分子模拟作为一个重要的理论研究手段,可以在微观分子世界与宏观可观测量之间搭建桥梁,从而为人们在分子水平上理解物质的结构和动力学性质提供工具,其在化学化工、生物医药、能源、材料等多个领域都有广泛的应用。虽然近几十年来国际学术界和工业界已发展出很多具有特色的分子模拟软件,如AMBER、CHARMM、GROMACS、LAMMPS、ACEMD和Material Studio等,但是在分子模拟领域国内一直没...
Researchers have discovered for the first time that a common marine sponge hosts bacteria that specialize in the production of toxic compounds nearly identical to man-made fire retardants, a finding t...
A Scripps Institution of Oceanography at the University of California San Diego-led research team discovered for the first time that a common marine sponge hosts bacteria that specialize in the produc...
Mixtures of biosiliceous and heterozoan-dominated carbonate deposits are commonly interpreted as recording cold-water polar or deep basinal conditions. However, a growing body of literature is documen...
We measured ammonium and nitrate plus nitrite fluxes from 14 common spongespecies on a Florida Keys reef (Conch Reef) using a combination of incubation experiments and an in situ method that requires ...

We present detailed records of trace metals and carbon isotopes to understand siliceous spicule formation in the deep-sea lithistid sponge Corallistes undulatus Le′vi and Le′vi, 1983 (Demospongiae: C...
Coral reef ecosystems are characterized by high species diversity and intense levels of biotic interaction, particularly competition for space among sessile benthic invertebrates. Using in situ pulse ...
The vast majority of organic matter in the world ocean is found in the dissolved pool. However, no evidence has been demonstrated for direct uptake of bulk dissolved organic matter (DOM) by organisms...
Two bisabolane type sesquiterpene phenols, (+)-curcuphenol (1) and (+)-curcudiol (2), were isolated from a Philippine marine sponge, Didiscus sp., in addition to b -sitosterol (3) and phenethylamine (...
The solvent effect on Verongia aerophoba metabolites during the extraction and isolation processes were examined in this study. A major compound (6), a stereoisomer of fistularin-3, and a new compound...
