Lobane-ty.e diterpenoids are not frequently.discovered from marine soft corals. In this paper, three new lobane ty.e diterpenes, 13-methoxy.oba-8,10,15(16),17(18)-tetraene(1), 8,10,13(15)z.16 E-lobatetraene(2) and 19-hy.roxy.lobatetraene(3), and a new natural compound, 17,18-epoxy.oba-16-acetoxy.8,10,13(15)-trien(4), co-occurring with a known related diterpenoid, 18-methoxy.oba-8,10,13(15),16(17)-tetraene(5), were isolated from the South China Sea soft coral Sinularia poly.acty.a. The structures of new compounds were determined by.extensive spectroscopic analy.is and by.comparison with those reported in the literature. In bioassay. all the isolates were inactive on antibacterial, PTP1 B inhibitory. and immunological activities. This study.increased the chemical diversity.of marine diterpenoids.

As to PIN ty.e a-Si based solar cells, the performance of p-lay.r, such as absorption coefficient, band gap and stability. has great influence upon the performances and stability.of the cells. Using RF-PECVD technology. a wide gap window material SiO: H for p ty.e lay.r was achieved with CO and BH as the dopants, whose performances was better than that of the window material SiC: H with CH and BH as the dopants, for example, its conductance reaches ～10s/cm and band gap Eg reached 2.14eV. It was discovered

Combining metal to form metal phosphide is a promising strategy.to address the fast capacity.decay.of P rooted from its low electronic conductivity.and large volume changes upon cy.ling. Cu_(3)P, which possesses a high theoretical gravimetric and volumetric capacity.of 363 m Ahág^(-1) and 1028 AháL^(-1) and reasonable volume expansion of 156% during sodiation, was investigated as anode material in SIBs. Hollow-structured Cu_(3)P electrode delivers an initial de-sodiation capacity.of * 159.0 m Ahág^(-1) with high capacity.retention of ~85.1% over 50 cy.les at 0.2 C rate and exhibits good rate performance,retaining 70% of the capacity.when the current density.increases from 0.2 C to 1.6 C. A 3 V-class full cell consisting of P2-Na_(2/3) Ni_(1/3) Mn_(1/2) Ti_(1/6)O_(2) cathode and Cu_(3)P anode was also assembled, which could achieve an energy.density.of ~189.3 Whákg^(-1)(based on the mass of both electrode materials) and average discharge voltage of~2.91 V when cy.led in 1.0-4.3 V at 0.1C.
