Densities, structural effects and viscosities of binary nonelectrolyte systems including nitrobenzene + 2-propanol, 2-butanol and 2-pentanol at temperatures (293.15 to 323.15) K and normal atmospheric pressure were measured using an Anton-Paar SVM 3000 stabinger viscometer. Excess molar volumes  and viscosity deviations Δη were calculated and correlated by the Redlich-Kister equation to estimat...

Hyphenating High Temperature High Performance Liquid Chromatography (HT-HPLC) with High Temperature Size Exclusion Chromatography (HT-SEC) (High Temperature Two Dimensional Liquid Chromatography (HT-HPLC x HT-SEC or HT 2D-LC)) leads to an isocratic elution in the second dimension, which in turn enables to use IR detector (quantitative detection) for monitoring the eluting polymers. Experimental...

In augmented reality diffractive waveguide technology, the light field needs to be collimated before being transmitted into waveguide. Conventional schemes usually require additional collimating optics collimate from micro-image source and guide it in-coupling elements. order meet of head-mounted devices further miniaturize equipment, this paper proposes a device that combines collimation coupl...

Two series of banana-shaped liquid crystalline (LC) H-bonded complexes HPm/CBn (i.e., bent-core H-bonded sidechain homopolymer HP mixed with bent-core covalent-bonded small molecule CB) and CPm/HBn (i.e., bent-core covalent-bonded side-chain homopolymer CP mixed with bent-core H-bonded small molecular complex HB) with various m/n molar ratios were developed. The bent-core covalentand H-bonded s...

The polymerization of partially methylated β-cyclodextrin (CRYSMEB) with epichlorohydrin was carried out in the presence of a known amount of toluene as imprinting agent. Three different preparations (D1, D2 and D3) of imprinted polymers were obtained and characterized by solid-state (13)C NMR spectroscopy under cross-polarization magic angle spinning (CP-MAS) conditions. The polymers were prep...
