Developing high-performing non-noble transition metal catalysts for H_(2) evolution from chemical hydrogen storage materials is of great significance for the hydrogen economy system, yet challenging. Herein,we present for the first time that anomalous metastable hexagonal close-packed Ni nanoparticles induced by heteroatom N doping encapsulated in carbon(N-hcp-Ni/C) can exhibit admirable catalytic performance for ammonia borane(AB) dehydrogenation, prominently outperforming conventional fcc Ni counterpart with similar morphology and favorably presenting the state-of-the-art *** experimental and theoretical studies unravel that unusual hcp phase engineering of Ni together with N doping could induce charge redistribution and modulate electronic structure, thereby facilitating H_(2)O adsorption and expediting H_(2)O dissociation(rate-determining step). As a result, AB dehydrogenation can be substantially boosted with the assistance of N-hcp-Ni/C. Our proposed strategy highlights that unconventional crystal phase engineering coupled with non-metal heteroatom doping is a promising avenue to construct advanced transition metal catalysts for future renewable energy technologies.

Elevated working temperatures reduce the efficiency of dye-sensitized solar cells （DSCs）, and effective temperature regulation protects them from the undesirable efficiency loss. In this work, a semi-transparent DSC module equipped with a cooling sys- tem was designed and constructed for application in buildings, the temperature and output performance of the modules with or without cooling treatment were investigated. The test results showed the cooling system could noticeably improve the power generation and reduce the module temperature. Moreover, we established a mathematical model to analyze the modules＇ ther- mal performances, and introduced the concept of cooling efficiency to evaluate the cooling effect. The model accuracy have been validated utilizing measured data, and the effects of channel depth and mass flow rate on the module temperature and cooling efficiency were further theoretically studied. The combined DSC module has been found to have a good application prospect in building integrated photovoltaic （BIPV）, and the numerical results are important in system design.

Mycobacterium smegmatis porin A(MspA), possessing a short(～0.6 nm) and narrow(～1.2 nm) constriction that enables its high spatial resolution of sensing, has emerged as an optimum choice for nanopore sequencing and nano-reactive sensing. However, prepared Msp A nanopores cannot be obtained from any commercial vendors. We here provide a highly simplified protocol for Msp A preparation. The protocol yields ～10 mg fully oligomerized protein per liter of culture and is straightforward to *** the prepared Msp A nanopores, discrimination of immobilized ss DNA oligonucleotides can be performed, which serves as a demo application to demonstrate core procedures of single molecule sensing using MspA. This method is also in principle compatible with all other Msp A mutants, which might merit the need to develop a variety of MspA based nano-reactive sensors.

2’-deoxy-2’-fluoroarabinonucleic acid（FANA）,which is one type of xeno-nucleic acid（XNA）,has been intensively studied in molecular medicine and synthetic biology because of its superior gene-silencing and catalytic *** urgently required,FANA cannot be directly sequenced by any existing *** sequencing,which identifies a single molecule analyte directly from its physical and chemical properties,shows promise for direct XNA *** a proof of concept,different FANA homopolymers show well-distinguished pore blockage signals in a Mycobacterium smegmatis porin A（MspA） *** ligating FANA with a DNA drive-strand,direct FANA sequencing has been demonstrated using phi29 DNA polymerase by Nanopore-Induced Phase Shift Sequencing（NIPSS）.When bound with an FANA template,the phi29 DNA polymerase shows unexpected reverse transcriptase activity when monitored in a single molecule *** further investigations into the ensemble,phi29 DNA polymerase is shown to be a previously unknown reverse transcriptase for FANA that operates at room temperature,and is potentially ideal for nanopore *** results represent the first direct sequencing of a sugar-modified XNA and suggest that phi29 DNA polymerase could act as a promising enzyme for sustained sequencing of a wide variety of XNAs.

通过分析偏压条件下染料敏化太阳电池的电流电压特性,给出遮挡情况下染料敏化太阳电池组件的电学模型。模拟分析部分遮挡情况下,染料敏化太阳电池组件的输出特性和功率损失,以及反向导通时染料敏化太阳电池的负载特性。结果表明:部分遮挡情况下并联组件中被遮挡电池处于正偏压下,由于难以被击穿,能耗极小。串联组件中被遮挡电池易工作在负偏压区域而成为耗能负载,但作为负载的功率较低。
