Ni-Doped BiVO4 with V4+ Species and Oxygen Vacancies for Efficient Photoelectrochemical Water Splitting

Bismuth vanadate is a promising photoanode material for photoelectrochemical(PEC)water splitting,but its activity and stability need to be further improved.In this work,we synthesized Ni-doped BiVO _(4 )abundant with V ~(4+)species and oxygen defects through an in situ electrodeposition method.The effective doping can decrease the particle size of BiVO _(4 )and lead to the formation of V ~(4+)species/oxygen defects.Accordingly,the doped and defective BiVO _(4 )showed high optical absorption and rapid charge transfer,and further showed much higher PEC activity than pure BiVO _4.Specifically,5-Ni-BiVO _(4 )exhibits the highest activity in PEC water splitting,with a photocurrent of 2.39 mA/cm ~(2 )at 1.23 V versus RHE(the reversible hydrogen electrode),which is 2.5 times higher than pure BiVO _4(0.94 m A/cm ~2),and much higher incident photon-to-current efficiency(IPCE)value of 45%(while only 25%for BiVO _(4 )at ca.400 nm).This work provides an in situ method for the development of a high-performance photoanode.

从雅俗互动看当代文学格局的变迁

通俗文学与严肃文学的关系是近年学术界研究的一个热点,它引发了对于雅俗文学界限、内涵、价值和评价体系的重新思考.传统的"雅俗对立"观在理论批评、创作实践、语境转换等方面都呈现出明显的不足.摒弃扬雅抑俗的传统观念,以互动共生的整体观来考察文学系统,是当代文学格局的必然性变动.     

产品伤害危机对品牌绩效指标的影响研究——基于随机模型方法的实证分析

准确评估产品伤害危机对品牌绩效指标的影响是企业进行产品伤害危机管理的前提。本文在对产品伤害危机及品牌绩效测量等相关理论文献回顾的基础上,通过建立NBD-DM随机模型,提供了一种评估产品伤害危机对企业品牌绩效影响的模型方法,并利用一组奶粉品类销售的固定样本组数据以雀巢奶粉碘超标事件为分析对象对该模型方法进行了实证分析。结果表明NBD-DM随机模型是动态测量品牌绩效的有效模型方法,并且证实产品伤害危机对品牌绩效指标的影响短期主要在于对品牌购买频率及其品牌品类需求份额的显著负向影响,而从长期来看,危机将改变NBD-DM模型所描述的稳定市场结构,从而对品牌绩效产生全面负向影响。最后讨论了结论对产品伤害危机管理的实践意义。

Exploring cultural differences in critical thinking: Is it about my thinking style or the language I speak?

Critical thinking is deemed as an ideal in academic settings, but cultural differences in critical thinking performance between Asian and Western students have been reported in the international education literature. We examined explanations for the observed differences in critical thinking between Asian and New Zealand (NZ) European students, and tested hypotheses derived from research in international education and cultural psychology. The results showed that NZ European students performed better on two objective measures of critical thinking skills than Asian students. English proficiency, but not dialectical thinking style, could at least partially if not fully explain these differences. This finding holds with both self-report (Study 1) and objectively measured (Study 2a) English proficiency. The results also indicated that Asian students tended to rely more on dialectical thinking to solve critical thinking problems than their Western counterparts. In a follow-up data analysis, students' critical thinking was found to predict their academic performance after controlling for the effects of English proficiency and general intellectual ability, but the relationship does not vary as a function of students' cultural backgrounds or cultural adoption (Study 2b). Altogether, these findings contribute to our understanding of the influence of culture on critical thinking in international education.
