The effects of carbon nanomaterials on the kinetics of gas hydrate formation are reviewed in de- tail. The influence of parameters such as growth cycle is introduced. The effects of the concentration of nanomaterials on the kinetics of hydrate production and the separation of CO2 in the gas mixture were a nalyzed. For non-covalently modified nanomaterials, the effects of surfactant modification and polymer modification on the kinetics of hydrate formation were expounded. In terms of covalent modification, the stability of the nanomaterials after redox modification and nano-metal ion modification and the formation characteristics of hydrate were analyzed. It is suggested that the key problem of promoting the formation of hydrates by carbon nanomaterials at this stage should be broken through from the two aspects of the stable dispersion of synthetic nanomaterials and the recycling performance of synthetic materials.

Polycystic ovary syndrome (PCOS) is a common gynecological disease among women of reproductive age. It causes reproductive disorders and metabolic abnormalities, which has heterogeneous clinical manifestations. Hypothalamic inflammation is a low -grade inflammatory disease with microglial activation as the main pathological change, which is considered as the pathological and physiological basis of PCOS metabolism, reproduction and clinical heterogeneity. Recent researches have clarified the crucial role of the hypothalamus in regulating and maintaining metabolic homeostasis and reproductive function. Through the induction pathway of hypothalamic inflammation, it is proposed that the common excessive intake of carbohydrates and saturated fatty acids is the main inducement. Furthermore, the important role of hypothalamic inflammation in the occurrence and development of PCOS related metabolic and reproductive disorders and the potential inducing pathways were described, and the abnormal signal transduction among hypothalamic neurons and between the center and periphery were considered as the key pathways to induce PCOS related pathological changes. These pathways are expected to provide new ideas and targets for clinical treatment of PCOS. [ABSTRACT FROM AUTHOR]

Ultrasound strengthening technology has gained more and more attention in drying research, however, the strengthening mechanism of ultrasound on water status and moisture migration during drying has been unclear until now. In order to investigate the strengthening effect of contact ultrasound on moisture migration of pear slices during hot air drying process, the experiments of ultrasound reinforced hot air drying on pear slices were conducted with different ultrasound powers. The scan electric microscope was used to observe the surface microstructure of dried pear slices at different ultrasound powers. The low-field nuclear magnetic resonance (LF-NMR) technology and nuclear magnetic resonance imaging (MRI) technology were applied to analyze the influence of ultrasound power on internal water state and moisture migration of pear slices during hot air drying. The results showed that hot air drying of pear slices belongs to internal diffusion control, and the reduction ratios of drying time were 60.0%, 58.3% and 57.8% when contact ultrasound of 48 W was applied in hot air drying of pear slices at 35, 45 and 55 ℃, respectively, which indicated that the application of contact ultrasound could significantly accelerate drying process. The drying time reduced from 1440 min to 1260, 960, 780, 600 min when contact ultrasound assistance at 12, 24, 36, 48 W was applied in hot air drying of pear slices at 45 ℃, which showed that higher ultrasound power could lead to higher water removal rate and shorter drying time. The results of scan electric microscope showed that the application of ultrasound could improve the number of micro-capillaries as well as enlarge the size of micro-capillaries, and higher ultrasound power produced looser microstructure of pear surface that was contacted with ultrasound radiation board, which was favorable to moisture migration and water diffusion. The LF-NMR results showed that the peak amplitudes of inversion spectrum kept decreasing during the drying process and higher ultrasound power led to faster decreasing rate of the amplitudes, which represented that free water, immobilized water and bound water inside pear slices changed and migrated during drying process, and higher ultrasound power could accelerate the migration of the 3 kinds of water. Free water, with the greatest mobility and the highest content, was the first kind of water for total removal. The removal time of free water was 720, 660, 600, 480 and 360 min at ultrasound powers of 0, 12, 24, 36 and 48 W, respectively. Ultrasound showed great strengthening effect on free water removal, which indicated that ultrasound could achieve good energy transmission and strong water turbulence at the existence of free water. The contents of immobilized water and bound water decreased during the drying, however, the immobilized water and bound water inside pear slices could not be removed completely. The peak areas became smaller with the increase of ultrasound power, which indicated that the increase in ultrasound power could improve water mobility and reinforce moisture migration. The MRI results showed the change of moisture content and water distribution at different ultrasound powers during the drying process, and higher ultrasound power caused faster moisture reduction, which indicated that the MRI images could visually illustrate the change and transformation of water inside pear slices and the application of ultrasound could accelerate internal moisture migration significantly and increase drying rate. The research can present reference to the theoretical study and technical application of ultrasound enhanced hot-air drying technology. [ABSTRACT FROM AUTHOR]

Virtual simulation experimental teaching is the new direction and trend of economics experimental teaching reform. The construction of curriculum system of virtual simulation is the important content in virtual simulation experimental teaching field, and influences the training quality of the economic talents. Combined with the practice of Economics and Management Virtual Simulation Experimental Teaching Center, the paper explores and analyzes the construction of curriculum system for simulation of economies. According to the thinking of “ subjects orientation + specialty group guidance” , we construct the “020 coordination” virtual simulation course system of economics, in order to promote specialty coordination and improve teaching level.
