It is commonly assumed that the structure of water at a lipid-water interface is influenced mostly in the first hydration layer. However, recent results from different experimental methods show that perturbation extends through several hydration layers. Due to its low light penetration depth, attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy is specifically suited t...

The structure and rheology behaviour of gels produced by water dispersions of a vitamin C-derived surfactant (ascorbyl-6-O-dodecanoate) were investigated by means of SAXS and rheology experiments for the first time. The gel state is formed upon heating and is due to an anisotropic expansion of the tightly compact lamellar structure. The phase transition involves primarily the melting of the alk...

Four new oribatid mite species of the superfamily Galumnoidea, Pergalumna paradecoratissima sp. nov., Pergalumna paralongisetosa sp. nov., Pergalumna ecuadorensis sp. nov. and Galumnopsis lanceosensilla sp. nov., are described from Ecuador. The genus Galumnopsis is recorded for the first time for the Ecuador. Pergalumna paradecoratissima sp. nov. is very similar in having the combination of fov...

Swedish truck industry is investigating the possibility for implementing the use of Compacted Graphite Iron (CGI) in their heavy duty diesel engines. Compared to the alloyed gray iron used today, CGI has superior mechanical properties but not as good machinability. Another issue that needs to be addressed when implementing CGI is the inhomogeneous microstructure when the cast component has diff...

The effect of microstructure and strain rate on the room-temperature (RT) 700 °C compression deformation behavior a powder metallurgy processed ?-TiAl intermetallic alloy, Ti-45Al-2Nb-2Mn (at.%)-0.8 (vol%) TiB2, was investigated. Samples were heat-treated to obtain duplex two-phase ?2+? two nearly fully-lamellar microstructures with different lamellar spacings ?-phase volume fractions. Compress...

Scanning laser melting was employed to investigate directional solidification in Al–Cu thin films, 200 and 500 nm thick. The alloy with both eutectic hypoeutectic compositions, were co-deposited on fused silica substrates by magnetron sputtering. Melting of the films carried out air using a CW laser, as function scan velocity, v, up 5 cm/s. For regular lamellar microstructure observed over enti...

PURPOSE Congenital stromal corneal dystrophy (CSCD) is characterized by stromal opacities that morphologically are seen as interlamellar layers of amorphous substance with small filaments, the nature of which has hitherto been unknown. CSCD is associated with truncating mutations in the decorin gene (DCN). To understand the molecular basis for the corneal opacities we analyzed the expression of...

Three new oribatid mite species of the superfamily Oppioidea--Cycloppia asetosa sp. nov., C. spindleformis sp. nov. and Hammerella (Hammerella) excisa sp. nov.--are described from India. The genus Cycloppia and subgenus Hammerella (Hammerella) are for the first time recorded in India. Cycloppia asetosa sp. nov. differs from all species of Cycloppia by the rostrum with indentation and the absenc...

Interlamellar plastic discs inserted into cat corneas provide a means by which segments of the cornea can be studied with regard to swelling and water movement in vivo. The corneas are physiologically normal as demonstrated by their transparency, swelling properties, and histologic structure. The observation that one disc causes no change in the hydration of the stroma anterior or posterior to ...

The syntheses, structures and magnetic properties of the coordination compounds of formula [FeIII(acac2-trien)][MnIICrIII(Cl2 An)3]·(CH3CN)2 (1), [FeIII(acac2-trien)][MnIICrIII(Br2An)3]·(CH3CN)2 (2) and [GaIII(acac2-trien)][MnIICrIII(Br2An)3]·(CH3CN)2 (3) are reported. They exhibit a 2D anionic network formed by Mn(ii) and Cr(iii) ions linked through anilate ligands, while the [FeIII(acac2-trie...
