Ultrafast and stable phase transition realized in MoTe-based memristive devices.

Phase engineering of two-dimensional transition metal dichalcogenides has received increasing attention in recent years due to its atomically thin nature and polymorphism. Here, we first realize an electric-field-induced controllable phase transition between semiconducting 2H and metallic 1T' phases in MoTe memristive devices. The device performs stable bipolar resistive switching with a cycling endurance of over 10, an excellent retention characteristic of over 10 s at an elevated temperature of 85 °C and an ultrafast switching of ∼5 ns for SET and ∼10 ns for RESET.

[Distribution of Typical Pollutants from Rainwater Sewer Sediments in Suzhou City].

In this study, we separately collected rainwater sewer sediments from typical samples in Suzhou city, such as the urban commercial district, historical and cultural protection area, cultural and educational area, and living area, and analyzed the particle size distribution of the sediments and the characteristics of carbon, nitrogen, phosphorus content, and pollution load distribution under each graded particle size. The median particle size of each sample point was 16.55-327.

[Effect of tianma gouteng decoction on the endothelial function and the renal protein expression in spontaneously hypertensive rats].

Ojective: To observe the effect of tianma gouteng decoction (TGD) on the endothelial function and the renal protein expression of spontaneously hypertensive rats, and to analyze its possible mechanism.

Methods: Totally 18 6-week-old SHR were randomly divided into 3 groups according to randomized block design, the SHR control group, the TGD group, and the captopril group, 6 in each group. Meanwhile, Wistar Kyoto (WKY) rats of the same age were recruited as a WKY control group.

[Analysis of renal protein expressions of spontaneously hypertensive rat intervention by three different Chinese medicine compounds for hypertension].

Objective: To observe the differential protein expression profile of three different Chinese medicine compounds on spontaneous hypertensive rat, which were Banxiabaizhutianma Decoction, Dihuangyinzi Decoction and Tianmagouteng Decoction, and to elaborate their function characters and regulation pathway using the principal component analysis and analyze the basic theory of different treatment of hypertension.

Methods: Give three compounds to 6-week-old SHR (Spontaneous hypertensive rat) as experimental group and captopril to 6-week-old WKY (Wistar-Kyoto rat) as control group by gavage. Monitor the blood pressure of rat tail to 24-week-old and then all rats were decapitated.
