An amorphous phosphorus/carbon nanocomposite demonstrates a reversible 3-Li storage capacity of 2355 mAh g(-1) with an excellent capacity retention of 90% over 100 cycles and a superior power capability with 62% of its capacity realizable at a very high rate of 8000 mA g(-1), possibly serving as a high capacity and high rate alternative anode for next-generation Li-ion batteries.

This paper introduces a kind of headrest, which can improve sleeping, based on the mindset EEG device platform. It can extract the information of brain waves on the human body during the sleep and shorten the time to fall asleep. This headrest can fluctuate according to the human brain's EEG curve characteristic value extraction hypnotized. By calling Android phone music player software and media library before broadcasting via headphone in terms of the bluetooth device, users enable to fall asleep quickly. Headrest design structure enhances the comfort of its usage. The headrest is available in a variety of occasions.

BCI technology as a widely used technique is gradually into daily life. Based on the study of this technique and taking advantage of MindSet extraction equipment of EEG which is available in the market, we design a portable sleep apnea monitoring tools which use MindSet as a platform, which has comfortable pillow structure. Monitoring equipment described in the text achieves real-time monitoring for apnea, also has an alarm function. Apnea syndrome on self-monitoring and alarm has better effects.
