| 1 | Molecular design, synthesis strategies and recent advances of hydrogels for wound dressing applications显示文摘With the changes in the modern disease spectrum,pressure ulcers,diabetic feet,and vascular-derived diseases caused refractory wounds is increasing rapidly.The development of wound dressings has partly improved the effect of wound management.However,traditional wound dressings can only cover the wound and block bacteria,but are generally powerless to recurrent wound infection and tissue healing.There is an urgent need to develop a new type of wound dressing with comprehensive performance to achieve multiple effects such as protecting the wound site from the external environment,absorbing wound exudate,anti-inflammatory,antibacterial,and accelerating wound healing process.Hydrogel wound dressings have the aforementioned characteristics,and can keep the wound in a moist environment because of the high water content,which is an ideal choice for wound treatment.This review introduces the wound healing process and the development and performance advantages of hydrogel wound dressings.The choice of different preparation materials gives the particularities of different hydrogel wound dressings.It also systematically explains the main physical and chemical crosslinking methods for hydrogel synthesis.Besides,in-depth discussion of four typical hydrogel wound dressings including double network hydrogels,nanocomposite hydrogels,drug-loaded hydrogels and smart hydrogels fully demonstrates the feasibility of developing hydrogels as wound dressing products and their future development trends. | Dan Zeng Shihong Shen Daidi Fan | 2021 | Chinese Journal of Chemical Engineering2021，34，2： | 3 |
| 2 | Enhanced Bamboo Reinforced Aluminum Laminates显示文摘A new technique has been developed for flattening circular natural bamboo culm to plate form for remarkably enhancing its mechanical properties, The enhanced bamboo, cheaper than Al, is then used to reinforce an aluminum alloy for civilian applications. The properties of the composite are greatly enhanced compared to those of the Al alloy. The Al protects bamboo from bioerosion and improves | Shihong LI Shaoyun FU and Benlian ZHOU (Int.

| 3 | A Biomimetic Model of Fiber-reinforced Composite Materials显示文摘In thjs paper. bamboo fiber has been. on micro scale. investigated as a helical. multi-layered hollow cylinder, the stiffness featu res of bamboo bast fiber were compared with those of a multifilament yarn in traditional fiber-reinforced composite materials, Moreover. a biomimetic model of the reinforce ment of fiber-reinforced composite materials was proposed by imitating the fine structure of bamboo bast fiber. The results show that the comprehensive stiffness properties of the cornplicated fine struc ture of bamboo fiber is superior over those of traditional fiber-reinforced composites. | Shihong LI Ronghui ZHANG Shaoyun FU Xin CHEN and Benlian ZHOU(Institute of Metal Research, Academia Sinica, Shenyang, 110015, China)Qiyun ZENG(Institute of Applied Ecology, Academia Sinica, Shenyang, 110015, China) | 1994 | Journal of Materials Science & Technology1994，10，1： | 0 |
| 4 | The Equalization Gap of Basic Public Services Supply in China:An Empirical Study on Education,Health Care and Social Security显示文摘The equalization of basic public services which helps to meet people’s ever-growing needs for a better life is an important component of the supply-side structural reform under the new normal.This paper constructs the mechanism model and index of basic public services equalization,measures the equalization of education,health care and social security in China during the period of 2005-2016,and empirically tests the contributory factors with regional panel data.It is found that the equalization of basic public services has not been significantly improved by the last 12 years of urbanization;people tend to seek high-end consumption beyond basic public services with the increasing per capita disposable income;while the population structure and the gap between urban and rural areas constitute the main impediments,local governments’revenues and fiscal efficiency can significantly improve the equalization of basic public services.Therefore,the key to the supply-side structural reform of public services lies in enhancing the matching capability of public services in urbanization,reducing the consumption gap between urban and rural public services,and improving the efficiency of government’s public services expenditure. | Shihong Zeng Fei Xia Peng Yang | 2018 | China Finance and Economic Review2018，7，3： | 0 |
| 5 | Why rapid urbanization can’t improve employment absorption capacity of service industry in China:reflections on innovating the model of interaction between service industry development and urbanization under economic transformation and upgrading显示文摘Mathematical models show that the urbanization process is an important factor affecting the transfer of labor among economic sectors.The regression results using time-series data since China’s reform and opening up show that there is significant positive correlation between urbanization and the service industry’s ability to create jobs.However,there is no Granger Causation between them.Therefore,China should shift from focusing on industry park construction to paying more attention to improving urban functions by increasing their employment density of urban services. | Zeng Shihong Xia Jiechang | 2016 | China Finance and Economic Review2016，5，2： | 0 |
