Phyllofenones F-M, Scalarane Sesterterpenes from the Marine Sponge .

Eight new scalarane sesterterpenes, phyllofenones F-M (-), together with two known analogues, carteriofenones B and A (-), were isolated from the marine sponge collected from the South China Sea. The structures of these compounds were determined based on extensive spectroscopic and quantum chemical calculation analysis. The antibacterial and cytotoxic activity of these compounds was evaluated.

Controllable Connection of FeSe Double Chains and Fe(dien) Complexes for Organic-Inorganic Hybrid Ferrimagnet with a Large Coercivity.

Organic-inorganic hybrid materials built by inorganic and organic building units have attracted intensive interest in the past decades due to unique chemical and physical properties. However, rare organic-inorganic hybrid materials show excellent permanent magnetic properties. Here, we develop a facile chemical solution method to bottom-up synthesize a new hybrid (FeSe)[Fe(dien)].

Anisotropic Growth and Magnetic Properties of α″-FeN@C Nanocones.

α″-FeN nanomaterials with a shape anisotropy for high coercivity performance are of interest in potential applications such as rare-earth-free permanent magnets, which are difficult to synthesize in situ anisotropic growth. Here, we develop a new and facile one-pot microemulsion method with Fe(CO) as the iron source and tetraethylenepentamine (TEPA) as the N/C source at low synthesis temperatures to fabricate carbon-coated tetragonal α″-FeN nanocones. Magnetocrystalline anisotropy energy is suggested as the driving force for the anisotropic growth of α″-FeN@C nanocones because the easy magnetization direction of tetragonal α″-FeN nanocrystals is along the c axis.
