Large-scale single-crystalline SnO2 nanocauliflowers were successfully synthesized using a hydrothermal growth method without any template. The samples were characterized by X-ray diffraction （XRD）, field-emission scanning electron microscopy （FE-SEM）, en- ergy-dispersive X-ray spectroscopy （EDS）, transmission electron microscopy （TEM）, and selected area electron diffraction （SAED）. FE-SEM images show that the as-grown SnO2 nanocauliflowers are constructed of tetragonal prisms with a width of 500-600 nm. XRD, EDS, and SAED results indicate that the as-grown SnO2 nanocauliflowers are single crystalline with the tetragonal rutile crystalline structure. The growth mechanism of SnO2 nanocauliflowers is also preliminarily discussed on the basis of different Sn（OH） 62- concentrations, and it is found that Sn（OH） 62- concentration plays an important role in determining the shape of the prepared SnO2. Room temperature photoluminescence was further carried out on SnO2 nanocauliflowers to investigate their optical properties. An intense blue luminescence centered at a wavelength of 424 nm is observed in the as-grown SnO2 nanocauliflowers.

Nano TiO2/Fe3O4 composite particles with different molar ratios of TiO2 to Fe3O4 were prepared via sol-gel method. X-ray diffraction, transmission electron microscopy, and vibration sample magnetometry were used to characterize the TiO2/Fe3O4 particles. The photocatalytic activity of the particles was tested by degrading methyl blue solution under UV illumination （254 nm）. The results indicate that with the content of TiO2 increasing, the photocatalytic activity of the composite particles enhances, while the magnetism of the particles decreases. When the molar ratio of TiO2 to Fe3O4 is about 8, both the photocatalytic activity and magnetism of the TiO2/Fe3O4 particles are relatively high, and their photocatalytic activity remains well after repeated use.

“羊毛党”利用网络商家标价错误恶意下单以攫取不正当利益,致使网络商家损失惨重甚至关张歇业,已经成为我国电子商务产业发展中的一大“顽疾”。面对“羊毛党”恶意下单行为,受制于现行法倾斜保护消费者权益的惯性理念、电子商务合同的特殊成立规则、商家“最终解释权”立法态度不明、违约或履约成本高昂等综合制约因素,网络商家常常被逼入绝境。基于《民法典》规范的体系化优势,通过发挥公平、诚信原则的权益矫正功能,合理解释网络合同成立规范,利用补充性解释填补意思表示漏洞,用足“有过失”制度的衡平机制,可以为标价错误网络商家合同权益的救济提供有效路径。

以云南滇红茶为试验材料,采用响应面法优化生物酶法探讨其茶多糖提取工艺。在复合酶添加量、复合酶种类、复合酶比值、酶解时间、酶解温度、料液比各因素的单因素试验基础上,以茶多糖提取率为响应值,通过Box-Behnken中心组合优化法优化提取工艺参数,选取提取时间、复合酶添加量和料液比构建三因素三水平响应面优化试验。结果表明,滇红茶多糖的最佳工艺条件:复合酶种类为果胶酶和纤维素酶(质量比2∶1),复合酶添加量为0.90%(以底物质量计算),提取时间为3.0 h,提取温度45℃,料液比为1∶20(g/mL)。该条件下茶多糖提取率为4.22%±0.17%,与模型预测相符,可用于复合酶法提取滇红茶多糖。
