Paving the road toward the use of β-Fe2O3 in solar water splitting: Raman identification,phase transformation and strategies for phase stabilization

Although β-Fe₂O₃ has a high theoretical solar-to-hydrogen efficiency because of its narrow band gap, the study of β-Fe₂O₃ photoanodes for water splitting is elusive as a result of their metastable nature. Raman identification of β-Fe₂O₃ is theoretically and experimentally investigated in this study for the first time, thus clarifying the debate about its Raman spectrum in the literature. Phase transformation of β-Fe₂O₃ to α-Fe₂O₃ was found to potentially take place under laser and electron irradiation as well as annealing. Herein, phase transformation of β-Fe₂O₃ to α-Fe₂O₃ was inhibited by introduction of Zr doping, and β-Fe₂O₃ was found to withstand a higher annealing temperature without any phase transformation. The solar water splitting photocurrent of the Zr-doped β-Fe₂O₃ photoanode was increased by 500% compared to that of the pure β-Fe₂O₃ photoanode. Additionally, Zr-doped β-Fe₂O₃ exhibited very good stability during the process of solar water splitting. These results indicate that by improving its thermal stability, metastable β-Fe₂O₃ film is a promising photoanode for solar water splitting.     

Olivine-norite rock detected by the lunar rover Yutu-2 likely crystallized from the SPA-impact melt pool

Chang’E-4 landed in the South Pole-Aitken (SPA) basin, providing a unique chance to probe the composition of the lunar interior. Its landing site is located on ejecta strips in Von Kármán crater that possibly originate from the neighboring Finsen crater. A surface rock and the lunar regolith at 10 sites along the rover Yutu-2 track were measured by the onboard Visible and Near-Infrared Imaging Spectrometer in the first three lunar days of mission operations. In situ spectra of the regolith have peak band positions at 1 and 2 μm, similar to the spectral data of Finsen ejecta from the Moon Mineralogy Mapper, which confirms that the regolith''s composition of the landing area is mostly similar to that of Finsen ejecta. The rock spectrum shows similar band peak positions, but stronger absorptions, suggesting relatively fresh exposure. The rock may consist of 38.1 ± 5.4% low-Ca pyroxene, 13.9 ± 5.1% olivine and 48.0 ± 3.1% plagioclase, referred to as olivine-norite. The plagioclase-abundant and olivine-poor modal composition of the rock is inconsistent with the origin of the mantle, but representative of the lunar lower crust. Alternatively, the rock crystallized from the impact-derived melt pool formed by the SPA-impact event via mixing the lunar crust and mantle materials. This scenario is consistent with fast-cooling thermal conditions of a shallow melt pool, indicated by the fine to medium-sized texture (<3 mm) of the rock and the SPA-impact melting model [Icarus 2012; 220: 730–43].     

对盐类水解反应规律的再思考

水解反应规律:有弱才水解,无弱不水解,弱弱双水解,谁强显谁性,都弱具体定.其中"弱弱双水解"是指弱酸根离子与弱碱根离子的水解相互促进,发生双水解反应,那么弱酸根离子与弱碱根离子相遇是否一定发生双水解反应呢?     

课堂细节描述——推进校本教研有效实施的新技术

观察大量的校本教研现场后,我们在和学校管理者和教师们的交流中发现,对校本教研的规范开展大家都持肯定态度,但同时流露出对校本教研的“质”的担忧。他们把现状归因在缺乏“专业引领”,希望通过专家的介入去改变这种局面。这的确是解决问题的一种办法,但同时也是目前校本教研

知识管理在航空新产品开发中的应用研究/FONT

回顾了国内外关于知识管理理论及知识管理与新产品开发绩效关系方面的研究成果,提出了航空新产品开发中组织要素、知识管理活动和新产品开发绩效之间关系的概念模型和理论假设,基于对航空企业和科研院所的问卷调查数据进行了定量的实证研究。结果表明：知识管理活动的各维度对新产品开发绩效有显著影响;组织结构、组织文化对知识管理活动有显著影响,但IT工具对知识管理活动的影响则不显著,限制IT工具发挥作用的主要原因是其使用的不便利性;组织要素的各维度对新产品开发绩效有显著影响。这些研究结果可以为航空企业或科研院所在推进知识管理时应采取的策略提供有益的参考。     

制度质量、技术创新的挤出效应与资源诅咒—基于我国省际面板数据的实证分析

利用30个省际面板数据验证存在"资源诅咒"的同时,从制度质量和技术创新挤出效应的角度对其产生机理进行了基于门槛模型的实证检验,并对门槛变量的影响因素进行了实证分析。结果表明:1)自然资源和经济发展之间显著的存在基于制度质量和技术投入水平的单门槛效应,制度质量和技术投入水平的提高可以有效地改善资源依赖对经济增长的负面影响;2)资源依赖度是产生诅咒的关键,丰裕的资源虽然和经济增长表现出正相关的关系,但是其对制度质量和技术投入水平的影响是负相关的,资源开发对技术创新具有挤出效应。另外实证结果还显示出产业结构的调整可以在一定程度上缓解经济增长对自然资源的依赖性,但是缺乏稳定性。
