TiO2 nanotubes with ultrathin walls for enhanced water splitting
(
Royal Society of Chemistry
, 2015 , Article)
We demonstrate, for the first time, the synthesis of titania nanotubes
with ultrathin (3–5 nm) wall thickness. As revealed by the incident
photon-to-current collection efficiency (IPCE) and electrochemical
impedance ...
Crystal structure of (E)-2-{[(6-methoxy-1,3-benzothiazol-2-yl)imino]methyl}phenol
(
International Union of Crystallography
, 2015 , Article)
The title compound, C15H12N2O2S, crystallizes in the orthorhombic space group Pna21, with two molecules in the asymmetric unit (Z′ = 2). Each molecule consists of a 2-hydroxy Schiff base moiety linked through a spacer ...
Bordetella pertussis risA, but not risS, is required for maximal expression of Bvg-repressed genes
(
American Society for Microbiology
, 2005 , Article)
Expression of virulence determinants by Bordetella pertussis, the primary etiological agent of whooping cough, is regulated by the BvgAS two-component regulatory system. The role of a second two-component regulatory system, ...
