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...

A new synthetic approach to highly substituted triphenylboroxines 11 is described. Their mesomorphic properties were investigated by differential scanning calorimetry (DSC), polarizing optical microscopy (POM) and X-ray diffraction (SAXS, WAXS). The tris(3,4,5-trialkyloxy)phenyl functionalized derivatives 11b-e showed broad mesophases for a minimum alkyl chain length of C9. The phase widths ran...

The complete dissociation of the hexagonal bilayer structure of Lumbricus terrestris hemoglobin (3900 kDa) at neutral pH, in the presence of urea, guanidine hydrochloride, sodium perchlorate, potassium thiocyanate, sodium phosphotungstate, and sodium phosphomolybdate, followed by gel filtration at neutral pH on Sephacryl S-200 or Superose 6, produced two fragments, II (65 kDa) and III (17 kDa);...

Tetraphenylenes 2 with eight peripheral gallic esters were prepared in two steps from octamethoxytetraphenylene 1 in 19-72% yield. Investigation of the mesomorphic properties of 2 by DSC, POM and X-ray diffraction revealed that derivatives 2a-d with short alkoxy chain lengths (C(5)-C(8)) did not show any mesomorphic properties, whereas compounds 2e-i with C(9)-C(13) chains displayed rectangular...

A 68-year-old man presented with pain and malaise. Laboratory studies showed pancytopenia, hypercalcemia, increased creatinine, and proteinuria. Serum protein electrophoresis revealed an M-spike (0.2 g/dL) and immunofixation confirmed l-light chain. Bone marrow showed sheets of l-light chain restricted plasma cells with readily identifiable extracellular hexagonal crystals on aspirate and biops...

Abstract A two-dimensional magnetic carbon allotrope of hexagonally arranged fused pentagons is theoretically predicted through the copolymerization benzene and spiro[4.4]nonatetraene. The hexagonal spiro-graphene has ferromagnetic antiferromagnetic phases as its respective ground metastable states, two states being almost degenerate in energy because Dirac band at Fermi level narrow. polarized...

in this thesis protic and aprotic ammonium-based ionic liquids were synthesized and their surface tensions were measured in the range of 298-373k. the protics are alkyl ammonium-based ils with the carboxylate (formate, acetate, propionate) anion and aprotics are quaternary ammonium-based ils with bis(trifluoromethylsulfonyl)imide anion. capillary rise method was used for surface tension measure...

Using the first principle methods, we proposed a series of three-chain boron cages B6n+14 (n = 1-12) which are mainly built by fusing three boron semi-double-rings. Their simple geometric structures (approximate D3 or C3 symmetry) facilitate their bottom-up syntheses from the hexagonal B7 and the double-chain boron clusters, such as B2, B4, B6, B8H2, B10H2, B12H2, and the double ring B20. The s...
