Colloidal suspensions of glutaraldehyde （GA） crosslinked or grafted graphene oxide （GO） sheets were fabricated by simply tailoring the feed sequence. The different structures were confirmed by Fourier transform infrared spectra and X-ray diffraction. As demonstration of the utilities, the different colloidal suspensions were used to prepare free-standing papers by flow-directed filtration and poly（vinyl alcohol）（PVA）-based nanocomposite films by casting. Free-standing papers from GA crosslinked GO sheets exhibited better mechanical properties than unmodified GO paper, while nanocomposite films from GA grafted GO exhibit higher tensile strength and Young＇s modulus.

天然产物具有良好的生物相容性和环境友好性,研究此类非典型发光化合物对发光机理的理解以及绿色环保型发光材料的开发具有重要意义.基于此,本文研究了天然产物葡聚糖的光致发光性质与发光机理.结果表明,葡聚糖发光具有浓度增强、激发波长依赖性、分子量依赖性及聚集诱导发光等特性,其浓溶液在低温下表现出明显的激发波长依赖性的余辉,并且高分子量葡聚糖粉末还具有超长寿命室温磷光(p-RTP)发射.这些现象可用簇聚诱导发光(CTE)机理进行合理解释.随着葡聚糖浓度的增加或形成聚集体,氧原子簇聚形成不同的离域扩展的氧簇,其在O···O相互作用、氢键、分子链缠结等协同作用下构象刚硬化,因此能够受激发射.经压片后,葡聚糖片呈现更明显的长余辉,这是由于压片后分子堆积更为紧密,分子间相互作用增强,从而减少了分子运动引起的非辐射跃迁及空气中氧气和水分子对三线态激子的猝灭.

Mobile news apps have emerged as a significant means for learning about latest news and trends. However, in light of numerous news apps and information overload, motivating users to adopt one app is a major concern for both the industry and academia. Therefore, considering the attributes of mobile news and the debate on switching costs in the Internet context, based on the expectation-confirmation model (ECM), this study suggests that switching costs still exist and have a significant moderating effect on user satisfaction and continuous usage of mobile news apps. Furthermore, the different influences of information quality, system quality and service quality on continuance intention, user satisfaction and switching costs are discussed, showing that quality of information has a significant impact on users’ continuous usage of mobile news apps through increasing perceived usefulness, whereas personalized service quality have stronger effects through increasing user satisfaction and switching costs.

Gold-catalyzed nucleophilic addition to terminal alkynes has received considerable interest in the past decade, as this chemistry offers a highly efficient and regioselective way for CAC, CAH and CAX bond formation. However, such a nucleophilic addition mainly involves a Markovnikov addition. In this short review, the recent progress of the gold-catalyzed 5-endo-dig cycloisomerization-initiated tandem reactions by utilizing the steric strain in ring formation to achieve an anti-Markovnikov regioselectivity was reviewed, including the scope of reactions, mechanism and synthetic applications.
