, Sishenzhen [four points, 1.
