More and more studies are based on digital microstructures of cement pastes obtained either by numerical modelling or by experiments. A comprehensive understanding of the their pore structures, therefore, becomes significant. In this study, the pore structure of a virtual cement paste (HYMO-1d) generated by cement hydration model HYMOSTRUC 3D is characterized. The pore structure of HYMO-1d is c...

A simple and mild wet-chemical approach was developed for the synthesis of one-dimensional (1D) In(OH)(3) nanostructures. By calcining the 1D In(OH)(3) nanocrystals in air at 250 degrees C, 1D In(2)O(3) nanocrystals with the same morphology were obtained. TEM results show that both 1D In(OH)(3) and 1D In(2)O(3) are composed of uniform nanotube bundles. SAED and XRD patterns indicate that 1D In(...

Well-defined CdS nanograin-sensitized one-dimensional (1D) Zr:α-Fe2O3 nanostructured arrays with enhanced photoelectrochemical performance are synthesized directly on F-doped SnO2 (FTO) using the hydrothermal method. Owing predominantly to the appropriate photogenerated electron-hole separation and charge collection in 1D Zr:α-Fe2O3 nanorods, hydrothermally deposited CdS/1D Zr:α-Fe2O3 samples e...

Nanotubes, nanowires and nanobelts are important one-dimensional (1D) nanomaterials that are the foundation for nanoscience and nanotechnology (Fig. 1a). 1D nanomaterials have important applications in electronics, optoelectronics, sensors, biomedical science, environmental science, green energy and advanced defence technologies. This themed issue on inorganic 1D nanomaterials gathers papers ab...

We report the preparation of novel quasi-one-dimensional (quasi-1D) C60 nanostructures on rippled graphene. Through careful control of the subtle balance between the linear periodic potential of rippled graphene and the C60 surface mobility, we demonstrate that C60 molecules can be arranged into a quasi-1D C60 chain structure with widths of two to three molecules. At a higher annealing temperat...

Thyroid-associated ophthalmopathy (TAO) is a potentially severe autoimmune disease, in and around the orbit, usually accompanied by Graves' disease. It was the goal of this study to develop a serological indicator for TAO and to characterize its expression in human thyroid and eye muscle tissue. Thus, we have recloned the full-length 1D-complementary DNA and assessed its expression levels in 90...

We study the low-temperature transport properties of 1D quantum wires as the confinement strength V_{conf} and the carrier density n_{1D} are varied using a combination of split gates and a top gate in GaAs/AlGaAs heterostructures. At intermediate V_{conf} and n_{1D}, we observe a jump in conductance to 4e;{2}/h, suggesting a double wire. On further reducing n_{1D}, plateau at 2e;{2}/h returns....

We prepare a chemically and thermally one-dimensional (1D) quantum degenerate Bose gas in a single microtrap. We introduce a new interferometric method to distinguish the quasicondensate fraction of the gas from the thermal cloud at finite temperature. We reach temperatures down to kT≈0.5ℏω(⊥) (transverse oscillator eigenfrequency ω(⊥)) when collisional thermalization slows down as expected in ...

Proper leaf development is essential for plant growth and development, and leaf morphogenesis is under the control of intricate networks of genetic and environmental cues. We are interested in dissecting these regulatory circuits genetically and report here the isolation of two Arabidopsis dominant mutants, abnormal shoot5-1D (abs5-1D) and abs7-1D identified through activation tagging screens. ...

We introduce a new approach to analyse the global structure of electronic states in quasi-1D models in terms of the dynamics of a system of parametric oscillators with time-dependent stochastic couplings. We thus extend to quasi-1D models the method previously applied to 1D disordered models. Using this approach, we show that a “delocalisation transition” can occur in quasi-1D models with weak ...
