How relevant are S=O and P=O Double Bonds for the Description of the Acid Molecules H2SO3, H2SO4, and H3PO4, respectively? The acid molecules H 2 SO 3 , H 2 SO 4 , and H 3 PO 4 are usually drawn using "Lewis structures" which exhibit the octet extension by 3d-orbitals on su...
Enter the formula of a chemical compound to find the oxidation number of each element. A net ionic charge can be specified at the end of the compound between { and }. For example: ZnCl4{2-} or NH2NH3{+}. Enter just an element symbol to show the common and uncommon oxidation states ...
SEPARATION OF SCANDIUM FROM YTTRIUM, RARE EARTHS, THORIUM, ZIRCONIUM, URANIUM, AND OTHER ELEMENTS BY ANION EXCHANGE CHROMATOGRAPHY IN AMMONIUM SULFATE MEDIA Sc(III) is adsorbed on a strongly basic anion exchange resin, Dowex 1, X-8 (sulfate form), from 0.1 M (NH4)2-SO4-0.025M H2SO4 solut...
which is submitted to a Swern oxidation to afford the corresponding ketone (XIII). The enolization of (XIII) with TBDMS-OTf and DIEA gives the silylated enol ether (XIV), which is finally cyclized to the target ketone (IV) by means of Lewis acids such as TiCl4, BF3.Et2O, SnCl4 or ...
Using this system, we induced senescence by the addition of 4-hydroxytamoxifen (4OHT) to primary fibroblasts and assayed cells for established senescence markers (Fig. 1a; Supplementary Fig. 1). Consistent with our previous findings15, we detected a striking loss of H3K4me3 during senescence (...
