Silicon （Si） has been considered as one of the most promising anode material for tHe next generation lithium-ion batteries （LIBs） with high energy densities, due to its high theoretical capacity, abundant availability and environmental friendliness. However. silicon materials with low intrinsic electric and ionic conductivity suffer from huge volume variation during lithiation/delithiation processes leading to the pulverization of Si and subsequently resulting in severe capacity fading of the electrodes. Coupling of Si with carbon （C） realizes a favorable combination of the two materials properties, such as high lithiation capacity of Si and excellent mechanical and conductive properties of C. making silicon/carbon composite （Si/C） ideal candidates for LIBs anodes. In this review, recent progresses of Si/C materials utilized in LIBs are summarized in terms of structural design principles, material synthesis methods, morphological characteristics and electrochemical performances by highlighting the material structures. The mechanisms behind the performance enhancement are also discussed. Moreover, other factors that affect the performance of Si/C anodes, such as prelithiation, electrolyte additives, and binders, are also discussed. We aim to present a full scope of the Si/C-based anodes, and help understand and design future structures of Si/C anodes in LIBs,

This study aimed to solve the issues in safe wintering of alfalfa in the north of China. The^(60)Co-γ rays, ultraviolet and EMS were used to mutagenize seeds of 4 cultivars of alfalfa to investigate the effects of mutagens on antioxidant enzymes activity and cold resistance of alfalfa. The results showed that after the mutagenic treatment, the activity of the three kinds of antioxidant enzymes basically showed upward trends.^(60)Co-γ radiation increased the activity of SOD; ultraviolet radiation decreased the activity of SOD; and low-concentration EMS promoted and high-concentration EMS inhibited the activity of SOD. The activity of POD and CAT decreased with the increased radiation dose of^(60)Co-γ, but increased with the increased radiation dose of ultraviolet. The effects of EMS treatment on the activity of POD and CAT differed among different alfalfa cultivars. The concentration of MDA reduced under 30-min, 60-min ultraviolet treatment and 0.4% EMS treatment. According to the subordinate function values of various indices, it could be concluded that 150 Gy of^(60)Co-γ radiation, 90 min of ultraviolet radiation, and 0.4% of EMS were more conducive to improving the cold resistance of alfalfa. This study will provide a theoretical basis for the research on adaptability and cold resistance of alfalfa in rigid cold region and a technical reference for the breeding of high-yield, highquality and cold-resistant alfalfa cultivars.

On the Changbai Mountain Nature Reserve (established in 1960) in Northeast China there lies some pure land unspoiled by human activity. This is an invaluable heritage left by our ancestors. Yet in our generation human interference is threatening its purity. When I climbed up the mountain in 1975 for the first time, I was fascinated by the profusion of flowers of all colours, luxuriant forests and large tracts of green meadows. From that moment on, these pictures were vividly engraved in my memory, and they often appear in my dreams. Now, almost twenty years have passed, in which mass tourism has been developing at a fast pace. Is my dream mountain still as charming as it was before? What

In order to better control common diseases of corn and soybean in Sanjiang plain,the in vitro antifungal activity of corydalis chloroform extract against several common fungal diseases of corn and soybeans was tested using mycelial growth rate method. The test result of mycelial growth rate showed that the inhibition rate of corydalis chloroform extract against Cercosporidium sofinum（ Hara） Liu ＆ Guo and Rhizoctonia solani Kuhn were all above 80%,and EC50 values were52. 98- 58. 98 mg /L. The test result of spore germination showed that the inhibition rates against spore germination of all pathogenic fungi were high,in which the inhibition rates against spore germination of C. sofinum and Bipolaris maydis reached 100%. Biological control test showed that the control effects against other diseases were below 60% except that against R. solani reaching 61. 46%.

TRICHOSANTHIN (TCS) is a type Ⅰ ribosome inactivating protein (RIP) with the N-glycosi-dase activity. It removes adenine (ADE) at position A4324 of 28SrRNA. The crystal struc-tural model and the activity of mutants show that the cleft between two domains is the activitypocket of the N-glycosidase. This provides a solid foundation for the study on relationship be-tween structure and function. Several crystal structures of the complex for exploring the mech-anism of the N-glycosidase have been reported, including TCS/FMP and TCS/ANE complex-es by Yang et al., TCS/NADPH complex by Xiong et al., α MMC/FMP and αMMC/ADE complexes by Ren et al., RTA/FMP and RTA/ApG complexes by Monzingo
