Article Title: Solvent-free mechanochemical synthesis of alane, AlH3: effect of pressure on the reaction pathway Article Snippet: Nearly quantitative mechanochemical synthesis of non-solvated AlH3 from lithium aluminium hydride (LiAlH4) and aluminium chloride (AlCl3) has been achieved at room temperature under reasonably low pressure of hydrogen (210 bar) or inert gas (125 bar for He or 90 bar for Ar).. X-ray diffraction, solid-state Al NMR spectroscopy, and temperature programmed desorption analyses of as-milled materials reveal a nearly complete conversion of a 3 : 1 (molar) mixture of LiAlH4 and AlCl3 to a 4 : 3 (molar) mixture of AlH3 and LiCl in ca.. 30 min. By applying pressure of 210 bar or less (depending on the gas: hydrogen, helium, or argon), competing reactions leading to formation of metallic aluminium can be completely suppressed.

Article Snippet: Polyalanine (polyA) sequences are well known as the simplest sequence that naturally forms anti-parallel b-sheets and constitute a key element in the structure of spider and wild silkworm silk fibers.. We have carried out a systematic analysis of the packing of anti-parallel b-sheets for (Ala)n, n = 5, 6, 7 and 12, using primarily C solid-state NMR and MD simulation.. HFIP and TFA are frequently used as the dope solvents for recombinant silks, and polyA was solidified from both HFIP and TFA solutions by drying.

Article Snippet: Alanine oligomers provide a key structure for silk fibers from spider and wild silkworms.We report on structural analysis of L-alanyl-L-alanyl-L-alanyl-L-alanine (Ala)4 with anti-parallel (AP) b-structures using X-ray and solid-state NMR.. All of the Ala residues in the (Ala)4 are in equivalent positions, whereas for alanine trimer (Ala)3 there are two alternative locations in a unit cell as reported previously (Fawcett and Camerman, Acta Cryst., 1975, 31, 658–665). (Ala)4 with AP b-structure is more stable than AP-(Ala)3 due to formation of the stronger hydrogen bonds.. The intermolecular structure of (Ala)4 is also different from polyalanine fiber structure, indicating that the interchain arrangement of AP bstructure changes with increasing alanine sequencelength.
