Generating hydrogen gas from methane with carbon captured as pure spheroidal nanomaterials

Energy production by using hydrogen gas as a feedstock is considered to be one of the keys to creating clean energy, with the proviso that the gas is generated in a sustainable way with no emissions. A simple, self-sustaining process generating hydrogen gas from methane using inexpensive stainless steel wire-mesh catalysts at elevated temperatures (800 °C) is reported. A theoretical analysis of the production of electricity by this process revealed peak chain energy efficiencies up to 21% (emission free) when using a percentage of the produced hydrogen (approximately 40% of purified yield) as the heat source. In addition, a practical method has been developed to purify the carbon byproduct, affording essentially pure highly graphitic spheroidal carbon for advanced materials applications.     

建立多渠道投资机制促进实验室建设

在国家教委颁布的《关于加强高校实验室工作意见》文件中指出：“实验室建设是办好高校、培养合格人材的一项基础性工作”。实验室在育人方面有其独特作用,不仅可以授人知识和技术,培养学生动手能力、分析问题与解决问题的能力,而且影响人的世界观、思维方法和作风。近代科技发展史表明,对经济建设有重大影响的发明,多数来自实验室,愈是现代科技愈是依靠科学实验来发展。可见,实验室在高等学校有着重要的地位。加强实验室建设,其中实验室建设经费是最重要的物质基础,为了学科建设,改善实验室的教学条件,我校采取了以下措施。　１…     

Construction of a High-Quality Organic-Inorganic Hybrid Heterostructure and Its Photo-response Performance

The combination of metal oxide and organic semiconductor for constructing organic–inorganic hybrid heterostructure is promising to offer unique optoelectronic properties. However, the distinct difference in electron structure and processing technology of the two types of materials makes it usually difficult to fully deliver their complementary advantages. Herein, we report the construction of a high quality organic/In₂O₃ hybrid heterostructure presenting a good ambipolar transport with average electron mobility >1 cm²·V^–1·s^–1 and hole mobility up to 0.4 cm²·V^–1·s^–1, respectively, together with a high-gain inverter. In addition, the incorporation with organic film on top of In₂O₃ remarkably reduces the dark current, enabling the realization of high photoconductivity response with photosensitivity of two magnitudes higher than that of pure In₂O₃. The photoconductor and phototransistor of the hybrid structure demonstrate high photoresponsivity >10³ AW^–1 and detectivity up to 10¹⁴ Jones, demonstrating the promising functionality of such a high quality hybrid heterostructure.
