Biodegradable polymers like PLA and PCL have wide application in tissue engineering because of their biocompatibility, degradation and mechanical properties. In this study, the optimised electrospinning parameters of PLA/PCL composite membranes were determined with scanning electron microscopy to obtain smooth and relatively fine microfibre. The properties and structure of electrospinning PLA, PCL and PLA/PCL(70/30) membranes were investigated by scanning electron microscopy (SEM), differential scanning calorimetry (DSC), X-ray diffraction (XRD), the water contact angle, water absorption degree and tensile strength. The results revealed that PLA/PCL composite membranes possessed better mechanical and hydrophilic properties when compared to single component microfibre membranes like PLA and PCL. The improvements above are conducive to microfibre membrane application in the biomedical sector.

To reveal the spatial differentiation characteristics of rural multifunctionality in Chinese county areas and quantitatively identify the influencing factors of spatial differentiation of rural multifunctionality, this study comprehensively evaluated rural multifunctionality at the county level in China from 2000 to 2015 by constructing an evaluation index system, using entropy weight method, semi-variance function, and geodetector method. The main results are as follows: 1) The spatial distribution of rural multifunctionality was uneven. Highvalue regions of rural multifunctionality were concentrated in the plain areas and the eastern coasts of China. Low-value regions were concentrated on the plateaus and in the mountain regions. Rural multifunctionality presents a gradual upward temporal trend as a whole. 2) The contribution rate of economic development function and social security function to rural multifunctionality gradually increased, and the contribution rate of agricultural production function and ecological conservation function to rural multifunctionality gradually decreased. 3) From 2000 to 2015, the range and intensity of spatial auto-correlation of rural multifunctionality gradually decreased at the county level in China. Random factors became the driving forces of spatial differentiation of rural multifunctionality. 4) Economic development and fiscal revenue of counties were the main factors that affect the spatial differentiation of rural multifunctionality. The interaction of different influencing factors enhanced the spatial differentiation of rural multifunctionality. The degree of influence of social factors was gradually rising and the degree of influence of natural factors was gradually decreasing over time.

Our results suggest that TGFBR2 and miR-518 harbor variants that increase the risk of EH and affect blood pressure homeostasis as well as efficacy of antihypertensive agents.

Synergistic effect of Se-deficiency and CuI-doping significantly enhances the thermoelectric figure-of-merit of the n-type polycrystalline In4Se3-based materials via improving the power factor. With In4Se2.95(CuI)0.01, ZT = 1.34 at 723 K, the highest value obtained for Pb-free polycrystalline In4Se3-based materials to date.
