Short complementary B-form DNA oligomers, 6 to 20 base pairs in length, are found to exhibit nematic and columnar liquid crystal phases, even though such duplexes lack the shape anisotropy required for liquid crystal ordering. Structural study shows

Porphyrin-based materials are prime candidates for solar energy harvesting applications. New compounds incorporating the porphyrin core, which exhibit the columnar liquid crystal (LC) phase, were synthesized as they offer a route to obtaining defect-

A combination of position-resolved synchrotron microbeam techniques was used to explore the distribution and role of trace transition metals in the jaws of Glycera dibranchiata. The mandibles of this marine sediment worm have recently been found to b

We present a new method of sub-Angstrom resolution imaging of the 3D structure of epitaxial films and their interface with the substrate. The method utilizes the diffraction intensities along the substrate-defined Bragg rods and some crude knowledge

Higher animals typically rely on calcification to harden certain tissues such as bones and teeth. Some notable exceptions can be found in invertebrates: The fangs, teeth, and mandibles of diverse arthropod species have been reported to contain high l

X-ray diffraction (XRD) and extended X-ray absorption fine structure (EXAFS) data were used to explore the structure of cathodically deposited thin films of nickel hexacyanoferrate (NiHCF). Thin films were electrodeposited on Pt substrates and analyz

Resonant X-ray diffraction results on polycrystalline and single crystal Yb4As3 are reported. The strong resonant enhancement of particular superlattice reflections at temperatures below the first-order phase transition gives direct evidence of one-d

X-ray absorption near-edge structure (XANES) spectroscopy has been applied to the speciation of 24 simulated soil samples spiked with known concentrations (8–1015 ppm) of hexavalent and trivalent chromium. For XANES spectroscopy, multivariate calib
