Robust Protection of III-V Nanowires in Water Splitting by a Thin Compact TiO Layer.

Narrow-band-gap III-V semiconductor nanowires (NWs) with a suitable band structure and strong light-trapping ability are ideal for high-efficiency low-cost solar water-splitting systems. However, due to their nanoscale dimension, they suffer more severe corrosion by the electrolyte solution than the thin-film counterparts. Thus, short-term durability is the major obstacle for using these NWs for practical water-splitting applications.

Zn and N Codoped TiO Thin Films: Photocatalytic and Bactericidal Activity.

We explore a series of Zn and N codoped TiO thin films grown using chemical vapor deposition. Films were prepared with various concentrations of Zn (0.4-2.

Multimodal Prussian blue analogs as contrast agents for X-ray computed tomography.

Prussian blue analogs (PBAs) are versatile materials with a wide range of applications. Due to their tunability, intrinsic biocompatibility, as well as low toxicity, these nanoscale coordination polymers have been successfully studied as multimodal contrast agents for multiple imaging techniques. Herein, we report the expanded biomedical application of PBAs to X-ray computed tomography (CT).

(E)-N'-(3-Eth-oxy-4-hy-droxy-benzyl-idene)-4-meth-oxy-benzohydrazide.

In the mol-ecule of the title benzohydrazide derivative, C(17)H(18)N(2)O(4), the dihedral angle between the benzene rings is 6.86 (11)°. The meth-oxy group of the 4-meth-oxy-phenyl fragment deviates slightly [C(methyl)-O-C-C = 10.

(E)-4-Meth-oxy-N'-(3,4,5-trimeth-oxy-benzyl-idene)benzohydrazide.

In the asymmetric unit of the title compound, C(18)H(20)N(2)O(5), there are two crystallographic independent mol-ecules. Both mol-ecules are twisted; the dihedral angle between the two benzene rings is 7.2 (5)° in one mol-ecule, whereas it is 85.

(E)-N'-(3-Hy-droxy-4-meth-oxy-benzyl-idene)-4-meth-oxy-benzohydrazide.

The title mol-ecule, a benzohydrazide derivative, C(16)H(16)N(2)O(4), is twisted with a dihedral angle of 69.97 (5)° between the two benzene rings. An intra-molecular O-H⋯O hydrogen bond generates an S(5) ring motif.

(E)-N'-(2,3-Dihy-droxy-benzyl-idene)-4-meth-oxy-benzohydrazide.

The mol-ecule of the title benzohydrazide derivative, C(15)H(14)N(2)O(4), is twisted and exists in a trans conformation with respect to the C=N double bond. The dihedral angle between the benzene rings is 56.86 (9)° and the C atom of the meth-oxy group deviates slightly [C-O-C-C = -10.
