We synthesized B-He/B-GREDVY and immobilized them on avidin-coated *** examine the immobilization of molecules in the material, the following experiments were performed:fluorescein isothiocyanate(FITC) fluorescence staining, water contact angle and atomic force microscopy(AFM) measurements. Besides, the biological evaluation experiments were also performed, such as platelets adhesion and activation, the culturing of smooth muscle cells(SMC) and endothelial cells(EC). These experimental results show that the modified surfaces could prevent the hyperproliferation of SMC, and promote the proliferation and migration of EC and EPC. Furthermore, the adding of VEGF improved the EC adhesion in a dynamic environment. Generally, it is expected that the modified surfaces could be used to accelerate the formation of the newly endothelial layer for the construction of platforms for coronary artery stent therapy.

消费者是安全食品的需求方,其消费意愿能否有效转换为真实的购买行为很大程度上决定着安全食品的市场发展潜力与可持续性。基于对江苏和安徽两省12市984名消费者实地调研数据的实证分析表明,消费者对安全食品的支付行为偏差普遍存在,特别是在有购买意愿的消费群体中,意愿与行为间有较大差距;食品市场安全满意度与家庭年收入是偏差的重要成因,年龄、受教育程度、认证标识信任度、对安全认证食品的了解程度、购买渠道的便利性、购买条件等则在一定程度上抑制着偏差的形成。因此,政府需要加强对公众的食品安全知识宣传,提升居民对安全食品的了解程度与信任水平;生产商与销售商要进行积极的产品推广与渠道拓展,提高公众购买安全食品的便利性,同时优化安全食品的生产流程,降低营销成本,提升居民的购买能力。

中国是生猪生产与消费大国,居民对安全认证猪肉的购买意愿与支付行为对生猪产业发展与市场安全至关重要,对猪肉产业食品安全影响深远。由于消费者真实行为决策信息的收集成本较高,流程较为复杂,现有研究多基于消费者购买意愿的视角展开分析,以期为生产商、销售企业、政府等相关利益主体提供一定参考建议。然而,由于偏好认知的不确定性以及外部环境的干扰制约,消费者的意愿表达与现实选择间往往具有一定差距,对消费者购买意愿的研究由于支付行为偏差的存在在应用借鉴上具有一定局限性,因此,为深入了解消费者的支付行为偏差及其成因,促进农产品安全生产消费,本文基于对江苏和安徽两省12市844名消费者的实地调查数据,利用Probit模型进行了系统分析,结果显示:(1)消费者安全认证猪肉的支付行为偏差普遍存在,大多数有购买意愿的消费者实际上并未做出真实的支付行为,意愿与行为间具有较大的差距;(2)猪肉市场安全满意度与家庭年收入是出现偏差的重要原因,猪肉市场安全满意度与家庭年收入越高,消费者支付行为偏差出现的可能性就越大;(3)年龄、受教育程度、认证标识信任度、对安全认证猪肉的了解程度、购买渠道的便利性、购买条件等因素对偏差的形成具有负向抑制作用,能够有效促进消费者购买意愿转变成真实的支付行为。针对上述研究结论,为促进安全认证猪肉市场的发展,提升猪肉产品的质量水平,有力保障食品安全,本文提出如下政策建议:(1)加强对公众食品安全知识的普讲宣传,提升居民对安全认证猪肉的了解程度与信任水平;(2)进行积极的产品推广与渠道拓展,提高公众安全认证猪肉的购买便利性;(3)优化安全认证猪肉的生产流程,降低营销成本,提升居民的购买能力。

通过水热法和低温煅烧法分别合成了稳定的碳量子点(CQDs)和Ni_(12)P_(5),通过简单的机械研磨将两者复合成CQDs-Ni_(12)P_(5)。采用X射线衍射(XRD)、透射电镜(TEM)和电化学阻抗(EIS)等对催化剂进行了表征,并通过荧光光谱(FL)测试其电子转移行为。以染料Eosin Y(EY)为催化剂(敏化剂),Ni_(12)P_(5)为助催化剂,三甲胺(TMA)为牺牲剂,研究了CQDs修饰Ni_(12)P_(5)的染料敏化制氢性能。研究表明,CQDs负载量为15 wt%的Ni_(12)P_(5)(15CQDs-Ni_(12)P_(5))拥有最高的染料敏化制氢活性(3565μmol·h^(-1)·g^(-1)),是纯Ni_(12)P_(5)的3.36倍。活性的提高是因为EY、CQDs及Ni_(12)P_(5)之间有效的电子传递。此外,探讨了可能的析氢反应机理。
