Siloxane-Based Organosilicon Materials in Electrochemical Energy Storage Devices.

Siloxane-based molecular material, by virtue of its unique chemical structure, thermal and electrochemical properties, has triggered tremendous research interest and sparked a revolution for energy storage in the past years. Siloxanes and their analogues are generally demonstrated to be more environmentally friendly, durable, and safer when employed to reconstruct the nano-micro surface structure of electrodes, separators, and their interfaces with electrolytes. To better understand the recent and comprehensive achievement of siloxane-based materials in energy storage, a systematic summary is necessary to provide important clues, aiming at achieving better electrochemical properties.

Build a Rigid-Flexible Graphene/Silicone Interface by Embedding SiO for Adhesive Application.

An effective strategy was developed to enhance the adaptability of graphene/silicone matrices under external stimuli by embedding nanoscale SiO into the graphene/silicone interfaces as a buffer layer. Chemically reduced graphene (rGE) was first covered by SiO using an in situ preparation, forming sandwichlike rGE/SiO (rGES). Then, rGES was integrated into methyl vinyl polysiloxane, followed by vulcanization, producing the final rGES/silicone rubber (SR) nanocomposite.

A nanostructured graphene/polyaniline hybrid material for supercapacitors.

A flexible graphene/polyaniline hybrid material as a supercapacitor electrode was synthesized by an in situ polymerization-reduction/dedoping-redoping process. This product was first prepared in an ethylene glycol medium, then treated with hot sodium hydroxide solution to obtain the reduced graphene oxide/polyaniline hybrid material. Sodium hydroxide also acted as a dedoping reagent for polyaniline in the composite.

Effect of graphene oxide on the properties of its composite with polyaniline.

Graphene oxide, a single layer of graphite oxide (GO), has been used to prepare graphene oxide/polyaniline (PANI) composite with improved electrochemical performance as supercapacitor electrode by in situ polymerization using a mild oxidant. The composites are synthesized under different mass ratios, using graphite as start material with two sizes: 12 500 and 500 mesh. The result shows that the morphology of the prepared composites is influenced dramatically by the different mass ratios.

[Multi-central randomized controlled investigation on the massage for supplementing qi and removing obstruction in the Governor Vessel for treatment of infantile diarrhea due to spleen deficiency].

Objective: To make multi-central clinical evaluation of the massage for supplementing qi and removing obstruction in the Governor Vessel for treatment of infantile diarrhea due to spleen deficiency.

Methods: By using multi-central, randomized and controlled method, 275 cases were randomly divided into an observation group (n = 137) and a control group (n = 138). The observation group were treated by the massage for supplementing qi and removing obstruction in the Governor Vessel, and the control group by routine massage therapy in Tuina Science, a teaching material for college and school of TCM.
