Mixtures of cetyltrimethylammonium tosylate (CTAT) and sodium dodecylbenzene sulfonate (SDBS) in water form a fluid lamellar phase at < or = 40 wt % water but surprisingly turn into viscous gels at higher water fractions. The gels are characterized by spherulite and other bilayer defects consistent with a low bending elasticity, kappa approximately k(B)T, and a nonzero spontaneous curvature. Ca...

Understanding adhesion of micro-particles particularly microcapsules containing a functional active on fabric surface is crucial to effective delivery of the active to the latter. Fabric surface is very rough, and direct measurement of the adhesion of single micro-particles on surfaces with roughnesses greater than the particle diameter can be difficult. In this work cotton films were successfu...

* Present address: 1 We have extended the validity of the correlation between the surface 3d core-level shift (SCLS) and the surface d band shift (SDBS) to the entire 4d transition metal series and to the neighboring elements Sr and Ag via accurate first-principles calculations. We find that the correlation is quasilinear and robust with respect to the differencies both between initial and fina...

Nowadays, there is an enormous demand for constructing housing that needs to be catered a short span of time, with minimum transportation costs and in ecological manner. Biobased materials are considered promising resource buildings the twenty-first century due their sustainability versatility. This article discusses biopositive low-cost renewable “green” technologies used low-rise multi-functi...

Efficient demulsification is vital for the application of emulsified asphalt in road construction. In this paper, effects main chemical components aggregates (CaCO 3 , MgO, Fe 2 O SiO Al ) on process were studied by experiment and simulation using a Gompertz model. The findings indicate that surface energy, specific area, pH are most important factors influencing speed asphalt. choice aggregate...

Hot subdwarfs in close binaries with either M dwarf, brown dwarf or white companions show unique light variations. In hot subdwarf we can observe the so-called reflection effect and ellipsoidal modulation and/or Doppler beaming. Aims. The analysis of these variations be used to derive mass radius companion hence determine its nature. Thereby assume most probable sdB derived by fit spectral ener...

Abstract The prevalence of sleep-disordered breathing (SDB) is reportedly very high. Among SDBs, the incidence obstructive sleep apnea (OSA) higher than previously believed, with patients having moderate-to-severe OSA accounting for approximately 20% adult males and 10% postmenopausal women not only in Western countries but also Eastern countries, including Japan. Since 1998, when health insura...

Sila- and germafluorenes containing alkynyl(aryl) substituents at the 2,7- position are strongly emissive with high quantum yields in organic solvents. Provided they sufficiently soluble water, their hydrophobic structures have potential for many biological industrial applications detection characterization of lipophilic structures. To that end, emission behaviors previously synthesized bis[alk...

We have analysed the kinematics of a sample of 114 hot subdwarf stars. For 2/3 of the stars, new proper motions, spectroscopic and photometric data are presented. The vast majority of the stars show a kinematic behaviour that is similar to that of Thick Disk stars. Some stars have velocities rather fitting to solar, i.e. Thin Disk, kinematics. About ∼15 objects have orbital velocities which dif...
