X-ray-diffraction patterns of hyaluronate fibres from a variety of sources were obtained. Sodium hyaluronate gives well-defined patterns which index on a hexagonal unit cell with dimensions a=1.17+/-nm and a fibre repeat-distance of 2.85+/-0.03nm. A further form of sodium hyaluronate is produced by annealing at 60 degrees C in 75% relative humidity. This stable state indexes on a hexagonal unit...

Iridates are of current great interest for their entangled spin-orbital state and possibly exotic properties. In this work, using density functional calculations, we have demonstrated that the hexagonal spin-chain materials Sr3MIrO6 (M = Ni, Co) are an iridate system in which the spin-orbit coupling (SOC) tunes the magnetic and electronic properties. The significant SOC alters the orbital state...

The deuterium nuclear magnetic resonance (2H NMR) spectrum of perdeuterated tetradecanol in a mixture of 1-palmitoyl-2-oleoyl-phosphatidylethanolamine (POPE) and water was used to compare the variation of the acyl chain orientational order parameter, S(n), with carbon position, n, in the liquid crystalline lamellar (La) and hexagonal (HI,) phases. The characteristic independence of S(n) with n ...

In this paper, a lossy partition coding technique is presented which leads to decoded partitions with unnoticeable losses. It uses an hexagonal grid for contour representation and it is based on the concept of Multi-Grid Chain Code. This coding technique can be used in intra-frame mode or, in combination with partition prediction techniques, in inter-frame mode. In intra-frame mode, it leads to...

conclusions hexagonal water has no significant effect(s) on total cholesterol, hdl, and ldl; however, more experiments are needed to clarify all aspects of hexagonal water consumption on diabetes. background diabetes is one of the most prevalent abnormalities in all over the world. nowadays, there are lots of attempts to reduce its disturbances and defects by changing life style to access some ...

Atomic force microscopy was used to investigate the mixed monolayer of FC- and HC-amphiphiles. Clear topographic images showing domain structure of the mixed monolayer and the data of the domain size have been provided. It is revealed that in the mixed monolayer the sodium octadecanesulfonate molecules construct the hexagonal domain dispersing in the continuous two-dimensional phase of perfluor...

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...
