Characterization of the molar mass distribution (MMD) poly (ether ether ketone) (PEEK) is very troublesome due to insolubility PEEK in common solvents. The solubility may be substantially improved after its sulfonation. Sulfonated (SPEEK) was prepared by sulfonation with 98% concentrated H2SO4 at room temperature. presence sulfonic acid group (-SO3H) matrix confirmed nuclear magnetic resonance ...

N,N-Dimethylacetamide (DMA) is a water-miscible solvent, FDA approved as excipient and therefore widely used as drug-delivery vehicle. As such, DMA should be devoid of any bioactivity. Here we report that DMA is epigenetically active since it binds bromodomains and inhibits osteoclastogenesis and inflammation. Moreover, DMA enhances bone regeneration in vivo. Therefore, our in vivo and in vitro...

An excess of elemental iodine in N,N-dimethylacetamide enables effective 3/iodanylium-de-hydronation of terminal alkenes with 3-iodopropene derivatives and hydrogen iodide formation within minutes at room temperature. The optimal molar ratio of iodine to substrate was decreased to 1 : 1 when hydrogen iodide formed was oxidized on a platinum anode. The electrolytic oxidation recovers iodine as a...

Two unprecedented 3D porous anionic metal-organic frameworks, [Me2NH2]2[Cd2(bpdc)3].4dma 1 and [Me2NH2]2[Cd2(NH2bdc)3].4dma 2 (dma = N,N'-dimethylacetamide, bpdc = 4,4'-biphenyldicarboxylate, NH(2)bdc = 2-amino-1,4-benzenedicarboxylate) have been solvothermally synthesized with a dimethylammonium cations template. Both 1 and 2 are constructed from low-symmetry SBUs. 1 has a chiral framework wit...
