Investigations on Growth, Optical and Thermal Properties of Sulphamic Acid Single Crystals

D. Jaishree、G. Kanchana、R. Kesavasamy2014-01-01Advances in Condensed Matter Physics

Single crystals of sulphamic acid of 11 × 7 × 3 mm 3 dimension were successfully grown by slow evaporation technique. The crystal structure of grown crystals was confirmed by single crystal X-ray diffraction analysis. The presence of functional groups in the crystal lattice has been qualitatively determined by FT-IR a…

Growth of rutile TiO 2 on the convex surface of nanocylinders: from nanoneedles to nanorods and their electrochemical properties

Junhua Kong、Yuefan Wei、Chenyang Zhao 等 9 位作者2014-01-01Nanoscale

In this work, bundles of rutile TiO₂ nanoneedles/nanorods are hydrothermally grown on carbon nanofibers (CNFs), forming free-standing mats consisting of three dimensional hierarchical nanostructures (TiO₂-on-CNFs). Morphologies and structures of the TiO₂-on-CNFs are studied using a field-emission scanning electron mic…

Remarkable enhancement of the photoreactivity of a polyfluoroalkyl azobenzene derivative in an organic–inorganic nano-layered microenvironment

Vivek Ramakrishnan、Daisuke Yamamoto、Shin Sasamoto 等 7 位作者2014-01-01Physical Chemistry Chemical Physics

Organic-inorganic hybrids composed of polyfluoroalkyl azobenzene surfactant (abbreviated as C3F-Azo-C6H) and inorganic layered compounds are able to undergo reversible three-dimensional morphology changes such as interlayer space changes and nanosheet sliding in a giant scale due to reversible trans-cis isomerization…

A designer peptide as a template for growing Au nanoclusters

Roberto de la Rica、Lesley W. Chow、Christine‐Maria Horejs 等 8 位作者2014-01-01Chemical Communications

A peptide was designed to generate a sub-nanometric template that guides the growth of fluorescent gold nanoclusters. The peptide was endorsed with nucleating moieties and a three-dimensional structure that arrests the growth of ultrasmall nanoparticles. The nanoclusters are not cytotoxic and can be found in the cytos…

Alternation and tunable composition in hydrogen bonded supramolecular copolymers

Thorsten Felder、Tom F. A. de Greef、Marko M. L. Nieuwenhuizen 等 4 位作者2014-01-01Chemical Communications

Sequence control in supramolecular copolymers is limited by the selectivity of the associating monomer end groups. Here we introduce the use of monomers with aminopyrimidinone and aminohydroxynaphthyridine quadruple hydrogen bonding end groups, which both homodimerize, but form even stronger heterodimers. These featur…

Transition metal-doped BiFeO 3 nanofibers: forecasting the conductivity limit

Qiang Xu、Mushtaq A. Sobhan、Franklin Anariba 等 6 位作者2014-01-01Physical Chemistry Chemical Physics

We investigate the limiting electrical conductivity of BiFeO3 (BFO) nanofibers via first-principles modelling and experiments. Based on a semi-empirical approach, all transition metals are first screened for their suitability to form an acceptor in BFO. The resultant candidates (e.g., Ni, Cu and Ag) are further studie…

The ultrastructure of type I collagen at nanoscale: large or small D-spacing distribution?

Hai‐Nan Su、Liyuan Ran、Zhihua Chen 等 9 位作者2014-01-01Nanoscale

D-Spacing is the most significant topographic feature of type I collagen fibril, and it is important for our understanding of the structure and function in collagens. Traditionally, the D-spacing of type I collagen fibril was shown to have a singular value of 67 nm, but recent works indicated that the D-spacing values…
