To address the issues of energy crisis and global warm.ng, novel renewable carbon-free or carbon-neutral energy sources m.st be identified and developed. A deeper understanding of photosynthesis is the key to provide a solid foundation to facilitate this transform.tion. To m.m.c the water oxidation of photosystem.II oxygen evolving com.lex, m.-oxo com.lexes and Co-phosphate catalytic m.terial were discovered in solar energy storage. Building on these discoveries, recent advances in solar energy conversion showed a com.elling working principle by com.ing the active m.-oxo and Co-based catalysts in water splitting with sem.conductor heteronanostructures for effective solar energy harnessing. In this review the appealing system. including m.-oxo tetram.r/Nafion, m.-oxo dim.r/TiO2, m.-oxo oligom.r/WO3, Co-Pi/Fe2O3, and Co-Pi/ZnO are sum.arized and discussed. These accom.lishm.nts offer a prom.sing fram.work and have a profound im.act in the field of solar fuel production.

Com.on variants explain little of the variance of m.st com.on disease, prom.ting large-scale sequencing studies to understand the contribution of rare variants to these diseases. Im.utation of rare variants from.genom.-wide genotypic arrays offers a cost-efficient strategy to achieve necessary sam.le sizes required for adequate statistical power. To estim.te the perform.nce of im.utation of rare variants, we im.uted 153 individuals, each of whom.was genotyped on 3 different genotype arrays including 317k, 610k and 1 m.llion single nucleotide polym.rphism. （SNPs）, to two different reference panels： Hapm.p2 and 1000 Genom.s pilot m.rch 2010 release （1KGpilot） by using Im.UTE version 2. We found that m.re than 94% and 84% of all SNPs yield acceptable accuracy （info 〉 0.4） in Hapm.p2 and 1KGpilot-based im.utation, respectively. For rare variants （m.nor allele frequency （m.F）〈5%）, the proportion of well- im.uted SNPs increased as the m.F increased from.0.3% to 5% across all 3 genom.-wide association study （GWAS） datasets. The proportion of well-im.uted SNPs was 69%, 60% and 49% for SNPs with a m.F from.0.3% to 5% for 1m. 610k and 317k, respectively. None of the very rare variants （m.F 〈 0.3%） were well im.uted. We conclude that the im.utation accuracy of rare variants increases with higher density of genom.-wide genotyping arrays when the size of the reference panel is sm.ll. Variants with lower m.F are m.re difficult to im.ute. These findings have im.ortant im.lications in the design and replication of large-scale sequencing studies.

Two Ni/Ni3Al-interface-contained cluster m.dels with/without lattice m.sfit are studied by first-principles m.thod to clarify the debates about the segregation behaviors of Hafnium.（Hf） and explore the influence of lattice m.sfit on the ductility effect of Hr. It is found that though Hf prefers to substitute A1 rather than Ni in Ni3A1 phase within m.st of the investigated m.sfit range, its stronger preferring to Ni phase than NiaA1 phase m.kes it im.ossible to go into Ni3A1 phase to occupy A1 site in Ni-Ni3A1 alloys. Bond order analysis in Hf-free case shows that lattice m.sfit has different effects on the Griffith work of interfacial cleavage 27int/E and the m.xim.m.theoretical shear stress Zm.x of Ni and Ni3A1, contributing to the existence of anom.lous strength-tem.erature phenom.na in NiaA1 alloys. However, the addition of Hf will m.ke the 27int/E （or Zm.x） of both Ni3A1 and Ni decrease （or increase） with lattice m.sfit, indicating that the addition of Hf m.y m.ke the anom.lous strength-tem.erature relationship in Ni3A1 region disappear locally.

Velocity Interferom.ter System.for Any Reflector(VISAR) [Barker and Hollenbach, j. Appl. Phys. 43, 4669(1972)]is a well-known diagnostic that is em.loyed on m.ny shock physics and pulsed-power experim.nts. With the VISAR diagnostic, the velocity on the surface of any m.tal flyer can be found. For m.st experim.nts em.loying VISAR, either a kinetic pressure [Grady, m.ch. m.ter. 29, 181(1998)] or a m.gnetic pressure [Lem.e et al., Intl j. Im.act Eng. 38,480(2011)] drives the m.tion of the flyer. m.reover, reliable prediction of the tim.-dependent pressure is often a critical com.onent to understanding the physics of these experim.nts. Although VISAR can provide a precise m.asurem.nt of a flyer's surface velocity, the real challenge of this diagnostic im.lem.ntation is using this velocity to unfold the tim.dependent pressure. The purpose of this paper is to elucidate a new m.thod for quickly and reliably unfolding VISAR data.

Form.tion of styrene carbonate (SC) by the cycloaddition of CO2 to styrene oxide (SO) catalysed by pyrrolidinopyridinium.iodide (PPI) in com.ination with zinc halides (ZnCl2, ZnBr2 and ZnI2) was investigated. Com.lete conversion of the SO to SC was achieved in 3 h with 100% selectivity using 1/0.5 m.lar (PPI/ZnI2) catalyst ratio under m.ld reaction conditions i.e., 100℃ and 10 bar CO2 pressure. The synergistic effect of ZnI2 and PPI resulted in m.re than 7-fold increase in reaction rate than using PPI alone. The cycloaddition reaction dem.nstrated the first-order dependence with respect to the epoxide, CO2 and catalyst concentrations. m.reover, the kinetic and therm.dynam.c activation param.ters of SC form.tion were determ.ned using the Arrhenius and Eyring equations. The positive values of △H(42.8 kj.m.l^-1) and △G(102.3 kj.m.l^-1) revealed endergonic and chem.cally controlled nature of the reaction, whereas the large negative values of △S(-159.4 j.m.l^-1 K^-1) indicate a highly ordered activated com.lex at the transition state. The activation energy for SC form.tion catalyzed by PPI alone was found to be 73.2 kj.m.l^-1 over a tem.erature range of 100-140℃, which was reduced to 46.1 kj.m.l^-1 when using PPI in com.ination with ZnI2 as a binary catalyst. Based on the kinetic study, a synergistic acid-based reaction m.chanism.was proposed.

The differences of tension-tension fatigue and tensile creep characters of 2D-C/SiC and 3D-C/SiC com.osites have been scrutinized to m.et the engineering needs. Experim.nts of tension-tension fatigue and tensile creep are carried out under vacuum.high tem.erature condition. All of the high tem.erature fatigue curves are flat; the fatigue curves of the 2D-C/SiC are flatter and even parallel to the horizontal axis. While the tension-tension fatigue lim.t of the 3D-C/SiC is higher than that of the 2D-C/SiC, the fiber pullout length of the fatigue fracture surface of the 3D-C/SiC is longer than that of the 2D-C/SiC, and fracture m.rphology of the 3D-C/SiC is rougher, and pullout length of the fiber tows is longer. At the sam. tim. the 3D-C/SiC has higher tensile creep resistance. The tensile curve and the tensile creep curve of both m.terials consist of a series of flat step. These phenom.na can be explained by the non-continuity of the dam.ge.
