MnO2/polyaniline/graphene composite as a supercapacitor electrode material was synthesized through an interfacial polymerization approach in the interface of oil/water phase. The as-synthesized MPG is characterized by infrared spectroscopy, XRD, XPS, SEM and TEM, and its electrochemical performance is measured by cyclic voltammetry, galvanostatic charge/discharge, and electrochemical impedance spectroscopy. The 3D nanostructure of MPG and loose nanorod structure of polyaniline (PANI) coated with round MnO2 pellets could be clearly observed. The maximum energy density of MPG is 45.4 Wh/kg (at a power density of 67.8 kW/kg) and the highest power density is 229.2 kW/kg (at an energy density of 25.7 Wh/kg). The capacitance retentions after 500 cycles at the scan rate of 5 mV/s for MGP composite and PANI/graphene are 70.4% and 59.1%, respectively, and the capacitance values after 500 cycles are 158.4 F/g and 114.8 F/g, respectively. The improved performance of MPG is due to the 3D nanostructure, loose nanorod structure of PANI and stable support of graphene, which prevent the mechanical deformation effectively during the fast charge/discharge process and facilitate the diffusion of the electrolyte ions into the inner region of active materials. The composite material is very promising for the next generation of high-performance supercapacitors electrode.

Precipitation plays an important role in the water supplies that support ecological restoration by sustaining large-scale artificial plantations in arid and semiarid regions, especially black locust(Robinia pseudoacacia) plantations(RP plantations), which are widely planted due to R. pseudoacacia being an excellent pioneer species. Characterizing the response of soil moisture to rainfall events at different stages of restoration is important for assessing the sustainability of restoration in RP plantations. In this study, we quantified the response of soil moisture to rainfall events at different years of restoration(15, 20 and 30 yr) representing different restoration stages in RP plantations in a typical hilly-gully area, i.e., the Yangjuangou Catchment, of the Loess Plateau, China. Over the growing season(June to September) of 2017, smart probes were placed at nine depths(10, 20, 40, 60, 80, 100, 120, 150, and 180 cm below the soil surface) to obtain volumetric soil water information at 30-min intervals in the three RP plantations. The advance of the wetting front was depicted, and the total cumulative water infiltration was measured. Soil moisture was mainly replenished by eight heavy rainfall events(mean rainfall amount = 46.3 mm), accounting for 88.7% of the rainfall during the growing season. The mean soil moisture content profiles of RP plantations at the three restoration stages were ordered as 30-yr(14.07%) > 20-yr(10.12%) > 15-yr(8.03%), and this relationship displayed temporal stability. Soil moisture was primarily replenished by rainfall at the 0-60 cm soil depth, and soil moisture remained stable below the 100-cm soil depth. The rainfall regime influenced the advancement of the wetting front. Here, a single rainfall event of 30 mm was the rainfall threshold for infiltration into the 60-cm soil layer. The total infiltration time ranged from 310.5-322.0 h, but no significant differences were found among RP plantations at different restoration stages. You

In this article a new receiving mode for scattering light by particle is theoretically discussed. Using this receiving mode the convex lens can be omitted during determining the extinction of particle. Therefore the extinction coefficient of sphere particles is redefined by extrapolating the conventional one. In terms of the calculation results of light scattering the definition of near-field extinction coefficient of a swarm particle is depicted. Through the error analysis it is proved that the error coming from the new definition of extinction coefficient is acceptable for engineering application. In addition, a technique for determining the particle size and density is presented in this article and the advantage using this receiving mode is described.

甘泉学派是中晚明与阳明心学分庭抗礼的存在。两家虽然学术宗旨相异,但并非泾渭分明。不论阳明后学还是甘泉后学中,一直有主张融通的声音。本文以甘泉后学中以往学界缺乏研究的蔡汝楠为例,通过对其“养中”与“格物”观念的分析,探讨其对于王、湛两家之学的融通。在蔡汝楠看来,其“中”与“养中”的观念可以消解“良知”与“天理”之间的紧张,使得本体的主观性与客观性得到统一;其“格物”观则可以将“致良知”和“随处体认天理”统一起来,避免双方之间的彼此攻讦。从本文的分析可以看到,蔡汝楠的“养中”和“格物”,正是颇能体现其自觉融通王、湛两家思想的观念。

Background Traditional Chinese medicine (TCM), especially herbal medicine, has been widely used in China and now is also being increasingly used in other countries for the treatment of cardiovascular diseases. Although many studies have demonstrated that certain Chinese herbal products are effective and safe for the treatment of cardiovascular diseases, most of these lack sufficient quality. Therefore, large randomized clinical trials and further scientific research to determine its safety, effectiveness are *** YiQi Dripping Pills (QSYQDP) is a herbal preparation clinically used in the treatment and prevention of coronary artery disease. Preliminary observations have shown its safety and effectiveness. Methods/Design This randomized, controlled trial will recruit 3600 patients with a history of myocardial infarction. Patients will be randomized into two groups by a Centr-Randomized System. One group receives QSYQDP, the other group receive aspirin. This trial protocol will describe eligibility criteria, detailed information on the treatment definition, blinding, endpoints, statistical methods, sample size determination, data management, legal aspects, and the current status of the trial. Discussion This trial is one of the first randomized, controlled clinical trial to evaluate the efficacy and safety of traditional Chinese herbal medicine in the treatment and secondary prevention of coronary artery disease. The results of this study should help to define the role of TCM in modern medical care, as well as to provide the management strategy for CAD patients in China and other countries.
